"Shizi... Tell me, what exactly did your fifth brother spend...?"

Li Shimin finished asking.

Li Mingda, who was on the other hand, began to say: "First of all, the money for the workers' accommodation. Those workers are refugees and have no home... What should I do? My fifth brother built a house for him and lived in it for free.

Father, is this money...?"

Li Shimin nodded: "Yes, I feel that You're doing a good job in this regard. You can build a house for refugees to live in for free. It's my Li family's royal style."

"The second is wages. The elderly and children have always been consistent, and the adults have two or five stakes... Let's talk about an integer with the father. The wages of more than 3,000 people cost 3,000 to 4,000 stakes a month. The elder brother saw that he did earn 300 stakes a day.

But now it only earns more than 200 yuan a day.

A large part of the money earned went into the pockets of refugees, that is, workers.

In the end, the food was not included... My fifth brother prepared an egg for these refugees in the morning, and made pork bone or mutton bone soup at noon, and even mutton was eaten at night.

Father, the fifth brother said, we can’t lose money to those refugees, because they are all people of my Tang Dynasty and their families. Even if we don’t make money, we must place them well...!"

"Oh... If you calculate this, the fifth brother really doesn't make any money... The fifth brother eats mutton for those refugees. Father, I know that some families have recruited people some time ago, but they all recruit servants, and the best one is steamed buns. The fifth brother really invested a lot of money on these refugees." Li Zhi also said.

Li Shimin listened quietly as his two children spoke.

Following Li Shimin, he praised him and nodded and said, "It's very consistent with my heart... You'er has grown up...!"

Li Shimin's affirmation almost made Yin Fei's tears fall. At this time, Li Shimin continued: "Let's do this... Two days later, it will be my decided day for family reunion, and You'er will come in and join us...!"

"That's great... I want to sit with my fifth brother...!" Li Mingda smiled happily.

"I want to sit with my fifth brother too..." Li Zhi was not willing to be outdone.

"Brother Ninth... You are so old, you are still a boy. You actually compete with me for the fifth brother. I tell you, don't dream, the fifth brother only likes me...!" Li Mingda swore his sovereignty.

"Hmph... You have cheated Brother Wu for 20,000 yuan. I won't cheat so much, so Brother Wu will definitely like me... I can also help Brother Wu with his business... Hehe, you can't." Li Zhi smiled badly.

For a moment, Li Mingda had nothing to say, and then looked at Li Shimin on the side for help. Looking at his daughter's pitiful appearance, Li Shimin laughed: "Shizi... don't worry, your father will issue an order to make your fifth brother like you only, and you will always like it."

"Ah...!" Li Mingda cheered in surprise, then hugged Li Shimin's cheek and kissed him, "Long live Father..."

Long live this sentence made Li Shimin even happier, and that smile never stopped.

....................................................

In Dunhuafang... Li You stood by a blast furnace, and soon the fire went out, and the cement powder that was calcined and turned brown was made out.

Except for Li You, no one standing on both sides knew what the cement powder actually had.

Xue Rengui looked at the cement powder and asked Li You: "Wuron...it's all burned into powder. Are this the most solid city wall that can be built true or false...?"

"Haha..." Li You did not answer Xue Rengui directly, but said confidentiality.

You should know that this cement can certainly build the strongest city walls, not only that, it can also build houses and pavements... It can be said that it has many uses, but if cement is to play its maximum function, of course, it is still necessary to have the best companion bricks for cement.

There were already bricks in the Tang Dynasty, which were blue bricks.

Blue bricks are very good... Blue bricks have high density, no deformation, good frost resistance, oxidation, water blister resistance, wear resistance, wind and rain erosion resistance, and no corrosion for thousands of years.

Moreover, blue bricks have strong breathability and good water absorption, and can maintain indoor air humidity. The "Qin bricks and Han tiles" in ancient China can be preserved in good condition after thousands of years, which is the best proof of the excellent performance of blue bricks.

Even now, if you can find a few ancient blue bricks that are hundreds of years old, you will still feel very smooth when you touch them, and the thickness is only half that of the current bricks, but the hardness can be compared with the stones, so that this texture can be used as brick carvings.

To burn blue bricks, you must first find the right arable land. The clay layer should be thick. Generally, such land must be high arable land. After removing some of the mud on it, dig the clay and transport it to a large pond.

After adding water in proportion, the cow is driven into a large pond and trampled continuously. This is the same as the effect of constantly smashing soil to remove debris and bubbles when making clay sculptures, and enhancing stickiness.

After almost the stepping, the person jumped into the pool and stepped on it, picking up some stones he stepped on.

Don’t look at their relaxed play, if you jump into the pool, your legs will be stuck and you can’t pull them out at all.

Then put the clay into the brick mold and extrude it into molding. After drying the bricks to a specific level, they are fired in the brick kiln. After firing, water and cool it down, and stuff it into the kiln to promote the red high-priced iron oxide in the bricks to reduce the red high-priced iron oxide in the bricks to the green-gray low-priced iron oxide.

When burning the cellar, you have to stare at it day and night and can’t sleep, otherwise a sleepy will destroy the bricks of the kiln.

The blue bricks have clear edges and corners, the walls are well-built, and the white and gray joints are very beautiful. However, the clay layer of the cultivated land is only one or two meters thick, and firing the blue bricks to get clay will destroy many farmland.

So Li You didn't want blue bricks. At that time, I used blue bricks because there was no cement and the quality of blue bricks was good. The blue bricks were used, but blue bricks were expensive and damaged too much, especially for the destruction of farmland.

What brick does Li You want to use?

Of course, it is red bricks. Red bricks are not only simpler than green, but also have lower cost. The red bricks are made of red clay on the mountain as raw materials. After being crushed and mixed, they are pressed manually or mechanically. After drying, they are burned inside and out with high heat, and then turned off the heat to allow the kiln and bricks to cool.

This is OK.

Of course, red bricks are definitely not as good as blue bricks. The surface of the red bricks is bumpy and full of air holes, and it will fall off when you grab them. A truck of red bricks falls to the ground, and there are no few pieces of them with complete edges and corners. Lifting the red bricks to a height of one person, it will basically break if they fall to the ground, and falling hard by the blue bricks will only break two pieces.

So now all the folk masters who perform one-handed brick cutting are red bricks.

At this time, Li You looked at Xue Rengui and asked, "Brother-in-law... among these people, will anyone burn bricks?"

"Burning bricks..." Xue Rengui shook his head slightly and said, "I don't know much about this yet, but I'll ask later. Even if we don't have one here, there must be someone in Chang'an City who knows how to burn bricks."

"Well... brother-in-law, then you have to help me find someone who can burn bricks as soon as possible. I want to prepare a batch of bricks. When it is burned, my brother-in-law also needs to find some craftsmen who can build houses. I want to teach them to build a cement house...!"

"Cement house..." Xue Rengui looked at the cement powder that had just come out and asked, "Just use them..."

Li You laughed and said, "That's right, just use them..."
