It’s Only Natural for a Prince to Have a Billion or So Underlings

Rebirth + System + hilarious antics + conquest + mastermind + summoning As a noble royal heir, having a few million underlings is perfectly reasonable. The Web, Quicksand, the Embroidered Guard, the Eastern Depot, the Western Depot, the World Society, and my own Evil Blade: yes, they all serve under me! As a prince, having advanced mechanical engineering is only natural. My opponent stared at the sky full of flying experts and rows of devices with green, spear-tip-shaped barrels, lost in thought. A Gatling gun that saves lives, a Maxim gun wielded by a benevolent healer, Dongfeng Express that delivers with 31-Mach precision: that’s all basic stuff. A nuclear-powered aircraft carrier? Please. I’ll build a space carrier! You’ve got numbers on your side? I’ll mass-produce autonomous drones and mech warriors! (There’s too much to write, help me come up with the rest.)
