Lin Shen, a Ph. D. In physics and ballistics, unexpectedly broke into the world of martial arts and became an ordinary mortal with no cultivation or background. Faced with warriors who frequently broke mountains and cracked the earth, he abandoned the conventional methods of martial arts training and relied on solid scientific knowledge to skillfully use physical principles to survive in dangerous situations. As the world of Gaowu gained a firm foothold, Lin Shen hid in the mountains and used the most primitive tools to create the first gun-breaking handgun in the world of Gaowu. He integrated scientific theories such as chamber pressure, ballistics, and stress structure into weapon forging to create a thermal weapon capable of penetrating the body's protective gas.
