I Am Really a Swordsman, Why Do You Say I Am Jiahao?

My name is Lu Fan. I traveled across the earth from the fairy world. I thought this was a world where everything was fine. Unexpectedly, with the revival of spiritual energy, the demonic minions of the fairy world actually reached here! Ordinary people can't see the devil, they only know that on the court that day, a man was dancing with a sword... Classmate: "Jiahao is here! You guys talk first." Lu Fan: "It seems that there was a swordsman named Jiahao in this world." —————————— My name is Su Tingyue, a high school student who passed the examination of the Superpower Association. Because my academic qualifications are not enough to formally join the association, I can only complete my high school studies first. She thought she was a unique genius, until one day, she was defeated by a demon on the court. Someone next to her picked up her peach wood sword and opened the gate of heaven with one sword... "Senior! Please teach me how to practice swordsmanship!"
