In the forgotten corner of the world, Shen Qinghe is the last memory transplanter who has mastered the art of grafting vegetation and memory at the same time. He can graft new branches to dying ancient trees, and he can also implant a memory that is not his own into a broken life. This skill was passed down from his grandfather. There is an iron law that cannot be violated. Grafting memory must take away an equal amount of the person's original memory in exchange. However, when a When a woman who only wanted to remove painful memories but not fill in the blanks found him, Shen Qinghe was shaken. He hid the deleted memory fragments without permission. From then on, those memories were like dead branches that failed to be grafted, growing wildly in his dreams and gradually eroding reality. And he found that all the memories pointed to an old event that had been covered up, tightly entwined with the secrets of his family.
