What Happened to the Protagonist's Common Sense?

Qihe traveled through a world that was strange, dark, chaotic, and almost absurd to him. What's worse is that he injured his brain, and most of the common sense in his brain is confused. It was a hell of a start. And he didn't know this until a long time after he came to the new world. By the time he knew he was sick, he had already taken out the devil's heart and set it on his throne. Because in his eyes, the devil's heart is the most beautiful gem in the world. The devil cannot be killed, but the devil's heart can regenerate. So Qihe imprisoned the devil. With his ex-boyfriend. He was not satisfied. ＊ In this world where angels and demons are everywhere, elves are numerous, and theology is mainstream, race represents a position, and bloodline has become the only criterion for measuring the value of life. The purer the bloodline, the greater the potential and the stronger the power. Human beings, the protagonists of the world in the past, were abandoned by this world long ago because of their mixed blood, and were lost in the dust of history. The appearance of Qihe, a human being, did not cause any waves at first, because he seemed so weak that a needle could pierce his skin and feel the warmth of the loss of life. "Pray, a beautiful but fragile little guy." This is what he, he, he and he said. But later on, such a seemingly fragile and incompetent human killed the great noble who tried to support him, and violently dragged the king of the evil dragon clan down from the Golden Mountain. … Later, the enemy politicians studied how Qihe rose all night and came to a conclusion. He believed that Qihe had made a deal with the devil, saying that he had seduced the good angel, and that he had stolen all his power and status through dirty means. After hearing this, Qihe smiled disdainfully, thinking that the devil is just a bird, and the one who can sit on his table must at least be a god.
