My sister is Luna

night.

Cain stood on the Great Wall. After the lively welcoming party, some people went to sleep, while others remained on guard. However, he couldn't sleep, so he volunteered to guard the Great Wall. Su Lie readily agreed and had a very good impression of Cain.

Gazing at the bright moon and stars hanging high in the sky, Cain's thoughts began to drift away.

It's been almost half a year since I left home. I wonder how Luna is doing, and how my parents are doing. Especially Luna, I wonder if she has taken my words to heart. It's true that it's more meaningful to eat the cabbage you grow yourself... Wait, why am I having this thought?

Cain was filled with doubt. Had he been influenced by his family? That wretched family.

Shaking his head to stop thinking about these things, Cain looked up at the moon. In Cain's eyes, the moon seemed to become Luna, then his parents, and then Milady. His longing kept welling up involuntarily. After being away for half a year, he now understood what homesickness was.

Since Cain obtained the virtual space, he has found that he can more effectively resist the urge to kill. His use of golden energy has improved significantly. He has more mental space, but physically, he still feels a great threat from the blue energy, it just hasn't arrived yet. Besides, he promised Mulan that he would guard the Great Wall, and starting from the miracle is also a way to do so. Perhaps the Great Wall, as a miracle, might have some unexpected ways to help him.

Cain turned his head and suddenly noticed that not far from him, a black-haired youth was also gazing at the moon, his dark eyes filled with longing, and an aura of loneliness surrounded him.

“Chang’an, my hometown…” Li Xin looked at the desolate moon in the sky, and his homesickness kept welling up, and childhood memories kept replaying in his mind.

But the prosperity of Chang'an was no longer relevant to him, and resentment grew in his heart. He murmured to himself:

"I will not let Chang'an forget me."

The lofty ambition to achieve great things and the anger and hatred of being abandoned on the border are intertwined in the heart of the once noble and admired son of the deposed crown prince, who is now destitute and ignored.

"Hey, brother, let's get acquainted. My name is Cain." Cain walked over to Li Xin. He saw that this black-haired young man had an extraordinary temperament and wanted to make his acquaintance. He was also looking for someone to chat with to relieve his loneliness at night.

"Li Xin." Li Xin pulled himself together, glanced coldly at Cain, and then turned his face away to face the vast darkness.

A flicker of surprise crossed Cain's eyes, but he quickly regained his composure.

“I see you’re gazing at the moon too. Are you thinking of your home? I miss mine too. Although it’s just the four of us in a small house, we’re very happy. My parents are loving, and my little sister is adorable. I cherish and love her very much.” Cain said with a smile, his gaze fixed on the distance, as if he had traveled through time and space to see Luna and her parents…

"If you cherish it so much, why did you leave and come to the Great Wall?" Li Xin envied Cain for having such a happy family, but when he thought about Cain joining the Great Wall Guard, he couldn't help but wonder.

"Sigh, I'm seriously ill and don't want to be a burden on them," Cain said with a sigh.

"Maybe I'll be able to go back to them if I'm cured, or maybe I won't be cured."

"I'm sorry," Li Xin replied apologetically, after a moment of surprise.

"It's alright. What about you? Where do you live?" Cain chuckled.

“…In Chang’an,” Li Xin said after a moment of silence.

"Chang'an? I've heard merchants say that Chang'an is beautiful and prosperous, with skyscrapers everywhere. Is that true?"

"More beautiful and more prosperous than they described." Li Xin seemed to be reminded of the past by Cain's words, and said wistfully, "Merchants from the west came every day, and at night the city was ablaze with lights, with magnificent palaces and pavilions. The people of Chang'an were proud of it..."

What you said makes me really want to go.

"I'll take you there sometime." Li Xin's lips curled up slightly. The two, who were also homesick, found common ground. Young people always hope to have companions.

"Okay, Li Xin."

……

After chatting with Li Xin all night on the Great Wall, Cain was mesmerized by the magnificent desert sunrise.

As I watched, I suddenly felt the wind pick up, and sandstorms rose up, slowly gathering and flying, disturbing my eyes. A storm began to form, and a strange sandstorm arrived.

At this moment, the piercing alarm began to sound, and all the soldiers of the Great Wall Guard quickly assembled on the Great Wall.

Cain stood at the back of the group listening to Su Lie's instructions. Mulan stood quietly beside Cain, her helmet covering her striking red hair, and no one noticed her.

“A new demonic species has attacked this time, called the Eye of Annihilation. This strange sandstorm was created by it. The sandstorm will obscure your vision, so you need to be careful,” Su Lie said solemnly.

Then he hoisted his large pillar onto his shoulder: "Now it's time to fight back! Archers, stand by on the city walls."

After speaking, he took the lead and walked out of the Great Wall, staring intently at the hundreds of bright, scarlet eyes in the wind and sand.

"Archers, shoot!"

Arrows rained down, and the demons hidden in the sandstorm either retreated or charged forward. After a volley of fire, the archers waited on the city wall.

Su Lie shouted, "Brothers, follow me! Don't go more than a hundred meters past the Great Wall, and make it back alive!"

The battle was about to break out, and all sorts of demonic creatures leaped out of the sandstorm. The Great Wall Guards fought them head-on, while Shen Mengxi threw cat-shaped cannonballs from the Great Wall to provide support and cover for them.

Cain walked through the dusty battlefield, his blade flashing, and a demon died. Suddenly, he saw Mulan running into the distance and quickly followed.

"Mulan, why are you running so far? Didn't Su Lie say we can't go more than a hundred meters? If we go too far, we'll get lost in the storm. And when are you coming to get your greatsword?" Cain said, pulling Mulan aside.

"Sister is going to find the Eye of Annihilation. It's the instigator of this war. Only after we deal with it will the sandstorm stop. Sword will go after we're done with this," Mulan said.

"To catch the thief, catch the king first? Good idea, I'll go with you." Cain's eyes lit up, and he quickly followed Mulan toward the center of the sandstorm.

……

"Hahahaha, Great Wall Guards, today is your death day. Hmph, that guy said to be careful in everything, but I haven't seen how powerful they are. Just slowly get lost in the yellow sand."

At the heart of the sandstorm, a gigantic, yellow, humanoid demon laughed wildly.

At this moment, its keen intuition sensed danger, which strongly stimulated its brain. Trusting the intuition honed through years of life and death, it turned its neck in response to its body's reaction, and a sharp sword aura brushed past its shoulder.

"Who goes there!" the Eye of Annihilation roared furiously, the sandstorm surrounding it intensifying.

"What kind of hero is a treacherous villain who sneaks around? If you've got the guts, come out in the open!" His scarlet eyes gleamed as he stared intently at his surroundings.

"How dare you bark like that, hiding in the shadows and creating sandstorms to launch sneak attacks?" A cold voice came from the sandstorm.

Li Xin stepped out carrying his sword. The Eye of Annihilation was protected by sandstorms, so it was only a matter of time before it discovered him. It was better to take the initiative and attack.

From the very beginning, Li Xin was determined to catch the mastermind behind the sandstorm in order to gain merit and be promoted.

"Just you alone? That's incredibly arrogant! You're facing my Eye of Annihilation!" The Eye of Annihilation roared, whipping up layers of sand and dust as it attacked Li Xin.

Li Xin raised his sword to block, but the immense force forced him to retreat, leaving two long marks in his wake.

The Eye of Annihilation slammed another heavy punch at Li Xin, leaving him unable to retaliate. The hard blade of his sword trembled violently from the impact.

Li Xin coughed up a mouthful of blood. He used the broad back of his sword to deflect the Eye of Annihilation, raised his sword high and slashed at it. At the same time, his sword energy burst forth, breaking through its defense and cutting a deep wound on its body. Then, he stepped on its body and jumped backward, moving his feet to dodge its counterattack.

This repeated process left several wounds on the Eye of Annihilation.

But when he attacked again, hoping to kill Li Xin in one blow and make a quick victory, the giant hand that suddenly erupted from the Eye of Annihilation grabbed him with lightning speed.

"I've already seen through your attacks. The previous attacks were just tests. You do have some strength, but you're still too eager for quick success." The Eye of Annihilation looked at Li Xin with mockery.
