Cheng Biting Jin didn't enjoy it, he still wanted to put it, and snatched one from Wei Hao's hand, Wei Hao was in a hurry, there were two left, and Cheng Biting Jin also snatched one.

"The old man will go back after letting this go, and you can leave one for Your Majesty." Cheng Yanjin watched Wei Hao keep staring at the bamboo tube in his hand, and immediately reported.

"Su Guogong, Su Guogong!" At this time, the previous Janissary Captain came over, almost running over to shout Cheng Biting Jin, and when Cheng Biting Jin heard it, he turned his head to look at the Captain.

"Su Guogong, Your Majesty summoned you to hurry up and make a report to Your Majesty about the gunpowder, in addition, Hou Ye Wei, Your Majesty said, don't do this, concentrate on assisting the Ministry of Industry to get out the fine salt, and Your Majesty will summon you in a few days." The lieutenant came over and said to Wei Hao and Cheng Yanjin.

"Oh, yes!" When Wei Hao heard this, he nodded, and arched his hand and said.

"Well, I'll finish this." Cheng Yanjin nodded, and wanted to finish the bamboo tube in his hand.

"No, Your Majesty is already angry, I don't know what the hell is going on, Your Majesty, you let me take it back." Du Wei hurriedly persuaded and said, Li Shimin was a little unhappy just now.

"Oh, give it to me!" Cheng Yanjin said and stretched out his hand to Wei Hao.

"What? Do you want this too? Wei Hao looked at Cheng Yanjin in surprise.

"Didn't you hear him say, 'Your Majesty wants?' I'll take this one back, how can Your Majesty understand it, anyway, you will do it, when the time comes, you can just make some, give me these two, I'll take them back and put them on Your Majesty. Cheng Yanjin said to Wei Hao, when Wei Hao heard it, he looked at Cheng Yanjin with a little suspicion, he was afraid that Cheng Yanjin would be released on the road.

"What kind of eyes do you have, the old man gave it to His Majesty." Cheng Yanjin stared at Wei Hao and shouted.

"Okay, you want to give it to Your Majesty, but you can't play with Your Majesty, in case something happens, but you have a relationship with us, you testify to me, if you want to let it go, you can let it go, let Your Majesty stay away, do you hear?" Wei Hao looked at the people around him, and then said emphatically to Cheng Yanjin.

"Oh, you know, I can still put Your Majesty in danger?" Cheng Yanjin snatched it as he spoke, and then said to Wei Hao: "Get fine salt, Your Majesty attaches great importance to it, you kid don't live up to this trust." ”

"Cut! Valuing yourself? If you pay attention to yourself, you should have seen yourself a long time ago, not now, when you were made an earl, you didn't see Your Majesty, and now you are a marquis, and you haven't been summoned to thank you immediately. Wei Hao thought in his heart, but he didn't dare to say it in front of Cheng Yanjin, after all, this was a bit disrespectful.

"I'm leaving, you're a good kid, remember, send some to my house, I'm okay to play!" Cheng Yanjin took the bamboo tube and left, leaving Wei Hao standing there helplessly, he originally wanted to show it to Li Shimin in person, but now that he was robbed by Cheng Yanjin, he had no way to release it himself.

"That, Master Wei, let's go get fine salt? It's been a long time coming. Duan Lun, the secretary of the Ministry of Industry, stood behind Wei Hao and said to Wei Hao.

"Cheng, let's go!" When Wei Hao heard this, he nodded, this is what I want to do today, the gunpowder just now, it was an accident. "Master Wei, can you tell me to make gunpowder?" Wang Jun still chased after Wei Hao and watched.

"Hey, I can't tell you now, but the court will definitely pay attention to the use of gunpowder, and you will know when the time comes, why are you in a hurry?" Wei Hao looked at Wang Jun helplessly and said,

Wang Jun thought about it, the entire Datang Ministry of Industry also studied gunpowder by itself, and now that the gunpowder has been made out by Wei Hao, the Ministry of Industry will definitely need to produce it in the future, and it will definitely be responsible for it when the time comes.

Soon, Wei Hao and they went to the room where fine salt was produced again, and the Ministry of Industry also selected some craftsmen to come over, they were all making salt before, and now they were transferred to learn this, after Wei Hao arrived in that room, he began to tell them the production process of this fine salt in detail, and at this moment, on the side of the Ganlu Palace, Li Shimin took the two bamboo tubes and opened them to look at it.

"That's it, making such a big move? Unlikely, right? Li Shimin took it in his hand, looked at Cheng Yanjin and asked.

"Your Majesty, let's go, let's go outside, I'll show you, I guarantee that you see it, you will definitely like it, this is a huge help for our military aspects, whether it is attacking or defending the city, it is a huge help." Cheng Yanjin immediately said to Li Shimin, he knew, let him explain, he couldn't explain clearly, but as long as he put two, they would definitely know.

"Well, it's okay, if you don't figure out what is going on, you don't know how to explain to the people of Chang'an City, let's go, go to the open space outside and have a look!" When Li Shimin heard this, he nodded, and then took the bamboo tube and came down from it.

Cheng Yanjin hurriedly followed, stretched out his hand to Li Shimin and said, "Your Majesty, you have to give me this, Wei Hanzi has explained, this is dangerous, I can't hold it for you." ”

"Well, what's the danger about this?" Li Shimin looked at Cheng Biting Jin a little incomprehensibly, but still gave Cheng Biting Gold.

"I don't know, but don't underestimate this bamboo tube, once it explodes, the power is not small, now hold it in your hand, as long as you don't ignite it, it's fine." Cheng Yanjin shook his head and said, taking the bamboo tube.

"Biting gold, you're exaggerating, it's just a bamboo tube." Hou Junji, the secretary of the military department, looked at Cheng Yanjin and said.

"If you have the ability, you just take it in your hand and let the old man light it with a fire fold?" Cheng Yanjin looked at Hou Junji with smug eyes.

"This, what are you afraid of, come, give it to me!" Hou Junji was bitten by Cheng Jin, such a general, can he be instigated? Immediately reached out.

"Come on, I'm afraid that I'll kill you, Your Majesty will kill me, and I'll let you see the effect of the explosion, and then you can tell me if you want to take it in your hand." Cheng Yanjin didn't dare to give it, but he knew the power.

"Hmph, scare the old man, the old man is scared?" Hou Junji saw Cheng biting Jin's intimidation, and immediately said proudly, soon, Li Shimin and his party arrived in a garden on the side of the Ganlu Palace, this side of the open space is large, and the square in front of the Ganlu Hall is paved with stone bricks, and it is a pity that it is blown up.

"Go ahead and give it a try, I want to see how useful this is for the military. However, there is a purpose that I have thought of, when the cavalry charges, if you throw this into the opponent's cavalry troops, it is estimated that the opponent's formation will be chaotic immediately. As long as our side is not chaotic, then the enemy's cavalry will definitely be defeated. Li Shimin stood there and said to Cheng Yanjin,

Cheng Yanjin thought about it for a while, and then said: "The minister estimates that this use is not only this, Wei Hao knows how to use it, he said that if the bamboo tube is replaced with iron, and at the same time it is stuffed with broken iron, then the power is even greater, however, the minister does not know, or need to wait for him to come to see you to know." ”

"Well, you go get it!" Li Shimin nodded, the use of this gunpowder really needs to ask Wei Hao, but whether it is useful or not depends on the situation of Cheng Biting Jinfang.

"Okay, the minister likes to play this!" As soon as Cheng Yanjin heard this, he immediately took the bamboo tube and ran forward, and Li Shimin saw Cheng Yanjin walking forward, and they also began to follow.

"Eh, stop, you just stand there, this one is dangerous, and the stone will pop out later, and it won't be good if it hits you." As soon as Cheng Yanjin saw them coming, he immediately called out to them.

"I said bite gold, what are you going to do with me as a three-year-old?" Wei Chi Jingde was not happy, the two of them were good brothers, and they used to mess around together.

"You stop, you all stop, you guys, I won't let go, stop, yes, don't come to the front, this power is really great!" Cheng Yanjin shouted at them, and now he was scared.

"What are you doing? A bamboo tube also makes you troublesome. Hou Junji also looked at Cheng Yanjin with disdain and said.

"If you have the ability, wait for me to release this, and you can hold the other one with your hands!" Cheng Biting Jin said Hou Junji, and then ran to the front, Cheng Biting Jin felt almost, immediately squatted down, found some stones, plugged the bamboo tube, and felt almost,

Cheng Yanjin turned his head to look behind him, and made sure that they didn't follow, so he immediately took out the fire fold, and after playing it, he lit the fuse, threw it on the ground, turned around and ran, ran for almost twenty meters, and immediately lay down.

"Haha!"

"Boom!" Those people saw Cheng Biting Jin lying down, and they were just about to laugh, when they immediately banged, and their ears hurt. At the same time, they also saw a scene that they had never seen before, because they saw a large number of stones and earth flying out, like a goddess scattering flowers.

"This?" Li Jing's eyes widened at this moment, and he couldn't believe the scene in front of him, because they were standing here, and they could see a huge pit on the ground.

"Hey, hey!" Cheng Yanjin got up at this moment, patted the dirt on his body, and walked towards Li Shimin and them.

"That bamboo tube was blown up just now?" Li Shimin pointed to the hole in the distance and asked Cheng Yanjin.

"Well, if you put a stone on it, it can be blown up even bigger, and the minister will go and give it to Your Majesty now?" Cheng Yanjin took the bamboo tube and asked Li Shimin.

"Shall I take a look?" Li Shimin pointed to the hole in front of him and asked Cheng Yanjin.

"Okay, it'll be fine when it's blown up." Cheng Yanjin nodded, and when Li Shimin heard this, he walked quickly to the place where the explosion had just occurred, and those ministers also followed, and they also wanted to know how powerful the bamboo tube was just now.

When they arrived, they were still shocked, although the hole was not very big, but it looked like it was blown out of a bamboo tube.

"Your Majesty, gunpowder is of great use!" Li Jing touched his beard at the moment, looked at Li Shimin and said.
