God Level, I Can Create Systems

After traveling through time, Lin Yan discovered that he was actually bound to a god-level system! Can a god-level system also establish sub-systems? So strong? Lin Yan: "Is there a subsystem that can be upgraded by breathing?" According to the judgment of the main system, the host needs to breathe continuously for thirteen years and two hundred and eighty-five days in order to obtain enough ability values to increase the level. Lin Yan: "Is there any sub-system that can be upgraded by eating and drinking?" According to the main system's judgment, the host needs to drink 7,000 liters of water or eat 5,000 kilograms of food in order to obtain enough ability points to increase the level. Does the host confirm the establishment of this subsystem? "No, no, no! I'll think about it again!" This novel and its characters are purely fictitious.
