There Is a Green Tea System and It's so Hard for Me!

Makize Kai traveled to a world and was bound to a system called Green Tea. The system really lives up to its name. The tasks released by other systems are simple and have many rewards, which is good, but the tasks released by other systems are difficult and have few rewards. As soon as Mu Zekai complains, the system will say in a voice that makes people want to vomit: "Host, it's not Chacha's fault!" Mu Zekai was fooled by the green tea at first, and when the system said anything after that, Mu Zekai said in his heart: Fuck you, green tea bitch.
