Xuanhua Prefecture City has not been so lively for a long time. Since Xuanfu Town was captured by the Tartars last year, almost all the merchants and civilians living here have fled, and the streets in the city have almost become deserted. At this moment, the streets are almost everywhere, not only are there busy military households in the Tunwei, but also people with smiles on their faces. Many shops that have been closed for several months have also begun to open.

Since Yang Cong arrived, the Xuanhua Prefecture City has changed so much. In less than a year, he almost recasted a Xuanhua Prefecture City.

At first, he moved to the residents of the north of the city to build a military factory. Everyone thought he didn't know anything and was doing it randomly. However, when he led the army to defeat the Tatar cavalry with new equipment, everyone's impression of him was completely reversed. Everyone gradually believed that this governor was a powerful man. With him, Xuanfu Town would never be compromised by the Tartars again.

At this moment, the news of his army defeating the Tatar cavalry had long been spread. The civilians and merchants who had moved away gradually began to move back, especially after he announced the reconstruction of the Xuanhua Military Factory, merchants in Taiyuan and even near the capital rushed to the news.

Everyone knows that this governor is planning to do something big in Xuanhua Prefecture City, and the news that he paid military laborers has long spread throughout the northern border, with nearly 20,000 laborers, and nearly 20,000 taels of silver a month. These people have to spend it after getting the money. What a big market this is. For the lower-level merchants, the market of tens of thousands of taels a month is already amazing. After all, most merchants can earn less than 10,000 taels a year.

With the increase of merchants, Xuanhua Prefecture City gradually flourished, and it was a trend of overtaking Datong and Taiyuan in one fell swoop. At this time, the land originally given to others in the south of the city gradually began to become valuable, and even acre of land rose to thirty or forty taels, which was more expensive than the arable land in the Jiangnan water town.

If other time travelers came here, they would probably have real estate. After all, the land here was not valuable at the beginning. In addition, Yang Cong was also the governor, as long as he spent about 100,000 taels, he would probably be able to earn 90% of the land in the south of the city.

However, Yang Cong didn't think about this at all, because the housing prices and land prices are ridiculously low at this time, and there is no future in real estate. Even in Beijing, where the housing prices are the highest, a yard covering a few acres cannot be sold for hundreds of taels of silver, and it is not enough to cover a bag of salt.

Nowadays, only monopoly business can make a lot of money. For example, salt alone is more than 60,000 salt, and a year of more than 2 million taels of profit. If he is a little more greedy and secretly sells the melted copper and iron, the profit will be even more amazing. Even if he reclaims more than 10,000 acres of land in Xuanhua City, he can make a total of 200,000 to 300,000 taels, and it is a one-time transaction. After selling it, it will be gone. He has no time to do such a "small business".

His mind is now focused on the production of weapons and equipment. In the past few days, he, Wang Xuan and others have determined the planning of the Xuanhua Military Factory and started to develop new artillery.

The artillery and muskets in this period have the same disadvantage, that is, the loading speed is too slow. If you find that the enemy cavalry is loading, there is no time to fire the artillery, and the enemy cavalry will already rushed to the front. Moreover, the artillery during this period is generally large cannons worth hundreds of kilograms or thousands of kilograms, and they cannot be carried to the field battlefield at all.

After a comprehensive analysis, he finally decided to develop a rear-mounted tiger squat cannon, with a total weight of about fifty kilograms, and the shells were roughly the size of a fist.

No one has produced this kind of artillery before, because its power is too small. Although the reloading speed of hundreds or thousands of kilograms is slow, its power is still quite terrifying. Basically, a blood tank can be plowed into the enemy's formation with one shot, causing at least ten casualties. At best, a cannon weighing dozens of kilograms can kill one person.

Of course he knew this shortcoming, but he couldn't care about the power issue at this moment, because hundreds or thousands of kilograms of cannons need special cannon trucks to be pulled into the field to participate in the war, and there are certain requirements for the terrain. For example, the uneven Gobi Desert outside the Great Wall, even if there are gun cars, it can't be pulled. The tiger squat cannon weighing dozens of kilograms is different. Just put it on the carriage and you can run by pulling it with a horse.

The most important problem now is that there is no field artillery problem, not lethality. If the lethality is insufficient, you can use the number to make up, and if you cannot pull it to the battlefield, no matter how powerful it is, it will be fake.

The design of these tiger squat cannon weighing dozens of pounds is not very complicated, because he already has the prototype of the tiger squat cannon in his mind. As long as the front-mounted type is changed to the rear-mounted type, it will be almost done.

These days, he took advantage of his free time to draw casually, and the sketch of the tiger squatting cannon was basically out.

The tiger squat cannon he drew was not as fancy as the tiger claws and tiger heads. The bracket and gun barrel were basically light because it was conducive to processing. The gun barrel was a whole, but the pipe holes in the front were smaller and the pipe holes in the back were larger.

His design is also for the convenience of processing. After all, it is more troublesome to make taps and plate teeth at this time, especially like a tiger squat cannon. The threads with thick arms can only be processed in later generations with machine tools. He has never seen such a large taps and plate teeth.

In this way, the structure of the entire tiger squat cannon is relatively simple, which is the bracket, gun barrel, gun door and shell shell. The bracket basically does not need to be processed, and it can be clamped up. The gun door is relatively simple. The large iron pin hole connected to the gun barrel at both ends needs to be processed, and it needs to be polished slightly in other places. The barrel and shell shell shell need to be finely processed, and basically the inner and outer walls need to be processed smoothly.

Fortunately, the processing difficulty is worse than that of muskets. At this moment, the craftsmen in Xuanhua Factory have no problem processing. He showed Wang Xuan the sketch, and then explained it a little, and Wang Xuan organized people to start trial production.

The gun barrel of the tiger squat cannon is made of copper. The whole is a large round tube with two small ears at the tail. It is no problem to make wooden molds, sand molds, and sand casting. It is also relatively simple to process the outer wall, but it is a bit troublesome when processing the inner wall. Such a large drill bit and reamer rotate inside the gun barrel, so the effort required is not a little bit. After two days of tossing, Wang Xuan finally took someone to make the sample.

This guy didn't look like a tiger squatting on the ground after he made it. Instead, he looked a bit like a mortar from later generations. However, the mortar from later generations was directly squatted on the ground, while the tiger squat cannon designed by Yang Cong had to be squatted on the wooden stand. There was no way, because it had to be installed behind. If he squatted on the ground, the shells could not be stuffed from behind.

In order to test this new type of tiger squat cannon, he also ordered people to push a fire dragon chariot and push the tiger squat cannon outside the city.

There is no way, the range of the tiger squat cannon is not yet determined. He is afraid that the shells will fly uncontrollably to the streets or houses during the test in the city. If the shells with a big fist hit someone, it will be a life.
