"By the way, let's see if there is anything we can do to help. We should save time as much as possible."
Hearing this, Su Chen thought for a while and said, "Okay then, just stay and help me."
Su Chen agreed, and His Majesty Li Er turned to Wei Zheng and said, "Old Wei, you go back to Chang'an first and tell your family that you can put aside today's matters."
Wei Zheng nodded, knowing that His Majesty Li Er wanted him to go back and cancel the morning court.
Since this juncture was indeed very important at the moment, he quickly rushed back to Chang'an City and completed a series of tasks without saying anything else.
…
His Majesty Li Er and others were not idle either, and followed Su Chen to the heart of a secret room.
As soon as they entered the secret room, Changsun Wuji and Du Ruhui were shocked by the sight in front of them.
The layout of the secret room is not complicated, there are only some shelves and tables.
But these ordinary tables are filled with all kinds of glass products, which is really dazzling.
Although they all knew that Su Chen could make colored glaze, they were still deeply shocked when they suddenly saw these exquisite works of art!
Su Chen did not greet His Majesty Li Er and the other two, but went straight to the secret room and began to work on his own.
After a while, Su Chenjiu came over with two glass containers.
One is filled with off-white powder, and the other is filled with some kind of transparent liquid.
His Majesty Li Er looked at the two glass bottles in Su Chen's hands and asked, "What are they filled with?"
Su Chen returned without raising his head: "Chongtu!"
"What is heavy soil?" His Majesty Li Er said with tears in his eyes.
"You don't understand even after I tell you, why are you asking so many questions!"
Su Chen waved his hand and said, "Old Sun, come here and help me move this earthen pot out."
In this way, under the command of Su Chen, His Majesty Li Er and the other two people worked together to move a strange-looking earthen pot and placed it on the simple stove.
This earthen pot is a crucible made by Su Chen using fire-resistant clay.
And that heavy soil is the powder of barite.
The barite mine is located in the upper part of the vein, and there are many large mines floating on the surface in the Tanzhou area.
Because its appearance is somewhat similar to jade and slightly transparent, people near Dongting Lake often use it as a material to make decorations.
Because the price is cheap, there are a lot of these things on the mountain, but Su Chen brought this thing, and it is of great use!
Changsun Wuji and Du Ruhui also gathered around at this time.
Du Ruhui curiously picked up the bottle of transparent liquid, shook it twice, and wanted to put it under his nose and smell it.
Not far away, Su Chen caught a glimpse of this scene and was immediately frightened. He hurriedly shouted: "Stop moving, put it down quickly!"
"If this thing gets on your face, your face will be at risk!"
Du Ruhui was startled, his hand shook, and he almost dropped the glass cup to the ground!
Su Chen walked over in a hurry, carefully took the glass cup from his hand and put it on the table.
Seeing Su Chen's cautious look, Du Ruhui wondered: "What on earth is this?"
"Green vitriol oil!" Su Chen said seriously.
Green vitriol oil is the sulfuric acid of later generations.
In ancient times, it was something studied by Taoist priests who made alchemy.
This thing could easily hurt people if it wasn't done properly, so Su Chen didn't make it himself.
In the early years, he sent Lao Zhao and several others to find a Taoist temple for alchemy, and brought back a lot for storage.
After being stored for so long, it can finally be put to use!
After setting up the crucible, Su Chen quickly lit the fire to heat it.
After the temperature came up, he directed Changsun Wuji and others to start working.
First, he poured the heavy soil powder and water into the pot in a ratio of one to one. After blending, Su Chen took out a glass rod more than a foot long and handed it to His Majesty Li Er.
"Lao Li, you are the strongest here, so I leave this job to you."
"Remember, you must stir slowly in the same direction, and call me when it turns into a thick paste."
Because it was a matter of national importance, His Majesty Li Er did not show any pretense and started working willingly.
And since he hadn't done it himself for a long time, His Majesty Li Er was also very curious about it and worked very hard.
However, it didn't take long for him to feel that this work was really tiring.
This had been stirring for almost half an hour, and the contents in the pot showed no sign of turning into a mush, and his arms had already begun to feel sore and swollen.
"Are you sure this thing can become sticky?"
His Majesty Li Er couldn't help but said: "It has been so long and there has been no change at all!"
Su Chen said without looking back: "Continue to stir things up, it will take two or three hours no matter what!"
Two or three hours!
Hearing this, His Majesty Li Er's eyes almost went dark and he felt bad all over.
But for Datang, he could only continue to work hard.
Changsun Wuji and Du Ruhui were not idle either, being summoned around by Su Chen.
After a long time, His Majesty Li Er dragged his arms and said feebly: "Come here and see if this is okay?"
Su Chen came over, looked down, nodded and said, "That's enough, Lao Li, please step aside, we're going to start the next step."
Upon hearing this, His Majesty Li Er quickly stood up and gave way to Su Chen.
Then, Su Chen took the glass bottle containing green vitriol oil and slowly poured it into the crucible while stirring.
Later, His Majesty Li Er discovered that after adding the green vitriol oil, the liquid in the earthen pot was drying out rapidly.
"Why didn't you come earlier?"
His Majesty Li Er said with some displeasure: "My arms are already numb!"
Su Chen had no time to pay attention to him. He carefully looked at the changes in the crucible and carefully poured the green vitriol oil in little by little.
After another half an hour, Su Chen breathed a sigh of relief and said, "It's done!"
Hearing this, several people came over curiously.
I saw that the liquid in the earthen pot had completely disappeared and turned into a white powder at the bottom of the pot!
Changsun Wuji asked curiously: "What is the use of this thing?"
Su Chen flipped it carefully for a while, nodded with satisfaction, and said with a smile: "This thing is a rare treasure!"
If this thing he created were placed in future generations, it would have a scientific name: long afterglow material!
It has only one main characteristic - to shine.
2. This is also the simplest luminescent material Su Chen can currently produce.
Mix these things with colored glaze to make a luminous wolf totem.
He didn't believe it. This would not make those prairie barbarians crazy!
Just when Su Chen was about to take the powder to make the glazed wolf totem, he suddenly had a brilliant idea.
The Ashina tribe seems to have another name called Blue Turk. According to legend, the gods they believe in Qin have blue pupils.
