After traveling through time and being the son of Su Shuang, a horse merchant, Su Fenggang was drunk and drugged by Liu Bei in Taolin. He was preparing to seize the horse team by "killing the donkeys", but accidentally activated the check-in system and continuously drew "Strong Mountains and Rivers" and "Snake Spirit Body". The fifteen-year-old boy fought one against three, punched Guan Yu and kicked Zhang Fei, forcing Liu Bei to cry on the spot to clear up his innocence. The first rift in trust between Liu, Guan and Zhang after they became sworn brothers was completely torn apart in the peach forest night.
