Transmigrated to the Tang Dynasty as the village head of Wucheng, Su Changsheng planned to develop secretly and silently make a fortune. However, his distant cousin came to visit but was delayed by bandits. He then mistakenly met and took Li Shimin, who was making a private visit, as his cousin. Initially reluctant, Li Shimin, after a conversation, found it quite enjoyable. From then on, he became Su Changsheng's cousin.
