Passive Beast Master

This is a different world where beast control is the mainstream. Animals, plants, elements, undead, machines... And even swords can be used as pet beasts, and the humans who contract, train, and control them are collectively called beast masters! Mo Bai came through time travel, bringing with him a powerful talent that gave him passive skills to control beasts. But why can my contract only be signed passively? Mo Bai is looking for a strange beast with a unique personality. They are lonely, weird, and long for recognition. Later, people were saying, Mo Bai? That's a weirdo and a prodigy.
