Mecha Three Kingdoms: Traveler from the Future

Zuo Ci, champion of the 4023 Mecha Tournament, was transported to the Three Kingdoms era of 2183.

Zuo Ci couldn't help but marvel at how backward the mechas of the Three Kingdoms era were.

You have sixth-generation Tiger and Leopard Cavalry mechas? No problem. I have ninth-generation Black Armor Cavalry mechas, three generations ahead in performance and utterly dominant!

You have Trapped Camp mechas? No problem. I have Iron Pagoda mechas, whose flank armor is twice as thick as your main armor. Let's see whose is tougher!

You say you can shoot a halberd at the gate of your camp and hit a target a hundred paces away? No problem. I have a Gauss sniper rifle. I'll take out your sniper from eight hundred miles away!
