Inside the Manna Hall.

Everyone looked at Qin Huaidao, their ears pricked up and their eyes filled with expectation.

Qin Huaidao looked at everyone and saw that they were all Li Er's confidants. He was not afraid of leaking secrets, so he organized his speech and said seriously: "Your Majesty, let's talk about the personnel first. There are five thousand in total, one person and two horses, including three thousand Turkic cavalry who are good at riding and shooting.

, Two Thousand Swordsmen and Shield Bearers, we must choose people who are good at riding horses and can withstand cold and frost."

"This configuration is not bad, but it is not easy to choose a sword and shield player who is good at riding and can withstand cold and frost. You may not be able to choose two thousand." Li Jing reminded.

Qin Huaidao wished he could bring two thousand Mo Dao troops, but it was impossible. The Tang Dynasty didn't have many troops. One thousand was a lion's mouth. Unexpectedly, he actually agreed and continued: "It doesn't matter if you are not good at riding, but you must resist.

Otherwise, you will freeze to death if you go up there. Secondly, you must prepare winter clothes. Ordinary winter clothes will not suffice and must be thickened. It is best to wear silk cotton clothes inside to keep warm, and wear thick winter clothes filled with wadding on the outside. Then there are battle armor, cowhide boots, and feet.

Wrap it in silk cotton."

After returning from the Qinling Mountains, Qin Huaidao finally realized the horror of not having warm clothes. There was no cotton in the Tang Dynasty, so cotton-padded clothes could not be made. The rich people wore clothes made of silk cotton, that is, silk, or wadding, which was old silk cotton.

They are refurbished, cleaned, and then used to make winter clothes. They are essentially silk products, which is what Qinjiazhuang wears.

"This is not difficult. The imperial court has ready-made ones. Five thousand sets are still available, but these alone are not enough. I, the North Leng, know this." Li Er reminded.

"If the court has enough winter clothes, each person can wear two sets of silk cotton clothes and trousers to keep warm." Qin Huaidao smiled bitterly and said, what can we do without cotton? The people are poor and cannot feed themselves. There is no surplus food to raise ducks and geese, otherwise they can harvest

Some wool is made into a down jacket, which can keep you warm even if it is simple.

If you can't keep warm, you can't go up. Li Er, a man who knows the military, understood the reason and nodded in agreement.

The troops are available, the clothes are available, and the rest is equipment. Qin Huaidao continued: "Your Majesty, I will design two things to ensure combat effectiveness. One is a horseshoe, which is made of iron bars and nailed to the horse's shoe, just like giving a horse shoe.

Wearing a pair of hard shoes, horseshoes not only protect the horseshoes, but also make the horseshoes grip the ground more firmly, which is beneficial for riding and driving. More importantly, you don’t have to worry about wearing out the horseshoes and wearing down the horses during long-distance raids.”

"What is a horseshoe?" Everyone looked at each other, having never heard of it.

Li Er was the emperor on horseback, and he knew the importance of war horses best. The Tang Dynasty was not short of horses, but the hoofs of countless war horses were worn out, and they could no longer go to the battlefield. If the horses' hoofs could be kept intact, their military value would be too great, and he suddenly became excited.

, looked at Li Jing.

Li Jing also knew the importance of horseshoes. If it could be solved, Datang's combat effectiveness could be doubled. He was no longer calm, and even his breathing became rapid. He stared at Qin Huaidao and asked: "Xiannephew, are you serious about this?"

"How dare you deceive your Majesty about such a big thing? You will know once you try it, just like wearing a pair of iron shoes, what will happen if it does not hinder walking?" Qin Huaidao said confidently.

"Then you dare to go anywhere and step on anything." Li Jing said with certainty. He instantly thought of the fearless scene of thousands of troops roaring past, and his blood boiled. He looked at Li Er and said excitedly: "Your Majesty,

If it is true as Huai Dao said, the Tang Dynasty would be able to have 100,000 more cavalry in a short time, and its combat power would be doubled, without fear of any challenge. This is a unique feat."

Of course Li Er knew it. He stared at Qin Huaidao and asked: "The horseshoes you mentioned really don't affect walking?"

"Your Majesty, if I have to talk about the impact, it is to make it easier for the war horses to walk. No matter whether it is thorns or rocks, it will not hurt or take effort." Qin Huaidao said seriously.

"Okay, if this thing really exists, I will remember your great contribution." Li Er said excitedly, making up his mind not to pursue it even if the Khitan came back from defeat. The merits and demerits would be equal to each other.

Qin Huaidao didn't know what Li Er was thinking, so he continued: "This thing is very easy to make and it doesn't cost much. Let Chen draw a picture, and the Ministry of Industry will soon make it into a real thing. You will know it at a glance."

"Don't be in a hurry. Let's go back to the Ministry of Industry and try it out in person. Tell us about your other tricks." Li Er interrupted, with a smile in his excited eyes. With this thing, the Tang Dynasty would have one hundred thousand more cavalry, or even more.

, I get excited just thinking about it.

"Back to Your Majesty, I know a repeating crossbow that can fire thirty arrows in a row." Qin Huaidao said solemnly.

"What, you know how to repeat the crossbow?" Li Er's expression changed, and his brows furrowed slightly. It was a deadly weapon on the battlefield, and even the imperial court didn't have it. Wouldn't it be terrible if there was any rebellious intention? No, go back and talk to Yu Zhang carefully, like this

Talents must win over the royal family, and this consort is a given.

Li Jing also changed his face. He thought it was enough to overestimate Qin Huaidao, but he didn't expect it was not enough. Fortunately, this guy was willing to take it out, otherwise the court would not tolerate it. He quickly asked: "I know that Zhuge's Liannu fired ten shots at a time and was later improved by Ma Jun."

, making it a fifty-arrow repeating crossbow with greater power, but because the production was complicated and the arrows used had to be specially made, it was not mass-produced and was later lost. Can your thirty-arrow repeating crossbow be the same?"

Qin Huaidao had never seen Ma Jun's improved repeating crossbow, but he knew that Zhuge's repeating crossbow was made for fun with his comrades when he was in the army. Later, it was improved into a thirty-arrow continuous crossbow, so he said: "I don't know if it is the same, this junior.

Originated from the "Secret Code of Observation of Things" written by pre-Qin warlocks."

Anyway, just push things that cannot be explained to the caves of pre-Qin warlocks.

"Let's go to the Ministry of Industry. This thing is too special and cannot be leaked." Li Er looked at Qin Huai and said.

Of course Qin Huaidao understood that if it were not for this war, he would never take it out, and quickly agreed: "Don't worry, Your Majesty, I swear on my father's honor that I will never leak it."

The ancients valued trust and promises, and filial piety was the first priority. Swearing by one's ancestors is definitely a serious oath.

Li Er smiled with satisfaction: "A horseshoe and a thirty-bolt crossbow, each of them is of great significance. The contribution lies in the country. Don't worry, I will not be stingy with rewards."

Can things from later generations not be of great significance?

Qin Huaidao thought that he would send it out anyway, so he might as well give it away thoroughly and said: "Your Majesty, this crossbow has not been named yet, why not call it Zhenguan Crossbow, it sounds domineering."

"The thing is yours, how can I have this reputation?" Li Er smiled with satisfaction.

Li Jing smiled knowingly and said: "Your Majesty, this is a good name. If the child has a heart, why not let him fulfill it."

"I second my opinion, the Zhenguan crossbow sounds loud!" Fang Xuanling said with a smile.

Changsun Wuji also said: "I also think the name Zhenguan Nu is good. Master Qin's crossbow is a tribute to the country. After all, it is the saint who is wise and brave and has a keen eye for jade. He discovered Master Qin's thousand-mile horse and entrusted him with an important task. Now Qin

Your Majesty's return to the Holy One will surely become a good story, not to mention that Mr. Qin will soon be the Holy One's perfect son-in-law. A son-in-law should be filial to his elders, how can the elders bear to refuse?"

"Hahaha!"

Li Er became more and more satisfied. He had no objection or approval, but no one was a fool.

Qin Huaidao looked at Changsun Wuji. In terms of flattery skills, the important ministers around Li Er were really unmatched, so he didn't say anything.

The group left in a hurry and went straight to the Ministry of Industry.

Duan Lun, the minister of the Ministry of Industry, and several officials from the Ministry of Industry were waiting at the door. After some greetings, Li Er said: "Duan Aiqing, Qin Fuyin is coming to do something. Please make arrangements."

"According to the order." Duan Lun agreed and looked at Qin Huaidao: "I wonder what Mr. Qin wants to do?"

"I've met Mr. Duan." Qin Huaidao said politely and added: "Some important items must be kept strictly confidential. Xiaguan will give you the drawings. I also asked Mr. Duan to make a sample to try first, if you can."

"No problem, where are the drawings?" Duan Lun agreed.

"If you need to paint now, please ask Mr. Duan to provide convenience."

"This is simple. Please move here, Your Majesty." Duan Lun looked at Li Er and saw Li Er nodding, so he led the way to his office. He asked Li Er to take the chief seat, and then settled in the other few seats.

The minister sat down, made tea for himself, and said: "Qin Fu Yin, the pen, ink, paper and inkstone are all on the desk, please help yourself."

"Thank you very much." Qin Huaidao came to the desk, spread out the paper, and picked up the brush. He didn't feel very good. He took a piece of charcoal on the brazier, broke it apart, and sharpened it. It became much easier to use it in three or two strokes.

Draw the horseshoe, mark the dimensions, and then draw the pattern of the repeating crossbow.

Not long after, a pattern of a repeating crossbow appeared on the paper. It was a three-dimensional rendering, and even the shadows were drawn. It was extremely lifelike. One look at the method showed crossbow arrows flying out, which was inexplicably chilling. Qin Huaidao did not stop and drew each component separately.

, mark the dimensions, and then draw the crossbow arrows, noting the key points and precautions for making.

After all the drawings were finished, Qin Huaidao clapped his hands and smiled with satisfaction as he looked at the drawings. He had not lost his craftsmanship.

"This painting is so lifelike, just like the real thing, it's incredible, even the painting saints are just like that." A voice sounded, it was Duan Lun who came over out of curiosity.

"Master Duan, this is a blueprint." Qin Huaidao corrected.

"Don't make any noise, let me enjoy it." Duan Lun interrupted.

After hearing the news, Li Er and others gathered around and were amazed when they saw the drawing. Fang Xuanling said: "I have never seen this kind of painting before, as if it came out of paper."

"Realistic and vivid, this is a brand new painting method." Changsun Wuji also praised.

Everyone is used to seeing two-dimensional paintings, but this is the first time to see this kind of three-dimensional painting, and it feels very novel.

Qin Huaidao reminded: "You should pay attention to the drawing itself, this is not a painting."

"drawing?"

Everyone was startled, and then realized that this was a drawing, not a painting, but they could only understand it roughly. They all looked at Duan Lun, and Li Er couldn't wait to ask: "Duan Aiqing, can you build it?"

"Going back to your Majesty, the size marks on it are clear, as well as the key points and precautions for forging. I have never seen such detailed and realistic drawings. They are just like paintings. If you still can't make them, I have no shame to stay in the Ministry of Industry. Please ask me

Your Majesty, please wait for a moment while I go make arrangements." Duan Lun said quickly.

"Remember to keep it secret. Once it is leaked, the nine tribes will be punished." Li Er warned.

Duan Lun was startled, and then realized that the drawing was not simple, and solemnly agreed: "I know what to do, please rest assured, Your Majesty."

"Go ahead, make the horseshoe first and let me take a look." Li Er waved his hand and returned to his original position to sit down.

Everyone gathered around and sat down again.

Qin Huaidao also came over. Li Er looked at Qin Huaidao with satisfaction: "I didn't expect that your painting skills are so good. Can you draw a portrait for me?"

"No problem, is there a reward?" Qin Huaidao agreed.

"You want a reward for painting my portrait? If you don't get the chance from others, hurry up and paint it." Li Er cursed angrily, who knows that he wants a reward every day.

Qin Huaidao was not happy and said: "Your Majesty, there is no reason why you should not be paid for work. You should pay some amount. It is just your intention. Let the humble ministers work in vain. If it spreads, it will damage the saint's benevolence."

"Let's talk about it after we finish painting."

"okay!"

Qin Huaidao returned to the desk and picked up a piece of rice paper. After thinking for a while, he changed it to a smaller one. Thinking that Li Er turned around and wanted to draw a larger one, he had to give up some blood. He was too stingy, so he spread out the rice paper.

Press it down and grind the charcoal into three types: coarse, medium and fine. Instruct Li Er to sit up straight and start drawing.

Everyone came up to watch curiously, and saw Qin Huaidao sketching out the outline in a few strokes, and then painted the eyes, slowly and carefully. Gradually, a pair of bright eyes appeared on the paper, as if they had spiritual energy.
