Martial Arts: I Became a Saint by Being Beaten and Injured

The demon sect was wiped out, my master died tragically, and I was seriously injured and on the verge of death. Awakening the system of retaliation for being beaten, the more ruthless the enemy is, the stronger I am. Now the second senior brother wants to elect me to be the leader. The succession ceremony will be held tomorrow, just in time to hold the demon sect's sacrificial flag.
