Ren Baqian came to the laboratory not only to look at the machine tools but also to obtain a thick stack of data.
This included standard atmospheric pressure, gravity, elemental table, air composition, soil composition, and so on. This was the basis of the development of science and technology in this world.
For these things, three experts went to the Yun Nation under the protection of the winged cavalry warriors.
Not to mention the novelty of what they saw and heard along the way, this data would at least allow Ren Baqian to modify some of the teaching materials at the academy.
For example, the atmospheric pressure in this world was 1.1 times that of Earth. However, Ren Baqian had done experiments at the academy and found that the boiling point of water was about 106 degrees Celsius, which meant that Lan City was more than 1,000 meters above sea level.
At the same time, the gravity in this world was slightly higher than that of Earth. These experts felt more tired when they first came to this world than on Earth.
According to their observations and some speculations, the planet in this world was larger than Earth, rotated faster than Earth, and was further away from the star than from Earth to the sun.
As for the specific data, it would take a long time to come up with it.
The air in this world was composed of only 72 percent nitrogen and 25 percent oxygen. There was one more rare gas than on Earth, which made up a total of 1.4 percent.
The biggest difference between this world and Earth was that there was an important gas in the air that made up more than 1.5 percent.
This gas was very active at high temperatures and could easily react with a variety of elements …
…
Ren Baqian stayed at Zhongshishan for a night and approved two batches of experts' applications to expand the sampling area. The next day, he returned to Lan City with the thick stack of data.
With these people, he had a lot less to worry about.
As expected, professional matters should be left to the professionals to handle.
After returning to Lan City, Ren Baqian stopped for a while on Jingyang Street.
There were three gates and four roads in Lan City. The intersection of the four roads was in the middle, which was also the most prosperous area in the entire city.
A little south of this intersection, there was a three-story brick building that was much taller than the other two-story buildings. The bricks were decorated with large pieces of white jade.
White jade was still stone, but its color was similar to white jade. It was a mineral deposit that had been discovered during a recent mine exploration and was more valuable as a decoration than its original material.
This small building was six storefronts wide, and with the white jade decorations, it looked quite luxurious.
It could be said that in the eyes of most people, the most luxurious building in Lan City was this newly built shop with the word "Silver" hanging on its door.
At this time, there were many people outside the bank. People entered and came out one after another, holding a few pieces of paper in their hands. Their expressions were slightly uneasy.
"Boss, can this thing really be spent?" One of the men leaned on the shoulder of the other man and waved the piece of paper in his hand.
"It … should be possible, right?" The burly man who was being held down had a face full of doubt. "His Majesty wouldn't lie to us!"
"I still owe the restaurant a tael of silver. I don't know if they'll accept this." The other man's face was also somewhat gloomy.
These were all people from the Public Order Bureau. If they were like this, then there was no need to mention ordinary people.
He was used to using silver and copper, so when he suddenly received this kind of new paper, he felt that it was unreliable.
"Didn't you see the notice? This thing can be exchanged for silver and copper here! "Another burly man said from the side.
"Nonsense, I want to see it, but the problem is that I don't understand it! They recognize me, but I don't recognize them! "
"Isn't this superfluous? Wouldn't it be better to just give them silver? "someone muttered.
Ren Baqian watched quietly from afar.
That's right, it was indeed superfluous at the moment.
After all, these banknotes weren't recognized by the people outside.
Regardless of whether they were used to buy things or do other things, they had to be exchanged for silver first.
However, this was, after all, a beginning.
When these people got used to using these banknotes to exchange for silver and copper, and when the people started to get used to it, these banknotes could be directly used for exchange in the market.
Ren Baqian had a series of plans to use these banknotes to promote them.
His goal was to allow banknotes to be used in most places in Dayao within three years.
"This is Her Majesty, right?" someone sitting on a horse said to the people around him while distinguishing the patterns on the banknotes.
They were Bai Shiying, the head of the Public Order Bureau, and Tie Yan, the head of the Department of Supervision.
Their salaries weren't even 100 taels of silver, and they were probably here to watch the show. They had changed the banknotes from the largest to the smallest denominations.
"It must be!"
"Her Majesty is actually drawn on this!"
"Who is this?"
"Zhao Prince Consort!"
"Eh? Look at the sun. Zhao Prince Consort is beside Her Majesty's banknote. "
"Her Majesty is beside Zhao Prince Consort's banknote!"
"The two of them are even looking at each other!"
"Why do I feel like I've been fed something? I'm suddenly in a bad mood. "
After the two of them finished speaking, they turned around and saw Ren Baqian smiling brightly.
"Zhao Prince Consort is here. You and Her Majesty … What did you say?" Tie Yan turned to look at Bai Shiying.
Bai Shiying frowned, pondered, and suddenly realized something. "Like chewing wax!"
"Is this how it is?"
"It should be!"
Ren Baqian said playfully. "Her Majesty will definitely be happy to hear that."
"Of course!" Bai Shiying laughed heartily. "I've even studied a few books."
"They are all in the stomach of a dog," Ren Baqian cursed.
The three of them exchanged some pleasantries and left in a hurry, saying that they were going to the brothel to take a look at something for their little babies …
Ren Baqian turned around and returned to the palace.
These banknotes were denominated in silver. The largest denomination was 100 taels of silver, which was equivalent to 100 taels of silver. Below that, there were 50 taels of silver, 20 taels of silver, 10 taels of silver, 5 taels of silver, 1 tael of silver … The lowest was up to 1 centimeter of silver, which was equivalent to 1.2 wen.
Embossed printing and watermarking were used to prevent counterfeiting.
Cotton and two other plants were added to the banknotes and mixed in a certain proportion to make the banknotes harder.
With these techniques, it would be difficult to imitate them for at least 20 years.
In addition, there was a warning on the banknotes that said, "Counterfeiters will be punished with capital punishment."
On the 100 taels of silver note was the portrait of the empress. She was looking sideways at the only blank spot on the banknote.
In the blank spot was his mercury, which was looking at the empress.
The 50 taels of silver and 100 taels of silver were polar opposites.
On the 20 taels of silver note was a map of Dayao, including the current Yun Nation.
On the 10 taels of silver were the aboriginals, the Jing Tribe, and the people of the Yun Nation.
On the 5 taels of silver were the armies.
On the 1 tael of silver was the train.
The empress was sitting in the palace and watching a TV series. She hadn't gotten tired of watching it for so many years.
She sighed when she heard the whimpering sounds coming from outside. She was back after two days of peace.
"Your Majesty!" Ren Baqian left Liu Hua outside. After entering the hall, he hugged the empress and casually complained, "When I came back just now, I saw the officers from the Public Order Bureau and the Inspection Bureau. According to them, we were like chewing wax …"
The empress thought for a while before she understood what he meant. Her face turned cold as she said, "They are itching for a beating again. They even dare to make up gossip about me!"
Ren Baqian agreed and said, "I think so too."
First, set a small goal. For example, remember in 1 second: Bookseller's Mobile
