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

The noise was obviously made by Gong Shucan and the others. When Gong Shucan came, he didn’t bring many people with him. Including him, there were ten people in total. Liu Tan glanced over and found that the people from the Mo family and the Gongshu family were evenly divided, and there were two other students. The face should not belong to the Mo family or the public loser.

Seeing that Gong Shucan is becoming more and more like a high-ranking person, he is relieved.

He didn't insist that Gongshu can repay grievances with kindness, not to mention that the entanglement between the Mo family and the Gongshu family for so many years was not something he could decide alone.

But he cannot represent the public loser in this seat, so he must be impartial.

If he can't even do the most basic justice, Liu Tan will replace him sooner or later.

Because this position is not for Gongshu Patriarch, but for capable Gongshu Charm.

Gong Shucan's role change was fairly smooth, he might not be too close to the Mo family, but he didn't suppress him too much, that's all.

After Liu Tan told them his request, Gong Shucan's eyes lit up. They Gongshu had always studied this kind of war equipment.

The Mohists might not like it very much, but these Mohist boys are still young, and when they are hot-blooded, when they hear that they are going to fight the Huns, they all feel like they have been beaten with chicken blood.

But the question is when will the tasks assigned by Liu Tan become easier?

Liu Tan didn't have time to draw a picture this time, but just wrote down all the principles in it, and then handed it over to Gong Shucan and the others. After all, as the leader of the whole army, he still has a lot of things to do.

Gong Shucan originally thought it was very simple. After all, the principle is here, so what is so difficult?

Then the reality gave him several slaps—the difficulty of the landmine lies not in the organization, but in the stability of the organization.

As Liu Tan said, what kind of touch can this organ withstand to explode?

In the beginning, Gongshucan set it to explode when people stepped on it, and the experiment went smoothly, but Liu Tan asked a very fatal question after seeing the mechanism they made: "During the process of carrying the mechanism, it will be destroyed. trigger?"

Gong Shucan was stunned for a moment, and tried it on the spot. Facts have proved that with the current transportation of human and animal power, the mechanism is likely to be triggered during this process.

Although it is not certain, but... Once one is triggered, it will be the rhythm of annihilation of the whole army, they can't be careless.

So they need to find a balance between the weight of the person and the collision during the handling process.

In this era, the analysis of gravity and force is in a relatively primitive and barren state. There may have been places where these things were involved before, but people today do not have this awareness and do not know what laws to summarize.

As for Liu Tan... It might be okay to ask him to invent things, but he has really lost all his high school physics knowledge. It is not as easy for him to help out as others rely on experience, and it is better not to intervene.

He simply ignored it, and ended up listening to the sound of explosions every day, thanks to the lack of black powder given.

However, the mechanism itself has nothing to do with the amount of black powder, what matters is the trigger device and lead wire, so the amount of black powder does not matter.

Liu Tan was a little worried: "I didn't expect it to be so difficult. If this goes on like this, the other party might find out soon."

Lu Xuan patted his head and said, "Don't worry, we can win even without minefields, I'll go first."

Liu Tan nodded and looked at him eagerly and said, "If you encounter danger, you must run first."

Lu Xuan was a bit dumbfounded for a moment, this was probably the first time someone told him to desert when he encountered danger. The education he had received from childhood told him that even if he encountered danger, he had to muster up the courage to face it.

He nodded: "Don't worry, I don't want you to cry, go away, if I come back late, don't wait for me, go to bed first."

Liu Tan was stunned for a moment, then pursed his lips, originally wanted to say that he didn't like to cry, but when he thought about if Lu Xuan was seriously injured... no, he couldn't think about it, his heart was about to twitch when he thought of this possibility.

Lu Xuan did not perfunctory Liu Tan, he did not plan to do dangerous things, mainly he wanted to use the binoculars to see what the other party was doing.

Because the telescope is too precious, there are not many people who are qualified to use it so far. Now there is no one else in the entire camp.

So if he really wants to use the binoculars, either he or Liu Tan will come. Liu Tan is worried about him, and he is even more worried about Liu Tan. He is especially worried that Liu Tan will find someone excited and call him.

Lu Xuan took advantage of the night and ran into the desert to cover himself and his men with sand. This is a concealment method often used in desert warfare, but this method... can deceive people at night, and it can't Get too close, or wait to be discovered.

So generally, the scouts sent out by these countries in the Western Regions are the ones with very good eyesight, otherwise, no matter how well concealed they are, it will be useless, and they will not be able to see the other party's situation at all. Isn't this a waste of time?

It's also fortunate that Lu Xuan has a binoculars in his hand, otherwise he would not be able to see clearly at this position even if his eyes are good, let alone at night.

He took a binoculars and looked at it for a while. The lights in the other side's camp were brightly lit, and he couldn't see anything special, but Lu Xuan believed that there must be something wrong with You Guduhou's lack of combat power, so he waited very patiently. They waited until the moon was in the middle of the sky, only then did they see a group of people sneaking out of the camp.

Lu Xuan's eyes lit up immediately, and after the team left, he got up and said, "Go, follow."

It's just that because of hiding for too long, and the low temperature in the desert at night, when he got up, he felt that his body seemed to be a little numb, and he even staggered a little.

However, he quickly adjusted himself and quietly followed with his hands.

With the telescope around, he didn't need to get too close at all, as long as he could ensure that the opponent was within the scope of the telescope's field of vision.

Then he saw that team of Turks ran to a place with slightly harder ground and stopped, and then... took out their shovels to dig!

When Lu Xuan saw it, he wondered if he had read it wrong. He looked carefully for a long time before he could confirm that the other party was really digging. What.

Lu Xuan originally wanted to arrest these people and ask them what they were doing, but he was afraid of scaring the snake away.

In the end, he decided to go back first. Anyway, looking at the other party like this, he must be working on some kind of project. It is impossible to finish it in a day or two. He can definitely bring the news to Liu Tan first. Anyway, his family is an expert in this area. It's probably useless for him to think for a long time here.

Lu Xuan made a gesture and led the people to evacuate the scene quietly. From the beginning to the end, the Huns didn't realize that their behavior was discovered, but that's true, how could they think that the Han people still have such a big killer in their hands? ?

Li Xi had used it before, but in Wuhuan's situation... it was really crushing, the opponent was defeated before he even found out the details of the Han army, so naturally he couldn't send any news.

It was early in the morning when Lu Xuan went back. Originally, he thought that Liu Tan was asleep and didn't want to disturb him. Anyway, he also had his own tent, so it was pure fun to huddle together with Liu Tan.

As soon as he entered the station, he asked everyone to keep their voices down so as not to disturb the King of the North, but when he walked to the door of the tent, he saw Liu Tan standing there in a cloak, waiting for him. up.

Lu Xuan's heart softened, and he hurriedly walked over and asked in a low voice: "Didn't I tell you to sleep first?"

Liu Tan yawned, with water in his eyes and said vaguely, "I'm worried if you don't come back."

He became more sober after speaking, a little strange, why didn't Lu Xuan come over to hold his hand today?

Lu Xuan seemed to like intimate actions such as holding hands and hugging. As soon as he approached Liu Tan, he subconsciously prepared, but the other party didn't move.

Liu Tan was shocked immediately, thinking that the other party was injured, he quickly grabbed his hand and asked, "Why..."

Before he finished speaking, he knew why Lu Xuan didn't hold his hand, because Lu Xuan's hand was so cold that Liu Tan even thought he was holding a piece of ice.

Seeing his wide-eyed eyes, Lu Xuan pulled out his hand and said, "Wait a minute, I'll warm it up."

Liu Tan felt distressed: "Don't you know it's cold at night? Why don't you wear more? Didn't you wear a woolen sweater?"

Lu Xuan followed him into the tent and said, "I'm wearing it, but it's just that I can't move for a while, and I don't have any activities."

And it is still buried in the sand, which is even cooler.

As for wearing more... Where do scouts wear so many?It is easy to be found, and it is not easy to run when running.

Liu Tan didn't even bother to ask him what he found, and hurriedly dragged someone in to warm up.

After settling down in the tent, Lu Xuan narrated everything he saw.

Liu Tan had a big brain, so he smiled immediately without any analysis: "They want to imitate me."

Lu Xuan asked doubtfully while drinking hot water: "What did you learn from you?"

Liu Tan said: "Didn't I dig a tunnel in Shanggu City back then? It was because of this that I caught the opponent by surprise, and then captured Zuoguduhou. This time, Rightguduhou probably wanted to do the same."

Lu Xuan suddenly felt as if he was facing a big enemy: "Then should we change places?"

Liu Tan raised his chin slightly: "Let him dig for a year and a half, and he will probably be able to dig it out."

Where is this?This is the Gobi, either gravel or hard rock. Liu Tan used black gunpowder to dig on the ground. Their manual digging... is really whimsical.

Lu Xuan felt relieved after listening to Liu Tan explain the cause and effect, touched his chin and said, "Maybe we can take advantage of it."

Liu Tan lowered his head and pondered for a while and said, "Is the place where they dug the tunnel far from their camp?"

Lu Xuan thought for a while and said, "Not far."

Liu Tan said with a smile: "Then let's treat him with his own way. When it comes to digging tunnels, we are the ancestors!"
