Chapter Fifty-Nine: The Wicked Guest Comes to the Door and Lets Guo Fu Go (I)

'If you're geared, the material of the gear becomes a problem. Iron gear casting is not easy, wood friction consumption is too large, copper is suitable, in that case, the cost of the windmill is about to catch up with the alchemy pot, too expensive, put it in the dam also attracts people's attention......

'The windmill just solves the power problem. If you want to successfully pump water from low to high, you can use a windmill to drive the bucket, like a rollover, but it is too inefficient and the bucket is too heavy. If it's not a bucket, but a windmill to drive a pipe to pump water, it works in principle, the question is what material to use and how to ensure the sealing......

Early in the morning, Zhang Qian took a charcoal pen and kept writing and drawing in the study. As a liberal arts graduate school dog, the little physics knowledge he learned in junior high school has almost been returned to the teacher. Therefore, the problem of being pumped by a simple windmill is like a bucket.

I wanted to give up several times, and changed the windmill to lift water and drain the water, and changed it to a one-way water gate that was easier to achieve. However, considering that the Dutch had already used windmills to "pump" a quarter of the country from under the sea level before the advent of the industrial age, he was so reluctant to do so. So, he simply took out the attitude of going to graduate school and launched a "struggle" with carbon strips and mulberry paper.

The results of the struggle were extremely tragic.

After "killing" seven large rolls of ten-foot-long mulberry paper and a dozen sharpened carbon strips, a very abstract sketch was finally presented on the table in front of him.

It's just that the specific details are miserable, and if you look at it from the perspective of later generations, every part is drawn out of proportion and seriously out of shape. And the identification of the parts is also missing arms and legs. If you show it to the mechanical teacher at the university next door to Normal University, the latter will definitely scream three times on the spot and vomit blood to death.

And a "Mohist master" in the West, Murphy once said: Bad things either don't appear, or if they do, they will come in pairs. After spending two and a half hours to draw the first chapter sketch, Zhang Qian began to have a headache with the material selection of parts.

At this time, Datang's manufacturing level leads the world, and the manufacturing level of Chang'an City is unparalleled in the world. However, the "lead" was only relative to this era and focused mainly on weapons and astronomical instruments, rather than on the manufacture of civilian appliances. Not to mention that this kind of "leading" has been popularized throughout the country.

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

In desperation, Zhang Qian could only choose to sacrifice power transmission efficiency and mechanical accuracy, and replaced most of the transmission parts with cow belts. However, the pipe used to absorb water has become a big mountain in front of him. After repeatedly searching his intestines and scraping his belly, he finally came up with a bamboo tube, a fire roasting sleeve, and a seal with linen tung oil. The gasket of the simple pumping machine has become the next mountain......

The head is getting more and more painful, and the eyelids are getting heavier and heavier. All over the body, every bone, every joint, began to protest, as if they had just run a marathon, and then returned to the final exam site.

"Tuk, tuk, tuk......" The sound of a string of clogs colliding with the floor slowly sounded beside him, from far and near.

Immediately after, ten fingers with the fragrance of flowers pressed lightly near his temples, turning slowly in a clockwise direction.

The tiredness on Zhang Qian's body quickly subsided, his eyes instinctively closed, and his body slowly leaned back in the chair.

The person who came was Zijuan, and he could guess it just by the scent of the flower dew on his body and the rhythm of walking. And because she has been in a good mood for a while recently, and the food is more nutritious, the little girl's fingers are obviously more meat than before, and the elasticity is much better. Pressed near the temples of a man, soft and warm, not like ten dry and cold reeds as at the beginning.

"No wonder many families in later generations want daughters, at least when she grows up, she knows that she feels sorry for adults." A comfortable moan came out of his mouth, Zhang Qian's muscles were more relaxed, his brows were stretched, and a sleepiness quickly swept through his body. "It's not like a son, who thinks about pleasing his mother-in-law all day long!"

But what's the matter with the ball of cloth that is quietly pressing against the shoulder? It's wrapped quite thickly, to say the least, there are seven or eight layers, and below, there seem to be two buttons and a washboard......

The sleepiness subsided, the muscles tensed, and Zhang Qian's body sat up straight suddenly, out of contact with Bu Tuan'er! Zijuan, who was secretly rubbing his shoulder with his chest, was caught off guard, made a "bang" sound in his mouth, and fell headlong to the side.

"You're crazy!" Fortunately, Zhang Qian's hands were quick and he grabbed Zijuan's forehead and pulled her up before she had intimate contact with the floor. I had the heart to slap her twice again so that she wouldn't play with fire in the future, but found that her face was already red as if it was burning, and there were tears in her eyes.

"Don't mess around, you're a little older." Zhang Qian rolled his eyes helplessly, and put Zijuan's body down, "With that kung fu, why don't you help me go to the workshop to take a few looks." ”

"I've just seen it, and I just came back from there, don't believe it, you smell, you smell!" The sound of the purple cuckoo is like a cat's meow. Twisting his body and leaning forward again, he raised his sleeve to let him smell his wrist.

"Okay, okay, I smell this thing every day, and I'm tired of smelling it for a long time!" Zhang Qian slapped his wrist, which was not much thicker than a tender cucumber, and counted it angrily, "Didn't I tell you a long time ago, children, don't think nonsense." “

"People are not small, the thirteenth aunt of Zhang Duwei's family is only eight months older than others!" Zijuan refused to be convinced, pouting and arguing on the side.

"Eight months is also big. Also, she is she and you are you. You don't talk to her in the future...... Forget it, if she wants to come to play with us, you will play with her. But don't listen to all that fallacies! Zhang Qian immediately knew what the problem was, and suddenly felt more and more like a fight.

Since that day when he chatted with He Zhizhang, Zhang Ruoxu and Sun Anzu over wine, he threw out the sentence "Watching chess is rotten, and the author is envious." For those who watch chess, it may not be a kind of luck", and then the three old-timers took great pity on him.

Especially lives in Zhang Ruoxu, and simply regards him as his junior. Not only did he come over for a walk around when he had nothing to do, and as an elder of the same clan, he instructed him to study hard and make progress, and on two occasions he also brought his female dependents over to chat and play with Zijuan.

And the age difference between these female dependents is extremely large. The longest of them is in his early forties, and according to the habits of this era, it is more than enough to be the mother of Zijuan. And the youngest is only half a year older than Zijuan, but he has been included in the house by Zhang Ruoxu for more than a year. If it weren't for the fact that the old-timers were already old and too greedy, they would soon have to inherit the lineage for their old Zhang family.

Do the women in the house interact, of course, the topic will inevitably be related to men. Zijuan was not accepted by Zhang Qian, and he could hide it from the servants in Zhuangzi, but he couldn't hide it from Zhang Ruoxu's concubines. As a result, these female "elders" were anxious for Zijuan, competing to pull her into the house and quietly teach her the secrets of attracting men!

The "teacher" taught with all his heart, and the "student" also studied seriously, but the first time he put it into practice today, it was not good for him to be a teacher. Zhang Qian was not only unsuccessfully tempted by Zijuan, but scratched his head at her for being so "unprofessional".

"I've told you that people are like fruit trees, if the flowers bloom too early, they won't grow well. If you go to the village, you can see that none of the women who got married early were thin and shriveled, and they did not live to be forty years old, and they were riddled with diseases during their lifetime! In line with the principle of stopping the unhealthy wind in time, he glared at Zijuan fiercely and continued to count sharply.

"But, Aunt Thirteen said that when a woman is only fourteen or fifteen years old, she is the most lovable. In case the flowering period is over, the man will disdain it! This time, Zijuan became much more bold, and continued to refute vigorously.

"I've told you everything, 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. It wasn't until the scalp was about to be scratched that I finally remembered a trick, "Forget it, I think you're idle." If you have nothing to do, right, if you have nothing to do, you can memorize ancient poems! ”

"I only know a few words, Lang Jun, can you teach me to memorize well. I knew it was wrong, and I didn't dare anymore. I'm smart enough to promise not to let you teach me more than three times! Zijuan also knew from the opportunity of the seniors that it was necessary to pay attention to proportionality when inviting pets. pretended to be pitiful and begged in a low voice.

"Okay, I'll teach you!" Zhang Qian glanced at Zijuan, and was secretly ruthless in his heart.

Little girl, don't give her a little hardship, sooner or later she will be on herself. Therefore, you must find a poem that is long enough to embarrass her, and by the way, help her establish a correct concept of life.

Which one is suitable? There are a lot of words, and it can teach girls to be self-reliant, and not to always think about serving people with Israel. There you have it, this one!

In his mind, he quickly recalled the most sinful poems when he memorized ancient poems, and Zhang Qian made a decisive decision: "Okay, I'll teach you." This one, Gu Yuefu, Mulan Ci. I read a sentence, and you read a sentence after me. ”

"Well, Lang Jun reads a sentence, and Zijuan follows him."

"Chirp and chirp, Mulan is a household weaver, I don't hear the sound of the machine, only the sigh of the woman." Zhang Qian straightened up, made a strict teacher's appearance, paced, and recited loudly.

"Chirp and chirp, Mulan is a household weaver, I don't hear the sound of the machine, only the sigh of the woman." A crisp female voice followed suit, sounding like bells and chimes in unison.

"Ask the woman what she thinks, and ask the woman what she remembers. Women don't think about anything, and women don't remember. Zhang Qian nodded lightly and continued to teach.

"Ask the woman what she thinks, ask the woman what she remembers...... Zijuan put away the shyness in her heart, and she studied well and seriously.

"I saw the military post last night, the Khan ordered a large number of soldiers, and the military book was twelve volumes, and the scrolls had the name of the master. Grandpa has no eldest son, and Mulan has no eldest brother. Willing to be a saddle horse for the city, ...... from now on"

“…… There are twelve volumes of military books, and the scrolls have the name of the master.! "The purple cuckoo is happier the more it backs, and the sound is like a yellow warbler coming out of the valley." Grandpa has no eldest son, and Mulan has no eldest brother! ”

The voice stopped abruptly, she lowered her head, glanced quickly at her chest, and in an instant, blushed again. He turned around and fled.
