Comprehensive Comic: People Are in a Mixed School, Bound to the Imaginary Number Tree!

Li Yu traveled to a chaotic world where all realms merged - ghouls, angels, demons, and evil spirits all crowded together, and ordinary people were worse than wild dogs on the roadside. At the beginning, he was bound to the Tree of Concept, but what he wanted was not the Devil Fruit Tree or the Kabbalah Tree of Life. He directly chose the Tree of Imaginary Numbers - spatial power, infinite energy, photographic memory, and Herrscher-level combat power from the beginning. As soon as he woke up, he was hit by a ghoul in the face. Li Yu had a slight thought, and the space collapsed, expelling all the cannibal monsters in the entire building into nothingness. The next day, the system urged him to report to Holy Power College. When he opened the door of the student union, he saw Sona Shitori sitting behind the desk - heir to the demon lord and the next head of the Sidi family. Cang Na froze on the spot. Li Yu took the school uniform and threw it into the void, turned around and followed her to the classroom. As he passed by the corridor, he sensed the hot red-haired scent coming from the next classroom - Rias Gremory, the Demon Royal Family. He curled his lips and said to the system in his mind: "This school food is good - the red-haired one, I want to try it." This novel and its characters are purely fictitious.
