Li Shimin is worthy of being a genius commander who has been in battle for a long time.

After he calmed down, he quickly thought about the use of gunpowder in warfare.

His thoughts are basically the same as Li Zhi's, and he also thinks that the deterrent effect of this thing is much greater than the killing effect.

When he explained his thoughts to everyone, the first person to understand was Li Jing, who was born as a military general.

I only heard Li Jing say: "With this thing, when our side fights on the battlefield, we can unexpectedly cause chaos to the enemy, and then we can easily destroy the enemy's formation." ”

Fang Xuanling and Wang Qi congratulated Li Shimin: "Congratulations to Your Majesty for obtaining this artifact, which has greatly increased the prestige of my Tang army." ”

Li Shimin smiled happily: "This is all the credit of the pheasant slave, if it weren't for him, I wouldn't have such a ability." ”

Fang Xuanling and the three of them hurriedly wanted to say hello to Li Zhi again.

Seeing this, Li Zhi hurriedly took the lead and said: "This thing can be made thanks to Doctor Sun's formula, Xiao Wang is just a little fine. ”

He didn't want to take this credit alone, after all, strictly speaking, Sun Simiao was only one step away from success.

If he snatches all the credit away at this time, it is likely to make Sun Simiao's heart unhappy.

Next, Li Zhi told him how he got the formula from Sun Simiao.

When everyone heard that Sun Simiao played a key role in it, they couldn't help but respect him a little more.

Li Zhi took the initiative to propose at this time: "Father, the son thinks that he should reward Doctor Sun, firstly, to commend him for inventing this thing, and secondly, to promote more people to work hard to study their own skills and create more divine artifacts for the Tang Dynasty." ”

After listening to Li Zhi's words, everyone nodded in agreement.

Li Shimin thought for a while and then asked Fang Xuanling and the others: "I plan to appoint Doctor Sun as a counselor, and the food is 600 stones, what do you think?" ”

Fang Xuanling said: "Now that Doctor Sun is setting up a medical school, since His Majesty wants to be rewarded, it is better to give him a real job by the way." ”

Fang Xuanling's opinion was agreed by Wang Qi and Li Jing.

The counselor is only a five-grade parasitic official, although he has an official position, he has no real power.

Now that Sun Simiao is in the process of establishing a medical school, it is a good time to take this opportunity to determine the status of the medical school.

Li Shimin asked with some hesitation: "What status do the three Aiqing think the medical school should be?" ”

Wang Qi thought for a while and said: "Now there are six schools under the name of Guozijian, all of which are a single category, and the minister thinks that the medical school should be under the jurisdiction of Guozijian, so it is better to be designated as a division?" ”

Datang's Guozijian is the highest educational management body, with both education and management functions.

Among them, the division is mainly responsible for the educational functions of various disciplines.

After listening to this suggestion, Li Shimin and others all agreed with it.

So in the end, it was decided to appoint Sun Simiao as the secretary of the Guozijian Division, mainly responsible for medical education, and at the same time to confer the title of doctor.

Li Zhi saw that Sun Simiao had been sealed as an official, so he stopped talking.

In his opinion, as long as it is not because of himself, Sun Simiao's future achievements will be erased.

As for other things, Li Zhi didn't dare to speak lightly now.

Being so enthusiastic about state affairs at a young age may not be a good thing in the eyes of others.

After the gunpowder matter came to an end, Li Zhi began to study refined salt and sugar.

In fact, Datang's salt-making technology is already quite good.

With the implementation of the five-step salt method, the salt of the Tang Dynasty no longer had any bitter taste.

It's just that the particles of salt are larger, and the purification is not thorough enough, so the color is not very white.

But these are just for the ordinary people of the Tang Dynasty.

The salt eaten by the princes and nobles of the Tang Dynasty will be filtered more thoroughly, not only the color has reached blue-white, but the particles are also very fine as in modern times.

What Li Zhi needs to do now is to improve the filtration process, so that the filtration process that used to take at least six or seven times has been reduced to one or two.

At this time, he used a mineral that Liu An found for him - limestone.

He didn't study this much when he was studying chemistry before.

He was well aware of the many uses of quicklime and hydrated lime.

During this time, Liu An has become his experimental assistant, and many times it is Liu An who helps him do some manual work.

Liu An had just smashed a piece of limestone into pieces, and was squatting to the side panting at this time.

While gasping, he asked Li Zhi suspiciously, "Your Highness, why did you let the minions break this stone?" ”

Li Zhi said: "According to the knowledge that this king learned from books, if you want to understand a mineral, you must first try to break it. ”

Liu An asked, "Then what else will His Highness do next?" ”

Li Zhi took a few pieces of gravel and looked at it for a long time, and then said, "Take it and burn it again." ”

After listening to his words, Liu An collected the gravel on the ground, and then carried it with a dustpan to the kiln where the coke was fired last time.

It was originally used to burn charcoal for the palace, but now it has been requisitioned by Li Zhi.

When he arrived here, Liu An was a little more relaxed, because all the workers here were left behind by Li Zhi.

They calcined the limestone at Li Zhi's request, and soon obtained some whitish stones.

Then Li Zhi had the stones broken up and turned into a pile of white powder.

Li Zhi left some of them and said that he would continue to study, and he had all the rest of them melted in a tank of water.

Soon the water in the tank began to boil, and a lot of white smoke came out.

Everyone looked at the scene in front of them in amazement, and they were all stunned by this phenomenon.

Next, Li Zhi divided the lime water and the plaster in it into many parts, and prepared to use them to continue other experiments.

He asked Liu An to write down each step, and then said to him: "This king has read many books, which mention many methods of the ancients to study all things, but no one has summarized them. ”

Liu An asked in surprise: "Your Highness, doesn't you want to sum up a set of methods for studying all things?" ”

Li Zhi nodded and said, "Although it may not be successful, this king wants to try." ”

The reason why Li Zhi is saying this now is to find an excuse for more and more experiments in the future.

Human development is a process of exploring the unknown, in which the unknown becomes the known and uses the known to solve problems.

If Datang's science and technology wants to develop, it must not rely on his own alone, what he has to do now is to show others a path of development.

Liu An didn't go as far as Li Zhi thought, he just felt that his little master had a very ambitious goal at the moment.

He opened his mouth and said to Li Zhi: "Your Highness can study the way of things deeply at such a young age, and the slave admires it. ”

Li Zhi waved his hand at him and said, "What is this?" It's just a matter of interest. ”
