Chu Feng arrived in the Collapse Iron Universe by accident. Here, he was an egg, adopted by the natives of a planet, and lived a comfortable life until he hatched.

But the arrival of a Great Lord of Annihilation destroyed everything he possessed; the power of a casual strike could pierce through the stars.

Until, decades later, a giant dragon looked at the giant before it.

"Nanook, I've brought you destruction!"

Linnaeus, a transmigrator. He survived the Third War of Abundance, endured an arrow from the "Hunter," and served as a sea patrolman for twenty-eight years. Even his system had become incredibly strange. Linnaeus felt nothing could shock him anymore. What hadn't he seen? Until—he saw the white-haired paramecia that spawned in his room. Linnaeus fell silent. No. He had truly never seen anything like this before! Oh no! Had his room gone mad?!

Luo Guang traveled to a holographic world that blends the worldviews of DXD, Jujutsu Kaisen, Dark Rally, and Ghoul.

After his body became smaller, he didn't awaken his cheat code until he was twelve years old. As long as he practiced, he could continue to become stronger, and he was also given a portal function.

Of course, as a time traveler, he naturally couldn't be without a novice gift package. He started with the demon-slaying holy sword Esther, which could kill enemies and warm the bed.

Soon, Luo Guang became stronger, but he didn't go bald.

Baoyue Night Snack: "...Even if all the graduates were gathered together, they would not be his match."

Rias: "Rias, Rias, how can you be so stupid."

Shichito Sona: "Listen to me, thank you..."

Esther: "I was here first!"

Having traversed a dungeon, Evan arrived in Orario. He always felt that the dungeons he visited were somehow different from others. Corner attacks, mimics, and the classic three wolves and the Royal Archer duo—the sheer malice was unbearable. But it didn't matter. Evan: What doesn't kill me only makes me stronger!! And so, many years later… Black Dragon: Breaking the seal of Dragon Valley, he encountered Orario's number one fighter, whose stats were insanely high, a monster in strength, whom he couldn't defeat despite his best efforts. Damn it. Who raised this guy?! Dungeon: Yeah, who knows… (feeling guilty)

"I really only know a little bit!" Dairo Mochizou was on the verge of tears.

...

My name is Ooji Mochizou, and my dream is to live a peaceful life on campus and in daily life as a truly ordinary person.

But why am I always surrounded by these strange people?

"In the end, isn't it all because you broke the seal on the Holy Sword?!"

"Who knew there was a dragon inside!"

"...Wouldn't that mean we're doomed?!"

"Quickly summon Lucoa to save us!!"

Louise simply shouted.

"Damn it, I already summoned her, but it seems I teleported Lucoa to the Demon Realm!"

"You unreliable idiot!!"

Regarding the issue of the unconventional world he transmigrated to, Hinata Gen said he didn't care at all. This was a paradise, where all the action and passion could go to hell; it was all about slow-burning daily life and collecting girls.
