As a programmer, Li Ran died suddenly and his soul was attached to the body of a 9-year-old boy who went down the river to catch fish but was hit by the current and hit a rock. Unfortunately, it was just a few days after the Xuanwumen Incident. The Xiaohe Village where the boy lived belonged to Gaoling. Because Li Ran had just traveled through time, he didn't understand the pronunciation here, didn't know where this place was, and he couldn't realize that the Turks were about to move south. Can Li Ran get rid of this crisis?
