Thousands of years ago, China was in chaos, and three clans of demons and immortals stood in power.
People have greed, immortals also have it, and demons even more so.
Humans seek immortality, immortals seek ascension, and demons seek not to be eliminated by the superior.
The land of China, which had been peaceful for 200,000 years, was once again in turmoil.
For greed, they re-entered the territory of other people, and a war broke out.
The ten-thousand-year contract is broken, and everyone is ready to take action...
Purpose: I understand your darkness and am willing to go there with you.
