Ning Haitao, a master of materials science and engineering, unexpectedly came to the world of swordsmanship. In his eyes, the grass, trees, sand and stones in the base area are all unilluminated blueprints for weapons. Gathering grass to make saltpetre, scouring iron sand to make shrapnel, and flying with a kite. What the enemy sees as waste is the magic weapon in his hand that changes the situation of the war. War has always been based on science, when every inch of land roars for resistance. When "millet plus rifle" evolved into "everything can be equipped", the invaders truly realized what it means - everything can be equipped as a soldier.
