Yu Wenwen saw his father ask him what the 'cement' formula and the 'wheel kiln' structure for brick making was obtained, and then he began to pretend to be crazy and stupid, he can't say that he found it on the Internet!

As an amateur author of crossing Wenpu Street, he has read a lot of information, so he knows the necessary knowledge of this kind of crossing well, and he will not admit that it is his own mastery of the soil method, cement formula and wheel kiln structure, as usual, pushed to the side of Fanshang in the Western Regions.

After the attack on Xiangyang in July last year, Yu Wenwen proposed a secret recipe, saying that the material made of a certain ratio was used as a binder for building the wall, which had a miraculous effect.

The ratio is about seventy percent of brick and tile crumble, about twenty percent of lime, and the remaining one percent is gypsum.

The three things are pulverized and mixed evenly, and stored dry, and when used, add appropriate water and stir into a slurry for use, and when it dries, it will be as solid as a rock.

Yu Wenliang, who heard this novel building material, was quite moved, and he ordered craftsmen to try out this adhesive at the same time in Xiangyang and Anlu, and it took two months to make the preliminary finished product, and the trial effect was good.

In the following months, the craftsmen adjusted the ratio and craftsmanship, and now the results are excellent, and they are also in line with the mind of Yu Wenliang, the governor of Anzhou.

The Anzhou army had a powerful siege armament, the "Cross-Era Long Range Gravity Projectile Cannon", which was able to capture the famous fortified city of Xiangyang in a few days, but the subsequent repair of the city wall was a headache.

Tearing down the city wall is fast, but then it will take a lot of manpower, material resources and time to repair it, and now the Anzhou army is always preparing to attack the Jingzhou Governor's Mansion, and it is a good thing to break the city quickly, but it is not good to repair the city wall slowly.

In the face of a large number of cavalry, the imperial army is still stronger, lest they break through the city today, and the next day the imperial cavalry will rush over and rush in from the breach, and if it falls into a war of attrition, the situation in Anzhou is not good, and the longer the war drags on, the greater the determination of Chen Guo in the south to go north.

In addition, there is a certain 'high-tech large-scale wheel kiln', as the former author of the text, Yu Wenwen shared the structure and precautions of the common brick factory wheel kiln with the craftsmen in later generations, the brick kiln of this structure produces a large amount of bricks, and uses a chimney dozens of meters high to naturally exhaust the air without an exhaust fan.

Yu Wenwen didn't want to watch the craftsmen cross the catastrophe, so he told him thousands of times: You must remember to install an iron wire on the top of the chimney to land as a lightning rod!

The craftsmen also spent nearly half a year perfecting this 'high-tech large-scale wheel kiln', and the first smoothly running wheel kiln was put into use in Xiangyang in September.

Based on its experience, an improved wheel kiln was built in Anlu in November.

Thanks to the cement and wheel kiln to make the construction cost drop significantly, Xiangyang City up and down a new repair, even the military barracks in the city began to replace with brick houses, now Anlu inside and outside the big families to the brick factory to line up to order bricks, the second brick factory after the start of construction.

Of course, Yu Wenming, who is the big owner of Xiangyang Brick Factory, and Yu Wenliang, the big owner of Anlu Brick Factory, have a lot of inputs, and Yu Wenliang found that this time since he married the third mother of the Wei Chi family in February this year, all kinds of whimsical ideas have emerged and helped him a lot.

So the boss muttered, Could it be that this kid married his daughter-in-law Wangfu?

The son is naturally happy to be a father, so Yuwen Liang is now promoting the second son Yuwen Wen after promoting the eldest son Yu Wenming, and he wants to give Yu Wenwen a place: let Yu Wenwen go to the Huangzhou Governor's Mansion to do the assassination history.

Xiyang City, Xiyang County, Bazhou Prefecture, is located near the confluence of the Yangtze River and Ba Shui, and Yu Wenliang arranged it for three reasons:

First of all, the eldest son Yu Wenming went to Xiangzhou to do the history of assassination to prepare for the future appointment of the governor of Xiangzhou, and that time the son Yu Wenwen went to Bazhou to do the history of the assassination is to prepare for the future appointment of the governor of Huangzhou.

Secondly, the current Huangzhou Governor's Mansion is east-west to the state, Huangcheng is located in the westernmost part of the entire Governor's Mansion, and Bazhou is located in the middle of the Huangzhou Governor's Mansion.

Third, Yuwenwen's title is the county duke, and his fief is Xiyang County, Bazhou, although the title of Da Zhou is false.

It is said that the governor has no right to decide the appointment of the assassins in the states under his jurisdiction, but the current set of the imperial court is not good in An, Xiang, and Huangdi, and Yu Wenming is waiting for the imperial court to make a will before taking up the Xiangzhou Assassin History, that is for the sake of a proper name, as the eldest son who will inherit the foundation of Yuwenliang in the future, of course, he must try to be as great as possible.

"The city wall of Xiyang City is broken, and my father organized manpower to repair it in August this year." Yu Wenliang also got to the bottom with his son.

"How far is the city from Longtou Mountain?" Yu Wenwen suddenly burst out with a sentence.

Yuwen Liang was very surprised when he heard this, and said How do you know that there is Longtou Mountain in the northern suburbs of Xiyang City, Yuwen Wen smiled and said Listen to others.

Xiyang County, Bazhou is the boundary of Huanggang City in later generations, the predecessor of modern Huanggang City is the Huangzhou City rebuilt at the southern foot of Longtou Mountain in the early years of Hongwu in the Ming Dynasty, he has been to Huanggang City, of course, he knows that the commanding heights are Longtou Mountain, and Xiyang City at this time should be in the southeast of modern Huanggang City.

Su Shi, the great poet of the Song Dynasty, wrote the Chibi Fu in Huangzhou (Huanggang), where there are Dongpo Chibi, and the Huanggang Middle School test paper that made him do the questions in high school.

It turned out that I was thinking too much at the time.

Yu Wenwen had no opinion on the general direction of this decision, but after thinking for a while, he put forward his own thoughts:

First of all, he had to wait for his recruits to become an army before going to work, because he didn't want to put the lives of his whole family in the hands of unreliable local county soldiers and local tyrants.

Secondly, he wanted to go to Xiyang City to see the terrain inside and outside the city, and to build a fort outside the city for his troops to be stationed and trained.

Third, in the east of the city into the Yangtze River to build a workshop, because they need to repair water wheels to use water power, if there is a naval army in Bazhou to strengthen, if not, to build a new one, one to defend against the attack of Chen Guo's water army, and the other to hold the Ba Shui estuary to protect the workshop.

Yu Wenwen has little confidence in the urban construction of Xiyang City, and decided to make a field trip, if the sanitary conditions are too poor, he must renovate it first, otherwise the family will live in it, and one day the plague will break out.

Therefore, the eldest woman Chi Chifan and the younger woman Yang Lihua can still live in Anlu City for a period of time, and then go to work with them when everything is arranged.

Yuwen Wen came out of the study, Yuwen Fifteen also finished visiting his father who was following the old manager in the mansion, and even Zhang Yu, who was also in the courtyard, and their party went to a small manor by the river on the outskirts of the city, which is the location of the glass workshop, the main source of wealth of the Xiyang County Mansion.

As the main pillar of finance, the glass workshop has a high level of secrecy, and except for Liu Caiyun, Zhang Yiman, and Hu Sanzi, no one in the 'workshop' is allowed to enter.

The production of 'glass jewelry' and glass mirrors are all done by three people.

Every time the three of them go out and go back together, the convoy is tightly guarded, because they are afraid that someone will think about it, because the intermittent appearance of 'glass jewelry' on the market has attracted the attention of people with intentions.

Most of the merchants who have some connections in Anlu Danfan know that the shopkeeper Liu of the Xiyang County Mansion has 'Western Regions Glass Jewelry' in his hands from time to time, and most of the people who do business are smart people who can't help but be suspicious of the 'source of goods', and the manor outside the city will be targeted sooner or later.

Now that the glass mirror worth thousands of pieces has come out, it is inevitable that some people will take risks, either taking advantage of Liu Caiyun and others to intercept people on the way to and from the manor, or they will rush into the manor at night to 'hunt for treasure', so Yu Wenwen decided to reuse this manor for other purposes, and moved all the original equipment and equipment to the mansion in the city.

First, there is security in the city, no one dares to attack the Xiyang County Mansion, and second, to prevent these three technicians from going in and out of being arrested, Yuwen Wen needs a lot of money to support the three of them, and there can be no accidents.

As for the raw material, river sand continues to be collected and barreled by the river near the manor, and then transported back to the city to be processed in the prefecture, so that even if someone rushes into the manor, there is nothing of value.

Mrs. Wei Chi Chifan knows the details of the workshop and knows the importance of the matter, after all, the price of glass products can maintain a high price if glass technology does not proliferate in one day, which is the largest source of income for the family.

Now all the glass-related things in the manor have been emptied, and the craftsmen on the riverside are building a waterwheel, and Lin Youdi is directing from time to time, which is the main motivation for Yuwenwen to plan as a 'machining' workshop, and this time I came to see how the progress is.

There is a river on the west side of Anlu City, called Zhuanshui (Anlu section is called Fuhe), except for some special years, the water flow is continuous all year round, so Yuwenwen built a waterwheel in the small manor, the purpose is to use the flowing water to provide power for four kinds of machine tools: drilling machine, forging machine, lathe, sawing machine.

This is also Yuwenwen's ambitious five-year plan: to make ordnance through machine tools.

The immediate goal is that the drilling machine is expected to be put into use in the next year, and the forging machine, lathe, and sawing machine are the next goals.

If you want to do a good job, you must first sharpen your tools, and he asked Lin Youdi to start making "the powerful elephant three-year improved aerodynamic Lianzhu gun" after the year, and the first problem he faced was the gun tube.

The existing two beaded gas guns are the blacksmiths with iron sheets to roll the inner wall of the potholes and uneven inner diameter is not uniform, if the water power drives the fine iron drill bit on the drilling machine to drill the solid iron rod from beginning to end can be made into the inner wall smooth diameter consistent gun pipe, and only by the drilling machine can batch to make qualified products.

This also has an advantage is to be able to make a long pipe, hand-made long pipe but also to weld the two short ones together, the quality is worrying, with a hydraulic drilling machine can also work around the clock, as long as the water does not dry up, it can continue to operate and save manpower.

At present, there is a shortage of sulfur and saltpeter for making fire, and at the same time, in order to avoid the 'spread of armaments', the flint fire gun is not considered for the time being, and Yu Wenwen decided to make Lianzhu gas gun first.

Lianzhu gas gun is currently costing hundreds of times, or pure hand-made, it takes a long time, even if it is a small batch production, the cost can not be afforded, and you have to find a way to 'technological transformation' to reduce costs.

Think of the soldiers behind him holding a series of beads of qi and firing at the enemy cavalry who sacrificed their lives to 'behead' themselves, and the scene of blood splashing people on their backs was so beautiful that it made people bubble.

Next up is the medium-term goal: boiler power.

Yu Wenwen is self-aware and does not expect to make a steam ship to conquer the world, he wants to make a usable small steam boiler as the power of the machine tool, the steam power is much stronger than the power of the water wheel.

Even if you can make a small boiler, the failure rate will not be low, if the boiler is broken on the ship, you can only look at the sky, and several sets of small boilers can be used in turn in the workshop.

With strong power and usable machine tools, production efficiency can be improved, and the goal is to eliminate the need for manpower as much as possible in the production of various armaments, such as woodworking sawing machines that can cut wooden planks efficiently, and the speed of making all kinds of wood products and naval warships can also be accelerated.

These things can't be achieved overnight, Yuwenwen asked the housekeeper Li Sanjiu to select a few reliable servants and Lin Youdi to set up a 'machining department' by him personally, insisting on burning money and expecting to complete it within a few years.

When all kinds of workshops are settled in Xiyang County, they will 'open' to upgrade their armaments, and if Anzhou and the imperial court are deadlocked and the situation is not progressing, then train the water army.

If he had the opportunity, he crossed the river and captured Wuchang County (now Ezhou, Hubei), Wuchang County, Xinzhou, Chen Guobei, on the other side of Xiyang City, because there were huge iron mines more than 40 miles further south.
