System: Sorry, I Didn't Know I Was so Stupid

Sign in, develop, eat, drink water. All are rewarded. I didn't expect myself to be so stupid. But it was exposed by the school beauty sister! The words I write can enhance other people's talents. Any pet I feed can shock the world. Even the bones I spit out can nourish the earth. But where should I go? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
