In the anime, I become stronger by eating myself

After time travel, there is no system and no grandfather.

Just when Luo Zhen was ravaged by reality and felt helpless about life in another world, he saw other selves in an unknown space.

Good news, here comes the hang. The type that travels through many worlds at the same time can also gain the abilities of other worlds.

Bad news, what was obtained was too thorough, even the existence was taken away!

As for me, the golden finger that was supposed to be about a loving family turned out to be a story of survival where only one person can survive.
