Xue Yang had done evil all his life, and after his death, he was left with a left arm. In the palm of his left hand, he held the last candy Xiao Xingchen gave him.
This candy is slightly black and must not be eaten.
It was held too tightly and was already a little broken.
Cutting off his fingers at the age of seven cut off his good deeds; cutting off his arms before his death cut off his evil deeds.
If he were reborn, could there be a different ending?
