After lunch, Chen Ning's girlfriend Li Min took the initiative to take over the task of washing the dishes and successfully "squeezed" Liuyun out of the kitchen......

And Chen Ning, who had nothing to do, pulled aside Liuyun, who was about to watch the excitement: "Boss, I have a question I want to consult you." ”

Liuyun sat on the sofa, cocked Erlang's legs, raised his head and looked at Chen Ning with a smile: "Say it!" ”

Chen Ning sighed: "It's about complex surface processing!" ”

"Oh......" Liuyun put down Erlang's legs, sat up straight, and stared at Chen Ning with some surprise, "You're starting to touch the compressor impeller now?" ”

"Shhh Chen Ning glanced back at the college student trio who were watching the excitement in the cafeteria, and glanced back at Liuyun, "You have also been in the overhaul factory, and you have forgotten this attempt to keep the military project secret?" ”

Liuyun ignored Chen Ning's warning, smiled and asked a question that made Chen Ning's legs weak: "The new aero engine has been approved, right?" ”

Chen Ning's eyes waited widely: "Boss, how do you know?" ”

Liuyun shook his head with a smile: "The domestic version of Spey MK202 that has been finalized, the prototype is finalized by John Niu for more than six years, and it does not use such a complex surface processing technology. With your second brother's technology, you can't handle it, it must be newly designed. ”

Chen Ning kept looking at Liuyun: "Boss, are you hiding quite deeply?" ”

"General," Liuyun smirked, "By the way, what questions do you want to ask?" ”

"Wait a minute!"

Chen Ning returned to the room, took a drawing, and handed it to Liuyun......

Seeing the traces on the drawings that had been painted with a black paint pen, Liuyun smiled helplessly and looked up at Chen Ning: "Second brother, as for it?" ”

"Don't talk nonsense," Chen Ning glared at Liuyun, "Can you process this thing?" ”

Liuyun glanced at Chen Ning with a smile: "Comrade Chen Ning, is this an attitude of begging for people?" ”

"Boss, I've blown a bull with someone," Chen Ning stared at Liuyun pitifully, "Are you just watching your brother being ridiculed?" ”

Liuyun shook his head with a wicked smile: "I won't watch it, I'll close my eyes." ”

"Boss, now is not the time to joke!" Chen Ning straightened his face.

"Second brother," Liuyun raised his head and stared at Chen Ning with a smile, "Do you remember what I told you when I left the job?" ”

"If you want to machine more complex surfaces, you need to work on analytic geometry and differential geometry!"

Chen Ning's face flushed, and he was embarrassed to raise his head......

"This is only one time, not the next one!"

Hearing that Liuyun should fall, Chen Ning breathed a sigh of relief; But soon Chen Ning's brows twisted again: although mathematics is the traditional strength of the old Chen family, analytic geometry is fine, but differential geometry is too obscure......

Liuyun saw Chen Ning's difficulty, and reminded with a smile: "Sister-in-law should be a college student, right?" ”

A thief gleam flashed in Chen Ning's eyes......

Then, before returning to the factory, Chen Ning had already borrowed a textbook of advanced mathematics from his eldest sister and consciously started a sweet journey of progress......

And every day, I will be a cloud of human and dog food, and at the same time I am sad, I have to act as a coolie: I analyze various curves commonly used in the aero engine industry into a set of envelope curves that can be used for CNC machine tool processing.

After analyzing the surface, Liuyun summarized the commonly used processing and transformation methods for complex surfaces......

After helping Chen Ning get the complex surface processing, Liuyun still couldn't be idle: Chen Yang, the fourth elder who had been staring at Liuyun, asked Liuyun to write a textual report on the principle and operational feasibility of the shipbuilding method of the general section......

By the time Liuyun was really idle, it had already passed the small year; And Chen Ning's girlfriend Li Min finally knew why Chen Ning said that the old lady in the family was in charge......

Chen Jingfeng stayed at home for less than two days before returning to the fleet: in addition to being on duty at the end of the year, he also needed to hand over the "hot potato" pulled out from home - the shipbuilding method of the general section......

Liu Xiaohui has become accustomed to her husband's use of her own house as a hotel, and it has not been a day or two since Liu Xiaohui is in full charge of the family's finances and decision-making......

In the first few days, Liu Xiaohui was still a little unhappy with Li Min, who would take away her son's "property rights", but after being served by Li Min for a few days, and after straightening her hair, Liu Xiaohui "wanted to open it": although her son is too big to be a mother, she has half a daughter in her family......

Then, Liuyun was unlucky: Liu Xiaohui wanted to make some rice cakes and jujube buns for her in-laws to taste......

It's quite easy to make jujube buns, but it takes more "people" to make rice cakes: everyone else in the family doesn't know anything about making rice cakes, and it takes two people to make rice cakes......

After finding someone to help beat the rice cakes, Liuyun had to make it himself......

After making the rice cakes, Liu Xiaohui gave Liuyun some "tickets" and asked him to get some dried seafood......

Liuyun glanced at the Wuzhou ham hanging in the storeroom, reluctantly took the ticket, took a group of older children at home to the fishing port to borrow a boat, and then went straight to Peach Blossom Island......

The leader of the fishing team is still Cha Aiguo, and the team members are still those team members, but time seems to be off the string, and Cui Huayan has passed away: Although everything is like yesterday, Cha Aiguo has changed from an older leftover boy to a child's father......

Cha Aiguo, who has children, is not as sloppy as when he was single: he is dressed in brown overalls, not to mention whether the clothes fit or not, at least he looks much cleaner than back then.

Seeing the little doll following Zha Aiguo's buttocks, Liuyun took out a silver lock from his pocket and bent down to put it around the doll's neck......

Seeing the delicate silver lock on his son's neck, Cha Aiguo stared at Liuyun with a smile: "Yo, Master Yun, have you made a fortune?" ”

"It's not as good as you check the captain," Liuyun looked at Zha Aiguo with a smile, "Here in Yongcheng, who doesn't know that you caught three teams of crabs and made a fortune!" ”

"Well, don't bring me a high hat," Cha Aiguo glanced at Liuyun and asked with a smile, "Say, what's missing at home, we can live everything here now!" ”

Liuyun took a step back, tilted his head and looked at Cha Aiguo: "It seems that he has really made a fortune, and his waist is hard!" ”

Cha Aiguo smiled bitterly and shook his head: "Master Yun, don't be sarcastic about me, say, what seafood do you want?" ”

Liuyun glanced back at Chen Ning: "My brother Chen Ning, you should still know each other, right?" ”

"The master of Factory 591, how can you not know him?" Zha Aiguo smiled, "When the cold storage on the island was expanded, the refrigeration equipment was still purchased from Factory 591, right, Master Chen?" ”

Zha Aiguo smiled and stretched out his hand towards Chen Ning......

"Oh, and the three elites of Deputy Chief of Staff Chen's family!"

After shaking hands, Cha Aiguo picked up the child and led a group of people to the dry goods warehouse on the island......

After introducing the dehumidification equipment in the warehouse, Zha Aiguo looked at Liuyun with a smug face: "How is it?" ”

"It's okay," Liuyun smiled, "In China, I shouldn't be able to find a few, but ......"

"I know," Cha Aiguo sighed, "Not to mention Europabi, even if it is compared with the footbasin chicken, there is still a big gap." ”
