I! the Strongest Supporting Character at the Start

Chen Ren travels into a parallel time and space that is a fusion of movies and novels. However, he is a supporting character with no sense of existence! He is so low-key that half of the class can't pronounce his name, and he is a man of air in the eyes of the goddess. You can't even walk on the street without being invisible! Well, that changes! Look at how I, Lao Yinbi, assist the protagonist while stealing his achievements and women. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
