Lassen, a young man who has failed at everything in his life, has had enough. Disillusioned with the world, he decides to end it all. But instead of dying, he wakes up in a parallel world, armed with a strange system that can accomplish anything he desires. Trapped in his room, reading novels and savoring every page, he has no intention of participating in the fast-paced world outside.Yet, despite his desire for peace, the world changes every time he makes an appearance. Everyone treats him like a genius, a being capable of disrupting the very fabric of reality, without lifting a finger. A powerful system, a new life, and a world that adapts to him: why complicate things when you can have everything without effort?The Genius System tells the story of a man who, although having everything to change the world, prefers to watch it evolve from the comfort of his room, through the pages of his books.

[Contains explicit content, violence, and mature themes]Infinite Breaker Online descended on Earth, forcing humanity to play 12 hours daily and initiating events. Axir Grimspire rises to become one of the top players of Earth, one of the ten sovereigns, after five years of brutal warfare. He has everything—power, a guild, a girlfriend he adores, and trusted friends.Or so he thought.Betrayed by those closest to him, Axir learns the horrifying truth: his girlfriend and friends used him as a tool, his sister was murdered by the men he called brothers, and now they're casting him into Godfall Abyss—a forbidden zone where the player's death is permanent if they die there. No respawn.But as Axir dies, he triggers an Ultra Unique Event in the forbidden zone: the Abyss of Desire, which grants him one wish. He chooses to return to one week before the game's beta launch with memories intact.But his wish has consequences. Triggering the Abyss of Desire would connect the Abyss Realm to all planets connected to the game's server, a higher dimension world called World of Belkris, and gods from various mythologies would manifest, offering humanity divine boons upon fulfilling requirements. On top of that, World of Belkris is 50% different in everything, from the geography of the Belkris to the fickle luck that changes constantly to develop things differently from what Axir once knew.Armed with five years of knowledge and burning for vengeance, Axir begins his second run in a drastically altered game—determined to make his tools of his betrayers rather than being used by them and reach the top.--Discord: BjeQvXzZBB

The world I reincarnated into was a world that enabled you to use magic after having read a Grimoire.

And the Grimoire’s contents areーー you wouldn’t believe it- it’s 「Manga」.

This world’s people would take around a year to read a single Grimoire (Manga)

While for me, it would not take an hour, as it was「Manga」

Interpreting and understanding all kinds of Grimoires, the 6 year old me who became the World’s Strongest Master Mage, welcomed brides that were also 6 years old, and started living a carefree life……!!
