Global Class Change: I Contract a Sword Maiden from the Start

Transmigrated to a world where everyone changes class! Everyone in this world has a class of their own: Warrior, Tank, Mage, Marksman, Assassin… After repeating a grade for three years, Lu Xuan was branded the “most useless” student. At the school’s oath-taking ceremony, he rejected the school beauty’s confession and became everyone’s target! From the start, he contracted an peerless female sword immortal and obtained the Sword Art of Heaven and Earth! I, Lu Xuan, have a sword in hand! With one sword, I shall stand tall, and even the gods must yield!
