Li Chengqian made up his mind, and gradually gained confidence in his heart, and some things that had been left behind a few days ago gradually came to mind.

I remember that in later generations, by chance, Li Chengqian read a material on the history of photography, which mentioned an early photosensitive material. It's just that at that time, because it was very difficult to buy a lot of materials, he threw this information aside after reading it and didn't care about it.

But just a few days ago, under the prompting of the broken convex lens, Li Chengqian suddenly remembered the lens of the camera, and then naturally thought of the photosensitive material.

How about getting a camera in Datang? Li Chengqian had never thought of this problem before, but now that he thought of it, he really wanted to try it himself.

If it succeeds, when the time comes, whoever is not honest will put their soul in a black box and scare those turtle grandchildren to death.

Returning to 'Lanruo Temple' without saying anything all the way, Li Chengqian beckoned Ye Mei over: "Xiao Ye, you will arrange for someone to go to the prison of the Criminal Department to bring out all the monks who were arrested before." ”

"Whoa!" Ye Mei is not a person who talks much, so she took Li Chengqian's order and turned to leave.

Only Yang Yuxin, the little girl, was curious, and after the night charm left, seeing that Li Chengqian had nothing to do, she took the initiative to ask: "Your Highness, what do you want those Fang Shi to do?" Do you want to do alchemy? ”

"Dan, who is a fart, thinks he didn't die fast enough, right?" Li Chengqian rolled his eyes, looked at the little girl's puzzled look, and explained: "Those bastards are all bold and active, they are all talents, but their energy is not used in the right place, this time the palace will correct them well." ”

Li Chengqian studied chemistry in his later life, and naturally knew that this was a very important subject, so he did not plan to bring all these things in his mind into the soil in the future.

But Li Chengqian didn't want to be a teacher and make students start from scratch, so he naturally thought of those monks who were not afraid of death.

These guys would dare to prepare such a dangerous thing as sulfuric acid with a broken furnace, and if they were given glass goggles and a simple gas mask with toner, they would probably dare to develop chemical weapons.

So Li Chengqian decided to bring in all those alchemists, teach them some necessary knowledge, and then let them prepare some chemicals.

Anyway, these people have already been sentenced to 'life' for their past behavior, and instead of dying in prison in the future, it is better to work hard to contribute to the country, and maybe they may be released early.

And with these alchemists, the next time you need dangerous goods such as ****, nitric acid, sulfuric acid, soda ash, etc., you don't need him to go out in person.

Li Chengqian was only 13 years old, and he didn't want future generations of students to see such a sentence when they were studying history: Li Chengqian, who died in a chemical explosion for five years after Zhenguan, was a pioneer in the history of chemistry and a great chemist.......

Seven or eight Fangshi, after a short time, were brought into the 'Lanruo Temple', looking at them one by one to lose weight, as soon as the wind blows, Li Chengqian sighed helplessly, it seems that the words 'rising in the day' are really harmful.

But now is not the time to talk about this, these guys have been brainwashed, it is useless to say anything, the most direct way is to let them see some strange things, use the magic of chemistry to arouse their curiosity, and then let them consciously devote themselves to research.

There is only a thin line between geniuses and madmen, and the persistence and exploration of the unknown by these alchemists is already the basic quality necessary to become a scientist.

The palace, almost all of these scholars have entered, even if they have not entered the palace of the Tang Dynasty, they have also entered the palace of the former Sui, so they are not curious about everything in the palace, and even look at Li Chengqian's eyes with contempt.

"His Royal Highness the Crown Prince, isn't he also interested in the way of immortality?" A monk said mockingly. This guy is the one who refines the 'Rejuvenation Pill', and he is considered a 'master' in this group of alchemists.

"Immortality? Like you guys? All of them are like tuberculosis ghosts? Li Chengqian pursed his lips and immediately returned to color.

These guys can't get used to it, and the more they get used to it, the bigger their temper becomes.

The 'master' was not moved by Li Chengqian's attitude, and asked without changing his face: "Since His Highness doesn't want immortality, then what's the matter of recruiting us here?" ”

"Naturally, let you toads at the bottom of the well open your eyes and see the world." Li Chengqian waved his hand to the guards who were escorting a few Fang Shi and motioned for them to come with him.

The next time is Li Chengqian's performance alone, preparing sulfuric acid solution little by little under the gaze of a group of monks.

About half an hour later, about half a teacup of concentrated sulfuric acid was freshly baked, packed in a transparent cup, and brought to the front of the monks.

"His Royal Highness the Prince, what do you want to do?" 'The master' asked with a serious face.

Armed from head to toe to teeth, Li Chengqian had already let him know the danger of the contents of the cup, so he was very worried that the little boy in front of him would let him drink it.

"Don't worry, I won't let you drink it." Li Chengqian wore a mask filled with toner on his face, and his voice was full of anger.

Then, in the midst of everyone's curiosity, Li Chengqian asked for the three-edged military thorn from the hand of the night ghost, and dipped the tip of the military thorn into the liquid in the cup.

There was a violent reaction between the steel and the concentrated sulfuric acid, and a little bit of white gas came out of the mouth of the cup, accompanied by an unpleasant smell.

Terrible, this is simply terrible, after a moment later, after the military thorn was taken out by Li Chengqian, the sharp part in front had all disappeared, and it was obvious that it had been corroded by those liquids like water.

A liquid that even steel can corrode, what the hell is this? What happens if someone drinks it?

The monks each turned their thoughts, and it seemed that they wanted to ask Li Chengqian about the formula of this thing. But because of the rules, they held back, and in ancient times, unless they were masters and apprentices, or relatives, they would not tell anyone else about formulas and other things.

Li Chengqian put the cup aside, put his gloved hands into the clean water to wash it, and then untied the various equipment on his body little by little: "Do you want to know what this thing is?" Want to know its formula? ”

"What's, what is this?" The 'master' was a little nervous, and glanced at the cup that was not far away.

"It's called sulfuric acid, it's an acidic substance, it's highly corrosive, of course, it can be neutralized with a strong base, and when the ratio of acid to base reaches a certain level, then it becomes a harmless substance."

Li Chengqian talked eloquently, the most basic scientific work is carried out on the scholars, these people are the foundation of the future Datang chemical industry, and they must be cultivated well.

However, the things he said were still too profound, and when the scholars heard it, their eyes were already circled, and they entered a state of confusion, watching Li Chengqian's mouth open and close, not knowing what he was saying.
