When Zhao Liang returned to the west courtyard, he did not see Wu Sanniang, and she had already left.

Jinjiang and Xiaoxiang didn’t know when Wu Sanniang left, only a letter left by the latter.

Zhao Liang opened it and saw that the letter had a simple line of words, which was a joint base.

There is nothing else.

There is no words between men and women, and there is no guarantee that Zhao Liang wants...

This made him feel very disappointed and a nervousness arose in his heart for a moment.

This is not because she is worried that Wu Sanniang will be in danger of falling into the hands of the government, but because she is worried that her secret will be revealed.

So Zhao Liang is really a super scumbag.

With a long sigh, Zhao Liang patted his butt and went to find his father.

It was his father and Liu Xuan who were responsible for the vaccination. After so long, it was time for the results to come.

It was about to be the 43rd year of Qianlong's reign, and Zhao Liang was going to give Heshen a New Year gift. This time, the cowpox was much awesome than the previous looms, Jenny machines and other things.

Even Qianlong would be overjoyed after seeing it.

Whoever asks these individuals to be afraid of smallpox?

Although the "human acne" technology has developed quite maturely at this time, human acne is not as good as cowpox. It is not rare for those who are weak to survive.

And cowpox is much safer than human acne.

Because this thing has been proven by facts in later generations, right?

Although the invention of vowelpox crushed the acne produced in China and completely lost its vitality, many people who don’t know much about it think that ‘human acne’ is optional and not worth mentioning.

How could they know that in the millennium before cowpox was invented by the British, "human acne" was the greatest and brilliant achievement in the history of smallpox virus treatment in the world.

Don’t think that smallpox is popular in China, but Europe is also suffering from it. It is said that in the 18th century, Europe could die as many as 500,000 people every year due to the smallpox virus.

This thing has become a common disease in Europe, especially in the UK.

When a person is adult, he must have contact with this disease, either because he has the ability to resist the disease, or he survives after getting sick and gains immunity.

John Cattle is a white colony overseas, and many wealthy families are unwilling to send their children to study in the UK. They would rather choose a low-level colonial education for their children than ask them to take the risk to go to the UK to experience what smallpox is.

Although there is smallpox circulating here, and I think about how the Spanish conquered the Inca Empire, the "smallpox" in the Americas is mainly a kind of epidemic.

Although it will sweep away some colonies every once in a while, causing many adults to get sick. But it is no more than in the UK, and you will hear it all the time.

Of course, the European continent is also shrouded in the shadow of the smallpox virus. Famous figures such as King William II of the Netherlands, Emperor Joseph of the Austrian, King Louis XV of France, and Emperor Peter II of the Russian Emperor were not spared.

In this case, the "human acne technique" originated in the Song Dynasty and matured in the Ming and Qing Dynasties was simply the great savior of the people of the world and the dawn of human beings to conquer the smallpox virus.

Even if about 2% of the recipients are infected, human acne is still the world's first "vaccine" that can effectively defend against smallpox.

In 1688, Russia sent a doctor to China to learn acne-bacterial surgery;

In 1744, Chinese doctor Li Renshan brought acne surgery to Nagasaki, Japan for the first time;

In 1721, Mrs. Montagu, the wife of the British Minister of Ottoman, brought the technique of vaccinating human acne from Ottoman to England and successfully tested it on her daughter.

By now, human acne has been widely circulated in Europe.

When Zhao Liang took out the cowpox at this time, it may not be abrupt for Europeans. After all, they have been crushed by Chinese medicine for so long. Now they are just being crushed again and again.

But in the eyes of the Qing royal family, this was definitely a great surprise.

Everyone knows that Kang Mazi has better smallpox. Some people with rich historical knowledge will also know that Duoduo also died of smallpox. They even know that among the eight sons and six daughters born in Shunzhi, there were about four princes, and five princes failed to live beyond the age of eight. The main cause of these princes' death was smallpox.

Also, if Emperor Shunzhi himself had not become a monk, he would have died at the hands of smallpox.

There is also Emperor Xianfeng, the husband of Empress Dowager Cixi, who not only fell off the horse's back and became a cripple, but also had an ugly face - comparable to his ancestor Kang Mazi. That's also because of smallpox.

Besides, his son Emperor Tongzhi, if he hadn't died of flower and willow disease, he would have died of smallpox.

From this you can feel the threat of smallpox to the Qing royal family. Naturally, the Qing Dynasty will attach great importance to smallpox and can also know how important cowpox is to their words.

Although this name is not good, it will even be ridiculed by many people at the first time.

Because it was more than 20 years later that when cowpox was invented in the UK, the inventor, Jenner, was treated unfairly. At a regular meeting of the Medical Society, Jenner told his long-thought-out ideas. But before Jenner finished speaking, the doctors who had always had a very good relationship with Jenner suddenly changed their friendly smiles and laughed at Jenner one by one and mocked Jenner. Some even said that people who had grown cowpox would grow cow hair on their bodies and horns on their heads.

Then there is no need to say much in China.

But does Zhao Liang need to worry about this?

No matter how ill-hearted Heshen was, he would not immediately send the news to Qianlong. He would definitely do some experiments first.

Some of the prisons of the Ministry of Justice are prisoners waiting to die as guinea pigs.

Dad Zhao was not in the East Courtyard. When he asked, he found out that he had gone to the market in the middle of the afternoon and had not come back yet.

As for what he was busy with in the market, it must be cowpox.

Dad Zhao never hides anything he does from Ma Zhao. Although Mom Zhao is just a scholar and has little knowledge, she also knows the meaning of cowpox.

"My son is capable. Our family has made a fortune since your great-grandfather's generation. After raising cows for so many years, no one has ever noticed that cowpox. If you do this this time, you will be the Buddha of the Wanjia."

"No, that's already done. Your father said that Dr. Liu's technique of acne is great now..."

Don’t have too much pride on Ma Zhao’s face.

Because this cowpox is much better than human acne. If it is promoted to the world, wouldn’t the acne Goddess be thrown behind the head in the future? Everyone worships her baby son?

Just think about this and Ma Zhao is so excited. How great virtue can this accumulate?
