Although he didn't believe it, Wu Guli didn't make it difficult for the other party, he called a person to come: "Wang Lin, guard for me for a while, I will lead this Langjun into the valley."

Zhang Xiu thanked him, and Wu Guli hurriedly returned the salute: "How dare you be Lang Jun's gift, if Lang Jun is really good at arithmetic, he is the gentleman of the school, and when the time comes, he will give Lang Jun a disciple's gift." ”

"Huh?"

"My family Langjun said that we can also go to the class to learn some skills, and we can take charge of ourselves in the future." Bone power.

Zhang Xiu glanced at him in surprise, only to see this Kunlun slave blinking his cow-like eyes, moving forward and backward, his eyes full of longing.

Let the servants also learn arithmetic...... This Ye Langjun is really extraordinary. It's just that it is said that he is also proficient in arithmetic, why don't he teach domestic servants, but recruit another teacher

Zhang Xiu didn't know that Ye Chang didn't teach himself, but he really couldn't spare time.

He was at home, and he had a lot to do: planning, experimenting, writing stories, and dealing with relationships. He is not three-headed and six-armed, where can he take care of everything, so he needs a few gentlemen in general arithmetic to lay the foundation for his students.

In terms of time, the children and nephews of those rangers will be sent in about ten days, and the accommodation here has been arranged, so they can live in the village first, and then they can live in Wolong Valley after the school is ready.

After entering the valley, I saw the famous pavilion, and the Burrow Inscription on it had already spread throughout the Central Plains, and Zhang Xiu could memorize it. After passing this pavilion, Wu Guli led him to the right, but Zhang Xiu let out a "huh" and ran to the left.

"That's a waterwheel...... Wu Guli called out from behind: "Lang Jun, you can't go over there." ”

"A certain look at the waterwheel" Zhang Xiu was very stubborn.

He stood on the side of the watermill and looked at this thing made of many parts of wood and iron, and his heart moved.

Datang is not without waterwheels, but this waterwheel makes Zhang Xiu feel that there seems to be something wrong. Soon, he realized where something was wrong.

"Original...... In this way, Zhang Xiu's eyes flashed with a sudden realization, and at the same time, he floated with admiration: "Wu Guli, this waterwheel, but your family Langjun made it?" ”

"My family Langjun designed it and invited a famous craftsman to make it."

Wu Guli was a little sullen, and the person in front of him who claimed to be a candidate was a little rude, and he broke in without the consent of the master. But he can also say that it is sneaky, and it seems that he is really curious about this waterwheel.

Zhang Xiu clenched his fists and said with some excitement: "Sure enough, sure enough, I didn't expect it badly, after Uncle Liang and Duke Liang, the only one in the world who can guide me is Ye Langjun."

"Lang Jun, please come over here." Wu Guli persuaded.

I followed the black bone side and turned to the right side of the black bone, and after walking for a long time, I saw that a piece of slope was leveled, some places were being raised, and some places were flattened, and it looked like a piece of two acres in size was going to be cut. Dozens of small workers under the command of craftsmen are building houses, and the materials used, in addition to green bricks and red tiles, there is also cement, which is already common in Chang'an but is still very rare in other places.

Cement was invented by Ye Chang, and Ye Chang used it here, and Zhang Xiu was not strange. He didn't know that the cement was now a monopoly of the imperial court, and Wolong Valley could use this, or because the imperial court set up a cement kiln in Jiaozuo, and originally wanted Ye Chang to be the ambassador, although Ye Chang resigned, he still made a lot of suggestions for this cement kiln, including site selection and process design, and he played an important role. Now he wants to use cement, and it is not too difficult to buy some new ones from the cement kiln.

What intrigued Zhang Xiu was how the craftsmen on the roof were transporting baskets of bricks and cement.

Instead of carrying them by hand, they used a winch – a winch that used a pulley block that made it very easy for craftsmen to lift hundreds of pounds of things up the stairs.

Others may just be surprised, but Zhang Xiu is an expert, and when he saw this pulley set, he was surprised: "Could it be ...... Ye Langjun is a descendant of the Mo family? ”

When he had said that, he burst out laughing and shook his head: it was impossible.

The Mo family at the time of the Warring States Period had long been eliminated by history, and it was only among the craftsmen. Ye Chang, the name of the poem moves all over the world, how can it be a person from the Mo family?

Moreover, the people of the Mo family have always been frugal and self-controlled, and they are unwilling to exceed the rules, and the so-called conformists are also, I heard that this Ye Langjun is so luxurious and likes to have fun, where is there a little like the Mo family.

However, this discovery made Zhang Xiu look forward to meeting Ye Chang even more: perhaps only such a knowledgeable person can solve the countless puzzles in his heart.

"This is the school, my master with bamboo as the bones, masonry as the muscles, with cement and lime as the skin, after the completion, can accommodate more than ten gentlemen and more than 100 disciples." Seeing him stop, Wu Guli explained: "Don't see that I haven't seen it yet, my master said, after it is built, even the Guozi Temple will not be compared."

Zhang Xiu nodded, not thinking that Ye Chang was bragging.

Of course, there are no talents in Guozi Temple, but it is better than arithmetic, but I am afraid that those students are not as good as him Zhang Xiu. He has to come here to ask Ye Chang for teaching, those students ......

The black bone force led him to continue walking, and then he passed away, and it was Ye Chang's house.

Since Ye Chang started to build projects in Wolong Valley, he has hardly stopped. His house, after two expansions, is now beginning to take shape. However, because there was no cement at that time, his house was still built of traditional materials, and the walls were painted with lime on the outside, according to his preference.

From a distance, the courtyard wall, as white as snow, is hidden in a golden leaf, which is very refreshing and lovely.

Zhang Xiu couldn't help but take a breath, and there seemed to be the fragrance of those maple leaves on the tip of his nose.

There are many wild maple trees in Wolong Valley, Ye Chang pays attention to protection, these maple trees begin to turn yellow in autumn, and after a while, you can see the red leaves like fire.

However, Zhang Xiu then realized that the fragrance did not belong to the maple leaf, but the fragrance of osmanthus flowers.

Ye Chang moved a few laurel trees to his house, but he didn't expect them to bloom this year, the fragrance was fragrant, and there was only a faint one in the distance, but when he came closer, he was refreshed.

Just under the laurel tree, a shirtless monk, with his chest hair exposed, laughed and beat a group of teenagers with a stick. The group of teenagers were driven by him to run in all directions, but they could not get past the lime white circle on the ground, so they had to be beaten a few times in embarrassment.

Zhang Xiu was not interested in these, he just felt a little strange in his heart: with Ye Chang, the atmosphere of the villa should be very quiet, and this group of noisy monks and teenagers are really incompatible with the atmosphere here.

"Lang Jun is here, please wait here for a while, and wait for a certain person to go and say a word - the guest's surname is Zhang Xiu, can there ever be a word?"

"Zicai, giant deer man."

Zhang Xiu has no name, so he can only be named by Wu Guli. He saw the Kunlun slave trotting towards the courtyard wall, and came to one of the osmanthus trees, under which were sitting several men. Kunlun Nu saluted one of them with his back to this side, and the man turned his head in surprise, and Zhang Xiu couldn't help but be surprised when he saw it

It's familiar......

Ye Chang also felt that this person was very familiar, but he couldn't remember it for a while.

After he got up, Jia Mao'er and others next to him also followed, these rangers in Chang'an, of course, were not as good as Shi Shanzhi, so the monk gave up the training of those teenagers and followed over.

More than a dozen people came over at once, which made Zhang Xiu feel great pressure.

"The honored guest is the giant deer Zhang Gongzi, who came to apply for Mr. Arithmetic?" Ye Chang asked.

"It's Zhang Zicai down there." Zhang Xiu saluted: "Apply for Mr. Arithmetic - and ask Ye Langjun some questions." ”

"Questions?"

"Ye Langjun has ever seen a water transport armillary sphere?"

"Huh?" Ye Chang was stunned when he heard the "Water Transport Armillary Sphere", the name of this thing is also very familiar, it should be ...... It's an astronomical instrument.

Zhang Xiu didn't wait for him to respond, so he said to himself: "I look at the waterwheel made by Ye Langjun in the valley, and the magic of mechanical operation is quite similar to the water transportation armillary sphere. However, this kind of machinery has a big problem, that is, the iron tools at the joints are easy to be corroded by water, and then they can no longer be used. It is for this reason that the armillary sphere of water transport in the DPRK has to be included in the treasury ......"

He said to himself, as if he was immersed in his own world, Jia Mao'er frowned: This guy is so rude.

When Zhang Xiu said this, the topic changed, and he asked again: "Ye Langjun has ever received a suicide note from the Mo family?" ”

This question made Ye Chang even more unable to answer, he was stunned: "The Mo family's suicide note? ”

"Mo Zhai once said, 挈, powerful, powerless. What is not right is stopped at giving, and the rope is also restrained, and if it is pierced with an awl. The long and heavy ones are down, and the short ones are light

When he said this, Ye Chang suddenly felt dizzy, what kind of thing is "挈", how can this guy "��" come to "��" to "��" a lot of nonsense?

Ye Changtong's literary language, otherwise he would not be able to mix well in this era, but fluent literary language and good literary language are two different things, not to mention that the literary language quoted by Zhang Xiu is a big unpopularity. However, Zhang Xiu talked about this matter and talked endlessly, and after a while, he ended this quotation, and then said: "Where I watched the school, Ye Langjun taught craftsmen the technique of holding weight, and this text in the original ink scripture felt cheerful. The Book of Ink only has its text, but not its picture, presumably Ye Langjun got Mo Zhai's suicide note, so he can make this thing......"

"Wait a minute, wait a minute, I make a waterwheel, and that heavy thing, which is not the same as the water transportation armillary sphere and Mozi, but it is me...... I did it by summing up the experience of my predecessors. Ye Chang finally found an opportunity to interrupt this person.

"Really?" Zhang Xiu looked shocked.

"True"

"Sure enough...... Ye Langjun is really an uncle, Liang Gong's character"

Zhang Xiu talked to himself again, Ye Chang saw that he was immersed in his own world again, and he patted him on the shoulder, regardless of the rudeness: "Your Excellency said that you want to ask questions, are they not these questions?" ”

"Naturally not, there is a question, it was originally asked by someone in Chang'an City, why can the Kong Ming lantern rise into the air, and the fire will fall?"

As soon as this question came out, coupled with the talented "Liang Gong", Ye Chang patted his head and remembered this person.

This person is the guy he met on the street with Worm Niang on the day of the city competition. At that time, this guy was talking to himself, asking himself why Kong Ming Lantern could go to the sky, Ye Chang replied casually, but he had several questions one after another. The insect mother thought he was annoying, and pulled Ye Chang away, but she never thought that this guy had run hundreds of miles in order to pursue these problems, and chased Xiuwu to come.

"I've seen you in Chang'an," Ye Chang said.

Zhang Xiu looked Ye Chang up and down, and nodded: "I also think that Ye Langjun is familiar." ”

He doesn't have Ye Chang's memory of people, or in other words, he can't remember people at all, unless he is quite familiar with people.

"Don't ask me first, I have a question for you." Ye Chang was holding a folding fan in his hand, and he shook it: "You keep saying that Uncle Ling and Liang Gong, I don't know who these two are?" ”

"Uncle Dahui Zen Master, Liang Gong Lingzan, is a friend of Uncle Jia."

"Dahui Zen Master ......" Ye Chang has never heard of this name, presumably it is an unknown person in history, another Liang Lingzan, he is a little impressed, but not deep. After pondering for a while, he felt that these two people were not important people, so he said again: "You two elders, you are proficient in the way of machinery?" ”

"These two elders, the way of machinery, are unique in the world, but they are longer than the celestial calendar."

When he said this, Jia Mao'er next to him was not convinced.

These days, they live in Wolong Valley, on the one hand, they are temporarily idle, waiting for the several plans proposed by Ye Chang to mature, and on the other hand, they are also closer to each other's feelings. In order to make them more convinced, Ye Chang took them to visit several machines, so in the minds of Jia Maoer and others, Ye Chang is a figure on a par with the carpenter's grandfather Lu Ban

A guy who came out of nowhere, a monk and a man surnamed Liang, dared to call himself a mechanical man in front of Ye Chang

"That's Ye Langjun not out of the mountain, if Ye Langjun comes out of the mountain, they can't be considered alone, if they are not convinced, let them come to meet Ye Langjun's whimsy

"The two of them are already immortals, and they can't see Ye Langjun's miraculous skills. If they can see Ye Langjun's miraculous skills, they will feel like they are confidants......"

"Do you like arithmetic?" Seeing that this person was about to immerse himself in his own world, Ye Chang hurriedly asked a question: "If there is a certain problem, you may solve it?" ”

This person claimed to be here to apply for Mr. Arithmetic, although he also admitted that he was just saying it to see Ye Chang, but Ye Chang didn't have a suitable person in his hands anyway, and with the idea that being idle was also idle, he wanted to see if he was really successful.

In fact, Ye Chang doesn't have much hope for this person, it can be seen that even if this person is proficient in arithmetic, he is not good at teaching, he may be a research-oriented talent, but he is not a professor-type talent.

"If you can solve it, Ye Langjun is willing to solve a puzzle."

"Know everything, you listen to the question." Ye Chang came up with a problem of chickens and rabbits in the same cage, this topic is not too difficult, but if it is just an ordinary person, it is not possible to solve it

Jia Mao'er next to him waited to start counting with his fingers, but Zhang Xiu just hesitated for a moment, and then reported the correct answer.

This person really knows some arithmetic, at least he can help in the early days.

Ye Chang was secretly happy in his heart, and connected to the second question, in line with the principle that one question is more difficult than the other, the second question is the question of irrigation and water release, this kind of question of pouring water into the pool while releasing water, once tortured Ye Chang in elementary school to death, today he took it out to test people, and his heart was quite happy.
