Yuuji Sakai, the usually vacant and somewhat weak protagonist, lives an ordinary life until the sudden appearance of a monster disrupts his ordinary life. Under the setting sun, Yuuji is suddenly attacked by an alien monster that transforms human "existence" into spiritual fire and then devours it.

At this time, a girl who called herself "Flame-haired and Burning-eyed Slayer" appeared and rescued Yuuji from the monster's mouth. Yuuji Sakai named her Shana based on the name of her large sword.

She told Yuji that his life was about to end - it turned out that outside this world, there was another world called the "Red World". In order to realize their ambitions, the people there took away the world's original power, the "power of existence", from humans one after another, and Yuji was one of the victims.

After the Crimson Apostle took away the "Power of Existence",...

The world has restarted, but you lost your memories. Will you become the protagonist of the story?

————

All living beings on the Tianyuan Continent possess three souls, from which three cultivation paths have emerged: body refinement, qi refinement, and soul refinement.

Xu Lin, who died and traveled through time, did not have three souls and seven spirits. He had to let the ghost lady Mochi reside in his body, pretending to be his soul, thus being resurrected as a half-human, half-spirit.

His otherworldly adventures then veered towards an absurd and bizarre style.

Xie Si, a little girl who was bought to be buried with her husband in a ghost marriage and is now in utter despair?

A sickly, delusional childhood friend who feeds false memories to her feigned amnesia and is full of lies?

A foster father who searches far and wide for books from Earth and develops religion, economy, and technology in another world?

Laplace the fairy, an otherworldly escapee who impersonates a system?

Xue Miaomiao, a catgirl who works as a hunter from another world in a brothel?

A half-human, half-demon daughter from the future, living in mourning?

Even more so, there are those who want to refine themselves into spirits and stay with their past life lovers for life?

...

While gradually repairing his battered life through adventure, Xu Lin uncovers the secrets of the Tianyuan Continent and its immortals and gods.

Shocking! The Tianyuan Continent is flat! There's another world on the other side!

They were all fooled by Him! The Three Lives Stone was actually fossilized dung from a real dragon!

Is this what they're doing, restarting the world?

...

This world has long been riddled with holes by the local immortals and gods who are obsessed with entertainment and the foreign demons who have distorted the laws. Should Xu Lin, who knows everything, save this world that is on the verge of collapse?

Is it that what they can do, I cannot?

[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."

What?! You're the creator god! Grant me three wishes to be reborn?! From that moment on, Dongfang Huanyu transmigrated into the world of Yuan Zun. He embarked on a path of unparalleled power, the kind where there's no turning back. Yao Yao: "Little Huanyu, this outfit is nice, why don't you try it on?" Wu Yao: "Yes, yes, you should try it on." Dongfang Huanyu: "No, I refuse, I won't wear women's clothing." "Huh?!!!!" Dongfang Huanyu: "Uh... then I'll wear it just once, just once."...

He unexpectedly finds himself transported to the world of Fairy Tail, only to discover he possesses the ability to summon Digimon. In this world of magicians, how will he and his Digimon partners write a new legend for Fairy Tail? When the magic of Fairy Tail clashes with the Ultimate Digimon, an adventure spanning dimensions begins.
