I Changed Class to Traveler, and the Campus Belle Turned Out to Be the Grass Archon, Nahida

Games have merged with reality, and the age of universal class advancement has begun. On the day of class advancement, the campus beauty and childhood friend Lin Qian awakens the legendary support class [Dendro Archon: Nahida], sparking a nationwide scramble to recruit her. Meanwhile, the transmigrator Kongyu awakens as the [Traveler], a class with no starting element and nothing but a dull sword, and is mocked across the internet as worse than a miner. But only Kongyu knows this is a top-tier class that stands above them all! Unlock all seven elements and become an army of one! No element? You just haven't reached the Statues of The Seven in your inner sea of consciousness! No damage? That's because you don't understand elemental reactions! Most importantly, the locals in this world have no idea how elemental reactions work! To them, Electro and Dendro don't interact, while Hydro and Pyro can only cancel each other out. Only Kongyu and Lin Qian can trigger nuclear-level combos that defy the laws of the world! While everyone else is slowly whittling down enemies with fireball spells, Kongyu draws his one-handed sword and strikes back! Anemo [Gale Blade] to gather enemies and spread elements! Geo [Starfall Blade] to smash foes and grant a shield! Electro [Thunder Shadow Blade] to charge up and unleash a burst! When damage numbers like nuclear blasts start popping up, the world's strongest fighters are left dumbfounded. “Holy crap! Who said the Traveler was useless? This is a freaking human nuclear missile!” “Wait, why does the beautiful, wise goddess of a campus star only support that good-for-nothing?” Lin Qian wraps her arm around Kongyu's and smiles sweetly. “Because we're the Transmigrators' Alliance~”
