Chapter 1168: The Romantic Girl Paired with Farming in the Republic of China (19)

 Once the business of the pharmacy is good, more and more people will stare at her.

 In the past, she could leave whenever she wanted and stay whenever she wanted, but now so many pairs of eyes were staring at her.

Even the strong man pulling the yellow croaker cart at the door knew her. Every time he saw her coming out of the pharmacy, he would diligently pull the cart forward:

“Doctor Xu, would you like to take a car?”

“Doctor Xu, where are you going? I’ll take you there!”

　　　…”

The patrol police at the city gate also recognized her. When he saw her leaving the city, he greeted her with a smile:

“Doctor Xu, are you leaving the city?”

“Doctor Xu, are you going to inspect the pharmaceutical factory? Is it almost finished?”

“Why are you walking, Doctor Xu? I’ll call you a rickshaw!”

 Xu Yin: “…”

 I thank you!

When the fake medicine warehouse was burned down, not so many people knew her, otherwise she would probably have to change the map to enter the dungeon.

Xu Yin had a headache. She was wondering if she should prepare another outfit and change her face when she went out. Still like this, can she still keep the 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 their work and went home. Xiao Wu was also driven back to the city to accompany his grandfather. Then she changed into night clothes and walked under the moonlight. Quickly return to Yakushi'an.

On the way, she suddenly came up with an idea: Yaoshi'an, a pharmaceutical factory outside the city, and a pharmacy inside the city. These three points formed a triangle. She could dig three tunnels to connect these three places, and she would not have to face the burning eyes of everyone. After you go out, you can go back and forth unimpeded in the tunnel.

 For another person, you would think this is whimsical, right? To dig through three tunnels with one hand, the shortest is seven or eight kilometers, and the longest is nearly twenty kilometers. The amount of work is too huge.

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

 If one tunnel is not enough, then another one will be replaced. 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 to her room, just under the bed.

The bed she slept on was made of pure mahogany. Most people couldn't move it, let alone carry it.

Xu Yin moved the bed and lifted up the big stone slab in the middle under the bed, intending to locate the tunnel entrance and exit of Yaoshi'an here.

 Then release the construction robot, set the appropriate depth, width, and position it at the target location, and let it start work.

The robot excavated day and night, and Xu Yin collected the excavated mud in piles in the system warehouse. She would find a way to bring it back to Yaoshi'an another day to fill the soil and plant trees.

The tireless robot dug under the pharmaceutical factory in two days and under the pharmacy in three days. The entrances and exits of these two places are located in the owner's lounge.

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

 “Something weird happened again recently!”

On this day, as soon as she came out of the lounge, she heard the patients waiting for treatment chatting with 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, and also barked at night. It was so noisy that I couldn't sleep well for several days. "

“Your dog also barks randomly? Mine does too, and my husband even says it’s in heat, and the barking makes people upset.”

"You think, is there that one..." "Which one?"

“That’s it. Which month this month have you forgotten?”

“Isn’t this month July? What happened to July?”

“The door to **** opens on July 15th! We humans can’t see it, but cats and dogs can!”

“Oh! It’s true, my dog ​​started barking in July.”

 “Yes, yes, yes! The loudest shouting occurs around the age of fifteen!”

 “Oh my God! I’m getting goosebumps!”

"Me too!"

 Xu Yin: Me too!

 I was inspired by your imagination.

However, fortunately, several sections of tunnels in the city have been dug, and the next ones will be dug outside the city. Otherwise, with the acumen of cats and dogs, they would not only run around and bark, but also stare at the ground and bark from time to time, which made the commander suspicious and sent him People have dug three feet into the ground and it’s not over yet?

Having passed the middle of July without any danger, the three tunnels were completed, and she finally ended the troublesome daily routine of finding excuses to go in and out of the city every day.

Attach a needle-eye communicator on the back of the door. Once someone knocks on the door, the finger-toggle-like receiver will vibrate, and you can rush through the unobstructed tunnel without leaving the house.

 After the construction robot dug three tunnels, Xu Yin did not put them away and continued digging.

However, all the branch roads dug next were for cover, mostly outside the city. The cats and dogs in the city finally stopped.

There are several branch roads designed, some are wide, some are narrow, some exits are just a narrow gap, and some are mouse holes, but they are equipped with fine-mesh nets so even mice can't get in. Traps and traps have been set up along the way, and only she knows how to crack them.

 There are ventilation holes with bifurcated passages. Although a fresh air system cannot be installed in the tunnel, the air is still circulated.

Every time Xu Yin goes in, she will take a sprayer filled with Linghu water and spray it along the way. It contains spiritual energy and makes the authentic air fresher.

With the best way to commute, Xu Yinren did not go out at Yaoshi'an. In the morning, she took the female nuns to practice boxing, farm, and collect mushrooms. In the afternoon, she pretended to rest in her room, but actually went to the medicine shop for consultation. In the evening, she returned to Yaoshi'an to teach the female nuns. Identify herbal medicine, learn pharmacology, and make some commonly used medicinal powders and ointments. If you save too much, take it to the pharmacy to sell it on consignment. The money you get from the sale is exchanged for cloth, grain and oil and you bring it back.

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

 She expanded from two o'clock and one line to three o'clock and one line, and shortened the consultation time to two hours in the afternoon. Then she went to the pharmaceutical factory to see the progress of Comrade Xiao Wu's clinical trials on mice.

There are two new drugs: one was independently developed by Xiao Wu, which can treat sulfonamide, and the other is penicillin, which was developed by Xu Yin through Xiao Wu.

She once read a research topic about the fact that skin tests for penicillin are required in China but are not required in European and American countries. It was then that she learned that the so-called penicillin allergy is not actually caused by penicillin itself, but by insufficient purity and too many impurities. of.

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

 However, if the purity is to be improved, the cost will inevitably increase. Historically, all early domestic penicillins were imported, and the purchase price was too high for ordinary people to afford, so they had no choice but to choose low-cost but low-purity penicillin, which required a skin test before use.

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

 Similarly, export foreign exchange can be earned by relying on this medicine!
