The sun has long been hanging above Xianyang City, Xianyang Street is full of people, a car came to the gate of the palace, two people got down from the car, one is the inner servant Zhao Gao, and the other is an old man in a plain robe, although he is old, his body is very strong.

"Master Lu, please ......," Zhao Gao said respectfully to the old man.

"Zhao Nei, please ......," Master Lu said.

In a moment, the two of them had already arrived at the study of Yingzheng Xianyang Palace.

Zhao Gao said respectfully outside the study: "Your Majesty, Master Lu Banlu, please come." ”

Hearing the sound outside the door, Ying Zhengyi, who was still reading a book, put down the bamboo slip and said, "Please." ”

Lu Banna is known as the existence of the carpenter's grandfather, although the public loser's mechanism is domineering, it is basically used for war. But it doesn't mean that Lu Ban himself is a hegemon or a war maniac. Many of his inventions were in the service of life, such as drills, planers, shovels, curved rulers, ink fountains for marking lines, and so on.

Zhao Gao led Lu Ban into the study, and the two of them saluted Ying Zheng.

Ying Zheng said: "Master Lu is polite, today Gu invited Master to come to discuss something, so there is no need to talk about the relationship between Master Lu and the Mo family." ”

Hearing this, Lu Ban was a little displeased, his face fell, his grievances with the Mo family were well known, and Ying Zheng mentioned the Mo family, wasn't he slapping him in the face in the face. Said coldly: "What is the king's important matter, please say quickly?"

Ying Zheng was not angry when he saw Lu Ban like this, if he hadn't been afraid of being a king, he would have turned his face long ago.

Ying Zheng said with a smile: "Master Lu is not in a hurry, the Mo family thinks that Master Lu's mechanism technique can only be used in war, and Lone's understanding is that Master Lu should want to use his own mechanism to quickly help a country dominate the world, so as to end the war, although it will cause some killing, but in order to have no more wars in the future, it is all worth it." The Mo family's thought is recognized by Lone, but the practice, Lone does not approve, stopping the war is only temporary, and the killing caused by ten or a hundred years later is more, compared with Master Lu, Lone thinks that the Mo family has fallen behind. ”

Hearing Ying Zheng's words, Lu Ban really thought that he had met his bosom friend, and after so many years, someone could finally understand him.

What did he lead the losers to join the Qin State, he was rich and rich, he Luban did not lack these, in order to help the Qin State dominate the world and prove himself, this is what he wanted.

The corners of Ying Zheng's mouth hooked up a smile and continued: "Lone wants to give Master Lu a suggestion, Master Lu's mechanism technique is unparalleled in the world, I don't know if Master Lu has ever thought of using mechanism skills to benefit the people." Doesn't the Mo family advocate mutual love? Their Mo family has such a powerful trick, and how many of them are for the benefit of the people, if Master Lu can use the trick to invent a trick for the benefit of the people, he will definitely be able to crush the Mo family. ”

Lu Ban looked at Ying Zheng with glowing eyes and said: "Since the king proposed this law, there must be a draft in his heart, and please come." ”

Ying Zheng said lightly: "Master Lu should know that the ox pulls the plow, has the master ever thought of replacing the ox with some kind of mechanism, turning a plow into five... Heptad... Ten of them, so how much land can be cultivated in a day for the people?"

Lu Ban said excitedly: "This law is a second, a second, why didn't I think of it." ”

"Your Majesty, Lu Ban wants to go back and carefully study the kind of mechanism technique that the king said, there is a lot to be done. Lu Ban said with great interest.

"Master Lu, please slow down, I still have something to discuss with the master. ”

Ying Zheng sighed secretly, really like those scientists in the 21st century, as long as there are new discoveries in their research, they will definitely be eager to study without sleep and food.

"I wonder if the king has anything else to discuss with Ban?"

Lu Ban said with a hint of unpleasure, his love for tricks is like a table full of delicacies in front of him, you can taste it with chopsticks, but he was suddenly interrupted, who can be happy.

Ying Zheng said: "What does the master think of steel?"

Hearing Yingzheng's words, Lu Ban's eager heart also calmed down, thought for a while and said: "Iron is hard and brittle, and steel is harder and tougher than iron. I wonder what the king means?"

Ying Zheng said: "The use of steel and its benefits are known to the seven countries, but why is it still dominated by bronze, because the output is too small, it can't support too many uses, and countries can only use iron on the tips of weapons." ”

Seeing Lu Ban's puzzled face, Ying Zheng continued: "There are many reasons for the low output: first, the smelting technology of steel is not very mature, second, the mining of ore is too difficult, and third, the smelting and tempering of ore require too much manpower and material resources. The Seven countries simply couldn't afford it, so they had very little steel in each country. ”

"Lone has an idea, Master Lu should be very interested. ”

Ying Zheng said that these Lu Ban also knew that he Lu Ban was a machine man, and many of the materials of the mechanism were wood, and he also thought about using iron to make the machine material, but he gave up later, the reason is that iron is in the hands of various countries, and there is too little iron.

He had some guesses in his heart when he heard Yingzheng's words, so he asked tentatively: "Is there any way for the king to increase the production of iron?"

Ying Zheng smiled and said, "There is no Lone, but Master Lu has." ”

Lu Ban smiled: "If Ban has a way, why wait until today." ”

Ying Zheng said lightly: "Lone just said, first, mining requires too much manpower, and there is still very little iron ore mined every day, and second, steel forging is time-consuming and laborious. The only one who can solve this problem is Master Lu. ”

Ying Zheng once again said that he could solve this problem, Lu Ban was a little puzzled, and suddenly he remembered the ox plow that Ying Zheng talked to him about earlier, and everything understood.

"Tricks. Lu Bandao.

Ying Zheng replied: "Yes, the trick, one, in terms of mine transportation, you can lay two tracks, and then design an object shaped like an opening above the box, and install four wheels with grooves at the bottom, and then fix the wheels on the track, this thing is called a minecart." A rope is tied to one end of the minecart, and the other end of the rope is tied to a pulley outside the mine. The pulley can be pulled out by rotating the pulley, and the power of the pulley does not need to be pulled by people, and it needs the assistance of Master Lu's tricks. In terms of mining, Master Lu can create a trap to speed up mining. Second, the tempering of steel requires Master Lu to use the technique to create some kind of mechanism instead of manpower. ”

Lu Ban's eyes lit up, and he said happily: "These ideas can basically be done, and the king is really a genius." ”

Ying Zheng just smiled, these are common in later generations, and they are not worthy of pride. Lu Ban and others are also limited by the times, and there are also organs that are not well recognized, and all the sons and hundreds of schools are actually promoting their own ideas, and there are a few people who really consider the people.

"Master Lu is willing to serve in the Inner Mansion, and the Inner Mansion will never interfere with the master's work, everything is up to the master's will. The inner house can provide better conditions for the masters. ”

The Inner Mansion was an important institution for the manufacture of weapons in the Qin State, and was in charge of all matters by the Inner Decree, the highest governor of the Inner Prefecture. There is also an army that guards and patrols day and night, and no one can enter without a passcode.

Lu Ban was a little moved, thought for a moment and said, "Ban, thank you, the king." ”

Ying Zhengxi said: "Master Lu's ability, no one in the world knows who doesn't know, and it is the luck of my Qin State that the master can enter the inner mansion." ”

Hearing Yingzheng praise him like this, Lu Ban was also very happy, after all, although he Lu Ban was very skilled, he was still a cheap job in the eyes of some nobles, and it was a good thing for him to be valued by the king of a country.

Lu Ban said with a smile: "I, Lu Ban, have lived for more than ten years, and I have studied countless techniques, but I have never thought about using it for the people, the king is only nine years old, and he loves the people so much, Ban's original choice is really not wrong." ”

After speaking, he said goodbye and left, and the rickety figure stretched longer and longer under the oblique rays of the sun, and how many people knew that the person's heart also contained the dawn people.

The mechanism of this world is very developed, but many of them are used for war or other face-to-face, Ying Zheng wants to introduce the mechanism technology into the civilian use, and truly benefit the people.

Ying Zheng came from later generations, and clearly understood that if the people of Qin wanted to live a good life, they must liberate the productive forces, and when he found that the mechanism was more developed than he originally imagined, he germinated the idea of replacing labor with machine technology.

After his careful investigation, there is a great possibility of success, and if he can really succeed, the people's lives will be greatly improved, and as for other aspects, he can only take it step by step.

"The Three Treasures of the Horseshoe and the Saddle have been created by the people in the inner house, I wonder if the king has gone to take a look?" Zheng He reported when he entered the palace.

Ying Zhengxi said: "Zhao Gao, send someone to invite Wu Anjun Bai Qi and General Meng Fu to come to the palace racecourse. ”

"No"

After Ying Zheng finished speaking, he and Zheng He went to the racecourse.

Horseshoes and saddles are two indispensable things for cavalry, Qin has 100,000 cavalry, as long as 100,000 horses are equipped with horseshoe and saddle, the combat effectiveness of 100,000 cavalry will have a very terrifying increase.

At tea time, Bai Qi and Meng Fu hurriedly arrived at the palace horse farm, and saw Ying Zheng and Zheng He staring at a zong-colored horse, and there were some things draped on the horse's back. It is surprising that a soldier of the Praetorian Guard rode wildly on horseback, with a bow and arrows in his hand, and the horse was about a hundred feet away from the target, and the soldier stood up as if he were walking on the ground without jolting.

With a "whoosh" sound, it hit the bull's-eye.

As a veteran in the army, of course they understand how difficult it is to hit the bull's-eye at a distance of 100 zhang, and how can they not be shocked when it happens in front of their eyes. At the same time, with their eyesight, they could see that what was draped on the horse's back played a great role.

"Two generals, the king is waiting for the two. Zhao Gao's voice sounded in the ears of the two.

The two of them retracted their gaze and walked towards Yingzheng with an uncalm heart.

After a salute, Bai Qi couldn't help but ask, "Your Majesty, I don't know what the brown horse is wearing on the quilt?"

Ying Zheng smiled: "Saddle, General Bai will try it when you go up." ”

Bai Qi saluted, and under the guidance of the soldier who had just shot the arrow, he stepped on the horse, jumped up, stepped on the stirrups with both feet, and held the reins of the horse with his left hand.

"Driving...... ...... driving"

Bai Qi urged the horse to run in the open field, back and forth a few laps feel unpleasant, both feet stepped on the stirrups, the crotch did not need to clamp the horse's back to feel very stable.

After a few laps and several difficult maneuvers on the horse, I got back to the starting point.

"Lil...... Lil ......"

got off the horse, returned to Yingzheng's side and said happily: "Your Majesty, if my Great Qin cavalry war horse is equipped with this saddle, it will be a great help to the soldiers and soldiers." ”

Although Meng Fu didn't go up to ride and try it, he also saw Bai Qi's movements. Hearing Bai Qiyi's words, he also agreed: "I also ask the king to order the inner government to make saddles for the 100,000 cavalry of Great Qin." ”

Ying Zheng said: "Two Aiqing, please see, this iron is called a horseshoe." The horse's hooves are in contact with the ground, and they will fall off quickly due to the friction of the ground and the corrosion of the water. The horseshoe not only protects the horse's hooves, but also makes the horse's hooves more advantageous for riding and driving. ”

After listening to Ying Zheng's introduction, Meng Fu said: "Most of my Great Qin cavalry are archers, and now with saddles and horseshoes, cavalry can be equipped with weapons such as spears and swords. ”

The superiority of the cavalry was well known to the two, fast and mobile. It turned out that because the soldiers were all collapsed on the backs of bare horses, when the horses were running, after being slid forward by bumps, the soldiers had to be distracted and clamp the horse's back with their legs to prevent falling, so most of the 100,000 cavalry were archers.

As soon as the saddle comes out, not only will it not slip forward and backward, but it also frees the soldier's feet, and he can also stand and hold a weapon on the stirrup, and use his strength to fight the enemy.

Bai Qi said: "From now on, my Great Qin cavalry will be a terrifying existence, and it will definitely become a nightmare for the enemy." ”

Ying Zheng and Meng Wei both nodded in agreement, and Ying Zheng knew better how terrifying a cavalry with a saddle and a horseshoe was.
