My sister is Luna

With the discovery of the first key, it was as if a switch had been turned on, and the keys hidden in the other miracles began to appear one after another.

The key to the Tower of Babel was taken by the three sages as soon as it appeared.

The key to Yunmengze was automatically separated from the reincarnation technique and is now in Guiguzi's hands.

The key to the Dongfeng Altar was jointly owned by the states of Wu and Shu.

News also came from the West that the Sea City held the key to the miraculous Heart of the Blue Sea.

Under the leadership of the Jixia Academy, the parties holding the key held their first meeting in Chang'an, where the Ark was located.

The keys haven't all been collected yet, but all parties are hesitant about whether to open the Ark. The awakening of a god would undoubtedly disrupt the existing order, and no one knows what this god will do. Although Jixia Academy has repeatedly assured that Nuwa is a righteous god who stands with humanity, no one except Jixia Academy has received any information about the legendary fallen god's actions. Moreover, what to do with the Ark's core is also a problem. Regardless of their motives, whichever side persists will possess absolute power to rule the continent, which is something no one wants to see.

With so much involved, everyone except Jixia believes that there is nothing better than sealing it at the moment—that is, maintaining the status quo, holding the key but not opening the Ark.

The city was ruled by the Arcana family, who held differing opinions. Some believed that the gods should not be allowed to interfere with or disrupt the human world, while others wanted to sell the key for a good price and still others felt that they should discuss sharing the gods' legacy.

Especially Empress Wu Zetian, who ushered in a golden age, but she did not want it to end under her rule. The awakening of the creator goddess Nuwa would inevitably cause unnecessary trouble. To put it bluntly, the awakened goddess might even want to re-establish the regime. After all, how could she not want to rebuild such a glorious era? War would destroy the Tang Dynasty's golden age, and she would become a sinner of the Tang Dynasty. As a woman, she would be even more subject to public scrutiny. Wu Zetian, who had finally climbed to the pinnacle of power, would never allow such a situation to occur.

However, she also sent secret messengers to inform the Great Wall Guards to obtain the key. With two wonders within Chang'an's territory, meaning they would have two keys, she would have greater initiative and be able to fight for more benefits for the Tang Dynasty.

The Jixia Academy believed that all countries should unite to face this huge crisis. The Shu Kingdom strongly agreed with this, but the Wu Kingdom disagreed, and a rift began to emerge between the two kingdoms.

Looking at the various factions, each with their own agendas and constantly pulling in different directions, the old master couldn't help but shake his head and sigh. It seemed that more than two thousand years had made people forget the horror of that divine war, and also forgotten what consequences Emperor Jun's return would bring. Being complacent would come at a price, and he had to find a way to unite the various countries.

Because of the matter of God, the connections between nations have become increasingly close.

Amidst these changes, Cain and Luna first returned to the Jixia Academy and obtained the antidote developed by Mozi, thus eliminating the blue toxin.

Then, together with Mulan, they returned to the Great Wall and encountered Milady there.

Milady's enthusiastic hug annoyed Luna and Mulan.

The people at the Great Wall warmly welcomed the three.

For her meritorious service, Mulan returned to the Great Wall Guard and was appointed captain of the Special Operations Team. She was given a great deal of freedom and the authority to mobilize a small number of soldiers, which suited her lone-wolf style. This was a reward that the Empress had prepared for her long ago.

Cain, the great hero who once defended the Wall, was highly sought after and enjoyed great prestige among the Wall Guards. He once refused the Empress's reward, and though he had no power, he was more powerful than anyone else.

Baili Shouyue prepared a large feast to celebrate the hero's return.

"Shen Mengxi, you stole my meat again!"

"Who told you to eat so slowly, meow?" Shen Mengxi snatched one from the left and one from the right, making Baili Xuance bristle.

"Damn it, I'm going to eat, eat, eat!" To avoid having his food stolen, Baili Xuance stuffed the meat into his stomach in a hurry.

"Xuan Ce, you're at an age where you're growing, so don't be a picky eater. Don't just eat meat, you need to eat vegetables too, so you can have a balanced diet." Baili Shouyue put some greens into Xuan Ce's bowl as he was happily eating.

"I know, brother. It's because your cooking is so delicious that I can't stop eating." Every time Baili Xuance opened his mouth, he precisely missed the vegetables in his bowl.

"Come on, open your mouth." Baili Shouyue smiled and put a piece of meat to Baili Xuance's mouth.

"Okay, mmm..." Baili Xuance ate it directly, without seeing or tasting the vegetables under the meat.

"Haha, I often use this trick on my sister too," Cain remarked, having witnessed the entire process.

"Brother...!" Luna blushed.

"Really? It seems great minds think alike," Baili Shouyue said with a smile.

"Yes, she is my sister, Luna. She was very naughty when she was little. She followed me around like a little chick all the time, calling me 'brother, brother' nonstop."

“Xuan Ce, he used to always get into trouble, and then he would always come to me crying afterwards.”

"Sigh, as an older brother, I always have to be tolerant of my younger sister. Sometimes when my younger sister gets into trouble, I have to take the blame for her. Seeing her crying, I feel helpless."

"Yes, the eldest brother is like a father."

"My sister likes to stick to me."

"My younger brother was the same when we were little."

“It is now as well,” Baili Xuance interjected.

Luna was too embarrassed to say it aloud, so she just clung tightly to Cain. Milady ate her meal elegantly, glancing at her with a puzzled look.

The two chatted like close friends, exchanging experiences as older brothers, and discovered that as older brothers, they always had to stand up and protect their younger siblings.

"Haha, hiccup, bro, I saw a butterfly!"

"Xuan Ce, don't drink!"

"Meow hahaha, explosions are art meow!" Shen Mengxi, her face flushed from drinking, rambled on, adding a touch of merriment to the party.

"Tonight is a full moon. I raise my head to gaze at the bright moon, and lower my head to think of my hometown..." Looking at the jade disc of the sky that shines with silver light, Su Lie was filled with countless thoughts.

"Come on, let's drink! Let's celebrate another peaceful day at the Great Wall." Su Lie raised his glass to everyone again.

Raising a glass under the moon, accompanied by the tranquil night, is a peaceful and harmonious experience.

The moonlight gently enveloped the Great Wall, which, like a baby in swaddling clothes, drifted off to sleep.

……

The moon tonight is unusually bright and round, its cool light resembling an indifferent eye.

Silvery butterflies, bathed in moonlight, flew past the soldiers on duty along the Great Wall. Each flap of their wings emitted an invisible ripple that spread throughout the entire Great Wall.

According to records, this is the legendary Cloud Butterfly, which is said to have the ability to grant any wish in the Cloud Desert.

The guards ignored him, not making any excited wishes, but upon closer inspection, his eyes were unusually empty, as if he were lost in thought.

This was not an isolated case, but rather a situation in which all the Great Wall guards were caught in the same predicament, with unknown enemies having breached the Great Wall without the guards' knowledge.

"Brother, brother, over here, over here!" Luna waved her arms.

"Luna?" Cain walked over.

"Brother, let's go play." Luna transformed herself, changing into a swimsuit, with a beautiful scene behind her.

Sunshine, beaches, the sea, and swimsuit-clad beauties—scenes that would make anyone's blood boil—but only Cain got to feast his eyes on it all.

"Cain, we've been waiting for you for a long time." Milady, now dressed in a swimsuit, had a curvaceous figure, and even her mechanical servants looked like "shrimp soldiers and crab generals."

"Cain, come and serve me. Apply your sunscreen all over my body." Wu Zetian, dressed in a dress inspired by the ocean, with her blue hair flowing freely, lay on the cushion, revealing her beautiful back.

"Come and enjoy the summer together!" Luna, Shangguan Wan'er, Yang Yuhuan, Xi Shi, and Jing were all wearing swimsuits, and the group pulled Cain to the beach.

A group of beauties surrounded Cain, watching the different styles of swimsuits that showcased their diverse figures—some innocent, some alluring, some exciting. Cain felt as if she were in paradise.

Is this a dream? It's so erotic! Cain was itching to watch, feeling like he was dreaming.

I'm a perfectly upright gentleman, how could I have such a dream? Is this some kind of erotic dream? Cain felt it was a bit unreal. He knew he was dreaming, but he couldn't quite put his finger on what was wrong with it.

Although it was a rare and beautiful sight, if I wanted to wake up... looking at the frolicking beauties, Cain had the thought of waking up.

Looking at the still summery scene, Cain's expression turned serious.

I was trapped in a dream.

"What's wrong, Cain?" the women who were seducing Cain asked with concern.

Yanmen Pass, the first pass of the Great Wall and also the core pass of the Great Wall, was now wide open, exposing its core to the enemy.

"Is this the heart of the Great Wall? It's so beautiful."

The white-robed sorcerer passed through the Great Wall guards as if they were in an empty place, admiring the ancient, now powerless furnace.

This person was none other than Ming Shiyin, and a stunningly beautiful figure floated beside him.

A crescent moon hung behind her, silvery-white butterflies fluttered around her, her cold eyes looked down upon all living beings, and her skin was as white as snow, like a tall moon goddess.

"Now is not the time to admire; time is limited. Once you find the key, hurry up and leave," the goddess said.

"Of course, Lady Haiyue, I just hope you won't forget our promise."

"God never breaks his promise."

After speaking, Ming Shiyin was about to reach for the square-shaped key that was floating above the power furnace.

"Whoosh—" A dart deflected Ming Shiyin's hand.

“Ming Shiyin, it’s been a long time.” Cain came out.

"Oh? Since someone can break through my illusion, it seems that not all people in this era are fools." Haiyue was somewhat surprised.

The illusion of the moon is so realistic that it can be mistaken for reality. However, the illusion is generated by the human body itself. As long as one is aware of it, one can find a breakthrough point to awaken. This is how Cain escaped.

"Kain, are you going to stop me?" Ming Shiyin narrowed his eyes.

“Ming Shiyin, I know you want the Great Wall, and you’re even willing to cooperate with Dijun, but can you defend it by yourself? Besides, Dijun is a madman. Even if you get the Great Wall, you’ll just become a sacrifice in his hands…” Cain hoped that Ming Shiyin could see the error of his ways.

Ming Shiyin was very surprised, not expecting that Cain would know such information.

Haiyue was enraged. "You madman, how dare you insult my lord! Die!"

In an instant, a moon blade carrying the power of a king shot towards Cain. Cain was very surprised that the opponent was a king, but his own strength was already at the demigod level. He directly cut the moon blade in half with a single slash.

Then he lunged forward and grabbed the two of them in an instant.

Ming Shiyin and Haiyue's figures became blurry, and Cain's expression turned solemn.

A dream within a dream?

The incident involving the moon did not cause any damage to the Great Wall. After Cain escaped, no one on the Great Wall noticed anything unusual, except that Cain was attacked.

The appearance of the moonlit sea indicated traces of Di Jun, and Cain couldn't help but worry about the conspiracy involved.

……

After the moon's attack, the Great Wall remained calm, and the nations slowly began preparing to open the Ark.

It wasn't until a year later that the countries agreed to launch the ark.

This was a secret affair, attended only by key figures from various countries, including the Three Sages and Cain.

Everyone wore solemn expressions as the door slowly opened, and the Ark was unsealed.

Lights converged, butterflies fluttered, as if in celebration...

"Butterfly?"

By the time Cain saw it, it was too late. Everyone present, including Nuwa, was pulled into the illusion, even if it was only for ten seconds.

A stunning moon descended upon the ark, emanating the aura of a demigod, yet her face was deathly pale, and her life force was rapidly diminishing. Ten seconds later, everyone awoke, and she too would perish.

At the cost of a demigod, everyone, including gods, was pulled into an illusion, all for these ten seconds!

"My lord, my mission is complete..." Haiyue held a ball of light in her hands, threw it at the red and blue creation, and perished.

"Hahahaha..." The ball of light burst into laughter, seemingly on the verge of victory.

"Roar!"

A dragon's roar shook the heavens and the earth; Cain reached the heart of the universe even faster than him.

"Do not……!"

An immense power surged through Cain's body, and various laws were etched into his mind, seemingly bursting his brain. At this moment, the virtual and real spaces came into play, and the vast天地 (heaven and earth) continuously absorbed this knowledge and helped Cain digest it.

Kain saw countless timelines and spaces. He saw the vast universe, the arrival of the Ark, the rise of the Tower of the Sun, the demon rebellion, the greenhouse being cleaved open, and the golden giant falling to the ground... Amidst the chaos, he tried to dispel the "clouds," but unintentionally stirred a golden fragment within these timelines, which drifted away to an unknown destination...

Soon, the demonic armor transformed into a silver-white suit of gold trim, and the ruler between his eyebrows became a giant sword radiating a mysterious purple light. Cain, with his flowing white hair, resembled a majestic prince.

He grabbed the ball of light, and Di Jun was instantly refined.

Cain surpasses the gods and suppresses all!

The crisis on the mainland has been resolved, and humanity and divinity coexist in this era, developing together.

In the songs of the world, Cain and his many family members traveled to many places around the world, living a carefree and joyful life.

The legend of the Armor King has never ceased. Kain's deeds have evolved into many more versions in later generations: the incarnation of the Azure Dragon, the wingless archangel, the lord of the underworld...

Cain's figure has already walked at the forefront of all things, to the end of the universe, smiling down on all worlds, waiting for humanity to catch up with this realm.

Finish.
