After the Eastern Turks were pacified, Zhang Gong was awarded the title of Duke of Zou for his merits. Now that he has died of illness, he posthumously presented General Zuo Xiaowei with the nickname Xiang.

In a family that has not formed a family scale, it is even more difficult for children and grandchildren to take over the achievements of their fathers and grandchildren. Nowadays, there are many people in the court who are trying hard to form a family like Zhang Gongjin, but after all, there are only a few people who can get what they want.

Before leaving the hospital ward, the emperor's decree was issued, and the dynasty was dismissed for three days. A nobleman, or the death of the prince, still has to make an appearance. The old people in the court also have to attend the funeral. The boycott of the dynasty is actually the emperor's permission for officials to take a holiday, which can be regarded as a recognition of the deceased.

Li Chengqian, who returned to the East Palace, waited until the eighth day to get a notice from the palace. The emperor was going to take the ministers of civil and military affairs to test the power of gunpowder weapons. If you wait for the results of the battle, I don't know when it will take, so after Zhang Gongjin's first seven days have passed, the emperor is impatient to see the true power of gunpowder weapons.

Naturally, the demonstration of gunpowder weapons could not be around Chang'an, so Li Chengqian chose the location in the military camp led by him in Weishui. There is enough protection here, after all, important people in the Manchu Dynasty have to be present, and it is not appropriate to hurt anyone.

On the ninth day of the eighth month, on a sunny day, the emperor arrived at the personal barracks by the Weishui with the Manchu civil and military forces. Now the camp has been built with protection - a wooden house. The outside of the house was full of nailed wooden strips, and if you wanted to see the outside, you had to look out through the cracks in the boards.

The emperor was very interested in this kind of protection, and personally smashed the protection with a stone, nodded and said: "Very strong, prince, tell me, do you really want to hide in this protection and watch?" ”

Li Chengqian nodded and said, "That's right, to be honest, with such protection, Erchen still doesn't think it's appropriate." After all, a big guy was sent to the workshop this time, and if you really want to talk about the power of this guy, Erchen thinks it's more appropriate to describe it as 'breaking the city gate'. Such a weapon, even if it is far away, can be threatening. After all? The power of gunpowder weapons is reflected in the explosion? And the explosion is impossible to calculate the possibility at all? For your safety and the safety of your ministers? Erchen didn't think it was a fart to take off his pants. ”

Du Ruhui said with a smile: "His Royal Highness the Prince's words are not rough, and Weichen also thinks that it is better to be serious about protection." Your Majesty? Wechen heard that this gunpowder weapon needs to be ignited to activate, so why don't you let Wechen be the one who ignites the fire? ”

Du Ruhui finished speaking? Cheng Biting Jin came out? patted Du Ruhui's back without caring about his identity, and laughed: "Lao Du, you better forget it, just your body, be careful of danger?" My old Cheng is different? The last thing I'm afraid of is danger, so let's come. ”

Wei Zheng is now in Menxia Province and has the responsibility of supervising the behavior of hundreds of officials, so he walked out without hesitation and said: "It's just a fire, and you still need to be strong?" Don't mess around? Although everyone is not wearing official uniforms, but you pat this and pat that? What a system! ”

Wei Zheng stood up, and Cheng Yanjin could only shrink back with his head suffocated.

Is there really a lot of eldest grandson Wuji? He stood up and made a group and said, "Everyone, why don't you let the old man be the one who ignites the fire?" Stop the dynasty today? Come back to Chang'an later? How about the old man invite all his colleagues into the drunken wind building? ”

Even the words of the treat? There is really no one to fight with the eldest grandson Wuji. However, the emperor is naturally not included.

Li Shimin scratched his chin and asked Li Chengqian: "The danger is the weapon, and the act of igniting the fire is not dangerous, right?" ”

Li Chengqian nodded and said: "There is no danger in igniting a fire, if my father wants to light a fire, it is a big deal for his sons to let the fuse be pulled into the house." ”

"In that case, let's let me do some of this fire!"

Looking at the emperor who was full of interest, the eldest grandson Wuji could only keep his mouth shut. The emperor wants to grab the first, and no one dares to compete with the emperor.

On the carriage surrounded by the Forbidden Legion, several soldiers tiptoed down a huge iron box, more than a meter long, forged extremely thick, and stuffed with black powder, the fuse that showed its head was only a finger long. As long as such a weapon is used, the fuse will inevitably be connected very long, and in order to avoid the fuse from getting wet, the craftsmen simply designed the fuse to be much shorter.

Such a murder weapon was sent by the soldiers to the simulated city gate that was built in a hurry in the distance. This city gate is modeled after the city gate of Chang'an City, because the material is cement, the degree of solidity is even better.

A long fuse, extending from a distance into the protective house.

Li Shimin curiously pinched the side of the fuse to check it, and wanted to take it apart a little, but when he heard the sound of the soldiers outside being ready, he could only give up.

Wei Chigong held a huge shield and guarded the emperor's side, this was specially requested by Li Chengqian, such a weapon, it was the first time to experiment, the ghost knows how much energy it could release! When the craftsmen built the mock city wall, in order to be realistic, they did not use clay at all, but real boulders, and when the bomb is lit, these stones will become real murder weapons.

took out the fire fold from his arms, blew, Li Shimin licked his dry lips, and asked, "Just light this rope, right!" ”

Li Chengqian nodded, put on his helmet, and looked vigilantly at the simulated city wall in the distance outside. Now as long as they are there, no matter who they are, they are hiding in the building under his orders, and there should be no accidents.

Even as the emperor, Li Shimin used a lot of determination to light the fuse, pushed Wei Chigong away, and walked behind Cheng Yanjin and the others to look outside.

After seeing the prince put on the armor of his front body, as if he was facing a great enemy, the civil officials couldn't help but retreat, while Cheng Yanjin and others walked to the window without fear. There was no doubt that this gunpowder weapon was to be assembled into the army, and they were all curious about what kind of power it was, and dared to claim to surpass the Eight Bull Crossbow.

The fuze of the gunpowder, in order to avoid breaking, was made very roughly, so that you could watch a line of fire stretch from near to the bottom of the simulated city wall in the distance. When the fuse's flare was gone, the illusion appeared!

I could see that the simulated city wall swelled and collapsed in a burst of fire and smoke, but my ears did not hear any sound.

Seeing such power, Li Chengqian could only say loudly before the shock wave arrived: "Cover your ears!" Open your mouth! ”

After saying that, he did it himself.

A thunderbolt on a sunny day is not enough to describe this roar!

Obedient, such as Wei Zheng, Changsun Wuji and others, were just shocked by this movement, Cheng Yanjin and others, who were closest to the window, wanted to cover their ears It was too late, and after the roar, they all shook their heads to get rid of the tinnitus.

After the roar, it's time for the secondary damage from the gunpowder weapon.

Wei Chigong saw a big stone fall from the sky and hit the ground in front of the house, so he hurriedly blocked the shield in his hand in front of the emperor.

There is no doubt that this boulder is from that section of the city wall, and it was actually shaken here!

The hut was sturdy, but when they heard the sound of rain overhead, they were very worried, for fear that a stone would hit the roof.

Finally waited until all the movement disappeared, Wei Chigong took the lead, put the giant shield above his head, and went out to check the situation.

After making sure that no stone fell from the sky, he went into the house and told the emperor that he could come out.

By the time I walked out of the hut, the smoke had already dissipated. When the Tang monarchs and ministers saw the city wall that had become broken and ruined in the distance, they couldn't help but gasp. Although I had already heard about the results, I couldn't help but be shocked when I saw such results. The shock of fantasy becoming reality is not so easy to eliminate.

"The old man's carriage!"

Du Ruhui screamed miserably, causing everyone to look outside the field.

At this time, many of the cars parked outside the barracks suffered from the damage, not only the carriages, but also the horses pulling the carts. Their cars don't want to have a special protective house like the carriage carrying gunpowder and weapons.

"With such an artifact, in the future, my Tang army will still be afraid of any strong city and stubborn city, no matter how tall and dangerous he is, he will have to become a pile of rotten stones under this artifact!"

Li Ji waved his hand excitedly, obviously his carriage was now in tatters, but he didn't feel a little distressed. He has been in the army for many years, and he naturally knows that with such a weapon, the fortified city will no longer need to be filled with human lives. Siege of a city, there is never an easy time, what outwitting, it is an extremely rare example of war for thousands of years, and it will be widely sung. Apart from these, which time is not the height of the pile with corpses? In the most difficult times, the corpses were piled up as high as the city walls in order to achieve victory.

Now it's different, with this thing, it can destroy the enemy's walls at a small cost. Without the support of the city wall, when did the Tang soldiers ever be afraid of the intersection of white blades?

Li Jing has always been wise, he pointed to the carriage that drove out again and said: "This huge weapon is only used to break the city, and if it is made smaller, wouldn't it be able to assemble it for the whole army?" ”

Li Chengqian smiled and stretched out his thumb: "Wei Gong is right, this is only the strongest gunpowder weapon, which can only be equipped by the legion, and individual soldiers naturally have individual weapons, so I will take it out and show it to you." ”

After speaking, Li Chengqian pointed to the fire fold still in the emperor's hand and said, "Father, fire, fire." ”

Looking down at the fire fold, Li Shimin put out the fire. Now he finally understood why Ouyang Shuo claimed that his name was not suitable for the gunpowder workshop, it was because there was a word "fire" in it.

With such a powerful weapon, avoiding fire is a must!

The soldiers of the forbidden army helped the prince carry down a box together, and when they opened it, they saw that there were twenty iron eggs that could be held in one hand neatly placed inside, with strange shapes, but the fuses on them indicated that they were also murder weapons that killed people.

picked up a grenade, and even Li Chengqian couldn't help but sigh at the ability of the Tang Dynasty craftsmen.

Ouyang Shuo and others were in the gunpowder workshop, and in addition to making gunpowder, they also shouldered the responsibility of researching gunpowder. Even he didn't know how Ouyang Shuo made it, but he actually made a time-delay fuse. Don't look at the fuse inserted in the grenade is a bit short, but it takes five breaths from ignition to explosion.

The shell of the grenade is actually Li Tai's achievement. After all, this guy still became interested in gunpowder weapons, and without saying a word, he ran into the weapon making workshop to study and design the shell.

Speaking of the nature of the black powder explosion is actually quite unstable, take the ceramic grenade as an example, if the blasted fragments are collected, you can find that it is actually very uneven, its explosive force is not enough to turn all the ceramics into fragments, but there will be a lot of large fragments.

Ceramics are still like this, let alone iron sheets. Because of this, Li Tai designed the shell of the grenade to look like this, don't look strange, but such a grenade is easy to explode, and it will become much more fragments than the normal rounded version.

Li Shimin snatched the grenade and took it in his hand to look at it carefully. He didn't see much of the big one just now, but now there's a small one....

Naturally, take it apart and take a look!

The dignified emperor, like a bear child, opened the seal of the grenade, pulled out the fuse that was thin on the outside and thick on the inside, and poured out a little black powder inside, and motioned Li Jian to light it and take a look.

It was only a small amount, but after ignition, there was still a lot of smoke and a smell of burning sulfur.

The eldest grandson Wuji covered his nose and said angrily: "Your Highness, there is sulfur in this black powder?" Isn't it too unsafe to smell so easily? ”

Li Chengqian said with a smile: "If my uncle is curious, you might as well match sulfur with various things to see if you can crack the secret recipe of gunpowder." It's not a lonely boast, even if someone doesn't think about researching and wants to crack the secret recipe of gunpowder, it is not so easy to crack. ”

Datang doesn't have anything like a spectrum analyzer, and it is difficult to distinguish the composition of the materials when making molded black powder, and the materials are thoroughly mixed together.

Ridiculously enough, people have not yet discovered the properties of saltpeter ice, and even if it is useful, it is used in medicine. After studying for a long time, Sun Simiao found that the "Puxiao" recorded in the "Shennong's Materia Medica" written in the Eastern Han Dynasty and "can turn seventy-two kinds of stones" is probably saltpeter.

In the final analysis, the real charm of gunpowder is still saltpeter, but saltpeter is colorless, although it tastes bitter, but there are many bitter things, who will directly associate it with saltpeter?

In line with the idea of frugality, Li Shimin handed over the disassembled grenade to the soldiers who were driving the car, and picked up a grenade again.

"Just like before, just light this fuse, but throw this iron shell out, right?"

Seeing that the emperor was going to experiment in person, Li Chengqian hurriedly dissuaded: "Father, it's too dangerous, although it is a delayed fuse, but everyone is afraid of that in case, according to the opinion of the sons, it is better to hand it over to the warriors to experiment." For example, Lu Guogong, didn't he rush to try it just now? ”

Cheng Yanjin didn't feel like he was being cheated, but laughed and said: "Haha, I'm not afraid of old Cheng, Your Majesty, just give Weichen a little!" ”

Seeing that Cheng was about to grab the gold, Wei Chigong hurriedly said: "Your Majesty, Your Highness said to hand it over to the warriors for experiments, and Weichen feels that he is a warrior, so let's hand it over to Weichen!" ”

Cheng Biting Jin and Wei Chi Gong both robbed it, how could the eldest grandson Wuji show weakness, and he still invited Dafa as soon as he exited: "What the old man just said, but it's true, let's let the old man come." ”

Seeing that the scene was about to get out of control, Li Chengqian hurriedly said: "Everyone, there are enough grenades, everyone can get one, so don't compete for the merits." ”

Although that being said, it was the eldest grandson Wuji who won the first place.

After picking up a grenade and crooking it for a long time, the eldest grandson Wuji walked to the protective side prepared in advance and listened to Li Chengqian's explanation of the method of throwing bombs.

Outside the iron fence, there is now a big pit, and the location of the bomb is also encircled by the iron sheet, even if there is an accident, well, at most one unlucky person, unless one guy wants the whole family to die and throws the grenade into the crowd. Because of this, Li Chengqian also arranged Li Jian and Zhang Yun next to the bomb dropping position, and both of them were unsheathed, just to guard against the appearance of madmen.

The eldest grandson Wuji was not dissatisfied with this arrangement, and when he saw the two rows of dead pigs hanging in front of him, he turned around and asked suspiciously: "Your Highness, what is the matter with these two rows of dead pigs?" ”

Li Chengqian explained: "Naturally, it is used to test the power of grenades, don't you see how many pigs are wearing leather armor and iron armor?" ”

The eldest grandson Wuji nodded, and hesitated for a long time before lighting the grenade.

In the end, he was mixed up in the military, and with all his might, Changsun Wuji threw more than 30 meters, directly exceeding the passing line of bomb throwing.

There is no need to be on guard against the grenade, so the Tang monarchs and ministers have seen the whole process of the grenade explosion clearly.

Ready, the soldiers went down and carried up a dead pig. The pig had no protection, and the broken shrapnel had made a hole in its stomach, and its intestines had been squeezed out. That is, the pig's blood is empty, otherwise the scene must be very bloody, but that's it, there are still a few psychologically fragile old masters who spit it out.

The eldest grandson Wuji naturally didn't feel disgusted, and it was said that the people he hacked to death with his own hands back then were not one or two, just dead pigs, which was nothing.

Therefore, he simply asked Zhang Yun for a dagger, cut open the flesh of the pig's neck, and finally took out a piece of broken shrapnel from it.

"If you don't wear armor, you will definitely die!"

The judgment of the eldest grandson Wuji has attracted countless voices of support.

Cheng Yanjin had already snatched a grenade, and couldn't wait, so he threw out a second grenade before the soldier could send the poor pig back.

In the end, it is a military general, although the rich life in the past few years has made the weight rise I don't know how much, but the strength is still there.

With this throw, he threw more than 70 meters and directly became a "bomb throwing elite".

The scene of the grenade explosion can no longer satisfy the curiosity of the monarch and minister, and everyone is more concerned about how powerful it is.

The two rows of dead pigs arranged by the prince are well arranged, so that you can intuitively see the power of gunpowder weapons.

The second one that was brought up for the Tang Dynasty monarchs to see was a dead pig wearing leather armor.

The leather armor belonging to the grassland people, but it could not give much protection to this unlucky pig, and it was still seriously injured by fragments.

"The protection of leather armor is at most a little bit of the possibility of survival, and there is not much difference between wearing it and not wearing it."

Cheng Yanjin learned from the eldest grandson Wuji and made a judgment directly.
