I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Lu Xuan looked at Liu Tan in a daze: "Landmine? What is that?"

Liu Tan thought for a while and said, "It's a variant of the powder keg. You can just bury all the powder kegs underneath, and when they pass by, it will explode, and then..."

Lu Xuan has not fully experienced the power of the gunpowder barrel, but out of trust in Liu Tan, he still nodded and said: "If you are sure, you can try it."

After Liu Tan heard it, he felt a little stuck for a moment. He laughed dryly and said, "I'm sure, that's..."

Lu Xuan tilted his head and looked at him: "Huh?"

Liu Tan said embarrassedly, "It's just that the landmines haven't been researched yet."

Lu Xuan was a little dazed: "According to what you mean, don't you just bury the powder kegs underneath?"

Liu Tan explained: "That's a short way of saying that the powder keg needs to be ignited to explode, but since it's a trap, it's impossible to arrange someone to ignite it, otherwise the opponent's scouts will easily find it."

Seeing that he didn't look embarrassed when he said it, Lu Xuan said firmly, "You already have a solution."

Liu Tan nodded: "Yes, use the steel wheel to fire the mechanism, but this mechanism needs to be studied."

The so-called steel wheel ignition mechanism is actually the kind used in iron shell landmines. After the mine encounters vibration or pressure, the steel wheel inside rotates and rubs against the flint sharply to generate sparks and then ignites the fuse.

This mechanism is relatively simple, after all, if you want to make a more complicated mechanism now, you can't do it.

The only trouble is how to control the mechanism. After all, it is triggered by vibration or pressure. So you need to be careful when the vibration or pressure is triggered. Don’t touch the mechanism when you turn around to transport the mines, and blow up your own people. That would be a major accident.

Liu Tan asked Gong Shucan to bring someone over quickly. He didn't specify who the other party would bring, he took anyone he wanted, but it had to be someone who had experience in researching gunpowder, and anyone without experience would not do.

Gong Shucan has been rather boring recently. His Royal Highness the King of the North is not here, so he feels like doing nothing is interesting. He also has various researches in his hand, but those studies that can arouse his interest in the past are compared to what the King of the North often asks him to do. Those novelty gadgets are very dull.

He also thought about creating something new by himself, but limited by his growth environment or vision, the ideas he could think of were not interesting, and the most important thing was that they were not very practical.

Now that he heard that the King of the Northern Territory had summoned him, Gong Shucan immediately had someone pack up his things and rush over quickly, as if he wanted to grow two wings on his body.

When Gong Shucan arrived there, the big man and the Huns had already started small-scale contact and started fighting.

Liu Tan didn't intend to just wait for him like that. With so many of them, the fact that the Xiongnu didn't find out at the beginning doesn't mean they never found out.

Once you find out that the other party comes to attack them, what should you do?Before Liu Tan was worried that after the fight, the other party would run away when they saw so many of them.

Lu Xuan is not worried: "Don't worry, even if the Huns find out that there are many people on our side, as long as they don't disclose the news that I'm here, they won't run away immediately."

Liu Tan was a little puzzled: "Ah? Do they still dare to fight? We have many more people than them."

Lu Xuan said very bluntly: "No matter how many big men there are, they haven't lost before. They still have confidence in themselves now."

Liu Tan looked incredible: "They still dare to have confidence when I'm here?"

Lu Xuan thought about it for a while and didn't have the nerve to hit him. He just said: "After all, you won against Wushilu before. After Xiaolihu came to power, he tried to smear Wushilu, so everyone thinks that he lost to you because he was incompetent, and the Xiongnu Except for a little loss at your hands, haven't you lost all the recent battles?"

Liu Tan raised his head and thought about it for a while, and then he remembered that the last time the big man fought with the Xiongnu was in collusion with Captain Zuo. .

Thinking of this, Liu Tan felt a little bad all over, and said angrily: "Dare to underestimate us, don't they know how Wuhuan destroyed the country?"

Although many Wuhuan people are still alive, the country is indeed gone, so there is no problem in destroying the country.

Seeing him like this, Lu Xuan couldn't help pinching his face, and said with a smile: "Well, they are blind, but Wuhuan is nothing in their eyes."

In fact, just like the big Han, in the eyes of the Han people, their biggest enemy is only the Huns, and other small countries can only be regarded as provocations, and it depends on whether the big man wants to deal with them.

Isn't Wuhuan a good example this time?As long as the big man wants to fight, these small countries will have no power to fight back.

The Huns are the same, even the Huns are more confident than the big Han. In the past, those countries in the Western Regions looked up to the Huns, and at most they were polite to the big Han. Wuhuan didn’t have much contact with the Huns, but they were forced to go directly to the Huns for help. It can be seen that they are the only ones who can compete with the big man.

So even if Wuhuan destroyed the country, the Xiongnu would not have any vigilance.

After all, in the land of the Western Regions, a small country would be wiped out almost every once in a while, and everyone was used to this kind of thing.

Liu Tan pursed his lips, thinking of what Lu Xuan said just now, turned his head to look at him and smiled, "So you think you are more deterrent than my soldiers?"

Although Lu Xuan already has a good understanding of the Central Plains culture and uses it well, but because of the environment in which he grew up, he probably never knew what it is to be modest, and said very frankly: "No matter how many people there are in an army of [-], If there are no good generals, it is a mess and can only be slaughtered by others."

Liu Tan rolled his eyes: "Pay attention to your words, I'm still here."

Lu Xuan looked at Liu Tan aggrievedly, this...it's really hard to say, the Huns are indeed afraid of the Northern King, but the problem is that what they are afraid of is not the Northern King's ability to lead troops to fight, but the Northern King's fear King's... witchcraft.

Yes, several times, they always lost inexplicably against the King of the Northern Realm, and every time the opponent could come up with very strange things that made them unable to deal with it.

So as long as Liu Tan doesn't come up with new things and is simply a commanding general, the Huns may not be afraid.

However, Lu Xuan didn't dare to tell the truth, he was afraid that if he told the truth, he wouldn't be able to hug his wife to sleep.

Liu Tan was also very clear in his heart, snorted and waved his hands and said, "You are so clear in your heart, why don't you rush to arrange it? If you don't arrange it well, I will punish you."

Lu Xuan smiled, took advantage of no one else in the tent leaning up to hug his waist, stole a kiss and said in a protracted tone: "Yes~"

And Youguduhou was also taken aback when he heard that the big man had an army of [-] coming. He was already prepared to escape, but when he heard that the leader was the King of the Northern Territory, the greed in his heart Gained the upper hand——If the King of the Northern Territory can be captured alive, then Shan Yu must be very happy.
