During the Shaoxing period of the Southern Song Dynasty, Liu Chai, a crab collector, was ordered to go to Wujiang to collect tribute crabs. A sudden earthquake engulfed all the people traveling with him and the crab boat, leaving only a few survivors.
At the same time, a group of northern rebels lurking around Lin'an City showed up, slaughtered people along the river, and forced Liu Chai to sail into the pass. They tried to use the identity of a crab collector to sneak into Guanglu Temple, go to the Mid-Autumn Festival celebration site, and kidnap the emperor to command the world.
In the process, Liu Chao suddenly discovered that the flag that controlled the situation in the world had fallen into his own hands without knowing it.

Let's see how a little crab collector can break through many dangers, survive from desperate situations, and save the Song Dynasty from fire and water!
