Xu Siyuan has the ability that when she dies, she will come back to life in another person who has just died. Although the living soul can make the dead body decay more slowly, it only delays it. Only when she removes the cause of her death can this decay cease, allowing her to live in this form until her next death. If she cannot eliminate it, then her soul can only be locked in this gradually decaying body, along with the body, slowly fester until it dies and enters the next body.
And the dead soul will never be freed.
Death is not the best solution, there is always a way out in life.
Motto: There is always a way out in life
