Humans have never been the only kind of intelligent life on earth.
Non-human intelligent life forms are collectively referred to as alien races. Some of them disguise themselves as humans and hang out in the streets, while others live in no man's land and concentrate on practicing magic.
The Mi family and the Oran family, which were once the most powerful among the alien races, shouldered the responsibility of protecting mankind. But the last words of the ancient wizard warned them that the guardian must never let the guarded know their identity, otherwise both of them will fall into the abyss of eternal damnation.

But before the great changes, the world was always extremely peaceful.
Two young Mi tribe members, Lu Ming and Lu Yu, one is sensitive and cautious, the other is ruthless and vicious, but the least impressive one ends up becoming the king who saves the world, while the most lively and confident one has to go through a complete darkening.
Are the last words of the ancient wizard a malicious joke by the predecessors, or an irreversible holy word?
Facing the disaster that is about to destroy everything, all doubts will come, the mystery of the life experience of all aliens will eventually be revealed, and everyone will experience a painful choice... Who will be crushed and ashes, and who can rise to the nirvana of the phoenix?
