These children were specially selected from the children's group, all of whom were over 12 years old, and they were born with a sense of science. This is only relatively speaking, so far Hong Tao has not found a single genius among the more than forty children.

What this yard was for, now unveiled, is Hong Tao's chemical laboratory plus gunpowder workshop. It is not a place where gunpowder is manufactured in large quantities, but a laboratory where gunpowder is classified and developed.

After the ratio of ingredients and the effect of the experiment are completed here, it will be mass-produced in the gunpowder workshop of the forbidden army. The children of the children's group are still responsible for the final mixing process, and others can only start, unable to obtain the formula, even if they look at it secretly, they will lose their heads.

These kids aren't adults, and if they say whoever sees who is dead, they're going to kill you.

When there is no oil, Hong Tao can only take the children to kill time with trona. Make a soap, a small-scale trial production of glass or something. The purpose is not to mass-produce, but to see who of them has a talent in this area.

Hong Tao does not plan to launch these new products for the time being, first, there is no manpower, and second, there is no shortage of money. As long as he looked at the large expanses of rice bags on the slopes of the west of the city, Hong Tao was full of contempt for the word money.

Moreover, the new products cannot be pushed one after another, but must be slowly accepted and accustomed to by the ancients, and give full play to the added value of each commodity.

Now Hong Tao is not concerned about launching new products to make money, but about how to get explosives out. Nitrocellulose is too dangerous, and the means of passivation are too complicated, and it is not a short-term energy production.

What to do? No way, we have to start with incendiary bombs, walk slowly step by step, give these children enough time to study and research, so that we can get more chemical talents in the future, and I can't wait.

If you want to get incendiary bombs, you have to have gasoline, this thing is relatively easy, even if there is no oil, when Huangzhou's grain reserves are sufficient, and the crown does not need to transport a large amount of grain, you can change to coal tar, which can also refine gasoline.

However, the arrival of Zhu Bajin saved Hong Tao a lot of trouble, and also saved Wang Guan a lot of trouble. Coal tar not only smells bad but also poisonous, and cannot be mixed with other goods, and the transportation cost is not small.

"This is called the fractionation column, the useful substances in the oil will be heated into water vapor-like mixed oil and gas into the fractionation column, the higher the temperature in the tower, the lower the temperature in the tower, different densities of oil and gas will condense to different degrees, and then flow out along the cooling port next to the fractionation column.

What we need to do is to determine the temperature and cooling level in the column, and after we understand this, we can fractionate the same things in the oil that are useful to us according to our needs.

But this is a very boring and careful work, you may have to do many tests, you need to record a lot of data, make a mistake, lose one, and the previous test will be in vain. Come on, I'll do it today, everyone watch, go and bring a tank of oil, and you two will make a fire. ”

How to fractionate oil, Hong Tao no longer has to think about it. At that time, in the Jinhe Empire, the petrochemical industry was explored little by little by himself with people, and the approximate fractionation temperature only needed to be done according to the standard size. This two-meter-tall pure copper guy is a miniature version of the Jinhe Empire's fractionation tower, which is not very suitable for mass production, and it is just right to do the test.

But he didn't want to directly tell the children how high the condensation port should be set and how much the temperature of the preheating furnace should be appropriate, so that although the product came out quickly, the children still didn't understand the principle.

I want to figure it out, in addition to theoretical knowledge, it is to let them keep experimenting. Without this patience, it is not suitable for this job, and it needs to be replaced.

"What's the matter?" Before the fire was fully burned, there was a knock on the courtyard door, and it was still Lian'er.

"The imperial court is going to send someone to inspect Huangzhou, this is the official document that Tongchuan Fort has just delivered, and now the Su officials are afraid that they have already passed the Zongcheng." Lian'er handed a piece of paper to the colt, and at the same time briefly explained the main content of it.

“…… It's kind of interesting, the Su official you are worried about is here. Hong Tao still can't recognize all the traditional characters, which is also the main reason why he is not willing to read the official document.

First of all, Su Shi returned to Beijing and became an official, although his rank was only promoted by half a level, but his real power was greater. Hong Tao is not optimistic about Su Shi as an official, let alone about him becoming an official.

The comfortable environment is the grave of the poet, and to engage in literary creation, you must go through ups and downs to be inspired. It seems that because of his appearance, the trajectory of the great poet's life may be about to undergo a major change, and it is very questionable whether the poems that have been handed down to future generations can continue to appear.

Secondly, Su Shi's temporary position in Huangzhou is a bit intriguing, just three words to patrol Huangzhou, and he doesn't even have an official position. It can be seen that the emperor doesn't want to see this great poet, and he doesn't plan to give him the right to fart. Since it's a patrol, you can only bring eyes and ears, and it's useless to have a mouth, let alone point fingers and interfere in local military and political affairs.

Finally, and most interestingly, is the timing of the arrival of this document. It is worth it to arrive at Tongchuan Fort at about the same time as Su Shi and his party, which means that after this document is delivered to him, Su Shi's people will arrive in Huangzhou City in a day or two. If he really wants to see something, it's really hard for him to hide it.

It seems that the forces that want to make themselves unlucky are not without a way, the emperor can protect himself, and they can try all kinds of ways to defeat themselves. Isn't this an obvious conspiracy, so that you can't say it, and I'm afraid you'll have read everything that people should see and want to see before the official document arrives.

This trick is really difficult to deal with if it is replaced by other officials, and it is basically equivalent to a surprise inspection, and if there is no one in the DPRK and China to report the news, it will be easy to expose the stuff.

But it doesn't have much effect on Hong Tao, because he doesn't know how many emperors and secret agents of the imperial court there are around him, and what he does is basically transmitted in real time, and there is a fart secret in addition to what he thinks in his head.

Are you still afraid of surprise inspections when you have no secrets? After all, he is also the central commissioner of the town guard, and the daily trivial things such as a few puddles of cow dung on the street and someone arguing in the market will definitely not have any effect.

If you want to impeach a high-ranking official trusted by the emperor, you can't just open your mouth, whether it's the imperial history or the official, you have to come up with some evidence, whether it's physical evidence or human evidence.

The so-called rumors of the Song people do not mean that the official can run the train with his mouth full of clothes and impeach others at will, so the officialdom will not be chaotic.

Behind the rumors, there is also a large set of rules that regulate the behavior of the spokesman himself. With the urine nature of the Zhao family in the Song Dynasty, there is no lack of checks and balances in everything, and the same is true for the officials.

"The official is talking nonsense again, when did the concubine think about other men!" Lian'er has become a woman with a colt, and she has indeed changed a lot.

In addition to still liking to stuff all kinds of snacks into his mouth, diseases such as star-chasing and brain-dead powder seem to have been cured, even if he knows that Su Shi will arrive in the next two days, he doesn't have any special expression.

"It's still hard-mouthed, don't worry about why Zhu Bajin didn't mention it, but you were so excited when you came with the surname Su?" Hong Tao still didn't give up, and made a very tangled look to ask.

“…… I won't tell you, Ziju and I are going to visit the children, lest they be spoiled by the children's group again! "Even if Lian'er has three heads, she can't break her as an official, so she just turns around and leaves.

She and Ziju were very bored in Huangzhou City, except for dealing with a lot of official correspondence every day, they couldn't find anything to do, and they couldn't even go shopping.

However, their age was not as good as water, so they simply learned to get a group of poor Tibetan children with horses, and they took food and clothing to relief and relief when they had nothing to do, claiming to surpass the children's group, and they would all go to the Jinshi examination in the future.

Hong Tao pretended not to be convinced, and he was not optimistic about these children. In fact, he was deliberately stimulating Lian'er and Ziju, so that the two of them would be more motivated.

In fact, Lian'er and Ziju's actions just make up for Hong Tao's anger, and the families of European and American politicians and wealthy businessmen usually join in philanthropy, and the Chinese are not used to it, but Hong Tao thinks this is very good.

I kill people and offend people outside all day long, and my family can make up for each other by doing more good deeds, at least there is no harm. For this reason, Hong Tao deliberately increased Lian'er and Ziju's monthly regular money, saying that it was the salary for handling official documents, but in fact, it was to find an excuse for them to have money to engage in charity.
