Travel to Another World and Become a Warlord

The protagonist Nan Jianfei traveled to a different world and became a warlord. He recruited goblins, nomads, humans, vampires, dragons, and mages to form an army to conquer the world. Make steam engines and diesel engines to make steam tanks, make black powder and explosives to make muskets and artillery Gatlings. Conquer enemy nations with armored musketeers and steam tanks. Because I heard anime about goblins being unfaithful to beautiful girls, goblins are expendable in the military system, like cannon fodder. The human race is an elite combat force, the vampire race is aristocratic humans with dragon blood, the dragon race is a powerful combat power, and the mage is a large-scale AOE with snow, cooling, cold attacks, and fireballs and lightning strikes. Nomads are responsible for conducting guerrilla reconnaissance and raiding the rear.
