Datang: Time travel in two months, wait online, hurry up!

This reassured him a lot.

As for boys and girls?

He really doesn't care.

In modern times, it is because the number of children that can be born is limited. In the early years, there was only one child, and at most there was a second child. Naturally, I hope it will be a boy.

But in Datang, first of all, he had a wife and a concubine, and there was no such thing as limiting the number of children.

So, he doesn't have to worry about it at all, as both sons and daughters will have them.

He didn't care about it, but this news was bad news for Kinderman and Jin Shengman.

Although it is quite metaphysical, but this era believes in metaphysics.

Since the two heard the news, their appetites have decreased for a few days.

Regarding this, Li Ke could only shake his head and smile, there was nothing he could do.

In his spare time, when he was alone, he couldn't help but look in the direction of Chang'an City.

Because he received news from intelligence personnel, Li Chengqian, Changsun Wuji and others seemed to be active recently.

Although there is no evidence that they have a tendency to rebel, Li Ke knows very well that they have already begun preparations.

"Old fox, have you jumped into the pit this time?"

After Li Ke heard that Changsun Wuji and others also participated, a happy smile appeared on his face.

It's really inconvenient for him to deal with Changsun Wuji, especially when Li Shimin is still around.

After all, he is Empress Changsun's elder brother and Li Shimin's eldest uncle, so it is quite troublesome to do anything to Changsun Wuji.

However, if Changsun Wuji wanted to die by himself, then there would be no such worries.

Historically, Changsun Wuji did not participate in Li Chengqian's rebellion case, but chose Li Zhi as a new supporter early on.

But this time, before Li Zhi grew up, Li Ke became the next emperor appointed by Li Shimin.

In addition, Li Ke deliberately targeted Changsun Wuji and his faction.

It seems that he has an attitude of not giving Changsun Wuji and others a chance to survive.

He chose to rebel with Li Chengqian just to force Changsun Wuji to the point of being unbearable.

Judging from the information received now, his plan has been successful.

Changsun Wuji really participated in Li Chengqian's treason case!

"Since you dare to rebel, then even if it's Father, you won't show any sympathy!"

Li Ke smiled, Changsun Wuji's end was basically doomed.

Li Ke was in a very good mood when he thought that Changsun Wuji, the old Yinbi, would soon be completely finished.

However, he also knew that he might be going to Chang'an City in the near future.

Because if Li Chengqian rebelled, the position of prince would definitely be lost, even if Empress Changsun was resurrected from Zhaoling!

Now that Li Chengqian's crown prince is gone, who else can he give this crown prince to besides him?

At this time, a person came outside and came to report the news with a full face of excitement.

"His Royal Highness, the 'penicillin' you mentioned has been successfully extracted!"

As soon as the man saw Li Ke, he couldn't help telling Li Ke the news excitedly.

"Oh?"

Hearing this, Li Ke's eyes lit up immediately, and the smile on his face became even more intense!

It's really good things come in pairs!

He arranged for people to study penicillin a long time ago.

In order to provide research equipment, he asked the glass workshop to prepare special lenses, and then made a microscope.

As for the talents who study biology, they are still those Taoist priests.

They like to make longevity medicine, so Li Ke also thought of their professional counterparts, so he arranged for them to study biological knowledge.

Li Ke told them directly that the elixir of longevity cannot be refined in an alchemy furnace, and if they want to obtain the elixir of longevity, they can only find the answer in biology.

And those Taoist priests' pursuit of longevity medicine also exceeded Li Ke's expectations, whether they used an alchemy furnace or found it from biology.

Anyway, since Li Ke said it, they started to study biology.

After they studied biology for a period of time, Li Ke told them that there is a drug called penicillin, which can cure diseases and save lives.

In this era of extremely backward medical conditions, a cold and fever may kill a person.

Not to mention wound infections and some diseases.

But if you have penicillin, you can use penicillin to treat it very well.

Penicillin is an important antibiotic with high efficiency, low toxicity and wide clinical application.

The emergence of penicillin greatly enhanced the ability of humans to resist bacterial infections.

Moreover, the appearance of penicillin directly increased the average life expectancy of people at that time by 15 years!

Looking at it from another angle, this can be regarded as having a little something to do with longevity medicine, right?

After all, a person who was about to die from the disease recovered after using penicillin and survived in good health.

Isn't this the edge with some longevity medicine?

Moreover, the emergence of penicillin has also provided a great guarantee for the life and health of himself and his family.

Even if you are sick in the future, with penicillin, at least the chances of being cured will be much higher.

"Go, go and see!"

Li Ke was very happy, leaving the Metropolitan Governor's Mansion with eyes full of anticipation, and walked towards the biology research room.

PS: Fourth more! .

Chapter 344 Clinical Experiment of Penicillin!The first merchant ship is back!

This edict in the newspaper is tantamount to dropping a blockbuster in Yangzhou and Suzhou.

It directly and completely changed the cognition and thinking of everyone in Yangzhou and Suzhou.

Although Li Ke was the guarantee before, everyone recognized these three new disciplines very much.

But I still feel a little worried about the future of these three new subjects, and I still feel that it is safer to study the Four Books and Five Classics.

After all, to learn new subjects is to work in Yangzhou at most, but if you study the Four Books and Five Classics, if you take the high school imperial examination, you may become a bachelor of Hongwenguan later!

If he could become a great Confucianist like Kong Yingda, he would be famous in history.

But after the content of this edict was exposed, everyone's thinking was completely changed.

Because these three new subjects have also been added to the imperial examination subjects, if you don't study hard, you will not be as good as others in the imperial examination in the future.

If you study well, you can lead others in the imperial examinations, get better grades, and get higher rankings.

Therefore, in the future, they will definitely supervise their children strictly and study three new subjects seriously.

Moreover, the concepts of Science Museum and Engineering Museum proposed in the imperial decree, as well as the status and treatment of Bachelor of Science Museum and Bachelor of Engineering Museum, shocked everyone even more.

Since learning these three new subjects can also become a bachelor-level figure and leave a name in history, it is natural to study it seriously!

Besides, Yangzhou and Suzhou are the first places to learn these three new disciplines, and they will have a first-mover advantage in the future, and the probability of making outstanding contributions will be higher.

It can be said that it is much less difficult for their children to become bachelors of Science Museum and Engineering Museum than Hongwen Museum!

Everyone will still settle accounts in their hearts. Soon, even if they understand which one is more promising, they will naturally have a decision in their hearts.

So, in the next period of time, Li Ke received the news from below.

It is said that it is 21 days in various government schools, everyone's enthusiasm for learning the three new subjects is unprecedentedly high, and everyone is studying very seriously.

Upon receiving this news, Li Ke couldn't help laughing.

Enthusiasm is high, he hopes that everyone's enthusiasm for learning will become higher and higher, so that more talents can be cultivated as soon as possible.

Next, time passed quickly.

Nearly three months have passed since the first batch of merchants went out to sea.

Li Ke calculated the time, and it was almost time to come back.

During this period of time, Li Chunfeng and Yuan Tiangang had drawn a complete line of longitude and latitude with Zhuque Street in Chang'an City as the prime meridian, and standardized the latitude and longitude.

And under Li Ke's guidance, they also successfully developed a sextant.

After that, use the sextant to calculate through the observed data, and then get a latitude and longitude, and verify it on the map.

After a lot of tests and calculations, they improved the sextant even more.

The coordinates determined by the sextant and the map are becoming more and more accurate. Although the accuracy is far behind modern satellite positioning, it is at least within a range.

In the vast sea, as long as you can know a rough range, it is already a great help!

So, the latitude and longitude lines and sextant are complete.

After three months of construction, the Navigation Academy is basically completed and ready to be put into use.

After all, after the blueprints are released, there are a large number of workers in Shanghai City, and the college can be built in a very short period of time.

"Yuan Tiangang and Li Chunfeng went to Hainan Airlines Academy as lecturers, mainly teaching students how to use the sextant and how to calculate latitude and longitude!"

Li Ke made arrangements for Yuan Tiangang and Li Chunfeng.

"Yes, Your Highness!"

Yuan Tiangang and Li Chunfeng were also quite excited.

During this period of time, they used the sextant many times to determine their latitude and longitude in many places, and looked for the corresponding latitude and longitude on the map.

In the end, they found that their location was almost the same as the latitude and longitude on the map. This discovery made them very excited!

Because this is a great advance in astronomy and geography!

Now, more people can be taught to use sextant and latitude and longitude, which is undoubtedly a promotion of astronomy and geography.

The two of them are still very excited about this task.

There are lecturers in navigation, there are lecturers in position identification, and the construction of the Nautical Academy has been completed.

Everything is ready, just recruiting students.

Recruiting students is also simple.

As long as the first batch of merchants who went to sea came back and the demand for captains and seamen in the entire market suddenly increased, there would naturally be a large number of people who wanted to study at the Nautical Academy.

At that time, publicize a little in the newspapers, such as how high the salaries of the captain and seafarers are, how big the talent gap is, and so on.

It is guaranteed that there will be an endless stream of people signing up for the Nautical Academy!

And this time is coming soon.

Li Ke first asked the Nautical Academy to start preparing for enrollment, as well as some follow-up preparations.

He spends leisurely time with his family at home.

Now, the bellies of Kinderman and Jin Shengman have grown obviously.

After all, I have been pregnant for nearly six months, and I will give birth in about four months.

Since this is Li Ke's first and second child, the two are already the focus of the family's care.

All kinds of nutritious things are prepared for the two of them every day.

And as the belly got bigger and bigger, Li Ke also saw the brilliance of motherhood in the two.

Even Jin Shengman, who is quite lively, seems to have matured a lot, and there is a hint of maternal love in his eyes.

In this regard, Li Ke considered that the current production environment is very worrying, so he specially set up an obstetrics and gynecology department, which is full of female doctors.

He personally explained to these female doctors the medical knowledge related to obstetrics and gynecology, some points that need attention, and so on.

After all, he will not only have these two children in the future, but will have more children in the future.

In ancient times, giving birth was very dangerous. Once something went wrong, it was likely to be a tragedy of two lives.
