Li Manlong, a military technology guru, had an accident while testing new equipment. He traveled to the world of "Bright Sword" and became an ordinary arsenal technician in the independent regiment. He has access to an "Equipment Upgrade" system that can consume "Kill Contribution Points" to upgrade existing equipment. As a result, the style of the independent regiment began to change: Hanyang-made guns capable of firing continuously, 38-inch guns equipped with simple sights, mortars with twice the range... Li Manlong became Li Yunlong's most inseparable treasure.
