The glass-making project is in full swing.

The first batch of sand and gravel was transported to Qin Shuihan's tool room.

Looking at the bags of sand, Lin Yi instructed: "First grind this sand into powder, then add lime, and put it in the furnace to melt." ”

Qiu Qiansong looked at her curiously, how could this rumored new princess also like to tinker with things.

He glanced at Qin Shuihan again, the corners of his mouth were slightly raised, and he stared quietly, this doting look seemed to be a long, long time ago.

Qiu Qiansong stroked his beard, he remembered that when the former princess was alive, he showed this expression.

From a certain point of view, the prince is also very dedicated, and he likes women who tinker with things.

But if this is the case, the eldest lady of the Nangong family seems to be very aggressive, and I heard that she has made a carriage that can shoot hidden weapons.

Qiu Qiansong touched his eyebrows again, the woman didn't let her eyebrows, women like to tinker with these things these days.

Lin Yi held Qin Shuihan's arm and watched the workers grinding the sand stone with a stone mortar, and always felt a little strange.

"Water cold, isn't there a method of animal grinding? Does a donkey grind tofu and use it to grind sand? ”

Looking at the row of workers, Qin Shuihan also felt that these methods were a little slow, so he discussed the grinding method with Qiu Qiansong.

"Lord Wang, it's not difficult to grind. It's just that the old man hasn't understood what the princess wants, so let's see if we can burn what the princess wants? ”

Qin Shuihan took a sip of tea, hooked the corners of his mouth slightly, and doubted Yiyi, so he showed her Yiyi's determination.

"Old Qiu, let's make a bet."

Qiu Qiansong's beard was cocked.

"Good! Lord, a word is a certainty! The old man wanted Wang Meng's calligraphy and paintings. ”

Qin Shuihan raised his eyebrows, it was just Wang Meng's calligraphy and painting, a trivial matter.

Then it is a word. Yiyi can practice what you want to do, and you will make a top-notch secret weapon. ”

Qiu Qiansong looked at him suspiciously.

"The prince wants to be a peacock feather?"

"Just tinker with anything."

Qin Shuihan put down the teacup and walked out, leaving Qiu Qiansong in his heart.

The prince is cheating!

Lin Yi circled along the shagang furnace again.

After all, it was ancient times, there were no advanced instruments, and two hours had passed since the workers had ground the sand and stone.

Lin Yi sighed, she knew that when it came to real operation, there would definitely be a steady stream of questions waiting for her.

But you must put your mind in order, what you want to do is a modern item!

She took a few deep breaths, walked over to the worker, and commanded, "Mix this powder with lime and put it in the furnace in a ratio of four to one." ”

The workers immediately followed her instructions.

Lin Yi wrote down the mixing ratio and walked to the iron-making furnace again.

I saw that some other workers kept filling up the fuel.

After a long time, the sand in the container was still the same, and there was no change at all.

Lin Yi remembered that adding some sodium carbonate could effectively reduce the melting point, could it be that the proportion was wrong, or did he remember it wrong?

Looking at the raging fire, she was a little restless.

Then we tried different proportions of the mixture.

The result is still the same.

The sand is still the same sand, not a little bit of melting.

Qin Shuihan couldn't stand it, so he grabbed her distressedly, and after a busy day, he ate a few bites, and then went on like this.

"Yiyi, the hour is not early, it is better to go back today and come back tomorrow."

Lin Yi looked at the moon hanging in the sky with a sad face, and she nodded unwillingly.

Something must have gone wrong, isn't that silica sand?

Or is there something wrong with those limes?

Without saying a word, she climbed into the carriage and tried to figure out the manufacturing process.

Qin Shuihan held her in his arms, he just wanted her to be happy.

"Yiyi, you can't rush everything."

Lin Yi closed his eyes and rubbed his chest.

It's so nice to have him around!

Suddenly, Lin Yi was resurrected with full blood.

I can't be discouraged, compared to those great people, I have only tried for one day, and I can't call it hard work at all, and I will fight again tomorrow!

"Shui Han, can you let Lei Qing send me tomorrow? You're busy, you don't have to accompany me. What I want to make, I won't make it so quickly, but I won't waste the fruits of their labor, I must make glass! ”

Qin Shuihan smiled slightly, this is his Yiyi, he knows her too well, as long as it is what she wants to do, it seems that ten cows can't pull it back.

"Don't rush, take your time, I trust you."

But what exactly is that "glass", Qin Shuihan is looking forward to it more and more.

For two days in a row, Lin Yi went out early and returned late.

Although she tried several more recipes, the sand was still scattered in the container, and there was still no change.

Early this morning, Lin Yi got up early as usual to go to the tool room in the suburbs, only to see Leng Fang looking like she wanted to speak and stopped.

"Leng Fang, what's wrong?"

Leng Fang shook her head and got into the carriage with Biyue.

Lin Yi lowered his eyes, he went to see Leng Bin together just now, and his legs and feet recovered well, and there was nothing abnormal.

But since Leng Fang didn't say it, she didn't ask any more.

In mid-January, it has long ceased to snow in the capital, and it seems to have passed the most severe cold time.

Lin Yi lifted the curtain and saw that the snow on the eaves on both sides of the road was getting thinner and thinner.

She looked at the porch of the ancient deep courtyard mansion, and she really never got tired of looking at it.

The thing called the corbel on the eaves pillar amazed her every time she looked at it.

The hollow carving, the fine carving, the full three-dimensional sense, the characters are lifelike, jumping on the paper.

Today's sunlight also seems to be gentle.

Lin Yi closed his eyes, looking forward to some progress in today's glass production.

When I opened my eyes again, the word wood flashed through my mind.

Wood, parallel bars?!

Today is the day when the carpenter comes to the house to install!

"Biyue, let Lei Qing stop! Let's go home first! ”

Biyue didn't know why, but she quickly stopped Lei Qing.

Lin Yi smiled at Leng Fang.

"Today is the day when the carpenter came to install the parallel bars, I've been too busy lately to forget, why don't you remind me?"

"Princess..."

Although Lin Yi hopes to solve the problems encountered in the manufacture of glass as soon as possible, she always feels that she is a doctor, and saving lives is her job.

The carriage turned back to the Hanwang Mansion, and happened to meet the carpenter who came over with a shelf.

Steward Wu had already sent two servants to lead them into the house, and from time to time he gave the carpenter a hand.

is worthy of being the most powerful carpenter in the capital, not only perfectly understanding Lin Yi's meaning, but also making a load-bearing corbel at the right-angle junction.

If you look closely, you can see that there are still carved patterns on it.

Although it is a simple parallel bar, it surpasses the parallel bars.

Watching the carpenter fix the parallel bars in the house, Lin Yi's heart burst with a sense of accomplishment, if this set of things can be perfectly preserved to modern times, it will shock how many archaeologists and doctors!

"Leng Bin, let's start practicing today."

Lin Yi's voice was high, and there was joy between the lines.

Biyue and Leng Fang glanced at each other, although it was indeed a happy thing that Leng Bin's treatment could enter the next stage, but why was the princess so excited?

Lin Yi carefully determined Leng Bin's wound, and it took ten days to recover like this, maybe it was because of his medical skills and good stitches.

She pursed her lips in a smug manner.

At this time, Qin Shuihan had just returned home, and when he saw Lei Qing's carriage, he couldn't help but be stunned, Yiyi didn't go to the tool room?

It seems that she has been exhausted in the past few days, so she is estimated to rest in Jinghan Pavilion.

He changed out of his court clothes and immediately walked to Lin Yi's bedroom.

Yiyi is not there?

"Lily of the valley, where's the princess?"

"Back to the prince, the princess is in the cold guard's room."

Qin Shuihan pondered for a moment and immediately rushed to the guest room.

Seeing the little servant in the house leading two men dressed as carpenters to come, he remembered in a blink of an eye that this was what Yiyi had said before.

Seeing Qin Shuihan, Lin Yi jumped beside him like a little rabbit.

In the past few days, except for meeting him at night, the two of them have not had the opportunity to meet during the day.

"You're back?"

Qin Shuihan saw her smile like a flower, and unconsciously pinched her little face.

"So many people!"

Lin Yijiao snorted, made an ugly appearance, and turned around to pick up the crutches next to the screen.

"Give!"

Leng Bin took the crutches and looked at them again and again, the shape of the two sticks handed by the princess was really weird.

He raised his cane horizontally in his hand, wondering if he should get on the ground.

Lin Yi's eyes widened and he looked at him in disbelief, but after thinking about it, they had never seen this thing, so they had to bring it over and show it to him.

But it was originally built according to Leng Bin's height, and the crutches were too tall for her.

Everyone's eyes widened as they waited for her instructions.

Looking at their expectant expressions, Lin Yi frowned and pouted at Qin Shuihan.

"Come here and demonstrate."

Qin Shuihan was also very curious about how to use this crutch, and immediately walked over obediently.

I saw Lin Yi put the cane under Qin Shuihan's armpit, but unfortunately he was too tall, as if he was holding two toys.

"You, squat down."

Qin Shuihan obediently squatted to the height of Lin Yibi's stroke, and his crutches just supported his shoulders.

I see, I don't need the strength of my wrist to support my body, but I didn't expect such a simple bracket to be so mysterious.

Leng Bin nodded suddenly in realization, he took the crutches and tried to prop himself up.

"Come, you slowly move to the side of this parallel bar, hold on to the parallel bar and try to walk, the strength should be on the ball of the forefoot."

Leng Bin moved slowly, he grabbed the parallel bars and moved slowly, and bean-sized sweat droplets rolled down his forehead.

Every step is indescribably difficult.

But he wants to walk! Want to stand up!

Leng Bin struggled to move back and forth, and saw that the people around him were sweating for him.

"Stop!"

Lin Yi swallowed his saliva.

Among all of them, she was the most nervous, and with every small step Leng Bin, her heart rose to her throat.

Lin Yi patted Leng Bin's shoulder.

"That's enough for today! Walking is a gradual process, you practice three times a day, one round trip today is enough, one back and forth tomorrow, insist on three days and then increase to two back and forth, and so on. Wait until you reach ten rounds, and then I'll teach you the next step of training. ”

Leng Bin nodded vigorously, he believed Lin Yi.

Lin Yi knew that he was a person with strong willpower, but he was afraid that he would be too anxious, so he added: "You must do what I say, don't be impatient, if the hamstrings that are connected are broken, I won't be able to connect." ”

She glanced at Leng Fang again, thinking that this sister would definitely strictly supervise her younger brother.

Sure enough, Leng Fang also nodded immediately.

After that, Qin Shuihan accompanied Lin Yi back to Jinghan Pavilion.

"Yiyi, how did you measure Leng Bin's height?"

Lin Yi smiled slightly and took a scarf casually.

She stretched out her hands, fixed it with one hand, adjusted the length of the scarf with the other hand to straighten it, and tied the other end of the scarf in a knot and handed it to Qin Shuihan.

"If you look at the length of the two knots, the distance between my arms, is it my height?"

Qin Shuihan gestured, it was really her height, and she couldn't help but feel very amazing.

He tried to make a gesture himself, and sure enough, the distance between his arms was the same as his own height.

"Yiyi, how did you find out?"

She smiled and teased him.

"Feel your body while you're asleep, and feel the pattern."

Qin Shuihan was stunned in place, touching his body while he was asleep?

When?

How can you touch yourself without noticing it at all?

Seeing Lin Yi lowering her head and trying to hold back her laughter, she suddenly realized that she was teasing herself.

He hugged her slender waist and tickled her, laughing so hard that Lin Yi couldn't breathe and kept begging for mercy.

"Are you teasing me next time?"

"Don't dare, haha... Don't dare! Hehe, I was wrong..."

"Kiss me."

Lin Yi gasped and quickly pecked.

"Insincere."

Lin Yi stared at him aggrievedly, obviously full of sincerity!

But Qin Shuihan stared at her and pointed to his lips again.

Lin Yi had no choice but to stand on tiptoe and kiss him.

Who knew that in the next second, Qin Shuihan immediately turned against the guest, and kissed Lin Yi softly.

"Don't... People now... Still... Hurry to the tool room..."

Lin Yi gasped slightly and buried her head in his arms.

Qin Shuihan took a few deep breaths and tried to suppress his desires, he didn't have any ideas, but he couldn't help it, but now he really wanted to hug her Yunyu.

"I'll go with you."

Lin Yi shook his head.

"Biyue, they can just accompany me, there is too much time spent on the road, and you can't help anything if you go, so you can only waste your time in vain. Shrewd! ”

Although Qin Shui was reluctant, Lin Yi really did take care of what he said, he couldn't help, and he did have a lot of official business to deal with.

In the end, one of the two went to the study, and the other rushed to the tool room to continue the busy day.
