In Langlang Mountain, where a group of demons are entrenched, the existences at the bottom of the food chain are not fat goats, but countless working demons like the pig demon "Shitou". His daily life is to complete unskilled chores such as chopping endless firewood and polishing bald arrows under the shouts of the grumpy bear coach. His dream is just to have enough food and clothing, to get a more relaxed position as a small boss as soon as possible, and to get rid of the fate of "mountain patrol cannon fodder".
However, the king of Langlang Mountain gave an order to do a "big cause" - to ambush the mysterious caravan! The whole mountain suddenly fell into a state of "good fortune". Shitou and his crow spirit friends were forced to run around in circles due to outrageous mission targets, and even had to steal human pots late at night to refine poison!
But in the process of carrying out these ridiculous tasks, Shitou accidentally glimpsed the fatal crisis hidden behind this "great plan" - this is not about making achievements at all, but leading all the little demons towards the destruction of the group! Should I continue to act stupid and follow the crowd, or should I risk being turned into a roast suckling pig by Coach Xiong and do something?
When the king's ambition met the bleak reality, when the mountains and plains were filled with monsters and monsters, no one expected that the most inconspicuous little pig monster in Langlang Mountain, who only wanted to fish and survive, would become a key variable in determining the fate of this mountain...
