Science and Demon Suppression: I Weld Tianmen in Another World

Traveling through another world, Li Qingfeng became a mortal with no power to restrain a chicken. Facing the Sword Immortal Li Bai, the Overlord Xiang Yu and the Destroying Demon, he only relied on his knowledge of mathematics, physics and chemistry. If you don't have cultivation, you can use scientific principles to reproduce the magic; if you don't have resources, you can rely on chemical reactions to create magical objects. From "thunder" to "holy water", from levers to acid, he simply used scientific thinking to lay the first foundation stone in this fairy world. When the evil spirits from outside the territory came, he looked at the steel defense line behind him that he had participated in building, as well as the allies of all races who were united, and spoke calmly: "Don't be afraid, we have the lights of the third watch and the sword of science, which is enough to weld the gate of heaven and keep peace."
