First, we need to design hydraulic machinery and use hydraulic power to drive the rotating drill bit to drill holes.

Talent! No talent! It’s better to cultivate talents yourself! There are many things, and they are gradually progressing.

Zhao Yan gathered several carpenters and blacksmiths with outstanding skills and began to overcome problems in hydraulic applications. There are many types of hydraulic machinery.

Hydraulic mills are the simplest. When Zhao Yan mentioned them, a carpenter named Sun Er knew how to make them. Zhao Yan immediately promoted Sun Er as a foreman, who was specifically responsible for manufacturing hydraulic mills.

Hydraulic mills can be used to process grain. For Zhao Yan's biggest purpose is to produce cement. Building forts and building roads requires cement. If you use animal power to grind materials, the cost will be too high.

"How much does it cost to build a hydraulic mill?" Zhao Yan asked Sun Er.

"If it is a small one, about ten taels is enough, and it can grind hundreds of kilograms of grain a day. If it is to be made large, it will cost at least hundreds of taels of silver." Sun Eryou has made a hydraulic mill and has some understanding of the cost.

"At this time, you go and preside over the mill and build the required cement factory." Zhao Yan didn't blink. Although the investment was a bit big, the money was just a dead thing!

The function of silver is to mobilize productivity. This principle is very simple! It is no different from the stinging consumption in later generations. If no one spends money, naturally no one can make money. If people cannot make money, they will not spend money. If no one spends money, it is impossible to form market demand. Without market demand, no one will produce.

Only by allowing the money to be circulated continuously can people's productivity be fully mobilized, otherwise it will be just a bunch of waste products that can be seen but cannot be eaten.

The kingly way is to make money and gain.

As long as the hydraulic mill is used in the processing of grain and cement, it can save a lot of manpower and livestock, and people can do other things.

Although it seems not very cost-effective in the short term, it will definitely make a profit if it continues in the long term.

Then Zhao Yan led his men to study the hydraulic drilling machine. He had the drawings, but how to make the things on the drawings?

At this time, Zhao Yan discovered a problem. His craftsmen were very low in culture and could not understand his drawings and did not have standard measurement tools.

The measuring rulers used by each craftsman were different. He had no choice but to order the measurements of the Military Weapon Bureau and make a batch of rulers with the same distance.

He threw away other matters and devoted himself to the research of hydraulic drilling machines. No one could only go barefoot and began to teach his craftsmen.

The Military Weapon Bureau is currently under the charge of the Blacksmith Zhou, and Zhou Blacksmith is also under pressure. The main reason why he can become the foreman of the Military Weapon Bureau is that he is an old man from the Zhao family and can be trusted.

But his ability is his lack, so this time, Zhou Blacksmith learned very seriously in conquering hydraulic machinery and spent all day studying this area.

After teaching for more than half a month, the craftsmen from the Military Weapons Bureau finally understood the drawings. Zhao Yan then allocated 1,000 taels of silver to them to build a hydraulic drilling machine.

According to the plan, after the hydraulic drilling machine is manufactured, the flintlock rifle can be produced. Zhao Yan also drew a drawing of the flintlock rifle for the Military Weapon Bureau. The data on this drawing were studied in the institute later. The effective range of the flintlock rifle can reach 130 meters, and a three-point and one-line sight was added.

The type is a smoothbore gun. If rifled is added, the effective range can reach about 200 meters, and it has a relatively high accurate name. It is not reliable to add rifle because it is pre-loaded and the speed of applying the medicine is too slow. It is good to be able to fire twice a minute.

However, a sniper team using rifled guns can also be formed, but it cannot be popularized throughout the army.

A month after Zhao Quan went to Jinan City, he came back with a huge convoy under the escort of two servants. This time, Zhao Quan brought back the grain stored in Jinan and brought back 30,000 kilograms of iron.

Iron material has always been a shortage of the Zhao family. The Military Weapon Bureau is definitely a big iron swallower. When making weapons and muskets, they need iron materials. Each young man below needs iron materials in his hand and arrows. In addition to the manufacturing of agricultural tools, the 20,000 kilograms of iron materials he brought back last time has been almost used.

"Uncle Quan, how is the matter done?" Zhao Yan asked anxiously.

"The big merchants from the Shandong Gang have basically notified them. If they come or not, they will see them." Zhao Quan rubbed his frozen face and said, "But Zheng Shilian made it clear that he would come forward to help."

"That's good, haha! There's no need to worry about money in the future." Zhao Yan laughed.

"Honor, have you ever built the guild hall?" Zhao Quan asked.

"It has been built." Zhao Yan said. This time he asked Zhao Quan to go to Jinan and Jining to post a group of big merchants from the Shandong Gang, and sent a glass mirror, inviting them to go to the Shandong Association of Jinan on the fifteenth day of the first lunar month to discuss the sale of the glass mirror. Only the merchants from the Shandong Gang could participate.

After all, it is too troublesome to sell mirrors by yourself. It is better to ask those merchants to come to buy them and transport the supplies they need.

Most merchants in this era were in the trafficking stage and were absolutely omnipresent in trafficking. Zhao Yan needed a lot of supplies. If he bought it himself, it would be unprofitable to take up too much manpower. Using the power of these merchants is a good choice.

The Zhaojia Guild Hall is being built, mainly to receive businessmen who come to Zhaojiabao in the future.

Because the Spring Festival approaches, most of the merchants from Shandong merchants are at home, and it is mainly because Zheng Shilian takes the initiative to help.

As a leader of the Shandong Business Gang, Zheng Shilian naturally knew where the Shandong Merchants' businessmen were, so Zhao Quan sent someone to send an invitation and a mirror.

After Zheng Shilian heard that the Zhao family successfully imitated the diorama, his attitude became even more enthusiastic. After all, the Zhao family could produce dioramas and would inevitably become a climate in the future.

In addition, he will make friends with the Zhao family, and in the future, he will be able to make more money from selling dioramas.

The Spring Festival will be coming a few days later. Zhao Yan also received the Jinan City Conference of merchants. The fortification and military reform will be carried out after the first lunar month.
