"RMB, is this Jiaozi?" Zhao Yuanyan said, looking at the RMB.

Jiaozi is a kind of paper currency that appeared in Sichuan in the early Northern Song Dynasty. It was first created to facilitate the transportation of large-value coins by Shu merchants, but now it has been used throughout the Song Dynasty, so Zhao Yuanyan thinks it is Jiaozi.

"No, Jiaozi is a voucher issued by merchants, while RMB is a legal currency issued by the state." Ye Cunxin explained, "Jiaozi is unstable. Once there is a problem, the merchant may run away, and Jiaozi is just a piece of waste paper."

, and the RMB is a currency issued by the state just like your copper coins, so there will be no problem. If you want RMB, you can go to the bank to exchange it for gold."

"Bank, then go and change it."

"Do you know where the bank is?" Xiaozhuang asked Zhao Yuanyan.

Zhao Yuanyan nodded and said, "Isn't a bank a place where gold and silver are exchanged for coins?"

This is Xiaozhuang's ignorance. Banks had already appeared in China during the Song Dynasty. Their main business was to sell raw gold and silver, gold and silverware and gold and silver jewelry. They also provided currency exchange services, which was to exchange gold and silver for copper coins.

.

It records the exchange of gold and silver at the gold and silver shop, which was the bank of the Song Dynasty.

Xiaozhuang and Ye Cunxin took Zhao Yuanyan to the bank to exchange gold.

Afterwards, the two asked Zhao Yuanyan where he planned to go.

Zhao Yuanyan directly said that he wanted to visit the capital.

The two of them took Zhao Yuanyan to the train station and bought train tickets to Shangdu.

By chance, there happened to be a car. So the three of them got on the train and headed to the mall.

On the train, because it was a short-distance train, there were quite few people. Zhao Yuanyan asked the two of them what the train was. After the two explained clearly to Zhao Yuanyan, Zhao Yuanyan asked, "Can I buy the train?"

The two were confused on the spot, who would buy a train?

Zhao Yuanyan said formally, "The train can carry thousands of people at a time. It will be very convenient if we can buy it back."

The two people hurriedly said that trains cannot be bought, and trains can only run on the tracks, and special roads must be built.

To put it bluntly, Zhao Yuanyan's idea was put away. After arriving at the mall, he took a bus to Xinzheng Airport and took a flight to the capital.

Zhao Yuanyan saw the plane and asked if he could buy it.

Xiaozhuang and Ye Cunxin said decisively that they could buy it, but you couldn't afford it.

"This is a magical object that can fly into the sky, and you can actually buy it with money!" Zhao Yuanyan looked at the plane, opened his mouth, and murmured to himself.

On the plane, Zhao Yuanyan sat by the window and looked out the window, extremely excited, "I am flying alone, I am flying alone, this is something only an immortal can do."

When he arrived in the capital, Zhao Yuanyan got into trouble as soon as he got out of the airport. Why?

The bad thing was his face. When everyone saw it, they thought it was the celebrity coming, and they crowded around him in a noisy manner. Zhao Yuanyan was so frightened that his face turned pale and he was at a loss. Xiaozhuang and Ye Cunxin took Zhao Yuanyan with them.

He ran all the way and finally managed to escape.

"What's going on? Didn't you say nothing will happen? Why are there so many people coming to arrest me?" Zhao Yuanyan said it was too dangerous and he wanted to go back and take people with him. He wanted to come out with Huyan Bixing and the others.

"What they are looking for is not you, but the person who looks similar to you." Ye Cunxin and Zhao Yuanyan said.

"Didn't you say that he was an actor? How come there are so many people following him?" Zhao Yuanyan felt incredible.

"What a coincidence, that person is also on today's plane and is right behind us." Xiaozhuang came back and said after hearing the situation.

"That's really an inch." Ye Cunxin said, "Mr. Zhao, we are in a prosperous age. This is what a prosperous age is. If you stay for a while, you will understand that actors will not be sought after in war-torn times, right?"

"Indeed, in troubled times, who would care about actors?" Zhao Yuanyan nodded in agreement, not knowing what he was thinking.

In the next month, Xiaozhuang and Ye Cunxin took Zhao Yuanyan to travel half of China. Zhao Yuanyan became more and more like a modern person. He could use all modern household appliances and could play with mobile phones and computers.

He even had fun pretending to be the actor.

Xiaozhuang and Ye Cunxin were surprised for a long time after listening to several lessons on Song History in college, so they asked him if he had any thoughts after taking the Song History class.

Zhao Yuanyan said that his nephew Zhao Zhen, who grew up in the palace and was manipulated by women, was completely useless. The subsequent emperors were even more incompetent and were manipulated by civil servants.

They are a bunch of trash, they don't even understand the reason why the emperor only has strong soldiers and horses, and there is no one who can lead the army.

Then I discovered another problem, that is, the elixirs are all poisonous, and they are all poisonous!!!

Zhao Yuanyan's face looked like he had opened a dyeing workshop, colorful and beautiful.

Xiaozhuang and Ye Cunxin looked at each other, looked at Zhao Yuanyan and asked: "Mr. Zhao, what's wrong with you?"

"Is the elixir really poisonous?" Zhao Yuanyan asked.

"Yes, elixirs are made of heavy metals, and they usually contain lead and mercury, which are poisonous." Xiaozhuang said.

At this time, the professor on the stage mentioned that lead poisoning can cause dizziness, headache, general weakness, memory loss, sleep disorders, dreaminess and other symptoms. Mercury poisoning can cause infertility, and children born from the Song Dynasty are likely to die.

Emperor Song Zhenzong probably died of heavy metal poisoning, and several of his sons should have died in the same way, and his son Song Renzong was also likely to be a user of the elixir. This is all very possible.

Following the professor's words on the stage, Zhao Yuanyan's face became darker and darker, and in the end it was almost like ink.

At night, Zhao Yuanyan kept pacing in the room, acting more and more irritated, "What should I do, what should I do, I'm taking it, how to treat it, why didn't I expect that so many emperors take elixirs?"

You’ll eat it to death!!!”

"Mr. Zhao, this heavy metal poisoning can be treated by us." Ye Cunxin looked at Zhao Yuanyan and couldn't help but said.

"Can it really be cured?" Zhao Yuanyan looked at Ye Cunxin with bloodshot eyes. "You have to know that many people in the royal family take elixirs. If it is poisonous, the world will collapse."

"It can be treated. In modern times, lead and mercury poisoning has a complete treatment plan." Xiaozhuang comforted Zhao Yuanyan, "In modern times, lead and mercury poisoning is also a relatively common heavy metal poisoning."

"When you go back this time, you can bring someone over to see a doctor." Xiaozhuang said.

"Can I come back if I go back?" Zhao Yuanyan always thought that he would never come back if he went back. But now that he heard that he could come back, he thought of those weapons again, and his expression changed again.

"You can come back. Zhuo Qun said that we can travel between the two worlds." Xiaozhuang said nonchalantly.
