Jun Qing, who transmigrated from another era, has experienced countless years and possesses many identities. He inexplicably arrives in the pre-collapsed civilization of the Honkai world with the Gates of Hell and the Eight Great Demons.

After the end, Jun Qing became the captain again. He changed the regretful fate of all worlds. In the long time he had traveled, this was perhaps just an insignificant moment in his journey to the myriad worlds. After the end of the previous civilization, he awoke and traveled with Yuexia to the world of Akame ga Kill! and then to the world of Genshin Impact...

Ten thousand years ago, I witnessed the destruction of a civilization, the shattering of memories, and the arrival of an end. At that time, I was powerless to stop it.

Fifty thousand years ago, I felt a familiar civilization, familiar things, and familiar people, but the memories that traveled through time were not in my mind. I watched as the end destroyed civilization once again, but I suddenly regretted it.

And now, the power to save everything, all the memories of the past, are within me. This time, I don't want to lose them again, nor can I lose them. I will grant your wishes and make this world beautiful again.

Sing joyfully, all things in the world, to welcome the death of your god, who will bring boundless beauty to this world. What, "you" refuse? No, no, no, you have no reason to refuse any of this, nor is there any room for negotiation.

Thirty years ago, the Seventeenth Joint Campus was destroyed by an unknown force, turning the once prosperous academy into a desolate ruin. Our forefathers fought desperately during the catastrophe, sacrificing their lives to give their descendants a chance to survive. However, the survivors still wander among the ruins, lost, helpless, and uncertain of the future.

Just as despair was spreading, a firm voice rang out:

"Reconstruction, revival, revenge."

Guided by this brief yet powerful message, the students of Campus 17 wiped away their tears and rose again. They rebuilt their homes from the ruins, unearthing buried scientific discoveries from the depths of the rubble, etching the tragedy into their hearts and transforming past pain into motivation for progress. Beneath the wasteland lies not only a shattered civilization, but also revelations powerful enough to change the future.

Thirty years later, when a similar disaster struck another school known as "Children's Eden," the students of the Seventeenth Campus resolutely raised the blade of revenge. They were no longer helpless survivors, but fighters who had overcome the shadow of death. With thirty years of accumulated experience and the strength forged from the ruins, they would safeguard hope and reverse their fate.

"The past belongs to history, but we remember it."

"What is now ruins, we will rebuild."

"The future belongs to hope, and we create it."
