After Traveling to the Seven Deadly Sins, I Became Arrogant?

Lu Li only wanted to curse people as he was the most irresponsible sin of arrogance among the seven deadly sins. There is only one rule: there is a fake hidden among the Seven Sins, find him, kill him, and pass the level. Lu Li glanced at the blood on the throne, and then at the gray clothes on the sleeves - oh, he was the fake. If you are suspected, you will die, and if you kill someone, you will gain power. He has played the role of a social beast all his life, and now he wants to play the role of arrogance until everyone believes him, and then send them away one by one. The gluttonous strength, the lazy drowsiness, the jealous eyes, and the furious fire are all his nourishment. The sin of arrogance will never bow. If you bow your head, you will die.
