Chapter 647 [Three Updates]
The noise was obviously made by Gongshu Can and his men. Gongshu Can didn't bring many people with him when he came, only ten people in total including him. Liu Tan took a quick look and found that the people from the Mohist School and the Gongshuist School were half and half, and there were two unfamiliar faces, who were probably neither from the Mohist School nor the Gongshuist School.
Seeing that Gongshu Can was increasingly acting like a superior, he felt relieved.
He did not force Gongshu Can to repay evil with virtue, and besides, the entanglement between Mohism and Gongshu Can for so many years was not something he could decide alone.
But if he sits in this position, he cannot represent the public loser, so he must be fair.
If he can't even achieve the most basic fairness, Liu Tan will replace him sooner or later.
Because this position was not given to the head of the Gongshu family, but to the capable Gongshu Can.
Gongshu Can's role transition was relatively smooth. He might not be too close to the Mo family, but he didn't suppress them too much either. That was enough.
After Liu Tan told them his requirements, Gongshu Can's eyes lit up. Their Gongshu family has always been quite knowledgeable about this kind of war equipment.
The Mohists might not like it, but these Mohist guys are still young and full of passion. When they heard that they were going to be used to fight the Huns, they all became excited.
But the question is, when has the task assigned by Liu Tan ever been simple?
Liu Tan did not have time to draw a picture this time. He just wrote down all the principles and then handed it to Gongshu Can and others. After all, as the leader of the entire army, he still had a lot of things to do.
Gongshu Can originally thought it was very simple. After all, the principles were all there, so what could be difficult?
Then reality slapped him in the face several times - the difficulty of the mine was not the mechanism, but the stability of the mechanism.
As Liu Tan said, what kind of trigger would make this mechanism explode?
Initially, Gongshu Can designed the device to explode if someone stepped on it, and the experiment went smoothly. However, after Liu Tan looked at the mechanism they had built, he asked a crucial question: "Will the mechanism be triggered during transportation?"
Gongshu Can was stunned for a moment and tested it on the spot. It turned out that with the current transportation by human and animal power, it is very likely to trigger the mechanism during this process.
Although it is not certain, but... once one is triggered, the entire army will be wiped out, so they cannot be careless.
So they need to find a balance between the weight of the person and the collision caused during the transportation process.
In this era, things like gravity and force analysis are still in a relatively primitive and barbaric state. These things may have been involved in some places before, but people nowadays do not have this awareness and do not know what rules to summarize.
As for Liu Tan...it might be okay to let him invent something, but he has really forgotten all the high school physics knowledge. It would be harder for him to help than for others to rely on their experience, so it would be better for him not to get involved.
He simply ignored it, and ended up hearing explosions every day, all because he wasn't given enough black powder.
However, the mechanism itself has nothing to do with the amount of black powder. What matters is the trigger device and fuse, 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, the other party might find out soon."
Lu Xuan patted his head and said, "Don't worry. We can win even without the minefield. I'll go first."
Liu Tan nodded, looked at him eagerly and said, "If you encounter danger, you must run away first."
Lu Xuan was at a loss for words for a moment. This was probably the first time someone told him that he should desert when faced with danger. The education he received since he was a child had always told him that even when faced with danger, he should muster up the courage to face it.
He nodded: "Don't worry, I can't bear to see you cry. I'm leaving. If I come back late, don't wait for me. Go to sleep first."
Liu Tan was stunned for a moment before pursing his lips. He wanted to say that he didn't like to cry, but when he thought about what if Lu Xuan was seriously injured... No, he couldn't think about it. His heart was in a knot when he thought about this possibility.
Lu Xuan didn't give Liu Tan a perfunctory response. He really didn't intend to do anything dangerous. He mainly wanted to use the telescope to see what the other party was doing.
Because the telescope is so precious, there are not many people who are qualified to use it so far. Now in the entire camp, there is only Liu Tan and him, and no one else.
So if they really want to use the telescope, either he or Liu Tan will come. Liu Tan doesn't trust him, and he is even more worried about Liu Tan. Especially he is worried that Liu Tan will find out something and get excited and attack with others. What if?
Lu Xuan took advantage of the night to run into the desert and covered himself and his men with sand. This was a common concealment method used in desert battles, but this method... could only deceive people at night, and one couldn't get too close, otherwise they would be discovered.
Therefore, generally speaking, the scouts sent out by these Western Region countries are those with particularly good eyesight. Otherwise, no matter how well they hide, it will be useless because they cannot see the other party’s situation at all. Wouldn’t that be a wasted trip?
Fortunately, Lu Xuan had a telescope in his hand, otherwise he would not be able to see clearly from his current position even if his eyesight was very good, not to mention it was at night.
He used the telescope to look for a while. The enemy camp was brightly lit, but he could not see anything special. However, Lu Xuan was sure that there must be something wrong with the lack of fighting power of Yougudu Hou's men. So he waited very patiently until the moon was at its zenith, and then he saw a group of people sneaking out of the camp.
Lu Xuan's eyes lit up immediately. After the group left, he stood up and said, "Let's go, follow them."
It was just that because he had been hiding for too long and the temperature in the desert was low at night, when he got up he felt his body was numb and he even staggered.
However, he quickly adjusted himself and quietly followed with his men.
With the telescope, he doesn't need to get too close, as long as he can ensure that the other party is within the field of view of the telescope.
Then he saw the team of Turks run to a place with slightly harder geology and stop, and then... took out shovels and started digging!
When Lu Xuan saw this, he suspected that he had seen it wrong. He looked carefully for a long time before he was sure that the other party was really digging the soil. He was confused for a moment and had no idea what the other party was doing.
Lu Xuan originally wanted to arrest these people and ask them what they were doing, but he was afraid of alerting the enemy.
Finally, he decided to go back first. Judging from the other party's appearance, they must be working on some project, which would not be completed in one or two days. He could just bring the news to Liu Tan first. After all, his Tan was the expert in this area, and it would be useless for him to think about it here for a long time.
Lu Xuan made a gesture and led his men to quietly evacuate the scene. From beginning to end, the Xiongnu people did not realize that their actions had been discovered. But then again, how could they have imagined that the Han people had such a powerful weapon as the telescope?
Li Xi had used it before, but the situation with the Wuhuan... was truly a crushing defeat. The enemy was defeated before they could even figure out the details of the Han army, so naturally they couldn't send out any information.
It was already early morning when Lu Xuan returned. He had thought Liu Tan was asleep and didn't want to disturb him. He had his own tent anyway, so squeezing in with Liu Tan was purely for fun.
As soon as he entered the camp, he asked everyone to keep their voices down so as not to disturb the King of the North. However, when he reached the door of the tent, he saw Liu Tan standing there in a cloak waiting for him, with his eyes half closed, and it was obvious that he was very sleepy.
Lu Xuan's heart softened, and he quickly walked over and whispered, "Didn't I tell you to go to sleep first?"
Liu Tan yawned, his eyes glistening as he mumbled, "I won't be worried if you don't come back."
After he finished speaking, he became more sober and a little puzzled. Why didn't Lu Xuan come over to hold his hand today?
Lu Xuan seemed to like intimate gestures like holding hands and hugging. As soon as he got close to Liu Tan, he subconsciously prepared himself, but the other party didn't move.
Liu Tan was startled, thinking that the other party was injured, and quickly grabbed his hand and asked, "What's wrong..."
Before he finished speaking, he knew why Lu Xuan didn't hold his hand, because Lu Xuan's hand was very cold, so cold that Liu Tan even thought he was holding a piece of ice.
Seeing his eyes widen, Lu Xuan pulled his hand away and said, "Wait a moment, I'll warm it up."
Liu Tan was so distressed: "Don't you know it's cold at night? Why don't you wear more clothes? Don't you have a woolen sweater?"
Lu Xuan followed him into the tent and said, "I've put it on, but I haven't been able to move around much for a while."
And it was buried in the sand, which made it even colder.
As for wearing more... How can a scout wear so much? It's easy to be discovered, and it's hard to run.
Liu Tan didn't even bother to ask him what he had discovered, and hurriedly dragged him in to warm up.
After settling down in the tent, Lu Xuan told everyone what he had seen.
Liu Tan had a rather creative mind, so he immediately laughed without needing to analyze, "They want to imitate me."
Lu Xuan drank the hot water and asked in confusion, "What do you mean by learning from me?"
Liu Tan said, "Didn't I dig a tunnel to get into Shanggu City? That's how I caught them off guard and captured Zuogu Duhou. I think Yougu Duhou is planning to do the same this time."
Lu Xuan suddenly felt as if he was facing a formidable enemy: "Should we change places?"
Liu Tan raised his chin slightly and said, "Let him dig for a year or two and he'll probably be able to find it."
What kind of place is this? This is the Gobi Desert. It's all gravel and hard rock. Liu Tan used black powder to dig in the ground back then. Their manual digging... what a fantasy.
After listening to Liu Tan's explanation of the whole process, Lu Xuan felt relieved. He stroked his chin and said, "Perhaps we can make use of it."
Liu Tan lowered his head and thought for a while before saying, "Is the place where they dug the tunnel far from their camp?"
Lu Xuan thought for a moment and said, "Not far."
Liu Tan laughed and said, "Then let's give them a taste of their own medicine. When it comes to digging tunnels, we are the ancestors!"
