After that, Cai Wei boiled the rice flour into rice juice, used the rice juice as a culture medium, and implanted Penicillium for seven days.

After seven days, the culture broth is filtered through white yarn and rapeseed oil is added to dissolve the fat-soluble substance. Since penicillin is water-soluble, the water underneath the oil dissolves the penicillin.

Lu Ying was only dazzled, and she didn't know why it took so long to make a medicine, and the process was so complicated, which was more troublesome than Taishang Laojun's alchemy.

But as long as Cai Wei likes what Cai Wei does, he agrees with it and will not question it.

During this period, Cai Wei asked Li Ruzhou to find skilled craftsmen to create some glass utensils according to the drawings she drawn.

In recent years, although some glass products were imported from the West, there were no medical needles or the like.

She had to do it herself.

When everything was ready, ten days had passed, and there were still three days left before the day of Cai Wei's day.

At this time, the owner who promised to change the cornea also died of illness, and Li Ruzhou spent a lot of money to buy it.

On August 30, Cai Wei got up early in the morning and went to the Death Pavilion with Lu Ying.

She asked Li Ruzhou to prepare some ice cubes in advance and put them in a glass box with good sealing performance.

After the three of them met, she took the appliance to the cornea replacement house.

It is only half an hour before a person dies, and everything is still in time.

She wore a white coat, changed into homemade gloves, put on a mask, neatly removed the cornea, and then went to another house and took it in the same way.

The reason why she took two people was that she was afraid that if she didn't succeed, there would be room for repair.

So, the three of them went to Li Ruzhou's house non-stop.

In advance, Cai Wei had already prescribed a recipe for hemp boiling, and Li Rufan had already given it to Mrs. Li to drink.

The operating room is located in the bright room of Mrs. Li's bedroom, which is brighter.

At this moment, the light veil on the window was changed, and the curtain on the door was removed in order to make the room brighter.

Li Ruzhou even followed what Cai Wei said, removed all the cabinets and chairs in advance, and only placed a small bed near the door and surrounded a screen.

All the walls around are covered with glass mirrors imported from the West, and new bronze mirrors are hung on the caisson on the roof.

As soon as I entered the room, it was very bright.

Mrs. Li had already changed into homely cotton clothes and pants and was lying on the bed, and when Cai Wei came in, she was still awake.

Cai Wei bowed in front of her bed and said softly, "Old lady, this is the first time I have done this to change the cornea, and it may not be successful." ”

She only has theoretical knowledge, she was not an ophthalmologist in her previous life, but fortunately, she also saw people change their corneas back then.

This is also a duck on the shelf, right?

Mrs. Li glanced at her, and ordered her daughter-in-law Qi Shi, who was waiting on the side, to say, "Help the girl up." ”

Cai Wei stood up straight and looked at Mrs. Li, Mrs. Li sighed and said, "I have been buried in most of the earth, and I have enjoyed blessings in this life, and I have suffered a lot of sins, and my life is not in vain." I've been blind for more than ten years, and if it weren't for the girl, I wouldn't have any hope at all. How bad could it be? At best, he's blind. ”

When she said this, her consciousness was a little sluggish, and her speech gradually slowed down, and she only struggled to say, "If it's not good, I will never complain about the girl, and my son and daughter-in-law have no objections, just do it." And he closed his eyes, and fell asleep.

Cai Wei glanced at it, thinking that the numbness boiled and worked.

She pinched Mrs. Li's arm a few times, but there was no response, then she turned around and told Li Ruzhou and the others to wait outside, and called Lu Ying, "You come in and give me a hand." ”

Li Ruzhou really wanted to come in, but Cai Wei didn't call him, so he could only wait outside.

Lu Ying changed into a white coat outside the screen, put on a mask, washed her hands with strong salt water, put on gloves, and dressed exactly like Cai Wei, and then turned the screen and came in.

Cai Wei glanced at him, wrapped up and down like a mummy, and couldn't help but be happy.

The last time she was in the Death Pavilion, Lu Ying also helped her treat her legs, and this time she was also very familiar, Cai Wei swept over with a look, he knew what to use, and hurriedly handed it over, and by the way, he also helped Cai Wei wipe her forehead or something, so that Cai Wei could see the things in front of her in time.

Cai Wei first inhaled the extracted penicillin solution into the glass needle tube and gave Mrs. Li a skin test, and then used small tweezers to prop up her eyes and take out her cornea.

After that, the cleaning and disinfection stop the bleeding, and proceed step by step in an orderly manner.

Then, the frozen cornea was taken out and replaced with her.

He used needles and threads from the West to suture the wound, and finally wrapped her eyes with white yarn.

After all this, an hour has passed.

It is said that this operation will not take so long, just because Cai Wei is the first operation, so she can only take her time and not be careless in one step.

After wrapping it, Mrs. Li hadn't woken up yet, she looked at the results of the skin test, and she was not allergic, so she was relieved.

Except for penicillin, an antibiotic, she really doesn't know how to extract anything else.

The purity of this extracted penicillin is not very high, and it can only be used reluctantly.

She inhaled the prepared penicillin into the needle, injected Mrs. Li intravenously, and hung saline on her.

Lu Ying quickly cleaned up the used hemostatic cotton yarn and cotton swabs, put the utensils in a box, handed them to Li Ruzhou at the door, took them down and boiled them in boiling water for sterilization.

Cai Wei stayed in front of the bed, observing Mrs. Li's pulse.

After a while, she was relieved to see that there was nothing serious. called Li Ruzhou, Li Rufan and Qi, and instructed, "Let the old lady recuperate these days, and outsiders must not disturb her." The diet is light and mainly liquid. ”

Li Ruzhou's brothers agreed one by one, and Cai Wei said to Qi with a smile, "In the next few days, I will live in your house, and trouble my sister-in-law to prepare a quiet room for me next door to the old lady." ”

Qi hurriedly agreed, and hurriedly went to order.

Li Ruzhou was overjoyed, no matter what, Cai Wei cared so much about his mother, that is, she valued him.

Cai Wei turned around and asked Lu Ying again, "Don't go to the Death Pavilion these days, go home and live." ”

"No, I live here too." Lu Ying looked at Cai Wei stubbornly like a child.

Yes, everyone is commanded by the Jinyi guards, and if they want to live in a rich family like the Li family, how can they not welcome it?

Li Rufan and Qi didn't know Lu Ying's identity, so they glanced at him noncommittally and didn't say anything.

The person who came was a guest, and this person was unknown, but with Miss Mu, he couldn't be taken lightly.

Li Ruzhou knew Lu Ying's identity, although he did not show great enthusiasm, but he was also polite, "In this case, then come with me." ”

Lu Ying nodded.

Cai Wei doesn't care, anyway, his living here is no different from living at home. However, living in the Li family made her more steady, at least, the sick little white face didn't dare to beat her idea.

"Then, shopkeeper, I won't go to the Death Pavilion these days, and I'm guarding the old lady here." Cai Wei explained to Li Ruzhou again.

Of course, Li Ruzhou agreed, "Don't worry, there is a doctor there." ”

At the moment, the matter was settled, so Li Ruzhou arranged wine and dinner to entertain Cai Wei and Lu Ying. I picked two honest and capable servants to go to Lijia Village to report to Widow Mu.
