The country sends a daughter-in-law? Come and take a dozen, take them all

Chapter 137 Hasty retreat

Another option is to bury the bomb underground, and then use other thunder bombs to detonate it, which will definitely blow up the opponent's momentum.

However, it is a pity that once the two close combatants exchange hands, or the opponent's formation is dispersed, the effect of the bomb will be much smaller. Moreover, the method of laying landmines can only be used to blow up the opponent's leading troops.

Moreover, his production success rate is also very low. The output of gunpowder is not enough, so he has to be extremely economical when fighting.

It seems that there is still a long way to go before we can have a perfect bomb.

"Brother Lin, what is the slingshot you are talking about?"

Jian Bai heard another word he had never heard before and quickly asked.

You know, everything Lin Xiaofan talks about that he has never heard of can bring surprises to him.

For example, that repeating crossbow, and another example is this Lei Zhenzi.

Lin Xiaofan was slightly stunned. He didn't expect that this world didn't even have slingshots.

"A sling, a weapon of war."

He picked up a piece of charred wood and started drawing on the snow. Soon a sling map was drawn. Although it is somewhat abstract, the general structure is still there.

He was more interested in ancient weapons such as crossbows and slings in his previous life, so he knew their general appearance, production methods, and principles of use.

"The trebuchet uses a lever principle to throw the bomb to the opposite side at an extremely long distance."

After listening to Lin Xiaofan's introduction, Jian Bai was even more confused.

I have never heard of the leverage principle.

But thinking that this was Lin Xiaofan's master's skill, he forced himself to cheer up and not let go of every word Lin Xiaofan said next.

"Make a spoon shape on the right end of the log to place the thunderbolt. Hang some heavy objects under the left end of the log. At this time, this end of the heavy object will fall down."

Lin Xiaofan lightly tapped on the wood on the side.

Jian Bai nodded, he could easily understand these common sense.

"Pull down the end of the thunderbolt and tie it to the ground. At this time, just cut off the heavy rope hanging at the other end, and the end of the thunderbolt will be thrown out, thus throwing the thunderbolt out."

Lin Xiaofan gestured at the catapult painted on the ground. He was not stupid, and after listening to Lin Xiaofan's explanation, he quickly understood.

But soon, he shook his head:

"Brother Lin, our country's craftsmen once thought of this method, but they failed in the end and were beheaded by His Majesty."

"At that time, a craftsman in the country thought of using this method to throw huge rocks and hit the opposite camp. At that time, most of the civil servants and generals thought it was feasible, and spent a lot of manpower and material resources to implement it, and finally made this catapult. But it was very difficult. Soon, everyone discovered the problem."

"If you want to throw it far, then the weight of the suspended weight must be large enough. But if this is the case, firstly, the benefits brought are too small, and thirdly, even if the suspended heavy object reaches the endurance limit of the wooden pole, it cannot be thrown How far."

During a siege, this sling can only hit the city wall. When defending a city, using this so-called slinger would be better than just throwing stones at the bottom of the city.

I remember that at that time, there was a lot of uproar in the capital because of this matter, and he also paid attention to it.

But in the end, it was discovered that this method was of no use at all. Seeing that the quarrel for so long had no effect, the emperor chopped off the craftsman's head in anger.

Lin Xiaofan nodded after hearing this.

The craftsman who could think of such a method was definitely a talent. It's a pity that the emperor is stupid and acts on his own initiative, so he killed such a person.

"Brother Jian, don't worry, I haven't told you the principle of leverage yet."

Lin Xiaofan smiled confidently, and then said: "Normally, it can't be thrown very far. But if the support point of the wood is moved towards the heavy object, the distance of the launch will be several times further than before. This is The principle of leverage.”

"Ah? How is that possible?"

Jian Bai was stunned for a while after hearing this.

Just by changing the support point, can the throwing distance be increased several times?

If someone else told him this, he would definitely think that person was talking nonsense or was a lunatic.

Even if Lin Xiaofan said it, he subconsciously denied it.

To make Lei Zhenzi, three materials are used to fuse with each other. You can change the supporting points. Without adding any materials, you can throw the stone many times farther than before. Is this possible?

"Let's go back first and I'll explain this to you in detail."

Lin Xiaofan still didn't believe it when he saw Jian Bai, so he decided to go back and talk to Jian Bai in detail.

If you give Jian Bai a vague theory, I'm afraid Jian Bai won't be able to understand it. Only by giving him some practice, such as a seesaw, can he understand the truth.

Jian Bai also nodded. Because he was eager to see what explanation Lin Xiaofan could give, both of them moved very quickly.

I walked past the place where the guards trained, but didn't find them.

What happened? Where did he go?

Lin Xiaofan stood at a high place and saw a group of escorts rushing towards them. They were supporting each other and were still panting.

"What's going on? What kind of training are you doing?"

When they came up, Lin Xiaofan spoke in confusion.

It's strange, just now I saw them practicing swordsmanship with great energy, why did they become like this all of a sudden?

"Brother Lin, don't mention it. There was a bang just now. We thought there was an avalanche, so we hurriedly led the people away."

Song Shang sat down on the ground and spoke breathlessly.

When he joined the army before, he also encountered an avalanche. The scene was really terrifying. At that time, large snowflakes rushed over like a flood. Of the thousands of troops, only three or four hundred people survived. That avalanche also left a psychological shadow on him.

Today, he suddenly heard a blast, there was no thunder in the sky, and there was snow everywhere, so he subconsciously thought that there was an avalanche, and the people leading the escort team hurriedly evacuated.

But it’s wrong to think about it. This mountain is not high. Where did the avalanche come from?

"Haha, Brother Song, that's not an avalanche, it's the sound produced by the explosion of the explosive thunderbolt we developed."

Jian Bai couldn't help laughing when he saw Song Shang's frightened look.

Just now, this group of people were clamoring that they had seen everything and would not be frightened at all, but now everyone was in shock.

"what?"

"You guys made this up?"

"How is this possible? How can people make such a big fuss?"

"Brother Jianbai, did you cut off the mountaintop with one sword?"

When everyone heard this, they were all in a state of confusion.

They thought God was angry, but they never expected that it was Lin Xiaofan and Jian Bai who caused the disturbance.

Lin Xiaofan looked at everyone's appearance and shook his head slightly.

It's not surprising that everyone is like this. They have never seen gunpowder and it is difficult to understand why something can make such a loud noise.

"We are just experimenting with explosives. We may make this noise often in the future. Don't panic. Just train normally."

Lin Xiaofan said.
