Ten thousand years ago, the demon world was trying to seize dominance of the world and break the balance of the three realms.
This unprecedented war caused turmoil in the three realms and devastated all living beings.
In the end, the heaven sealed the demon king in the Yin-Yang Mirror, and the war had to be terminated.
For thousands of years, the winds and waves have been calm, and no one will mention the great war again.
But no one expected that after ten thousand years, the Demon Lord would actually escape from the Yin-Yang Mirror.
In order to prevent the war from thousands of years ago from reappearing in the world, Heaven sent Shangxian Ningjian and Chujiang King Aoyan to capture the Demon Lord.
But they didn't want to be attacked by someone, causing the two of them to fall into the mirror of reincarnation and start the journey of reincarnation.
In this life, Ao Yan was reborn as the prince, and Ning Jian was reborn as the prince's tutor. The two were entangled in love and hate.
Finally one day, Ning Jian woke up early...
"I thought you would save this place."
"Cold-blooded and ruthless, he is worthy of being a god who has cultivated the path of ruthlessness."
"Celestial rules? Divine punishment? It's not like I haven't suffered it before. I, Ao Xuan, have never been afraid of these things!"
Ning Jian was an unintentional cypress cultivating the ruthless path and becoming an immortal. Unexpectedly, he fell in love with Ao Xing the first time he met her.
The marriage written on the Three Lives Tree is destiny or man-made.
