There is an iron law in Huaishu Town that no one dares to break:
Don't accept candy from strangers. Once you accept it, you have to return the gift with your heart.
No one remembers where this rule came from, and no one dares to ask.
Because every seven days, the memories of the entire town will be eaten away by the old locust tree.
Only blacksmith Lao Zhou remembers.
He remembered the blue and gray strip of cloth wrapped out of thin air on the handle of the hammer, the candy wrapper stuffed under the threshold, and the grocery storekeeper who died and came back to life, and lived and died again.
Seven rounds of cycles, seven times of forgetting.
When he dug up the seven rusty hammers on the barren slope, he finally discovered the truth——
What's in the jar isn't maltose, it's days that have been chewed;
The people walking around the town are not all people, they are candy figures made from locust trees.
And the daughter he had guarded all his life was the only living person he snatched back from Huai's mouth.
