Be A Global Beast Master By System Bugs

In a world ravaged by fiend beasts and spatial rifts, humans fight back using "Soul Contracts" to tame these creatures, turning them into protective spirit animals. Amidst this chaos, Zhou Mu, born with inadequate soul intensity and physical prowess, struggles to become an esteemed Animal Whisperer. 

With only a low-tier grass snake as his spirit animal and limited chances to pass the Whisperer's test, Zhou Mu's future looks bleak. However, an unexpected twist comes with the discovery of a mysterious system that allows him to trade personal attributes for power. As he navigates this new potential, Zhou Mu faces the challenge of overcoming his limitations and rising to power in a world where strength determines one's fate.
