There is a Miao tribe hidden in the Shiwan Mountains in southern Xinjiang. They are good at controlling Gu insects, but their weapon is a green flute. They did not want to interact with the people of the Central Plains and farmed their own food. However, a failure in controlling the poison caused a disaster. The poison backfired and corpses were everywhere. Very few people survived. They had no choice but to set foot in the Central Plains to find the clan's most precious "cold jade" left in the Central Plains, and to eliminate the hostility in the Gu insects in the tribe's territory.
