Historical records record that he was extravagant and licentious, and his compatriots commented that he was mediocre and incompetent. It was Li Yuanji who played the role of a clown in the Xuanwu Gate Incident. However, this is just an illusion presented to the world. In reality, he is the secret pillar of the Li family and the modern successor of the Xuanmen sect. He protects the Northern Territory of the Tang Dynasty and targets the evil "Northern Territory Dragon Commander" with his sword. When the sword shadow of the Xuanwu Sect reflected the undercurrent of the demon clan, and when the secret realm of Lingnan revealed the secret of the ancient times, he gave up his power and devoted himself to a more grand battle. Joining hands with Shuanglong and uniting various families, what he protects is no longer limited to a dynasty, but the destiny of the entire human race. On this road leading to the end of the ancient world, he will eventually ascend the throne and become the guardian of the Tang Dynasty, which transcends imperial power, and even the human race.
