Invasion of Another World: Making Armor at the Beginning

Chen Tian traveled to a world invaded by creatures from another world. In this world, wars with alien creatures occur almost every day, and humans can only passively defend. The first task after the system awakened was to make armor. After the armor was made, he resolutely mass-produced the armor and handed it over to soldiers who have been fighting against alien creatures all year round.
