A freshly baked long-barreled bronze cannon with a barrel about four feet seven long, and the entire barrel was mounted on iron wheels by means of thickened bearings.

In layman's terms, that is, in the old movie "War and Peace", the kind of artillery used by the French army can be easily dragged by four or six, or even eight pack horses.

The mobility of the entire army is simply a vital lifeline for the farming nation. The greatest strategic advantage that the steppe people have over the farming peoples is nothing more than riding the word shè.

Since the founding of the army, Li Zhongyi has always put the mobility training of the troops at the top of all kinds of training subjects, and he has never wavered.

Today's Great Zhou court, under the control of Li Zhongyi, the war horses in the northwest can be continuously imported into the Central Plains, which to a large extent weakens the mobility advantage of the Khitans.

The problem of riding is basically solved, as for the problem of shè, the two major long-range attack magic weapons that Li Zhongyi has at hand, in addition to the divine arm crossbow, the bronze cannon with an effective shè range of up to 500 meters away, and the death scythe that harvests the enemy's life.

If you do a good job, you must first sharpen your tools!

The fly in the ointment is that the development of the flintlock pistol, which Li Zhongyi personally grasped vigorously, is still progressing as slowly as a snail. One of the biggest problems is the inner chamber of the barrel and the choice of the flint firing mechanism.

As for the arquebus, the Ordnance Superintendent concentrated all his strength and produced a few samples. However, arquebuses, which are too expensive, can only be used as decorations at present, and cannot be mass-produced and popularized.

Whether it is an arquebus * gun or a flintlock * gun, the biggest problem Li Zhongyi faces, in the final analysis, is just two words: gun * tube!

Not to mention it, it takes at least four months to drill through the narrow barrel and at least six months to polish the bore, resulting in ten months to create an unsatisfactory long tube.

What's worse is that due to the poor iron-smelting technology, the only few barrels, because of the lack of strength, repeatedly exploded and injured people in the experiment.

Adding iron hoops or copper hoops on the pipe body improves the explosion-proof strength of the pipe body, but it also directly causes the drawbacks of the pipe body being too heavy, and it cannot be put into actual combat at all.

Fang Jin's plan, the only firearm that Li Zhongyi can count on is only bronze artillery.

However, although the bronze artillery is far more powerful, the disadvantages are also very obvious. When carrying bronze artillery for long distances, the weight of hundreds of catties or even thousands of catties is all pressed on the two wheels. In the event of a heavy rainstorm, the artillery wagon had to exert a lot of effort every step forward on the muddy official road.

After the bombing incident, Li Zhongyi convened the craftsmen and masters of the artillery case to have a discussion, and everyone drank tea together, knocked melon seeds, and talked freely about the fundamental reasons why the bombing occurred.

"Lord, in the humble opinion of the villain, the root cause of the explosion is probably due to the insufficient strength of the copper hoop."

Pan Yi, an old craftsman who turned over and became an official, felt the favor of Li Zhongyi as an official, he hesitated again and again, and finally decided to write out his heart.

As soon as Li Zhongyi heard this, he suddenly came to the god of jīng, as long as someone dares to take the lead in telling the truth, the following things will be much easier!

"If you have something to say, just say it." Li Zhongyi casually stuffed a handful of melon seeds into Pan Yi's hand, Pan Yi looked at the melon seeds in his hand, couldn't help but be stunned, and then burst into tears.

"With such love from the Lord, even if the villain is broken, he will not hesitate to do it." Pan Yi cried and explained, "The copper xìng is soft and brittle, and the copper hoop is used to bind the barrel, and the binding force is inevitably small......"

Li Zhongyi nodded while listening, although Pan Yi didn't know a few big characters, he was an old craftsman who had dealt with metallurgical technology all his life in the shed.

This is like the later generation of science and engineering college students, after being assigned to the factory, they know a lot of theoretical knowledge, and when it comes to doing it, they are immediately dumbfounded.

Most of the master craftsmen are illiterate, but they have more or less unique skills.

Pan Yi is a rare all-round craftsman among the masters, but he decides his fate, Pan Yi's mouth is very broken, not only likes to nag, but also often blocks his bosses.

Therefore, before Li Zhongyi entered Kaifeng City, Pan Yi was just an ordinary old craftsman. Most of the craftsmen who entered the ordnance prison at the same time as Pan Yi became his superiors.

To put it bluntly, if it weren't for Pan Yi's unique skills, which made his boss love, hate and fear, his body would have been buried in the ** grave a long time ago.

Li Zhongyi treats technicians not only generously, but also very tolerant of their stinky temper.

Since Pan Yi dared to tell the truth, Li Zhongyi did not hesitate to order: "Come on, pass on my words, reward Master Pan with twenty yuan, and use it to buy wine and eat." ”

Twenty yuan, even if it is an old craftsman who has a high income now, it is definitely not a small amount.

Pan Yi was so happy that he rubbed his hands directly and began to talk nonsense: "Thank you, thank you, thank ......you, thank

Li Zhongyi couldn't help but smile slightly, God is fair, no matter what era it is, the masters with unique skills, in most cases, have low emotional intelligence, and Pan Yi is one of them.

Chu Xiong didn't pay attention to what Pan Yi said, he kept looking around silently, secretly eliminating all kinds of potential safety hazards.

No way, Li Zhongyi likes to drill into the shed, the shed is full of all kinds of long and short tools, in case someone has a bad intention, you can do it anytime and anywhere, it is simply impossible to prevent it.

After some careful deliberation, in the end, at Pan Yi's suggestion, Li Zhongyi decided to add several rings of steel hoops to the barrel of the bronze cannon to enhance the strength and toughness of the barrel.

When he left the ordnance prison, Li Zhongyi called Li Hu to him and admonished: "Uncle Yue, an all-round old craftsman like Pan Yi, the old master, is exactly the talent we need, the more the merrier." It can be said that it is a thousand instructions, and the importance of the old craftsman has been repeatedly emphasized.

"The lord and the subordinates understand, if you do your job well, you will sharpen your tools. If the weapon is good, the soldier can shed less blood and reap more benefits. Li Hu shook out a lot of rhetoric, but in the end, he missed the stuffing in reaping more benefits, completely exposing that he and Li Zhongyi are the same kind of people, and they are both masters who can't afford to make profits early.

After breaking up with Li Hu, Chu Xiong originally thought that Li Zhongyi would return home, but unexpectedly Li Zhongyi ordered: "Go to Changchun to watch and burn a few pillars of incense." ”

Chu Xiong instantly understood in an instant, after Concubine Du left the palace, she temporarily settled in the Changchun Palace, which belongs to the royal family, and the lord wanted to see her, right?

Knowing is not knowing, and knowing is also knowing!

Chu Ambition's heart was like a mirror, but his mouth seemed to have more than a dozen locks, and he didn't even dare to say half a word.
