[Slightly hardcore] + [A huge number of self-created academies and students] + [With both angst and sweet moments] + [Daily life/battle]...

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."

Lin Mo, a socially awkward gamer, transmigrates to a peaceful world that hasn't collapsed and becomes an ordinary freshman at St. Freya Academy. He intends to live a quiet and uneventful life, but the world's top gaming competition, "Chapter of Legacy," opens just in time. Three giants join forces, offering a bounty to find the "civilizational legacy" that can define the next era.

While others were still brainstorming gameplay ideas, Lin Mo pulled out the Honkai Impact 3rd project proposal: "Since you've all forgotten, I'll make this world remember again—"

From then on, the art style completely went astray: Top student Mei was revising the script while shedding tears: "This plot... won't the players send me death threats?" Wendy was caught drawing Honkai Beasts by the dean of students: "Your aesthetic sense... is quite shocking!" Bronya worked all night optimizing the physics engine: "The sense of impact must be on par with a real battlefield!"

The demo version caused an uproar online: "This swordsmanship and this performance? You call this a student's assignment?!" "I couldn't stop crying when I saw Himeko-sensei?!" "Urgent request! How do I get to the part where the Honkai Beasts attack the school building? The immersion is too strong!"

What Lin Mo didn't expect was that Otto, the president of the Destiny Group, personally sent a cooperation invitation, the genius scientist from Anti-Entropy came to his door overnight, and even the mysterious World Serpent Group began to pay attention to his movements...

Standing on the stage of the global finals, Lin Mo smiled at countless cameras:

"This is not just a game; it's a world civilization."

"And now, it is your turn to take up the torch of this civilization."
