Biologist in the World of Animal Control

A biological scumbag who traveled through time 3,000 times and came to the world of beast control. A biology enthusiast whose actual age is over 30,000 years old but whose mental age is still 13 years old. A big villain system that lost its dream because of 3,000 time travels. The biologist of the beast-controlling world is here. Behind him, the giant dragon became a dragon, thousands of birds soared, wild beasts galloped, and hundreds of insects chirped. Flying in the sky, swimming in the sea, running on the earth, above all things. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
