Qin Chuan has a new title, one named Mr. Qin.

But teaching is not his expertise, he can't continue to do it if he just persists for a few times.

Then he ran to invent a monocular.

This is something he suddenly remembered when he recalled the physics knowledge he had learned.

He planned to match all the detectives and officers with a telescope, which costs about a hundred. If the worn waste is included, a lot of glass is needed.

Nowadays, Qinchuan has some money, so it is not difficult to make this thing. If you spend some manpower and financial resources, you can always make it.

But he didn't want to do it because his craftsmen were limited and he had to invest in the fire-making equipment. Moreover, the existing technology was difficult to mass-produce glass, and it was boring to make a small amount, so it would be better to spend some money and buy it.

So, after just finished the New Year at home, Luo Wen took more than a dozen letters written by Wang Jizong to Taiyuan and Yangqu again.

Those letters were written by Wang Jizong to his classmates or friends, and asked them to help spread a message. Loufan hired scholars and various craftsmen at a high price. As long as he had a skill, he could find a job worth a lot of money in Loufan.

Loufan is still too short of talents, scholars, and all kinds of craftsmen.

After Luo Wen returned with dozens of craftsmen, a pile of glass mirrors and glass bottles of various shapes, Qin Chuan began to make telescopes.

This thing is actually not difficult. You only need two convex or concave mirrors and insert them into a copper tube according to the focus.

The difficulty is dealing with color aberration.

Early telescopes saw colorful scenery, which was very, very unclear. This is because the color difference will occur when glass refracted, and Kepler telescopes can only see inverted images.

Modern telescope lenses are glued together by two lenses of different materials and curves to achieve the purpose of dealing with chromatic aberration.

If Qin Chuan wants to make a clear telescope, he can only grind the two pieces of glass into a curve with a very high degree of matching degree like modern times, then carefully cook it, and glue it over land completely transparent fish glue to become an objective lens.

Without modern precision technology, the neutralization of chromatic aberration of lenses without modern precision, and the central viewing axis of the two bonded lenses is not at one point, and ghosting and blurring inevitably occur.

Qin Chuan scrapped a few glass bottles before finally making a barely satisfactory monocular telescope.

The lens barrel is made of two pieces of copper tubes, and the focal length between the objective lens and the eyepiece can be rotated and adjusted to achieve a distance adjustment effect within a certain range. The objective lens is a convex lens, and the eyepiece is concave and forms a positive image, but the field of view is narrow, the clarity is hard to describe, and the multiple is only about four to five times. You can see the facial features of a person's face fifty steps away, see the contours of the human body two miles away, and find moving humans five miles away.

Come to Qin Chuan, just make do with it.

But for his troops, this thing is like a treasure.

Especially Zhao Wu, as soon as he got the monocular, his hands trembled inexplicably.

After a long time, he sighed slowly and said, "If I had this thing back then, I wouldn't have had so many brothers die."

Next, Qin Chuan picked a few skillful craftsmen and taught them to polish the lenses and make a batch of telescopes according to the existing specifications.

Then he went to his martial arts lecture hall. In addition to occasionally giving Wang Jizong and others a science forum and adding some textbooks, he spent most of his time teaching lectures in the martial arts lecture hall.

His students include Luo Daniu, Li Dingliang and Liu Youzhu, Zhao Wuliao Sanqiu, Lao Huang and Shanmaoer, and other core backbones, as well as ordinary talents of the Imperial Army.

He had already compiled the highly perfect Guandi Army military rules with several backbones, and imitated the Qi family army's organization to improve the military organization. The most basic unit was a team, with twelve people in a team, with one team leader and one chef.

The three teams are one flag, the general flag is set, the three flags are one department, the hundred generals are set, the three departments are one bureau, the generals are set, the three bureaus are set, the generals are set, the three departments are set as one battalion, and the main generals are set as one.

Now we first enter the camp, trap the camp, and the Wudang camp. The four camps in the Shifang camp have only 500 people. In the future, we will gradually replenish troops until the strength of one battalion, the guards of the participating generals and the chief generals combined, reaching 3,000 people.

Qin Chuan planned to set up a new personal guard, wearing red armor and red cloaks, and called the red attendant.

The previous guard Tiger and Leopard Battalion was divided into a Javelin Cavalry Battalion, which was responsible for cover, restraining, harassing, assaulting and pursuing.

After sufficient artillery will be provided, an independent artillery battalion will be established to be responsible for fire support and attacks.

The speed of the artillery battalion is determined by the speed of the artillery manufacturing.

...

On the fifth day of the first lunar month of the sixth year of Chongzhen, the Forbidden City was outside the Huangji Gate.

Due to internal and external troubles, Chongzhen canceled the five-day holiday for civil and military officials and changed it to a two-day holiday, only on the first and second day of the Lunar New Year.

Now outside the Huangji Gate, not only are there civil and military officials standing, but also two big men with shiny heads and a rat-braided braid, namely Ashan and Torush. Among them, Ashan's expression was very calm, while Turush was like a crazy sick tiger. His hands and feet had not yet recovered after being interrupted and his hands and feet were obviously already covered with thick iron chains, but they were still showing their fierceness. He stared fiercely at Emperor Chongzhen, who was sitting on the imperial throne, and the Ming court officials around him.

There were several great generals holding golden gourds next to them, staring at Ashan and Turush unremittingly for a moment, especially the latter. Once Turush showed signs of getting up, it would go down and beat the shiny head into a rotten melon.

Fortunately, Turush couldn't get up.

Chongzhen looked at the good news in his hand, his face full of excitement and excitement.

There were four good news reports in his case, one reported by the Datong Prefecture Wang Hua. After receiving the inquiry, he learned that a group of Jiannu and the Tartars went south to attack the border wall, he personally led several garrison generals from Datong Town to come out of the pass, attacked and killed two hundred enemies, including one hundred real slaves and one hundred Tartars.

Among the remaining three letters, one was reported by Liu Wenzhong. When he heard that Qin Chuan, a hundred households in Ninghua, led his troops to the fortress to block the enemy, he led his army north to support Qin Chuan, attacked the slave thieves on the side of Qingshui River, and killed two hundred enemies, including one hundred slaves and one hundred Tartars.

Another letter was sent by the new Shanxi Xu Dingchen. When he was investigating the evidence of Qin Chuan's crimes in Lan County, he heard that Qin Chuan went north to block the enemy and predicted that the other party's return was dangerous. He urgently ordered the commander of Shanxi Du Yingtang to lead all the officials to go north to help, break the thief's anger with Qin Chuan in the Snake Bowgroove and kill 248 enemies, including 85 real slaves and 163 Tartars.

And captured the slave thief alive in the white flag of Melezhen Irgen Jueluoa Mountain, and the yellow flag of Arc Laezhen Irgen Jueluotulush.

The last letter was presented by Qin Chuan, and the content was consistent with the content of the Jie News from Liu Wenzhong and Xu Dingchen.

I have to say that Qin Chuan’s good news is very beautifully written.

The more Chongzhen looked at him, the more he became more happy, and the more excited he was.

After reading the good news, he slapped the imperial case suddenly and shouted "Okay".

Then he took a big step down Danji, came a few steps away from Ashan and Tulush Errao, and looked at the two of them excitedly.

"Who is Ashan and who is Tulush?" The excited Chongzhen pointed at the two and asked loudly.

Ashan kowtowed hard and said, "The defeated general Irgen Jueluo Ashan, kowtow to His Majesty the Emperor of Ming Dynasty."

"So you are Ashan."

Seeing that the other party was so respectful, Chongzhen became more and more excited.

"Report to His Majesty the Emperor, Ashan is willing to surrender to the Ming Dynasty and devote himself to the Ming Dynasty court, and he will die."

"oh?"

Chongzhen was stunned.

The civil and military officials around him were also in an uproar.

Since the old slave rebelled, the Ming Dynasty has not captured such a high-grade general in the Later Jin level alive, let alone surrendering.

Now that Ah Shan’s words were about to descend, they were immediately excited.

After hearing Ashan's words, Tulush looked disbelief and soon glared at Ashan again, quarreling in Manchu language.

The great general beside him hurriedly found a cloth strip to squeeze his mouth, and then he became quiet.

"Are you really willing to surrender?" Chongzhen asked again with an excited look.

“It’s true.”

Ashan nodded without hesitation and continued: "To be honest with Your Majesty, Ashan has led his clan members to the border wall of Daming twice, hoping to join the Ming Dynasty..."

Then, Ashan slaughtered Daishan's enslaves his tribe, how Amin shot his two sons to death, how Huang Taiji killed his younger brother Adahai and several nephews, and what he had twice wanted to join the Ming Dynasty but failed, and came out one by one.

Chongzhen listened carefully, and at the end, he shouted: "Okay! I have appointed you as the fifth-rank cavalry lieutenant, and appointed General Wude, and left the Ministry of War to listen to the order. I will give you three more entry into the house, twenty pieces of silk and five hundred taels of silver."

"Thank you, Your Majesty."

Ashan hurriedly lay down on the ground and kowtowed heavily.

"Okay, OK, OK, hahahaha..."

Chongzhen was in a good mood and strode to the Danqian and sat back on the imperial throne.

No one of the civil and military officials opposed this reward, but they congratulated Chongzhen on his acquisition of another good general.

Chongzhen smiled and lowered his head to think for a moment, then said, "Come on, I will reward Qinchuan, the governor of the Qianhu District of Ninghua, and was granted the title of the fourth-rank cavalry commander, and was appointed General Xuanwu, and was promoted to the right-road sergeant of Datong, and guard..."

"Report to Your Majesty."

Liu Wenzhong, who was transporting his first-level team back to Beijing, suddenly left work and interrupted Chongzhen's words.

Chongzhen's face froze and he became a little unhappy.

"Your Majesty, Qin Chuan is young and energetic, and has been a man of Meng Lang, and has repeatedly bumped into Shangguan. He is not popular with the people in Jinglelan County. I believe that although this son has made great achievements, he should not be promoted to several levels in a row, so as to avoid being impetuous and arrogant. It is better to temporarily promote him to the thousand households of Ninghua Guarding, and order him to cooperate in Ningwu Pass. It is not too late to use it after much training."

Hearing Liu Wenzhong's words, Chongzhen frowned and thought for a moment, and finally nodded: "It makes sense."

...

On the sixth day of the first lunar month of the sixth year of Chongzhen, Xuanzhen border wall and Zhangjiakou Fort.

A Fan family caravan that came out of seclusion a few years ago to buy good horses came back in a mighty manner and brought back four hundred strong war horses.

The defenders of Zhangjiakou Fort, as usual, only briefly ordered the war horses, and then smiled and took a few heavy silver bags from the Fan family's manager.

No one noticed that there were two hundred more people returning caravans.

He didn't notice that the two hundred people had rough faces and fierce eyes, and their palms were always on the hilt of the knife around their waists.

If someone looks at these people carefully, they will find that under their hats, in their ears and necks, are also bare.
