Li Du is a delivery rider, recognized as the "unluckiest" kind.
On a rainy night, he fell into a pawnshop he had never seen before - Cangsheng Pavilion. The blood on his forehead dripped on the ledger, and he saw the truth of the world:
Everyone is covered with "pawn marks". Health, memory, emotion, talent, luck... Everything can be pawned, refined, and bought and sold.
And his "bad luck" since he was a child was because his fate - Sangui Water - was born to absorb the "deficiency" of everyone around him.
What's even more cruel is that his mother pawned her health eighteen years ago in exchange for his surgery fees. After four rounds of compound interest, my mother only had four years left to live.
Xu Yanshen, the shopkeeper of Cangsheng Pavilion, told him: Want to redeem? Can. Trade all the luck you have left.
After pawning, you will live in constant bad luck and may not survive more than a year.
Li Du refused.
"The shortfall cannot be filled by pawns, but can only be supported by living."
He began to learn to identify patterns, redeem deeds, and modify deeds, and dealt with the forces of nine schools and ten schools - the Legalist order of Dianzong, the Mohist ideals of the Redemption Sect, He Tianhong's business wars, and Xu Yanshen's struggles with Confucianism who had been trapped for thousands of years.
He meets Su Zhi, a girl who has pawned her "ability to be loved". She remembered all the warmth, but could no longer feel the temperature. And he is the only one who can hear the "echo" in her heart.
In the end, Li Du will face a choice:
To be a blocked river or a river that is always flowing?
