Chapter 59: The evil guest came to the door and let Guo Nu (Part 1)

‘If gear transmission is used, the gear material will become a problem. Iron gears are not easy to cast, and the friction of wood consumes too much, and copper is suitable. In that case, the cost of the windmill will be as expensive as that of the pharmacy pot. It will also attract people to worry about it if it is placed in the dam...’

‘The windmill only solves the power problem. If you want to successfully pump water from a low point to a high point, you can use the windmill to drive the bucket, just like a overturn, but the efficiency is too low and the bucket is too heavy. If the bucket is different, it is like in some time travel novels. It is possible to use the windmill to pump water in a pipe, which is in principle. The question is what material pipe is used and how to ensure the seal...’

Early in the morning, Zhang Qian took a charcoal pen and kept writing and painting in the study. As a liberal arts graduate student dog, almost all the physics knowledge he learned in junior high school was returned to the teacher. Therefore, he was so overwhelmed by a simple windmill pumping problem.

He wanted to give up several times and lift the windmills to drain the water and change it to a more easily achieved one-way water gate. However, before the industrial age, the Dutch had already used the windmills to "pull" a quarter of the land from the sea level, and he felt very unwilling. So he simply took the attitude of taking the postgraduate entrance examination and started a "struggle" with carbon strips and mulberry paper.

The result of the struggle was extremely tragic.

After "killing" seven large rolls of mulberry paper that was as long as ten feet long and more than a dozen cut carbon strips, a very abstract sketch was finally presented on the table in front of him.

But the specific details are terrible. If you look at it from the perspective of later generations, each part will be drawn in a mismatched manner and is seriously distorted. The parts are marked with few legs. If you just take it to the mechanical teacher in the university next to Normal University, the latter will definitely scream three times on the spot and vomit blood and die of death.

A "Mohist master" in the West, Murphy once said: Bad things either don't appear, but if they appear, they will be paired. After two and a half hours drawing the first chapter, Zhang Qian began to worry about the material selection of parts.

At this time, the manufacturing level of Datang was ahead of the world, and the manufacturing level of Chang'an City was unparalleled in the world. However, "leading" was only compared to this era, and it was mainly concentrated in weapons and astronomical instruments, rather than the manufacturing of civilian equipment. This "leading" was not popularized across the country.

Although Zhangjiazhuang is less than twenty miles away from the outer wall of Chang'an City, the skilled craftsmen near Zhangjiazhuang no longer know what gears are. As for the "high-end" concepts such as worms and bevel gears, everyone is even more disgusted.

In desperation, Zhang Qian had no choice but to sacrifice power transmission efficiency and mechanical precision and replaced most of the transmission parts with cowhide belts. However, the pipe used to absorb water became a mountain in front of him. After repeated searching and scraping, he finally came up with bamboo tubes, fire-baked sockets, and linen tung oil sealing. The sealing gasket of the simple water pump became the next mountain...

My head was getting more and more painful, and my eyelids became heavier and heavier. Every bone and joint all over my body began to protest, as if I had just finished a marathon, and then I returned to the final exam site.

"Du, du, du..." The collision of a string of wooden clogs and the floor slowly rang beside him, from far to near.

Immediately afterwards, ten fingers with the fragrance of flowers gently pressed near his temple, turning slowly in a clockwise direction.

Zhang Qian's fatigue quickly subsided, his eyes closed instinctively, and his body slowly leaned towards the back of the chair.

The person who came was Zijuan. He could guess just by the fragrance of the flower dew on his body and the rhythm of walking. Because he was in a comfortable mood recently and the nutrition of the food was also as good as before, the little girl's fingers were obviously more fleshy than before and were much more elastic. Pressing near a person's temple, it was soft and warm, not like ten dry and cold reed sticks as it was at the beginning.

"No wonder many people in later generations want their daughters. At least when she grows up, she knows that she feels sorry for her. "A comfortable moan, Zhang Qian's muscles are more relaxed, his eyebrows are stretched, and a sleepy feeling swept across his body quickly. "Not like his son, he always wants to please his mother-in-law!"

However, what happened to the cloth that was quietly pressing towards the shoulders? It was still wrapped very thickly, with at least seven or eight layers.

The sleepiness subsided and his muscles were tense. Zhang Qian's body suddenly sat upright and left the contact with Bu Duaner! Zijuan, who was secretly rubbing his shoulder with "Bu Duaner", was caught off guard and let out a "moaner" sound from his mouth, and fell to the side.

"You're crazy!" Fortunately, Zhang Qianshou's eyes were fast, and before Zijuan had intimate contact with the floor, he pulled her up. He wanted to slap her twice again so that she would not play with fire in the future, but found that her face had long been red as if it was burning, and there were tears in her eyes.

"Don't mess around, how old are you." Zhang Qian rolled his eyes helplessly and put Zijuan's body down. "If you have that skill, why don't you help me go to the workshop to take a few glances."

"I just saw it and came back from there. If you don't believe it, you smell it, you smell it!" Zijuan's voice was like a cat's cry. She twisted her body and leaned forward again, holding up her sleeve and letting him smell his wrist.

"Okay, okay, I've been tired of smelling this thing every day!" Zhang Qian slapped his wrist with his wrist not much thicker than the tender cucumber, and scolded him in anger, "Hasn't you told you a long time ago that children should not think randomly."

"I'm not young anymore. The Thirteenth Aunt of Zhang Duwei's family is only eight months older than me!" Zijuan refused to accept it and pouted and argued with a pout.

"Eight months are also old. Also, she is her, you are you. Don't talk to her in the future... Forget it, if she wants to come to play at our house, you can play with her. But don't listen to her fallacies!" Zhang Qian immediately knew what the problem was, and suddenly felt like a big head.

Since he was chatting with He Zhizhang, Zhang Ruoxu and Sun Anzu that day, he said, "Watching chess is bad, and the writers are envious. For those who watch chess, it may not be a kind of luck." The three old seniors have greatly pityed him.

Especially when he lives in Zhang Ruoxu, he simply treats him as his junior. Not only do he come and go around if he has something to do, he is the elder of the same clan and guides him to study hard and improve himself twice, but he also brought his female relatives here to chat and play with Zijuan.

The age difference between these female relatives is extremely large. The oldest is in his early forties. According to the customs of this era, it is more than enough to be Zijuan’s mother. The youngest is only half a year older than Zijuan, but has been included in the house by Zhang Ruoxu for more than a year. If it weren’t for the old seniors who were already old and too greedy for cups, they would soon have to pass on their family line for their Zhang family.

Are the women in the inner house dating? Of course, the topic of the conversation will inevitably be related to men. Zijuan was not concealed by Zhang Qian's house, but could not conceal the servants in the village, but Zhang Ruoxu's concubines. As a result, these female "elders" became anxious for Zijuan, rushing to pull her into the house, and quietly taught the secrets to attract men!

The "teacher" taught her wholeheartedly, and the "students" also learned seriously. However, today, the first time I put it into practice, I was not good at getting off the job. Not only was Zhang Qian not successfully tempted by Zijuan, but he was so "not doing his job" that she was so "not doing her job".

"I have told you that people are like fruit trees. Flowers bloom too early and they cannot grow up. Go to the village to see, those women who get married early are not thin and shriveled, and they all live to be forty years old, and they are full of diseases during their lifetime!" Based on the principle of stopping the unhealthy trends in time, he glared at Zijuan fiercely and continued to scold him sternly.

"Yes, but Aunt Thirteen said that women are only in bud when they are fourteen or five years old, and they are the most likable. If the flowering period is over, men will be disdainful!" This time, Zijuan became much more courageous and continued to refute with confidence.

"I told you all, don't listen to her fallacies!" Zhang Qian was so angry that he scratched his scalp, but he couldn't beat him, and he couldn't bear to scold him. It was not until he almost scratched his scalp that he finally remembered a trick, "Forget it, I think you are idle. You have nothing to do, right? If you have nothing to do, go and recite ancient poems!"

"I only know very few words. Mr., do you teach me how to memorize it? I know I was wrong, and I never dared it anymore. I am very smart and I promise not to teach me more than three times!" Zijuan also knew from the advice given by her senior in person that inviting favors should be cautious. Pretend to look pitiful and begged in a low voice.

"Okay, I'll teach you!" Zhang Qian glanced at Zijuan, and felt nervous in his heart.

The little girl, don’t give her any harm, and burn the fire to herself sooner or later. Therefore, you must find a long enough poem to make things difficult for her, and help her establish a correct concept of life.

Which song is suitable? It has a large number of words and can teach girls to be self-reliant. Don’t always think about serving people with sex. With this song!

In his mind, Zhang Qian quickly recalled the most painful poems he had when he was memorizing ancient poems, and he made a decisive decision: "Okay, I will teach you. This poem, ancient Yuefu, Mulan Ci. I will read one sentence, you will follow me to read one sentence."

"Well, my husband read one sentence, Zijuan read one sentence after that."

"Jiji and Jiji, Mulan is weaving in a family, and she does not hear the sound of the loom, but only hears the sigh of the girl." Zhang Qian stood up straight, made a strict look like a teacher, paced and recited loudly.

"Jiji and Jiji, Mulan is weaving in the same family, and she does not hear the sound of the loom, but only hears the sighs of the girl." The crisp female voice rang out immediately, sounding like bells and chimes playing together.

"Ask the girl what she thinks, what she remembers. The girl has nothing to think about, and the girl has nothing to remember." Zhang Qian nodded slightly and continued to teach.

"Ask the girl what she thinks, what she remembers..." Zijuan put away her shyness and studied hard and earnestly.

"Last night, I saw the military post. Khan ordered his troops. He had twelve volumes of military books, and the master's name was named after the volume. Grandpa had no eldest son, Mulan had no elder brother. I was willing to be a horse in the city, and from then on... "

"...The twelve volumes of military books, and the volume is full of master's name." Zijuan became happier and happier, his voice as if a yellow oriole came out of the valley. "Grandpa has no eldest son, Mulan has no elder brother!"

The voice stopped abruptly. She lowered her head and quickly glanced at her chest. In an instant, her face turned red again. She turned around and ran away in panic. The first update, I wish everyone happiness. The next one may be very late, and there is something to do today. The drinker
