In the End of the World, I Become Infinitely Stronger by Picking up Attribute Balls

When Yu Tian traveled to the wasteland world, the beginning was a mess - his mother disappeared, his father died tragically, and he couldn't even get a full meal. He killed a gray rat, and the system spoke for the first time: "Congratulations to the host on the first kill, the speed attribute has been received." From then on, he only did one thing: kill mutant beasts and swallow attribute balls. Wind, fire, thunder, earth... He can fill up the board just by killing other people's extraordinary abilities that they have worked hard for a lifetime. Some people wanted to crush him with their bodies, but he smashed them to pieces with one punch; some people wanted to kill him with poison, but he drank the poison like water. "How much do you know?" Yu Tian smiled faintly: "Sorry, I know a little bit of everything." Starting from that squirrel, his counterattack has just begun.
