A journey of Shadowverse and Honkai Impact 3rd

"We were already very happy to get along, Sister Mono."

In response to Mono's smile, Sera also offered her friendliness. In addition, she also asked about the accuracy of the information provided by Lucas.

"Oh, Sister Mono, when I was out, I met a demon named Lucas who claimed to be a historian. He said there's another settlement of indigenous people about 350 kilometers away from Eyalon..."

With the help of Mono, Sera called up Eyalon's database and marked a straight line on the light and shadow projected in front of the two people. She then explained the information she got from Lucas.

But for Mono, that area was really unbelievable. According to Eyalon's data records, there should be no settlement in that place.

In addition, Sera's understanding of Eyalon seems to be wrong...

128. Tianhai Center

Tianhai Center.

Yeloin

It is a key area for communication between the planet's outer space and the cities on Earth. Around the transportation structure called the space elevator, a prosperous logistics industry and industrial park were born. Similarly, when the disaster came, the war that broke out there was also extremely brutal.

The giant structure of tens of thousands of kilometers collapsed in an instant, turning into a burning meteor falling from the sky, and the scorching flames of the exploding aircraft and the huge body of the falling mecha became a corner of the tragic world. It was burned down under the attack of the alien creation and became the nest of the dead where the undead now wander.

Mono's computing circuit retrieved data and read the information very quickly. After a while, she confirmed that the area Sera mentioned was indeed the center of Tianhai, the terrible undead nest. As for Lucas, who claimed to be a historian, he did have some records about it.

"Yeloin, the center of Tianhai... Honestly, according to common sense, there shouldn't be a settlement there. Too many undead skeletons and malignant organisms occupy everything on the surface and underground."

"But if the Lucas you mentioned is an elderly gentleman, Sera, then his words do have some credibility. Back then, when Eyalon was defeated, he did guide us and help us evacuate."

Recalling that Eyalon had once fallen under the siege of creation, the Mind Machines rarely established a cooperative front with the dictatorial ruler. Unfortunately, no matter how strong their will to resist was, they still could not escape the huge scale of the enemy.

"However, we only knew that he was a life form from another world and did not know that he was a demon."

The exchange of information ended after the mention of neutral forces. Sera's thoughtful expression was reflected in Mono's light-colored eyes. As a result, they were secretly surprised by the information provided by both sides, which made the actual situation of this planet even more confusing.

The mysterious demon historian, the hidden indigenous stronghold in the center of Tianhai, and the neutral forces that never appeared in Eyalon's sight...

This is really becoming more and more interesting, and it makes people feel more and more that there are other hidden stories behind this world that is about to end.

"Sister Mono, are you ready to find out the authenticity of this information?"

When it came to the specific matters, Sera still asked even though she knew what the answer would be.

"We have the will but not the strength. Right now, Eyalon is in ruins, and we are already doing our best just to keep the underground facilities running."

The pleasant voice stated the facts calmly. Just as what was said, Mono did not intend to use the power available to Eyalon to find out the truth of the information. The long march of more than 350 kilometers was no less than a final journey towards death.

Even though Eyalon will die in the end, there is still a difference between dying early and dying late.

"Indeed, what Eyalon needs most right now is stability. In that case, let's rest for a while. I'll go over there and take a look. When I find out what's going on, I'll come back and tell everyone about it."

"If a settlement really exists, perhaps the forces of both sides can complement each other."

It was like chatting about daily life. What seemed powerless to Mono seemed not dangerous to Sera. After all, she might not be able to defeat some powerful creation models, but running away was her forte. As long as she was not bound by things she cared about, Sera had a very flexible escape plan.

"Hmm~" Mono quietly looked at the confident girl in front of him, and the pretty charm on his face suddenly became a little helpless. He closed his eyes and sighed slightly, looking particularly playful. "As an outsider, you can contribute so much to this place. Sera, you are really a difficult person to deal with."

"Eh, tricky, are you describing me? That doesn't seem right, Sister Mono."

Sera's cute face was full of smiles, and she was ready to find out the situation. Her face was full of ease, without any solemnity of doing something big.

"Of course, selflessness is a quality that always makes people feel apprehensive. What kind of reward would be worthy of the help you give to everyone?"

With a plan in mind, he fully recognized this distinguished guest who had a good relationship with his sister Annie during his communication with the girl. The reward prepared by Mono could be said to be Eyalon's most powerful technology.

"Please connect and I'll send you the technical information for [Original One]."

"This is the key technology that makes up my body. Little Sera, you must use it well~"

beep beep...

The data transmission speed is very fast, but it takes a long time. Once the technology called "Original One" was used, Sera, who had taken a few glances at it, felt inspired.

While the body is fixed and the materials remain unchanged, the body's quality is sublimated and its output is increased. The magical operating circuit changes with random energy. This technology can be called mechanical evolution, although this is not normal.

"Okay, Sister Mono, I will make good use of it. Then, I'll leave first~"

"Have a safe trip, sweet little one."

The afterglow of the space transmission spread in the factory room, and was then captured by the sophisticated sensor. It was stopped by Mono when it was about to trigger the alarm. After that, the smiling Jiu Chang Crimson temporarily returned to the shutdown and self-check state, cooperating with the factory's automatic equipment to repair and upgrade its own body.

The originally quiet factory slowly returned to its former normal state of bustle. In the successive activities of the precision machinery, in addition to Mono, several powerful models are also being strengthened and reshaped. In order to cope with the future storm, the machines are also working hard in their own way.

.........

Time passed by minute by minute. Sera rested and meditated well in the room assigned to her by Eyalon, checking the newly obtained information. In the surge of inspiration, Sera felt itchy and wanted to apply the technology of "One of the Originals" to her own machine that had not yet been finalized.

Moreover, Sera felt that if she could fully understand the connotation of the technology, its principles should also be applicable to golems and even puppets. Although there might be problems with adaptability, it would still be amazing enough.

The flickering virtual projection in the blue eyes ended instantly. The shutdown of the wrist computer was a sign that Sera was ready to leave. After sending messages to friends such as Anier and Nicola, saying goodbye another day, she moved very quickly to leave the room where the warmth was still lingering, and left Eyalon who lived in the basement.

On the surface, the diligent ancient creation was still scanning everywhere, with a subtle sense of fit like a prospector. If it weren't for the enemy, Sera would have felt quite friendly towards the creation. If she had the chance, she might even get one and disassemble it to see what technology it used.

The Holy Green Mana concealed its own existence and sneaked in the gaps of space, like a fish swimming in the sea. The freely flying Sera disappeared from the world in an instant. The strange and unwavering movement method seemed to be three points as exquisite as the movement of the demon Lucas.

129. Hopeless Hell

Traveling through the dim, ruined world, witnessing the end of the defeated world, the barren rock and soil are mixed with rusty iron filings, the pale red color is like blood, occasionally turned out and then buried mercilessly in the ground, as if this no longer highlights the despair that permeates the planet.

The thick black clouds changed their appearance, spreading from top to bottom in layers, like layers of black vortexes in an inverted pyramid, with cold green lightning interwoven around the edges. The resentment emanating from them had already invaded Sera's eyes from dozens of kilometers away.

At this point, Sera also had doubts.

Is there really an indigenous stronghold in that so-called center of the Sky Sea? Or have they mastered the technology to avoid the perception of the dead and built their own utopia in the lair of the dead that even creatures don't want to visit?

No trace of the Creation's activities was found within a radius of several kilometers, and no iconic energy core was visible. Sera, knowing that the Creation would not attack the mindless undead, frowned, because watching from a distance did not provide even a possible clue to her thoughts.

Or do we have to go in and explore to find out whether it is true or not?

According to her own ideas, Sera estimated that even if there was a stronghold, it should be underground, blocked by positions, solid walls and other things to ensure the normal operation of the stronghold. At the same time, there should be a team communicating with the outside world, going to the outside world from time to time to search for resources.

Industrial Park and Logistics Center...

If I remember correctly, Yeloin, the center of Tianhai, has such a positioning. If you ignore its unfavorable status as a monster base, it is indeed a resource-rich and good place...

The round-toed boots stepped on the land far away from the city. The cracked road was stained with a different dark color. Its listless appearance seemed to be dead, but in fact, that was the posture of grass leaves in an environment with strong negative energy.

Growth is for withering. Indifferent birth is commonplace here, and calm and indifferent death is shelved as an almost impossible luxury. In the short life of black grass, the sudden and rapid withering is precisely to transform life into death, making the smell of decay here even more intense.

He bent down and picked up a blade of grass. The feeling of decay had just taken root in Sera's injury when it dissipated like the wind.

The grass blades turned into black snow and ruthless sand, flowing through Sera's fingers, not daring to accompany the pure and peaceful life.

"..."

Above the head are layers of whirlpools swirling and lingering, and under the feet are dilapidated and deserted roads. There is no blue sky above and no loess below, and all around are collapsed and weathered ruins.

I stood up and walked towards the center of the city, also towards the pillars of heaven and elevators that once stood there. Slowly, the road, which was covered with cracks and overgrown with weeds, became unrecognizable. There were puddles of water everywhere, and the wreckage of simple aircraft destroyed all traffic.

"..."

The invisible new wind comes from the Holy Green Mana, which is incompatible with this place. The traveler who controls the wind walks on the barely passable road. Wherever he passes, obstacles move by themselves, lifted and transferred by the invisible new wind, making way for Sera to a path of corruption.

Then, Sera saw a straight rift valley, which lay lifeless in the city, running from east to west. There was no reflection at the bottom of the deep valley, like a slender corpse, showing how hot the light descending from the sky was.

The outflow of thoughts formed dreamy spots of light in the outstanding eyes. The dark green color was the symbol of the undead. At a glance, Sera saw their disordered thoughts in the dreamy vision.

The dead valley, nothing can describe the rift where these dead people who have resurrected with despair gather.

Raising her sight, she caught sight of the other side of the rift. The distance of two or three kilometers passed in a flash. Sera, who had reached the other side, glanced down. In front of her were countless dead bodies moving around like a kingdom.

One after another, mechanical claws and feet hooked up to the long dragon-like body, and the train with human skeletons grew out of it and spewed out dark green steam, no longer as bright and clean as before.

The mecha with exposed wiring trampled over the tiny vehicles with stiff steps, causing the vehicles that had just been moving to fall into death again, allowing the filthy souls to rest in peace...

But it only takes a certain amount of time for them, as carriers of resentment, to revive again, either as hungry beasts wandering the world, or as the body of another undead soul.

Sera was not discovered by them. If possible, she didn't want to discover them. In this way, she could at least have more hope for this place, instead of being unable to muster any energy except sighing like now.

Hiding her body and precisely controlling her perception range to about a hundred meters around her, Sera needed to be more careful in order to move in the increasingly demonic nest, otherwise a small mistake would make her the target of public criticism.

The tattered underground entrance was pitch black and it was difficult to see anything. The unpleasant smell carried back and forth on the rotten wind, causing the girl who smelled it to frown involuntarily, and then she weaved a small spell to purify the nearby gas.

Going down from the entrance of what should be a subway facility, the extremely long staircase was filled with small undead. Morbidly white bones and twisted and rotten mechanical components were intertwined, forming a cold jungle of the dead. The situation where there was almost no place to stand made it difficult for Sera to find a gap to pass through.

So, she gave up the idea of ​​diving into the unknown underground. Now, she planned to find a temporary base on the surface to build a barrier so that she could have a place to rest and eliminate the mental stress brought by seeing death everywhere.

Back on the surface, the scene of demons dancing in disorder is still being played out. On the ground are either creaking vehicles of all kinds or sturdy white-bone giants. It is rare to see pure ghosts. The sky is also their paradise. Flying vehicles with bone spurs and flesh and blood are drawing strange curves, and the plasma plumes they eject are also an ugly gray-white color.

The dense negative energy was dead silent, almost motionless and solidified in every inch of the air, but the undead created were "full of vitality", venting endlessly and aimlessly violently.

Even after death, there is no rest...

Sera remembered a joke, but she felt that what she saw was not funny at all. Apart from the bone-chilling cold, she could not find any hope.

Searching for an area in the ruins that could serve as a stronghold, perhaps because the materials used here were very strong, there was a relatively intact basement under the ruins of the building, which made Sera feel a little relieved.

All things related to the undead were directly teleported into an unknown place in the distance. Sera, who had set up a micro barrier, sat on the bare bed frame. Wherever her eyes went, fire suddenly appeared. The light of the holy blue brought light to the basement and illuminated the girl's gentle face.

——This is my first day at the Tianhai Center "Yeloin", and I haven't gained anything so far.

130. Mathematical Demon

——It is now the fourth day since I arrived in Yeloin, the center of Tianhai. In the ruined city, I have not seen any trace of any possible settlement.

I have no idea whether they hid too deeply or the stronghold that the demon historian mentioned does not exist at all.

But based on my observations over the past four days, in addition to learning more about the unique ecology under the siege of death, I seem to have found some strange clues.

It might be a settlement, but even if it was a settlement, it was a settlement of the dead. The resentment, longing, and other things of the past underwent a phenomenon similar to reincarnation and transformation in such a sad environment, giving birth to the dead with minds.

Based on some clues, I decided to go and see the place where the deceased might live.

Hopefully, there I might find some clues about possible Aboriginal strongholds.

.........

In the underground where the dead live, black mosses soaked in moisture are scattered here and there, climbing on the walls and ceilings. Compared with facilities similar to subway stations, there are no piles of small undead here, but it is a bit cleaner.

A cold air blew slowly, filled with all kinds of strange smells, like the bitter medicinal smell of crushed grass and wood, or the pungent smell of burning scalding iron. As far as the sense of smell was concerned, it was not pleasant at all.

The holy blue flame illuminated the road ahead. Under the cover of moss, some text signs vaguely showed the previous use of this place. According to Sera's understanding, the meaning of those signs was very clear.

Civil defense project.

Important facilities that can guard against sudden enemy attacks, effectively shelter personnel and supplies, and preserve war potential.

Unfortunately, along the way, the damaged gate and broken walls showed that this place has not been maintained. Although it is not covered with a thick layer of dust, the equipment is no longer usable.

The bright flame illuminated the way ahead, and the sound of footsteps broke the loneliness of the entrance. Before long, a tight security door appeared in front of Sera. There was also an authentication device on the wall next to it. Although it seemed that only an answer needed to be entered, it was not easy to get the required answer.

"..."

A branch was attached to the side of the authentication device, with clearly written, standard numerical symbols on it, used to identify the visitor...

Isn’t it a bit strange to use a test on partial differential equations as an admission ticket?

Sera complained in her heart. The question in front of her reminded her of the calculation of dosage in alchemy. The tedious calculation steps made her more and more discouraged as she tried to solve the problem. But fortunately, the equation in front of her was within her solvable level.

With the excitement of finding the clue and a little helplessness in facing the math problems, the clever girl opened the document and calculator on her wrist computer and began to solve the math problems with great difficulty as a courtesy to her visit.

The thread of thought extends and grows within the framework of numbers, gradually becoming strong and tall from a lonely seed. The lush branches and leaves connect all the clues in the digital world, and finally produce rich fruits with unique mathematical beauty.

After some effort, he figured out the general solution and input the beautiful characters into the authentication device. After a while, with the sudden lighting of a bright light, the door leading to the depths of the civil air defense project opened, presenting an endless and vast space before Sera's eyes.

It was an empty underground space. No supplies could be seen in the vast area. Although there was bright light, indicating that the electrical equipment was operating normally, it was still too empty.

Four huge columns rise from the ground, supporting the vast and glowing ceiling. The simple industrial atmosphere is without any unnecessary decoration. An indifferent loneliness hovers in this area, like an invisible ghost that can drive people crazy over time.

She walked around the edge of the cylinder that blocked her view, and checked for any possible clues in the underground space that she could see the edge of. Not surprisingly, she looked back and saw the closed security door. Sera, who had been frowning, let go of her perception and let the fluctuations of her spirit echo in the space. After a while, her expression relaxed.

Because she did find something interesting.

Behind one of the arms, there was a dark machine that was out of tune with the bright lights around it. The tall and thin prismatic structure looked like a container containing something. When Sera tried it, she unexpectedly took out a deck of toys similar to playing cards from it.

With beautiful fingers, he pulled out a card and examined it carefully. The clown-like pattern was slightly sad, and to say it was funny was not enough to describe the expression on his face. When he paid more attention to the well-made card back, he found a string of beautiful handwriting.
