At the court meeting on the second day, Li Shimin issued an order for personnel changes. Li Jing moved to the military department and was in charge of military affairs. Du Ruxuan, the former secretary of the military department, moved the head of the household department, and Sun Wuji, the chief of the original household department, was promoted to the right servant.

At the same time, the Ministry of Industry was ordered to adopt a strict secrecy system for the production of relevant weapons, and a battalion of Jinwuwei was specially transferred to guard the weapons workshop of the Ministry of Industry.

When Zhang Yunwen came to the Military Academy to arrange the work of this time period, Yan Lide of the Equipment Institute found him.

"Well, Yan Yuanwai, wait a minute, I'll arrange this bit of work first!"

Zhang Yunwen is arranging the teaching work of the college. During this period, the main teaching work of the military academy was placed on theoretical teaching and immediate combat.

Although they didn't know much about the textbooks compiled by Zhang Yunwen, those theoretical instructors still listened carefully to Zhang Yunwen's explanations, took notes, and prepared to instill these things into the minds of the college again.

This made Zhang Yunwen very helpless, who called those soldiers who could read and hyphenate very few. However, what made Zhang Yunwen feel relieved was that after this scientific expedition, more than 100 scholars came to the military academy to sign up, and when asked about the reason, without exception, it was because of Zhang Yunwen's sentence "Rather be a centurion than a scholar!" Hearing the hopeless moves of these scientific expeditions, his blood boiled, and he came to the outside of the military academy under impulse.

So Zhang Yunwen immediately recited another poem: Qinghai Changyun Dark Snow Mountain, the lonely city looks at Yumen Pass. The yellow sand wears gold armor in a hundred battles, and Loulan will not be returned if it is not broken.

With the addition of this group of scholars, the situation is gradually improving. And although the contradictions and conflicts between Confucian scholars and soldiers that Zhang Yunwen expected occurred, they were small-scale. It was much better than Zhang Yunwen expected. Later, after the coordination of the instructor and Zhang Yunwen, the two parties were able to live in peace.

I believe that in the next two years, there will be not only excellent staff officers among this batch of scholars, but also teachers who can stay in the academy to teach.

Sorted out a stack of work plans and handed them to a teacher next to him: "Well, take it to Lord Qu Tu and show it, if he signs it, you can start arranging!" ”

Qu Tutong returned to Chang'an from Luoyang as early as the winter of the first year of Zhenguan, saying that he wanted to recuperate. Now, I am basically idle, running among the students all day long, watching the students' drills.

"What is Yan Yuanwai looking for me?" Zhang Yunwen stretched his waist and got up to ask Yan Lide.

Yan Lide said with a smile: "My lord, we have done almost the work you arranged last year, and we have made dozens of those shells!" ”

Zhang Yunwen was overjoyed suddenly, and suddenly grabbed Yan Lide's hand: "Really? What Yan Yuanwai said is true? ”

Yan Lide saw Zhang Yunwen's excited appearance, and immediately said: "Whether it's true or not, adults will know when they go over and see!" ”

"Oh, yes!" Zhang Yunwen immediately walked out the door. Yan Lide behind him smiled, and followed Zhang Yunwen briskly in the direction of the equipment institute.

When I came to the equipment yard, I saw a group of people surrounding the courtyard where Master Lu was.

Zhang Yunwen entered the courtyard, and the crowd of onlookers suddenly dispersed, and Master Lu showed his head and smiled at Zhang Yunwen: "Hehe, my lord, what you asked me to do last time was made!" ”

There is no need for him to say that Zhang Yunwen has already seen a cannonball on the ground. The shell had been dismantled into several parts, the projectile and cartridge were separated, and the parts inside were placed on the ground one by one. It seems that Master Lu is talking to the craftsmen around him about the structure of this cannonball.

"How is it, Lao Lu, has this shell been fired?" Zhang Yunwen asked.

Master Lu said with excitement on his face: "Well, I let go of three cannons, two of them went off, and one shot didn't go off." Obediently, the power of the cannon is really great, as soon as the cannon goes down, it suddenly blasts out a big crater of more than a zhang, and the surroundings are as if they have been plowed, the turf flies, and a few deep marks are scraped on the ground! That's amazing, sir! ”

Zhang Yunwen was also full of excitement, and hurriedly asked, "How many cannons have been produced now?" How many shells? ”

Master Lu stretched out five fingers: "I made five cannons, and there are fewer shells, only more than twenty!" But my lord, let me tell you one thing, don't you mind! ”

Zhang Yunwen was suddenly a little puzzled: "What's the matter?" ”

Master Lu said with some embarrassment: "In order to build these five cannons and study the cannonballs, Yan Yuan's foreign household department has used almost half of this year's money, nearly 100,000 yuan!" ”

"What? 100,000! Did you melt all those copper coins into the cannon, why did you spend so much money! When Zhang Yunwen heard this number, he couldn't help but be startled, even if these cannons were all cast in copper, they wouldn't need so much!

Master Lu leaned down and picked up some small bits and pieces on the shell, such as primers, sealing caps, sealing plugs, fuses, detonators and other things, as well as some small objects that shone with a coppery metallic luster.

"Those big things like barrels and shells don't cost much, they cost copper and iron, and it's these little things and gunpowder that cost money. In order to make these little things, there are only experiments again and again, and in this way, a lot of things are scrapped! There is also gunpowder, in order to experiment with shells, only real gunpowder can be verified. And an artillery shell needs at least five catties of gunpowder, so that it is calculated that gunpowder alone uses several hundred catties. But adults, once these little things are done, you will save a lot of money by making them later! Well, my lord, why don't you go to Your Majesty and talk to us, and give us some more money! ”

Zhang Yunwen took a deep breath, his brain teaser was racing, and finally said, "Okay!" Master Lu, you have all these cannons and shells ready for me! Build me a city wall at the foot of the hillside, which is comparable to the city wall of my Tang Zhongzhou. Ten days later, I will bring your majesty and all the generals to watch you fire your cannons. If His Majesty is satisfied, then the money will come! ”

Master Lu and several other masters were immediately excited.

"Don't worry, my lord, I promise I won't disgrace you!"

Zhang Yunwen inspected the equipment yard again before leaving the investigation institute. Before leaving, he repeatedly told Yan Lide, Lu Dajiang and others that the city wall must be built as soon as possible, and mortar shells must be made as soon as possible.

Since then, Zhang Yunwen has come to the investigation institute every day to see the construction of the city wall and the production of mortar shells. Finally, on the ninth day, more than 200 people worked day and night, and finally succeeded in building a section of the city wall that was 20 zhang long and half a zhang thick. However, it is a pity that this section of the wall was built directly on the ground without a foundation.

As for Lu Dajiang's mortar shells, Zhang Yunwen drew detailed drawings, and also made firing pins, fire caps and other things for Lu Dajiang to see, and Lu Dajiang finally made a mortar shell. However, according to Zhang Yunwen's estimates, this mortar shell with a caliber of nearly 80 millimeters is estimated to be about the same as the power of the artillery shells made by the Eighth Route Army during the Anti-Japanese War, and far worse than the power of Soviet-made and American-made mortars during the Vietnam War.

Seeing that it was ready, Zhang Yunwen said to Li Shimin after a court meeting: "Your Majesty, the artillery that Weichen told you a few days ago is ready, and today the minister dares to ask Your Majesty to take a look!" ”

The generals who heard this suddenly stopped. At the beginning of the staff meeting, Zhang Yunwen tried his best to advocate artillery, but it was regarded as a joke by everyone, and now, he really asked His Majesty to watch the artillery, is he really so confident in this artillery?

So, Li Shimin took the lead, Zhang Yunwen followed, and finally followed a large group of generals and went to the Military Academy together.

"Tsk, the soldiers of this academy are vigorous in their steps, strong in their posture, and their spirits are flying, they are really elite soldiers! Hey, Zhijie, those two seem to be at home, look at the strength of the training, there is really some of your style! Li Shimin walked on the edge of the school field and saw the soldiers training on the school field at a glance. And Cheng Chumo, as a squad leader, was there to reprimand a soldier who made a mistake.

Cheng Yanjin smiled proudly: "That's it, the babies from my Cheng family are all powerful!" ”

Everyone couldn't help but roll their eyes in unison.

"Hey, Hongji, that's your family Renshi, look at that black appearance, it's a little unrecognizable!" Li Shimin was surprised to find a meritorious son.

At this time, more than 200 people quickly lined up on both sides of the school field, each holding a wooden horizontal knife, a long lance, and a bow and arrow wrapped in a cloth, and under the leadership of Liu Renshi and Cheng Chumo, they formed a formation and divided the two ends of the school field.

"Chu Mo, if you just admit defeat, and you won't let you pay back the money you owe me for the three times, what do you think?" Liu Renshi seemed to be a little uneasy about his troops, and shouted at Cheng Chu Mo at the beginning.

Cheng Chumo lowered his head and pondered for a while, shaking his head: "No, at least two more times to invite the brothers in our class to drink!" ”

Hearing the conversation between the two, Li Shimin and a group of generals immediately burst into laughter, while Cheng Yanjin, Liu Hongji and Zhang Yunwen had red faces.

Zhang Yunwen was about to speak, but Cheng Yanjin had already yelled at the school field in a thick voice: "Cheng Chumo, if you dare to admit defeat today, see how Lao Tzu will clean you up when he goes back!" ”

This voice shifted the attention of the two parties to this side, and Cheng Chumo and Liu Renshi couldn't help but laugh when they saw the battle here. I was about to salute. Li Shimin waved his hand: "You two hurry up and start fighting, the victor will be rewarded!" ”

As soon as Li Shimin's words came out, the eyes of the two parties suddenly turned red, panting like cattle, and they all stared at each other with fierce eyes.

Cheng Chu said silently: "Renshi, I won't let you today!" Brothers, rush! ”

With a wave of the horizontal knife, more than 100 people fearlessly rushed towards Liu Renshi's side.

Seeing this, Cheng Yanjin clapped his hands and said, "Okay!" is worthy of being the baby of my Cheng family, looking at the momentum, tsk, rushing, rushing to kill the past! ”

Zhang Yunwen can fully imagine that this journey is probably like this when he was biting gold and fighting, rushing to kill the past in one go!

But Liu Renshi over there was not in a hurry, only to see him raise his hand: "Bow and arrow!" ”

More than a dozen more than 30 soldiers raised their bows and shot, and the feathered arrows wrapped around the cloth fell in the charging crowd, punching white spots on some of the soldiers. Anyone with three or more white spots in his body withdrew from the battlefield.

After three rounds of shooting, a total of more than ten people on Cheng Chumo's side withdrew from the battlefield.

Seeing that Cheng Chumo was about to lead someone to rush over, Liu Renshi shouted: "Abandon the bow and form a formation!" ”

I saw the soldiers throw their bows and arrows on the ground, grab horizontal knives or long lances, three people in a group, two short and one long, two short weapons with one long weapon.

Before the formation was completely formed, Cheng Chumo had already rushed to the front of the formation, raised the wooden knife stained with white ash in his hand, and slashed it fiercely.

The scene was chaotic for a while, and Liu Renshi, who formed a formation, was killed by Cheng Chumo into the formation, dividing the three-person formation one by one, and the three-person formation was facing each other, fighting with Cheng Chumo's department with all his might. At this time, it is the courage of the individual.

After fighting nearly three incense kung fu, these guys who fought in hand-to-hand combat were exhausted and forgot to die, and finally came down, and everyone was covered with cyan scars. From time to time, the sound of soldiers fighting can be heard.

"Ouch, two dogs, you're black! Damn, I don't pay back the money I owe you! ”

"Wow, tap, tap! If you cut it again, if you cut it again, Lao Tzu won't take you over the wall! ”

……

Finally, more and more people withdrew from the battlefield, and there were three or even four knife marks on their bodies, which made Zhang Yunwen angry. When these guys usually train, they hang a white mark and have to leave the battlefield and rest.

In the end, there were only more than twenty people left on the battlefield, and they had more or less one or two white marks on their bodies. counted the number of people and found that there was one more person on Cheng Chumo's side. So Zhang Yunwen had no choice but to declare Cheng Chumo win.

The excited Cheng Chumo got carried away. He waved his hand: "Brothers, go drink in the natural habitat today!" ”

Zhang Yunwen grinned: "Brother Cheng, how can we get out?" ”

"Of course it's over the wall! He finally found himself a little too carried away, ...... he finally found himself. And Liu Renshi over there was looking at himself with a gloating look.

So, at Zhang Yunwen's suggestion, Li Shimin canceled the reward for Cheng Chu's silent class and slowly walked in the direction of the equipment institute. Leaving Cheng Chumo on the school field with a resentful face.
