South Korea's [Seven Wrought Iron] skills may be able to meet the needs of daily farming tools, but it is far from meeting the requirements of weapons manufacturing in Han Fei's mind.

Nowadays, the weapons in the new army are the armaments of the border army, and they use the skill of [Seven Wrought Iron], and there is a great need to replace this hardness of iron weapons such as Ge and spears.

Therefore, Han Fei's temporary armament plan for the new army was only placed on the [bow and crossbow], because the bow and crossbow did not need much iron, and South Korea produced more mulberry wood.

In particular, in the straight road from the iron mine to the foundry, a large number of aged mulberry wood was found in the primeval forest, and the bow and crossbow body made of this material was excellent in terms of hardness and toughness.

As for the Ge Spear and Long Sword, Han Fei planned to wait until after the New Year's Pass, and the foundry broke through the [Ten Wrought Iron] technical barriers before building it.

Anyway, Han Fei also came up with the method of mold manufacturing, and he is not afraid of how slow the time is to produce standard weapons.

After determining the direction, Han Fei wanted to start the development of weapons immediately.

The establishment of the new army is a national disaster for South Korea and Africa against the troubles that will soon break out in the western border of South Korea.

In the past few days, Xincheng has received a lot of people from the south of South Korea, and some of them are directly from other Chinese people who have fled here, and they have also brought relevant news to Han Fei.

The bandit army is divided into leather armor soldiers and cloth soldiers, leather armor soldiers are equivalent to regular army, and cloth clothes soldiers are slave soldiers, leather armor soldiers often have a bronze leather armor on their bodies, and there is a decent bronze weapon in their hands, but the cloth clothes soldiers are ragged, and even the weapons in their hands fighting on the battlefield are a simple wooden stick.

And if Han Fei wants to restrain them from winning with [crowd tactics], he must develop long-range attack weapons.

For example, bows and arrows, crossbows are the weapons of choice that Han Fei values, and because of the discovery of a large number of mulberry trees, there is no big problem with the strong bow.

The world's best crossbows are all from Han!

The development of crossbows in Korea is famous among the princes of the Central Plains, and Han Fei is also tested from a repaired crossbow, and the Han crossbow can indeed reach a range of 600 steps.

However, Han Fei relied on his memory of traveling around the heavens to draw the structural pattern of the crossbow, among them, the bow arm and crossbow body are made of mulberry wood, the string is made of twine soaked in tung oil, and as for the central cardinal, it is nothing more than to pull down the hanging knife, make the crossbow teeth shrink, dehook the string, and shoot arrows.

The crossbow body needs a greater pull, obviously, this pull is not manpower, but gear, which requires the use of molds to create iron gears, after all, although mulberry wood is hard, but after all, it is wooden, easy to be deformed by force, and there is no hardness of iron.

Thinking of the gear, Han Fei picked up the charcoal in his hand, which was wrapped in cloth for use as a pen, after all, when it came to composition, the brush was really a little powerless.

The first gear should have a handle, placed on the outside of the crossbow, which is turned by human power to pull the hooked teeth to the back, and for maximum labor-saving structure, three to five gears should fit inside the crossbow......

"No, no, no......" Han Fei shook his head, according to the technology of today's foundry, I am afraid that it will not be possible to make gears as thin as money lips, it is estimated that the size will be larger, plus the turn of the handle, the five gears will be more than thirty catties, and the entire crossbow will also reach nearly fifty catties, which is not a good thing.

Han Fei thought about it, and he could change the body of the crossbow machine to be thinner and call it two gears.

The wound tooth is pulled by a gear to the rearmost crossbow mouth, and the hooked tooth does not bounce forward by the force of the bow arm.

Han Fei drew two sets of gears, and then designed the teeth and crossbow mouth, and then thought about how to use the suspension knife to brake the crossbow mouth and release the strings.

Han Fei took a look at the disassembled Korean crossbow and the Korean crossbow.

Then I thought that as long as the crossbow mouth was designed in a semi-circular shape, the backward force of the suspension knife was used to brake the crossbow mouth to rotate and release the string.

In this way, the crossbow mouth designed by Han Fei replaced the role of the previous crossbow teeth, and with the crossbow teeth on the winding, this crossbow had two crossbow teeth.

Han Fei thought about it, this is all right, as long as the two crossbow teeth are reasonably designed and the division of labor is orderly, it can not only increase the power of the crossbow tool, but also increase the service life of the crossbow teeth.

As soon as he thought of this, Han Fei found that all the cardinal components of the crossbow must be applied to iron to ensure that the explosive force saved by pulling the teeth will not impact the crossbow body, and the original use of manpower to wind it, but the crossbow designed by Han Fei is different, it is to use the gear to push the winding crossbow teeth to the crossbow teeth that are directly braked by the suspension knife, so that the power of rotating the gear is only 30% of the strength of directly pulling the winding crossbow teeth, and it is not easy to hurt the hand.

However, due to South Korea's current forging technology, the range of the crossbow designed by Han Fei is estimated to be less than 500 steps, which is still inferior to the original 600 steps of the crossbow.

Looking at the scribbles on the paper, Lin Yuyan said to himself: "Let's call you [Divine Arm Crossbow]!" ”

Then, Lin Yuyan picked up the bronze ruler on the side and began to quantify the size of the design on the paper, after all, it involves gears and some more important things, and the size must be paid attention to, and there can be no too big error.

Immediately, Lin Yuyan recruited his subordinates and instructed him to take the drawings of the decomposition of the divine arm crossbow to Chen Kai and other craftsmen to build it, and then experiment separately.

……

Xinzheng City is coming.

On the other hand, in Zilanxuan at this time, several people were sitting in the room in the backyard, among which there were not only Wei Zhuang, Han Fei, Zhang Liang, and Zinu, but also two new faces.

Both of them were men, and one of them stood behind the other, holding his sword in both hands, and looked at the blue lake in the distance, and at the same time his eyes swept to other places, alert to the abnormal.

He is Gai Nie, who came out of the Ghost Valley together, and Wei Zhuang Shi went out of the same door.

And sitting on the ground, the man in the platinum and gold costume, the identity is self-evident, it is the king of the Qin State, in the future, the first emperor who is known as the first emperor of the ages.

Of course, today's Yingzheng, although he is the king of Qin, has little power and power under his control, and it is far less terrifying than in the future. Otherwise, why would he risk his life to come to this capital of South Korea on an adventure?

Ying Zheng and Han Fei are facing each other, Zhang Liang and Zi Nu are sitting on one side, and Wei Zhuang is the same as his senior brother Gai Nie, leaning on one side, holding his sword or looking at the sky, or turning his head to look at Bihu...

There was a faint sadness between his eyebrows, Ying Zheng's visit to South Korea this time was mainly because he had already heard of Han Fei's talent, and he attached great importance to his theory of ruling the country by law. Moreover, in Xianyang City, he felt the crisis even more, so he made a slight private visit, thinking that he would come to South Korea to see if he could get Han Fei's vassal.

However, after some conversation, he did see Han Fei's great talent, and Zhang Liang beside him also made Ying Zheng's eyes shine.

The sun moved slightly, and in the conversation, the day passed in a flash.

Ying Zheng looked at the sky through the window, got up and said to Han Fei: "It's getting late, I'll go back to the post station first, and I'll communicate with Mr. tomorrow." ”

Saying that, when Ying Zheng was still unsatisfied, it was obvious that he had benefited a lot from talking with Han Fei for a day.

Han Fei nodded, and also made a Korean gift: "It should be so, it's better for Shang Gongzi to go back early, Xinzheng is not peaceful at night now." ”

A simple goodbye, Ying Zheng refused Han Fei's send-off, and then went out of the backyard under the leadership of the purple girl, Gai Nie with a tense face, personal guard.

walked like this, and it didn't take long for the purple girl to hurriedly take Yingzheng back to the backyard, and Han Fei, Wei Zhuang and others, who had not left yet, were startled, and they all looked over and didn't know why?

Pulling the wooden door shut, the breath in the room was depressed, and under the gaze of many eyes, the purple girl said: "I can't go through the front door, somehow, now a group of guards are here." ”

As soon as these words came out, everyone was in an uproar.

Could it be against the King of Qin?

Han Fei thought so, but immediately shook his head, because the news of King Han's arrival in Xinzheng should be a secret and little known.

"I'll take a look." Han Fei let out a breath and said.
