Drinking the moon is the honorific title of Zhou Xianren to the statue of the Ming dragon in the previous generation, and it is a thousand-year race. Ming people will not die, but will be reincarnated, and each reincarnation will not have the memory of previous lives, so they will not fall into the demon body.
Only those who have a dragon face and inherit the dragon heart can take over. In fact, the Millennium is the present dragon statue of Ming Dynasty, but it can't be completely recognized as the present dragon statue because it has no memory of the past dragon statue after the inheritance ceremony.
