According to legend, there was a clan of medicine men in ancient times who had a strange bloodline and were born with martial arts prodigies. The medicine man has no intention and can only marry someone of the same race. If the blood of a different race merges, a heart will grow in the chest, causing pain to death.
The medicine people were cursed from birth. In their first life, they were medicine people without any intention. In the second life, he was a mortal and died young. The third life will never enter reincarnation, wandering by the Naihe Bridge, and will never taste warmth for eternity.
