Looking at the Moon with Left Hand

Dark night has fallen, the moon is as bright as blood, and cowardly humans can only survive in the shelter left by their ancestors. Some humans have awakened special powers and turned into spirit messengers. The mysterious demon king has descended into the body of an ordinary boy. The strange forest, the frosty land, the death of relatives... Familiar scenes flashed through his mind like ghosts. After inheriting the power of the demons, he has to bear the backlash this power brings to him. Another mysterious ancient power was produced in his body at the same time, the damage system (gaining power by being hurt). Inexplicable pain and loneliness suddenly emerged in his heart, but it was unspeakable, pain! He needed more pain, the pain and hurt made him stronger.
