My sister is Luna

Xuan Yong was suddenly caught in a war, and Kai fell into the abyss and disappeared. His whereabouts are unknown. He will be remembered forever by the people of Xuan Yong, who will do their utmost to search for him.

This is an official announcement from Xuan Yong, and Jixia Academy has also confirmed it.

“We will definitely find you, teacher…” Jingyao and her brother joined the search and rescue mission. Although Bian Que was not optimistic about Cain’s chances of survival in Hell, the siblings were determined to find Cain.

Upon hearing this news, Milady, who was at Jixia Academy, felt her vision go black and nearly fainted. She suppressed her panic and confusion and calmed down.

"How could this be..." Milady stopped repairing the machinery, muttering to herself. Everything had happened so suddenly.

No one expected that a war would break out in Xuan Yong like this, and no one expected that someone as powerful as Cain would be left to fend for himself in this war.

Suddenly losing someone important to you feels like your heart is being torn apart; it hurts so much.

"I should have gone with him back then... Cain..."

Milady leaned back in her chair, covered her eyes, and a few tears streamed from between her fingers. Her thin body looked so lonely and helpless.

Tears are a sign of weakness, but she couldn't stop them no matter what she did.

This was the first time she, in her high position, had experienced this feeling, and it was indescribable.

"No... he's just missing. He should still be alive, he's just temporarily gone..."

Milady still held a sliver of hope.

He must be hiding somewhere; he must still be alive!

Milady told herself this.

After a long while, once she regained her composure, Milady couldn't wait to go to Xuan Yong to search for Cain's whereabouts.

However, this is just a matter of facing reality a little later.

Milady searched the entire Xuan Yong region but found nothing. Even after mobilizing all her mechanical servants and leaving no corner unchecked, she only found traces of her on the battlefield.

There were traces of the unique energy he used when he used his magic armor around a crack.

All the energy flows pointed to him rushing into the crack.

Digging into the crack revealed nothing; digging dozens of meters deep yielded no trace, only damp yellow soil.

It's not simply entering a certain underground place, but entering a certain place from a spatial level. But what is in that unknown place?

According to information gathered by the mechanical servants, the monsters that triggered the Xuan Yong War emerged from that rift, including a being at the King Realm. He was dragged into the rift by the monster, and since the monster did not die, what are the chances of him surviving?

She had to face the fact that defeating a king was not an easy task. Although Cain was strong, he was only invincible within the same realm, and the world inside the rift was the domain of those monsters.

No matter how much I think about it or how I deduce the possibilities, there is only one answer—Cain is doomed.

Her emotions refused to believe it, but reason told her it was true. Milady was devastated, her heart empty and void, unable to grasp anything.

"Boom boom——"

Dark clouds rolled in, thunder roared, and emotions were brewing.

The weather has been gloomy these past few days, just like her mood.

Milady gripped her cane tightly, her eyes glazed over as she stared at the pit that had been dug dozens of meters deep. All the facts were laid bare before her, silently telling her the truth.

"Shuisha——"

The torrential rain washed away the bloody traces of the past battlefield.

The rain soaked her hair, the strong wind tore it into a mess, and her wet clothes clung to her thin body.

Mechanical servants surrounded her, relentlessly and loyally enduring wind and rain.

The rain was drizzling down, and the gloomy weather obscured her expression.

The tears streaming down her fair cheeks were either rain or tears.

This "baptism" fueled her burning passion even more; she was determined to find Cain!

If he's alive, I want to see him. If he's dead, I want to see his body!

……

Jixia Academy.

The champion of the Guixu Dream Performance Competition, which had just been held not long ago, suddenly disappeared, causing an uproar among the students and sparking widespread discussion.

"That Cain just died like that? What kind of war is this that broke out in Xuanyong?!" someone exclaimed in surprise.

"What a pity to lose such a good teacher," someone sighed.

"War inevitably results in casualties; peace truly is hard-won," someone remarked.

"Hmph, it's foolish for a foreigner to fight for another country. He could have left, but he insisted on staying. He deserves to die!" someone scoffed.

"That's right, Cain got cocky. He thought he could resolve the war by relying on his strength, and that Xuan Yong would be grateful to him and have people sing his praises, making it easier for him to achieve his own interests. But he never expected this, never expected this..." someone echoed.

"How could you do this? Doesn't this demonstrate Cain's selflessness? He helps people equally, regardless of nationality, social status, or wealth. Does he just stand by and watch the people of Xuanyong suffer casualties? Aren't people from other countries human beings?" someone protested.

"You're still thinking too idealistically. Prioritizing one's own people over foreigners is just adding fuel to the fire if the two countries are at war. But if the entire continent is unified, then all people will be equal and considered one of our own, and he will indeed be worthy of praise. However, no one has that ability right now, and no one will in the future."

"That's a ridiculous statement! These are two completely different things!"

"I think……"

People are discussing it, and there's been a lot of controversy. They're saying Cain is good, and they're saying Cain is bad.

Kain provided Xuan Yong with crucial assistance, revealing a different side of him to the public.

People's joys and sorrows are not shared. They don't care about Cain; they are using this incident to discuss themselves, others, society, and the world...

Some are happy, some are sad; right and wrong, good and bad, are always relative and intertwined in the debate.

This is the contradiction of humanity: bestiality versus humanity, order versus chaos, evil versus good... countless factors constitute human beings.

The only people who truly care about Cain are those who are close to him.

“Brother Cain…” Xi Shi was incredulous upon hearing this devastating news. She covered her face and wept. This sudden death was like a sharp knife piercing her heart.

The image of the person she longed for suddenly vanished, inevitably causing sadness, just like a first love who left before she could even confess her feelings. Xi Shi was not happy to experience this feeling for the first time.

Since the dead cannot be brought back to life, she can only cherish the people in front of her even more.

"War inevitably results in death, but at least Cain is remembered by history, and Xuan Yong even erected a monument to praise his achievements. His life was worthwhile." Having experienced all this, Zhong Wuyan was quite open-minded and patted Xi Shi on the shoulder to comfort her.

"Alas, let us accept this loss. No one expected that Xuan Yong would suddenly break out into war. What a pity for Cain..." Lian Po lowered his eyes and sighed.

"Damn it..." After a moment of silence, Zhong Wuyan cursed under her breath, still holding back her anger.

She knew that Cain's sacrifice was right, correct. He was not harmed by villains and forced to die, but it was the right ending. Death is not terrible; everyone will die.

But who wouldn't react when a friend leaves, and want to vent their frustration?

The two felt more regret and helplessness than anything else.

Yang Yuhuan sat quietly to the side, lost in thought.

Where should I go?

Yang Yuhuan was lost, and Cain was a beacon of light for her.

But the person was gone, and she was lost. She could only go back to report to the Empress.

On that same day, everyone discovered that Milady had left without saying goodbye.

With Cain missing, there's no point in him staying at Jixia Academy anymore.

She would do everything she could to find clues and to find Cain.

……

Meanwhile, on the Tang Dynasty side...

Wu Zetian was furious. What difference was there between disappearing on the battlefield and being dead? How could someone just go to see a doctor and be gone?

But she could only sigh helplessly, her heart aching, but she couldn't act impulsively, because she was the ruler of a country. Cain hadn't done anything wrong, nor had Xuan Yong. She wasn't alone; she carried the weight of the nation on her shoulders. She could only do her best to secure benefits for Cain, give Xuan Yong a good beating, and leave Cain with a good reputation so that he would be remembered for generations.
