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

Liu Tan once thought about hand crossbows when Spring Hunting was forced to cheat, but quickly gave up the idea.

In terms of lethality, the hand crossbow is indeed relatively high, but the problem is that the range of the bow depends on the strength of the human arm, and the range of the crossbow depends largely on its size.

In fact, there are crossbows now, but they are called crossbows. The heavy cavalry of the Han Dynasty are equipped with crossbows.

This is why the heavy cavalry of the Han Dynasty can resist the light cavalry of the Huns.

But if you want to change the stepping crossbow into a hand crossbow, then there is no such range.

The range of the hand crossbow is very short, within 200 meters, it is the king among cold weapons, and it is a chicken beyond 200 meters, not as good as a bow and arrow.

However, regardless of any weapon, it is necessary to distinguish the occasion of use. If you use the place, it will naturally get twice the result with half the effort.

After discussing the case, Liu Tan decided that it was time for the Gongshu family to do some activities.

Before the Gongshu family sent people to follow him all the way to the northern border country, the adjustment buttons of the sights and the like were also done in the northern border country. Before that, Liu Tan was busy with other things and had nothing to look for them. I don't know. What about the members of Gongshu's family?

He thought about it for a while and asked someone to notify the members of Gongshu's family, and explained his request. The most important thing about hand crossbows is that they are portable, so the size should not exceed half an arm. On this basis, how far the shooting range counts How far.

Liu Tan has finally discovered the benefits of having these institutions and families. He doesn't need to learn from scratch. He only needs to make it and then see what is not good enough, and then make improvements.

As he thought about it, he wrote down his requirements. The above requirements are actually good. They are nothing more than letting the public losers shrink the crossbow and make it usable by one person. He simply set a few more specific standards, and by the way Best to have them make arm crossbows if they can.

After finishing writing, he himself felt that these requirements were quite devilish.

Think about it, if he was Party B and met such Party A, he would almost commit suicide every minute.

However, he is now a stress-free party A, and he is very happy to order the request, without having to meet the public loser in person.

However, in order to prevent the public losers from defecting in anger, Liu Tan specially ordered: "The public losers can do or not do this matter, let them figure it out for themselves, my requirements are clearly written here. "

Miao Rui said: "Your Highness is good at everything but too kind, how can they say no?"

Liu Tanxin said, don't underestimate the abilities of these technology emperors. If the business is not successful, there is still righteousness. If you like to do it or not, if you don't do it, he can do it himself. If these people are forced away, they will go to other princes or kings. It's fine to go back to Chang'an, if he runs to the Xiongnu in a fever, he has nowhere to cry.

It's just that Liu Tan thought a lot, but didn't think about the enthusiasm of Gongshu's family who had been holding back for a long time.

These people can be regarded as capable people in the family, and the owner of the public loser will definitely not easily talk to Liu. The habit of their family has never been to put all their eggs in one basket.

For the princes and kings who are worthy of investment, then send more capable people from the family. If it is useless or does not pay attention to mechanism skills, then just send a side disciple to see if there is any opportunity.

But the head of the Gongshu family has always stayed in Chang'an.

These children of the Gongshu family had homework to do every day when they were in Chang'an, and things like mechanism skills also pay attention to a touch, and they often do it by hand without doing it.

As a result, after they arrived in the northern border country, apart from being a sight, the king of the northern border seemed to have forgotten them.

Oh, they were given a lot of rewards after completing the aiming device, and those rewards were even enough for their children to buy a large piece of land in Shuofang City to build their own houses.

Except for this, they have nothing to do every day. When they have nothing to do, they start to study whether to put some traps in the house, and then what kind of traps they want to put.

They had already quarreled a lot because of this nonsense, and finally decided to put the mechanism in the place where the books and some mechanism parts were stored, and each person's room decided for himself.

Then there is a discussion about what institutions are stored in the study and warehouse.

It's a discussion, but it should be considered a competition. Everyone thinks that the mechanism they designed is the best, so let's just install it and have a look.

The children of the Gongshu family who lead the team this time are not too old. Gongshu is also 30 years old, but they obviously can't suppress these younger brothers and sisters. Fortunately, Liu Tan has a new mission, otherwise he feels that they will be sent by the Gongshu family in a few days. people will have non-combat attrition.

Yu Liutan's requirements are strict, and Gongshu is even more happy to see that, anyway, those little bastards are more energetic than each other, aren't you amazing?Aren't you disobedient to anyone?Come on, give you a chance to play.

Gongshu also pleased to announce the request and said: "You guys have to think about it, this is the first thing the king of the northern border asked us to do since we arrived in the northern border country. If it goes wrong, the king of the northern border will not be happy. , my family will definitely be punished, maybe you will die of old age here in the future."

Gongshuyi's younger brother, Gongshulang, whispered, "I think Shuofang City is much better than Chang'an City."

Gongshu raised his hand expressionlessly and patted Gongshulang on the head: "What's the matter? Fortunately, parents are not here and can't control you, can they?"

Gongshu Lang chuckled, and their cousin next to them was a very lively little lady, and said at this time: "Although Shuofang is not as prosperous as Chang'an, the people here are much better."

Gongshu didn't say anything, he knew what his cousin meant.

The water in Chang'an City is very deep, and the people passing by on the road may be the family members of some high-ranking officials and nobles. Everyone must be careful in their conduct, and there are often those who praise the high and step down. More than enough, but not without being despised.

Even if they help others, many people think that they are asking for something from themselves, and they all take it for granted.

But Shuofang City is different. The people here know how to be grateful, and they are especially tenacious. The most important thing is that the King of the Northern Realm has too many whimsical ideas. The newly built capital of the king looks more orderly and clean than Chang'an.

Gongshu also liked Shuofang City more than Chang'an.

"Since you all like this place and want to stay here, then work hard. If you can't do this, even if His Royal Highness the King of the North doesn't blame us, do you still have the face to stay here?"

The others thought about it for the same reason. This was their first mission after arriving in the Northern Borderlands.

So the public loser was rarely quiet, waiting for the public loser to assign tasks to them.

After Gongshuyi read all Liu Tan's request, the audience fell silent for a moment. Everyone looked at each other, and they all saw confusion from Fang's eyes.

Gongshu also asked with a smile: "What's the matter? Why are you all wilting? Didn't you just gear up and try?"

Gongshu Lang scratched his head and said, "I know about the crossbow, but... I haven't learned how to do it. Brother, have you ever learned it?"

Gongshu Yi's smile suddenly froze on his face, so here comes the problem... He hasn't learned it either!

It is said that the Gongshu family's mechanism technique is very aggressive. In fact, the great Han has been in power for so many years, and they rarely have access to this kind of weapon mechanism.

As far as the folks are concerned, you can have swords and bows, but you must never have a crossbow. As long as you find it at home, you will be counted as treason.

Those who can make and repair crossbows are official craftsmen, the kind of slaves who are usually under strict supervision.

No matter what, the Gongshu family has never been reduced to the point of being slaves, so basically not many people in the Gongshu family know how to make a crossbow.

Those who are public losers dare not teach their children these things. If they teach them, and then the children do something out of nowhere, it will be the rhythm of Zhu Jiuzu.

Gong Shulang said: "The Zangshu Pavilion in my family should still have the blueprint of Qin Nu, maybe..."

Gongshu also shook his head and said: "Don't say whether the family is willing to give us the blueprint, just say that the distance is so far away, it takes a lot of time to go back and forth, it's not good to make His Royal Highness the King of the Northern Realm wait, let alone the fact that there will be no blueprints along the way. It's safe, if someone robs and uses it, then we all apologize with death is not enough to quell the matter."

The little lady Gongshu said: "In that case, then go and ask Your Highness to ask His Highness General Zhong Ta Nu to show us, otherwise we don't even know how to make a Ta Nu, so how can we make a hand crossbow?"

Gongshu was also a little worried: "That's the only way."

He turned his head and carefully talked to the internal officer in the palace who was in contact with him.

The internal officials treated them well, but they didn't agree, they just said that they would apply.

After all, the stakes are high.

Liu Tan also didn't expect that people from the Gongshu family would not be able to make crossbows, but it's not surprising after thinking about it. He hesitated and said, "You can show them, but from now on, people from the Gongshu family will be restricted from entering and leaving the northern border country." , you must have a legitimate reason and get permission before you can, and you can’t leave together, if they can agree, let them watch.”

Liu Tan was also worried that the people who turned back to losers would pass on the making method of the crossbow after watching the crossbow.

The Huns may not need to make crossbows. Their strengths lie in light cavalry. It is impossible for them to abandon their own characteristics to learn from big men, but they can completely find the shortcomings of crossbows after they know the technological process of crossbows.

They don't have to learn, they just need to be able to destroy.

Gongshuyi and the others agreed happily, and they were all very housebound, except for buying necessary daily necessities and materials, each of them could not leave the house for many days.

Liu Tan's request was nothing to them.

After they agreed, it was natural to arrange for them to visit Ta Nu.

Liu Tan was curious and followed to have a look.

It was the first time for the members of Gongshu's family to see Liu Tan, and they didn't pay much attention to Liu Tan except for the good looks of Wang Sheng in the Northern Territory. In their eyes, Ta Nu was probably more beautiful than Liu Tan.

However, after seeing the crossbow, they all fell silent. Today's crossbow is about one person tall. How can such a giant be reduced to the size of an arm?The most important thing is that the force of stepping on the crossbow lies in the stepping on the foot to launch, that is to say, the crossbowman basically exerts force all over his body when launching.

As for the hand crossbow, even with that size, it is impossible to force the whole body, so the entire firing method must be changed accordingly.

So the question is what launch method to use?

After Liu Tan walked around the crossbow for a while, he stretched out his hand and flicked the bowstring of the crossbow, just in time to hear the way Gongshuyi and the others were firing the crossbow. gone?"

The members of Gongshu's family immediately looked up at him together, and Gongshu even asked, "Your Highness, what is a trigger?"

Liu Tan was stunned, and then remembered, oh, there hasn't been a trigger these days.
