Wang Hongyu mainly brought 50 craftsmen before, absorbed dozens of Zhou family and veterans, cast the Fran machine mother cannon and tiger squat cannon, and produced 10 guns in a month.

The master brought from his uncle Liu Ruoyu instructed some skilled craftsmen to specialize in the manufacture of flintlock pistols, and planned to produce 30 pistols per month.

Zhang Mingshi once learned guns from Zhao Shizhen, and at this time provided Lu Mi gun drawings, planning to produce 20 pieces in a month.

Ordnance cannot be mass-produced, because these weapons do not make money and do not feed people.

Therefore, the amount should be moderate, at present, there are less than 300 ordnance craftsmen in total, which is already the bottleneck of the local supply of food and materials in Yunxian County, and the output will be increased when the Tuntian army lays new grain.

Yunyang, a mountainous and watery area, is just the right place to do something new~

At this time, Xu Guangqi should have been engaged in sweet potato breeding for more than ten years.

Sweet potatoes have been planted from the Americas to Luzon to Fujian and Guangdong.

However, this variety needs to be cultivated in terms of cold protection and adaptability, and Xu Guangqi has introduced sweet potatoes to the north and south of the Yangtze River to cultivate varieties that can adapt to the climate of Jianghuai.

However, the greatest effect of sweet potatoes is that they can be used in hilly, mountainous, and fertile fields in the Wasaki area.

As a staple food, it is far worse than rice, etc. In terms of land, sweet potatoes are very depleting of land fertility. In terms of diet, the proportion of energy nutrients that can be supplied is much lower than that of rice and wheat.

In short, it is not suitable for planting in fertile land, because it costs land, has average energy supply, and has average nutrition.

But there isn't much fertile land in Yunyang.

Many places are suitable for growing sweet potatoes~

The core problem in the Yunyang Mountains is the lack of transportation and suitable food crops.

Sweet potatoes just fit seamlessly.

With the excavation of water transportation potential and the improvement of land conditions, Yunxian and Yunxi have a certain amount of rice and wheat production, and Xiangyang counties are the most important grain production areas in the Ming Dynasty, which can be transported to all counties.

The staple food is still rice and flour, and sweet potatoes are an important supplement.

In this way, more soldiers can be recruited to build military camps, and the local population can be raised, and the speed of industrial development can continue to accelerate.

Wang Hongyu wrote a letter to Xu Guangqi as soon as he finished his inspection, and now he wrote back that there are a number of varieties from his hometown in Shanghai that have a slightly stronger ability to withstand the cold, and they have been tried to be planted north of the Huai River.

Now that the season of planting sweet potatoes has passed, we will be able to give a few hundred catties of sweet potato seeds suitable for planting in the Huaihe River Basin in the early spring of next year.

Yunyang belongs to the Qinling Hanshui Basin, and the sweet potato varieties that can adapt to the temperature of the Huaihe River Basin can be directly promoted in the Qinling Hanshui area.

Yunyang's population in Tuntian this year is not much, and next year is the time to plant these sweet potatoes, and in two years the sweet potatoes can be promoted again.

"Sweet potato boom"?

Wang Hongyu doesn't want that kind of false boasting.

Sweet potatoes are just one important supplement to increase utilization for different terrains.

By making use of the mountainous and hilly areas, the construction of Juntun will allow more people to engage in minerals and handicrafts in the Yunyang Mountains.

Next year, the sweet potatoes will be in place, and he sent a letter back to Xu Guangqi, striving to bring in corn, potatoes, peanuts and peppers.

All of these are suitable for planting in the area of the current layout.

Especially in Kaifeng Qi County, the peanuts produced in later generations are famous all over the world. The cash crops of Henan Province show the distribution of "peanuts in the north and sesame in the south". Now, "I signed sesame seeds, and I want peanuts too." ”

The premise of engaging in these cash crops and industrial and mining industries is that the situation must not be chaotic and there is no big shortage of grain, otherwise the market will spontaneously guide grain.

Just like the aquaculture in Huguang, it flourished before the middle of the Ming Dynasty, and the grain prices were high in the late Ming Dynasty, and the fish ponds and Hubo were filled into grain fields.

In this case, the resistance and cost of engaging in industrial and mining and cash crops are very large. Unless a highly systematic, holistic and locally adapted planned economy is adopted, the industrial and mining industries will be struggling.

Without a large number of minerals, workshops, and handicrafts, there would be no profit-seeking and reinvestment based on them, and without these reinvestments, there would be no group of scientific research personnel and no scientific research ......

Without all this, the contradictions are still intensifying over the issues of land, food, and population.

......

Yongning Toast Luxury Home and Shuixi Toast settled down, and they didn't stop during this time.

arranged for his subordinates to lurk in the surrounding prefectures and counties, bribed a group of officials to provide supplies, and recruited troops far beyond outside estimates.

The two have been preparing for decades, and finally the time has come this year.

At the beginning of the year, there was a battle between the Ming Dynasty and Nurhachi in Liaoyang and Shenyang in Liaodong, and the Ming army not only suffered huge losses, but also many Han people became slaves of Jiannu, and the two largest cities, Shenyang and Liaoyang, were lost.

What made Yu Chongming and An Bangyan even more excited was that the terrible enemies Zhou Dunji and Qin Bangping died in battle!

The Sichuan army, the Shizhu Tusi White Pole Soldiers, and the Youyang Tusi Soldiers suffered heavy losses, and Qin Liangyu, the Shizhu Tusi who he dared not face the most, also led the White Pole Soldiers to guard the Shanhaiguan.

Yu Chongming believed that the imperial court was no longer able to control the southwest Tusi, and the time was ripe for years to prepare for a rebellion.

Since the 15,000-strong Sichuan army led by Liu Wei was wiped out in Salhu two years ago, Yu Chongming felt that the opportunity to annex the southwest had come, but at that time there were only 10,000 soldiers and horses in nominally, and the main force was only 3,000.

Although he has never looked at the guards in Sichuan, he has removed 3,000 elites, and the remaining 7,000 ordinary soldiers and horses recognized by the imperial court are no different from the guards of the Ming Dynasty, and they are also farmers who have practiced a little after farming.

In the past few years, he secretly bribed a number of officials, smuggled a lot of money, secretly accumulated weapons, armor and horses, and also bought off surrounding villages and bandits.

His own army has secretly expanded by as many as 10,000 people, and now there are 20,000 troops, and if you count the people who bought them, you can have 30,000.

Before the rebellion, the maximum can reach 50,000 people.

He was very confident in his soldiers and horses, and felt that he was more powerful than the Ming army and Shuixi and other toasts.

In fact, it was just blown out, but his army was a slave, which was easier to control, and his generals were more loyal, so he had an advantage over the surrounding guards and other Tusi.

His subordinates were in a hurry, including generals Fan Long, Fan Hu, Zhang Tong, Luo Zugui, etc.; Strategists Cai Jingui, He Ruohai and others. These people expressed their submission to the imperial court on the surface, but in fact they were vigorous, building castles, enriching warehouses, and trying to strengthen the rule for a long time.

On the surface, they seem to be strict in governing the army and do not kill innocents, but in fact they are extremely fierce, thinking of grabbing more land and incorporating it into the territory of the luxury family.

Extravagant Chongming delusionally wanted to divide the southwest and claim hegemony, unite with Shuixi Tusi An Bangyan, and control Yunguichuan has great hopes.

He thinks that Shuixi Tusi has a vast land and many people, and there are 50,000 soldiers and horses on the surface, but in fact, he is secretly stationed troops like him, and it is estimated that there are almost 100,000 people.

However, there is no difference between the combat power and the soldiers of the Ming Guard, the main force of the army still relies on itself, and the conspiracy succeeds in the future, and An Bangyan is at most nominally equal to himself.

But he plans to own Sichuan, and his home is Guizhou, and he is also high in terms of the elite level of soldiers and horses.

Therefore, the luxury alliance is dominated by him.
