Chapter 769

Niu Wu was very happy with his husband's orders. He hurriedly took down the holy clothes box behind him, took out the crossbow arm and string, and began to assemble.

Niu Wu and a group of Li Fu's trilogy naturally see what has just happened.

In Niu Wu's opinion, it was a saint and a group of princes who rushed to send something to his husband, which almost made him laugh.

Li forgets to worry about the crossbow that someone ordered to make. Others don't know, but Niu Wu and a series know it. Not to mention that it is used to hunt several prey, it can be said that it can be caught easily. In the face of heavy Armored Cavalry, this crossbow is a super big killing tool.

In order to make a composite crossbow, Li forgot to worry, but he didn't spend less time.

From the spring steel needed for the crossbow arm to the eccentric wheel and the lever winding device are difficult problems for Tang craftsmen to solve.

Fortunately, with the help of Yan Liben and a large amount of gold as a reward, the craftsmen were so excited that their eyes turned red. After trying hard day and night, they finally built the composite crossbow Li forgot to worry about.

If the cost is calculated, Li forgot to worry about throwing in at least two or three hundred liang of gold, equivalent to RMB 67 million in future generations, which is not expensive.

But as mentioned before, rich, willful, spend hundreds of taels of gold to make a "toy" out, Li forgets worry and doesn't feel heartache at all.

In later generations, he was a loser white-collar worker with millions of housing loans. He needed to calculate a full discount when ordering takeout.

Such arbitrary spending has always existed only in dreams.

But if he converted the gold and copper money in his current house into RMB, I'm afraid he could barely be a local tyrant.

After all, the gold cheated from the aristocratic family together with Li Er was worth at least 300 million yuan.

In this case, Li forget worry naturally spends money at will, only depending on whether he is in a good mood.

After weighing the composite crossbow with spring steel as the crossbow arm, Yan Liben was stunned to find that the tension force of the crossbow reached an amazing four stones.

This is equivalent to the string force of the Tang army's siege crossbow. Yan Liben really can't imagine how fierce the arrows fired by the crossbow will be.

At least he can be sure that at a distance of 50 steps, the 100 steel armor that can't be pierced by two stone strong bow will be easily pierced by this crossbow.

The powerful crossbow of four stones, even with the eccentric wheel, did not reach the level that Li forgets to worry about and can easily open the crossbow string.

Yan Liben was amazed at the eccentric wheel on the crossbow arm. After the eccentric wheel is used on the four stone strong crossbow, the string can be opened with less than the force of two stones.

But obviously, even so, this composite crossbow is still unable to use. In this way, the only way is to install a stringer using the lever principle on the crossbow.

After several experiments, Yan Liben finally worked with the craftsmen to overcome these problems one by one and complete the epoch-making powerful crossbow.

After getting the composite crossbow, Li Qieyou has been practicing in his residence for two days. He is very satisfied with the power and accuracy of the crossbow.

Originally, in Niu Wu's opinion, the crossbow made by Li forgetful was just a big toy.

A marksman like him disdains crossbows. After all, compared with the strong bow, the firing speed of the crossbow is too slow and the range is close.

However, when Li forgot to worry about getting the crossbow and shooting it several times, the power and accuracy of the crossbow surprised Niu Wu and a group of Li's family.

A special crossbow is made of refined steel. It is only one-third the length of an ordinary arrow feather.

After being shot by the composite crossbow, the crossbow easily penetrated the Tang army's iron armor from 200 steps away.

As for the accuracy, with the help of the sight, Li Qieyou can easily hit the center of the target with a crossbow from 200 steps away.

At this distance, even Niu Wu can't guarantee that he can shoot.

With such a powerful weapon in hand, it's no different from playing with a few prey.

Niu Wu and Li Fu's trilogy naturally snickered. They even sympathized with the saints, the national leaders and the dandies of Chumo. This time, they were cheated by their own husband disguised as a pig and ate a tiger.

The assembled composite crossbow surprised Li Er, Cheng Yaojin and others. The crossbow arm and string seem to be metal?

"Niu Wu, show me the crossbow." Li Er said.

Niu Wu naturally did not dare to neglect and respectfully presented the composite crossbow with both hands.

Li Er stretched out his hand to take it, looked at it carefully, and then confirmed that he was really right. The shape of the crossbow in my hand is strange, but if the crossbow arm is really made of metal, even the crossbow string is steel rope.

Cheng Yaojin, Qin Qiong and others were surprised to see the composite crossbow.

"Hiss... Your majesty, Ziyou, the crossbow arm of this crossbow is made of refined steel? This refined steel can also be used to make crossbows? I've seen it for the first time." Li Jing, the Minister of the Ministry of war, also breathed coldly and uttered a voice of surprise.

Li Er's eyes flashed and looked at Li forgetful worry: "Ziyou, your crossbow and crossbow arm are made of refined steel? How long did it take to make them? How much string force does this crossbow have?"

Li forgot to worry and nodded: "uncle said exactly. The crossbow arms are made of spring steel. Well, it's very troublesome. It took my nephew seven or eight days to ask the craftsman who is the supervisor to make them for my nephew. Zhang Xianli has weighed them in a book, about four stones."

His words immediately made Li Er, Cheng Yaojin and others almost stare out. They stared at him dumbfounded and didn't know what to say.

Seven or eight days Kung Fu?

Four stone string force?

Isn't this nonsense?

Bow and crossbow, an ejection weapon, needs elastic bow arms to provide strong kinetic energy.

Generally speaking, both bows and crossbows need to use hard and elastic wood, supplemented by composite materials such as corners and ribs to enhance elasticity.

Bow making is not a simple thing. It not only has strict requirements on materials, but also the process is quite cumbersome.

There are detailed records in the book kaogong Ji. It is recorded that the bow stem is analyzed in winter, the horn is treated in spring, the tendon is treated in summer, the materials are closed in autumn, the bow arm is placed in the bow box in cold winter, and the appearance is repaired in severe winter.

It can only be used after the bowstring is installed in the spring of the next year and hidden for another year.

The above complicated process takes two to three years to make a good bow.

The process of making crossbow and bow is basically the same, and even the process is more cumbersome.

Because of this, what Li forgot to worry said stunned Li Er and all the leaders, and felt that he was simply joking internationally.

"Zhiniang thief, don't talk nonsense, come back. What's the matter with the crossbow?" Cheng Yaojin roared.

Li Qieyou shrugged his shoulders innocently. To tell you the truth, why doesn't anyone believe it?

Li Er tried to pull the crossbow string and found that it was really full of tension. He tried his best to hang the crossbow string on the crossbow machine.

The string force of this crossbow is equivalent to that of breaking a crossbow. It needs at least the force of two stones, which is not as exaggerated as Li Lianyou said.

Li Er naturally thought that Li forgot to worry about talking big, but even so, if the crossbow could be made of fine steel, it would be a great thing.
