Reborn, but There Are Billions of Problems

Good news, reborn. Bad news, rebirth went wrong. At the end of the world, various disasters and mutated monsters have been rampant on the earth for thirty years, and human civilization has regressed to the Iron Age. It wasn't until someone mastered the method of stably utilizing the mutation and evolution of the Mist that humans were able to regain all the lost land, regain the technological achievements of their predecessors, and even physically walk into the stars in just twenty years. Lin Yuxi, as a veteran who survived the old thirty years and a rising star in the new twenty years, followed the strong humans into space, but found that there were countless weird and powerful creatures around the earth, watching with eager eyes! In front of such a monster, whether it is advanced technology or strong human beings, they are like a piece of tofu, breaking at the touch of a touch. Now that he was reborn, Lin Yuxi decided to change this ending, but for some reason, he was reborn as a weak little girl with congenital heart disease! Why do you occupy my original strong body? In my world, you can awaken key abilities! Forget it, with the knowledge behind it, humans will definitely be able to overcome the fog in advance, but why can't this body awaken its superpowers? Forget it, with my wisdom and my own superpower talent, it shouldn't be a big problem. But when Lin Yuxi saw "him" arriving at the door of his house, his heart almost stopped and he left immediately.
