Ghost Master: Who Gave You the Courage to Laugh at Zhong Kui?

This is a world where weirdness is rampant, and all kinds of weirdness pose a great threat to human beings. Human means are ineffective against Weirdness, and the only way to deal with Weirdness is to use Weirdness. Therefore, the profession of ghost master was born. Chu Xiu, a time traveler, possesses the most powerful talent in the history of the world. Everyone expected him to make a contract with Weirdness who had the potential of Yin Shen level (ninth level), but he contracted Weirdness who only had the potential of Evil Spirit level (first level). Chu Xiu turned from a genius to a waste in an instant, and was ridiculed by many people. His class teacher treated him coldly, his school beauty girlfriend left him, and top colleges also gave up on him. Chu Xiu didn't care at all, he knew that he would become the strongest in the world. Because the "weird" name of his contract is Zhong Kui. Many years later, Chu Xiu stood proudly on top of the world, making all weirdos feel despair. Those who laughed at him in the past were also slapped in the face: Class teacher: "I regret so much that I severed the teacher-student relationship with him because he was at a low point." School belle: "Chu Xiu, I was wrong. You are still the one I love most. Please give me a chance." Vice dean of three prestigious universities: "I had the opportunity to recruit him, but I gave up." "Let me go back in time and slap myself to death." "I regret it. I really regret it."
