I Start Martial Arts School at a Hundred, and the Campus Belle Says She's My Wife?

At a hundred years old, Lin Xuan should have been enjoying life in earnest, but the System forced him to enroll in a martial arts school. Just as he thought he could set out on the path to supreme martial prowess, he unexpectedly realized that the aloof campus beauty at his school was acting strangely. She gave his grandson a bank card and was even willing to offer him martial arts pointers! When he got hurt sparring with someone, she actually stepped in on his behalf! She even brought him pills, rare treasures, alloy weapons... Lin Xuan thought she was interested in his grandson, but to his surprise, she was interested in him! I’m already a hundred, and someone’s got their eye on me! Wait, is she calling me “husband”? No, she’s after my body! Damn it, she didn’t invite me to the hotel to discuss martial arts! Ye Qingyue transferred schools to find her in-game partner from two years ago. As she searched for him, she gradually discovered that her partner was a little old: he was actually a hundred years old! Everyone, I need advice: I’m eighteen this year, so how do I pursue a hundred-year-old man? Should I just call him “husband,” or drag him to a hotel to discuss martial arts? Never mind. I’ll win over his grandson first and get him to call me Grandma! I’ll give him more treasures. If you want to win a man’s heart, you have to get to the root of things first! But why... “Grandma, you brought too little soul iron. Grandpa found a whole soul iron mine!” “Grandma, this cultivation method of yours is no good. Grandpa gave me a Martial God-level one!” “Grandma, I don’t need this armor anymore. Grandpa wiped out all the strange beasts!” “Grandma, Grandpa has... become invincible in martial arts!” Ye Qingyue sighed softly. “Help Grandma one last time. Get your grandpa to come see me at the hotel tonight. I want to ask him about... the origins of martial arts...”
