Li Qieyou felt that after he came to the Tang Dynasty, he dared to bet on this sentence, which almost became his mantra.

But he can't blame him for this. Who makes Tang people gamble?

In addition, what he said is often questioned, so Li forget worry doesn't mind taking a bet to gain a little benefit for himself.

For example, he made armor with 100 steel, although he could force Yan Liben to take out 100 steel to make armor. But since Yan Liben doesn't believe his words, why don't you make a trivial bet with him that Yan Liben can willingly take out 100 steelmaking and make these 13 sets of armor for him?

Li forget worry will put forward such a bet, naturally have their confidence.

The iron armor forged by one hundred steelworks is stronger than he expected. The iron armor with a thickness of only about 1 mm can make Niu Wu's strong bow return in vain at a distance of 50 steps, which is enough to explain its firmness.

Second, Li forget worry has confidence in the compound protection concept of future bulletproof vests.

Although Datang could not produce Kevlar fiber for bulletproof vests of later generations, silk could play a similar role.

When Mongolian cavalry swept across Eurasia, their death squadron cavalry battalion, Balu camp, wrapped their bodies tightly with multiple layers of silk before each battle. It is wrapped in layers of tight and delicate silk and regarded as "soft armor" to reduce the damage caused by arrow feathers.

The world's first bulletproof vest was invented by a British tailor after the industrial revolution. It was made of coated silk.

Coupled with the leather lining, this hard, soft and tough three-layer armor is combined together. Li forgets to worry. He can still be shot through by Niu Wu's bow and arrow.

But Yan Liben and Niu Wu on one side would not see it that way.

Yan Liben carefully looked at the iron armor with a small hole shot by Niu Wu's strong bow. He thought that Niu Wu could shoot a hole when he was fifty steps away. If it was twenty or thirty steps away, could the iron armor not be pierced?

Even if the lining increases cowhide, what can it do?

The Tang army made thirteen armor, including leather armor.

The leather armor of Datang is made of multi-layer leather, mostly made of rhinoceros, shark and other leather. Leather armor is lighter and cheaper than metal armor. But for the defense of bow and arrow, the effect is not good.

The multi-layer leather can't stop the arrow feather. What silk and cowhide did your teacher say? What role can it play in the face of the arrow feather shot by the two stone strong bow?

As for the silk that Li forgets to worry about, what the hell is that?

Among the thirteen armours of Tang Dynasty, there was silk cloth armour.

The armor made of silk cloth has a beautiful appearance, but it has no defensive effect. It is only the usual clothes of military generals or the clothes used for guard of honor.

Therefore, Yan Liben naturally wouldn't think that the iron armor can resist bows and arrows by lining it with silk and cowhide. Isn't that a joke?

Although Yan Liben also admitted that the iron armor made with 100 steelmaking was indeed much harder than those pieces of armor made by the Tang army, Yan Liben felt distressed at the thought of using dozens of kilograms of 100 steelmaking to make a pair of armor.

Moreover, his teacher made these armor not to fight the enemy, but to be a "costume". He was naturally reluctant to give up such extravagant behavior.

It would certainly be a good thing if we could take the opportunity of betting with our teachers to save this batch of hundred steelmaking.

Thinking of this, Yan Liben nodded without hesitation and said, "OK, this bet is that the disciple has a fight with the teacher. The teacher has to keep his word!"

Niu Wu shook his head and felt that his husband was too confident. He bet with Yan Liben for fear of losing.

Li forgot to worry and said with a smile, "you are sure to lose. Be ready to make armor for your teacher."

Yan Liben didn't answer, so he immediately ordered someone to recruit the craftsman and began to transform the iron armor according to what Li forgets.

The extremely thin silk was tightly stacked on the back of the armor layer by layer by the craftsman. A layer of Tung paint was painted between each layer of silk according to Li forgetful's instructions.

After that, we found hard cowhide, wrapped it with silk, and riveted the cowhide and iron armor together with rivets.

The thickness of the reconstructed armor has increased a lot. But neither Niu Wu nor Yan Liben thought it would bring any trouble.

"Sir, the armor is ready as you ordered. Let's try it now?" Yan Liben can't wait. He can let his little teacher eat it once, but he's happy to see it.

Li forgot to worry about his eyes and planned to insure his bet.

"OK, libben, you let someone find a pig."

"Pig?" Yan Liben didn't understand what Li forgot.

Li forgot to worry and nodded naturally: "tie this iron armor to the pig. If Niu Wu's arrow can shoot through the iron armor and kill the pig, it will naturally be regarded as the teacher's loss. If it can't kill, hey hey, Li Ben, you can go and make armor for the teacher."

His ghost idea is to use the pig skin and thick fat layer on the pig to add a little trouble to the arrow feather.

Li Qieyou believes that even if the arrow feather shot by Niu Wu can penetrate the obstacles of iron armor, silk and cow leather, it is impossible to have greater penetration through the obstacles of pig skin and fat layer.

Yan Liben opened his mouth when he heard the speech. He always felt that something was wrong, but he couldn't say anything to refute.

The role of armor is naturally to protect the safety of the armored man.

It seems that if you shoot an immortal pig with an arrow feather at a distance of 20 or 30 steps, you can really prove the super defense of iron armor... But it doesn't seem that you bet with your teacher?

"Sir, the bet you made with me seems to be just a bet on whether arrow feather can shoot through armor..." Yan Liben said depressed.

Li forgot to worry, but no matter how much, he said forcefully: "if the arrow feather can't shoot the armored pig, how can it be regarded as shooting through the iron armor? Li Ben, the armor is to protect the armored man. This is a very rigorous thing. Fraud is not allowed!"

Yan Liben was so familiar with his old face that he knew nothing wrong, but he did not know how to answer it. He could only bow to Li Wangyou and show that he had been taught.

Niu Wu is also stunned. His husband is really a little shameless. Isn't it clear that Yan Liben is honest to bully others?

How thick is the pigskin? How can people compare?

He and his brother Niu Yong often go hunting in the Qinling Mountains. They are usually reluctant to provoke wild boars in the mountains. A thing with rough skin and thick meat. Several arrow feathers pierce it. It can not kill, but also often arouse the ferocity of wild boars.

Although domestic pigs are not as difficult to provoke as wild boars, they are not easy to be shot by several feather arrows.

Niu Wu naturally won't expose his husband's careful thinking. He just looked at Yan Liben with sympathetic eyes and bet with his husband that he might lose again.

There are no pigs in the valley where Cuiwei palace is located.

Li forgets to worry about making a special trip to the Ministry of the house. He rode back to Dingzhou village and got back a fat pig of about 200 kg.

The poor fat pig, who was regarded as an arrow target, didn't know what had happened. He was led to the arrow target and tied up. The special iron armor was also tightly bound to the side of the fat pig by the craftsman.

Li forgot to worry and said with a smile, "OK, Niu Wu, shoot. You can aim at the point. Don't shake your hand and shoot outside the iron armor. Even if you shoot the pig, you won't count."

Niu Wu rolled his eyes silently and didn't bother to pay attention to Li forgetful's ridicule.

He can accurately shoot the armor a hundred steps away, not to mention the distance of 20 or 30 steps, with his eyes closed.

Niu Wu simply drew an arrow with a bow and shot it out
