Third Uncle, upon hearing the news, also raised both hands in agreement.

Second Uncle also shared Li Yu's concerns about natural disasters with Third Uncle. Third Uncle found Li Yu's worries quite reasonable, so he instructed Ju Tianrui and others in the Oil City to not only repair the walls but also reinforce some of the buildings inside.

After delegating a series of tasks, Li Yu made his way to the Research Room.

The Research Room is located in the Weng City between the Second Outer City and the Inner City, and with the increase in personnel, it has also been expanded.

The staff inside had also increased by a few.

For instance, those students who had initially rescued Teacher Liu are now adults, helping out here and learning some knowledge.

Pushing open the Research Room's main door, Li Yu strode inside.

Upon seeing him, everyone paused briefly and called out "Director Li". Li Yu told them to continue their work and not to mind him.

Bai Jie came over, just about to speak.

Li Yu quickly asked, "How's the progress with the aviation fuel?"

Bai Jie gave him a resentful look, but hearing Li Yu's question, she walked ahead of him, saying, "Teacher Kong Shuang and the others are working on it, but not here. I'll take you there."

Li Yu followed behind her.

Passing through a door, they arrived at a relatively spacious area.

A huge vessel filled with black oil appeared before their eyes.

This seemed to be the refining equipment.

Li Yu couldn't understand these devices, but he could feel the heat emanating from beneath the vessel, making the entire space somewhat stuffy.

"Teacher Kong Shuang, Director Li is here," Bai Jie called out to the busy Kong Shuang.

Through this period of interaction, Bai Jie was impressed by Kong Shuang's knowledge and thus respectfully called her Teacher Kong.

Kong Shuang, hearing Bai Jie's voice, turned around in surprise.

Then she said, "Director Bai, I told you not to call me teacher. Director Li, you're here too."

As Kong Shuang walked over, she took off the labor protection gloves she was wearing.

Li Yu nodded and asked, "How is the aviation fuel coming along?"

Kong Shuang adjusted her glasses and explained to Li Yu, "It's still in the refining stage, but rest assured, Director Li, we will have the aviation fuel ready for you in two days."

"Would you like me to explain the refining principles to you?"

Li Yu internally declined, as he couldn't understand, but out of courtesy, he replied with interest, "Sure, go ahead."

Kong Shuang earnestly pointed to the vessel on the far left and said:

"In fact, oil must undergo processing before use to produce petroleum products suitable for various purposes. A common method is fractional distillation, using the principle of varying molecular sizes and boiling points to separate hydrocarbons, then enhance the product's value through chemical treatment."

Li Yu nodded, indicating he understood.

Kong Shuang continued:

"So, this machine heats the oil to between 400℃ and 500℃, turning it into vapor, which is then transported into the fractionating tower.

Look, that's the fractionating tower. In the tower, the higher the position, the lower the temperature. As the oil vapor rises, it gradually liquefies, cools, and condenses into liquid fractions.

The smaller molecules with lower boiling points condense at higher levels in the tower, like fuel gas and kerosene.

Larger molecules with higher boiling points condense at the bottom of the tower, like diesel.

The viscous residue left at the tower's bottom includes asphalt and heavy oil, which can be used as raw materials for coking and asphalt production.

.....

......

Li Yu felt like he understood, but also felt like he didn't. Such matters were best left to the professionals.

When Kong Shuang was about to continue, Li Yu interrupted her, saying, "Alright, very good. Let's discuss the rest another time. In two days, I'll send people over to pick up the aviation fuel. Thank you for your hard work."

Kong Shuang: "Abba Abba....."

Li Yu then left, with Bai Jie, that enchantress, following behind as if with a plan.

But Li Yu mercilessly rejected her, and Bai Jie's eyes were filled with deep resentment.

Li Yu sighed softly.

With no choice, he found a place and had a discussion with Bai Jie, also offering her a glass of pure milk to replenish her energy before leaving.

....

After leaving the Research Room, Li Yu returned to the villa area within the Inner City.

His heart was calm to an almost frightening level.

In the base, everyone was busy now. 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

Whether it was Second Uncle, Li Yuan, or even Li Hang, they each had their assigned tasks.

After delegating responsibilities, Li Yu suddenly found himself idle, with nothing to do.

Preparations were in place for dealing with the impending typhoon; all he needed to do was oversee the process.

With nothing to occupy him, Li Yu, for once, found himself free, so he returned to the villa area's basement.

He took a bottle of red wine from the basement storeroom, then went to the screening room on the underground first floor and selected a movie to watch.

The screening room was well soundproofed. He smoked, drank, and watched the movie leisurely, feeling quite at ease.

This relaxed state was something only available at the Big Camphor Tree Base.

Returning to the base felt like a ship coming back to the harbor; calm and serene, it put his mind at ease.

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

When he awoke, he saw that it was already evening, and the movie on the projector had reached its conclusion.

Li Yu chuckled at himself, then picked up the empty wine bottle, turned off the projector, and headed back upstairs.
