Ye Fei is a poor, down on his luck kitchen hand and could not pay his rent on time. After desperately dodging the landlady with some rash promises, he ducked into his room where he was electrocuted while turning on the lights.

Miraculously, he did not die. Instead, a strange [System] appeared in his head ordering him to do strange things like registering with a broadcasting network and performing strange feats in front of a camera!
