i secretly develop myself in the demon world

Su Nan accidentally came into contact with a game called "Demon World" and obtained a unique talent. Just as he thought he would showcase his skills in the game, he discovered various signs indicating that the game he played was not simple. Rampaging players, immortal demons, possessed monsters... All sorts of incredible things happened one after another, and the real world gradually became bizarre. Sensing the danger around him, Su Nan decisively chose to secretly develop himself. When the game merged with reality, he looked back and realized that he had long become the biggest demon in the eyes of the players.
