Special Forces soldier Lin Yue accidentally obtained two crossing gates, one connected to the modern secret warehouse and the other connected to the 1938 Eighth Route Army base area. While the Japanese were still using the 38-meter cover, he had already sent sniper rifles and anti-tank mines to the base area. The political commissar said he was too arrogant, but he used modern tactics to make the Japanese suffer. Until a piece of top-secret information revealed that a "traveler" had also appeared within the Japs.
