If you don't go back to the courtyard for a long time, you will definitely attract the attention of the neighbors in the courtyard, maybe you think that it is a bad rumor to find a secret son outside, gambling, etc., the so-called public mouth is gold, accumulating and ruining bones, and the reputation is bad, and the road in the future will not be good. So when eating breakfast together in the morning, Li Guocheng asked for the opinion of Xiao Xiao'e: she went back to her parents' house when she was bored during the day, anyway, there were not a few steps, and she went to pick it up at night and ate together, and then Li Guocheng rushed back to the courtyard, and when the backyard was asleep, he jumped over the wall and rode to Dongzhimen, and the next morning he rushed back to the courtyard to run into the courtyard, pretending to get up early to exercise.

Sister Huan felt sorry for Li Guocheng, and resolutely didn't need to be so troublesome, just wait for the backyard to sleep every night. But after thinking about it, I think it's still risky, often walking by the river, how can I not get my shoes wet, so it is recommended to come over 6 nights a week, and you can stay for a day on Sunday. At the same time, it is not safe for Xiao'e to stay alone in the small courtyard, and she is even more reluctant to have other people in the small courtyard.

As soon as he heard this, Li Guocheng also understood, it seemed that Dong Basket still saw something, and was packing up the assets of the family, preparing to be cunning and cunning, worthy of being called a man in the middle of the city, his sense of smell is still so sensitive. So I didn't insist, and said that I would go home from work on Saturday and go back to the courtyard on weekdays.

A month and a half has passed in a blink of an eye, and it has entered May, Wang Gong's drawings have also been completed, and the trio is checking.

"Are you sure you don't want to reprocess a lead screw?" asked Wang Gong.

"As you know, like lead screws and guide rails, we need special steel, and we definitely can't apply for it, and even if there is special steel, it takes time to release the stress," Li Guocheng explained again.

"What stress? What release", Wang Gong said suspiciously.

Li Guocheng secretly regretted that the release of steel stress was a common knowledge in later generations, and he accidentally said that he was bald just now, and hurriedly made up for it.

"In fact, there is a description of stress in ancient China, it seems to be a Mohist theory, I can't remember the specifics, XF scientists put forward the concept of stress in the last century, and also published a lot of related articles, which should be found in the library."

"Take our factory as an example, the steel plate produced by the rolling mill is generally no problem in a short period of time, but if the steel plate is large enough and put it for a long enough time, a slight warping will occur, which is the manifestation of internal stress release" Wang Gong nodded blankly, am I a secondary school student, why don't I even know anything in junior high school.

Seeing Master Yi nodding blankly, Li Guocheng hurriedly made up for it.

"There is a daily phenomenon, when we eat watermelon in summer, we gently cut a hole in the skin with a knife, and the watermelon will automatically crack, which is the manifestation of internal stress release."

"Well, that's the case, but the watermelon must be ripe thoroughly, otherwise it will be white when you cut it, hahaha..." , Master Yi understood, and he was familiar with watermelon.

"Lao Yi, this is not a matter of watermelon, it is stress release, I feel that Li Xiaozi understands it, but I just don't understand it a little."

"Lao Wang, then do you understand or don't understand, you have given me a whole cover."

"Two masters, this stress, I only know it by reading books, and I know a little bit about it, but I know how to release stress, the West commonly uses high or low temperatures, I don't know how to do it, but there is a stupid way, that is, natural release, the disadvantage is that the time is a little long."

"That's no problem, we have a lot of time."

"It generally takes 5~10 years", and the two masters wilted again.

"Therefore, if you use ready-made guide rails and lead screws, then there is no need to release the stress, which has generally been released, otherwise it will be deformed, and the machine tool will not be able to be used for a long time."

"As for our newly manufactured parts, due to their small size and narrow plane, after finishing, they will be released after half a year."

"Then let's check the drawings again, you have to take the problem of stress into account," Wang Gong asked with great interest.

Li Guocheng did not expect that today's remarks would trigger Wang Gong to start studying the stress-related knowledge of steel, and inadvertently started the research of this discipline in China more than ten years in advance, providing theoretical and experimental data support for the subsequent national precision equipment design. After Li Guocheng pointed out the direction of the stress relief method, Wang Gong did not need to take detours, only needed repeated experiments, and this is a rolling mill, which is unique.

After getting off work in the afternoon, I returned to the courtyard, and as soon as I entered the middle courtyard, I was blocked by Widow Qin's way home.

"Xiao Li, tell you a good news, my cousin is here, you will meet later", Li Guo knew that Qin Jingru was here.

"Sister Qin, let's tell you the truth, I have a partner now."

"Don't lie to my sister, every day is a factory, a courtyard house, two points and one line, and I haven't seen you on a blind date."

"It's my middle school classmate.,I didn't meet in a department store.,After a few exchanges.,Almost confirmed the relationship.,It's almost time to find a matchmaker.," the lie came as soon as he opened his mouth, and he believed it himself.

"Hey, then you're not blessed, my sister is an old rarity."

"Anyway, thank you Sister Qin."

"If you don't meet my sister, anyway, you haven't officially confirmed the relationship now, the so-called parents' orders, the words of the matchmaker", Widow Qin still seems to be working hard.

At this time, a twenty-eight-year-old delicate girl walked out of Jia's house, with a soft and slender waist, a slender and delicate figure, and the bumps must appear, making her buttocks appear firm and round, and the headlights are towering and eye-catching.

For a moment, Li Guocheng was a little tempted, and the girl opposite pretended to be shy, but her eyes already revealed a little pride, in their township, it was a bee and butterfly flying, taking and grabbing, not wanting to marry into the city to eat food, the threshold of the family had already been broken.

In a trance, Li Guocheng thought of this girl's alarming IQ, as if her nutrition had grown headlights. I am not the sea of law, and I can't cross sentient beings. Coupled with the clear and exquisite Qin widow, the future days can be imagined.

Besides, isn't she fragrant?! At the age of 28, he is in his prime; Everyone's ladies are beautiful, and it is the book that can never be finished; The expression is gentle, and every time it is the bliss of the western sky; Gentle and lovely, quietly watching, is the warmth of home; I am infatuated, but I am afraid that I will not give enough.

Nodding to Qin Jingru with a smile, Li Guocheng pushed the cart into the backyard.

"Sister, he is Li Guocheng, listening to your chat just now, he seems to have a partner."

"Say yes".

"Sister, do you think I still have a chance?"

"It's enough, with my sister's understanding, Xiao Li's heart is quite high, and I guess I can't look down on rural girls."

"Looks so spirited", looking at the moon gate in the backyard, his face full of regret and complaints.

"Well, isn't this Sister Qin? This is your cousin", He Yuzhu was attracted by Qin Jingru's beauty as soon as he entered the middle courtyard, his saliva almost flowed all over the ground, skillfully handed over the lunch box, approached Widow Qin's ear, and said in a low voice:

"Sister Qin, my own sister, introduce me to me", I didn't care, how ambiguous such an action was.

Widow Qin was struggling, and out of the corner of her eye, she saw Xu Damao, who had just entered the middle courtyard, and she became stupid and stupid at a glance. I was happy in my heart, remembered it, and deliberately pretended not to see Xu Damao.

"Come, cousin, this is He Yuzhu, the 8th level chef of the rolling mill, with a salary of 27.5, do you see, these two big houses are his family, there is only one sister Yushui, who will graduate from high school immediately, and after getting married, Yushui's house is He Yuzhu's", he introduced loudly, and pointed to the two main houses in the middle courtyard and said.

"Come, you go to Zhuzi's house first, sit, chat, and get to know each other", although Qin Jingru was not satisfied with the appearance of the stupid pillar, but his heart knot was to marry in the city, and then think about the object of the previous blind date, either a widow or an old ugly, compared to them, He Yuzhu's is still Zhouzheng, although he is in a hurry, but his age is less than 30. The conditions at home are good, so I want to see everywhere first.

Xu Damao watched Qin Jingru enter the stupid pillar's house, the fire in his heart rose, the wolf howled in his heart, and the inner construction was completed in an instant, it was by no means that he fell in love with the girl's beauty, but he couldn't let the ugly and old stupid Zhu Huo Huo be such a delicate girl, never. With a roll of his eyes, he sneered, turned around and walked out of the compound.

Widow Qin has been secretly paying attention to Xu Damao's performance, and after turning around and going out, she will smile and turn her head home, swaying from side to side almost breaking the door frame of her house.

"You really introduced Jingru to Silly Zhu, what do you think, you said that you will introduce it to the Li family."

"The Li family kid has a high spirit, and he didn't fancy Jingru."

"Then what should I do, I can't let them be stupid, otherwise it will be a little difficult in the future."

"Then what can I do, you resolutely don't let me marry Silly Zhu, but I seem to have seen Xu Damao."

Jia Zhang's family didn't pick up his daughter-in-law at all, they were all thousand-year-old foxes, what to talk about.

"Xu Damao?" , Aunt Jia thought about it, and then laughed.

"Then I'll rest assured, I'll just sit back and watch the show."
