Cardo, an orphan of the blood clan who has lived for a thousand years, was exiled from the world after his family was destroyed when he was young. In order to take revenge, he practiced the forbidden technique of his ancestor "Blood River", which can swallow the defeated and turn them into his own use. On the East China Sea, he helped Li Jing, the military god of the Tang Dynasty, break through the Penglai Immortal Formation, but was planted an "immortal seed" by the Emperor of the Immortal Realm. This thing does not take life, but only uses strength as bait to lure him step by step to return to the fairy world. Within a hundred years, you will either become a slave of the immortals or destroy this world.
Kado chose the third path: to travel around the world, unite all races, borrow the power of Emperor Li Shimin, and gather the power of elves, dwarves, and dragons. Hibernating for hundreds of years, just to kill for nine days. When the river of blood swallows the sky, it will be the day when the immortal world overturns.
