You Mocked My Level One, but I Cast a Forbidden Spell and Changed Your Tune

[Fun-loving protagonist] + [genius growth] + [invincible protagonist] + [fast-paced] + [otherworldly classes]

Qin Mu returns to five years ago.

Beasts from beyond descend, endless in number.

Secret realms and abysses bare their fearsome claws.

Awakening a class and killing these beasts to raise its level is the only way to survive in the new world.

But only Qin Mu knows that in five years, the two worlds will collide, and a true cataclysm will descend, putting humanity in grave danger...

Back five years in the past, he decides to... lie low and build himself up first!

Because...

His golden finger from his previous life has returned with him, but he hasn't awakened it, leaving his level permanently stuck at “Level 1.” It won't unlock until the cataclysm arrives five years later...

He is met with mockery from his school, his classmates, and the base city...

Qin Mu laughs at their ignorance. Every time his experience bar fills up, he gains attribute points!

The world changes, and time passes.

The mockery vanishes, and one by one, they change their tune faster than pages turning...

Five years later, the true cataclysm descends.

They stare in a daze at the “Level 1” Qin Mu walking toward them alone:

“Bro, you can craft forbidden spells by hand at Level 1?!”

“How has this world evolved into something this insane?!”
