In the fifteenth year of Chongzhen in the Ming Dynasty, on the eve of Li Zicheng's attack on Kaifeng, the dynasty was about to run out of power.
With the Dragon Veins of Kunlun Mountain as the core, it radiates to five ancient tombs: Hidden Dragon Cave in the Qinling Mountains, Guimen Gorge of the Yellow River, Dunhuang Xingyun Cave, and Worm Valley in Yunnan.
Captain Mojin has inherited the secret of guarding the Dragon Vein for thousands of years. At the end of the dynasty, he faces a double crisis - he must fight against natural and man-made disasters and prevent alien forces from seizing the Dragon Vein.
The dragon veins undergo a sudden change; Li Chengfeng discovers an ancient star map in Mang Mountain, Luoyang, which unexpectedly causes the dragon veins to move abnormally, and the blood rain from the sky indicates that the dynasty will fall.
The mystery of the ancient tombs; the team relied on the incomplete secret book of "Shaking the Dragon" to unravel the thousand-year layout of the Five Elements Chain Tombs, and found that each large tomb suppressed an earth-line evil dragon
The ultimate showdown; encountering the Blood Corpse King refined by the Jinyi Guards of the former dynasty in Kunlun Ruins, exposing the conspiracy of the Dongchang eunuchs and Jurchen shamans, and renewing the dragon's veins with the Yin Yang Jade Pendant
