Hu Weidong couldn't help but think of the fourth and fifth battles in history during the period of resisting US aggression and aiding Korea, and the situation was surprisingly similar to what it is now. The same was the great improvement of equipment before the war, and then thought to himself, "When we used to have bad equipment, we all beat the American devils, and now that the shotguns have been replaced, it is not easy to kill them?" More importantly, after the enemy recognized his own strength, he paid more attention to defense, and no longer easily gave our army the opportunity to infiltrate, preferring to fight the so-called "dumb battle" for the battalion step by step, and offset the role of our army's new weapons with strong fortifications, and purely relied on the overall strength advantage to consume our army, which resulted in our army having good weapons, but suffered setbacks again and again, if it were not for the soldiers who later invented tunnel tactics, It is not easy to push the Americans back to the negotiating table

What especially gave Hu Weidong a headache was that the devil actually dug some tunnels under Jinan City, although due to time constraints, it should not be too long, but for the attacking troops who did not know the details, it was undoubtedly a great hidden danger, after the 15th Army entered Jinan City, the number of people who died because of the enemy's sneak attack behind them continued to rise, Hu Weidong learned about the situation on the front line and had to sigh and said, "I originally wanted to surprise the devil in the key battle, but I didn't expect to use it so soon."

"Such a small thing, really so useful?" The commander of one of the attacking troops looked at the new weapon that looked like a bazooka in the hands of the military personnel in his hands, and said suspiciously.

"Rest assured. As long as I hit this to the exit of the tunnel, a large number of devils in the tunnel will not want to live. Shiyan said with a confident smile. After a while, after the suppression of several machine gunners had secured the safety near the exit of a certain tunnel, he carefully pulled the trigger of the man-portable cloudburst shell in his hand, only to hear a whoosh, and the warhead with a caliber of less than 10 centimeters dragged into the tunnel with a tail flame. I only heard a loud "boom", and the tunnel mouth suddenly burst out of the red bright "cloud" more than one meter high, but fortunately, everyone had already taken precautions under the reminder of Shiyan personnel. There were no unnecessary casualties, but even if they were far enough, everyone could still feel the turbulent air currents and scorching temperatures

If it is a simple tunnel in the base area behind the enemy, such a violent explosion is likely to directly blow up a big hole, but the devil's tunnel construction standard is relatively high, and the inner wall of the tunnel made of two layers of red bricks and cement is supported by the surrounding soil layer, and it actually withstood this powerful explosion. But in this way, the power of the cloud burst bomb was unleashed to the letter, and the fiery shock wave that was enough to crush the human body raged all the way along the tunnel, burning or shocking to death countless devils hiding in it. Although the distant devils were not killed immediately, they were suffocated because the cloudburst bomb had exhausted the limited oxygen in the tunnel

Hearing a series of faintly visible screams from the ground, several soldiers who were closer immediately wanted to turn over and go down to check the results of the battle, but Shiyan personnel hurriedly dissuaded, "Don't go in yet." The oxygen in it is all depleted, and if you get in too early, you will suffocate and faint. ”

Although the head of the regiment is not very educated, he has received basic popular science education when he was studying at Kang University, so he still knows the concept of oxygen, and hurriedly stopped the impulsiveness of those young men, and waited for a few minutes. It was only after Shiyan nodded that people cautiously went down to the tunnel to check, and the young man with glasses repeatedly reminded several soldiers not to go too fast even after going down the tunnel, after all, the ventilation in the tunnel was not smooth, and the carbon dioxide concentration in the distance had not dropped so quickly

"It's all in pieces", if it weren't for the fact that several soldiers were veterans who had experienced the sea of corpses and blood, and they were afraid that they would vomit on the spot when they saw such a bloody scene, but the young shiyan officer behaved very calmly, which surprised everyone, but seeing the sad look on his face inadvertently, everyone didn't dare to ask more. They didn't know that in order to study this new weapon, more than a dozen military personnel died honorably, and several of them were blown to pieces on the spot because of the close distance, and the scene is exactly the same as what everyone sees now...,

After everyone walked silently for a while, they finally saw the complete corpse of the devil, these people did not have much damage on their bodies, but they were bleeding from their mouths and noses, and many people's eyes also burst out, and the death was even more hideous, "These people are far away, so they were not killed directly, but died from the high pressure caused by the deflagration, and their internal organs, especially the lung lobes, should have been broken."

"Alright, stop for now. If you go any further, you may encounter a living devil", Shiyan stopped the group, because he saw the corpses of several devils who were still clutching their throats to death, and knew that these people had died from the third lethal effect of the cloudburst bomb - negative oxygen asphyxiation. In a closed or semi-enclosed fortification, the lethality of this effect can be said to be the largest, but how far can it be, because the number of tests is not enough, even he, the Jishu personnel, is difficult to say accurately now, in order to prevent accidents, they first retreated to an exit found on the road just now and called for some helpers, and then boldly continued to move forward and complete the important data of Zuihou.

The Shiyan personnel were only satisfied that the power of the individual cloud burst bomb met the design requirements, while the commanders and fighters of the 15th Army who saw the power of this new type of ammunition for the first time were all pleasantly surprised, a warhead weighing several kilograms could wipe out all the enemies in the tunnel more than 100 meters long, which was really too effective. In addition to the incredible power, what particularly surprised them was that the lethality of the cloud burst bomb seemed to be completely unaffected by the tunnel bend, and at the same time, except for the enemy who was directly killed at a relatively close range, the weapons and ammunition on the other devils were basically intact, which undoubtedly surprised the anti-Japanese officers and soldiers who had been worried about the destruction of weapons and ammunition by the devils

But their regimental commander thought more long-term, "If the devil also has this weapon and uses it against our tunnel, then what should we do?" ”

Everyone's faces suddenly became solemn, but the shiyan personnel couldn't help but smile when they heard this, "Don't worry, even if the devils seize a complete sample, with their industrial base and scientific and technological strength, they can't think of making it within ten years." If they want to imitate our cloud burst bomb, they must figure out the exact molecular structure of our deflagration agent, which is not an easy task. ”……，
