Who says a sickly daughter can’t break through the weirdness?

Shen Qinyin frowned slightly, and the millions of threads of mental power arranged in the void remained on alert.

She narrowed her eyes and carefully observed the mysterious figures that were slowly approaching.

Those dark figures looked particularly strange in the moonlight. They moved forward in unison, as if they were controlled by the same consciousness.

The mysterious figure walking in front suddenly stopped, slowly raised its arm, and made a move that no one expected.

It removed the metal mask covering its face.

"this......"

The moment she saw the other person's face clearly, Shen Qiyin couldn't help but show a look of surprise.

Revealed beneath the mask was a face that looked no different from a human.

But those eyes were as black as ink, without any whites, like two bottomless black holes.

Shen Qiyin could feel its "gaze" roaming over them. Half a minute later, these mysterious human figures seemed to be sure that they were different from the strange beasts and retracted their blades.

Then, they slowly raised their hands and pointed in unison towards the depths of the underground passage, as if indicating that they could enter.

"Qiyin, what are they doing..." Tang Miao lowered his voice, his tone trembling slightly and uncontrollably.

"Don't let your guard down," Shen Qiyin warned, maintaining a high level of alert. "Don't forget, these guys just wanted to chop us into minced meat."

As soon as he finished speaking, the leading figure suddenly raised his right arm towards Shen Qinyin and the others, with his five fingers pressed together meticulously, and the movement stopped neatly beside his temple.

Everyone who saw this action widened their eyes in shock again—

These guys were clearly saluting them!

Moreover, it was a fairly standard military salute!

The next second, all the other figures raised their right arms in unison as if they had received a silent command. More than a dozen military salutes were frozen in unison in the moonlight, as if a well-trained army was being reviewed.

Before Shen Qinyin and the others could make any move, the figure in front of them disappeared in an instant like a sandstorm, giving people a sense of ritual of dust returning to dust.

A cold wind blew from the depths of the passage, sweeping up the sand on the ground and forming a fleeting vortex in the air.

In a trance, Shen Qinyin seemed to see the last posture of the leading human figure again. Its black hole-like eyes seemed to want to convey something, but it had no language function and ultimately could not express it.

"Qiyin, what's wrong with you?" Tang Miao noticed the tears flowing unconsciously from the corners of Shen Qiyin's eyes and asked in surprise, "You, are crying?"

"Huh? Is there any?"

Shen Qinyin belatedly wiped the corner of her eyes and indeed felt wet tear stains.

"Oh, don't worry, it's just some sand in my eyes."

"Yeah?"

"Well, let's go." Shen Qiyin retracted her gaze and turned to the entrance of the underground passage. Her voice was low and firm. "No matter what they are, our destination is down there."

As she spoke, she floated into the passage first.

She pretended to be calm and composed, but her mind kept recalling the actions of the previous humanoids.

Although it's the same military salute, why does it feel so familiar to me...

Seeing them disappear, I actually felt a very sad feeling in my heart.

Oh, is it because I have too strong an ability to empathize?

No matter what, the answer must be hidden underneath. You'll find out when you go down.

The metal steps of the underground passage echoed dully under Kana's boots. Each step was covered with thick dust. As everyone went deeper underground, the damp and decayed smell hit them in the face, mixed with the fishy smell of rusty metal and the burnt smell of aging electrical components.

The walls on both sides of the passage were covered with dense cable trenches and ventilation ducts. Some of the ducts had long since ruptured, revealing the pitch-black interior, where the complex mechanical devices within were vaguely visible.

This place has clearly not been abandoned for long, but it feels like it hasn't been maintained or used for over a decade.

The markings on the walls had long since faded, but some remaining symbols and red-painted warnings such as "Danger: Supercritical Reactor" and "Radiation Zone: No Entry" could still be made out.

The protective clothing that Shen Qiyin upgraded for them naturally also has the effect of resisting radiation. The only thing that needs to be mentioned is that Kana still refuses to sacrifice her "beauty" and wear these bulky clothes as before.

Her physical condition cannot be measured by common sense, and she is not an idiot. If the radiation really has any effect on her, she will say it out.

As they continued to go deeper, the temperature gradually dropped, and a thin layer of white mist filled the air. The flashlight beam hit the mist, scattering an eerie blue-green color.

"The radiation levels are abnormal, the concentration is too high." Xiaoxiang's pupils flickered slightly, and his voice sounded more serious. "My Geiger counter is ticking. From a rational point of view, I don't recommend staying in this place any longer."

Before he finished speaking, the view in front suddenly opened up, revealing a wide circular hall.

A huge reactor device occupies the center, its surface covered with a thick layer of gray-white rust and dotted with cracks, as if it would collapse at any time.

There were several obvious burn marks on the reactor's outer shell, which appeared bluish-purple, as if it had been burned by some strong light.

Thousands of coolant pipes crisscross the ceiling, looking shocking.

Several thick cooling pipes are hung above the reactor. The inner walls of the pipes are covered with black oil stains. Some pipes have been broken, and dark green liquid is slowly dripping, splashing irregular foam on the metal floor.

The metal panels on the floor have warped and in some places have melted, revealing the concrete structure underneath.

Shen Qinyin turned her head and looked around. In addition to the huge reactor device in the center, there were four control cabins distributed in the four corners of the hall, each of which was protected by thick glass.

The glass of the central control cabin was completely shattered, and some broken instruments and documents were scattered inside.

She went forward and picked up the documents. The text on them was blurred, but some diagrams and symbols were still recognizable, like a flowchart of some chemical reaction.

"Qiyin, look at that!"

Suddenly, Tang Miao's muffled voice came from behind Shen Qinyin through the protective suit.

Shen Qiyin looked in the direction of the sound and saw that Tang Miao's flashlight was shining on a miniature nuclear reactor device.

This device stands quietly on an abandoned metal base, its surface covered with complex cooling pipes and heat sink fins. Although the outer metal shell is partially covered with rust, it still cannot conceal its unique design beauty.

"Miniature nuclear reactor, model 'Polaris-β'."

Shen Qinyin stared at the nameplate on the device and whispered the name of the device.

There was a hint of unconcealable joy in her voice. With the miniature nuclear reactor, her Titan could finally be further upgraded.

"mona."

Shen Qiyin called softly, and the black shadow transformed by Mona suddenly appeared out of thin air, moved along the surface to the front of the miniature nuclear reactor device, and swallowed it into the independent space it created.

In addition to the reaction device, the storage compartment next to it also stores some semi-solid metal blocks.

The surface of these metal blocks is dark gold and emits a faint fluorescence. There is no doubt that they are the nuclear fuel that starts the reaction device.

Through the radiation-proof storage cabin, Shen Qinyin carefully observed the fuel blocks.

Their shapes were quite complete, and compared to the nuclear fuel she knew, these fuel blocks were obviously denser, and the surface was covered with a transparent outer layer similar to crystals, emitting a strange luster.

"Scanning."

Xiaoxiang gently poked her temple with his finger, and then his eyes projected a scanning net, sweeping across these solid fuel blocks from top to bottom.

After a while, she said, "The scan is complete. This nuclear fuel block is 'high-density enriched crystalline nuclide fuel.' According to the database comparison, this fuel density is at the theoretical limit of third-generation nuclear fuel currently known to mankind. It is a mixed core of ultra-pure enriched uranium-238 and plutonium-239, and its density has been increased by more than three times through a special catalytic process.

This special process is quite complicated. My database does not have any relevant records. I guess it is a secret technology mastered by the state..."

"Shh!"

Before Xiaoxiang could finish his words, Shen Qiyin suddenly raised her index finger and made a gesture of silence.

The latter quickly closed his mouth and showed a vigilant attitude.

Tang Miao, who was beside her, also keenly noticed the abnormality around her. She couldn't help but move closer to Shen Qiyin and whispered, "That energy fluctuation seems to have suddenly become active."

"Yes, and it's very close to us."

Shen Qiyin concentrated her mind, and her perception network turned into strands of silk threads, spreading along the source of the energy fluctuations, and finally stopped underground behind the central reaction hall.

She nodded to the others and took the lead in flying towards the source of the energy fluctuations. After a while, the group arrived at a huge open area.

This area seemed to have been used to store various supplies and related equipment and maintenance tools. Because it was abandoned so suddenly, a considerable amount of equipment and tools were not taken away.

Strangely enough, the structure of this open space is quite strange.

The ceiling here is extremely high, like an underground palace. The surrounding walls are inlaid with complex gears and metal structures. Although most of them have rusted, the sophisticated design of the past can still be seen.

The designs they saw were completely different from the design styles they had seen along the way.

It feels as if this vacant land has undergone another transformation on the original basis.

But these are not the point.

What really caused fear and shock to Shen Qinyin and the others was a huge door standing at the back of this empty underground square.

The door is about twenty meters high and eight meters wide. It is made of what looks like some kind of synthetic metal, and its surface is covered with complex patterns that resemble the symbols and patterns of some ancient civilization.

The most surprising thing is that this door seems to be completely detached from the architectural structure of the base. There is no connection between its edge and the wall, as if it appeared here out of thin air.

If the other party did not have that strong cognitive pollution and murderous intent, Shen Qiyin's first reaction would have been that she had met the lurker's "fellow disciples."

"What's going on with this door?"

Lin Qiutang's pupils shrank slightly. She had never seen such a design before.

The material of this door is out of tune with everything around it and does not look like an item from this base at all.

"This door... seems to have appeared after the base was abandoned!" Tang Miao's voice came from inside the protective suit, with unconcealed surprise and solemnity. "I can feel that this door is completely incompatible with this nuclear test base. Also, its energy fluctuations are very similar to those mysterious humanoids we just encountered... No, they are exactly the same!"

"The thing behind this door...may be related to those mysterious humanoid figures." Shen Qinyin expressed the same idea as Tang Miao.

As soon as she finished speaking, there was a slight vibration in the air, as if something was awakening from deep underground.

The blue light between the cracks in the door began to grow brighter, and even began to condense along the edge of the door, forming a strange halo.

Shen Qiyin's eyes flashed, and her mental power quickly surrounded her.

She raised her voice and warned everyone, "Be careful, there's something in there, it could be an enemy. If we can't handle it, we'll flee!"

"Understood!"

The halo of the giant gate became brighter and brighter as the blue light condensed, and a low resonant sound began to echo throughout the empty room, as if every brick and stone of this underground base was vibrating.

At the same time, the blue light in the air began to grow stronger, eventually converging into a beam of light that shot straight into the darkness above the ceiling.

The moment the beam of light touched the ceiling, the entire underground base was instantly filled with that powerful force!

A huge amount of psychic energy surged within the underground space. Wherever Shen Qiyin's eyes reached, the tangible psychic energy values ​​began to rise rapidly.

3000, 5000, 10000, ...

15000, 20000...

About half a minute later, the rate of increase in the value gradually slowed down, stopped at the node of 22000, and then slowly decreased, and finally stabilized at around 5000.

This number is already quite terrifying. You know, even the Black Tide clone that was blown up by himself with Megatron only had a psychic reaction of about 8000!

And in the crack of the door, the blue light finally gathered into a complete form, and the whole door began to slowly open, revealing the darkness behind the door.

The darkness swallowed up all the light, but Shen Qiyin could still feel a strong energy fluctuation overflowing from it.

The oppressive feeling far exceeded any threat she had encountered before. The mental threads she used to arrange the spatial killing method spread rapidly in the air, but it was like hitting an invisible barrier, suppressing her and making it impossible to move.

As the gap in the door grew larger, some blue light seeped out from behind the door, and the scene behind the door was finally fully revealed to everyone.

When they saw the scene before them, everyone gasped.

It was a huge circular area with a diameter of thirty meters, and the ground was covered with dense and complex runes.

Shen Qiyin noticed that these runes looked quite familiar, very similar to Chinese characters, but completely unrecognizable. It felt to her as if they were new characters created by deliberately adding various strokes to Chinese characters and then mirroring them.

Perhaps this is the ancient writing of this world?

The surging energy inside the door seemed to have no hostility towards them. Not only that, Shen Qinyin also had a vague illusion that this place was open and welcomed them in.

With this thought in mind, she took the lead in entering the area behind the door. Others wanted to dissuade her, but after thinking carefully, they felt that if they could find out the secrets of this door and those mysterious humanoids, the danger would be worth it.

As they went deeper into the door, the scene inside was completely revealed.

Behind the door was a huge circular area with a diameter of thirty meters. The ground was covered with dense and complex runes.

In the center of the area, the runes carved into the ground emitted a faint blue light, with lines spreading out from them, interweaving with the runes, and finally forming a complex circular magic circle.

Having come here, Shen Qinyin was already certain that this magic circle was the source of energy for the group of mysterious human figures outside.

By the same token, it can be speculated that this is probably the reason why this area is not covered by fog.

This magic circle protects this land, and the group of mysterious warriors are its soldiers. With its support, they bear the responsibility of eliminating the strange beasts.

Unfortunately, judging from the internal situation, this magic circle probably appeared after the black tide raged.

If it had appeared earlier, perhaps humans would not be in such a mess as they are now.
