Chapter 966 Breaking the City (Thanks for Calling Me Tian Ritian for the Reward)

During the First World War, Italy imported a batch of such artillery from France. After the war, a large number of second-hand goods were eliminated. The arms dealer ordered a batch of M1897. Later, these artillery were sold to the Nationalist Government. After a while, M1897 also came to the Eighth Route Army Independence Regiment, and these guns had Italian inscriptions engraved by Italian businessmen. At that time, our troops did not understand these and thought they were Italian products, so Li Yunlong called them "Italian guns".

Miss Seventy-five had been eliminated by Europe during World War II, but she was still quite a treasure in the Eighth Route Army. The Italian cannon from the Independent Regiment was hard to get. Due to the lack of shells, Li Yunlong was not very He was willing to use it, and in today's big battle, he finally made up his mind.

"Understood! Commander, just watch!" Shen Long pushed the cannon into place, measured the distance with a thumbs up, adjusted the firing angle, activated the precision talent, and the first shell hit directly. The machine gun position suddenly misfired, this is the real one shot into the soul.

"Scholar! You fucking did a good job! Go back and reward you with two catties of sweet potatoes! Work harder and hit that fire point!" Li Yunlong was overjoyed when he saw this. The heavy machine gun position just now crushed the Eighth Route Army They couldn't lift their heads up, and after knocking them off, their pressure suddenly decreased a lot.

"Understood!" Without saying a word, Shen Long immediately adjusted the muzzle and fired another shot at this point of fire. Under Li Yunlong's command, he fired all the remaining shells of the Italian cannon in one go. It was a direct hit, and every time it exploded, a devil's firepower point would disappear, and the little devils at the top of the city suffered heavy losses as a result.

"This cannon is really a fucking good thing, but it's a pity that our independent regiment has too few cannons." Seeing this scene, Li Yunlong was relieved and somewhat regretful, "Our independent regiment is as well-off as Chu Yunfei's 358 regiment That's fine, if we had Chu Yunfei's cannon battalion, we still need to dig tunnels so hard, and Ping'an County would have been taken down by us long ago."

"Leader, don't worry, this precious artillery battalion of Chu Yunfei, sooner or later even the people who carry the artillery will have to be surnamed Li!" Shen Long directly grabbed Li Yunlong's lines.

"Haha, that's a good point. The members of our independent regiment must have this kind of aura! If you like it, grab it back for us! But Chu Yunfei is helping us fight the little devils this time, and his artillery battalion Let him keep it for now, let's take down Ping'an County first and grab the little devil directly!" Li Yunlong laughed loudly, "The shells of the Italian artillery are gone, can you still shoot the mortar?"

"No problem, just move forward!" For Shen Long, no matter what kind of guns he is inaccurate, the only thing that can limit him is the number and range of the shells.

Li Yunlong had someone dig a tunnel to move forward, and then transported the mortar into the tunnel, and Shen Long would fire it himself. After firing a shot, he would change places, making it impossible for the little devil to fight back.

Shen Long wasn't just busy with himself,

He also had to spare time to command Monk Wei and the others and the second battalion under his command. He let the snipers suppress the top of the city, and Pan Fu went to guide the excavation of the tunnel. Monk Wei led people to continue to pretend to be a commando to attract the attention of the defenders , Continue to strengthen the pressure on the little devil.

At night, the independent regiment did not completely stop attacking. They continued to harass the city, using the sound of mortar explosions and machine gun fire to cover up the sound of tunnel digging.

The next day, when the sun was just rising, the tunnel was finally dug below the city wall, and explosives could be installed for detonation. Shen Long came to the tunnel in person and placed the explosive package that he personally made.

In the original novel, the city walls of Ping’an County were blasted open by blasters using explosives. In fact, given the thickness of the city walls of Ping’an County, just sticking explosives on the walls would not be able to blow up such a big gap, so Shen Long made improvements. , he specially shaped the explosives.

The American Monroe discovered the Monroe effect in 1888, also known as the energy-gathering effect; that is, after the explosive explodes, the explosion products basically fly outward along the normal direction of the explosive surface under high temperature and high pressure.

According to the example, after the detonation of the cylindrical grain, the detonation products will scatter around in the direction approximately perpendicular to the surface of the original grain, and only the detonation products at the end of the grain will act on the steel plate, and the area of ​​action is equal to that of the grain. The cylindrical powder column with a cone hole is different: when the detonation products in the cone hole part are scattered, they first concentrate on the axis and converge into a stream of high velocity and pressure, called the energy-gathering airflow, and the detonation product More energy is concentrated on a smaller area, and a deeper hole is punched on the steel plate, which is why the tapered hole can improve the destructive effect.

Using this principle, Shen Long calculated the weight and shape of the explosives needed to blow up the city wall of Ping'an County. After the modification, he installed the explosives, and then exited the tunnel to prepare for detonation.

"Scholar, can this little explosive work?" Seeing that the explosive he used was much less than he expected, Li Yunlong was not only puzzled.

"It's ok, I've figured it out, and these explosives are enough to blow up this section of the city wall!" Shen Long replied confidently. Although this thing is simple, it is a combination of Lao Bai, Ivan-Vanke, and others. With Arnim Zola's command of many super academic masters, it must not be underestimated; and the explosives installed by himself are much more than those in TV dramas.

Light the fuse, and the fuse burns into the tunnel with sparks. The soldiers of the independent regiment are ready to attack. The little devil seems to have realized something, and the number of soldiers appearing at the top of the city has increased a lot.

But this kind of behavior made their failure come faster. With a huge explosion, a huge V-shaped gap appeared in the city wall, and the attacking troops rushed up; the defenders at the top of the city were all shocked by the sound The explosion was stunned, and by the time they reacted, the soldiers of the independent regiment had already rushed into the city.

The ones rushing to the front were the special company led by Monk Wei, and the second battalion under Shen Long. The soldiers of the special company had excellent marksmanship and instantly suppressed the little devil. As more troops attacked the city wall, this battle There is no suspense about the outcome of the game.

That being the case, Li Yunlong was no longer interested in charging himself. He was even more curious about how Shen Long used such a small amount of explosives to cause so much damage just now. He grabbed Shen Long and asked, "Scholar, what is going on? Something? Teach me too?"

Captain Li, didn't you say, study, learn what? Why are you so easy to learn now?
