Hand over the jade seal first [Infrastructure]

Xiao Zirong reached out and hugged Xiao Xuexing's waist, and said in a low voice, "Brother, can we talk about it tomorrow? I'm so tired."

Xiao Xuexing pinched his chin and looked at him carefully, probably because he drank some wine at night, Xiao Zirong's eyes were moist and bright at this time, the tails of his eyes were red, and there was hope in his eyes.

Xiao Xuexing made a decisive conclusion: "I think you look good, you shouldn't be tired."

Xiao Zirong argued: "The body is not tired but the heart is tired. Nothing is better outside than at home. I haven't slept well for a long time."

Xiao Xuexing was very ruthless: "It's okay, you can sleep more tomorrow."

The negotiation failed, Xiao Zirong was silent for a while, let go of Xiao Xuexing, turned around and ran away.

Xiao Xuexing stretched out his hand angrily and amusedly to drag him back by his collar, then he resisted on his shoulder and said: "It seems that you are used to running, this problem really needs to be corrected."

When Xiao Zirong was thrown on the bed, she only had time to say: "It's been a long time since I've done this, please take it easy!"

Then... and then he was indeed as Xiao Xuexing said, when he woke up the next day, the sun was already high.

But this time, he didn't feel any sore back, instead he was refreshed. Thinking about it, Xiao Xuexing was merciful yesterday.

Of course, when he saw the faint red mark on his ankle, he thought of the excitement that he had nowhere to escape last night, but... the excitement is the excitement, and the excitement is really cool.

When he got dressed, Xiao Xuexing was walking from outside, and when he saw Xiao Zirong, he said, "I've already sent someone to take Heda Taylor to Jiankang."

Xiao Zirong was a little surprised: "Send him away now? Don't let him stay here longer?"

Xiao Xuexing narrowed his eyes slightly: "Do you still want to continue to face him day and night and teach him how to write hand in hand?"

Xiao Xuexing couldn't help but blushed slightly when he heard the word "writing": "Don't talk nonsense, whoever is holding hands, he is so old, you are so jealous for no reason!"

Such an old age... Xiao Xuexing was silent for a while, and said with some difficulty: "He is only 35 years old this year."

And he is 32 years old this year, sometimes Xiao Xuexing can't help worrying, as time goes by, he will also worry that he is so much older than Xiao Zirong, and when he was 40 years old, Xiao Zirong was still In the prime of life.

Xiao Zirong looked shocked: "What? I thought he was 40 years old."

In fact, if you think about it carefully, Teller is not particularly old, but the other party feels to me like the kind of eminent monk who sees through the world, and the whole person is very gentle.

In addition, Turkic people have darker skin, so he always felt that the other party should be the age of his parents.

Xiao Xuexing glanced at Xiao Zirong subtly: "Like this?"

Xiao Zirong immediately said: "That's not true. I just want to see if I can weaken the strength of the Northern Wei Dynasty through Yeda. Anyway, Yeda is a nomadic people, so I don't need to think about the development of people's livelihood. Robbing the Northern Wei Dynasty is also a good choice."

Xiao Xuexing didn't say anything more, and after a long silence, he said, "I'm going back to Jiankang in two days."

When Xiao Zirong heard this, he felt a bit reluctant: "Why do you have to leave so soon?"

Xiao Xuexing patted his head: "Your Majesty has taken a step back, we should give him face."

The relationship between him and Xiao Xuan was already very tense before. If it wasn't for Xiao Zirong's sudden escape, I'm afraid Xiao Xuan couldn't bear it anymore and wanted to do something. We will not usurp the throne, but it will definitely suppress Xiao Xuan's power. He seized power.

It can be said that Xiao Zirong's running has eased the relationship between Xiao Xuexing and Xiao Xuan, and the superficial peace between the two has been restored.

According to normal reasoning, Xiao Xuan would definitely be more afraid of Xiao Xuexing, and would be more aggressive in wanting to seize power from him.

However, Xiao Xuexing's attitude made Xiao Xuan very helpless. Basically, as long as he had nothing to do with Xiao Zirong, Xiao Xuexing would act like a Buddha.

What can Xiao Xuan do?He is also very desperate.

One of these two people turned against each other when they disagreed, and the other ran away when they disagreed.

Xiao Xuexing's meaning is also very simple, Xiao Xuan has already given them face, and they can't really be so ignorant.

Xiao Zirong had no choice but to say: "Then... okay?"

Xiao Xuexing said: "I'll come and see you after Mid-Autumn Festival."

Although Xiao Xuan turned a blind eye, the King of Jinling's order not to enter Beijing is still there, and it should not be withdrawn in a short time.

After all, he had expressed his firm thoughts before, and took a step back in such a short period of time. Xiao Xuan couldn't make another step back. Does the majestic emperor not want to lose face?

Xiao Zirong sighed for a long time: "I don't know when uncle will be able to figure it out."

Xiao Xuexing said: "It's probably impossible to figure it out, you should think of something else."

Xiao Zirong also felt that it was a bit difficult to force others, but it was the only way to do it now.

After sending Xiao Xuexing away, he rolled up his sleeves and started to invest in the development of black fire oil.

With something that has a scientific basis, Xiao Zirong can directly hand over formulas and the like to the subordinates for them to study, but when facing new things like black fire oil, he still needs to come in person.

There are three main products of black fire oil, that is, petroleum, the first is gasoline, the second is kerosene, and the third is diesel.

All three are obtained by distilling petroleum, where the gasoline fraction needs to be less than 170 degrees, and the kerosene fraction needs to be between 170 and 230 degrees.

As for diesel oil, it is divided into light diesel oil and heavy diesel oil. The fraction of light diesel oil should be between 230 and 270 degrees, and the fraction of heavy diesel oil should be between 270 and 350 degrees.

These temperatures are not difficult to achieve, and the only difficulty is probably the distillation tower required for distillation.

The distillation of black fire oil uses atmospheric distillation and vacuum distillation, and the synthesis of atmospheric and vacuum distillation, and the device is roughly divided into three: steaming hall, cracking, and coking.

Needless to say, steaming hall, and the nature of cracking is divided into thermal cracking and catalytic cracking.

Catalytic cracking is basically the addition of catalysts to thermal cracking, and there is also a hydrocracking capability that they have not yet been able to conduct this experiment, so Xiao Zirong directly excluded this.

Anyway, the reaction principles of catalytic cracking and hydrocracking are the same, and they are carried out according to the carbocation reaction mechanism.

Thermal cracking is simply heating and proceeds according to the free radical chain reaction mechanism.

Xiao Zirong originally wanted to choose catalytic cracking, because thermal cracking is irreversible, but such things as catalysts cannot be researched in a day or two.

He could only give up the research on the catalyst first and continue to toss the distillation tower.

The coking part is actually a further step of cracking, allowing heavy oil to continue to undergo deep cracking and condensation reactions at high temperatures.

Zhai Ling was flattered when he saw the thick stack of explanatory documents from His Royal Highness again after many years.

At the point where Xiao Zirong is now, he will not do many things in person, unless it is very difficult or he is very interested in the type.

But this time Xiao Zirong almost studied the distillation tower with his subordinates, and then distilled the black fire oil into different oils step by step.

Of course, such distillates are actually very rough, and the quality is not ideal. For example, gasoline has a lot of gum, diesel has a low cetane number, straight gasoline has a low octane number, and so on.

This needs to be adjusted again.

But the quality of these things still needs to be tested through real use.

Among them, the engines used in gasoline and diesel are different. Gasoline requires an ignition engine, while diesel requires a compression ignition engine.

"Your Highness, what about the kerosene?" Zhai Ling was a little surprised. It was obviously useful for His Highness to put away the kerosene.

Xiao Zirong thought for a while and said, "kerosene can be used to replace other oils to light lamps."

Zhai Ling was rather disappointed after hearing this: "Ah, so it's useless?"

Useless?How could it be useless?Kerosene can be made into aviation kerosene, which is the fuel for jet engines.

It's just that this kind of engine has quite high requirements for kerosene and needs to be specially produced, and their current technology has not yet reached it.

Of course, if you want to do it, you may be able to do it for ten or twenty years. After all, he has so much information in his hand, which can help the aerospace industry avoid many detours.

But Xiao Zirong doesn't plan to take it out now.

For the current state of Qi, the aerospace industry is the most useless thing.

And he was also worried what if everyone knew that there was a chance to go to the sky, and they all enthusiastically engaged in spaceflight?

It sounds very exciting to strive for the aerospace project with the whole country's financial resources, but if you really do this, you will be waiting for the country to perish!

Now the people of Qi State have not even been able to get rid of poverty in an all-round way. Let alone getting rid of poverty, it is impossible for more than half of the people to enter a well-off society. Go back and spend that money on aerospace. Don’t look back. Excessive taxation and rebellion.

After analyzing the pros and cons, Xiao Zirong kept the matter a secret from anyone except Xiao Xuexing.

However, even a very calm and rational person like Xiao Xuexing was very interested when he heard that he had the opportunity to go to heaven, and asked him many questions.

Xiao Zirong saw that it was really bad, Xiao Xuexing was just showing interest, if it were someone else, he would wish to go to heaven immediately to seek longevity.

However, he could somewhat understand Xiao Xuexing's thoughts, even though the other party was very healthy and looked very young, Xiao Xuexing didn't mind the fact that he was ten years older than him.

Xiao Zirong is also a little bald about this matter, he can enthusiastically express his love to Xiao Xuexing, but this kind of thing needs to be adjusted by Xiao Xuexing himself, of course Xiao Zirong has also reflected on whether he does not feel safe enough for Xiao Xuexing .

After all, the state of the two of them getting together less and more apart is indeed unstable. Xiao Zirong sighed and could only continue to study the engine. The track for the train is being laid, but once the engine research is successful, the car is always more convenient than the train Many times, it will be extremely easy for him to meet Xiao Xuexing when the time comes, and it may be able to appease Xiao Xuexing's heart that is sensitive due to his experience when he was young.

On the day when the ignition engine was initially successful, a news came from Jiankang: the emperor issued an edict to confer the title of Bashan King as the prince on August [-]th, to announce to the heaven and earth, and to sacrifice to the Taimiao.
