Rebellious Disciple

Question: What is the greatest evil in the world? Not the demons with a bloodthirsty nature, not the evil spirits bred by resentment, not the ghosts of the underworld. It was the boy who once stood in the sun. He had fought bloody battles for the common people, and had also withstood a fatal blow for his true love. He was once the purest, most dazzling, and most trustworthy Senior Brother of Shushan. Everyone thought that he would become the greatest guardian of righteousness for thousands of years. Until he broke his sword with his own hands.
