He Fengyu, an ordinary young man who was teased by fate, accidentally obtained the "Stand-in Lottery System"-as long as he completed the commission of others, he could draw various stand-in abilities. From the delivery boy cosplaying as a rich second generation to attend class reunions, to taking the place of business bosses in dangerous negotiations, he dances on the edge of a knife every day.
However, a seemingly simple "substitute" mission made him involved in a Shura field that spanned the five major forces. The wealthy daughter regarded him as Bai Yueguang's stand-in, and the gangster asked him to play the role of the deceased eldest son, and he even had to dance repeatedly in front of three beauties. His neighbor Fatty Zhao secretly covets his secrets and presses him step by step.
When multiple identities began to collapse one after another, He Fengyu discovered that there was a deadly conspiracy hidden behind each commission. He must use all kinds of strange stand-in abilities to break the situation in the spider web of lies - until the mysterious man wearing a silver mask appears and tells him a shocking truth: he himself is the perfect stand-in for a big shot.
