Is My Jiaxin Qingmei Really a Swordsman?

[Single heroine + childhood sweetheart + lighthearted comedy + urban superpower + sequence] The whole school knew that Xu Nian was beautiful, but unfortunately he was just "Jiaxin". Killing monsters with bare hands in the playground on a rainy day, preaching in the middle of the night that there is a ghost in the teaching building, and telling Chi Du seriously when he was a child: "I came back from the future." Chi Du had been crazy with her for more than ten years, and even enrolled in the eight-year clinical medicine program, thinking that after completing the course, he could show her her brain. Until late one night, he reached out and patted a "child" on the roadside on the shoulder. The thing slowly raised its head and stared at him with its round black eyes: "Living... Human?" Chi Du was silent. Broken. Xu Nian seems to be fine. And what's even more outrageous is—— When he pressed down on the ghost and asked it to "stop moving", it really stopped moving. From that day on, Chi Du discovered that this seemingly ordinary university contained awakened people, demons, strange beasts, ghosts, and a world he had never really understood. As for his Qingmei who everyone said was sick? She is truly a swordsman. As for Chi Du himself? Official test result: Sequence 698 [Summoning]. But why are the things he summoned getting more and more wrong?
