As for Li Sheng himself, no matter how you say it, he is also a science and engineering talent who received formal education and training in later generations. Even if he is not a great person, he can at least be said to have a solid foundation.
And now, Li Sheng is building a steam engine and an internal combustion engine, although it is said that they have been developed...
But this energy efficiency, anyway... if Li Sheng wanted to travel back in time, he would not dare to show it to his instructor - no, he would not even dare to show it to his classmates. That energy efficiency... would be embarrassing to the old man.
But if you want to improve and improve, it is very difficult...
This is first of all, of course, because Li Sheng engaged in mechanical design in later generations, using computers and software, etc. But now...
Well, a good computer is not as good as a bad pen! Li Sheng can only comfort himself in this way...
Moreover, it is very easy to design a machine and create a prototype - of course it was not easy for the sages in history, but it is not difficult to restore it yourself.
But it would be troublesome to further improve it - think about Apple's introduction of new mobile phone features at its annual press conference...
The increase in workload sometimes simply increases exponentially, which is an exaggeration.
Of course, these are not decisive factors. After all... Li Sheng's status is getting higher and higher now, and he can do some shameless academic behavior, recruiting academic strongmen from Chengxi College or Lingzhou College to work for him.
For some parts that were not very important, not so difficult and complicated, but the workload was not small, Li Sheng directly left it to these ancients.
As for many subsequent tasks, such as building and testing the car, it can be left to Wei Ziyu and others. Anyway, I only need to be responsible for the most difficult part.
The problem is that there are too few "materials" that Li Sheng can use now.
That's right, mechanical design is often no different from making movies and writing articles. They also require materials. It's like designing a rifle. Can you skip all the original designs and come up with a purely new design? Trigger
You have to use it.
No matter how beautiful and easy-to-use the 416 rifle is, it cannot use the bolt, firing pin, trigger handle and other things. These are the materials.
But now a big problem facing Li Sheng is that... the "bolt", "firing pin", "trigger", and "handle" that should have been included are not complete!
In future generations, everything will be simple. As long as your design ability is excellent, in our manufacturing temple, China, you can find any "material" from the supply chain.
But it was different in the great Tang Empire...
First of all, the big problem is that Li Sheng has no rubber...
This is hard to say. After all, rubber is a key sealing material, and if you think about something like a steam engine, you will know how much it relies on sealing.
In addition to this, there are others. For example, Li Sheng now wants to design an automatic rifle.
This thing seems to be a purely mechanical thing. At first glance, it seems that it can be copied in ancient times... but in fact it is impossible. The first problem is the processing accuracy. The processing precision of assault rifles in later generations is higher than that of various large-scale weapons.
It's a famous brand watch - you can tell this by looking at the price.
In addition to these, the most critical problem is that Li Sheng has no spring in his hand.
Without a spring, you can't make a gun!
There is not even a spring, how can the word "automatic" be realized in an automatic rifle?... Just think about it and you will know that it is impossible.
But now, when Li Sheng is designing, he can only try his best to use various alternative designs to meet the needs.
For example, use steel sheets as reeds instead of springs.
But in this way, first of all, there are many aspects of the design work that are directly different from the textbooks Li Sheng read back then.
Moreover, many places want to use reeds instead of helical springs. Even just looking at it, it is completely impossible... and then calculating the various physical parameters makes people even more desperate.
In other words, Li Sheng worked on steam engines, internal combustion engines, and various No. 2 and No. 3 engines... None of this is as simple as it seems. Because of the severe limitations of the conditions, in many cases the difficulty is really not much different from that of a doctoral thesis...
But at this moment, Li Sheng was extremely excited.
Because the ear pick in Li's second hand, judging from the luster... it was clear that it was made of standard steel.
What Li Sheng didn't expect was...
Nowadays, craftsmen in steel mills can process extremely hard standard steel into such thin sticks?... If this is true, then things will be exciting.
Li Sheng now has a "spring" available!
If "design" is also a kind of battle, then the difference in "operation space" between the two cases with springs and without springs can be said to be worlds apart.
Li Sheng was so excited that his breathing became rapid, and he quickly grabbed Li Er.
This action made Wei Zheng, Du Ruhui, and Fang Xuanling stunned on the spot, but Li Jing's pupils changed immediately, and the words "There is an assassin" popped into his mind subconsciously...
But then Li Sheng didn't give in, he was breathing heavily, waiting for Li Er, and said, "Old Li... where did you get this ear pick?"
…
Li Sheng's sudden excitement made everyone nervous, but... But what everyone didn't expect was that Li Sheng actually asked about ear picking?...
When Li Sheng asked, Wei Zheng, Li Jing and others all turned their heads and looked over.
Just by looking at it, everyone couldn't help but have inexplicable expressions... This earpick didn't seem to be anything special.
Is this some kind of ancient relic? Some kind of fairy weapon?
That's not right either... The material seems to be silver, or standard steel... There doesn't seem to be anything special about it.
But Li Sheng's expression was as excited as if he had seen ten thousand taels of gold. Even... Let Wei Zheng say, he probably really saw ten thousand taels of gold, and Li Sheng's calm personality would not be so excited.
What's going on?...
The person involved, Li Er, was the most confused, because he couldn't even remember how he got the ear pick. It was prepared by the eunuch and maid from Kilometers away... How could he possibly know where it came from?
This is really...
But at this time, Empress Changsun and Changle looked at each other. Her mother and daughter could not get in a word while Li Er and the ministers secretly tried to extract policy ideas from Li Sheng, but they still chatted with Li Sheng while eating hot pot.
Very happy.
In this scene, Li Er didn't know where he got the earpick, but the mother and daughter really knew.
Empress Changsun said directly, "This is prepared by the maid in my family...it's not a rare thing, it's just an ordinary ear pick."
Empress Changsun didn't understand what Li Sheng was excited about, but since her son was curious about this thing, she just picked up what she knew.
When Li Sheng heard this, there were no details, and he suddenly felt anxious! ...
