Chapter 79 Appointing military and political officials and transforming the Tiger Crouching Cannon
The examination venue for military and political officials was in the political hall.

After the exam, all 15 people stayed in their seats, waiting for Liu Sheng to correct the papers.

Sun Qifa tried his best to stay calm and looked through his notebook, trying not to look at Liu Sheng who was correcting papers.

This notebook was given to them by Liu Sheng after they were selected as military and political officials.They were also taught a method of making sketch pens using quills and bamboo tubes.

The words in his notebook are all simple characters written horizontally with a sketch pen.

At first, he used the sketch pen to write horizontally to the right according to the method taught by Liu Sheng, but he still felt a little uncomfortable.

But within two days, he and other military and political officials discovered that writing this way was much more convenient than writing with a brush held vertically - at least they didn't have to worry about their arms and sleeves blurring the handwriting.

Now that he is completely accustomed to the new way of writing, he is not so used to writing with the brush held vertically.

After flipping through a few pages of notes, Sun Qifa still couldn't help but look up at Liu Sheng who was correcting papers.

But seeing Liu Sheng's expression calm, it was impossible to infer their test scores this time.

"Zhao Deyou!"

A young man sitting in the first row stood up and said, "The students are here!"

"The test paper has been corrected, please send it out."

"Yes!"

Zhao Deyou stepped forward to get the test papers and distributed them quickly.

No one was surprised by this. Zhao Deyou had always performed well in Liu Sheng's previous lectures, so he was appointed as the academic committee member by Liu Sheng.

These 60 people were originally called the "Leader's Disciple Class", but now they are divided into the "Military and Political Class" and the "Teacher Class".

Sun Qifa got the test paper and found that he only scored 75 points.Although he knew that Liu Sheng always set the full score of the exam at 100 points, he didn't know what other people's scores were, and he didn't know how he did in the exam.

Wait for Zhao Deyou to finish handing out papers and sit down.

Liu Shengdao: "The top five in this exam are Zhao Deyou, Wang Dalu, An Jun, Wei Junjie, and Sun Qifai.

Sun Qifa was appointed as the military and political officer of the standing army garrisoned at Dashui Pingzhai, and Wei Junjie was appointed as the military and political officer of the standing army garrisoned at Hebian Camp.

An Jun and Wang Dalu were successively appointed as military and political officers of the standing army garrison in Xizomaling and Mopanzhai.Zhao Deyou served as a military and political officer of the Standing Army Garrison at Tongshan Iron Mine.

I'll give you a day off tomorrow. You can reunite with your family, pack your packages, and go to work the day after tomorrow.

Although military and political officers are mainly responsible for supervising military discipline, they are not supervising the army. If there is a war, you must also participate in the battle.

On weekdays, it is also necessary to teach the soldiers literacy and arithmetic, talk to them heart-to-heart, and learn more about what the soldiers think and want.

In the early stage, you can help them write letters home to get closer to each other... I have taught you how to become a qualified military and political officer, so I won't go into details here.

As the first batch of military and political officers of our Chinese army, I hope you can do a good job in all five, become an example for other military and political officers, and help me build an excellent army! "

Zhao Deyou, Sun Qifa and five other people listened to Liu Sheng's speech. They immediately stood up, performed the straight body and clasped fist salute taught by Liu Sheng, and shouted together: "Students, please obey!"

Ironworks.

It is built on a slope more than one mile northeast of Liujiazhai. After the road is repaired, it is not difficult to walk, but you must pass below Liujiazhai.

Unlike when the iron workshop was first built, there were only three blacksmiths, Mr. Wang and his son, now there are two master craftsmen, four blacksmiths and [-] apprentices.

The so-called craftsman comes from a craftsman rating system implemented by Liu Sheng in the Hua Department, namely: apprentice, craftsman, master craftsman, master craftsman, and craftsman clan.

An old blacksmith like Wang Tiechui who has high enough skills and is very sure to produce a qualified blacksmith is called a master craftsman.

As for the master craftsman, the Hua tribe does not yet have one, and the craftsman sect only has a vague concept.

Another master craftsman in the iron workshop is an old blacksmith named You Huowang who was kidnapped from Huilongji during Liu Sheng's actual military training.He also has a blacksmith son named Eugene Stone.

Originally, Wang Tiechui said that he had learned from his ancestors and refused to take outsiders as apprentices. However, Liu Sheng first pretended to be furious, making the Wang family and his son think that they were going to be killed. Then he offered him benefits - promising to bring out a qualified blacksmith. The reward is an acre of North American land.

Blacksmith Wang, whose ancestors had no land for eight generations, immediately compromised and threw the ancestral motto of "pass within, not to outsiders, from male to female" into the furnace and burned them all.

With the Wang family and his son as role models, the newly arrived You family father and son naturally had no reason to adhere to the stinky rule of "passing down the family from father to son", and they happily took up apprentices.On this day, a group of blacksmiths were busy returning the discarded weapons to the furnace to make armor plates, gun heads, and arrowheads, when they saw Liu Sheng coming over with two "thick iron pipes" between his arms.

"Bang!"

Hearing the clear sound of the "thick iron pipe" falling to the ground, Wang Tiechui and You Huowang couldn't help but look in surprise.

Wang Tiechui came over and touched the iron pipe. His old eyes widened and he trembled: "My dear, is this thick pipe made of fine iron?!"

You Huowang also took a closer look, and also trembled when he spoke, "It's really made of fine iron... It doesn't look like a mortal thing."

Wang Shiyi, Eugene Shi and other young blacksmiths also gathered around. With their limited knowledge, they also felt that these two thick pipes did not look like ordinary objects.

After thinking about the leader's "cave" and magic, they became even more convinced of this idea.

Liu Sheng said: "These two pipes are indeed made of fine iron, but not entirely. I brought them here today to let you see if you can help make them into artillery."

Wang Tiechui shook his head quickly when he heard this, "Chief, I have never made an artillery piece, and I don't know how to fire it."

You Huowang said: "I've never even seen an artillery piece, let alone how to shoot one."

Liu Sheng smiled and said: "You don't need to be able to do it, as long as you do what I say. If you fail, I won't blame you. If it succeeds, I will credit you, so there is no need to feel pressure."

"The leader has said so, let's try it."

Immediately, the blacksmiths in the iron workshop became busy to realize Liu Sheng's idea.

These two steel pipes have an inner diameter of 7 centimeters, an outer diameter of 8 centimeters, and a length of about 70 centimeters. They are one of Liu Sheng's items in the villa.

However, one of the original cannons was three meters long. Liu Sheng only stocked up on 10 of this type in order to make his own old-fashioned artillery pieces and use them as strategic weapons in the last days.

Now at the end of the Ming Dynasty, the Hua tribe was short of iron materials, and there were no craftsmen who could make cannons. Liu Sheng naturally thought of using these thick steel pipes to convert them into artillery.

Liu Sheng knew how to make muskets, and had even practiced it many times before traveling through time, but he had never made a cannon. He only knew the principles of some old-fashioned artillery.

So, he found the information about the Tiger Crouching Cannon from the Ming and Qing Dynasties, and according to the specifications, he sawed off these two 70-centimeter thick steel pipes and took the iron workshop to make trial products.

He saw that during the Ming and Qing Dynasties, there was a squatting tiger cannon with a length of two feet and an inner diameter of two inches. It was already considered the largest caliber among the squatting tiger cannons - its live ammunition range could reach one mile, which was comparable to some small-caliber red barbarian cannons. Compared.

In the Ming and Qing Dynasties, the two inches should be less than 7 centimeters, but it would be too short.

Therefore, his expectation for these two tiger squatting guns is that the longest range can reach more than one mile, and the effective range in actual combat can reach more than 300 meters.

As for the artillery with a longer range and greater power, he did not have real artillery craftsmen under his command. He only had theory but no practice. He was afraid that if he failed to build it, it would be self-defeating. Not to mention scrapping the steel pipe, it would also cause death and injury to the craftsmen.

It's better to play it safe and build ten mediocre Crouching Tiger Cannons.

At Liu Sheng's request, the blacksmiths first used bronze pouring to wrap the back seals of the two steel pipes. The back seals were three centimeters thick, forming a bronze ball about 12 centimeters in diameter at the tail of the cannon.

Then the blacksmiths were asked to wrap the joint between the bronze and steel pipes with iron sheets and put three iron hoops on them.

As for the fire door, Liu Sheng had already drilled a hole in the steel pipe and put on a simple fire door with a cap.

This can not only prevent rainwater from entering the gun bore through the ignition hole, but also have a certain blocking effect on the airflow leaking through the ignition hole.Even if the effect is average, it is still better than leaving the ignition hole exposed.

Ignition also uses the simplest method - primer and fuse.

Like cord-type ignition, breech-loading guns with breech blocks, rifled guns, explosive shells, etc., Liu Sheng planned to study them later...
Because the actual work was not complicated, Liu Sheng and several blacksmiths modified two 7cm-caliber and 70cm-long tiger squatting cannons in just one day.

Seeing that it was not dark yet, Liu Sheng took him directly outside the iron workshop to test the cannon.

After loading the propellant and the stone bullets wrapped in linen cloth, he used a special thin iron rod to penetrate the propellant package through the fire door, inserted a meter-long fuse and ignited it. Liu Sheng quickly ran to 30 Squat down in a pit dug meters away.

This fuse burned relatively slowly, and it took dozens of seconds before the propellant was ignited.

There was only a muffled thunderous sound, and the stone bullets were fired a mile away and were blocked by rocks.

Liu Sheng used his binoculars to look at the broken stone bullets a mile away and the shallow craters made by the stone bullets on the rocks, and couldn't help but laugh happily.

"This Tiger Crouching Cannon is probably modified!"
