Cinnabar has been paying attention to the farm recently, so she knows very well how much Su Jinli values this farm.

After hearing Su Jinli's words, she immediately said solemnly: "Master, rest assured, the slave and maid will definitely do their best to pay close attention to all the changes on the farm." ”

Su Jinli looked at her serious face, so she smiled: "Well, don't be too tired, the affairs of the farm are mainly in charge of Steward Du." All you have to do is go over there once a day and tell me how it's going. If you have any questions, remember to keep me informed. ”

Cinnabar nodded: "The slave obeys!" ”

As he spoke, Ping An came over with the palace steward.

When the housekeeper learned that Su Jinli wanted to see him, he didn't dare to delay for a moment, and walked all the way quickly.

After seeing Su Jinli, he saluted respectfully.

Su Jinli didn't like these red tape very much, so he didn't wait for him to finish saluting and said directly: "You sit down, I have something to do for you." ”

The housekeeper immediately said, "Princess, please speak." ”

Su Jinli didn't say anything polite to him, and directly said his request: "I asked people to make some fertilizer, but the effect is still uncertain, and someone needs to record it." You help me find a literate person to go to the farm and be responsible for recording the use of fertilizer. ”

When the butler heard this, he was a little shocked.

He knows a little about farming, but he doesn't pay much attention to the specific things like fertilizers.

Who knows, Su Jinligui is the princess, and she actually cares about such a trivial matter, not only letting people make fertilizer, but also finding someone to record it!

However, he was only surprised in his heart, and did not show it on his face.

The housekeeper agreed: "Don't worry, princess, your subordinates will make arrangements as soon as possible." ”

"Be careful when picking someone, it's better for this person to be familiar with farming, and don't let him mess around and damage the crops in the field."

"My subordinates understand."

"You go now, how to record it, I'll have someone tell you later."

"Yes, the subordinates retired."

The housekeeper simply took the order and went to help Su Jinli find someone.

He thought about it for a while, thought it was a good opportunity, and planned to look for it among the children and nephews in the family.

He's from the Northland, and his hometown isn't here. However, since he followed Chu Yan to the capital and became the housekeeper of the Qin Palace, he selected some useful people from the clan and asked them to move over.

However, he knew Chu Yan's temper, so he knew how to be proportionate, and he didn't directly stuff all the people into this Qin Palace, but assigned them some other tasks.

Now that Su Jinli wants someone, he thinks it's an opportunity, so he plans to use his own family.

As long as you do this errand well, you will definitely have a good future.

However, he had to beat it up, and he couldn't mess up the errand.

Su Jinli didn't know the housekeeper's careful thoughts, and after the housekeeper left, she went to the study and wrote down the record requirements.

In order to test the effect of this batch of fertilizers, it is natural to separate different control groups and record various data.

For example, plant height, plant condition, and the ratio of fertilizer to water, etc.

Su Jinli wrote down these requirements on paper, and then asked Ping An to take them to the housekeeper.

But what surprised her a little was that when she came back safely, she actually brought someone with her!

It was Liu Feng who was in charge of burning the glass.

Liu Feng didn't go in with Ping An directly to see Su Jinli, he was waiting outside, and after Ping An reported to Su Jinli, Su Jinli passed him in.

As soon as Su Jinli heard Liu Feng's request to see him, he knew that he must have achieved good results.

So can't wait to meet him.

However, as soon as he saw Liu Feng's appearance, Su Jinli frowned.

Liu Feng didn't look very good at this time.

Although he had already taken a shower, changed into clean clothes again, and his expression was very excited, Su Jinli could still see the tired look on his face.

Liu Feng's eyes were bloodshot, obviously the result of not sleeping all night.

Su Jinli couldn't help but be a little dissatisfied: "You stayed up all night last night?" ”

Liu Fengzheng was excited, but as soon as he heard this, he heard the dissatisfaction in Su Jinli's tone.

He suddenly became uneasy, and replied cautiously: "Back to the princess, the little one saw that the glass was burned, and he didn't dare to delay, so he took someone to make the glass for a night."

At present, some transparent glass plates have been fired, and at first the craftsmen were not skilled, and the pressed glass plates were filled with bubbles.

However, after many trials, the craftsmen have become more and more proficient, and there are fewer and fewer air bubbles in the glazed panels. The little one specially brought some over and asked the princess to take a look. ”

Su Jinli glanced at him in surprise: "It's so fast?" ”

However, thinking that Liu Feng had fired the glass many times before, it was estimated that she had already accumulated a lot of experience, and she felt that this speed was not too exaggerated.

Of course, Liu Feng was able to fire a good quality glass plate so quickly, and it took a lot of thought to think about it.

So she nodded and said with some expectation, "Where's the thing?" I'll watch it now. ”

Liu Feng opened the box he brought and carefully took out a boxy transparent glass plate, or glass plate, from it.

Su Jinli glanced at Ping'an, who immediately walked over, took the glass plate from Liu Feng's hand, and then sent it to Su Jinli.

Su Jinli took a closer look.

The pane of glass is fairly transparent, about three millimeters thick, and there are no air bubbles.

It should be enough to make mirrors and glass windows.

If you add color, you can also make colorful glassware and jewelry.

It's just that if you want to use it to make lenses, it's still a little worse.

Su Jinli thought for a while and asked, "Is the yield of this quality glazed plate high?" ”

Liu Feng immediately said: "The current output is not very high, but if you burn it a few more times, the craftsmen should become more and more skilled, and the output will definitely be higher at that time." ”

"Okay, but you still have to continue to find ways to improve the quality and strive to burn more transparent glass, I have a lot of use."

When the transparency increases, it can be directly pressed into a lens rough blank with a mold, and then polished to become the required lens.

When the time comes, you can create a large number of clairballs and eyes.

However, things like clairvoyance are military weapons, so she doesn't need to mix them, but she can make more mirrors and glasses, and magnifying glasses are not bad.

Clairvoyance or something, it's better to let Emperor Yongan worry about it.

Now that Liu Feng has burned the glass, it has been proved that the recipe in that strange book is correct.

As long as Emperor Yong'an knew the news, he would definitely be more concerned about the other things in that strange book.

The only problem is that once Liu Feng burns out the lenses, she may not be able to keep this person.

Why don't you make more mirrors to sell while the lenses haven't come out?
