Are mortal people destined to be unable to practice? Han Tian didn't believe it. He was judged as a waste by the sect and expelled from the mountain gate. He should have died in the mortal world. But in a desperate situation, he awakened the forbidden thing in his body - the life-swallowing seal. Swallow spiritual energy, swallow cultivation, swallow life span... Even, swallowing human life.
