Anti-Japanese War: Return to the Killing Tiger's Mouth

Ling Yufei, a school bully, traveled through the Anti-Japanese War and arrived at the Killing Tiger's Mouth area. He had heard for a long time that the people here were tough and tough, and it was said that "once you enter the Killing Tiger's Mouth, it will be difficult to walk on the world." What can a weak academic master do in this crisis-ridden and complex world of the Anti-Japanese War? Fortunately, he actually integrated the Yan Shuangying-level King of Soldiers system. Not only is his marksmanship extremely accurate, but his cold weapon fighting speed is three times that of ordinary people. He is also familiar with various military equipment and special agent skills, and can even use heretical techniques with ease. He has become more aware of the knowledge base system, is familiar with military industry, and can integrate various military industry materials. In this way, the local guerrilla armed forces have much more equipment than before. Investigation, negotiation, ambush, sniping, rescue, and breakout are all done with ease. "Retreat? Impossible. Show off our equipment and it's not complete until we surround the enemy!" This novel and its characters are purely fictitious. Any similarity is purely coincidental. Do not imitate.
