Li Su forgot the purpose of coming here as soon as he entered the laboratory.

Curiously, he pulled Li Zhi to learn about all the devices here.

As Li Zhi explained, his eyes became brighter and brighter.

It was as if a magical door opened before his eyes.

He couldn't wait for Li Zhi to show him how to use these devices.

And after each experiment is completed, you have to try it carefully again.

In just one afternoon, he was already able to skillfully prepare three acids and two bases.

And he said nonsense to Li Zhi: When he saw a mineral he didn't know, he took it and burned it.

At this time, Li Su was completely immersed in the joy of success after success again and again.

Even forgot about the time outside.

It wasn't until Li Zhi repeatedly reminded him that it was not early, and he reluctantly left the laboratory.

Before leaving, Li Su hesitated and said to Li Zhi: "Ninth brother, can you still come here to play tomorrow?" ”

Li Zhi took the opportunity to say to Li Su: "Of course you can, but the younger brother's knowledge still has a lot of deficiencies, and he needs to study every day, so it is difficult to accompany the sixth brother more." ”

After listening to Li Zhi's words, Li Su said: "It's okay to do this, when I was experimenting just now, my brother also felt that many things were difficult to understand, why don't you and my brother study together from tomorrow?" ”

Li Zhi nodded with a smile and said, "I don't dare to invite if I want to, since the sixth brother has a word, the younger brother should obey it." ”

So unconsciously, a scumbag who didn't learn and didn't know how to do it was brought back into the classroom by Li Zhi.

Within a few days, this incident blew into the ears of Li Shimin and the concubines like a gust of wind.

Everyone was shocked by the news that Li Su was studying seriously.

No one could have thought that just a few days ago, Li Zhi sued Li Su in front of the emperor.

Now the two are actually working together in their studies again.

Li Shimin naturally laughed happily when he heard the news.

Nothing makes him happier than the sudden change of his son, whom he thought was unsuccessful.

Yang Shufei cried with joy when she heard the news.

She knew that her son was suddenly sensible, and Li Zhi's credit must be indispensable.

Perhaps everyone's shock is not as good as the current Li Zhi.

He discovered that Li Su was a genius in science.

Li Su was not only able to quickly understand the knowledge of arithmetic in Taixue, but even the modern mathematical knowledge compiled by Li Zhi himself could be learned at once.

This is the first time that Li Zhi has discovered a science genius like him in this era.

He even doubted that if Li Su could live with him in modern times, then Li Su would probably surpass him in his achievements in science.

Li Su is not only smart, but also has strong hands-on ability.

When the two were doing hands-on experiments, Li Su basically did not make mistakes.

With this discovery, Li Zhi immediately decided to sort out the mathematics, physics and chemistry knowledge he had learned as soon as possible and teach it all to Li Zhi in one go.

The reason why Li Zhi was so urgent was because he found that he was simply too busy right now.

Not only did he have to study, but he also had to learn medical skills from famous doctors such as Sun Huipu and Sun Simiao.

In addition, he had to follow Li Jing to learn the art of war, and he had to pay attention to the training of the new army at any time.

He urgently needed some right-hand men to help him promote the development of Datang's science and technology.

And Li Su can definitely be regarded as an extremely rare talent.

This guy is a bit of a tendon, and he can do research on the things he likes.

Especially when Li Zhi moved back a microscope from the Shaofu Prison, he was even more immersed in the microscopic world and couldn't extricate himself.

In contrast, Li Zhi has to take care of more.

When he succeeded in building the telescope and microscope, he first moved one back to his laboratory and then gave the other two to the medical school.

When Sun Simiao and other famous doctors observed bacteria through microscopes, their medical realm was destined to enter another level.

They decided to use a microscope to re-prove their medical theories, and even more so to re-validate the prescriptions they were familiar with.

In addition, Li Zhi also proposed the concept of surgery to them, and even came up with a method of preparing alcohol for them to use for disinfection.

When Li Zhi handed over the telescope to Li Jing, this veteran who had been fighting for many years simply shattered his three views.

He trembled and stood on the lookout in the barracks with the telescope in his hand.

At this time, in his line of sight, he could clearly see a village dozens of miles away.

The most amazing thing is that he can clearly see the movement of the villagers.

The veteran knows exactly what this thing can do to the battlefield.

He even thought of several uses for telescopes in an instant.

After Li Jing came down from the high platform, he said to Li Zhi excitedly: "Your Highness, with this thing, my army of the Tang Dynasty is enough to be invincible. ”

Li Zhi said: "The teacher's words are wrong, although this thing is wonderful, it also needs to be matched with famous generals, and it is difficult for ordinary generals to have such an opinion as a teacher." ”

After listening to Li Zhi's words, Li Jing thought about it seriously and felt that Li Zhi was a little conservative.

However, he did not argue with Li Zhi anymore, but said with a little excitement: "This thing is very compatible with the tactics of the new army, and it will definitely work wonders on the battlefield as long as you are more familiar with it." ”

Li Zhidao: "The students thought that sharing this object with the sand table might play a greater role. ”

Li Jing nodded after hearing this.

He said with a thoughtful expression: "That's true, it's just that the sand table is not easy to make, and you still need to have certain skills." ”

Li Zhi said: "The students will have people make a simple sand table as soon as possible for the march, and as for how to survey the terrain and draw a map, they still need to be taught by their teachers." ”

Li Jing nodded and said: "The old man is responsible for this matter, please rest assured Your Highness." ”

Although there were also high-ranking generals like Li Jing in this era who knew how to use the sand table to deploy operations, the specific methods were not popular.

Li Zhi felt that this was a serious waste of resources.

You must know that even in modern warfare, wargaming is still an extremely effective way to prepare for war.

Although it can be difficult for people nowadays to learn to draw military maps and then translate them into accurate sandboxes.

But in Li Zhi's view, this is a completely overcomeable difficulty.

The basic material for making the sand table is some fine sand, which can be wet with water when used.

Li Zhi also found some sawdust, soil and other materials to distinguish different landforms such as mountains and hills.

There are also strips of cloth representing rivers, various cards, signs, and so on.

After two days of production, Li Zhi led people to move the sand table to the barracks.

The sand table made by Li Zhi is much more exquisite than the previous one made by Li Jing by relying on local materials.

Therefore, Li Jing felt very satisfied after seeing it.

So since then, the training subjects of the Dragoon have added sand table making and wargame deduction.
