Anti-Japanese War: Start with an Old Sleeve and Fight Ghosts with Gunfire

[Resistance + time travel + system + sniping + fighting the Japanese + decisive killing + rising behind enemy lines] Shen Qingshan, a modern sniper instructor, traveled back to 1937 as soon as he opened his eyes and became a famous good-for-nothing young master in Lutougou. At the beginning, the train was stopped by the Japanese. Wounded soldiers, civilians, and female students were all on the train. Machine guns were set up outside, and traitors led the way to search for people. Others were so scared that their legs weakened. He only had a broken old sleeve and three bullets in his hand. Fortunately, the mental shooting range comes along with the time travel. You can learn all kinds of sniper skills such as steadying the gun, measuring range, listening to the wind, hiding, and luring the enemy to shoot. Starting from a shot in the head of a Japanese machine gunner, Shen Qingshan snatched guns, rescued people, killed traitors, and attacked artillery towers. He just went from being a young master of the security team to a captain of the cold gun team that made the Japanese dare not raise their heads at night. Do the Japanese have gun towers? Beat. Dare the traitor lead the way? Kill. The enemy sent in snipers? Then let's fight cold guns to see who dies first!
