Five days later, in this mansion, the Liu brothers and the Han sisters held a marriage ceremony.

The guests were still there, but the gift was brought again.

Almost repeating the situation a few days ago, Zhang Yunwen stood outside to greet the important guests. And those gentlemen asked for leave to drink here all night, and Zhang Yunwen asked people to carry them back to the academy the next day. They were originally shouting about the cave room, but they had to stop because they were drunk.

In the dark night, Zhang Yunwen looked at the brightly lit house, and there were bursts of noise in several rooms. The courtyard was in a mess, and several maids brought from Zhang Yunwen's house or Nanyang were bowing their heads and cleaning.

From tonight onwards, he and his two brothers have completely separated. Touching the thin paper in his arms, Zhang Yunwen walked into a room. There is a room where the Liu brothers collect valuables. In other words, it's called a vault.

Since moving into this house, the Liu brothers have directly used this room close to the bedroom as a vault, and usually uses it as a study. However, with their level of education, the books in it are purely decorations.

Zhang Yunwen knew that his brother had a hobby of collecting things, just like the house deed in Luoyang and some valuables that Li Shimin rewarded at the beginning, they always hid in places that they thought were secret. Although Zhang Yunwen can find it quickly.

When I opened the door of the room, it was dark inside. Lighting a candle, Zhang Yunwen squatted down, felt in the wall under the desk for a while, and found an old wooden box. It is said that this box is still the money box left by Liu Tu, the father of the Liu brothers. When I opened the box, I saw a piece of paper lying inside, but it was the deed of the house, as well as a few crystal clear glass beads, and two large beads of the South China Sea with a smooth color. Zhang Yunwen took out the paper in his arms and put it in the box.

This piece of paper is the title deed of the natural home.

With this title deed, you can become a shareholder of the natural home. Although the eldest grandson and Zhang Yunwen built this natural residence together, since Li Shimin ascended the throne, the eldest grandson has clearly proposed to give up the part of the equity of the natural residence, but Zhang Yunwen still allocated a part of the profits to the shopkeeper every month and asked him to send it to the palace treasury.

And Zhang Yunwen gets nearly 100 yuan of profit from Natural House every month, and now, he put this deed into this wooden box, but he gave all the profits of 100 yuan per month to the Liu brothers. The Liu brothers are just two low-level officers, and their monthly income is limited, and they may not be able to spend such a large mansion. Therefore, Zhang Yunwen gave them the deed. Afraid that they would not accept it, he quietly put the deed into a wooden box on the wedding night.

When he had done this, he put out the candles, closed the door, and went back to his room to sleep.

On the second day, Zhang Yunwen got up early in the morning. Let the two family members take the sleeping gentlemen back to school in a horse-drawn carriage, and then walk to the lobby. There, several elders were already sitting in the middle of nowhere, waiting for the two newlyweds.

Zhang Yunwen also stood behind Wei Chigong, waiting for his brother and sister-in-law to come in. In fact, he wanted to see his brother and sister-in-law's cramped expressions later.

It didn't take long to see the four figures walking into the hall, and seeing the four of them cramped and uneasy, Zhang Yunwen couldn't help but laugh secretly.

Then a few people were next to each other to serve tea. started with Wei Chigong and his wife, then Han Shiliang and his wife, and finally Zhang Yunwen. When respecting Zhang Yunwen, the Liu brothers said: "The third brother, we know that this family business is all earned by you, without the third brother, there would be no brother today." Now that my brother lives in this house, I am really ashamed! ”

"Brother, don't say that, if it weren't for the eldest brother, second brother and Uncle Liu, maybe I would have died in Luoyang and brought it to today's events! But a mere house, is it worth more than the third child's life! Speaking of the back, it was said in a joking tone.

When the Liu brothers heard Zhang Yunwen's words, they immediately smiled and didn't say anything more, just drank the tea in their hands in one gulp!

After the tea ceremony was over, Zhang Yunwen left the two newlyweds and went to the equipment hospital to see the situation. That day, I heard Master Lu, who came to congratulate and give the gift, that the cannon had been almost cast, but Zhang Yunwen never took the time to take a look, and now that the matter here is over, he went to see the cast artillery.

At this time, the equipment academy had been moved to the academy, so Zhang Yunwen decided to go to the academy first to see the teaching progress of the academy.

Not long after he came to his office and sat down, a faculty member came in.

"Hehe, I just saw Master Zhang coming in at the school gate, so I chased after him!" The instructor laughed, "I have something important to say!" ”

"You're old Joe! If there is anything to say, just say it! ”

"Well, my lord still remembers! What I want to talk about is about the children of those heroes! A few days ago, that group of heroes left the school without permission, saying that they were celebrating your brother's wedding! It's against the rules. Well, I wonder what the adults will do with them? ”

"What, they didn't ask for leave!?" Zhang Yunwen said with some surprise.

"Yes, they left the school without permission, climbed over the wall through the big tree in the west, and left the school without permission!"

"Although they violated the school rules, remember our principle that you can't beat or scold the students! So, let them do a day of physical training and then shut down for a day! ”

The instructor surnamed Qiao nodded, and was about to go out, when Zhang Yunwen stopped him: "By the way, Old Qiao, you tell me about the recent teaching progress!" ”

"According to the training method of adults, after two months of general training, the last month was a theoretical teaching in the morning and physical training in the afternoon. Now the students' physical fitness is much better than before, running twenty or thirty miles, just slightly panting! ”

Zhang Yunwen nodded: "Well, good job!" So keep it up! By the way, have there been any fights and brawls in the school? ”

"Yes! There were a lot of incidents. After being found out, the punishment was also punished, but this fight and brawl are still repeatedly banned! My lord, tell me, what should I do? ”

"Uh...... It's better to be blocked than to be sparse. Zhang Yunwen pondered for a while and said, "In this case, let's just set up a ring competition, and let those guys with contradictions go up one-on-one to solve the contradictions!" By the way, it is necessary to formulate the corresponding rules for this ring match, such as wearing armor, not death, etc. ”

Instructor Qiao's eyes suddenly lit up: "What the adults said is very true, discuss it with all the instructors below, and formulate the charter!" ”

Out of the office, Zhang Yunwen walked along the path paved with bluestone slabs to the depths of the campus.

In the deepest part of the valley, a three-foot high wall stands. The equipment courtyard is located inside the courtyard wall.

Walking outside the gate of the wall, two soldiers stopped Zhang Yunwen.

"This is a forbidden place, please show your waist card!"

Zhang Yunwen took out a waist card to equip the head of the hospital, and the two soldiers immediately got out of the way.

Entering the equipment courtyard, you can hear the sound of "clanging" and the grinding sound of various machines from time to time. Zhang Yunwen was here for the first time and was not familiar with the terrain, so he stopped a craftsman and asked where Master Lu was.

As soon as I entered Master Lu's studio, I saw a steel cast cannon barrel. The tail of the barrel was equipped with a bolt, but it was much larger than Zhang Yunwen expected.

The barrel was just laid flat on the ground. And Lu Dajiang sat on the ground in a daze, constantly rubbing a cannonball.

Although it was a cannonball, the shape was still a little worse than the conical cannonball in Zhang Yunwen's mouth.

The sound of Zhang Yunwen entering the house woke up Master Lu, and as soon as he saw Zhang Yunwen, he immediately pounced.

"My lord, you have to tell me about my life! What exactly does this cannonball have to do to make the shape you draw? ”

Zhang Yunwen looked at this cannonball and said to Master Lu: "You cast this cannonball with steel!" Steel is hard enough, but not malleable enough, so when casting shells in the future, you can add copper, and a lot of it, so that the cast shells are guaranteed to achieve the quality you want. ”

Master Lu's eyes lit up, and he was about to try it, but Zhang Yunwen grabbed him: "Don't worry, old Lu, let's take a look at this cannon body first!" ”

walked to the side of the artillery, squatted down with Master Lu, and looked at it slowly. First he pulled the bolt, and then he took a closer look at the barrel. Zhang Yunwen found that the bolt was fixed to the barrel. Due to the addition of a large block, the center of gravity of the entire gun body is far back.

"Well, Lao Lu, have you tried this artillery?" Zhang Yunwen asked.

"Try? How to try? Master Lu asked with some confusion.

"Well, you can fill it with gunpowder, and then detonate it, and try how many pounds of gunpowder it takes to make the barrel burst! You can also fill gunpowder first, then a solid iron ball, and then try to see how far the iron ball shoots! ”

Hearing Zhang Yunwen's methods, Master Lu suddenly said: "If you try the first one, wouldn't this cannon barrel be scrapped?" ”

"If it's scrapped, it's scrapped, and it's recast to the furnace! Well, don't say anything that takes a lot of time, my lord, I have allocated a lot of manpower to you, you are using assembly line production, how much time and how much energy is needed there! ”

Hearing this, Master Lu nodded silently.

"Also, with this experience, the next time you make a cannon barrel, you will consider the problem of combining the cannon bolt and the cannon barrel, and maybe you can solve this problem!"

Master Lu smiled and said to Zhang Yunwen: "My lord, I found out at this time that in addition to being proficient in Gezhi, you are also so good at persuading people!" ”

Zhang Yunwen smiled: "Let's go, let's go out to test the gun!" With that, he slowly rolled the barrel out of the house.

"By the way, you go to the master Zhao who is in charge of gunpowder and get five packets of one pound of gunpowder, five packs of one and a half pounds of gunpowder, and three packs of two pounds of gunpowder. In addition, ask Master Zhou, who is in charge of casting ironware, to ask for a dozen iron balls smaller than the muzzle of the gun. Well, I'm going to find a wheel! Go ahead! After saying that, they waved their hands, and the two of them immediately went to find their own things.
