Ren Baqian came to the laboratory not only to look at the machine tools, but also got a thick stack of data.

Including standard atmospheric pressure, gravity, elemental table, air composition, soil composition testing, etc., this is the basis for the development of science and technology in this world.

For these things, three special experts went to Izumo under the escort of the Feiqi.

Not to mention the novelty that I have learned along the way, at least this data can allow Ren Baqian to modify some of the teaching materials of the institution.

For example, the atmospheric pressure in this world is 1.1 times that of the earth. However, Ren Baqian conducted an experiment at the school. The boiling point of water is about 106 degrees, which means that the location of Lancheng is at an altitude of more than 1,000 meters.

At the same time, the gravity of this world is slightly higher than that of the Earth. These experts are more likely to feel tired when they first come to this world than when they are on Earth.

According to their observations and some speculations, the size of the planet in this world exceeds the Earth and its rotation speed is also greater than that of the Earth, and its distance from the stars is farther than that of the Earth to the Sun.

As for the specific data, it will take a long time to come out.

My colleagues have only 72% of the air component in this world, oxygen accounts for 25%, and rare gases have one more than the Earth, accounting for one or four percent.

The biggest difference between this world and the earth is that there is an important gas in the air, accounting for more than one-five percent.

This gas is very active at high temperatures and can easily react with multiple elements...

...

Ren Baqian stayed in Zhongshishan overnight and approved two batches of experts to go out to expand the sampling range. The next day, he returned to Lancheng with thick information with ease.

With these people, I feel much more worry-free.

Professional matters are indeed left to professionals.

After returning to Lancheng, Ren Baqian stopped in Jingyang Street for a moment.

Lancheng has three gates and four roads. The middle is the intersection where four roads gather, and it is also the most prosperous area in the entire Lancheng.

A little south of this intersection, there is a small building with three-story brick and stone structure, which is a little higher than other two-story buildings. Large pieces of white jade are pasted outside the brick and stone for decoration.

White jade is still a stone, but it looks a bit like white jade. It is a mineral discovered during the recent exploration and is used as a decoration with a higher value than its own material.

This small building has six wide facades and is decorated with white jade patches, making it look quite luxurious.

It can be said that in the eyes of most people, the most luxurious building in the entire Lancheng is the shop with the word "silver" hanging at the door that was just built.

At this time, there were many people around the bank, and some people entered one after another, and some people came out one after another, holding a few small pieces of paper in their hands, with a slightly uneasy expression.

"Boss, can this thing really be spent?" A big man lay on the shoulders of another big man and raised the piece of paper in his hand with one hand.

"It should...can't do it?" The man who was being stalked was full of doubt on his face. "Your Majesty can't lie to us!"

"I still owe someone a tael of silver in the restaurant. I don't know if he will collect this thing." Another big man also had a little annoyed.

These are all people from the Public Security Department, and they are all like this, not to mention ordinary people.

I was used to using silver and copper, but suddenly I sent it to my hands and became this new piece of paper. No matter how I thought about it, I felt unreliable.

"You didn't read the notice? This thing can be exchanged for silver and copper here!" Another big man spoke aside.

"I want to read nonsense, but the problem is that I can't understand them! They recognize those words, but I don't recognize them!"

"Isn't this an unnecessary move? Isn't it over to just send money?" someone muttered.

Ren Baqian watched quietly from a distance.

That's right, it's really a waste of time.

After all, the people outside do not recognize these banknotes.

Whether it is used to buy things or do, it needs to be replaced with silver first.

But this is the beginning after all.

When these people became accustomed to using these papers to exchange for silver and copper, and the people began to become familiar with them, these banknotes could be directly used for exchange and circulation in the market.

Ren Baqian has a series of plans to promote these banknotes.

The goal is to allow most places of Dayao to trade directly with banknotes within three years.

"Is this your majesty?" someone sat on his mount and said to others as he distinguished the patterns on the banknotes.

It is the secret of the Public Security Department Bai Shiying and the secretariat of the Supervision Department.

The salary of these two people is not enough for 100 taels of silver. I guess they came here to watch the fun, and they changed them from the maximum denomination to the minimum denomination.

"Sure, sure!"

"Your Majesty was actually drawn on it!"

"Who is this?"

"Prince Zhao!"

"Huh? Look at the sun, there is Prince Zhao next to this picture of Your Majesty."

"Your Majesty is next to this picture of Prince Zhao!"

"The two still looked at each other!"

"Why did I feel like I was fed something? I suddenly felt bad."

After the two of them finished speaking, they turned their heads and saw Ren Baqian smiling brightly.

"Prince Zhao is here, why are you really talking to His Majesty...?" Tie Yan turned his head and looked at Bai Shiying.

Bai Shiying frowned, thought deeply, and suddenly realized: "It's like chewing wax!"

"Is that the word?"

"It should be true!"

Ren Baqian was so funny: "Your Majesty must be happy when you hear these two people say this."

"That's it!" Bai Shiying laughed and said, "I have read two books."

"It's all in my stomach." Ren Baqian complained.

The three of them exchanged a few greetings, and they left in a hurry, saying that they were going to the brothel to see the little babies...

Ren Baqian turned around and returned to the palace.

These banknotes are based on silver, with a maximum denomination of one hundred, equivalent to one hundred taels of silver. Below are fifty silver, twenty silver, ten silver, five silver, one silver... and the lowest is up to one cent of silver, equivalent to 1.2 cents of silver.

Concave-convex printing and watermarking are used to prevent counterfeiting.

Cotton and other two plants are also added to the banknotes, and mixed in a certain proportion to make the hardness of the banknotes stronger.

With these technologies applied, it will be difficult for people to truly imitate them within at least twenty years.

In addition, there is a warning font on the banknote that "the counterfeiter is sentenced to death."

On the banknote of 100 silver is the empress's avatar, looking sideways at the only blank direction on the banknote.

In the blank position is his own mercury, looking at the empress.

Fifty silver and one hundred silver banknotes are completely opposite.

Above Twenty Silver is the map of Dayao, including the current Izumo.

Above Ten Silver are the ancient tribes, the Jing tribes and the Izumo people.

Above the Five Silvers is an army.

A silver is a train.

The empress sat in the palace and was watching the TV series. She said that she hadn't gotten tired of watching it after watching it for so many years.

When I heard the "Woo Woo Woo Woo Woo" sound from outside, I sighed. I had just been quiet for two days and I was back now.

"Your Majesty!" Ren Baqian left Erhua outside, entered the hall and hugged the empress, and complained: "When I came back just now, I saw the Public Security and the Supervision Commissioner. According to what these two said, we are like chewing wax..."

The empress thought about it and understood the meaning of the word, and her face turned cold: "They are skinny and itchy, and they dare to arrange my gossip!"

Ren Baqianshen agreed: "I think so too."
