In this world where mythical beasts are rare, Qin Ming's spirit beast... is not right!
Initially, he was just an ordinary person who could travel between two worlds.
But the grass turtles that you can eat at home have a whole world inside their bellies.
He traversed between the two worlds with extraordinary power.
A brand new spirit beast was born from his hands...
He also has a unique skill that always turns the rotten into the miraculous!
