At this time, Zhu Liangcheng and Chi Peng also discovered the Japanese's abnormal behavior.

Chi Peng said: "Brig Commander, is the Japanese learning about our local work?"

Zhu Liangcheng stood up from behind the cannon mirror and said, "It's true."

"It's trouble now!" Chi Peng changed his face after thinking for a moment, and said, "The Japanese hid in the tunnel and couldn't come out. Our machine guns and cannons have no choice but to do anything to them!"

He paused and said, "In this way, the Japanese can dig the tunnel to the base of the city wall, or even dig it directly into the city! Then he can launch an attack on the city area directly! Not only are our machine guns all become decorations, but even the heavy artillery groups on the Guishan Fortress and the Snake Mountain Fortress can no longer block the Japanese infantry cluster!"

Zhu Liangcheng sneered: "The Japanese hid in the tunnel, so we really can't do anything to them?"

"The mortar shells can be shot into the tunnel, but our number of mortars is too small." Chi Peng scratched his head and said, "And if you use mortars, it will definitely attract crazy revenge from the Japanese artillery! Just our dozen 90mm mortars are probably not enough for the Japanese artillery cluster to be stuck in the teeth!"

Zhu Liangcheng shook his head and said, "Mortars must not work."

Chi Peng said: "Besides mortars, what else can I do?"

Zhu Liangcheng asked without answering, "Dapeng, have you heard of the Battle of the Somme?"

"The Battle of the Somme?" Chi Peng said blankly, "Which dynasty was this war in which dynasty? Why haven't I heard of it?"

"This is not a war in any dynasty." Zhu Liangcheng rolled his eyes and said, "This is a major battle on the Western Front of the last World War! The British and French coalition forces and German troops invested a total of more than three million troops, and the casualties on both sides combined exceeded one million, which is the bloodiest battle in the history of the world!"

"What, more than one million casualties?" Chi Peng said dumbfounded, "So tragic!"

The total number of casualties between the Chinese and Japanese armies in the Battle of Shanghai exceeded 400,000. Chi Peng felt that it was so tragic that it was too tragic. Unexpectedly, the two sides in the Battle of Somme actually suffered more than one million casualties!

Chi Peng had no way of unimagining what kind of cruel scene the Battle of the Somme was?

"No." Zhu Liangcheng nodded, "At the worst time, 60,000 British and French coalition forces died in one day!"

"The British guy looks so awesome, it turns out that there are such miserable times." Chi Peng said contemptuously and said, "But what does this have to do with us?"

"Of course it's related." Zhu Liangcheng said, "I just said that more than 60,000 people died in the British and French coalition forces in one day. Do you know how these more than 60,000 people died?"

Chi Peng said: "I'm beaten to death by the Germans."

"Only half of it." Zhu Liangcheng said, "To be precise, it was killed by the Germans with a Maxim heavy machine gun!"

"Oh, it turns out that he was killed by the Germans with a Maxim heavy machine gun." Chi Peng nodded and said, "But this still has nothing to do with us?"

Zhu Liangcheng waved his hand and said, "If you knew the attack method of the British and French coalition forces at that time, you wouldn't have said that."

"The way of attack by the British and French forces?" Chi Peng said blankly, "What method did they use? Does it have anything to do with us?"

Zhu Liangcheng said: "At that time, the British and French coalition forces attacked exactly the same as the Japanese on the opposite side. They all came up with the way to use local work to avoid the opponent's direct firepower!"

"Ah? This method was used by the British and French coalition forces?" Chi Peng said in surprise, "How did the German army kill the 60,000 British and French coalition forces with Maxim's heavy machine gun?"

Zhu Liangcheng said: "It's very simple, curve shooting!"

"Curvey shooting?" Chi Peng said in surprise, "Can heavy machine guns still shoot in curve?"

"Of course." Zhu Liangcheng nodded, "In fact, when the Maxim heavy machine gun first came out, it could not only kill the enemy by direct shooting, but also by curved shooting. However, later, due to the heavy machine gun's lethality, infantrymen from various countries gradually abandoned the intensive offensive formation, which greatly reduced the killing efficiency of the curved shooting, so it was gradually forgotten!"

After a pause, Zhu Liangcheng pointed to the half-man-high shooting hole on the wall of the bunker and said, "Now, you should understand why the group base deliberately left two rows of shooting holes when building these bunkers, and the upper row of shooting holes were all outer horoscopes, right? The group base had expected that the Japanese would do this, so they made arrangements in advance!"

"His grandma, it turns out that the group leader had expected it!" Chi Peng was very excited when he heard this, rolled up his sleeves and shouted, "Then what are we waiting for? Hurry up and finish the ball!"

After saying that, Chi Peng carried a civil-type 24 heavy machine gun over.

The Min-24 heavy machine gun is a copy of the Republic of China version of the Maxim heavy machine gun!

Since Maxim heavy machine gun can shoot in a curved manner, of course, the Civil 24 type can be!

Zhu Liangcheng grabbed Chi Peng and said angrily: "Dapeng, why are you anxious?"

"How can I not be anxious? What if the Japanese were asked to dig the trench..." At this point, Chi Peng suddenly stopped, and then a strange light appeared in his eyes, and he suddenly said, "Brig Commander, I understand..."

"Just know, there is no need to say it." Zhu Liangcheng waved his hand and said, "Although the group had expected the Japanese to do this, and had reserved shooting holes for curve shooting in each bunker, he didn't know where the Japanese would dig the tunnel, so the shooting parameters still need to be measured!"

While speaking, Zhu Liangcheng walked to the side of the Min-24 heavy machine gun that Chi Peng carried over, and then raised the shooting angle of the heavy machine gun bit by bit. Finally, the muzzle of the heavy machine gun was aimed at the outer eight-character shooting hole more than half a person high.

Then, Zhu Liangcheng said to Chi Peng again: "Dapeng, you personally control the heavy machine gun and only allow a single shot to shoot. You are absolutely not allowed to fire continuously, otherwise it may arouse the Japanese's alert."

"Don't worry!" Chi Peng said, "Isn't it just a single shot, there's no problem!"

While speaking, Chi Peng held the wooden grip of the heavy machine gun, and then gently pulled the trigger. The heavy machine gun immediately let out a dull low roar, which was indeed a single shot!

Zhu Liangcheng quickly put his eyes behind the cannon mirror and quickly adjusted the focal length.

However, after a while, Zhu Liangcheng did not find the bullet landing point.

Zhu Liangcheng said again: "Dapeng, hit another shot!"

Chi Peng gently pulled the trigger again, and the machine gun let out another dull low growl.

This time, Zhu Liangcheng finally saw the bullet landing point, which was at the attacking position of the Japanese more than 2,000 meters away, about fifty meters away from a tunnel that the Japanese were digging.

The shooting angle needs to be increased by a scale!
