Gunpowder has been available since the Spring and Autumn Period, but it has not been used militarily. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info And gunpowder has not been perfect for a long time, and gunpowder has not even been used in people's livelihood. In fact, it is very simple to mix explosives, only need to mix sulfur, saltpeter, and charcoal in a certain proportion. If you want to be more powerful, you can make the explosives into granules, so that the explosives have enough air to provide them with sufficient combustion. But now that the imperial court is going to send troops to the Turks in three days, Wang Haoran can only make some simple methods of use, that is, explosives packs, and as for the lead, he will use felt to dip some gunpowder in it first.

Due to the urgency of time, Wang Haoran had no choice but to call Chen Jun, who was resting, over to help toss for an hour or two before making an explosive bag. Wang Haoran explained to the people in the factory that there might be an explosion later, so there was no need to panic, so he came to an open place and put the explosive bag on the flat ground, telling Li Tai and them to hide away. Chen Jun did not leave, insisting that he go and light the explosives bag himself. When he was experimenting with the lead just now, he could guess a few points of the power of this large bag of explosives, and if he was not careful, he could die.

"You don't know this thing yet, so I'd better do it." Although Wang Haoran knew the power of this explosive, he didn't worry much, after all, he made the lead very long, enough for him to run to a safe place.

"Little master, let's come with me. Even if there is an accident, it is not a big deal. But young master, you still have a lot of strange things in your head, and I can't let you take this risk. ”

Wang Haoran couldn't resist Chen Jun, so he pointed to the place where Li Tai was and explained: "Then you can run over at one point, remember to cover your ears!" ”

When Wang Haoran arrived at Li Tai's side, Chen Jun carefully lit the fuse, and hurriedly ran away at one point. Because the lead is very long, when Chen Jun came to Wang Haoran, he didn't explode after waiting for a while.

There was a sudden loud bang, like a landslide and the earth cracked, and the earth trembled.

Although Li Tai and Chen Jun were prepared, they were still so frightened that their faces turned pale. Wang Haoran ran over with a smile to see how powerful it was, but he was a little disappointed when he saw that the ground had been blasted out of a pit one or two meters wide, but there was absolutely no problem with such power being used to blow up the city gate.

Li Tai also ran over to see, his heart was still jumping. When he saw this pit, his expression was solemn, and he said, "I'll go see my father now." ”

"Well, Chen Jun and I made some here overnight, and we will also study if there are other uses that can be used on the battlefield."

"Hmm." Li Tai didn't talk nonsense, got into the carriage and hurried to the palace.

Li Tai returned to the palace, it was already dark, and the guards in the palace had increased a lot more than usual at this time, could it be that something happened in the palace? Li Tai hurriedly quickened his pace.

When Li Shimin was found, his mother's eldest grandson, Empress and the crown prince Li Chengqian were also there, and before Li Tai could speak, Li Shimin strode over and said with concern: "Tai'er, you are back!" Why did you come back so late? ”

"Father, what's going on in the palace? Why are there so many guards patrolling? Li Tai asked.

"Nothing happened, but there was a noise from outside the city just now, and they were on guard."

"Oh, I see." Li Tai put his mind at ease and said with a smile, "Father, queen mother, don't worry, the child is here for this matter." The movement just now was made by the child who watched Wang Haoran make it with his own eyes. ”

"Oh? It's Wang Haoran's kid again! How did he make such a big move? Li Shimin asked curiously.

Haoran said that he found something in a research some time ago, called explosives, which are powerful, and if they are used, they will definitely be able to help their father on the battlefield. Today, Haoran heard that his father wanted to send troops to the Turks, so he mentioned it to the child, but the child didn't believe it, so he asked him to experiment with the child first, which was the loud noise just now. ”

"Can this thing really help me attack the Turks?" Li Shimin was surprised, compared to this, the strange thing of a ten-year-old child doing research was directly ignored.

"Yes, indeed." Li Tai gestured at the size of the explosives bag and continued, "A bag of explosives of this size can blow up a large pit six or seven feet on the ground, and Haoran said that it is easy to blast open the city gate with this. ”

"Is it really that amazing? Does he still have it? Li Shimin's eyes lit up with excitement, if it really had this effect, it would really help him a lot. In ancient battlefields, the most difficult war to fight was to storm the city, and I didn't know how many people had to be sacrificed just to break through the city gate.

"Yes, he is still making it, and I want the child to ask his father first, and he will bring it to his father tomorrow."

"No, I'll go and see it now. Fu'an, quickly passed the eldest grandson Wuji, Li Tao, Chai Shao and other generals into the palace. Li Shimin was anxious to see the power of explosives, and now it was less than three days before the army could be mobilized, and if this thing was really useful, it would take time to make it, and time was pressing. And the reason why the generals were called was because Wang Haoran was only a ten-year-old child, and the explosives were discovered not long ago. It won't take long to call these generals to think of a suitable way to use it, so that it can also be made in a short time and used on the battlefield in three days.

Wang Haoran and Chen Jun had already made an explosive bag, but it was much smaller than the first time, and it was going to be brought into the palace for experiments to show the emperor, and it would not be good to blow up the palace if it was too big. In addition to the explosives package, Wang Haoran also made several "grenades", which were just a big firecracker. They were about to go out and test their might when they saw a large crowd of people coming not far away with torches. When they got closer, they found that it was the emperor and the generals, so they hurriedly greeted them.

After Wang Haoran and Chen Jun saluted, Li Shimin asked anxiously: "I heard from King Wei that Wang Haoran made something called explosives, where are you now?" Take a look. ”

"Your Majesty, the grass people have made a small explosives bag, and I wanted to bring it into the palace tomorrow to show the emperor, but I didn't want the emperor to come over today. It's just that the emperor can't see it now, the explosive package is extremely powerful, and the desire will explode, and there are a lot of open flames, I am afraid of accidents. However, the grass people also made a smaller one, and were about to test its power, and the emperor and the generals could go with the grass people to see it, and they could also see the crater opened by the explosive pack today. ”

"In that case, then you can lead the way."

Wang Haoran took everyone to the big pit and said: "This is the pit that was blown up today, and the big reason why such a big pit can be blown up is that this land is relatively soft, but if it is used properly, that explosive bag can also blow up a pit bigger than this." ”

"So how do you use it properly?" Li Shimin asked.

"For example, dig a hole in the ground, bury the explosives in it, and then ignite it. If you want to blow up the city wall, you can dig a hole in the wall, and if you want to blow up the city gate, you can just hang the explosive bag on the door. "Wang Haoran directly said the method of using the explosives package on the battlefield, anyway, Li Shimin knew that he made this explosives package to help him fight the Turks, so don't worry that they will think of blowing up the gate of Chang'an City." If the two armies face each other, they can tie gravel to the explosive pack, and after igniting it, use a stone-throwing cart to throw the explosive bag to the enemy camp. ”

Li Shimin and the generals took a breath of cool air, shocked by the power of the explosives pack, and at the same time, they also felt that this kid was incredible, a ten-year-old child could talk eloquently about the battlefield, and when it came to killing people, his face could not change, what kind of evil is this!

"Is there any other way to use it?" Li Shimin heard Wang Haoran say all of a sudden about how to use them, and he forgot for a moment that he brought these generals here to discuss how to use them.

"If it is only used on the battlefield in three days, then there are only these methods, but the emperor can send someone to study this explosive in the future, and its use is not only that." Wang Haoran pointed to Chen Jun, who was standing a little farther away, and continued, "Your Majesty, the smaller explosive bag made by the grass people is in the hands of my friend, and the grass people call it a grenade, do you want to try to show it to the emperor and the generals now?" ”

"Well, let him try it."
