Li Qian, a modern person from the 21st century, accidentally transmigrated into the body of a useless crown prince who was despised by everyone in ancient times. Right after he transmigrated, he was framed. Li Tai conspired with Princess Wei, Chen Ziyu, and fabricated the false appearance that Li Qian had defiled his sister-in-law. Emperor Li Shimin was enraged. Li Qian took advantage of the situation, intensified the conflict, and voluntarily requested to be removed from the position of crown prince. He was whipped three times, and the father-son relationship was severed. Then he was exiled to the barren and remote Ningyuan County. Li Qian utilized his modern knowledge to transform Ningyuan County.
