After seeing the power of gunpowder, the emperor pulled the man of God and refused to let go;

"Listen to the words of the king of Shenxiao, this divine thunder is still an emergency law; Could it be that the gods and men have more powerful magic weapons? Ye Jinyu didn't expect Li Yuan to actually call gunpowder weapons magic weapons, or in his heart, he really thought that this kind of divine weapon was the magic weapon of the immortal family.

You are the emperor, you are the greatest. You can call it whatever you want, but when it comes to firearms, the term "queuing up to be shot" came to Ye Jinyu's head.

Before yesterday, Ye Jinyu had never heard of the academic term of lining up to shoot, but when he was looking for gunpowder, he looked through the history of the development of muskets and learned about the very joyful tactics of line infantry.

Of course, in the eyes of modern people, the "line up to shoot" tactic of line infantry is simply a line to die, how funny it is. But in reality, it was the most advanced and practical tactic of the time, and no other tactic could be more operational.

As the saying goes, practice is the only criterion for testing the truth, and if it is only a certain general's head in a certain battle, it is indeed a joke; But in fact, this tactic lasted for four hundred years, from the sixteenth century to the nineteenth century, after the birth of rifled rear-loading guns, and was used by the generals of all European countries; It's impossible for everyone's heads to have cramps.

Ye Jinyu's education is not high, his knowledge is not wide, and his experience is insufficient; If he is allowed to come up with a new weapon or a new tactic by himself, he will definitely be blind; Commanding a war may not be as clever as the thinking of the ancients;

But Ye Jinyu can learn from it, he has a history of 1,500 years to learn from; Let's say, for example, this line infantry tactic of lining up to shoot.

What do line infantry tactics need?

Infantry who can understand military orders will be lined up.

The firing range reached two hundred meters, and the effective range of the musket was more than fifty meters.

When Ye Jinyu was searching for information, he thought that if a standard smoothbore gun was designed and produced in the Tang Dynasty, and then a group of infantry who could advance and retreat according to the sound of drums were trained to use them, wouldn't it be able to light up the tactics of queuing up to shoot, and then equipping this line of infantry phalanx with some artillery might be a good choice for the development of infantry tactics in the Tang Dynasty.

At that time, Ye Jinyu was just thinking about it, and did not plan to put it into reality. Unexpectedly, Li Yuan asked him for a more powerful gunpowder magic weapon in the next day.

Li Yuan's questioning effort, Ye Jinyu's mind turned so much, and then nodded and replied: "Of course, there are more powerful firearms, such as artillery, and firearms. "Ye Shenren originally wanted to talk about muskets, but when he thought of explaining the difference between muskets and cold weapon spears, he simply used the word gun; Guns are also firearms anyway, and they are used to hunt wild boars in rural homes.

Hearing that there were two kinds of firearms, Li Yuan immediately became energetic and said, "King Shenxiao, tell me quickly, what kind of artifact this cannon and firearm are." ”

Ye Jinyu asked first: "Your Majesty, when testing the ten-kilogram charge just now, a minister was hit by a stone, do you know?" ”

Li Yuan nodded and said: "It's the Duchy of Song, Xiao Yu, the head of the household, and Qianniuwei said that he was knocked out by the lid of the pot; Only then did the palace eunuch report that he had woken up. "Xiao Yu is a relative of Li Yuan, and he is also an old man who followed Li Yuan, today he just came to see the excitement, but he didn't expect to become the first victim of gunpowder, fortunately, he didn't die, but he was knocked unconscious.

"The test just now was just an open-air explosion, but even so, a single lid can smash a person unconscious; Your Majesty can imagine if you get a big pipe blocked at one end, stuff it with a few catties of gunpowder, and then put a fist-sized iron ball into it. Detonate the gunpowder and the iron ball will be blasted out, and you can rush out for miles and kill the enemy! This weapon is called artillery! ”

Li Yuan squinted his eyes, imagining a fist-sized iron ball rushing out of a bamboo pipe with only one side opening and the rest blocked, highlighting the image of smashing people to death for several miles. But......

"God-man, won't that pipe be blown into powder?"

I didn't expect Li Yuan to think of the situation of exploding, even if this problem happens in the 21st century, it can't be eliminated, so I can only try to avoid it. Ye Jinyu explained: "This situation is called exploding, in order to avoid this situation, you can use copper or steel with better texture to make the barrel; At the same time, the walls of the guns were thickened according to the size of the shells and the amount of charge. ”

He drew a circle of about twenty centimeters with his hand, and then said: "Let's say we have a cannon that fires a cannonball twenty centimeters in size, and to fire this cannonball five hundred centimeters away and smash through the city gate, calculate how much charge it will take." With this charge, we experimented with how thick the barrel would be so that it wouldn't blow up. ”

After comparing for a while, it didn't feel very intuitive, Ye Jinyu simply found a piece of paper and drew a sketch of the red-clothed general with his watercore pen.

Li Yuan is a smart person, as soon as Ye Jinyu explained, coupled with the ugly sketch, he understood, and thought further; Nodding his head, he said, "It's just to make the pipe thicker." If you can chisel through the city gate 500 steps away, you don't need to consume soldiers to attack the city in the future; If you use that divine thunder as an iron bullet again, it will be even more powerful. From this point of view, artillery is a magic weapon that changes the way of warfare! It needs to be built, and it needs to be built in large quantities; Siege can be used, as can defending the city. ”

Not only thought of the solid iron ball, but also thought of the flowering bomb, sure enough, he is a person who will win the world immediately, and his sensitivity to the weapon of war is not comparable to Ye Jinyu, who grew up in peacetime.

Ye Jinyu praised: "It is like this, the artillery can be used to siege the city when it is large, and the small one is also very useful. ”

As he spoke, he drew a smaller barrel and added two reels in the middle.

"In the event of a siege, it can help the army to attack the city. If you encounter a field battle with the Turks; Just turn the muzzle of the cannon to the enemy, load it with gunpowder, stuff dozens of iron eggs the size of egg yolks, and sweep the enemy like hail with one shot. ”

Li Yuan couldn't help but nod again: "This cannon is also fine!" When it is made, when it is made. Available for use by the Celestial Army. ”

According to Li Yuan's meaning, the small artillery traveled with the army, and the Tiance army was about to attack Goguryeo, with the small artillery to facilitate movement and marching, while also ensuring the siege and field firepower of the Tang army; The big artillery was left in Chang'an to defend the city; In this way, even if some people come to attack Chang'an with small artillery, Chang'an City is as stable as Mount Tai. Some people don't have to say it anymore.

Seeing that Li Yuan hadn't even seen the actual cannon and became a cannonist, Ye Jinyu had a bad taste for spoofing history, and continued: "Yes, both cannons and small cannons are needed in large quantities; Not only can it be used on land, but it can also be loaded onto a ship. With artillery on the ship, you can attack the enemy from a distance, and you don't need to jump in hand-to-hand combat during naval battles, and you can also attack the enemy's land towns and cities from a distance. ”

Li Yuan is not familiar with sailors and naval warfare, but it does not affect his association of naval warfare. If the naval division of the Tang Army used artillery, it would be a disaster for the enemy of the Tang Army. Wen Yan nodded and agreed with Ye Jinyu's statement. It's just that as the monarch of a large land power, he prefers to acquire more territory than the sea. The interest in the ocean is not as high as Ye Jinyu imagined.

With the artifact of artillery as the foundation, Li Yuan was greatly interested in the fire gun that Ye Shenren said. After understanding the role of the artillery, he immediately asked: "King Shenxiao, I already know about the artillery, but I don't know what the fire gun is?" ”

"Firebolt." Speaking of the word firecracker, Ye Jinyu always unconsciously thinks of the bird gun in his hometown. Ye Jinyu has never seen anything in Smoothbore Village, but Ye Jinyu has not only seen it, but also shot the bird with his own hands, but he didn't hit it.

Thinking to himself, he drew a spear with a wooden tray on a piece of paper.

"This gun is actually a shrunken cannon, a cannon that can be held in the hand; Its gun tube shrunk to the size of a thumb, and the projectile became soybean-to-fava bean-sized. It is composed of parts such as a barrel, a buttstock and a wrench. ”

"What can such a small cannon do?" Li Yuan was still immersed in the reverie of the giant cannon, and suddenly heard the soybean-sized projectile, and suddenly couldn't understand: "What is the benefit of the soybean projectile."

？ ”

Ye Jinyu glared and said, "Of course it's useful, it can be used to kill people and horses!" ”

Thinking that the emperor had never seen a smoothbore gun, he explained: "Because of the small charge, the firing range of this musket is not as good as that of an artillery, and it can generally have a range of 100 to 200 square paces. Your Majesty, you said that if there is a detachment of 10,000 men with a musket in their hands, when facing the enemy, they stand in three columns, and when the enemy is within a range of 100 square paces, the first column fires, and then retreats to reload; The second column stepped forward, fired the same fire, and then reloaded. The third column followed; And so on and so forth. By the time the enemy rushed to the front of the queue, it was not known how many people had died; If you add a Grape Shell cannon to the middle of the array, the lethality is absolutely amazing. ”

"It's similar to a bow and arrow, can you replace it with a bow and arrow?" Li Yuan is actually distressed about steel, cannons are very useful, and it is no problem to grit his teeth and build some cannons; But 10,000 soldiers have a small iron cannon in their hands, and Datang's iron output can't keep up; Even if a small iron cannon only uses ten catties of iron, 10,000 pieces will cost 100,000 catties of iron. Moreover, this firearm also occupies the gunpowder that consumes the artillery, which is not cost-effective.

Ye Jinyu shook his head and said, "How long does it take to train an archer?" It is estimated that it will take several years for the archers to become talented; But it is much faster to train a firecracker, and it only takes half a day to make him proficient in the use of firearms; After a month of training, he can keep up with the queue. Moreover, manpower is sometimes poor, and the physical strength of the archers is consumed quickly, and once they lose their strength, they lose their combat effectiveness; But the gunners cannot, even if the gunpowder is empty, put a bayonet on the shaft, and you can use it as a spearmen; Unlike archers, who are afraid of hand-to-hand combat. ”

As he spoke, he drew a very abstract bayonet in front of the barrel of the musket he had just drawn.

Li Yuan nodded and said, "It's feasible, but in this way, the consumption of iron is huge; I don't have so much iron to make in Datang. "It already takes a lot of iron to make a musket, and a bayonet of this length.

Ye Jinyu only remembered at this time that the steel production in this era was very small; couldn't help but be silent for a moment, and then said: "I'll go back and find out, is there a suitable way to increase Datang's steel production." ”

Li Yuan was immediately overjoyed and said, "In this way, it's hard work." "This Ye Shenren can provide some good things every time, and it won't be bad if I think I come this time.

He also said: "In the map of the world provided by King Shenxiao, there is a mineral map; It's just that this map is too big, and the location of the minerals is too general, so I don't know if Shenxiao King can provide a more detailed atlas. As soon as he finished speaking, he immediately said: "There is no hurry in this atlas, and in addition, steel and firecrackers also need to be calculated in the long run. Now that the Turkic crisis is imminent, the Shenxiao King might as well build the Shenlei first, and the rest can be postponed to wait for the Turkic affairs. "There are priorities.

Gunpowder delay lead, pig breeding and nitrate, mineral atlas, development of iron ore and iron and steel smelting technology, smoothbore gun and artillery technology; Ye Jinyu wrote down one by one on the piece of paper on which the musket cannon was drawn; Prepare some technical knowledge in this area when you go back this time.

The two didn't talk for long, and a eunuch in the palace came to urge: "Your Majesty, it's almost time, it's getting late, it's time to go back to the palace." ”
