Beast Control Evolution? It's Better to Mutate One of the Beasts

In this world, powerful top beast masters can destroy mountains and seas, regenerate broken limbs, travel thousands of miles in a day... And so on. Most of the things that are unthinkable on the blue planet are not problems here. In this world, everyone from white clouds to rocks has the possibility to become a beast master, and the humans who sign contracts with them are called beast masters. Lin Feng, who was a small social beast in his previous life, traveled through time and relied on the system to embark on a different path of beast control, possessing a powerful beast control that no one else had. Beast control evolution? What is that? According to me, it's better to mutate a hair than to control a beast. Who said that poor people rely on mutation? Who said that, if you come out and challenge me, your family won't even recognize you when I beat you.
