"Boss Wang can live here for a while, I'll take you around, take a look at the strength of the security army, and then make a decision, I'm just worried about whether your funds are sufficient, this is a transaction involving millions of taels of silver, and I'm ready at that time, but you can't come up with the money, then I'll be busy in vain." Zhang Chu's words put Wang Jijie and his army together.

"Money is not a problem, I have teamed up with several large merchants to get together millions of taels of silver." The big businessman is confident, and now Emperor Chongzhen has no way to worry about hundreds of thousands of taels of silver, he opens his mouth to be millions of taels of silver, his face does not change and his heart does not beat, it seems that this big businessman is still really rich. It shows that the fiscal policy of the Ming Dynasty was a complete failure, and the state could not effectively collect taxes, which led to financial bankruptcy, and the country's army had no pay to pay, which was also a reason for the final demise of the Ming Dynasty.

"That's good, let's go around Fugu tomorrow, and then look elsewhere." Zhang Chu was very happy, he didn't expect to meet such a rich and courageous businessman, if he didn't say big things, it would be a great boost to the development of the security army.

Wang Jijie said goodbye and left, Zhang Chu immediately found someone from the Statistics Bureau, assigned a task, found out the details of this Wang Jijie, and sent someone to close to monitor him.

Early the next morning, Wang Jijie came as Zhang Chu requested. Zhang Chu took him to the top of the city of Fugu first, originally Fugu was an important town on the side wall, the city wall was strong, and all kinds of defense facilities were complete. After Zhang Chu occupied this place, it was rebuilt according to the shape of a fortress, and now it has become a fortress that is easy to defend and difficult to attack.

"What do you think of Fugu City's defenses?" Zhang Chu pointed to various military facilities outside the city and said.

"The construction of this city is really different, but I don't know much about military matters." Wang Jijie has some understanding of the cities in various places, and can see that the urban defense construction of Fugu is indeed different, but he also can't understand the mystery.

"This alone I can't show the power of this defense system, this kind of city is called a fortress, you should have heard of the battle of Shenmu Ferry, there is a fortress in Shenmu Ferry that is much smaller than Fugu City, the defenders in the city are less than a thousand people, they resisted the siege of Hong Chengchou's 20,000 army, and then won time for me to lead the troops to arrive, and almost wrapped Hong Chengchou's 20,000 horses into dumplings. In that battle, the power of the fortress in defense was fully demonstrated, if I occupied Yuncheng, Yuncheng would be transformed, and the court did not have hundreds of thousands of troops to take Yuncheng back. "With the current Ming army's ability to attack fortifications, if you want to capture a fortified city, you can only use human lives to pile it up. Therefore, Zhang Chu was very confident that he would capture Yuncheng and hold it. "The city wall of Yuncheng Salt Lake is very large, if you need a lot of masonry to rebuild after the occupation, even if you have money, you can't get so many bricks and stones in a while. Wang Jijie because he wants to do business outside, he is still very concerned about the major events in the society, he heard that Hong Chengchou led an army of 20,000 to capture the Shenmu Ferry, and then there were various legends, Zhang Chu said that he was a god. Of course, Wang Jijie didn't believe in those gods and monsters, but it is a fact that the 20,000 troops of the official army were defeated, and it is also a fact that the 20,000 people failed to capture a small castle. When passing by the Shenmu Ferry, Wang Jijie also made a special trip to see the legendary magical fortress, and now that I think about it, the shape and structure of the Shenmu Castle are indeed similar to Fugu City. Therefore, he believed that Fugu City had a super defensive ability. But the perspective of the businessman is different, Wang Jijie first thought of the materials, labor, and cost needed if the Yuncheng was renovated. "Boss Wang is really a smart person, he can find the key to the problem at once, we have to quickly occupy Yuncheng, and we must quickly carry out the transformation, according to the old way, it will definitely not work. However, I have a miraculous material that can be mixed with water like mud to make various shapes, and when it dries, it becomes harder than stone, and it is the best material for building a wall. "Zhang Chu is talking about cement.

Cement is the favorite thing of the traverser, Zhang Chu, as a loyal reader of the traversal novel, thought about getting the cement out at the beginning of his coming to the Ming Dynasty. Influenced by the novel, Zhang Chu still remembers the formula of cement, the most common Portland cement is made of limestone and clay as the main raw materials, crushed, batched, and ground to make raw meal, and then fed into the cement kiln to calcine the mature material, and then add an appropriate amount of clinker to the gypsum to grind finely.

In fact, the manufacture of cement is not so simple, and a large number of craftsmen produced the first samples according to Zhang Chu's recipe. Everyone didn't know what the use of this thing named cement by Dashuai was, and they didn't know if it could meet Dashuai's requirements, so they sent the sample to Zhang Chu. Zhang Chu happily added water and made a pile, and then made the cement into a few bricks. A few days later, the cement dried, Zhang Chu wanted to show everyone how hard the cement was, but reality slapped Zhang Chu in the face again, Zhang Chu just picked up the dried cement brick, and the cement brick broke in his hand. This kind of strength is useless at all, it is better to just find some dirt and use water and build something stronger than this.

Zhang Chu was not discouraged and continued to invest money and personnel in the cement plant. Unexpectedly, it took two years to produce cement that was a little stronger than the first batch of samples, but it still did not meet the practical requirements. It wasn't until recently that craftsmen made hydraulic grinders to grind the raw materials used in production more finely, and the strength of the cement produced made a big leap forward, and it could be used to build castles.

However, Zhang Chu was not in a hurry to build the city with cement, but used cement to build the campus of Baoan University. Now that the school building is under construction, it is just right for Wang Jijie to see how these fine powders are turned into hard building materials. So Zhang Chu continued: "Let's go, let's go to the construction site of the Security University and see how this thing I call cement has become harder than stone." ”

"There is such a miraculous thing in the world, I don't know where it was made." Wang Jijie thinks that there are really some capable people under the hands of this anti-thief.

"I invented this cement, and of course the success of manufacturing depends on the efforts of craftsmen." Zhang Chu unceremoniously gave the invention of cement to himself.

"Dashuai is really a genius, and he has been involved in everything." I heard that cement was invented by Zhang Chu, Wang Jijie's expectations for cement have decreased a lot, a person can't know everything, there are too many magical legends about Zhang Chu, they all say that Zhang Chu invented a lot of things, but how can a thief understand the principle of so many affairs, and he can also make things with his own hands, this is simply against the sky. "Let's go to the security university and show you how miracles can be done with cement." Zhang Chu decided to let Wang Jijie feel the power of this technology. (To be continued.) )
