Dragon Vein Solitary Lord

In the land of Zhongzhou, the dragon veins are hidden, and the spiritual energy is like a dragon. If you touch it, you can become an immortal and live forever. However, the dragon veins are guarded, and the hidden clan calls itself "Dragon Descendants", and uses blood as a contract to maintain the peace for thousands of years. The eight tribes of Zhongzhou, Qi, Wang, Huang, Dugu, Zhuge, Xuanyuan, Li, and Zheng, jointly elected the Xuanyuan family as the "Co-Master of the Dragon Vein" three hundred years ago, and held the contract to control the Yuan. Three hundred years later, Xuanyuan Lingtian's body was as weak as a candle, but he only knew the secret of the dragon's veins. The seven clans are undercurrent, poisonous spiders, sword formations, Netherworld, fortune-telling... Each has their own evil intentions, and they want to kill Xuanyuan and seize immortality.
