I'm From Alien Space

During his journey to a world where he could form contracts with spirit beasts, Xu Qian achieved the title of "corrector". It was after he contracted his first space-time beast and activated the system that he understood the significance of his new identity. Xu Qian's main objective then became to use the system to defend against foreign world attacks, while also fortifying his spirit beasts and the system. These events were originally depicted in the webcomic.
