Liquid fractions with larger molecules and higher boiling points condense at the bottom of the tower, such as diesel.

The viscous residue left at the bottom of the tower is asphalt and heavy oil, which can be used as raw materials for coking and producing asphalt.

....."

.........

Li Yu felt that he understood, but he felt that he did not understand. This kind of matter should be left to professionals to solve.

When Kong Shuang was about to continue speaking, Li Yu interrupted her and said, "Okay, very good. Let's talk about the rest next time. In two days, I will send someone over to get aviation kerosene. Thank you for your hard work."

Kong Shuang: "Aba Aba..."

Li Yu then left, and Bai Jie, the goblin, followed behind, seeming to have an agenda.

But being ruthlessly rejected by Li Yu, Bai Jie's eyes were extremely resentful.

Li Yu sighed leisurely.

.......

After leaving the scientific research office, Li Yu returned to the villa area in the inner city.

It's a bit scary to be calm inside.

In the base, everyone is busy now.

Whether it's the second uncle, Li Yuan, or even Li Hang, they all have their own division of labor.

After explaining the matter, Li Yu suddenly became an idler with nothing to do.

People have also been assigned to take charge of the things that need to be prepared before the typhoon comes, so you only need to keep an eye on them afterwards.

There was nothing going on, and Li Yu rarely had a moment of leisure, so he returned to the basement of the villa area.

I took a bottle of red wine from the basement warehouse, then went to the screening room on the first floor of the basement, and immediately chose a movie to watch.

The soundproofing effect in the screening room was very good. He smoked and drank while watching the movie leisurely, feeling very uncomfortable.

This kind of relaxed state can only be found in the Da Zhangshu Base.

Returning to the base is like a ship answering the harbor. The sea is calm and makes people feel relaxed.

A movie and a bottle of red wine, Li Yu drank until he was tipsy and slowly fell asleep.

When he woke up, he saw that it was already evening and the movie on the projector had played to the end.

Li Yu laughed at himself, then picked up the empty wine bottle, turned off the projector, and answered on the ground.

.....

Li Yu had a lot of leisure these past two days, running around in the base. He saw that everyone had become accustomed to the current rhythm and was busy on their own.

The most important thing is that they are all working in the corresponding work, and they have gradually mastered it.

This made Li Yu very happy.

Seeing this scene, Li Yu also sighed in his heart. This is exactly the purpose of building this base. There is strength in numbers. Only by gathering people together and working together can we build a stronger base.

If you fight alone, it will be too difficult to survive in this apocalypse, and you will be worried about zombie attacks every day, which is completely different from the ease now.

The key to being able to achieve this point lies in food and people.

When food is sufficient, people will be at peace, and reliable people can unite and use their strength in one place.

Otherwise, like some forces, although there are many people, the intrigues, power struggles, and internal friction are too serious.

Li Yu is very happy. The current Da Zhangshu Base is looking more and more like what he imagined.

After spending two days leisurely like this.

Finally on this day.

Li Yu and the others are going back to the Oil City Walled City.

The main reason why I want to go back this time is to establish a transfer station between the Oil City and the Da Zhangshu Base.

This chapter is not over yet, please click on the next page to continue reading! On the other hand, Li Yu also wants to go to the Oil City Walled City to see the progress of wall repairs.

The firearms and ammunition in the helicopter have been moved to the warehouse and are now empty.

In the morning, Li Yu sent Li Tie to the scientific research office to bring over the aviation kerosene needed for the helicopter.

After refueling the helicopter, this time they used aviation kerosene instead of diesel. They no longer had to stop for refueling like last time.

While saving time, it also eliminates the risk of stopping to refuel.

soon.

Li Yu asked Cannon and his helicopter to push into the urn city.

At this time, the door opened, and He Chao walked in with Zuo Ruxue and the others.

It was obvious that Zuo Ruxue and the others seemed a little nervous, after all, they were going to such a far place.

Due to the reminder from their second uncle, they did not carry too many things.

Li Yu looked at them, waved and let them board the helicopter.

Jackal has had a good rest these past few days. After communicating with Xiaoyong in the past two days, he found that Xiaoyong seemed to be more optimistic than before.

I made a few good friends in the inner city, but I heard from him that he was always beaten violently by Xuanxuan during the boxing class.

Jackal was quite pleased to hear that Xiaoyong had been asking him to teach him some fighting skills for the past two days.

The helicopter was filled with fuel, and Li Yu, Li Tie and others, as well as Zuo Ruxue and others, all boarded the helicopter.

There was no cargo in the helicopter this time. Li Yu and the others only carried some firearms and ammunition that were enough for the few of them.

So more people can be loaded.

Twenty or thirty people like Zuo Ruxue got on the helicopter, and there was no problem at all.

It's just that Li Yu always feels like there's something wrong and nothing can be done.

It wasn't until he saw his third aunt that he remembered it.

He didn't bring any fruit for his third uncle, so before taking off, he quickly asked Li Yuan to bring out two sacks.

Thrown on a helicopter.

Huhuhu——

As the helicopter took off, Li Yu looked at the gradually shrinking Da Zhangshu base.

I murmured in my heart: By the time I get back from this trip, the typhoon is probably about to arrive.
