Black technology UP master

Chapter 226 Lifting Weights Like Light!

It can be seen that at the moment, Mr. Dong is very curious about the wooden ox in his hand.

So much so that when Lin Chengqi's grandparents came to talk to him, although he responded politely with a smile, his eyes would involuntarily glance at the 'gadgets' in his hands from time to time.

Lin Chengqi discovered this detail, but he couldn't say much about it.

Fortunately, Lin Chengqi's grandmother also discovered this very carefully, so when Lin Chengqi's grandfather began to have a tendency to "can't stop at all", the grandmother naturally cut off meaningless topics.

So, a few minutes later...

"You live in a very happy family!"

At this moment, Lin Chengqi had already arrived in his bedroom, and including the man and the woman, Mr. Dong and four other people also squeezed into this small room.

Right now, the man and woman were standing at the door, while Mr. Dong and the fat middle-aged man were sitting beside Lin Chengqi's bed.

As for Lin Chengqi himself, he sat on the universal chair in front of the computer desk.

Although the person I am in contact with now is the dean of the headquarters of the National Academy of Sciences, Lin Chengqi is still able to give an appropriate definition of his status.

Therefore, when he and Mr. Dong were facing each other, they were conducting academic exchanges on the basis of 'equal' status.

It's just that he didn't expect that when Mr. Dong looked at Mu Niu for a while, when he looked at Lin Chengqi, the first sentence he said didn't directly mention Mu Niu.

Instead, it talked about Lin Chengqi's family issues that had nothing to do with his intention of coming.

To this...

"I always knew I was happy."

Lin Chengqi smiled and said, "So, I also hope that my relatives will be happier and happier."

Although this response was very abstract, Elder Dong still nodded his head in agreement.

then……

"very good!"

Mr. Dong held up the wooden ox and said, "Let's talk about it."

Lin Chengqi nodded.

Only then did Mr. Dong continue: "I have already seen your design."

"I have to say that this kind of gear module, which you call able to maintain a 'power cycle' state for a long time, is indeed a very creative structure."

"However, according to my many years of research experience, this kind of module should have very high requirements in terms of precision."

"I don't know what method you use to complete the production of these modules?"

After hearing this question, Lin Chengqi secretly breathed a sigh of relief.

because……

"Sure enough, it will cause great doubts in this regard!"

Lin Chengqi had already included the current situation in the scope of vigilance and prepared countermeasures.

and so……

"My hands are very steady, very steady!"

Lin Chengqi shook his right hand, with five fingers swinging back and forth like a dragon stick, and said at the same time: "Since Mr. Dong knows the existence of wooden cows and horses, he must have watched my second video."

"Just wondering, have you seen the other video I did?"

After hearing this question...

"Seen!"

Dong Yuanhong nodded and said: "That is indeed a very superb skill, especially when the three models were 'combined' at the end, the right hand of the 'man' in the middle just touched the head of the little girl on the left."

"This ability to control the position is indeed amazing."

After hearing Mr. Dong's evaluation, Lin Chengqi's mouth turned up slightly, and he said with a smile: "This is the reason why I was able to make the precision gear module inside the wooden cow."

"As I said just now, my hand is very steady."

"But in saying that, there is always something that can't directly express what I want to express."

"So, it would be better to use the word 'precise' to describe it."

heard...

"is it?"

Mr. Dong asked curiously: "How accurate is it?"

"Just let me show you."

Lin Chengqi bent down, and took out a piece of A4 paper and a mechanical pencil from the drawer on the right side of the computer desk.

He removed the keyboard from the computer desk, put the A4 paper on the computer desk, held the mechanical pencil in his right hand, and naturally turned the pen.

Then he smiled and said, "Next, I will draw two straight lines."

"Mr. Dong can arbitrarily give two different appropriate length values, as well as the angle at which the two intersect."

"I can just draw it."

Hearing this explanation...

"That's interesting."

Mr. Dong hadn't responded yet, but the fat middle-aged man sitting next to him not only said such a sentence.

but……

"I still say that!"

Mr. Dong asked again as if confirming: "Specifically, how accurate can it be?"

To this...

"Exactly!"

Lin Chengqi gave a very confident answer.

"it is good!"

Mr. Dong nodded, then turned to the man and woman standing at the door and said, "Go alone and bring me my toolbox."

"Yes!"

Hearing these words, the male among a man and a woman opened the door and walked out of the bedroom.

at the same time……

"These two should be guards with a lot of background!"

Lin Chengqi had already known the fact that this man and woman had been trained in combat through the information feedback given by Yuan Wen.

He knew even more that these two men were equipped with guns.

To be able to have a guard qualified to carry guns, one can imagine how high and important Mr. Dong's status in China is.

And right now...

"Let's start first!"

After Mr. Dong finished speaking, after Lin Chengqi nodded, he said: "The two straight lines are 13.756 cm long and 7.423 cm long, and they form an included angle of 29.3 degrees."

It is worth mentioning that, in fact, not only Mr. Dong, but even the fat middle-aged man "Zheng Qi" who came with him now thinks that after hearing this report, Lin Chengqi should more or less There will be some preparation.

but……

The next moment, a shocking scene happened.

I saw that Lin Chengqi raised his right hand very naturally, picked up the pen twice '唰唰唰', and drew two lines.

It takes less than a second.

From the beginning to the end, the extremely confident smile on his face never disappeared.

I didn't even look at the A4 paper.

For this result...

Mr. Dong didn't say nonsense questions like 'are you sure', but directly picked up the A4 paper and observed it carefully.

"Looking at it this way, it's really straight."

Zheng Qi leaned over and analyzed: "However, it's better to use an instrument to test it."

To this...

Lin Chengqi just shrugged.

As for Mr. Dong, after nodding his head, he put the A4 paper aside and said, "We will discuss this matter when the tools arrive."

"Now, tell me first, what kind of mechanical principles are these gear structures?"

heard...

Lin Chengqi smiled and nodded, "Okay!"

　PS: Thanks to the four book friends 'aiuds', 'd51v6h84', 'Chubingbingbin' and '蕝薱' for their rewards.

　　Due to my special reasons in real life, the update time will be later in the future.

　　However, fortunately, in the past two months or so, my writing speed has been greatly improved by changing [-] characters per day for a long time. Therefore, three updates of old books and two updates of new books a day are still enough work to be completed.

　　Thank you for your support!
