Xuanhua Mansion City has not been so lively for a long time, since Xuanfu Town was broken by the Tartars last year, the merchants and ordinary people who live here have almost fled, and the streets of the city are almost deserted, and at this time the streets are almost full of people, not only busy Tun Guard households, but also smiling people, many shops that have been closed for a few months have also begun to open.

Since Yang Cong came, Xuanhua Mansion City has changed too much, and in less than a year, he has almost recast a Xuanhua Mansion City.

At the beginning, he moved to the north of the city and built a military factory, and everyone thought that he didn't understand anything and was fooling around, but when he led the army to defeat the Tartar cavalry with newly equipped weapons, everyone's perception of him was completely reversed, and everyone gradually believed that this governor was a powerful man, and with him, Xuanfu Town would never be attacked by the Tartars again.

At this time, the news that he led his army to defeat the Tartar cavalry had already spread, and the civilians and merchants who had moved away gradually began to move back, especially after he announced the rebuilding of the Xuanhua Military Factory, Taiyuan and even merchants near the capital rushed to hear the news.

Everyone knows that this governor is ready to do a big job in Xuanhua Fucheng, and the news that he pays military laborers has already spread throughout northern Xinjiang, nearly 20,000 laborers, nearly 20,000 taels of silver a month, these people have to spend it after getting the silver, what a big market this is, for the bottom merchants, the market of tens of thousands of taels a month is already amazing, after all, most merchants can't earn hundreds of taels of silver a year.

With the increase of merchants, Xuanhua Fucheng slowly prospered, and there was a tendency to catch up with Datong and Taiyuan in one fell swoop, and at this time, the land that was originally given to others in the south of the city and no one wanted it slowly began to become valuable, and even an acre of land rose to thirty or forty taels, which was more expensive than the cultivated land in the water towns in the south of the Yangtze River.

If other traversers come over, it is estimated that they should engage in real estate, after all, the land here was not valuable at the beginning, and Yang Cong was the governor, as long as he spent a hundred thousand taels casually, it was estimated that he could pocket ninety percent of the land in the south of the city.

However, Yang Cong didn't think about this at all, because the house prices and land prices are ridiculously low at this time, and there is no future in real estate at all.

In these years, only by doing monopoly business can he make a lot of money, such as salt, just more than 60,000 salt leads, a year is more than two million taels, if he is more greedy, secretly take out the smelted copper and iron to sell, the profit is even more amazing, and Xuanhua Fucheng even if he takes down more than 10,000 acres of land in the south of the city, a total of two or three hundred thousand taels, and it is a hammer deal, after selling this time, it will be gone, so he does not have the spare time to do this kind of "small business".

In the past few days, after he and Wang Xuan and others determined the plan of the Xuanhua Military Factory, they began to develop a new type of artillery.

The artillery of this period has the same disadvantage as the musket, that is, the loading speed is too slow, if the enemy cavalry is found to reload, there is no time to open the cannon, the enemy cavalry has already rushed to the front, and the artillery of this period is generally hundreds of pounds and thousands of pounds of giant cannons, which can not be lifted on the field battlefield at all.

After a comprehensive analysis, he finally decided to develop a rear-loading tiger squat gun, the overall weight of which was set at about 50 catties, and the shell was about the size of a fist.

This kind of artillery has never been produced before, because the power is too small, although the reloading speed of the hundreds of kilograms of giant cannons is slow, the power is still relatively terrifying, basically a cannon can plow a blood groove in the enemy's formation, at least ten casualties, and dozens of pounds of artillery can at best smash one person to death.

Of course, he knows this shortcoming, but at this time, he can't care about the problem of power, because hundreds of thousands of pounds of artillery need special artillery trucks to be pulled to the field to participate in the battle, and there are certain requirements for the terrain, like the uneven Gobi Desert outside the plug, even if there is an artillery cart, it can't be pulled, and the tiger squat cannon weighing dozens of pounds is different.

The most important problem now is the problem of not having field artillery, not the problem of lethality, if the lethality is not enough, it can be made up by quantity, and if it cannot be pulled on the battlefield, no matter how great the power is, it will be fake.

The design of this 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 he changes the front-loading type to the rear-loading type, it is almost the same.

In the past few days, he has taken advantage of his free time to draw casually, and the sketch of the tiger squat cannon has basically come out.

The tiger squat cannon he painted does not have any bells and whistles in the shape of a tiger claw and tiger head, the bracket and barrel are basically light, because this is conducive to processing, and the barrel is a whole, but the front part of the tube hole is relatively small, and the back part of the tube hole is relatively large.

He designed it this way to facilitate processing, after all, it is more troublesome to make taps and plate teeth at this time, especially like the tiger squat cannon, the thick thread of the arm, even later generations can only be processed by machine tools, and he has never seen such a large tap and plate tooth.

In this way, the structure of the whole tiger squat cannon is relatively simple, that is, the bracket, the barrel, the gun door and the shell, the bracket basically does not need how to process, it can be hooped up, the gun door is relatively simple, the large iron pin hole connected to the barrel at both ends needs to be processed, and the other places are slightly smoothed, and the barrel and shell shell need to be finely processed, basically the inner wall and the outer wall need to be processed smooth.

Fortunately, this processing difficulty is inferior to that of the musket, and the craftsmen of the Xuanhua Factory still have no problem processing it at this time, he showed the sketch to Wang Xuan, and then explained it slightly, and Wang Xuan organized people to start trial production.

The barrel of the tiger squat cannon is still made of copper, the whole is a large round pipe tail plus two small ears, there is no problem in manufacturing wooden molds, sand molds, sand casting, and the processing of the outer wall is relatively simple, but it is a little troublesome when processing the inner wall, such a big drill and reamer rotate in the barrel, the strength required is not a little bit, tossing for two days, Wang Xuan finally took someone to make the sample.

This guy, after the tiger squat cannon is made, it doesn't look like a tiger squatting on the ground, but the appearance is a bit like the mortar of later generations, however, the mortar of later generations is directly squatting on the ground, and the tiger squat cannon designed by Yang Cong must be squatted on the wooden frame, no way, because it has to be rear-loaded, if you squat on the ground, the shell can't be stuffed in from behind.

In order to test this new type of Tiger Squat Cannon, he also specially ordered someone to push a fire dragon chariot and pushed 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 when he tests in the city, the shells will fly uncontrollably to the streets or people's houses, and if the fist-sized shells hit people, it will kill people.
