"Doctor Wei, you're fine, are you?" Liu Yuan couldn't help but smile and walked up, carefully picked up this Wei Heizi who accused him of his black appearance, and carefully helped him up.

Obviously, he was not prepared at all, he was frightened by the explosion just now, after all, it was an old man, in fact, it was not only him, but most of the officials present, including Li Er and Li Qiancheng, were also frightened and white-lipped, with their knowledge and the world's view of the world, they could not understand the huge destructive power of gunpowder, for them, this was a product of the times.

"No, no, thank you General Liu Liu." Wei Heizi hadn't reacted yet, and his speech was a little unfavorable.

This cowering look, how can it be like a famous minister who dares to risk death to admonish directly, compared with the high-spirited when he accused Liu Yuan and claimed to impeach Liu Yuan just now, one is in the sky and the other is underground, and now he is not much different from an ordinary old man.

The years are not forgiving, after all, they are the relics of the previous dynasty.

"Come on, give me a seat, let Wei Aiqing have a good rest." At this time, Li Er showed his emperor's mind again, after all, he had experienced too many winds and waves, and he was bold, so he quickly came back to his senses, and An Shi cared about the body of his courtiers.

This time, Wei Heizi did not refuse, and reluctantly saluted Li Er, and whispered, "Thank you, Emperor." After speaking, he sat down to rest with the support of the guards.

"Liu Yuan, you stinky boy, what kind of immortal art did you use just now? Say it quickly, say it quickly" Old Demon King Cheng reacted, ran over all of a sudden, grabbed Liu Yuan's hand and shouted loudly.

"Yes, Xiaoyuan, this, this is amazing, are you talking about the power of gunpowder?"

"How?"

"General Liu, how can you pour a little black soil. Burn it with fire, and it will blow the stone apart, what is that black powder? ”

"Good son-in-law, you really give the old man a long face, good, good."

"Just three thunders, the amount of stone mined, visually measured to thousands of people in a month's mining, wonderful, wonderful. No wonder he dared to say that he could flatten this stone mountain in ten years, General Liu, Xiao was willing to bow down and obey. ”

"No wonder there is a blockade, and there is a lot of fanfare in Chang'an City. It turns out that there is such a deep meaning, and just now a certain person also said that labor and money are lost. It was really wrong. ”

Everyone surrounded Liu Yuan and gossiped. There was a scorching light in his eyes, and for a while, Liu Yuan didn't know which one to answer, so he had to respond resignedly.

"Liu Qing's Family"

"Weichen is here" As soon as he heard Li Er's voice, Liu Yuan was liberated all of a sudden, and immediately pushed away the hand of the Great Demon King Cheng. ran in front of Li Er, fortunately, when he heard that it was Li Er who summoned Liu Yuan, the minister of civil and military affairs who had lost his temper had to let Liu Yuan go.

Li Er pointed to the stones on the ground. He said a little excitedly: "This, these actions just now, are they caused by the gunpowder you said in your mouth?" ”

"Back to the emperor, it was indeed gunpowder that blew the stone apart."

"Well, I read your battle report in Tubo, saying that you used gunpowder to blow up the Tubo Immortal Stone, pretending to be a god to provoke the rebellion in Tubo, to be honest, I thought you were talking nonsense, intending to cheat the war merits, but I sent someone to ask a few people who followed you, all of them were of the same caliber, so I recorded your merits in the book, and rewarded your merits, but I didn't expect to see it with my own eyes today, I knew that what I said was true, good, good, you are really my lucky general, hahaha"

After Li Er finished speaking, he laughed happily.

"Don't dare, it's all thanks to the emperor." Liu Yuanjia said modestly.

Li Jing on the side suddenly said: "If this gunpowder is applied to the siege of the city, then the hard stones can be blasted apart, not to mention the rammed earth city wall?" This can be a sharp weapon for attacking cities and grabbing land. ”

As soon as the words came out, everyone was shocked, civil officials rarely participated in the war, and they didn't have much understanding of this, but the military generals were different, and when they heard the words, their eyes were wide open, it was Li Er, and their eyes were also shining, as if they had received a great piece of good news.

When attacking the city, the city wall is the first level, and it is also the most difficult to fight, the most casualty level, that is the defender makes full use of the advantages of the city wall, condescending, taking advantage of the terrain, if, there is no city wall or the city wall falls? The hard stone mountain can be exploded, not to mention the much more fragile city wall of the stone mountain, just imagine, when the siege is, suddenly the city wall falls, in the case of surprise, not only death and injury are inevitable, the shock in the heart is indescribable, the attacking side, can easily kill people in the city, as long as it is used well, there is no city in the world that cannot be broken.

What a weapon!

It really deserves to be the god of war, and whatever it is, it is applied to the war for the first time.

"Liu Aiqing, you said, is it okay to use it to blow up the city wall?" Li Er suddenly asked nervously.

Liu Yuan nodded and said, "You can blow anything, and the city wall is naturally no exception." ”

"Liu Qingjia, where did the gunpowder you mentioned come from? This king looked at the gunpowder, it was as black as cement, it was not inconspicuous at all, I didn't expect it to be so powerful, it was really amazing. ”

"This"

Li Ertu interjected: "Okay, let's talk about this matter back to the palace, Liu Yuan." ”

This gunpowder is too important, Li Er keenly feels that because of the emergence of this gunpowder, it is possible to produce a new model in the war, unprecedented destructive power, as long as it is used properly, it can definitely greatly improve the combat effectiveness of the army. Li Er thought about the story that Liu Yuan told him, outside the Tang Dynasty, there was a broader land, a richer place, more products, a population and beautiful women, for fear that Liu Yuan would say it, and Li Er would immediately interrupt.

Maybe this thunder woke up the dream of the world in Li Er's heart

"Wechen is in"

"I see, there are hundreds of wooden barrels you brought last time, and they are full of gunpowder, right?"

Liu Yuan didn't hide it, nodded and said: "Yes, it's all gunpowder, which is used to flatten this stone mountain, your Majesty, you can also see that this stone mountain is so tall that it can be flattened without explosives a few times, these hundreds of barrels are definitely not enough, and we have to continue to make them." ”

"Okay, then let's continue to blow up, like some shocking scenes, it's rare to look back in life" Li Erbao said: "Let's take a good look today, I haven't seen enough of the power of this gunpowder." ”

Do you think it's a firecracker, you have to see enough, Liu Yuan muttered while responding: "Yes, Your Majesty, Weichen will let them continue to blow up the stone mountain immediately." ”

"Wait" Li Er suddenly shouted, turned his head and said to the personal guard beside him: "Chen Feng"

"The end will be."

Li Er suddenly said with a straight face: "You do two things now, the first is to send a hundred more people to protect Liu Yuan's research institute, except for the general Liu Yuan, no one is allowed to enter or leave, and the second is to send a team of people to watch those slaves, especially the fire path of those gunpowder, to register in detail, even a little gunpowder, and it can't leak out. ”

These gunpowder are too dangerous, since they can blow up the stone mountain, it may also be used by unscrupulous people to blow up the palace, then it poses a great threat to the palace, Li Er doesn't want to sleep uncomfortably by himself, and immediately ordered these powerful things to be controlled in his own hands.

There are so many civil and military ministers here, but Li Er's most trusted personal guard sent him out, obviously out of safety considerations.

"Yes, Your Majesty, the little one will do it immediately" Chen Feng responded, immediately retreated, and then flew as if to carry out Li Er's order.

After the order, Li Er continued to say to Liu Yuan: "Okay, Liu Aiqing, you can continue now." ”

Liu Yuan nodded, and made a signal with the white flag in his hand in the air, signaling Tang Jin to continue to set fire to blow up the stone mountain, in addition to showing Li Er the power of the gunpowder today, blowing up the stone mountain, and the high belt road designed by himself passed the preparation from here, there is a saying, the road is through the wealth.

Under Liu Yuan's command, Tang Jin and the others continued to reload gunpowder non-stop, and began to carry out devastating destruction on the stone mountain that blocked Liu Yuan's advance.

"Boom!"

"Boom!"

"Boom!" "Boom!" "Boom!

Bursts of explosions, like a thunderclap, the sound of explosions, like a thunderbolt on a sunny day, the earth moved the mountains and mountains, as far as the eye can see, the exploding stones are flying all over the sky, and suddenly fall to the ground like a rain of stones, extremely spectacular, Li Er and others are happy to see one by one, and from time to time there are applause and cheers, like a little fart watching fireworks, that is, afraid of Wei Heizi, after overcoming the fear in his heart, he also covered his ears and watched with great interest.

I don't know how many times the stones were blown up, and there were no number of people who had a total of how many "stone rains", Li Er led his ministers to see the sunset all the time, so he reluctantly went home, but before leaving, Li Er ordered again, that is, the Yangwei Army and the forbidden army still blocked the scene until the mountain was blown up, and Liu Yuan, as the initiator, was also ordered to follow Li Er's team.

Enter the palace for secret talks.

Back in the palace, Li Er didn't eat, and immediately called Liu Yuan to the imperial study for questioning, this time he didn't even serve wine and pastries, and after clearing the palace maids and guards, Li Er couldn't wait to ask: "Liu Yuan, tell me quickly, how much stock of gunpowder do you have?" How many people know the purpose of gunpowder? And how many people know the formula of gunpowder? In addition to Tubo and this explosion of the rock mountain, have you used it for any other purposes? ”

Good guy, he asked several questions in one breath, but Liu Yuan didn't know which one to answer first, Li Er, who had already lost his temper. (To be continued......)
