Anti-Japanese War: I, Zhou Weiguo, Became a Great Power from the Moment I Signed the Snow Leopard

After traveling through time, Zhou Weiguo, who was seriously injured, found that he was forced to a dead end! Ahead is an impenetrable and steep mountain range, and behind is the Japanese pursuers who are eyeing them! We have run out of ammunition and food. Is it true that I, Zhou Weiguo, will die here today? Sorry, the unlimited sign-in system was successfully bound! As long as you have hatred in your heart, you can sign in to get high rewards and trigger unlimited critical hits! "Ding, you sign in and get a mg42 general machine gun, which triggers a 10x critical hit, and the number of rewards is multiplied by ten!" Looking at the sudden increase in weapons, Zhou Weiguo finally smiled. Can you little devil withstand this firepower?
