Transmigrating at the Same Time, but It's a Dark Forest

Lin En transmigrated, and not just to one world, but to the Myriad Worlds.

The good news: every Lin En in every world had a unique, top-tier talent.

The bad news: all the Lin Ens shared the same cruel law of fate: [All Worlds Belong to Me]!

In the dark forest of the multiverse, killing yourself in another world meant taking all of their memories, fortune, and talents!

The Lin En who transmigrated to the Naruto world had the unique talent [Infinite Adaptation]!

Anything that couldn't kill him would ultimately grant him absolute resistance, endlessly boosting his physical attributes!

But before long, Lin En grew tired of this deadly competition, where they all tried to kill one another:

"I only get this much of a boost for killing another me? And to inherit their legacy, I have to fulfill the dead guy's wish before my attributes double?"

"This rate of growth is way too slow!"

Looking at the damage resistance that kept evolving on his body, Lin En had a crazy idea.

If attacks that don't kill me only make me stronger,

why kill them all?

Why not let all my other selves in every world grow unchecked, while creating an "ultimate nightmare" for the multiverse, one hell-bent on destroying everything?

Then the Lin Ens of other worlds, the superheroes, the world-ending villains, and the gods and demons of the Myriad Worlds would all be forced to join hands and unleash every last star-destroying weapon and forbidden law-level spell they had!

In the end, with the power of one man, he would take on the entire multiverse!
