More than a dozen artillery pieces are concentrated together to give people an unrivaled hideous feeling, Zhao Zhen looked at the long cannon body and the thick barrel and his eyes lit up, this war monster beyond civilization is finally going to appear on the battlefield of Song Liao confrontation, maybe it can also change the mode of war.

Zhao Zhen watched the forbidden soldiers skillfully operate the artillery, clean the gun chamber, load the gunpowder, and use the pole to compact the gunpowder, and finally load the shells, this proficiency is no less than the artillery of later generations, especially how much gunpowder is used each time, there is a detailed division, the craftsman from the Ordnance Department is guided by the side, Zhao Zhen even saw the quantitative loading of gunpowder.

Walking forward, Zhao Zhen stroked the cold cannon body and asked the craftsman: "How do you judge the amount of gunpowder?" ”

The craftsman bowed down and said: "Your Majesty, the Ordnance Department has conducted detailed experiments, and the amount of gunpowder used at how far the distance is used, sometimes the more the better, the farther the projectile is sent within the scope of ability, the better, of course, it is necessary to ensure accuracy, these are all requirements, and what the supervisor said is clearer than the lower officials!" ”

Zhao Zhen looked at him in surprise and said, "So you are still an official, how many grades are you?" What is the title? ”

"Doctor Weichen Sipin Taizhong, the current artillery drill ...... of the Ordnance Division"

With the words of the craftsman, the forbidden army around took a breath of cool air, this artillery drill is the official position of teaching people to use artillery, and they can actually have the official rank of the fourth grade, this is to be said, and a group of civil servants of the imperial court will not hang themselves? !

These craftsmen did not participate in the imperial examination, nor did they have any family as a backer, but through the brains and hands to work hard, just this ability to make people look high, not to mention that the artillery loaded by others is really more accurate than their own loading, saying that they can shoot as far as they can, there has never been a discount, during this time the forbidden army has learned a lot of tricks and experience from the craftsmen.

Many gunners of the forbidden army regard this knowledge as family heirlooms, and when their children and grandchildren join the army in the future, they will not become artillerymen steadily with their father's knowledge of artillery? !

"Well, the fourth-grade Taizhong doctor is still a noble official title, the last step offends people, and the next step can't show the importance that the imperial court attaches to Gewu, no wonder the official titles that Chong Shiheng asked me for are fourth-grade officials like you."

The craftsman who fiddled with the artillery stuffed the iron cannonball into the barrel, pressed it tightly with a pusher, and turned to Zhao Zhen and said: "Official, your subordinates think that these four-grade officials are just right, so you don't have to worry about property, and there won't be too many political entanglements. ”

Zhao Zhen thought he was selling his reputation at first, but now it seems that this is really the case, because until now he has not said what his name is, but he is just a humble title such as a lower official, a micro-minister, and a subordinate, and he doesn't want his emperor to remember his name at all.

Is this the legendary scholarly spirit? Devoted to research and never put other things in his eyes, if it weren't for himself, the emperor of the Great Song Dynasty, who provided him with the needs of research, maybe this thing would not be ready to take care of himself......

It's really hard for you to get angry in the face of such a person, people are loyal to the king, is there anything wrong? Zhao Zhen seemed to be choked after eating a large piece of steamed buns, forgetting to glance at the craftsman who was constantly commanding the forbidden army, Zhao Zhen felt that it was better not to get angry in front of him.

Seventeen copper-iron alloy cannons are placed together, mightily against the Liao people's Chinese army tent, and today's artillery has been improved by the Ordnance Division The volume and strength have been much smaller, at least not as large as the original in Tokyo City, which is mainly due to the improvement of mining and smelting technology in the Great Song Dynasty, of course, it is also inseparable from casting technology.

Zeng Gongliang and Ding Du's obsession with artillery is simply to the bones, constantly experimenting with various metals, and finally under the conditions, the best way to use copper and iron is combined, the melting point of copper and iron is not very high, and the porosity problem of casting has also been overcome by them, and the cannon body of the Great Song Dynasty artillery has both strength and ductility, which is completely in line with the standards set by Zhao Zhen at the beginning.

The only problem is that the speed of manufacture is relatively slow, and it costs a lot of money, because of the difficulty of the same ferroalloy and the various problems caused by porosity, the production of a qualified gun requires at least two or three guns of materials, not to mention the manpower and material resources spent.

Zhao Zhen stroked the cold cannon body, no wonder there is a saying that the cannon is ten thousand taels of gold, this artillery does burn money, if there is no good effect, I am really sorry for my early investment, you must know that the treasury was not so abundant back then, and the money for the development of artillery came from the inner treasury......

The craftsman instructed the artillerymen in the forbidden army to observe the wind direction and speed, and estimated it, which made Zhao Zhen extremely surprised, but he didn't expect that these craftsmen of the Ordnance Department had noticed the influence of the wind on the cannonballs, and could also make a rough estimate of these effects and add them to the adjustment of the artillery.

The artillery has been adjusted, and in order to fire seventeen guns at the same time, the fuses of the guns are all made of the same material and the same length, and all the artillerymen stand on the side of the guns with torches in their hands and wait for Zhao Zhen's order.

Zhao Zhen looked at the Liao people's Chinese army tent and frowned slightly, Yelu Zongzhen, this kid dared to attack Xijin Mansion even though he knew that he was not dead, which shows that he has no fear, it stands to reason that the military strength of the two sides, how the troops, and how the equipment is, Zhang Jian, as a strategist, should know, why he did not persuade Yelu Zongzhen to find another way but really prepared to attack Xijin Mansion.

The more critical it is, the more Zhao Zhen likes to think nonsense, but time waits for no one, since the Liao people sent assassins to assassinate themselves, then I'm sorry, blood debts need to be paid in blood, you send someone to shoot me an arrow, then I can say that I can shoot you.

Zhao Zhen has nothing to shy away from, he is a pragmatist, as long as there are useful things, he will not care about anything like etiquette, with a wave of his hand, the small red flag in Peng Qi's hand shook desperately, and the seventeen artillery pieces roared all day long, and the bright fire was even more dazzling than the sun in the sky.

………………

At this time, Yelu Zhenzong was completely unaware that seventeen iron cannonballs were whistling towards him in the air, and the sound of commotion had already sounded outside the barracks, and he also heard a loud noise from the direction of Xijin Mansion, could this be the siege weapon of the Great Song Dynasty?

But what is it used for defending the city? Yelu Zong really felt that as the commander of the Great Liao, he should know the new weapons of the Great Song Dynasty, so he left his big tent.

Huluduo beside him skillfully led the emperor's imperial horse, and the emperor's habits were very clear to them, and whenever he encountered an enemy, he liked to come forward to see what was going on.

Yelu Zongzhen turned over and got on the horse, and the horse trotted forward under his control, but soon the sudden whistling sound made the horse's graceful pace become rapid, and a terrible cry like a night owl came from a distance, and it only took half a breath to cross Yelu Zongzhen's head, and finally landed on the big tent of the Chinese army that he had just left......

The tall and gorgeous imperial tent was destroyed in an instant, the white tarpaulin flew in the air, and for a while, the people and things within the imperial tent disappeared completely, and everything around the entire imperial tent seemed to be ploughed by a huge iron plow.

Even the flying dragon banner flying high and representing the emperor disappeared, as if it had been suddenly pulled out by a giant, and the entire imperial tent and even the Chinese army were torn open a huge opening, because those iron cannonballs did not stop after hitting the imperial tent, but rolled on the ground, bouncing and rushing forward, leaving traces of muddy water mixed with blood and water......

At this time, Yelu Zong really swallowed his saliva, if he came out later......
