Yang Sizhen shows Wu Dacun a photo of Keiko Miyazawa. He has seen this woman before, and she is the one who turned against the boss. The Hundred Regiments War of the Eighth Route Army played a great role, and the Japanese army will certainly not let it go, which requires Wu Dacun's information to be accurate and timely. Yang Sizhen wants Wu Dacun to take her to join the army and fight against the Japanese army. She didn't want to associate with the Japanese against her will, but forced by the situation, Wu Dacun could only let her continue to endure.

The Japanese knew that they underestimated the Eighth Route Army, so they strengthened the layout of the war and deployed elite forces in the hope of winning the Eighth Route Army. The Japanese army is becoming more and more cruel. As soon as it entered the village, it burned and looted, which was extremely cruel. It took people's property, destroyed their houses and executed all the villagers. And their goal is more than that. They are still moving forward, killing innocent people. Their sweeping behavior made the Eighth Route Army very angry. The Eighth Route Army must take measures to suppress the enemy.

On this day, a soldier left behind on purpose, threw something into the tree and marked it. No one found his little tricks, and this man was one of Keiko Miyazawa's men who entered the Eighth Route Army that year. He found the Arsenal of the Eighth Route Army and let the Japanese know the news. The Japanese army immediately sent troops to destroy the arsenal and the source of the Eighth Route Army. The eighth route army in the arsenal was caught off guard, and the arsenal was in danger.
