Reincarnated as the Emperor Armor, and the Campus Beauty Wants to Fuse with Me?

Chen Xiu transmigrates into the Armor Hero world and becomes the Emperor Armor. He takes over for Tiandao, beating the Alien Beasts to a pulp. After decapitating the Black Demon Beast with a single strike in the final battle, he is swept away by a mysterious spatial rift. After traveling through time and space for a long time, he reverts to his belt form, preserving as much of his strength as possible. The aloof campus beauty Ji Ruyu summons him as her weapon! A divine artifact conceals its brilliance, so everyone thinks this is just an ordinary belt. The potential evaluator even rates it F-class! Chen Xiu: You're a useless machine. What gives you the right to judge me? I, Ji Ruyu, was a god-tier weapon master in my previous life. My weapon was an ordinary long saber with E-class potential. Thanks to a stroke of fortune, it advanced to the S-class Ruination Blade, and I became the human race's greatest saber god of my generation. Unfortunately, a traitor betrayed me, and I was killed by more than a hundred god-tier demonic beasts! Reborn at eighteen, at the moment of my awakening, I was confident I could cultivate my saber into the SSS-class Destruction Demon Blade and avenge myself! But what the hell is this? I stared at the ancient, dull toy belt before me. Ji Ruyu was going mad inside. “Wait, where's my saber? Where's my forty-meter-long saber?” “It's over. I died before I could achieve anything. The saber god of an entire generation doesn't even have a saber anymore. How can I still call myself the saber god?” Just as Ji Ruyu fell into despair, Chen Xiu awakened. “Fuse with me, and you'll gain invincible power!” They fused, and the Emperor Armor once again revealed its invincible might! “Wait, I'm the saber god! Let me train with a sword. No, I won't. I'd rather die!” After wielding the Aurora Sword and defeating a commander-class demonic beast with the strength of a soldier-class fighter... “I'll train with it. The sword is exactly what I'll train with!” When hundreds of demonic beasts surrounded them and Ji Ruyu was beaten out of their fusion, Chen Xiu stepped in to fight for her. “Without a person inside, the armor is even stronger! Sword, come to me!”
