Cao Wenzhao was really powerful, and he only trained with the army for a few days before he met Yang He's training requirements. Moreover, Cao Wenzhao's martial arts are strong, and in several battles that Yang He deliberately arranged, Cao Wenzhao knocked out his opponent in three or two rounds, and soon Cao Wenzhao gained prestige in the new army.

However, Cao Wenzhao's soldiers did not meet Yang He's requirements until a month later.

Yang He was also very helpless about this, Yang He knew that it was not the soldiers under Cao Wenzhao who could not do it, the main reason was that Yang He's training methods were very different from the training methods of the original Ming army, and these soldiers thought that Yang He's training methods were useless, so they were resistant to such training.

Fortunately, at the urging of Cao Wenzhao, these soldiers finally accepted Yang He's training methods.

And a month later, when Yang He sold the second batch of salt, he finally had the capital to recruit troops again.

This month, the salt farm boiled more than 1,000 taels of salt and sold it for 50,000 taels of silver, excluding 5,000 taels of silver for Hei Yunhe and Zhang Mingxian, as well as various expenses, and made a net profit of 35,000 taels of silver.

With these 35,000 taels of silver, Yang He's confidence is enough.

Immediately, Yang He sent people out and recruited new recruits on a large scale. In less than a month, more than 3,000 recruits were recruited, most of whom were the children of refugees from Liaodong.

At this point, the troops under Yang He's command had reached 5,000 people, and most of these soldiers were about sixteen or seventeen years old.

Including Cao Wenzhao, many people don't understand why Yang He only recruits sixteen or seventeen-year-old teenagers, but not young people in their twenties.

You must know that the body of a sixteen or seventeen-year-old is definitely not as strong as that of a young man in his twenties, and the young man in his twenties is more mature in mind.

Yang He didn't explain it to everyone, because some things were not clear to the people at this time.

Yang He can't tell everyone. Sixteen or seventeen-year-old boys are in the period of development. It is the best time to learn and nurture. And the minds of young people in their twenties have basically been set.

In addition, Yang He can't tell everyone that he judged that Jianyu would not attack Daming in a few years, and these years were his development period, and after a few years, these teenagers had grown into young people with mature minds.

In the end, the reason why Yang He didn't explain was that he wanted to establish his absolute authority and carry out his orders whether everyone understood it or not.

Later, Yang He asked Cao Wenzhao to select young men from among the recruits who could be trained as cavalrymen. Then two cavalry battalions were formed, and since there was no official appointment from the imperial court, Yang He could only appoint Cao Wenzhao as the commander of the cavalry battalion.

Before the horses were purchased, Yang He handed over all the horses that could be used to Cao Wenzhao, so that the soldiers of the cavalry battalion could learn to ride horses.

Yang He then organized the remaining soldiers into six battalions, four of which were infantry battalions and the other two were artillery battalions.

Yang He handed over the two artillery battalions to Sun Yuanhua and asked Sun Yuanhua to teach these recruits to learn the use of artillery, but at this time, the new artillery had not yet been developed, and these recruits could only use a few tiger squat guns as learning tools.

The shabby of the cavalry battalion and the artillery battalion. The infantry battalion was no better.

In two months, the craftsman workshop in Xiangshan produced a total of more than 300 qualified guns. Most of them were unqualified, and the unqualified guns Yang He ordered all to be rebuilt.

The reason why the pass rate is too low is because the ram made by the craftsman workshop is controlled by manpower, and the manpower control ram will inevitably have deviations, but the parts of the gun are very fine, once there is a deviation, there will be one or another problem, and finally the gun can not be used.

Yang He naturally knows where the problem is, and to solve this problem, it is necessary to replace manpower with other power belts.

The only power available at this time is wind and hydro.

Among them, the limitation of wind power is very large, because whether the wind blows or not is not the final word, it depends on the eyes of God, God does not blow the wind or the wind is small, you can only stare dryly, it is not as good as manpower, after all, the use of manpower can also make some qualified components.

Compared to wind power, water power is much more reliable. Of course, it is not so easy to use water power, the flow of water must meet the requirements, and the water flow cannot generate power if the water flow is small.

However, there are many rivers in Funing County, and there are many big rivers, such as Yanghe River and Chongqing River, which all belong to big rivers, especially Yanghe River originates from Xiangshan, and the mountains and rivers converge into a lake in the west, and then flow out from the south of the lake.

The topography of the outlet in the southern part of the lake is very different, and the water of the lake flows out like a waterfall, and a pool is washed out under it, and the water in the waterhole flows all the way south into the sea, forming a river, which is the Yanghe River.

After carefully observing the flow speed of the Yanghe River, Yang He believes that the power generated by the river should be enough.

But if there is power, you have to use the power, which requires power machinery and equipment, specifically, it should be hydraulic machinery and equipment.

Under the existing conditions, it is obviously impossible to build such advanced power equipment as that of later generations.

Fortunately, Yang He did not plan to make such a mechanical equipment, Yang He only needed to build a device that could use water power to produce reciprocating motion.

Such equipment is not complicated, and the first part works in the same way as a waterwheel.

The waterwheel uses water power to drive the blades, and the blades rotate to bring water from low to high places, and the cycle repeats itself.

When the device is turned, only a connecting rod needs to be attached to the rotating shaft to generate reciprocating motion.

With a device capable of reciprocating motion, the rest is as simple as attaching the device to the bracket and driving the pressure hammer.

This equipment is actually a hydraulic stamping machine, and the structure of the whole equipment is not complicated.

Yang He led the craftsmen to build the hydraulic press in more than a month.

Of course, this hydraulic press is only an experimental product, because its main parts are made of wood, and after inspection, it is found that there is no problem, and then it is replaced with iron, so that it can be durable.

While Yang He was researching the equipment, several major events occurred in the imperial court.

On August 23 of the second year of the Apocalypse, the Emperor of the Apocalypse issued an edict to crown the emperor's younger brother Zhu Youzhen as the king of letters.

Soon after, the Emperor of the Apocalypse issued an edict to crown the imperial sister Zhu Huihui as the eldest princess of Huaiyi.

(Note: Mingguangzong has a total of seven sons, of which five sons died early, only Zhu Youxiao and Zhu Youzhen brothers, eleven women, and four daughters when they grow into adulthood, of which three daughters are married, respectively, Princess Zhu Huiyan of Ningde, mother Fu Yifei, and married Liu Youfu.) Suiping Princess Zhu Huijing, mother Fu Yifei, married Qi Zanyuan, Princess Le'an Zhu Huiyuan, mother Li Kangfei, married Gong Yonggu. Another daughter died before she was married, and the information should be Zhu Huihui, the third daughter of Mingguangzong, and the title is apocryphal. ）

In September, a major earthquake struck Shaanxi, destroying more than 11,800 houses in Guyuan, Pingliang, Longde and other counties, killing more than 12,000 people and more than 16,000 livestock.

On September 29, Xu Hongru, a rebel of the White Lotus Sect in Shandong, was captured in Tengxian County and then escorted to Beijing to be beheaded.

Although these things are big, they have nothing to do with Yang He, and what has something to do with Yang He is that Xu Guangqi resigned from his official position due to illness, and the emperor ordered him to stay idle, that is, to retain his official position and not arrange actual errands, Xu Guangqi was ready to return to Shanghai after receiving the order.

Upon learning the news, Yang He hurried into Beijing.

Yang He's entry into Beijing can be described as timely, when Yang He arrived in Beijing, Xu Guangqi had already packed up, if he came a day late, Xu Guangqi would leave.

Seeing Yang He hurriedly entering Beijing, Xu Guangqi thought that Yang He had come to see him off, and Xu Guangqi was very pleased with this.

Hearing Xu Guangqi's emotion, Yang He shook his head and smiled: "Sir, the student is not here to see off Mr., but to take Mr. to Funing County." ”

Xu Guangqi was surprised when he heard this: "When the time comes, what do you want to do in Funing County?" ”

Yang He said with a smile: "Students have always thought that it is a waste of talent to use the talents of Mr. as an official and engage in politics, and Mr. should pass on the books he has learned in his life, and then teach and educate people." ”

Xu Guangqi sighed when he heard this: "Now it is impossible to be a teacher or want to enter politics, and this time I am preparing to write a book for my teacher to return to my hometown. ”

"I wonder what the book is about, sir?" Yang He asked.

"For the teacher, I have studied agricultural policies and some agricultural techniques over the years, and I am ready to write down my experience for the teacher." Xu Guangqi said.

When Yang He heard this, he immediately knew that this book must be the world-famous "Complete Book of Agricultural Administration" in the future.

After thinking about it, Yang He continued: "Sir, as far as the students know, Mr. has also translated a book called "Geometric Originals", but it seems that the translation has not been completed, this book is very useful, and the students think that if Mr. has time, it is best to finish translating this book." ”

"Oh? Do you know Geometry Originals? Xu Guangqi said with a smile.

Yang He nodded: "The student has seen this work from Brother Chuyang. ”

Xu Guangqi smiled and said: "Chu Yang wrote me a few letters after coming to you, and I admired your ability very much, he said that your quickness of mind is far more than comparable to others, and many wonderful ideas are even more incredible. ”

Yang He smiled and said: "I just use my mouth, it is Brother Chuyang and those craftsmen who really do things, without them, even if I want to come up with flowers, I can't make weapons." ”

"You're humble." Xu Guangqi said with a smile.

Yang He smiled: "Sir, I'm really not humble. I don't hide it from my husband, as long as everyone is willing to put their minds into it, others can come up with the things I think. ”

"Hehe, I have also studied firearms as a teacher, but I don't have as many ideas as you, you won't say that you are unwilling to think about it, right?" Xu Guangqi said with a smile.

"Sir, your usual mind is useless on this!" Yang He said with a smile.

"You mean to be a teacher and not to do your job?" Xu Guangqi said with a smile.

Yang He shook his head: "Sir, if what Mr. does is also called not doing business, then I really hope that all people in Daming can do nothing." ”

After a pause, Yang He continued: "Sir, there are too few people in the Ming Dynasty who study practical learning, and Mr. should teach what he has learned to more people." ”

Xu Guangqi shook his head and sighed: "Everything is inferior, only reading is high, the purpose of reading is to be an official, including being a teacher, reading books for so many years, isn't it just to gain fame?" If you want people to learn practical learning, I'm afraid it's not so easy. (To be continued.) )
