The medical concubine said: Evil king, please go to bed

Of course, Gu Yan didn't know anything about Lingyun Academy, nor did she know that Chu Yu wanted to kill her again.

After seeing the glass bottle sent by Chu Yu, after the initial joy, she faced a real problem.

The glass of this glass bottle cannot be used as a microscope lens at all. Although natural glass is also called glass, it is actually very different from glass. What's more, what a microscope needs is a concave-convex lens, although she can also turn this glass into a lens. Concave-convex lenses, but the high price also discouraged Gu Yan.

Although I don't know the exact price, the things that Chu Yu sent over together with those things show that the price is high.

After much deliberation, Gu Yan had no choice but to give up the plan of using glass bottles as materials, and made a new plan——

That is to make the glass yourself, and then make the concave-convex lenses needed for the microscope.

Just do it, Gu Yan went to the place where she was writing just now, and wrote down the method of making glass.She had already learned how to make glass when she was studying in the military academy, and because she was interested, she also specially learned how the ancient Chinese people made glass, and could make some simple ancient glass.

At this moment, Gu Yan can be said to be extremely grateful that she has learned it, otherwise she would not be able to find modern materials to make glass in Donglin Country.

After writing the prescription, the next step is the matter of materials. The craftsman knows what is the most important thing about materials. Gu Yan thought, after putting the prescription in her sleeve, she went out and went straight to the building of the aseptic room. place away.

Because of the recent construction of the sterile room, the craftsmen in the mansion gathered there.

It happened that she also took a look at how the sterile room was built.

When Gu Yan arrived there, the craftsmen were discussing something in full swing. They were obviously very happy to see her come over, especially the leader Chu Gong.

"The servant has seen the princess." After Gu Yan asked him to get up, he hurriedly said, "Princess, you are finally here, otherwise the servants will almost quarrel."

After so many days of contact, it was not the first time that Gu Yan heard him say that. Generally speaking, it means that they have encountered difficulties again.

"Is there any problem again?" She smiled kindly.

"Yes." The guard nodded in embarrassment, and his already dull face became even more simple and honest. "Princess, look here, we really don't understand very well"

As he spoke, he handed the design drawing in his hand to Gu Yan, and said what he didn't understand.

Gu Yan looked down, because the sterile room needs to isolate bacteria, and the sterile room needs to stagger the door. At the beginning, what she said was just a brief introduction, so that the craftsmen had some debates about how to stagger the door.

"How about this, you are setting up a space in front of the sterile room, so that there is a buffer for the air, so that the air will be staggered." Gu Yan told the guards about the practice of modern sterile rooms.

Hearing this, the guard slapped his head and suddenly realized, "Yeah, why didn't the servant think of this?"

As he spoke, he stared at the design drawing in his hand for a while, and the more he looked at it, the more surprise he saw in his eyes.

"The intelligence of the concubine is really not comparable to that of a slave." He couldn't help sighing.

Gu Yan just smiled when she heard this.

This is not her skill, it is modern technology.The ingenuity of modern man.

But of course Gu Yan would not tell Wei Gong about these things.

She is not the original body, she will never tell others.

After solving Wei Gong's question, Gu Yan asked him about the glass material.

"Guardian, help me to see, have you heard of these things?"

Wei Gong took Gu Yan's list with some doubts, not understanding why the princess would ask these things.Still looking intently.

Seeing that he was busy, Gu Yan turned her gaze to other places.

The embryonic form and construction of the sterile room will only take time to complete. Thinking of this, the smile on the corner of Gu Yan's lips deepened.

After the sterile room is completed, there will be more things she can do.In her special sterile room, even Chu Yu couldn't figure out what she was doing.

Thinking that Weigong has already read the list, quartz sand, limestone, feldspar, boric acid, and soda ash.These things are the raw materials for making glass, most of which are materials needed for construction.

"I have heard of other things, but I don't know what this so-called soda ash is? I really haven't heard of it." The guard looked at the soda ash on the list again, and really couldn't think of anything with this name.He looked at Gu Yan apologetically, "Princess, a slave is really useless."

"This has nothing to do with you." Gu Yanzi couldn't possibly blame him for this, she is not an unreasonable person, not to mention she still has something to ask someone else, she just said, "Then can the guard find these things for me?"

As for soda ash, she can just use salt to purify it, which is not difficult.

Wei Gong showed a hearty and honest smile, "Since it is the request of the princess, the servant must help the princess find the things."

"Then I'll thank Gong Gong first," Gu Yan quickly thanked.

The guard looked terrified. "The concubine offends the slave, this is what a slave should do"

Afterwards, Gu Yan discussed with the guards about the construction of the sterile room before leaving. However, she did not return to Qianmo Courtyard immediately, but went to the kitchen to find a bag of salt before returning to her room.

When Zhu Yunjuanbi saw Gu Yan coming back with a bag of salt, her mouth was wide enough to stuff an egg.Especially Juan Bi didn't close it for a long time.

"I don't know if this is the princess?" Zhu Yun came to his senses first, and then asked Gu Yan, looking at the bag of salt on the ground.His eyes were full of doubts.

"I can't tell at the moment, Zhuyun, go to the small kitchen and boil a pot of water for me." There was no very good equipment in ancient times, and she could only use high temperature to refine.However, the salt in ancient times was not as refined as it is in modern times, but it should be easy to extract soda ash from it.

"Yes" Zhu Yun went to the small kitchen without a word.Juanbi was left alone in a daze.

It's night, the small kitchen of Qianmo Courtyard

All three of Gu Yan's master and servant stayed here. After Zhu Yun boiled the water in the pot, Gu Yan put some of the salt in the bag into it first, and asked Juan Bi on the side to continue adding firewood.

As the fire temperature gets higher and higher, the continuous high temperature makes the water in the pot start to boil continuously.Some even splashed out from the edge of the pot, leaving traces one after another on the desk, forming a puddle of water, spitting bubbles from time to time, like a goldfish hiding in it, but the difference is that this scene It made the table look extremely awkward.

Faced with all this, Zhu Yun and Juan Bi, who had no idea what their princesses were going to do, became more and more confused.The two looked at each other while Gu Yan was looking at the situation in the pot, both of them looked confused.

What the hell is the princess doing?

The two thought at the same time.But because she had never seen it before, she couldn't see anything from Gu Yan's actions.
