My sister is Luna

The endless yellow sand stretches to the horizon, the scorching sun hangs high in the sky all day, evaporating the moisture from the body, and they must always be on guard against the demons and bandits who may attack from time to time. This is the monotonous and boring daily life of the soldiers stationed at the Great Wall. Perhaps only a little entertainment during their rest can add some joy to their lives.

But they never dared to relax, because the price of slackness was life. The demons and bandits wouldn't consider your feelings or whether you had family members you missed.

"It is said that floating clouds can obscure the sun, and the sight of Chang'an makes people sad." The tall Su Lie stood on the Great Wall, looking at the vast desert, and couldn't help but sigh.

"General Su Lie, are you homesick?" Cain, who was standing on the other side, withdrew his gaze from the distance.

Cain and Su Lie got along quite well, perhaps because they were both strangers in a foreign land and felt a sense of kinship.

"Just reminiscing about the past," Su Lie said with a smile.

"However, Deputy General Su Lie is quite talented in writing."

"I only learned a little from a friend of mine. His poetry is absolutely superb, far superior to mine. He's also a man of both literary and martial talents."

"Also, there's no need to be so formal in calling me Deputy General. Just call me Su Lie. We're all comrades-in-arms, why bother with such a hierarchy?"

"Work is one thing, but I'm bound to be gossiped about and reported on by some petty people. I don't want to be sitting at home and suddenly get into trouble," Cain said, pursing his lips.

There was a military supervisor sent from Chang'an on the Great Wall. Seeing those guys so arrogant, acting like "I'm from Chang'an, and I'm proud of it," Cain was annoyed. But he couldn't do anything about it. If he beat him, he definitely wouldn't be able to stay on the Great Wall. His investigation of the Great Wall wasn't over yet. If he didn't beat him, he couldn't swallow his anger.

"Alright then, whatever you say. There's nothing we can do about it; that's how the court is." Su Lie knew the reason behind it all and didn't want to say anything more. He turned to look at the unchanging yellow landscape.

“Speaking of which, apart from the recent harassment by bandits, it seems that the demon seeds haven’t come back. It’s really strange. There used to be several demon seeds coming almost every day, but they haven’t come these days. Do demon seeds take a vacation? It’s like they’ve all disappeared.” Cain said, thinking about the recent events and looking at the desert landscape.

“Yes, it is indeed strange. What could possibly make these demonic creatures stop in their tracks?” Su Lie said, frowning.

"I have a bad feeling about this."

“Based on past experience, these demons are targeting the Great Wall and will come in groups to harass and attack it. There is clearly someone directing them. Could it be that the mastermind is brewing something or gathering more demons, wanting to break through the Great Wall in one fell swoop?” Cain speculated.

“What you said makes sense. The outpost has reported that many demons are gathering in the direction of Golden Court City. Judging from their unusual behavior, it seems that a tough battle is about to begin. Although we don’t know what they are thinking, let the warriors prepare.” Su Lie stroked his chin and nodded, deciding to tell everyone this decision that night.

"News has come from the King's Canyon that a dragon-type demon has flown to the Cloud Desert. Judging from its appearance, it's a Tyrant, which might cause trouble. Hopefully, it's not in the demon race." Su Lie thought of another piece of news and couldn't help but feel worried.

"Gah, gah, gah..."

Suddenly, a large flock of birds flew out from the horizon, forming a huge multicolored cloud, flying over the Great Wall. Watching their hurried appearance, one could sense a sense of fear. They seemed to be afraid and trying to avoid something. Animals are generally able to keenly sense danger and flee, which also served as a warning to the Great Wall guards.

"Come with me, Cain." Seeing this scene, Su Lie, looking rather grim, led Cain down the Great Wall to his room.

He took out a special piece of paper, wrote and drew on it, and then handed it to Cain, saying seriously:

"This is a notification order. Take it and give it to the messenger, who will notify the people in all villages and towns to evacuate. Such a large number of birds fleeing indicates that the demons are planning something big. They will definitely come in a massive wave in a few days. They can't wait any longer and are preparing to start the war ahead of schedule."

Upon receiving the order, Cain was about to leave when he turned around and saw a strangely shaped bow hanging on the wall. The upper and lower bow plates were not as slender as those of ordinary bows and arrows, but rather wider, like wings. Moreover, there was no bowstring, and the color was gray and dull, as if it were a bow made of stone.

Cain wouldn't have asked much normally, but he felt the bow looked familiar, so he stopped and asked, "Deputy General Su Lie, what is that bow? It has such a strange shape."

“Riyuan, according to legend, Hou Yi shot down nine suns with nine bows, and Riyuan was one of those bows. However, whether it is true or not is no longer verifiable, but its history is indeed several thousand years old. It was already here when the Great Wall Guard was established, and it has been kept in the collection ever since. Don’t be fooled by its small size; it is actually very heavy, and no one knows how to use it,” Su Lie said.

Cain immediately understood, thanked him, and muttered to himself as he walked out the door:

"I see. No wonder it looked so familiar. It's the Sun Abyss equipment. Hou Yi used it. He's probably still buried in the ground now. Strange, how come his bow is on the Great Wall?"

Judging from the appearance, the Sun Abyss is a divine artifact that destroyed even a miracle like the Tower of the Sun. A weapon created by the gods is indeed different. I think even a powerful being at the King Realm couldn't withstand its full-force attack. But the color is a bit off. I remember it wasn't gray. Is it rusted and faded? Cain pondered this question as he walked.

"It has a history of thousands of years. Could it be that someone took Hou Yi's bow to the Great Wall after he died?"

Cain shook his head to stop thinking about it, and after completing the task Su Lie had given him, he stood on the Great Wall to keep watch.

“Kain, I heard from Su Lie that this attack by those demons might be an unprecedentedly fierce battle. I hope you can get yourself ready and fight alongside me. Not only have the birds in the sky sensed something and flown away, but some small animals on the ground have also begun to feel something is wrong and are migrating in large numbers. This is something that has never happened in previous wars.”

At this moment, Mulan appeared beside Kaiyin, her face full of solemnity: "Also, that tyrant might be among them, which will be much more troublesome than we imagined."

"Don't worry, I'm not bragging, no one can withstand a single strike from my Demon Armor." Cain chuckled and patted Mulan on the shoulder.

"They are demons, not people. I know your demon armor is strong, but don't be careless. There might be a lot of demons this time." Mulan laughed and relaxed, patting Cain on the shoulder, but her words were full of concern and advice.

"I will. We'll fight side by side then. What's there to be afraid of? The Great Wall has never fallen before, and it won't fall now either," Cain said confidently.

“You’re right!” Li Xin walked out with his sword on his back and his arms crossed, leaning against the city wall.

"Hehe, and there's this cat too!" Shen Mengxi jumped out from somewhere.

"The Great Wall has stood for so long, and it has seen all kinds of difficulties. We will eventually be victorious." Su Lie carried a large pillar and walked up the Great Wall.

"Because we are the Great Wall Guards, we live and die together, protecting our homeland!" Mulan smiled broadly as she looked at Cain.

"That's right, we'll live and die together to protect our country!" A large group of soldiers shouted behind Su Lie.

The Great Wall Guards were mostly composed of good families from the border regions. They joined the army to protect their villages or families. Living on the border, they understood the meaning of defense better. Su Lie also taught them principles, so they knew why they were fighting. An army that knows the meaning of fighting is definitely a powerful and tenacious army!

There was no fear on any of their faces. On the contrary, the corners of their mouths turned up, revealing a faint smile. It was not a forced smile, but a calm and composed smile from the bottom of their hearts, as if they were facing not a life-or-death war, but just an ordinary challenge.

Their eyes were firm and bright, revealing a resolute and fearless spirit in the face of death. Their gaze was like a burning flame, intense and powerful, seemingly able to penetrate all the difficulties and obstacles in front of them and reach the other side of victory.

"Everyone……"

Cain was deeply moved. He could feel the genuine emotion in them. They trusted each other and were comrades who had entrusted their backs to him. It was a profound bond. Cain clenched his fists and his gaze became firm.

A bond called the Great Wall tightly connects everyone together.

I will cherish this camaraderie, and I will fight to the very end! I will never let them down!

Cain made up his mind.
