A commander in the human army led the troops who also hated vampires to launch an attack on the vampires. Due to the suddenness, almost all the vampires were wiped out, and all Xilu's relatives died. In order to allow the vampire race to exist, each vampire contributed part of his or her own mana to temporarily transform Shen Tong, the most powerful and aristocratic blood, into a human and hide her memory, which will be restored automatically after five hundred years. The remaining vampires slowly developed new laws and hierarchies, and quietly began to reproduce. Under the law, Xilu became the acting queen of the vampire race.
Five hundred years later, when Shen Tong was about to lift the seal, Xilu led an army of vampires to attack humans, catching humans who had not experienced war for many years by surprise. After Shen Tong regained consciousness, Xilu abdicated. After that, the final battle with humans began. This is bound to be a bloody battle, but even if the losses are heavy, Xilu is bound to avenge his relatives. Farewell battle, this is the name of the last battle, drawn up by Xilu, which means the farewell battle.
Some settings:
1. Old Law: The law before the vampires were attacked
2. New law: newly revised law after vampires were attacked
3. The Upper Five Councils: Both the old law and the new law stipulate that the five most powerful people among the vampires will serve as the Upper Five Councils. One to five people will be ranked according to their strength to assist the queen in managing the remaining vampires. (Xilu's situation is an exception. Shen Tong's power is greater than hers, so Shen Tong takes over Xilu's throne after recovering. Xilu's power is smaller than Shen Tong's and is greater than the one from Shangwuhui, so he abdicates and becomes the first one from Shangwuhui)
4. One, two, three, four, five: There are also hierarchical divisions among the upper five societies. The most powerful one among the upper five societies is one, and so on for the others.
Concept: The war between vampires and humans
