Li Jing said that this thing is very useful, of course Li Shimin also knows, after all, he is also a military general, and the explosion just now, he knew at a glance that if it was used on the battlefield. How powerful.

Li Shimin soon arrived at the place of the explosion, and looked at the hole, although it was not big, but it was a bamboo tube just now.

"A small bamboo tube has such power, I see, there is not much gunpowder in it, right?" Li Shimin looked at the hole and asked.

"It's definitely not much, it's so light, look at it, Your Majesty!" Cheng Yanjin said and handed the remaining bamboo tube to Li Shimin, Li Shimin took it in his hand and weighed it, it was indeed very light.

"Your Majesty, when the ministers cover this bamboo tube with a stone and light it, Your Majesty will be able to see how powerful this is, and it will be even more powerful than throwing it on the open ground like now!" Cheng Yanjin said to Li Shimin with a smile.

"Okay, let's get it, let's retreat back!" Li Shimin nodded, thinking about this in his heart, and the other ministers also followed him to the back, while Cheng Yanjin continued to stuff stones into the bamboo tube.

"Your Majesty, Wei Hao is a talent, and if you go to the Ministry of Industry, you can still get gunpowder out. As for the Ministry of Industry, I don't know if there has been any research on this object before. Fang Xuanling stood beside him, looked at Li Shimin and said.

"Well, I don't know about this, but it's not easy to get this thing." Li Shimin nodded, he already wanted to see Wei Hao a little in his heart, after all, Wei Hao's ability was already very useful to the court, from the paper at the beginning to the gunpowder now, it was all used to contribute to the court.

"Your Majesty, I'm ready here." Cheng Yanjin stood up, looked at Li Shimin behind him and shouted.

"Then order it." Li Shimin also shouted at Cheng Yanjin, Cheng Yanjin heard it, immediately squatted down, lit the fuse, turned around and ran, the speed was very fast, and he also ran for more than 20 meters, and Cheng Yanjin immediately lay down.

"Boom!" With a bang, Li Shimin and the others saw a big stone flying, and it flew very high, and then it fell heavily to the ground.

"Your Majesty, look!" Cheng Yanjin stood up from the ground at this moment, and looked proudly at the big hole behind him, which was still smoking.

"Is it so powerful?" Li Shimin and the others were also stunned, the explosion of a small bamboo tube could actually blow up such a big stone, Li Shimin said and walked forward,

And Wei Hao was on the side of the Ministry of Industry, and after hearing the explosion, he immediately said helplessly: "These two bamboo tubes were blown up by him like this?" That's too fast, right? ”

After Duan Lun heard this, he said to Wei Hao with a wry smile: "Master Wei, you still have to concentrate on this, and the gunpowder can't run." ”

"I can't run this either, aren't you doing it now?" Wei Hao replied with a smile and continued to guide the craftsmen in the Ministry of Industry to work.

"Your Majesty, look at it, this hole is big, if we attack the city, we stuff bamboo tubes in the cracks of the city wall, and fill it with enough gunpowder, when there is a little bang, we may be able to blow up the city wall." Cheng Biting Jin was next to him and said with a smile at Li Shimin.

"Well, gone?" Li Shimin looked at Cheng Biting Jin's empty hand and asked.

"Huh? Oh, no, just two, Wei Hao made a total of eight, he blew up three himself, I blew up three over there, and the last two are here. Cheng Yanjin said to Li Shimin with a smile.

"Well, let him do some more?" Li Shimin looked at the other ministers as he spoke.

"Your Majesty, this is not necessary, anyway, the effect can be seen, when the time comes, let Wei Hao come up with the production method, and how to apply it later, I think only Wei Hao knows, although we can guess some, but how to achieve it, may not be as good as Wei Hao!" Li Jing looked at Li Shimin at this moment and suggested.

"Yes, Your Majesty, now Wei Hao is instructing the Ministry of Industry to do fine salt and gunpowder, anyway, Wei Hao will, don't worry, now Your Majesty, you won't summon him, if you summon him, it's okay!" Fang Xuanling knew some things about Wei Hao and Li Shimin, and he also knew why he didn't summon Wei Hao.

"Well, that's okay, by the way, the people of Chang'an City, it is estimated that they are frightened enough by these explosions, the Ministry of Civil Affairs here, immediately post an announcement to appease the people, this Wei Hanzi, come to the palace, you have to make something happen." Li Shimin smiled bitterly as he spoke,

When Fang Xuanling heard this, he laughed, and the other ministers didn't know what he was laughing at, but Wei Hao, who was in the Ministry of Industry, was busy until noon before he taught those craftsmen to understand, Wei Hao watched them do it again, and only after they were all done, did they go back. And Duan Lun also arrived at the side of the Ganlu Palace, and at this moment, those ministers had already gone back.

"Fine salt ready?" Li Shimin looked at Duan Lun, who had just come in, and asked.

"Back to Your Majesty, it's all out, and our craftsmen have also mastered this skill." Duan Lun hurriedly waved his hand and said.

"Well, what the hell is going on with that gunpowder?" Li Shimin looked at Duan Lun and continued to ask.

"Back to Your Majesty, at this time, the minister also wants to report, it's like this..."Duan Lun immediately reported to Li Shimin from the fire in Wang Jun's office to the process of Wei Hao getting out the gunpowder.

"Oh, so to speak, the Ministry of Industry was also researching gunpowder before, but it didn't work out, and Wei Hao just arrived at the Ministry of Industry, so he researched it?" When Li Shimin heard this, he felt a little shocked.

"Yes, and he is very familiar with the use of gunpowder, at first Wang Jun didn't know that gunpowder could also be contained in a bamboo tube, and it could cause such a loud explosion." Duan Lun nodded and spoke.

"Then according to what you said, Wei Hao got this gunpowder before? How could he, who taught him? Li Shimin immediately stared at Duan Lun and asked, now that he thinks of Wei Hao, he has made paper, porcelain, etc., this is not something that a fool can do, he has no ability, but he can't do it.

"This, the minister doesn't know, maybe someone taught him." Duan Lun immediately spoke.

"Well, it's possible, okay, I asked you something, let Wei Hao come to the Ministry of Engineering to be on duty, okay? Of course, not yet, he hasn't been crowned yet, but this winter, he will be crowned, and when he is crowned, I can give him an official and let him come to the Ministry of Industry. Li Shimin looked at Duan Lun and asked.

"This, of course it's good, it's just that, Your Majesty, you also know that the Ministry of Industry is a rigorous place, whether it is doing things or doing research, it needs to be studied, and Master Wei, I also know that he is a straight person, if you come to the Ministry of Industry, if you suffer some grievances, it will be bad if it causes a conflict at that time." When Duan Lun heard this, he was immediately a little reluctant, he admired Wei Hao's ability, but he was still a little afraid of Wei Hao's character, Wei Hao had fought so many times outside, he knew it.

"Oh, I know, I'll talk about him, let him restrain some of his character, in this case, wouldn't it be better?" Li Shimin looked at him and continued.

"Yes, if Your Majesty lets him come, of course our Ministry of Industry will have no opinion." Duan Lun heard Li Shimin say this, so what else did he say?

"Okay, that's it for now, and I have to ask Wei Hanzi what he means." Li Shimin knew that Duan Lun was unwilling, but Li Shimin still hoped that Wei Hao could make greater contributions to the court in the Ministry of Industry.

At noon, Li Shimin arrived at the Lizheng Palace, mainly because he knew that every day Li Lizhen would bring food from Juxian Building, and Li Shimin was also picky now.

"Your Majesty, there was a huge explosion in the palace today, what the hell is going on? The people are panicked, and the puppies raised by the slaves are all scared! Empress Changsun looked at Li Shimin and asked.

"Eh, don't mention it, what Wei Hanzi made up." Li Shimin said with a wry smile.

"Ah, he, what's wrong with him?" Li Liqing, who was holding her son-in-law on the side, looked at Li Shimin in surprise.

"In the Ministry of Industry, I made a gunpowder, stuffed it into a bamboo tube, and after ignition, it will explode, and it is very powerful.

By the way, Lizhi, my father asks you, how does Wei Hao understand those things, I remember that his writing is very ugly, how can he be so familiar with these things? Li Shimin looked at Li Li and asked, for this matter, Li Shimin couldn't understand how a person who didn't learn and didn't know how to know these things.

"This daughter doesn't know, anyway, he said himself, except for studying, not giving birth, everything else is fine." Li Lizhi shook her head with a smile and said.

"This kid, the tone is very big." When Li Shimin heard it, he also smiled.

"Your Majesty, no matter how he knows, anyway, his ability can be used by the court." Empress Eldest Sun also smiled.

"That's right, Lizi, you go and ask Wei Hanzi if he is willing to serve in the Ministry of Industry, and after he is crowned, I will let him serve as the waiter of the Ministry of Industry." Li Shimin said to Li Lizhen again, Li Lizhen heard it and was stunned for a moment, and the eldest grandson queen was also a little surprised, so young, to serve as a waiter in the Ministry of Works, this starting point is too high.

"Okay, but, father, he has just entered the official career, and of course he is a squire in the Ministry of Works, I am afraid that it will cause dissatisfaction among those ministers. Isn't it a bit too high? Li Lizhi looked at Li Shimin and asked.

"The concubine also means this, I'm afraid it will be difficult to convince the public!" Empress Eldest Sun also nodded at Li Shimin and said.

"It's okay, on the side of the Ministry of Industry, I have not been able to find a suitable person, the two Ministry of Industry attendants have been vacant, Duan Lun is also old, and he feels a little like there is no successor, so it is not impossible to let Wei Hao go, and the Ministry of Industry is not something that anyone can pick up." Li Shimin shook his head and smiled and said, the Ministry of Industry is indeed in a troublesome situation, and no one is available.
