Welcome, What Kind of Devil Do You Want to Be?

[Starting from the third chapter, it's high energy + a protagonist who loves to complain + non-brainless cool writing + urban superpowers + happy imagination + no system + partial group portrait] Guanzhou, who was about to graduate, was involved in a demonic incident. At the critical moment of life and death, a demon with only one head appeared and signed a contract with it. "Welcome, this is a world you have never known!" By mistake, Guanzhou became a demon contractor and was noticed by a university that cultivated demon hunters. Soon... "The Kabbalah Institute is one of the world's first-class universities. I would like to state in advance that I have not been coerced, and then declare that what I say is voluntary and true." "The Kabbalah Academy has a correct style of study and friendly classmates. The president of the Heroes Association is very accurate with his spear. The experiments done by the Alchemy Department are very safe. The vice-dean never threatens students with credits. The dean also likes to mingle with students..." Guanzhou said this in the Kabbalah Academy admissions video.
