Let You Open a Zoo and You Build the Ancient Era?

Lin Fan, who originally planned to live a peaceful life, suddenly learned that his cheap father had a zoo that he wanted to inherit to him? ! Before Lin Fan could be happy, he discovered that this zoo was full of pitfalls! Dilapidated facilities, remote locations... And—— An extremely "awesome" name. You tell me, there are only two animals in the entire zoo? ! What? ! Inheriting a zoo and still have a debt of 3.6 Million to repay? ! When Lin Fan was frustrated, he unexpectedly awakened the [Atavism System]! Use animals as carriers to explore the origins and mysteries of living things! Bloodline returns to ancestors, genetic mutation! Sabre-toothed tiger, mammoth, Tyrannosaurus rex... On the blue star, a mysterious zoo was born! I heard that it has biological species that you know, and it also has species that you don't know! "Hey, hey! Tourists, stop feeding the baiji dolphins, feed the koi, they will almost become fat pigs!" "Tourists over there, please don't pull the wool on the mammoth!" "Hey! Sabre-toothed tiger, take care of your children and don't lie in the arms of tourists and act like a spoiled brat!" "Hey, my cat can do backflips. Do you want to come and take a look?" "What? Did I lie to you? I didn't lie. I have dinosaurs at home. Do you want to come and visit? Hello? Hello!" After hanging up the phone, Lin Fan looked helplessly at Jin Jianlayer who was doing a backflip beside him. There is also a ceratopsian lying on the ground. "Meow! Why, is she still unwilling to come?" After saying that, Jin Jianlayer turned a few more somersaults.
