Zhao Kuangyi didn't listen anymore, grabbed a forbidden war horse, and said to them: "Go to the palace to report to Your Majesty." ”

The horse rushed towards the Donghua Gate.

Along the way, I saw many people still standing on the street, at a loss, some people were in a panic, and even the stalls were knocked over, this Zhao Kuangyi didn't care, it was a million catties of iron, with it, the country's national strength will be strengthened a lot.

Riding fast speed, a while to the East Water Gate, there are many forbidden soldiers standing by the East Water Gate, across the Dragon River, I don't know if the road is good in the past, or not in the past. Zhao Kuangyi shouted: "Don't panic, it's a mineral development developed by the imperial court." ”

What is the relationship with the imperial court? It can also be said that Song Jiu is an eight-grade literary official of the imperial court.

The horse galloped across the broken stone bridge, and when he arrived at Hezhou, he saw where many people were standing, there were more than 100 students, and more than 50 Yanei, the Han family, the Murong family, the Fu family, the Song family, the Guo family, the Yang family, the Xiang family, the Wang family, the Zhang family, the Wu family, the Chu family, the Cao family, the Pan family, Zhao Kuangyi all knew each other, it seems that Song Jiu is doing a good job, this team is gradually expanding, but the current situation is not very good. These Yanai and the students stood like wooden chickens, their heads and faces covered with mud, and they all seemed to be stupid. Song Jiu said anything, but it was as if he hadn't heard or seen it.

Seeing Zhao Kuangyi coming, he finally came to his senses.

Xiao Cao Jue and Pan Wei were grinning and crying.

Fu Zhaoshou walked over and pulled Zhao Kuangyi's arm: "Brother-in-law, it's amazing, it's amazing, it's amazing." ”

The child was probably not awake either.

Zhao Kuangyi shook his hand, waved his hand away, walked up to Song Jiu and said, "What are you doing?" ”

"The things that went into mining have been studied."

"Your movement is not small, the whole capital thinks it is an earthquake."

"That's just a firecracker, what are you afraid of."

"What firecrackers, nonsense."

"Second king, look."

Zhao Kuangyi looked in the direction of his finger, there was a big pit in front of him, because the soil of the river island was wet, it began to drip water, but it was not much, and he could see that the pit was two or three zhang deep, and it was several zhang in circumference. Zhao Kuangyi didn't quite understand, Song Jiuyi waved his hand, and several students ran to the fully organized house in the distance, and soon carried out a large wooden box. It's a little heavy, and the bar is bent.

Seeing this big wooden box, a few young second ancestors slipped away and hid behind their respective brothers, as if they saw a powerful ghost coming.

Song Jiu waved his hand, and more than a hundred students began to dig the pit.

Dr. Zhang said, "Song Jiu, you are still here." ”

"It will be applied on a large scale in the future, but the technology is still immature, not only to come, but also to keep testing."

"What is it?"

"I haven't thought of a name, the second king can call it black powder."

"It's the earthquake it causes."

"How could it cause an earthquake, it's just a little louder and a little louder to give the big guy an illusion."

There is a large amount of people, and soon a pit is dug again, several students put the box down, there is still a piece of bamboo pipe left outside the box, there is a long fuse outside the bamboo pipe, if you don't say that the firecracker Zhao Kuangyi really didn't think of it, said, it looks very similar, but it is thicker and darker. After one operation, without Song Jiu's instructions, many students began to cover the box again with mud. Then some new dirt was pressed on top of it, like a giant tomb. A student trembled and brought the fuse in front of everyone, Song Jiu lit it and said to Zhao Kuangyi: "The second king lie down." ”

"I'm wearing an official uniform."

It is not good to wear official uniforms, Fu Zhaoshou and Song Jiu pressed Zhao Kuangyi to the ground, and Song Jiu said: "Second king, plug your ears." ”

Zhao Kuangyi didn't know what happened in Lu Dao, he might have seen that the other people were lying on the ground together and didn't move, and covered their ears tightly with their hands, and thinking of the loud noise, Zhao Kuangyi also covered his ears with his hands. The fuse quickly burned to the exposed mouth of the bamboo pipe, and quickly flashed into the pipe and disappeared. Zhao Kuangyi saw that half of the people closed their eyes and didn't even dare to look. Just as I was curious, a loud noise came out, and it was not possible to cover my ears with my fingers, and my ears were buzzing, and I could barely hear the sound outside. As large clouds of dirt and turf rose into the air, it almost seemed as if the sky was obscured. In fact, it is very far away, but the surrounding terrain is restricted, the river island is mostly low-lying, Song Jiu used the high slope to build a house, it is impossible to test where the house is, so when he came here, the terrain was low-lying, it was relatively humid, maybe Song Jiu was intentional, maybe it was unintentional, in short, he chose this place.

It began to rain with mud.

Fortunately, far away, the strength gradually weakened, although it hurt but not bad, but it was powerful, the mud rain covered a large area, and the mud kept falling little by little, and it also fell on everyone, Zhao Kuangyi roared: "My official uniform." ”

No one could hear him, he himself couldn't hear what he was shouting, and his ears hadn't come back to breath.

Another huge pit appeared.

This kind of power also scared Zhao Kuangyi, and it took a long time to get up with everyone, and he was also at a loss. After a while, Zhao Kuangyi suddenly laughed wildly.

"Brother-in-law, you're fine, right?" Fu Zhaoshou asked worriedly.

"It's nothing, it's nothing, it's a good thing, it's a good thing," Zhao Kuangyi said. This little Song Jiu only saw the opening of mines, if the power is like this, not only mining mines, splitting mountains and digging roads, many mountain roads can be repaired. It can even be used for river workers to deal with those stubborn rocks. Stone is mined, and it can also be used for the military. But Song Jiu is not very clear about this, if you use a gunpowder bag, the distance of the trebuchet is close now, and it may not work. Besides, if a basin of water is poured on it and the fuse is extinguished, the powder bag loses its effect. After all, it is not a detonator. Or to make artillery, the difficulty of that technique is more complicated, and many of the principles are not known by themselves, that is, they know the way, and the casting process of this era is also doubtful. It is okay to blow up the city wall, Hong Xiuquan used the coffin to fill the black powder to knock down the Nanjing city wall and attack the city of Nanjing. However, that power requires higher quality black powder, and it also requires technical skills, and the air pressure generated by the explosion must be directly charged against the city wall to have an effect, and it is estimated that it is difficult to master at the level of Song Dynasty soldiers. In fact, in Song Jiu's heart, the biggest enemy of the Song Dynasty was still the Khitan, and the remaining Central Plains countries could easily take it without gunpowder. However, the Khitan are nomadic people, and in addition to dealing with the city walls of Youzhou, this trick in the wild does not work. How to use it in the military, Song Jiu will not care, let the craftsmen of the imperial court figure out a way.

With some congenital conditions, gunpowder appeared in the late Tang Dynasty and was also used in the military, rockets, which were incendiary, not explosives. Gradually, people used it to make firecrackers. The Song Dynasty also had gunpowder, the three materials were not pure, the proportions were not right, and I don't know how powerful it was, so now there is only one gunpowder weapon, or a rocket!

Song Jiu began to purify the nitrate and sulfur, and could only use the original method of soil to purify, and it took more than ten days before and after, and then granulated it while debugging. The amount used during debugging was very small, and it was also rolled into a firecracker form for testing, so the officials thought that Song Jiutian was setting off firecrackers. It took several days to determine the original granular black powder, which was still not of high purity, but the proportions were certainly correct. Zhao Pu didn't let go of the eagle if he didn't see the rabbit, Zhao Kuangyi explained, he still didn't let go of the eagle if he didn't see the rabbit, Song Jiu held his breath in his heart, and didn't shout a single one, but invited this group of Yanei to Hezhou together in the name of hunting. Not only hunting together, but also inviting you to eat bread at night, hunting is a pleasure, and eating bread is more desirable, and as a result, more people come to the yanai.

Then he said that I will make a good thing for you to see, and I have instructed it, but a group of Yanai hip-hop and hip-hop did not take it seriously, their ears were not covered properly, and some of them were still standing, and they were not mentally prepared, so they blew up, and they were stunned together.

Song Jiu rubbed his ears and said, "Second king, where is the grave." ”

Ten pictures have been drawn, but the grave has not been moved, but I dare not paste it, so I can only reopen the first painting and replace the old painting. Can't be posted, once it's posted, pay attention to Hezhou, there will be a lot of greedy people, the ownerless grave is not the same thing, and the problem of the commoner's grave is not big, but there are some powerful graves, and there is an opportunity point with the grave, and the trouble will get bigger and bigger in the future. As long as ten paintings are posted, Zhao Kuangyin can't move the capital if he wants to.

"You kid, every time the court takes your things, it's hot," Zhao Kuangyi finally stopped laughing, and he also rubbed his head. Before he came out and thought of it, as soon as he thought of moving the grave, he also had a headache. Ignoring it for the time being, he said, "Song Jiu, you take me to your house to have a look." ”

"The two kings, there are many people and miscellaneous hands, this technique is to be paid attention to by the imperial court......"

"Yes."

Song Jiu said to everyone again: "Everyone, let's go back, I will make bread for you to eat." ”

Everyone was frightened, and they had to comfort their wounded hearts.

"Let's go, eat bread," Zhao Kuangyi said. This kid only made bread once, and it spread evilly, saying that it was a heavenly delicacy, and he was embarrassed to force him to make it, and today he can finally taste it. The group walked back with a smile, and the natural psychological reaction after the fright, only Zhao Kuangyi smiled the most heartily and happily.

The second explosion alarmed more people, and in fact the city began to panic at this time, and I don't know how many small stalls in the road were knocked over by people who fled from their homes. The guards and forbidden soldiers of the East Water Gate also walked across the Molong River, and Zhao Kuangyi waved his hand and said to them: "You quickly pass on my order, saying that the imperial court is developing and opening minerals, and it has been successful, if it is not an earthquake, don't let the people in the city panic." ”

That's reassuring.

"Whoa." The soldiers replied, but they looked at the embarrassment of the group, and covered their mouths with joy as they went back to give the order. Under the watchful eyes of all people, more than 100 people entered the river, and the streets were still full of people, and they all felt strange when they saw this group of people coming. Someone had sharp eyes and whispered: "Isn't that the second king and Xiao Jiu?" ”

"Two kings? Could it be that the two kings led them to roll in the mud pond? ”

"You kid, you have lost your good image as an official," Zhao Kuangyi said depressedly.

"Second king, think about those gold, silver, copper, iron, tin, lead, you can secretly have fun."

There are still people in the academy, Yuping and Cui'er, Zhao Kuangyi also knows about the news that Song Jiu doesn't know about the Dao, this Yuping is dead and is talking to Song Jiu, so he almost doesn't entertain guests during this time, and the small brothel is about to close. It had nothing to do with him, the first one rushed to the well, and he couldn't see himself, but the others became a clay figure, and he couldn't get any better. Jade Ping also stood in the doorway, looking at the group of happy people in disbelief, "What are you guys?" ”
