Wei Hao looked at the stunned officials of the Ministry of Industry, smiled proudly, and then prepared to walk towards the place of the explosion with his hands behind his back.

"Hou Ye Wei, this, this, just now the bamboo tube was fried?" Duan Lun only came back to his senses at this moment, and when he saw Wei Hao walking over there, he immediately asked.

"That's right, if I hadn't gone ahead just now, the explosion would probably have injured you!" Wei Hao stopped, turned his head to look at him and nodded and said.

"Hou Ye Wei, Hou Ye Wei, how did this come out, does gunpowder have such great power?" Wang Jun also hurried to Wei Hao's side at this moment, and said to Wei Hao feverishly.

"Of course, you're playing pediatrics. Okay, I'll see how the frying goes. Wei Hao smiled and walked to the front, and Wang Jun hurriedly followed, wanting to see it too.

"This, Shangshu, this matter, it seems to be of great use, you see over there, there is a big pit, and you look at that wall, many places have been splashed with splashes, if it is blown up on people?" A craftsman stood behind Duan Lun and whispered,

Duan Lun was frowning at the moment, feeling that this was not a good thing.

And in the palace, Li Shimin and the others were also outside at the moment, wanting to know what the explosion was.

"Do you know where the noise came from?" Li Shimin asked the Praetorian Guard soldiers at the door.

"Back to Your Majesty, it was too sudden just now, and it looks like it came from the direction of the Ministry of Industry. But I'm not sure, it's too loud. The Praetorian Guard soldier hurriedly said to Li Shimin.

"I guess it's the Ministry of Industry that has made something out of it, and something has exploded, hey!" Fang Xuanling in the back sighed and said.

"Well, send someone to take a look and see if something is wrong, but it looks like there is no smoke, so it is estimated that there is no major incident!" Li Shimin nodded, thinking that there might be an accident in the Ministry of Industry, and such accidents have not happened before, but they are not so frequent, and the previous sound was not so loud.

"Yes!" A lieutenant immediately gave up his hands and went out, and Li Shimin took those ministers back to the study of Ganlu Palace.

And when Wei Hao arrived at the place of the explosion, he saw a big pit on the ground, which was also a little surprising, although this is a bamboo tube, but because it contains a little too much gunpowder, it is very powerful, and it can be put on the open ground, and it can blow up such a big pit.

"Well, yes, try how it works if you put it on the ground." As he spoke, Wei Hao took out a bamboo tube again, began to plug it, and then buried it in the big pit just now, on which Wei Hao pressed a stone.

"Hou Ye Wei, do you want to blow it up?" Wang Jun saw that Wei Hao was about to ignite, and immediately looked at Wei Hao and asked.

"Try it, the cannon battle just now was still very loud, now look at the power buried in the ground." Wei Hao turned his head and said to Wang Jun with a smile.

"Yes, it's just, it's a bit loud!" Wang Jun reminded Wei Hao and said.

"It's okay, remember to block your ears, if it's blown up, don't blame me, you run first!" Wei Hao said to Wang Jun,

When Wang Jun heard this, he didn't dare to slack off, stood up and ran back: "Everyone, plug your ears, it's going to explode again." ”

"Ah, this!" Duan Lun was a little surprised, more helpless, and then found that all the people around him turned around and ran back, Duan Lun turned his head and looked, and immediately thought of it, it had just exploded, but someone was hit in the head by a stone, although it was fine, but it also hurt, didn't it? So I hurriedly ran to the back as well.

And Wei Hao saw that Wang Jun was in the back, and immediately took out the fire fold, lit the fuse, turned around and ran, feeling that he had run thirty or forty meters, and immediately lay down, and those officials were still in front of Wei Hao, and they were at least fifty meters away from the place where the explosion occurred.

"Boom!" Then the people of the Ministry of Industry saw a stone flying, at least twenty meters away, and then slammed into the ground, and those officials of the Ministry of Industry looked at this scene in surprise at the moment, thinking, if this stone fell on their heads, then there was still a chance to live.

"Yo, it's not small!" Wei Hao got up from the ground at this moment, a little surprised, but more proud,

In the palace, Li Shimin had just sat down, and suddenly there was a bang, and he was so frightened that he almost didn't dig the brush.

"What the hell is going on, such a big movement?" Li Shimin was talking annoyed at the moment, it was simply not like words, he was scared to death, the key was that they didn't know why it exploded.

"What's wrong?" Those ministers were also thinking about this in their hearts, and there were two explosions for no reason, and the movement was so loud that it was estimated that the entire Chang'an City heard the explosion.

"Your Majesty, this matter still needs to be investigated, otherwise, it will cause panic in Chang'an City." Fang Xuanling stood up and said worriedly, thinking in his heart that if the guidance was not good, there would be no rumors coming out, and then it would be troublesome.

Li Shimin stood up again and took those ministers to the outside of the Ganlu Palace, wanting to see what the situation was, after all, the Ganlu Hall was very high and could see most of the area of the palace.

"Look at the Ministry of Works, is there a little smoke coming out?" Li Shimin's eyes were sharp, and he saw a cloud of white smoke floating on the Ministry of Industry.

"It seems to be!" The ministers heard and nodded.

"Did you hear that voice just now?" Li Shimin then turned to look at the Praetorian Guard soldier behind him.

"Back to Your Majesty, I heard clearly, it was indeed a movement from the Ministry of Industry." The Praetorian Guard soldier immediately nodded in the affirmative.

"Biting Jin, you take a team of Praetorian Guard soldiers to see what happened, and in addition, I will let Duan Aiqing come to the Ganlu Palace, and I will ask him to pass by." Li Shimin said to Cheng Yanjin with a dark face.

"Yes!" Cheng Yanjin immediately surrendered his hand, then took his weapon from the Praetorian Guards of the Ganlu Palace, and went down the stairs of the Ganlu Palace, ready to go to the Ministry of Industry to have a look.

"Well, look at this big hole, it's two feet deep, this is still on it, covered something, if you dig a small hole and put it in, then the effect will be better." Wei Hao still said to Wang Jun very proudly.

"Yes, yes, it's just how to make this, please let Hou Ye Wei tell me one or two." Wang Jun stood behind Wei Hao and said to Wei Hao piously, he also knew in his heart that the one in front of him really knew how to make gunpowder, but why it was so powerful, he didn't know, he really wanted to see what was in the bamboo tube, and wanted to pour it out and study it.

"That's not possible, I can't tell you, if it leaks out, it's going to be troublesome." Wei Hao said and grabbed the remaining bamboo tubes.

"This, Marquis Wei, I am also an official of the court, and I am also an official of the Ministry of Industry." Wang Jun looked at Wei Hao in a little surprise and said, how about being a Tang official, so he doesn't trust himself so much?

"I know, but it still doesn't work, why don't we play a few more? Anyway, there is! It's not convenient for me to take so much back. Wei Hao looked at Wang Jun and said.

"Don't you? The movement is too big, this is the palace, and it will not be good if it scares people out of something. Wang Jun reminded Wei Hao again and said, when Wei Hao heard it, it was right, it would not be good if he scared people.

"Hou Ye Wei, Hou Ye Wei, don't order!" At this moment, Duan Lun also trotted over from behind, he was really frightened just now, and he also knew the power of this thing, and even thought of how to use this thing, if it was handed over to the army, it would definitely be of great use.

"No, you go find me a cloth bag, I'm going back with these things." Wei Hao said with a smile at Duan Lun.

"This, you have to take it back, I'm afraid it won't work, right?" Duan Lun hesitated for a moment, looked at Wei Hao and said.

"Why not?" Wei Hao was stunned for a moment, looked at him and asked.

"After all, this is something from our Ministry of Industry, of course, it is indeed something you researched, but this thing of yours is of great use to our court, and it is better for you to contribute to the court." Duan Lun reminded Wei Hao and said!

"I know, I will give it to Your Majesty, and I will enter the palace to thank you after a while, and I will hand it over to Your Majesty with my own hands." Wei Hao nodded and said to Duan Lun very seriously.

"No, Marquis Wei, you can't hand over this thing to Your Majesty, after all, this is very dangerous, if something happens, then, then..." Duan Lun pointed to the bamboo tubes in Wei Hao's hand and said to Wei Hao.

"Ah, oh, got it!" Wei Hao thought of this and nodded.

"So, please leave it to the old man, the old man will show His Majesty how to use it, and this is of great use to my Tang army." Duan Lun continued to speak to Wei Hao.

"Yes, Duan Shangshu, it's a bit of an eye!" When Wei Hao heard this, he nodded appreciatively.

"Master Wei, this?" Duan Lun continued to point to the bamboo tube in Wei Hao's hand.

"Still no, I want to give this to Your Majesty personally, I can't borrow someone else's hand, if something goes wrong, I'll be unlucky." Wei Hao thought about it for a while, and felt that it still didn't work, this thing was indeed a bit dangerous.

"This, it's done, but you can't order it, the old man estimates, His Majesty will send someone to inquire about this matter later, you listen to the sounds of the horses outside, I guess they are all startled." Duan Lun said a little crying and laughing at the moment, the power just now was not small.

"Did that sound come from here?" At this time, a lieutenant with a few Praetorian Guard soldiers came to the backyard and shouted at the people inside, Duan Lun turned his head and found that it was the lieutenant on duty next to the emperor, so he immediately trotted over, and Wei Hao also followed.

"That, misunderstanding, just verified something new, alarmed Your Majesty, and the minister is guilty!" Duan Lun arrived at the captain's side and hurriedly said to the captain.
