A "Flying Jade Pendant" that is said to have been given by Emperor Xuanzong of the Tang Dynasty to the envoys sent to the Tang Dynasty and contains clues to the secret treasure of Prince Li Xian after the "Dragon Coup" has appeared at an auction overseas. Lu Tianming was entrusted by a mysterious client to recapture the jade pendant, but he was involved in a shocking mystery that spanned the world. He discovered that this jade pendant was not only related to the huge treasure of the Tang Dynasty, which was used to revive the Li and Tang Dynasties - the "Dragon Relic", but also pointed to an ultimate secret that was said to be able to change the destiny of the country and was more precious than gold and silver - the "source of the dragon's veins".
