In the quiet and cold palace of Yangxin, two figures suddenly appeared out of thin air.

Ren Baqian was still holding a huge cardboard box and a small bag in his hands. After seeing the surrounding scenery, he lowered his head and looked into the empress's hand, and there was nothing.

"What I just had in my hand disappeared in an instant." The empress said, looking at her left hand.

After the second medicine bath, Ren Baqian's strength is about 150 pounds now, and the box in his hand is almost the same as the empress. He originally wanted to see if he could take some of the empress, but now it has been proven that it cannot be done. The things disappeared directly. I don't know if they were left on the earth or somewhere during the shuttle.

"Your Majesty!" Qing Yuan and Hong Luan's voices rang behind them, and the empress retracted her hand holding Ren Baqian like an electric shock.

"When is it now?" the empress turned around and asked.

"Your Majesty, it's my time." The two of them walked to the empress and bowed.

It looks like the two of them stayed here after the empress left.

It is between 11 o'clock in the middle of the night and 1 o'clock in the middle of the night.

"Is there anything going on in the palace?" the empress asked again.

“Peace and nothing.”

"You two go down first." The empress waved.

After the two left, they looked at the box in Ren Baqian's hands and asked, "What is it?"

Ren Baqian asked someone to tighten the box into the house and the two of them came back, and she had not had time to ask.

"A device that uses sunlight to melt steel is used for demonstration. After preparing, I made glass and mirrors, and made a larger equipment to melt Damoshan little by little. I thought that there might be complaints about building a factory to make glass, so I prepared such a thing, and I guess others had nothing to say." Ren Baqian patted the box and said.

This is a solar furnace that also shows its own abilities.

He was not unclear about his current situation. His attitude of dying from the Golden Palace that day and Tao Jiyuan's attitude at the beginning could tell him a lot.

If you don’t count this, you will get the same conclusion even if you put yourself in your shoes.

Therefore, he has to show some things to others. When his abilities are recognized by everyone, it will be much more convenient to do various things in the future. After all, he doesn't like to be questioned in everything.

"Okay." The empress nodded and turned back to the couch: "Tomorrow you are ready to tell me that I will let Erzhi Lao and some people watch together."

"Yes. Then I'll go back first." Ren Baqian carried the box and walked out carefully, and went outside to find two guards to help him send him back to Pingleyuan.

After returning to Pingleyuan, Ren Baqian first practiced "Ruyi Temple" and then fell asleep on the bed.

The next morning, Ren Baqian saw that the sun had risen, so he asked the guards to move the box to an open space in Pingleyuan.

Anyway, just demonstrate this only requires an empty and unblocking sunlight.

Ren Baqian opened the box, revealing a metal plate in the shape of a pot lid. It was about one meter in diameter and had grids on it. There were two boxes inside the box, and there were small lenses neatly arranged, which were said to have two thousand yuan.

I have to say that this job is quite troublesome, and the thick-handed and thick-legged guards of the ancient tribe couldn't help. Ren Baqian was afraid that they would destroy the metal plate with force, so he had to do it himself. It took more than an hour to install the lenses, and his arms were sore.

The two guards didn't leave, and just watched Ren Baqian busy there not far away, wondering what he was doing.

Occasionally, when they saw those small lenses, they subconsciously felt that this thing was very precious.

"Come on, help me take it." Ren Baqian said to the two of them, and went to find a branch himself.

"Turn this towards the sun at this angle." Ren Baqian told the guard step by step.

The light shone in the disc, like a treasure, and another guard subconsciously wanted to get close to see.

"Don't get close, stand next to you." Ren Baqian was startled by his movements. The focus of the disk reflecting sunlight could directly melt the steel, not to mention a person.

"Okay, hold it, don't move." Ren Baqian commanded the guard to stand, while extending the branches to a position one and a half meters away from the center of the disc.

The moment the branches reach the focus, smoke comes out instantly and then it catches fire.

This scene made the two guards stunned. What kind of treasure is this disc?

Ren Baqian went back to the room and found a small copper ring, put it on the branch and reached towards the focus point. The branches were lit instantly, but in seven or eight seconds, the copper ring also began to melt, and in the end, only half of it fell to the ground.

The sun in this world is a little bigger and hotter than the earth, so the metal melts faster.

"Master of the Mansion, what kind of treasure is this?" The two guards were shocked and finally couldn't help asking.

Ren Baqian smiled but refused to answer, saying, "Go and notify Your Majesty... Forget it, I'll go by myself."

He asked someone to put the disc back into the box and put it in the house, and ran to the Palace of Yangxin to find the Empress.

"Your Majesty, I have done it. I have tried it just now, there is no problem." Ren Baqian said with a smile on his face.

"Well, I want to see what you have done. But at this moment, I don't have to inform Erzhi Lao, Tuwan and others that you can have a meal with me first." The empress said softly.

After the empress said that, she asked Hongluan to ask the guards to inform the second master of the Ministry of Revenue Tu Wan, Taifu Siqing Gu Yue, Ministry of Works Tong Zhenye, Army of the Army of Fenghou and others.

"Your Majesty, it takes a mirror to make such a solar furnace. I think it is possible to build a glass factory in the name of the palace. The glass and mirrors made can be circulated on the market or sold to rich people in other countries. I believe they are willing to pay a lot of money, and then use this money to purchase materials and transport them back and can fill the country."

"In the name of the palace?" The empress does not have much concept of making money.

"Yes, the palace sent people to do it. The palace opened its own shops and sold them to other countries. Then, it purchased the materials with the money sold, and sold them back to the country at a small price. This will not only allow the people to benefit and thank His Majesty, but also ensure the financial resources in the palace.

At the same time, it is completely controlled by the palace, and many things can be avoided, such as others intervening in it." Ren Baqian explained.

"That's fine." The empress nodded and said.

"Do you want to form a caravan?" asked the empress.

"Yes, it is imperative. After all, transporting items from one place to another and selling them will have huge profits and can completely fill the treasury when needed.

For example, if the cost of a mirror is half a tael of silver, it can be sold for five taels of silver in China, but it can be sold for fifteen taels of silver in other countries. This money flows into the country from abroad, so that the trade will make the country rich.

They have always sold their goods to us. Although they can fill in the various materials that Dayao lacks, as this continues, Dayao's wealth is flowing out continuously, and Dayao's wealth is used to support the nobles of other countries.

And we can also form a caravan, so that such trade circulation can form a balance. At the same time, we can also pass news from other countries back to the country through caravans." Ren Baqian simply talks about the economic knowledge that everyone knows on earth.

The third update, now we have doubled the monthly tickets. Please give me the next monthly ticket. If you can enter the top six of the new book monthly ticket list and keep it before October 1st, you will add eight chapters. (If you don’t save the manuscript, of course, it will be a little bit more.)

Thanks to the wandering zombies, thanks to Eli, thanks to the lord who is still in a mood for the reward. I owe another seven chapters.

I'll write another chapter and return it first.
Chapter completed!
