Chen Dali is an old craftsman in the glass workshop.

As the only seventh-level worker in the glass workshop, Chen Dali has his own unique skills whether it is firing glass or grinding lenses.

Sometimes you can't learn this kind of thing even if it is taught to you in detail.

Especially for ground glass, the most important test is the feel and vision.

This simply cannot be expressed simply in words.

Therefore, the top-notch telescopes and magnifying glasses produced by the glass workshop are all ground by Chen Dali himself.

"Your Majesty, this lens has been ground according to your requirements, and the carpenter has also made the frame of this microscope. Just put the lens on it and you will know what the effect will be."

Chen Dali felt a little pressure when he saw Li Kuan personally squatting in the glass workshop for the past two days.

"Put them on the frames and see how they look."

In order to improve the success of microscope production, Li Kuan spent a lot of points from the system to redeem a microscope and put it in his own dedicated laboratory.

Then according to the structure of the microscope, we prepared the drawings and arranged for skilled carpenters to make the basic frame.

Even the lens barrel and the screw focus adjustment thing have been installed in advance.

"Your Majesty, by just putting two lenses together, can the magnification power of a magnifying glass...microscope be increased to hundreds or thousands?"

Tong Zhou stood aside and asked not very confidently.

"The magnifying glass is just a piece of lens, and basically the best one is only more than 20 times. But the microscope has two lenses, the eyepiece and the objective lens, which are combined together for viewing. The equivalent magnification is the multiplication of the two lenses. So we are now

The microscope being built can have a magnification of about 500 times. If we increase the magnification of a single lens in the future, it is not impossible to expand the microscope to a thousand times."

Li Kuan was still willing to explain its working principle to Tong Zhou, the most important user of the future microscope.

In fact, its principle is not as complicated as imagined.

It can even be said that the principle is very simple, and it is rare to produce excellent lenses.

In later generations, there is a saying that online games will ruin a life, and SLR will ruin three generations.

Although this is a joke, it also shows how expensive high-end lenses are.

Why are premium lenses so expensive?

Because the top quality lenses are hand-ground by top craftsmen.

Like this telescope and microscope, as long as the lens is powerful enough, you can make an excellent product no matter how much you do with other things.

"Magnify to five hundred times, a thousand times? Then...can our microorganisms be observed directly through this microscope?"

Tong Zhou looked at Li Kuan expectantly.

"Why did I name this thing a microscope? It's because it's a mirror that displays microorganisms. Do you think the microorganisms you're talking about can be seen through this microscope?"

Li Kuan looked at Tong Zhou with a smile.

This guy is a little worried about gains and losses now.

But it's normal.

In Chang'an City, Guanshishan Academy and the impurities in "Science" are now being discussed after tea and dinner as a joke.

The word microorganism has become a "hot word" in Chang'an City in recent days.

Even some people who are illiterate may have heard of this thing.

As the instigator, Tong Zhou's mental quality is not as good as that of Li Kuan. Although he firmly believes in his speculation, after all, he does not have the vision of God like Li Kuan.

So the pressure everyone endures is completely different.

"Your Majesty, the eyepieces and objective lenses have been installed, and the reflector is also installed on the mirror holder. Do you want to give it a try and see how it works?"

Although Chen Dali really wanted to see for himself whether the effect of this microscope was as powerful as Li Kuan said.

However, at the critical moment, he still figured out who was the boss.

"Bring over some of the sleeping beakers, let's first take a look at what's in this seemingly clear and transparent water."

Li Kuan did his part to prevent the microscope from being placed on the table, closed one eye, and faced the objective lens with the other eye, and then began to operate the microscope.

Since the mirror base is made of wood, and even the screw adjustment knob is made of wood, the operation of this microscope is relatively insensitive.

However, Li Kuan quickly found the feeling.

After all, he was already able to use the microscope he redeemed from the system very skillfully.

Now it's just a copycat, and you can master it with a little operation.

"Your Majesty, the water is here."

Chen Dali personally placed the beaker filled with water next to the microscope.

Li Kuan raised his head, picked up a piece of glass, dropped a drop of water on it, and put it on the microscope.

Then, when he used the microscope again and adjusted the focus, a different picture appeared in front of him.

"Tong Zhou, come and see what is different about the world in this drop of water. Is it as clear, clean and peaceful as it seems to the naked eye?"

Li Kuan did not speak, but directly asked Tong Zhou to come over and operate the microscope.

Tong Zhou, who had been coveting this microscope for a long time, would not carry forward the tradition of respecting the elderly and loving the young at this time.

He pretended not to see Chen Dali's curious eyes and sat directly where Li Kuan was sitting just now.

I saw him take a deep breath, then follow Li Kuan's example just now, close one left eye and put his right eye against the eyepiece.

"ah!"

Tong Zhou just looked at the camera and immediately raised his head as if he was electrocuted.

Then he closed his eyes hard and opened them again.

Then return to the microscope.

The situation in the camera is the same as before.

This is not an illusion!

These little things that are constantly swimming are the microorganisms His Royal Highness the King of Chu mentioned, right?

It turns out that there are so many microorganisms in a drop of water.

Tong Zhou stared at the camera intently, as if he wanted to remember everything in his heart.

"Director Tong, can you also let me take a look at the effect of this microscope? This way I can find the direction for improvement."

Chen Dali couldn't hold back his curiosity after all.

When he saw that Tong Zhou was staring at the microscope attentively for five minutes with no intention of getting up, he urged him.

"Your Majesty, I think this microscope is really amazing. You can actually see microorganisms through it. To put it bluntly, it is the greatest invention in the fifteenth year of Zhenguan."

Tong Zhou reluctantly gave up his seat to Chen Dali, and then talked to Li Kuan.

"The current magnification of this microscope is not high enough, and the clarity of the microorganisms seen is still not enough. If the magnification can be increased and the clarity can be improved, more things can be discovered.

Moreover, many improvements can be made to this microscope, which can be used to view water droplets, wood chips, animal hair and other things. The requirements for the microscope are also different. Some things have poor light transmittance, so you need to think carefully to see them clearly.

Method. In short, this microscope should still have a lot of room for improvement."

Li Kuan just used the microscope redeemed from the system yesterday, and now that he is using the copycat version of the microscope, he naturally cannot feel any joy or surprise.

However, his performance made Tong Zhou admire him even more.

His Royal Highness the King of Chu is so humble.

After inventing such a great microscope, he was not complacent at all, but came up with so many improvement suggestions in a short period of time.

I still have to learn more from His Royal Highness the King of Chu. I can't think it's great just because I came up with a theory about microorganisms.

Tong Zhou stared at Li Kuan with gleaming eyes.

Li Kuan couldn't help but hesitate.

I'm interested in your talent.

But I'm not interested in your people.

…

In the Xuanzheng Hall, Li Shimin was immersed in a pile of memorials.

"Your Majesty, His Royal Highness the King of Chu would like to see you."

Li Zhong gritted his teeth and interrupted Li Shimin who was busy.

Li Zhong has been very busy these days.

There were so many talks about microorganisms suddenly popping up in Chang'an City, so Baiqisi naturally had to pay close attention to them.

Originally, Li Zhong thought that Datang Daily wanted to engage in a back-and-forth debate with other newspapers, but in the end, there was no movement at all.

Even Li Kuan's men have not been on the streets of Chang'an City for several days.

Now that he suddenly came to see Li Shimin, Li Zhong felt that he definitely didn't come to chat with Li Shimin after having a full meal and having nothing to do.
