Datang: I was exposed by Princess Changle

When Lin Xuan heard this, he was so ashamed!

After returning home, Lin Xuan was furious, and scolded Gongsun Xin severely.

Correct!

Do not eat lo mei for three days!

Introspect!

Fortunately, the matter has come to an end.

The lo mei pervading in Lantian County faded a bit, but then there was a smell of roast duck.

The scent of hundreds of chickens and ducks even wafted into the Chang'an City Palace.

The county magistrate Xie Tong is an old boy who also does business. Want roast duck or chicken?

Get chicken wings and duck wings instead!

Lin Xuan was too lazy to care about this.

-

At this time, Lin Xuan devoted himself to his industrial plan.

However, he had too many choices.

Originally, Lin Xuan chose at the beginning to build highways across the country and build canals to develop water transportation.

By the way, looking forward to the future, he plans to connect all Datang with electricity, set up factories, open banks, and develop walkie-talkies.

Because these are also simple, with the help of the system, even if the productivity of Datang is low now, it can still be done.

At that time, he will become an industrial tycoon in minutes, and the richest man in the world is just around the corner.

However, he suddenly received a letter from Feige, which made Lin Xuan change his mind.

That is, a plague broke out in Guanzhong!

Flying Eagle reports that there are countless refugees around Chang'an City recently!

But they were all intercepted outside Chang'an City.

Because it is uncertain whether these refugees carried the plague.

So Lin Xuan decided to make medicine!

Like Datang: I was exposed by Princess Changle, please bookmark it: () Datang: I was exposed by Princess Changle, and the update speed is the fastest.

Chapter 255 Vaccine!

Become the largest pharmaceutical manufacturer in Datang!

As small as a cold and a scratch!

From terminal illness to plague, everything will be Lin Xuan's business scope from now on.

There is actually a reason for Lin Xuan to do this.

Human beings are always the most afraid of death, and they spend the most and the fastest money on various diseases and various treatments.

So Lin Xuan chose pharmaceuticals.

Facing most of the diseases in ancient times, he only needs to search the system to get the solutions directly.

At this time, the first medicine that Lin Xuan wanted to produce was the specific medicine for smallpox.

Smallpox is a severe infectious disease, once infected, the fatality rate is extremely high.

In ancient times, once infected with this kind of plague, it would be fatal.

In the prevention of smallpox, smallpox infection can be prevented by vaccination with vaccinia, and the effect is excellent.

Because the vaccinia virus and the smallpox virus are very similar, they have the same antigens.

However, the toxicity of vaccinia is relatively small, and only mild discomfort will occur after infection.

However, resistance against the vaccinia virus can be developed.

The vaccinia vaccine is an inactivated virus.

After being inoculated into the human body, it will produce an immunity against the smallpox virus.

Therefore, after vaccination with vaccinia, it will not cause human-to-human transmission and can prevent smallpox.

But cowpox is always a virus in cattle, so how could it be so easy to spread?

And using the advanced extraction technology of later generations, the bacteria in vaccinia can be eliminated.

Then, the mass production of drugs can easily solve the threat of smallpox.

Lin Xuan didn't expect to make much money this time either.

But if this time he can gain the reputation of Huimin Pharmacy, it will be very important to his future development.

"Let me look for it."

Lin Xuan was talking to himself.

Then search in the system: How to make smallpox special medicine easily?

After 1 minute, it was actually searched out, and the system is really powerful!

But all this is because of the progress of the times.

The progress of modern times in later generations is changing with each passing day.

The technology of ten years ago was a secret that was not passed on ten years ago, and it would not be spread casually.

But if ten years later, it will become an outdated technology of the bad street.

This simple method of making smallpox special medicine is like this.

Lin Xuan took a closer look, and found that cows were still needed, and they were cows infected with cowpox.

But you don’t need a lot of heads, you just need to use vaccinia as a vaccine to cultivate, and finally produce a smallpox specific medicine in batches.

The detailed steps seem to be very simple, nothing more than adding some herbs and burning potions at special temperatures.
