Abnormal Beast Taming

This book is also known as The Beast Tamer Is Absurdly Fit and How a Beast Tamer Made It Through the Gate.

After waking up one day, Zhang Chi, who had picked up all kinds of strange skills, transmigrates to another world, where his pet cat becomes his first contracted beast. In this world, Zhang Chi gets to experience all sorts of bizarre things.

Is there anything bad about it? Maybe just that the other world doesn't have smartphones.
