I Became the Strongest in the Galaxy Through Mecha Repair

[Please check out my upcoming novel: The Whole Class Can Hear My Thoughts, and I'm a Brooding Edgelord] An unapologetically cool, badass heroine x a steady, self-possessed, aloof hero. Thanks~] Blurb: Huo Hanfu, a powerful plant user in the apocalypse, was ambushed and killed by zombies. When she opened her eyes again, she was a penniless outcast at a military academy, despised by everyone. And the poor thing was studying the expensive, exhausting major of mecha maintenance. Huo Hanfu: Maybe I should switch to botany and coast along? She thought as she used plants to repair a mecha. But when she asked, she learned that switching majors meant paying the difference in tuition fees!? - In the military academy league, most of the mechas belonging to the Federation's First Army had a green leaf emblem. Students from other military academies mocked them. "What, did you lose so badly that you had to change your school crest?" "Changing your crest won't fool me. I still know you're from the Federation's First Army!" "A new crest won't help. You'll still lose!" Then they got thoroughly thrashed by those mechas bearing the green leaf emblem. Huo Hanfu followed along behind them, showing off as she repaired the mechas that had been smashed to pieces, then stamped each one with a green leaf emblem. Huo Hanfu: This will get my mecha shop's name out there. The Federation's First Army, watching Huo Hanfu repair the enemy mechas: ??? Boss! The whole interstellar system is watching this competition! Winning is what will make you famous! Huo Hanfu: !!! Without pausing, she turned around and smashed those mechas to bits all over again. The other schools: Furious! But afraid to say a word! Must-read notes: 1. It's still female Alpha x male Omega. 2. Thank you, everyone. - Upcoming novel blurb: When Song An opened her eyes again, she had transmigrated to an interstellar world overrun by alien species and become a student in a training class for people with special abilities. On her first day of school, she discovered that every single classmate was a notorious villain from a novel! And she was a complete nobody, with a brooding edgelord personality: just an extra! As everyone knows, villains die, but extras don't. Song An: [Great! They'll all die, but I won't.] Classmates: ? Song An's inner voice rang out again: [Why is the martial arts class representative still here? If she hurries back now, she can still catch her boyfriend in a group hookup!] Martial arts class representative: ? [Wait, which water did the survival expert drink that made them explode and die?] Survival class representative: ? [Class monitor, she wasn't switched at birth. He's an illegitimate son!] Class monitor: ? - Later: The martial arts class representative, who was a demon, removed his horns. From then on, Song An gained the favor of the goddess of luck. The survival class representative, who was a spirit plant, pulled out one of their vines. From then on, Song An enjoyed nature's protection. The class monitor, who was a Buddhist sage, removed the halo of light behind his back. From then on, Song An was hailed as the savior. Song An: ... Song An: Time to show off! - One day, a new instructor arrived at the special abilities training class. The new instructor wore white embroidered with dark gold patterns, accentuating a tall, striking figure. Jiale: "Hello, everyone. I'll be joining your class from now on." As soon as he finished speaking, Jiale heard: [Wifey, come cuddle~] Jiale: ... Jiale: ? The entire class, eyes wide with shock: Hey, shut up, Chun! He's from the Highest Court!! - "I know your past, your thoughts, and your most vulgar desires." "I welcome the judgment of Jiale, judge of the Highest Court." - 1. This blurb is provisional. The premise won't change, though a few details might. 2. Move aside! I'm about to show off!! Theme: My homeland and its mountains and rivers are mine to protect
