A certain villager’s pregnant woman walked towards it and wanted to give the cursed child to Joe. Magu, it means that the child should not be born, otherwise it will lead to insults. At night, the lady chose to hang herself, but at the moment of death, the child was born as expected, but there was no crying. The mother-in-law in the village said that the child should not be killed. Cursed, there is no soul and cannot be killed. This child's previous life has formed an enmity with Unkillable.

In the night of the same day, his family was also killed. The priest's mother-in-law explained that he was not dead. After the killing, there will be no living in the village. The male villagers are angry and scared to find the cursed child. The boy fled to the ice lake and fell into the lake. The boy was rescued, and the people in the village still did not let him go.

When he was attacked by villagers on the mountain, Duan Huo saw the woman who shielded him back then. It turned out that she just didn't die.
Duan Huo remembered that he had never touched a child or company, and had been haunted by the curse. Now the child was hired because of him, and he went up the mountain alone to look for the unkillable shadow, but the unkillable also pursued the camp and destroyed all the army. The lady of Duanhuo escaped to the mountain with her child, but Duanhuo was a step too late. When she saw her son, she was already exasperated. When she was about to hold her son tightly, she stabbed Duanhuo from behind, as if it was a soul transfer. In the same way, a woman gets a real soul, but Duanhuo has become unkillable.
