A customer asked me to repair their mech — I just gave them a brand-new one instead

"Son! Mom and Dad are off—don't miss us too much!" The you man stood at home, staring at the letter in his hand, frozen in shock. "Son! We aren't *that* heartless; we’ve set you up with a mecha repair shop. Work hard, okay?" The you man: "..." "You call this dilapidated warehouse a mecha repair shop??" Just then, a system awakened; the ramshackle warehouse before him instantly transformed into the most powerful mecha repair shop on the planet. "Boss... isn't your repair fee a bit steep? It's just an 'Earth-class' mecha—you want 1.5 million? You're a rip-off artist!" A you woman gazed at her beloved mecha and the exorbitant repair bill, torn by a painful dilemma. The you shop owner: "Not only can I fix it, but I can also awaken a talent skill for your mecha!" "Can you really bear to let your mecha turn into a pile of scrap metal like this?" "Are you crazy?! I just came in for routine maintenance—you want to charge me 10 billion?!" "This maintenance could propel you to the pinnacle of the galaxy; won't you reconsider? Of course, I also offer custom upgrades—talent skills, rare armor, 'Truth-class' materials... I’ve got it all, and satisfaction is guaranteed!" When an alien invasion struck and a tide of Star Beasts surged forth, "Truth-class" mechas rose majestically across the Blue Star Alliance's defense lines. The you man took the lead, sweeping through the enemy ranks with unstoppable force. Everyone: "We told you to run a repair shop, not start a mecha war that shakes the galaxy??"
