In order to save the people of a city, Shen Qingqiu, the master of the Spiritual Medicine Valley, stepped into the abyss of sin.
He thanked the demon lord whose power came from sin and asked for the only antidote.
Xie Yao's bloody eyes smiled, and offered a cruel deal: "I can give you the medicine. But for every person you save, you have to share half of your life's sins with them."
From now on, saving people is a sin. The hands of the holy medical fairy were covered with invisible blood that could not be washed away. He hated the devil who dragged him into the quagmire, but because of his sins, his body became twisted and dependent on the devil.
When the whole world regards him as a fallen evil spirit, the incarnation of heaven comes and wants to kill him——
The Xie Yao whom he hated so much stood in front of him and fought against the whole world for him.
It wasn't until Shen Qingqiu saw the "sin account book" written in blood behind Xie Yao that he finally understood...
It turned out that all these crimes were the most twisted betrothal gift offered to him by Xie Yao.
—— "If it is a sin to save you, I will gladly do so."
