As soon as the pharmacy business was good, there were more people staring at her.

In the past, she could leave if she wanted to go, and she could stay if she wanted to, but now how many pairs of eyes are staring at her.

Even the strong man who pulled the yellow croaker cart at the door knew her, and every time he saw her come out of the pharmacy, he diligently pulled the cart forward:

"Doctor Xu, do you want to take the car?"

"Doctor Xu, where are you, I'll send you!"

“……”

The patrol police at the city gate also recognized her, and when they saw her go out of the city, they greeted her with a smile:

"Doctor Xu, out of the city?"

"Doctor Xu, this is going to inspect the pharmaceutical factory, right? Is it almost covered? ”

"Why is Dr. Xu walking? I'll call you a rickshaw! ”

Xu Yin: "......"

Thank you!

Thanks to the time when the fake medicine warehouse was burned, not so many people knew her, otherwise she was afraid that she would have to change the map to break the dungeon.

Xu Yin had a headache, wondering if she should prepare another outfit and change her face when she went out? Is she still able to keep a secret? Public figures have no privacy!

On this day, she stayed at the construction site of the pharmaceutical factory that was about to be completed until dark, the workers finished work and went home, and Xiao Wu was also driven back to the city by her to accompany his grandfather, so she changed into night clothes and walked all the way back to the pharmacist in the moonlight.

On the way, she suddenly thought of an idea: the medicine hermitage, the pharmacy outside the city, and the pharmacy in the city, these three points are a triangle, and she can dig three tunnels to connect these three places, so she doesn't have to go out with everyone's hot eyes, and she can come and go unhindered in the tunnels.

If you change people, you will think this is whimsical, right? Relying on one hand to dig through three tunnels, the shortest is seven or eight kilometers, and the longest is nearly 20 kilometers, which is too huge.

But she has a construction robot that can not only dig tunnels, but also design tunnels into earthquake-proof, collapse-proof, and leak-proof air-raid shelters, which is completely feasible!

One is not enough to redeem another one, and it is not impossible to start construction of three tunnels at the same time.

Just do it!

That night, Xu Yin first found a hidden entrance in her room, just under the bed.

The bed she slept on was made of pure mahogany, and ordinary people couldn't move it even if they moved it, let alone carrying it.

Xu Yin moved the bed out of the way and pried up the large stone slab in the middle under the bed, intending to set the entrance and exit of the pharmacist hermitage here.

Then release the construction robot, set the appropriate depth, width, and locate to the target location, and let it start.

The robot excavated day and night, and the dug mud was stored in the system warehouse by Xu Yin one by one, and another day he found a way to pull it back to the Yakushi Nunnery to fill in the soil and plant trees.

The tireless robot dug under the pharmacy in two days and under the pharmacy in three days, and the entrances and exits of these two places were set up in the owner's lounge.

Xu Yin's lounge in the pharmacy was originally arranged upstairs, but it has been adjusted in the past few days and moved downstairs, next to the medicine warehouse.

"Something strange happened recently!"

On this day, as soon as she came out of the lounge, she heard the waiting patients chattering to each other:

"My dog used to bark only when strangers passed by my door, I don't know what happened these days, it barked from time to time, even during the day, it barked at night, and I didn't sleep well for a few days."

"Your dog barks too? It's the same in my family, and my man also said that he was in heat, which upset people. ”

"You say, will there be that ......?"

"Which one?"

"That's it, what month did you forget?"

"Isn't this month July? What happened in July? ”

"July 15, the ghost door is open! We can't see it, but cats and dogs can! ”

"Oops! It's true that my dog started barking in July. ”

"Yes, yes, yes! Around fifteen, I screamed the most! ”

"Oh my god! I'm getting goosebumps! ”

"Me too!"

Xu Yin: Me too!

I was stirred up by your brains.

However, fortunately, several sections of tunnels in the city have been dug through, and the next digging is outside the city, otherwise with the acuity of cats and dogs, not only running and barking, but also staring at the ground from time to time and barking, arousing the suspicion of the handsome, sending people to dig three feet into the ground, is it not over?

After spending seven and a half months without danger, the three tunnels were completed, and she finally ended the troublesome routine of finding excuses to get in and out of the city every day.

Put a needle-eye communicator on the back of the door, and if someone knocks on the door, the wrench will vibrate the receiver, and you can immediately gallop through the unobstructed tunnel without going out.

After the construction robot dug three tunnels, Xu Yin did not put them away, but continued to dig.

However, the next digging is a fork in the road to cover up, basically outside the city, and the cats and dogs in the city have finally stopped.

There are several forks in the road, some are wide, some are narrow, some are narrow, some are a narrow slit at the exit, and some are a mouse hole, but they are equipped with a thin eye net, and even rats can't get in. Traps and traps were also laid along the way, and only she knew how to crack them.

There is a ventilation eye for the fork in the road, and although the fresh air system cannot be installed in the tunnel, the air is still circulating.

Every time Xu Yin enters, she will take a sprayer filled with Linghu water, and spray it along the way, containing spiritual energy, and the authentic air is fresher.

With the best way to commute, Xu Yinren did not go out at the Yaoshi Nunnery, and took the nuns to practice boxing, farming, and collecting mushrooms in the morning; In the afternoon, I rested in my room, but in fact I went to the pharmacy for a consultation; In the evening, I returned to the medicine nunnery to teach nuns to distinguish herbs, learn pharmacology, and make some commonly used medicinal powders and ointments. I saved more money and took it to the pharmacy to sell on the consignment, and the money I got from the sale was exchanged for cloth and grain and oil to bring back.

The pharmaceutical factory was completed, and a batch of pharmaceutical equipment that she pretended to have transported from the capital also arrived.

She expanded from two points to one line to three points and one line, compressed the consultation time to two hours in the afternoon, and then went to the pharmaceutical factory to see the progress of the clinical trial that Comrade Xiao Wu did with mice.

There are two new drugs: one is independently developed by Xiao Wu, which can flatify sulfonamide, and the other is penicillin that Xu Yin came out with Xiao Wu's hands.

She once read a research topic about the need for skin tests for penicillin in China and the big countries in Europe and the United States, and it was only then that she learned that the so-called penicillin allergy is not actually allergic to penicillin itself, but caused by insufficient purity and too many impurities.

Among these impurities, there is a main component called penicillium thiazole molecule, which will combine with proteins after entering the human body to form penicillium thiazole protein, which is a strong allergen.

However, if you want to improve purity, you will have to increase the cost. In real history, the early penicillin in China relied on imports, and the purchase price was too high for the people to use, so they had to choose low-cost but low-purity penicillin, which must be tested before use.

This time, she wants to purify the highest purity penicillin, so that domestic compatriots can use penicillin that is cheap and high-quality, and does not require skin testing.

In the same way, the export of foreign exchange depends on this medicine to earn!
