Transmigrating to Cultivate Immortality: From the Start, I Had a Barrett

War King Li Mubai transmigrates to a fantasy world and awakens the Military Arms System. He gathers resources, upgrades weapons and equipment, and builds a technologically advanced nation in a world of fantasy. You have immortal arts and spiritual techniques; I have unlimited ammunition. You fly on swords; I have fighter jets for escort. You have a grand protective formation around your mountain; I have laser guidance. A mortal body standing shoulder to shoulder with the gods... I, Li Mubai, am the one who will forge a new order in this fantasy world.
