He was once the "Lord of Heaven's Law" who was in charge of punishment and order in the universe. Because he tried to build a new order that was superior to all ways, he was backlashed by Heaven and his soul was destroyed.
A remnant soul, carrying the final understanding of the word "karma", returned to the earth where life originated, and became a young man with an ordinary background - Su Yechen.
This time, he no longer pursues domineering and supreme power, but chooses to become an observer and organizer of "worldly fate".
In a corner of the bustling city, he runs an antique shop called "Chen Yuan Zhai". Every old thing is entangled with an unfinished cause and effect; every passer-by carries the thread of his own destiny.
The bad luck of the rich, the secrets of celebrities, the grievances of martial arts families, the rise of supernatural organizations... In Su Yechen's eyes, they are all cycles of cause and effect, and the laws of nature are clear.
As a mortal, he plucked the strings of fate.
When past enemies and old causes and effects came across time and space, and when the curtain of this world was slowly lifted, people discovered that the usually gentle and indifferent antique shop owner who seemed to have nothing to do with the world was the most untouchable person in this worldly city.
Because he is the king of cause and effect.
