Rural boy Chen Junyang followed his fellow villager sister Ruxue to Guancheng with a simple desire to "eat chicken butt". When she first arrived at the train station, Ruxue was harassed by gangsters. Chen Junyang unexpectedly received the inheritance from Master Erlang to unlock the Sky Eye, which allowed him to see through the gangsters' weaknesses and teach them a lesson. After arriving in Guancheng, Chen Junyang temporarily stayed in Ruxue's single apartment. He unexpectedly discovered that his eyes could penetrate objects, but he insisted on not peeking at Ruxue's bath.
