Deng Bao prepared all the materials Qin Yu needed from Yeting Palace.
The materials are not complicated, they are just what you need to make a telescope.
However, Qin Yu had to study it carefully. The large telescope he made was more complicated than an ordinary telescope.
Shen Binglan accompanied Qin Yu, showing a rare look of curiosity.
"This...can this thing really look at the moon?"
Shen Binglan looked at Qin Yu and couldn't help but ask.
Obviously, this fairy who doesn't eat fireworks from the world is also very curious about looking at the moon.
"Yo..."
Qin Yu looked at Shen Binglan in surprise, "What? Miss Shen is also interested in this matter?"
Shen Binglan nodded without thinking.
Seeing that Shen Binglan was so serious, Qin Yu didn't give in. "That's right, the thing I made is called a telescope. It can see very far away. If it is successfully made, we can see the moon on the moon from here."
Real situation.”
Hear this.
Shen Binglan subconsciously looked towards the sky.
She once again felt that Qin Yu's intelligence was unparalleled in the world.
Looking at the moon is no different from spying on an immortal. Shen Binglan couldn't help but wonder if Qin Yu would be able to fly in the future.
He accomplished a lot of things that ordinary people would never dare to think of.
Qin Yu was sitting in front of his desk assembling the telescope. The aperture of his telescope was quite large.
The principle of the telescope is not very complicated. It is composed of an eyepiece and an objective lens. The eyepiece is what the eye looks at, and the objective lens is on the other side.
It uses the optical principle. The light source of the observed scene is parallel light. When the parallel light passes through the lens, it will form a focus, and then the eyepiece is used to magnify the image.
Qin Yu is relatively proficient in physics knowledge, so making a telescope is not a problem.
Shen Binglan watched quietly from the side without saying a word.
The more she looked at it, the more strange she felt, where did Qin Yu get these strange ideas.
at the same time.
Xiao Nan ran over from the direction of the martial arts arena in a fancy outfit, panting.
"Brother-in-law, what good things are you studying now?"
Xiao Nan looked at Qin Yu and asked curiously.
Qin Yu didn't raise his head and said calmly: "Telescope."
"telescope?"
Xiao Nan was stunned and asked: "Then...what is that?"
Qin Yu pointed to the sky.
Xiao Nan followed Qin Yu's finger and looked towards the sky, wondering: "Flying things?"
Qin Yu shook his head, "It's for looking at the moon, to see what's on the moon."
Xiao Nan was startled, "Looking... at the moon? Brother-in-law, are you exaggerating?"
In Xiao Nan's mind, the moon is a very sacred thing. Qin Yu actually wants to look at the moon?
This is a very bold move.
This is no ordinary moon-gazing, this is spying.
But Xiao Nan was also very curious, because he also wanted to see what was on the moon.
Qin Yu continued to assemble the telescope, polishing it from time to time, "You will know if you are exaggerating tonight."
With that said, he raised his head and looked at Xiao Nan, "What's wrong with you?"
Xiao Nan was stunned and nodded quickly: "Yes, yes, yes...I have something..."
He almost forgot about the real thing.
Qin Yu lowered his head and continued to assemble, "Tell me."
Xiao Nan squatted on the ground and complained: "Brother-in-law, these wolf cubs from the Three Thousand Battalion are really delicious. I calculated the money spent on eating meat, and the money in my private treasury will not reach the middle of next year."
Qin Yu was stunned and asked: "Is it so exaggerated?"
"Isn't it?"
Xiao Nan looked distressed, "It snowed last year, and there were already few grassland sheep and the price was very high. It was not an option to eat like this. But if there is no oil and water, the soldiers would not be able to bear such a heavy training pressure."
Xiao Nan likes the army and cares more about the soldiers' food, clothing, housing and transportation.
"hiss......"
Qin Yu thought and put down the parts in his hands, "This is something that really needs to be considered."
There was a pause.
Qin Yu asked: "Is pork cheaper? It also has more oil and water."
Xiao Nan waved his hand, "Pork is not good. The smell is too fishy, and it will be difficult to eat when cooked."
Hear this.
Qin Yu remembered that pigs in this era were not the main force of meat.
On weekdays, dignitaries and even scholars don't like to eat it.
Nowadays, the six domesticated animals that people domesticate are horses, cattle, sheep, pigs, dogs, and chickens.
Needless to say, the importance of horses and cows is written into the law, and whoever eats them will be unlucky.
As the main source of meat, sheep are naturally popular, but ordinary people cannot afford it. It would be good if the common people can have enough to eat. Mutton is eaten by dignitaries.
Therefore, Xiao Nan provided mutton to the soldiers of the Three Thousand Battalion, which was already very luxurious.
But Xiao Nan couldn't stand it and was about to be crushed.
So pork is naturally the main force.
But there was no pig-stewing technique in this era, so the smell of pigs was too strong, and no matter how good a chef was, he couldn't make delicacies with pork.
So only the common people would eat some on weekdays.
There is no way, because besides that, there is no meat at all except hunting, but hunting is not that easy.
However, the reproduction and fattening speed of pigs are still very fast.
As long as the problem of pork's fishy smell can be solved, pork will definitely become the main force of meat, and it is delicious and not expensive.
Moreover, this problem cannot be solved by others, but Qin Yu can solve it.
He can solve all problems with his pig-managing skills.
Qin Yu said calmly: "In this case, you send someone to collect some piglets, and we build a pig farm."
Xiao Nan: "......"
He felt that Qin Yu was taking what he just said as fart.
Seeing Xiao Nan's tangled look.
Qin Yu explained: "You don't have to worry about the smelly pork problem, I can solve it."
Xiao Nan: "???"
Shen Binglan: "???"
Both of them looked at Qin Yu with wide eyes, full of disbelief.
Can......
Can the problem of fishy pork be solved?
Isn't this too exaggerated?
Are there any problems in this world that Qin Yu can't solve?
How come any problem is no longer a problem when it comes to Qin Yu?
It's really like a god.
"Brother-in-law, you...are you kidding?"
Xiao Nan looked at Qin Yu with wide eyes.
Although he has absolute trust in Qin Yu, making pork not smelly is not as simple as making something.
Pigs are animals and living creatures, and the smell of pork is the smell that penetrates into the pork.
Xiao Nan really couldn't think of anything Qin Yu could do.
Besides, if there is a way, no one in history can think of it?
"Can what I say be false?"
Qin Yu said calmly: "Just do it, and you will know when the time comes. You can't explain it in a sentence or two."
