MTL - After Two Lifetimes I Was Reborn Back Inside A Book - Chapter 4 Wear it back on the fourth day

On just another normal Monday, the world changed. The universe had reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A world where power is the only thing that one can truly rely on.

Jake, a seemingly average office worker, finds himself thrust into this new world. Into a tutorial filled with dangers and opportunities. In a world that should breed fear and concern, an environment that makes his fellow coworkers falter, Jake instead finds himself thriving.

Perhaps… Jake was born for this kind of world, to begin with.
