Master Xiu Xiu (Eric Tsang) has seven disciples, each named after the seven notes of the music score, and teaches them the Big Dipper Arhat Array every day. One day, Master Xiu Xiu went down the mountain to treat a patient, and left a letter before leaving, admonishing his disciples to practice martial arts and guard the mountain gate. As the saying goes, when there is no tiger in the mountain, the monkey is called the king. As soon as the master left, the mountain was immediately in chaos. The ancient temple contains the treasure of the Zhen Temple. The villains outside the temple have long been eyeing it. While Xiu Xiu went down the mountain, the four-man treasure-stealing group headed by Jiu Wenlong (Chen Sicheng) disguised themselves as incense tourists and waited for an opportunity to steal the treasure. Unexpectedly, they underestimated the seven little arhats, and fell into the trap that the seven little arhats seemed to have woven inadvertently as soon as they fought. Just when the little arhats felt that they had won, the angry Jiu Wenlong blew up the temple and held a little arhat hostage, and got the treasure of the Zhen Temple by accident in Xiu Xiu's Zen room. Seeing this, the little arhats regretted their decision to disobey their master and missed the big opportunity...
