Li forgot his worries and was so angry that Li Er rolled his eyes and regretted.

He felt that he was also dizzy. How could he come up with that bad idea to give his love foal SA Luzi to him.

Now Li forget worry really shot the boar, and immediately let Li Er and a group of national leaders sit in the wax.

Li Er wanted to repent, but he couldn't pull down his old face. He could only say vaguely, "what are you panicking about? Can I still keep my word?"

Li forgets to worry, glances at his mouth and whispers, "who makes it clear? I just wanted to come here. I agreed to fight the prey, but I had to hunt wild boars instead. Isn't this bullying an honest man?"

Although he said this in a low voice, Li two listened very clearly. He could not help but get a long face and a dry cough.

"Cough, Ziyou, stop fooling around and quickly show me how you wind this crossbow?"

Li forgets his worries and is helpless. He can't force Li Er to ask for horses. He can only reluctantly pick up the composite crossbow in his hand, open a folding mechanism under the crossbow body, and hook the hook on it to the crossbow string.

After that, Li Qieyou pressed down the folding mechanism. Under the action of lever, the crossbow string was pulled back until the crossbow machine was hung to complete the string tensioning process.

This operation stunned Li Er, Cheng Yaojin and others, as well as the dandies.

"This... What's the reason? Why can you string the crossbow so easily?" Chumo asked.

Fang Yiai shouted with exaggeration: "this small iron bar can stretch the strings of a strong crossbow when pressed? How is this possible? Ziyou, you have applied immortal magic to the crossbow?"

Li forgets to worry about nothing and turns a blind eye. Isn't it a chicken talking with a duck to explain what the lever principle is with this group of "illiterates"?

Li Er's eyes flashed, pondered and asked, "Ziyou, the mechanism used to open strings on your crossbow is very like a suspender. You can enlarge the manpower. I'm right?"

The suspender is a hoisting machine made by using the lever principle in ancient China.

Li forgot to worry. Unexpectedly, Li Er could only look at the auxiliary stringer of the composite crossbow and associate it with the suspender.

Although Li Er couldn't say the lever principle, it also made Li forget his worries and admire it.

"My uncle is really wise. That's right. I just thought of making this mechanism by using the principle of the suspender to help the crossbow string. My nephew calls it an auxiliary stringing device."

Li Er nodded, took the crossbow in Li forgetful's hand again, looked at it carefully, shook his head and sighed, "this mechanism is very exquisite. Unfortunately, I think it's too fine, and it's still made of 100 steel. It's difficult to popularize it in the army."

Li forgot his worries and must admit that Li Er's vision was really original. Yan Liben had already lamented this problem at the beginning.

Although the auxiliary stringer is useful, it is not easy to build and the cost is very high. If we want to equip the army on a large scale, even if the national strength of the Tang Dynasty is becoming more and more prosperous, we can't afford it.

There is no solution to this problem.

After all, the auxiliary stringer requires high strength to pry the crossbow string with a tension of hundreds of kilograms. Only when it is made of 100 steel can the crossbow string be pulled without distortion.

"Your Majesty, the bravery of Tang soldiers is unparalleled in the world. What does it matter if they don't use such a powerful crossbow?" Cheng Yaojin shouted unconvinced. Yuchi Jingde and others nodded one after another.

The strength of the Tang army lies in its powerful iron cavalry and its bows and arrows.

These big men in the army of the Tang Dynasty don't like crossbows. Compared with convenient bows, they are more conducive to attack, and crossbows are better at defense.

At the beginning of the Tang Dynasty, these famous generals were full of thoughts about how to travel thousands of miles to open up territory for the country and kill enemy chieftains. Naturally, they were not interested in crossbows.

Li Er also knew the virtues of his generals. He just sighed and said nothing more. At least he continued to play with Li forgetful's composite crossbow.

Li Er glanced at the sight on the crossbow and recognized that it was just a special telescope. He was a little surprised that the telescope could be combined with the crossbow like this.

No wonder Li forgot to worry about being able to accurately kill wild boars from 300 steps away.

He immediately thought that it would also be useful to order people to build a batch of such crossbows and train them to kill each other's managers when the two armies face each other.

Li Er kept the matter in his mind and planned to order Yan Liben to make a batch of crossbows first.

Li forgets worry. If he knows what Li Er thinks, he will be surprised.

Isn't this the sniper of future generations?

If Li Er had trained these "snipers", I'm afraid Tang Jun's soldiers would be invincible.

But these are later words, not for the time being.

After playing with the compound crossbow of Li forgetful worry, they continued to hunt in the Forbidden Garden.

Li's first hunting trip was fruitful.

A wild boar weighing more than 200 kg, several pheasants, several rabbits and an elk were dragged back by Niu Wu and a series of episodes.

After leaving the Forbidden Garden, Li forgot to worry and did not return to the residence of Kaihua square in Chang'an city. Instead, he went straight through the city and returned to Dingzhou village.

He is now thinking about how to use rabies to kill yuan gaisuwen.

In fact, there are many ways to make yuangai Suwen die quietly, but Li forget worry is not a killer in future generations, but just an ordinary white-collar worker. It is difficult for him to think of the way to "kill" with rabies.

And even if he thought of using rabies, how to implement it is also a difficult problem.

It's easy to find sick dogs, but it's not easy to let those sick dogs bite yuangai Suwen.

Seeing that the goods could block the arrow plumes shot by Chumo on the same day, we know that yuangai Suwen has high martial arts.

Moreover, as Koguryo's deputy envoy, he is accompanied by guards. Where are those mad dogs so easy to bite him?

Moreover, even if yuangai Suwen is bitten by a dog, he may not necessarily be infected with rabies virus.

If we don't solve this problem, how can we kill the goods?

Li Qieyou has no good way to do this, but he doesn't plan to go back to discuss with her boss.

This attempt to murder others, even if Li forgets worry that he has done nothing wrong, he doesn't want the beauty boss to know.

Back at Bo's house in Dingzhou village, Li forgot to worry about going to the hot spring to relieve his fatigue. When Li Heng, the old housekeeper, came in and told him, "Lang, the government of Dingyuan County ordered someone to send two Kunlun Slaves, saying that he thanked Lang for his return gift of armor."

"Kunlun Slaves?" Li forgot to worry and was stunned. Then he remembered that when Li Er and a group of national leaders scrambled to send things to themselves in the Forbidden Garden today, Zhang Gongjin, Duke of Dingyuan County, seemed to say that he wanted to give himself two Kunlun Slaves.

At that time, there were too many people who wanted to give gifts. They didn't pay much attention to it. They just thought that Li Er's saluzi had gone.

Now Zhang Gongjin really brought the Kunlun slave to Li, but Li forgot his worries and began to feel a little tired in his heart
