As the leader of the demon sect, Yan Su-Yun lived a difficult, wretched life. It is only as he is dying that he realizes he never lived the life he truly wanted. Reborn as a child, Su-Yun is now determined to be an honorary elder of the powerful Wulin Alliance, one of the many enemies of the demon sect. Despite his aspirations, Su-Yun is only a puny kid and has much to learn of the alliance’s ways. With his second life hanging in the balance, can Su-Yun go from absolute demon to absolute master?
