[Western Crossover] Love Saves the World

[Blurb being improved] My name is Tian Wu. I have a father named Tianqi. He was the world's first mutant and the one who has lived the longest. He calls himself a god and thinks he's invincible. Ha! That's hilarious. I'm not bragging, but I could crush him with one finger. As the world's strongest known mutant, and the one who has lived the second longest, I've long since lost interest in the world. Every now and then, I even think about destroying it. But in reality, I'm a law-abiding citizen. When I learned that a group of people had stabbed my cheap old man to death, I decided to avenge him. We weren't close, but it was still the right thing to do. But who could have guessed that my one and only flaw, being bad with directions, would send me to the wrong place? I ended up in a dark city, where a few thugs tried to get handsy with me. Just as I was about to stab them to death and wipe this unpleasant city off the face of the Earth, a little bird flew right in front of me. "Hey, are you okay?" The mask he wore to disguise himself was useless in my eyes. Black hair, beautiful green eyes, and a stubborn personality. He was like a cat, and I fell for him at first sight. "Ah, I'm so scared. Can you hold me?" I trembled and wrapped my arms around him. To my father, now far away in the Temple of Death: This may be a little late, but your son seems to have fallen in love. And Gotham's actually pretty nice. Come visit sometime. P.S. The main story is written in third person. Theme: Love is being there for each other forever.
