Liu Zhang has been very excited recently, and anyone who is wandering on the road will be excited when he meets the next national leader and becomes friends with him. Provided, of course, that he knows who the next leader of the country will be. So, Liu Zhang decided that he must go to the streets more when he was fine. Last time, he met Zhou Yu just for a casual walk, maybe one day he could meet Guo Jia and Zhuge Liang on the street, although Zhuge Liang seemed to be only one year old! However, Liu Zhang's decision made the children of Luoyang's family unlucky again.

After a break, Liu Zhang finished moving the military camp to the outside of Luoyang City, and Liu Hong asked him to build a military camp on the edge of the mountain. After receiving the holy decree, Liu Zhang immediately led people to Bishan to survey the terrain, and finally in a valley, he selected a base. The valley is secluded enough for 20,000 people to train in a row. It's just that how to set up a barracks in the valley is a troublesome matter!

In ancient times, the barracks were all wooden villages and tents, but Liu Zhang didn't want his barracks to be so simple. In the valley, there are all kinds of dangers, snakes, insects, rats, ants, jackals, tigers and leopards are not uncommon. If it was just a tent, it would probably make the soldiers bothered by these dangers, but if it was made of stone, the project would be too big!

Sitting in the study, Liu Zhang was holding a brush and scribbling something on rice paper, Xiao Qiao stood in front of the desk grinding ink for him, while Da Qiao was using a pair of delicate little hands to help Liu Zhang massage his temples.

"Alas!" Liu Zhang sighed, and Xiao Qiao looked at Liu Zhang, who had a sad face, and didn't know why he was a little distressed.

"Childe!" Da Qiao said weakly: "If Childe has any troubles, you can talk to our sisters." We may not be able to help you solve it, but we can listen to you. You'd feel better to say it, wouldn't you? ”

"Actually, it's nothing, I just want to build a military camp in the mountains, but I think the wooden camp is too loose, and it is easy to attract snakes, insects, rats and ants." Liu Zhang pulled Da Qiao's little hand and patted it, making Da Qiao's little face red. However, his problem is not something that Big Joe can solve.

"Alas!" Liu Zhang sighed again and said, "If only I had cement!" ”

"Cement? What is Cement? Hearing Liu Zhang's self-talk, Xiao Qiao couldn't help but ask with some curiosity.

"Cement is a building material made by mixing limestone and clay in a certain proportion... No way! Liu Zhang jumped up suddenly, startling Xiao Qiao.

"Childe, what's wrong with you?" Xiao Qiao asked tremblingly, "Did I say something wrong!" ”

"It's not!" Liu Zhang excitedly picked up Xiao Qiao and turned around, and kissed her on the cheek and said, "You are really my lucky star, you remind me like this, I think of what to do!" ”

After Liu Zhang finished speaking, he rushed out of the study, leaving only Xiao Qiao, who was flushed, and Da Qiao, who was at a loss, still stunned. They really couldn't imagine that the son, who usually keeps manners, would actually kiss Xiao Qiao. By the time he reacted, Liu Zhang had already run away.

"Sister!" Seeing Da Qiao staring at himself and smiling, Xiao Qiao lowered his head a little shyly. If Liu Zhang was still there, he would definitely say that the two of them were goblins! However, Da Qiao is quite happy, which means that Liu Zhang accepts them, at least Xiao Qiao!

Liu Zhang didn't have time to care what Qiao was thinking, he needed a kiln to burn cement and bricks. But he didn't know where to look, so Liu Zhang came to Cai Yong's house, after all, his master can be regarded as the head snake of Luoyang.

Hearing that Liu Zhang was visiting, Cai Yong knew that he had nothing to do but go to the Three Treasures Palace. For the master, Liu Zhang did not hide it, and directly explained his intention. Although Cai Yong doesn't know what cement is, he knows what brick is. Because China first had a firing method of bricks in the Spring and Autumn Period and the Warring States Period. It's just that most of the bricks at that time were used for decoration. The real use of bricks as building materials was still in the Qin Dynasty.

Cai Yong thought about it and called the housekeeper Cai Fu here, because this kind of trivial matter is usually done by the housekeeper. Hearing Liu Zhang's request, Cai Fu smiled and said: "Master, we have two kilns in our house, and they are usually useless, so why don't you lend them to the champion Hou for use?" ”

"We also have a brick kiln at home?" Cai Yong looked at the housekeeper Cai Fu with some surprise, but Cai Fu looked at him helplessly. As the head of the family, he doesn't even know what kind of property his family has, and Cai Yong is rare.

Cai Fu couldn't let Cai Yong lose face in front of his students, he smiled and said: "Master, we don't have a brick kiln in our house, that kiln is for you to fire some utensils." For example, pen washes, porcelain cups and the like. However, you later used the items given by the Emperor, and our two kilns were useless. ”

Cai Yong nodded and said, "Then give it to Zhang'er!" ”

"Then thank you, teacher!" Liu Zhang was overjoyed and said: "I wonder if there are any craftsmen in the brick kiln?" ”

"Absolutely!" Cai Fu said with a smile: "Although the master doesn't need it anymore, it's also an industry." I gave the kiln to the craftsmen so that they could be self-sufficient and save themselves from wasting resources. I heard that those two kilns don't make much, but they can barely maintain food and clothing! ”

"Steward Cai, don't worry, since I use them, I will naturally not treat them badly!" Liu Zhang said with a smile: "The master knows that under me, as long as I have the ability, I can make the best use of my talents!" ”

"Beware of the cowhide blowing up!" Cai Yong hit Liu Zhang and said: "When the time comes, I won't give face!" ”

"Master, don't worry! Apprentice doesn't dare to disgrace you, doesn't he? Liu Zhang smiled and said, "It's just bothering you!" ”

"What bother me?" Cai Yong waved his hand and said, "It should be troublesome Steward Cai, he is responsible for these things!" ”

Cai Fu saluted and said: "Master don't have to believe it, I will bring the champion Hou over tomorrow!" ”

The next day, Liu Zhang came to Cai Yong's door early in the morning, and Steward Cai had been waiting for a long time! Cai Fu took Liu Zhang to the kiln outside the city, just explained to the craftsmen, and left.

The craftsmen looked at Liu Zhang a little overwhelmed, and an old man with gray hair stood up and asked, "I don't know what the little boy wants to burn?" Some simple utensils, we are okay, if it is something with fine workmanship, please forgive the son, we are not skilled enough! ”

"Old man, do you know how to burn bricks?" Liu Zhang asked with a smile.

"Bricks?" The old man smiled and said, "Childe wants to burn other things, we may not be able to, simple things like bricks are still easy for us." ”

"Do you have clay and lime?" Liu Zhang asked again.

"We have clay, but what is lime?" The old man was a little puzzled and said, "I have lived for decades, and I have never heard of lime. ”

Liu Zhang explained carefully to the old man, and the old man suddenly smiled: "The son is talking about chalk!" ”

"Chalk?" The old man had never heard of lime, and Liu Zhang had never heard of chalk. However, the old man was simpler than Liu Zhang, he directly asked people to take out a bag of chalk, and Liu Zhang took a closer look, this chalk is also lime.

With lime and clay, and the old man could burn bricks, the materials for building the barracks would soon be ready. However, in order to be foolproof, Liu Zhang still decided to slow down first, because the military camp he wanted to build must be able to resist for at least ten years. However, Liu Zhang did not study engineering and did not understand the standards of cement. If the barracks had built a tofu scum project, and his troops had not been killed in the battle, but had been crushed to death by shoddy houses, it would have been a big loss!

Chinese have always been industrious and intelligent. Liu Zhang only came up with a concept, and within a few days, several craftsmen in the kiln had studied the formula of the cement. They assured Liu Zhang that as long as it was not man-made or a natural disaster, the houses built with cement would never collapse. Of course, this is also Liu Zhang's over-cautiousness. Even the most basic cement is stronger than the ancient mud embryo house.

Building a military camp of 20,000 people requires a lot of money. Liu Zhang had no choice but to ask Su Shuang and Zhang Shiping for money. As for the manpower, he has 20,000, and it will definitely not be enough! When Su Shuang and Zhang Shiping heard that Liu Zhang wanted money, they immediately sent someone to send him the money for selling cattle and sheep.

It took a whole month, and Liu Zhang finally made the preliminary preparations! In this month, Zhang Ren and others also subdued the 20,000 Yulin army. The 20,000 people in the West Garden, every time they stood in a military posture and learned to walk, which made the other troops ridicule. Even among the 20,000 people, there are many who are resistant. However, these people know that the training of the champion Hou must have his reasons. Gradually, in the ridicule of outsiders, the 20,000 Yulin Army began to transform! By the time Liu Zhang ordered Zhang Ren to take these people away from the West Garden, they would already be able to move like a mountain!

In the valley of the mountain, on a temporary high platform, Liu Zhang looked at the neatly arranged and motionless soldiers under the stage, and was very satisfied. However, this time he didn't call these soldiers for training, but wanted them to work as construction workers, which required mobilization, otherwise these arrogant Yulin troops would have to mutiny!

Liu Zhang was standing on the high platform, and the soldiers in the audience were also watching him. Suddenly, Liu Zhang pointed to a soldier in the first row and said, "You! Dequeue! Tell me out loud! What are you? ”

"Back to the general! We are soldiers! "When the soldiers were in the West Garden, they were trained by Zhang Ren and them, and they already knew these basic answers well.

Liu Zhang asked again: "Answer me!" What are the first conditions for a military man! ”

"Obey orders!" The voice of the pawn resounded through the valley, and Zhang Fei, who was in charge of training him, was very satisfied with his momentum.

"Good!" Liu Zhang shouted: "From today onwards, this valley is our base!" Of course, we can't just sit in the dust, so we need to build our own barracks. But I don't think those tents and wooden villages are worthy of our noble status, you say, what should we do? ”

Liu Zhang's words made the soldiers look at each other, because the other troops lived in wooden villages and tents, and they didn't know what Liu Zhang wanted to do. Zhang Ren and others, who had already been angry with Liu Zhang, immediately shouted: "Build yourself!" ”

Suddenly, all the soldiers understood that Liu Zhang wanted to build a military camp here, and it was not the kind of wooden village and tent type. In ancient times, there were only wooden structures, stone structures and adobe houses, and the soldiers did not know what Liu Zhang's plans were, and they began to feel a little apprehensive.
