A Model of Righteousness by Day, a Giant of Demons by Night

But before he could enjoy the life of the second generation, the empress was jealous. Overnight, the father was imprisoned, the men were exiled, and the women were in the palace... Among the whole family, he was the only one who was lucky enough to survive, and he accompanied the imperial mission to the disaster area to provide relief as a guilty person. However, before arriving at the disaster area, the imperial team was intercepted and killed, leaving only Gu Chenfeng alone. Just when he was desperate, the Demonic Supreme System awakened. When he looked up again, his eyes had suddenly turned cold. First, he put on a purple robe, pretended to be a third-rank official of the imperial court, and took office as a fake imperial envoy. Secretly, he uses his domineering magic power to stir up the world, causing not a blade of grass to grow in his path. During the day, he is a model of righteousness and a great master who is loved by all people. In the dark night, there is the unscrupulous Demon Supreme! It wasn't until he returned from disaster relief and stood in front of the empress again that Gu Chenfeng chuckled and spoke. "Empress, you don't want to either..."
