Bright Sword: I took Li Yunlong to work in military industry

After successfully reaching a consensus with Li Yunlong, Li Yunlong was straightforward and arranged for someone to take Yu Ye to the Quartermaster Department and equip him with everything he needed according to Yu Ye's requirements.

There were just some minor incidents. The amount of explosives Yu Ye requested was a bit large, which directly used up one-third of the inventory.

However, since Li Yunlong has already agreed, it is not easy to go back on his word and he can only do as Yu Ye wishes.

Yu Ye is very confident in what he is going to do. This thing is not something he imagined out of thin air, but an effective heavy weapon that has been verified in actual combat.

He knew that if this thing could be used in the Middle East, it could definitely be used on the battlefield against the Japanese.

What Yu Ye wanted to make was the gas tank cannon, which was later commonly known as the Laiyang steel tube cannon on the Chinese Internet. Guerrillas on the battlefield in the Middle East even used this thing to shoot down American helicopters.

The background of the birth of this thing is also very funny. On the battlefield in the Middle East, a genius guy saw that his gas tank was stuck tightly into the sewer pipe after being bombed.

Then, he suddenly had an idea and thought, why don’t I use this thing to make a heavy cannon?

Launch the gas tank like a large mortar shell?

It has to be said that the war has driven the development of technology to an outrageous degree. This guy did what he said. He took out the gas tank at home, emptied the gas in it, and added more than 10 kilograms of explosives into it.

After continuous experiments, this guy actually did it.

The maximum range can reach an astonishing 800 meters, but the accuracy is a bit lacking, but the power is amazing enough.

According to estimates, the power of such a shell is equivalent to 3000 grenades, and one shell can directly collapse a two-story building.

You know, this is a two-story building with reinforced concrete structure. If it was replaced with a brick and stone structure like the current turret, it would probably be blown up by a single shot and razed to the ground on the spot.

When Yu Ye received these cast iron cans from the Quartermaster Department, he almost laughed out loud after a simple measurement.

The inner diameter of this cast iron pipe is about 500mm and the tank wall thickness is 50mm, so the structural strength is sufficient.

Moreover, there are not only thick pipes, but also several thin pipes with an outer diameter of exactly 450mm, as if they were specially prepared for Yu Ye.

However, this cast iron pipe has a flaw, which is that it is very brittle. Even if it is placed gently on the ground, it will often break due to its own weight.

This is not a problem for Yu Ye, as it only requires simple heat treatment.

He immediately started a fire, intending to heat the cast iron pipe and then temper it to increase its toughness.

While the thick pipe was being heat treated, Yu Ye also learned about the situation from the quartermaster. The pipe was taken back from outside the Japanese army camp by his guerrilla comrades from the county brigade, and was to be sent to the arsenal in the rear to be melted down and made into grenades.

According to the original purpose of this pipe, the Japanese were going to use it as a sewer pipe, but they didn't expect that it would end up benefiting Yu Ye.

This made Yu Ye laugh. Using the Japanese sewer pipes to send the Japanese to heaven was the perfect idea.

While Yu Ye was busy heating and tempering the thick pipe, he was also looking for tools to process the thin pipe. After all, there were no ready-made gas tanks for him to use at this time and place.

He has to do everything by himself.

In this era when there was a general lack of entertainment facilities, when they heard that a college student was making equipment to fight the Japanese, many soldiers who were not on duty or standing guard gathered around to watch.

As a result, Yu Ye had many good comrades who helped him for free.

But these tools are really shabby. After searching for a long time, I only borrowed a set from the old blacksmith in Yangcun. They can be used barely enough.

Yu Ye couldn't help but smile bitterly. He never expected that he, a great military industry tycoon, would end up doing the work of a rural blacksmith.

Even undergraduate students doing metalworking experiments such as making hammers would have more complete tools than this one.

What he was thinking now was that it would be nice to have something to do with his tools, even if it was just a lathe for home workshops.

Although he complained a lot, Yu Ye did not neglect his work at all.

Although he had no welding equipment, he even cast fins on the shell.

Out of respect for the craft, Yu Ye even roughly polished the front end of the "cannonball", which was indeed quite delicate.

Even with the help of enthusiastic Eighth Route Army comrades, Yu Ye was busy until the afternoon of the next day before he managed to complete the processing of the gun barrel, gun mount and three "shells".

Looking at these iron things leaning against the earthen wall, some Eighth Route Army comrades who had never seen Yu Ye asked: "College student, what are these? How come we have never seen them before?"

Yu Ye explained to them while eating a steamed bread: "This is a cannon!"

"Damn it, this can be called a cannon?" When Li Yunlong heard that Yu Ye had made the "cannon", he also ran over with his sleeves rolled up like an old farmer to watch the fun.

"Of course not. If it can be fired out and explode, then what else can it be called but a cannon?" Yu Ye said unhappily.

"Hey, this white-faced scholar."

After saying that, he waved his hand disdainfully and walked away.

Regardless of Li Yunlong's sarcasm, Yu Ye, with the help of several enthusiastic comrades, used a gun carriage to pull the cannon into the mountains and prepared for testing.

As for the gun mount, it was modified from a common cart in the village.

Since it was a test, Yu Ye did not put explosives in the shells, but instead put sand of almost the same weight to ensure counterweight. Then he wrapped the shells with a layer of rags, and then smeared a layer of butter that the soldiers used to clean their guns, to ensure that there was enough chamber pressure when firing.

Under everyone's attention, Yu Ye stuffed a ball of black powder propellant bag under the barrel of the gun. As he stuffed it, Yu Ye complained: "We are still too poor now. We don't even have nitrocellulose. Alas."

Strike a match and light the fuse.

Bang!

The cast iron shell made a hair-raising sound as it flew towards the distant mound of earth.

It hit the ground hard, splashing up a lot of dust.

Damn it?

Yu Ye looked at the broken pile of earth in the distance and couldn't help but swear.

In order to facilitate measurement, Yu Ye gathered several mounds of earth at the expected impact point. Unexpectedly, the range of the shell was as long as 5 meters, and it deviated from the expected impact point by only meters.

Yu Ye felt that he had to reward himself with a big "Awesome"!

With this guy in hand, building a watchtower would be a piece of cake, right?

Can Li Yunlong still show off in front of me?

There was no explosive in the shell, so it just made a hole when it landed on the soft soil. Yu Ye dug for a long time before he finally dug the shell out.

It is very difficult to find industrial products these days, this is simply a treasure.

After returning to the base with this "shell", Yu Ye opened the explosives he had received from the quartermaster department and looked at them with a look of disgust.

That's it?

Yu Ye knew what the ingredients were at a glance: rice bran powder plus nitroglycerin, definitely Zhou's explosives.

The quartermaster saw Yu Ye's disgusted look and said directly: "You are a student, you look down on this explosive?"

Yu Ye nodded subconsciously, then shook his head.

He just felt that it would be too difficult for his comrades in the Eighth Route Army to use such a weapon to face the well-trained Japanese devils.

"I tell you, if the commander hadn't given me special permission, I wouldn't have given you the explosives. Giving you some black fire is a sign of respect for you," the quartermaster said unhappily.

Yu Ye smiled bitterly and shook his head: "Let me tell you this, if I use your explosives now, I will return them to you ten times or a hundred times, and the power will be several times that of your explosives.

Do you think it's possible? "

"A young man like you with skinny arms and legs?" The quartermaster shook his head.

Yu Ye did not bother to argue and started loading explosives into the three shells. Each shell was filled with nearly 15 kilograms of Zhou's explosives.

Quality is not enough, quantity is needed.

At least we have to send those devils in the artillery tower to hell comfortably.

Zhao Gang saw all of Yu Ye's actions.

When the shells fired from the gun barrel really flew out more than 300 meters, Zhao Gang was still greatly surprised. He really didn't expect that just a few broken tubes could actually be fired under Yu Ye's operation.

There was a slight change in the way Zhao Gang looked at Yu Ye.

"Student Yu Ye, what you made... looks quite powerful!" Zhao Gang paused. He still couldn't connect these extremely simple iron pipes with "cannons".

"Haha, that's for sure, just wait and see."

"Political Commissar, can you arrange two guerrilla comrades to take me to the enemy's artillery tower for reconnaissance? This way we can fight a battle with confidence."

"Okay!" Zhao Gang readily agreed to Yu Ye's request.

Since Li Yunlong said that they were both pale-faced scholars, then let the pale-faced scholar teach his soldier a good lesson and let him feel a little shocked.
