Li Qi made a large circle throughout Hebei, and finally returned to Jinyang from Heyang via Tianjing Pass in Zezhou.

The garrisons of Zelu and the two states were transferred to Heyang and Weizhou, and the Zhaoyi Army now only has garrisons in various places, and Zhou Guangfu is not in good health, so he transferred Zhou Guangfu back to the court to recuperate, and transferred Yao Yanchou back from Qinzhou to Zhaoyi Jiedu envoy. He actually doesn't trust Yao Yanchou very much, but the Zhaoyi Army is now an empty shelf, with only a small number of city defense troops stationed, and the garrison army is not under the control of the military town, and the generals can't make waves at all.

As soon as he returned to Jinyang, Cao Xin, who was also the chief supervisor of Taifu Temple, reported to him the good news that the machine workshop set up by the ordnance supervisor in Tang Ming Huangzhuang had successfully trial-produced the kind of musket that met Li Qi's requirements.

This is the happiest news that Li Qi has heard in the past two years, and this news makes him even happier than the previous ambush of the elite of the Khitan army in the Huanghe Valley. In addition to being excited, Li Qi, who had just returned to Jinyang Palace, heard the news, and even didn't have time to go back to the harem to see the queen, so he directly asked Cao Xin to accompany him to Tang Ming Huangzhuang in Yangqu County.

Later, I heard that Wang Qiang was so angry that she threw away the teapot that had prepared tea.

As a time-traveler, the attachment and preference for firearms is unimaginable for people in this era.

In fact, the manufacture of early breech muskets is not complicated, and when the casting and forging technology plus drilling, milling and other metal processing technologies reach a certain level, it is easy to manufacture qualified breech barrels, and the strength of forged steel can basically solve the problem of explosive chambers in the powder chamber.

In the late Tang Dynasty and the Five Dynasties, there were actually three kinds of musket manufacturing technology, such as early muskets, thunder fire guns and lifting guns, but due to the wrong formula of gunpowder, the power of gunpowder was insufficient, which greatly limited the application of these early firearms in the military field.

With the purification of fire nitrate, the purification of sulfur and the use of small particles of charcoal after crushing, Li Qi has basically improved the technology of making black powder to a very high level. Otherwise, in the practice of several wars, some gunpowder products used by the pro-guard forbidden army would not have played a great role on the battlefield.

Li Qi always doubted whether the breech musket could have the upper hand in the confrontation with the bow and crossbow, so when he put forward the requirements for the development of the musket, he directly asked for the development of the breech musket.

Although there are sketches of the so-called trap-type gunpowder breech rifle provided by him, due to the limitations of the milling, rifling, drilling, and cutting processing techniques of the rifle, it took two years to develop the pire-type bolt machine alone. Later, after the test firing, Li Qi asked that the flint be changed to use a red phosphorus fire cap for ignition, and once again the successful development of the musket was postponed for more than a year.

Unlike the barrels of guns in other worlds, which were still made out of iron rolls until the Age of Discovery, the Tang Army's arsenal workshop in Tang Ming Huangzhuang started very high, and from the beginning it was using forged steel to make barrels. Due to the existence of hydraulic forging machines plus hydraulic drilling machines, rolling mills, milling machines and other hydraulic machinery, the barrel is a seamless steel pipe directly drilled out of the cylindrical steel rod forged and rolled, that is, the finishing of the inner wall of the barrel also needs to be slowly cut out by craftsmen with a hand-cranked milling cutter.

After having a forging machine and a rolling mill, the process of making seamless pipes is not complicated, that is, the cylindrical steel forged and rolled out is heated again, and then placed on a large drilling machine for drilling. Fortunately, the caliber of black powder rifles is relatively large, and the requirements for drill pipes are not as high as those made in the manufacture of small-caliber rifles in later generations.

Iron and fire are the direction of development of this world.

The progress of science and technology is driven by both manpower and money, and it is not difficult for Li Qi, who owns a steel factory, a machine metalworking workshop and a gunpowder making workshop, to make muskets. In fact, in the past few years, the teachers and students of Jinyang Academy have developed more than a dozen types of muskets with not low power in the iron workshop, but because Li Qi is very picky, they have not been put into production.

In the backyard of the Huangzhuang Iron Workshop in Tang Ming, there is a specially opened firearms test field, close to the back mountain of Lanyu. This large area is sealed off with a courtyard wall, and personnel are not allowed to move in it at will to avoid accidents. After Li Qi, accompanied by Cao Xin, arrived at the Tang Ming Iron Workshop, he didn't care about resting, so he rushed to this weapon test site with great interest.

Xu Zhan and Li Tingshou, who had graduated from Jinyang Academy and became teachers of the academy, were in charge of the musket project, and after hearing the news that the emperor had personally come to inspect the school, they had already taken some students and craftsmen and several newly developed muskets to wait at the edge of the firearms test range.

Li Qi comes here several times a year to make rounds, and most of these people are very familiar with them.

"The student has seen Your Majesty!" Xu Zhan and Li Shouting led a few students from Jinyang Academy to salute, and when the students of the academy saw Li Qi, they usually bowed between teachers and students, rather than the kind of bow between monarchs and ministers. Li Qi has been the head of Jinyang Academy until now, and nominally the students who came out of these academies are his students.

Although he has been teaching teachers and students in the academy less and less time in recent years, this mountain chief is not very qualified.

Some Confucian ministers in the study thought that the relationship between the teachers and students of the monarch and the minister was chaotic, and there was a suspicion of appointing private individuals, which was not in line with the etiquette system. It's just that the emperor likes to be the head of this academy, and the teachers and students welcome it, and these opposing voices don't play a role at all.

"No need to be polite." Li Qi waved his hand, "I heard that the rifle you developed has basically met my requirements?" Li Qi talked to the teachers and students of these academies, and was used to calling me, Cao Xin frowned when he heard it, and he was also very helpless.

People are the Son of Heaven, but they like to call themselves "I", and no one can control them, as long as they don't call themselves "Sprinkle Family" like those martial artists.

Xu Zhan took out a musket from the wooden box with his own hands, and held it in front of Li Qi with both hands: "Your Majesty, the students are fortunate to live up to their lives, and after several months of improvement and experimentation, the production of the musket has finally been completed, which basically meets Your Majesty's requirements." ”

"Oh, it feels pretty good, it's more in line with the human body."

Li Qi took the rifle from Xu Zhan's hand, which was jet-black and about one and a half meters long, because there was no anti-corrosion technology for baking blue, the surface of the barrel was not like the rifles of later generations with a layer of blue light. The barrel is made of seamless steel tubes, the barrel is straight and long, and it is fixed with bolts to the breech. There is a front sight in front of the barrel, and there is a shutter with adjustable firing range in the rear of the gun, and this kind of aiming device is equipped on the crossbow, which is a relatively mature aiming device.

The bolt is not complicated, and it is certainly not simple.

That is, the bolt is pulled back, and the gunpowder chamber machined by the forged steel column will bounce upward, making it easy to add gunpowder and bullets to it. After the charge and reload are completed, the flap is pressed down and pushed forward into the chamber integrated with the barrel, and the entire charging process is completed.

Of course, the red phosphor fire cap is fastened above the side, not behind the flap, so that the bolt can be snapped into the fire.
