Li Su had no idea what a meaningful thing he was doing now.

He just reads the mathematics, physics and chemistry books compiled by Li Zhi every day, and then conducts experiments according to the ideas and research directions put forward in the books.

And Li Zhi has already begun to consider finding him a few poor children of the same age, so that he can bring apprentices for him.

If one day Li Su knew that Li Zhi had been using him since he was so young, he didn't know what his reaction would be.

Since they did not have the ability to produce a large amount of pure oxygen, Li Zhi and his team could only rely on increasing the smelting time to ensure that all the mixed elements were dissolved, so the experiment was quite difficult.

But they were patient.

Li Zhi took this opportunity to make up for some blind spots in knowledge.

Li Su is completely immersed in the exploration of the unknown, unable to extricate himself.

As for Bakken, he has been fooled by the characteristics of stainless steel mentioned by Li Zhi, and he can't find the north.

As long as he can see the finished stainless steel product with his own eyes, he is willing to put in more energy.

Time passed quietly.

It wasn't until more than a month later that they finally got the proportions of various raw materials roughly right and made the first furnace of molten steel.

Several successive hydraulic presses have pressed the steel sheets into shapes and immediately split them into black sheets.

With the pickling complete, the steel plate is heated again.

It is then continuously rolled into a stainless steel plate with a smooth and shiny surface.

Li Zhi and the three craftsmen present all looked at the steel plates in front of them and showed their fascination.

Bakken's hand stroked the steel plate gently like a baby.

He muttered in his mouth, "Is this the stainless steel in His Highness's mouth?" You can use it directly to make a blade. ”

Li Zhi said with some embarrassment: "That... The properties of this steel are not yet very clear, and the specific uses have yet to be explored. ”

At this time, Li Zhi's heart was indeed not sure.

After all, the steel he used in his previous life was a finished product purchased in the market.

Although the approximate content of various elements is marked, he cannot guarantee the specific accuracy.

Therefore, they had to carry out a series of experiments to be able to accurately determine the direction in which the steel was suitable.

But this is already a relatively big success.

At least in the future, other types of steel can be developed in this way.

Li Su quietly admired it for a while, and then lost interest in these stainless steels.

He opened his mouth and asked Li Zhi, "What else does this king need to do next?" ”

Li Zhi blinked his eyes for a long time before he spoke: "Sixth brother, it's better to take some students to continue analyzing substances!" ”

Li Su frowned and said, "It's okay to analyze the substance, but why does the ninth brother want this king to take the students?" ”

Li Zhi flickered: "Sixth brother, do you think, there are so many substances in the world, how can you fully understand it with only the sixth brother alone?" ”

Speaking of this, he stepped on his foot and hooked Li Su's arm and continued: "If Sixth Brother can cultivate a group of outstanding students, won't he soon be able to understand more?" ”

Li Su frowned and pondered.

He felt that Li Zhi had some truth in what he said, but he also felt that something seemed wrong with this matter.

He felt that he was not yet capable of teaching his students, and it seemed that this matter should be the responsibility of Li Zhi.

So he opened his mouth and said to Li Zhi: "Brother Wei thinks that the matter of teaching students should be done by you, Ninth Brother, and Brother Wei's knowledge is still lacking. ”

As soon as Li Zhi heard this, he immediately became anxious.

Are you kidding?

Let him teach a bunch of children who don't even know words to learn mathematics, physics and chemistry from scratch, then he must not be exhausted to death?

So he continued to persuade: "Sixth brother must not be arrogant, with your intelligence and intelligence, I believe that it is enough to strengthen yourself and teach students at the same time. ”

Li Su said: "Those scholars have always been arrogant, they may not be able to accept the teachings of their brothers, right?" ”

Li Zhi said: "Since the sixth brother is worried about this, the younger brother will recruit a group of poor children of the same age for you, so that although it is a little troublesome, it will also relieve the sixth brother's worries." ”

After listening to Li Zhi's words, Li Su asked, "Can the children of the poor be literate?" If you can't be a brother, don't you have to teach it from scratch? ”

Li Zhi said embarrassedly: "It is always better to teach from scratch than to look at people's faces, and the younger brother thinks it is better to teach from scratch." ”

Li Zhi's brows furrowed again, and he felt that Li Zhi's method seemed to be a little troublesome.

Li Zhi didn't give him a chance to continue thinking, and continued to persuade: "Sixth brother, just imagine, if one day the younger brother's doctrine succeeds, then won't these students all have to follow you and me to increase their prestige?" ”

Li Zhi provoked: "Could it be that the sixth brother is willing to count them all as students of the junior brother and stand at the same height as the sixth brother?" ”

After hearing this, Li Su immediately changed his mind.

He didn't want to become Li Zhi's student with others, wouldn't he be able to stand out himself?

So he immediately spoke: "Brother Wei feels that although this matter is a little more difficult, as long as you work hard, you can still do it." ”

Li Zhi nodded with a smile and said, "The junior brother also thinks that the sixth brother can do it, and at that time, the sixth brother will be the only true disciple of the junior brother's school." ”

Li Zhi's words made Li Su a little embarrassed, but as an elder brother, he became a student of his younger brother.

This made him feel a little difficult to accept.

But he thought about it for a moment and decided it wasn't a big deal.

After all, if Li Zhi's doctrine succeeds, then he can be regarded as a figure who can be compared with Sage Kong.

I can be a student of such a person, and no one will dare to laugh at me.

So he nodded and said, "In that case, then the ninth brother should hurry up and find a disciple for the sixth brother." ”

After Li Zhi heard this, he took Li Yu's hand and walked towards the outside of the iron-making workshop.

It wasn't until he took a few steps that he suddenly slapped himself on the head.

Next, he found Bakken again in Li Su's puzzled gaze.

Li Zhi said to Bakken: "Sending some stainless steel plates to the general as a prisoner, this king is very useful." ”

He was so happy just now that he forgot the purpose of his research on stainless steel.

That's what he used for the distillation of cosmetic ingredients.

In the next two days, Li Zhi really began to ask Liu An to go to various places in Chang'an City to recruit poor children who could not afford to study.

Soon, with his status as the king, he recruited more than 20 teenage children.

Li Su looked at so many dirty peers in front of him, and felt that his head was big.

He looked at Li Zhi with a look of embarrassment and asked, "Ninth brother, do we really need so many people?" ”

Li Zhi said confidently: "Sixth brother, don't worry, it won't be long before you feel that these people are not enough." ”

Li Zhi's words are not casual, mathematics, physics and chemistry are the foundation of all scientific and technological fields.

With Li Zhi's advancement of science and technology, these students will soon be placed in various fields by him.

At that time, Li Su will soon become the commander of the light pole again.
