I'm in Another World and Contracted with Future Humans to Upgrade.

On the Spiritual Pet Continent, everyone can only contract one spiritual pet. Lin Jin was regarded as a waste who could not contract, and was framed and pushed to the bottom of the cliff of death. When he was about to die, the Chaos Devouring Body awakened in his body and made a contract with the ferocious Thunder Wolf that was chasing him. Before he could take a breath, the sky tore apart, and a beautiful figure fell with the stars. "You... You idiot, what have you turned me into?!" The female voice that sounded in my mind was filled with shame and anger. Lin Jin looked at the beautiful Kong Ming Beast in front of him and was stunned. But he doesn't know that all these are regarded as perfect experimental products by visitors from other worlds... Accompany him in another world to fight zombies and save the world!
