Anti-Japanese War: I Used Geography to Fight the Japanese

In 1942, Li Yannong, a top geology student at Yanjing University who was forced to return to his hometown due to the fall of Peiping, faced the bloody iron hoof of the Japanese army's "May Day raids" and found that the villagers' traditional hiding holes and home-made landmines could not withstand the enemy's systematic raids. At the moment of life and death, he activated the golden finger of [Infinite Energy] and turned the weak scholar's body into a tireless "infrastructure maniac". He used his knowledge of geological exploration to plan a scientific, solid, and fully functional underground combat network for the whole village; he used structural mechanics to design life passages that were anti-collapse, anti-toxic, and waterproof; he relied on basic chemical knowledge to improve the gunpowder formula using local materials, and upgraded the land mines into a series of trick mines, directional mines, and even simple incendiary bombs that terrified the Japanese army. His talent soon attracted the attention of the county brigade and Japanese army engineer expert Takehiko Yamamoto. From then on, an underground offensive and defensive battle centered around "dig" and "fill", "bury" and "platoon" officially started. From the beginning, Li Yannong just wanted to save his family, and gradually grew into the "King of Geotechnical Engineering" and "Demolition Wizard" in the base area. Using the earth as a chessboard, he launched one thrilling intellectual duel after another with Takehiko Yamamoto, and eventually turned the land under his feet into a huge cemetery where the invaders were buried.
