The Tang Dynasty started from saving Empress Changsun

Chapter 31 Microscopes

As the lives of his family were concerned, Li Shimin's efficiency was very high, and the medicinal materials needed for Angong Niuhuang Pills were delivered in a large amount that afternoon.

It is not enough just to have medicinal materials, but also to have a detailed ratio to make a good medicine.

At this time, the experience of Sun Simiao, the medicine king, came into play. He quickly came up with a prescription based on the medicinal properties of these medicinal materials.

The next step is to make pills and wrap them in gold leaf for storage.But if you want to carry it with you and ensure that it does not deteriorate, you need certain means.

This was an unsolvable problem for the ancients, but it was not a problem for Chen Jingke at all.

I found a craftsman to make a batch of hollow silver balls, put the pills in and steam them on a steamer for a few minutes, and then sealed them while they were hot.

Common bacteria can basically be killed at a temperature of more than 80 degrees, and the high-temperature sealed container can also form a vacuum environment after cooling, which can ensure that the pills will not deteriorate for a long time.

Incidentally, canned food is made using this principle.

As for why silver balls are used...the emperor can't be allowed to carry a porcelain vase with him, it's too shameful.

There are two reasons why the more expensive golden ball is not used:

[-]. China is short of rich silver mines, and the price of gold and silver is almost the same before the influx of silver from America.And because silver is rarer, it is often used to make jewelry.

[-] Appropriate supplementation of silver element is good for the body.

In short, the officials soon discovered that the emperor, the prince and others had a beautiful silver ball on their bodies.It doesn't take long for the whole city to hang silver balls on their bodies.

And the styles are more strange and exquisite than the other, there are solid ones, hollow ones, hollow ones, mixed ones... There are all kinds of shapes and patterns.

Soon this trend spread across the country, and hanging silver balls once replaced hanging jade pendants, becoming another special style of the early Tang Dynasty.

With this shareholder style, silversmithing became the most popular profession, and silver jewelry merchants also made a fortune.

Due to a drought in a certain place, Li Shimin took the opportunity to issue an order to advocate diligence and thrift, and the royal family must set an example.

As a result, the entire royal eating habits have changed, delicacies from mountains and seas, fish and meat have been greatly reduced, more vegetables have been included in the recipes, and even alcohol has been banned.

It also forced the kings and princesses to strictly enforce it, even the married princesses. If there is any violation, the light one will be fined, the severe one will be cut down, and the most serious one will even be cut off.

As soon as this order came out, the royal family and relatives naturally complained endlessly, but the officials praised the emperor for his kindness, and the people also sang long live my emperor.

The prince was the first to respond and updated his recipe.Wei Wang Li Tai was not far behind. Not only did he change his diet, but he also started exercising to lose weight.

Sun Wuji, the Duke of Qi, announced the change of the recipe, and other ministers followed suit, whether sincerely or falsely.

For a while, Li Shimin's prestige reached a new high, and more and more people recognized the name of Renjun.

Chen Jingke, who was still trapped in the palace, didn't know this, and he devoted himself to intense study again.

Follow Sun Simiao to learn Taoist knowledge, and find Wang Bi and Wang Fusi's works to study, and by the way, modify Journey to the West.

He has not let go of his medical skills, and has to recite verses, medical records, and study various medical books every day.In addition, he also found a third thing for himself, practicing calligraphy.

Speaking of which, he had practiced calligraphy in his previous life, and what he copied was Zhao Mengfu's regular script, not to mention how beautiful the writing was, at least he could pass it.

It's just that I used a hard pen in my previous life, but I used a brush after time travel, and the characters have changed from simplified to traditional.

For a person who has hardly touched a brush, this change is not small, and it is not an exaggeration to say that he is practicing from scratch.

However, with the foundation of his previous life, his calligraphy has improved rapidly, and now he has written squarely, at least he can show it to others.

That day, he was sitting in the gazebo in the courtyard, changing Journey to the West, when he saw Yang Tianlu running over excitedly holding a box, and said, "Really Chen, the microscope you want is ready."

Chen Jingke quickly put down his pen and said, "Take it here and let me have a look, have you tried it?"

Yang Tianlu put down the box, and took out a bronze microscope from inside: "I've seen it, and it can be adjusted to..."

"multiple."

"Yes, the multiples can be adjusted, and putting the hair underneath is like a mace... amazing."

Chen Jingke tried it himself, and found that it was almost no different from the ordinary microscopes he had seen in his previous life, and the screw mouth for adjusting the magnification was also very silky.

God knows how much work they spent on making this screw port.

But soon he discovered a shortcoming: "Get a painter to paint it black."

Yang Tianlu asked in puzzlement, "Why?"

Chen Jingke said: "The reflection is not obvious now, and it will not work when observing particularly subtle things. Any reflection may affect the observation results, and there is no such problem when it is painted black."

Although Yang Tianlu didn't understand, he knew what Chen Jingke said was right: "Okay, I'll find a painter right away."

Chen Jingke stopped him and said, "Don't worry, is the telescope ready?"

Yang Tianlu slapped his forehead and said: "Look at me, I forgot all about it when I was happy, and it's done." He took out a cylindrical bronze pillar from the box and handed it to him.

Chen Jingke took it over and observed it carefully, twisted and pulled it with his hand to create an extra section, closed one eye and observed with the other eye.

Objects in the distance appear in front of the eyes as if zoomed in, the definition is quite high, and the lines on the bark can be seen clearly.

"That's right, tell the craftsmen that I've done a lot...well, I'll report their achievements to His Majesty."

The next day, Changsun Wugou came over for a routine physical examination. After taking the medicine for that month, her condition has been effectively controlled, and now it is just a routine examination to prevent recurrence.

Once the condition is under control and other things can be solved, the damaged vitality of the body is also recovering day by day. Those who are not familiar with her can hardly believe that she almost died more than a month ago.

After checking the body, Chen Jingke handed the telescope to her: "This is a small gadget that I made when I was making a microscope. It may have a small military use. Auntie will pass it to Your Majesty for me."

The eldest grandson Wugou was very relieved, what happened in the palace could be hidden from her eyes?
She knew everything about Chen Jingke making microscopes, and even those craftsmen made two copies of each one, and one of them was sent to her.

Whether it is a microscope or a telescope, she already knew about it, but she didn't say it.

But she was still very happy when Chen Jingke gave her the telescope, and she liked this nephew more and more.

The following rewards and the like are naturally indispensable, so I will skip them here.

Two days later, Yang Tianlu sent over a black microscope.Sun Simiao began to try to observe all kinds of tiny things as if he had found a treasure.

First of all, it is determined that the dirt on the body is indeed a breeding ground for various bacteria and germs, and there are countless bacteria in the raw water...

Iron-like evidence is in front of us, and a revolution to change customs has begun to brew.

But before that, Chen Jingke had to move first. After two and a half months, Zixiao Temple was finally built.
