After reading the information on the parchment, the cat-eared girl asked Zhang Feng curiously:

"Master, what is this black oil?"

Zhang Feng was stunned for a moment, and then spoke thoughtfully:

"If I guess correctly, the 'black oil' that this rat Daqiang said may be oil..."

"So what is oil? Oil flowing out of the stone?"

Windsor was still confused.

"This is a long story, and oil has many uses. Anyway, it is definitely a good thing!"

Zhang Feng pinched his chin. If it was really oil, it might have provided a lot of help for his subsequent plans.

First of all, one of the most important uses of oil is fuel. Although Zhang Feng already has a clean and pollution-free energy such as mysterious crystal, this thing is too rare after all, and only he can afford it.

Those noble merchants who had their own steamed cars still used wood, coal and other fuel. It was not that they could not afford the mysterious crystal, but that Zhang Feng had no intention of selling it.

If fuel can be refined, it may be very helpful for ordinary people.

Not to mention, besides fuel, oil has many other uses, such as plastic, asphalt, clothes, synthetic rubber, etc.

In other words, if these things are really oil, Zhang Feng would not have to move many things in modern times, and he would be completely self-sufficient here!

This also means that countless wealth is like Zhang Feng, and of course, it doesn’t matter whether it’s money or not. Zhang Feng just wants to protect himself under the threat of orcs, that’s all.

"Then aren't we getting rich?"

Hearing Zhang Feng's explanation, Windsor's eyes flashed with the shape of money.

"I'm not sure if it's oil, so it's hard to say. You reply to Rat Daqiang and ask him to transport some black oil samples back."

"Uh-huh!"

Seeing the cat-eared girl leave happily, Zhang Feng gently tapped the table.

If these things are really oil, then he has to be prepared.

After all, it is not a simple matter to use this oil. First of all, it is a problem of equipment. This thing cannot be made in another world for the time being, so I can only go to modern times to buy it.

Then there is how to use oil, which requires refining equipment and also needs to be purchased from Modern Times.

As for more details, you also need to learn in modern times.

then.

Zhang Feng returned to the bedroom, his eyes closed and opened.

World changes.

In front of me is a minimalist room with a round alarm clock hanging on the warm white walls.

The time points to 5:31 pm, the same as the time when I left last time.

While Zhang Feng stood up from the sofa, the aristocratic dress on his body instantly turned into a casual outfit.

Buzz ~

Suddenly, the phone in my pocket vibrated.

Since Zhang Feng basically put his mobile phone in the storage space when he was in another world, there was no loss of power.

The caller ID is Lin Yulan.

Reach the phone.

"Zhang Feng, I bought a big fish today and I will make pickled fish later!"

The microphone was a little noisy, but I could still hear the refreshing female voice clearly. Zhang Feng's expression was a little complicated, and he said:

"Okay, please trouble you."

Although in Lin Yulan's opinion, she and Zhang Feng had only been seeing each other for half a day, for Zhang Feng, a month has passed.

So psychologically, Zhang Feng always feels a little guilty.

After all, strictly speaking, Zhang Feng doesn’t spend much time with Lin Yulan than others.

However, after Zhang Feng finished answering, the other party fell into silence.

"Hey, are you still listening?"

Zhang Feng was a little strange.

"...Well, Zhang Feng, I... can't make pickled fish..."

After a long time, Lin Yulan's weak voice came from the opposite side.

“…”

Zhang Feng slapped his forehead.

He almost forgot that Lin Yulan didn't know how to cook.

So Zhang Feng had no choice but to speak helplessly:

"I'll do it."

"Yeah OK!"

Lin Yulan nodded quickly, and Zhang Feng vaguely heard something like "I want this big one".

More than ten minutes later, I heard the sound of footsteps coming from the corridor outside the door, and Zhang Feng opened the door.

Lin Yulan, wearing an ol suit and carrying a black plastic bag, was looking for the key.

Seeing Zhang Feng open the door, she subconsciously wanted to throw herself into her arms, but considering that she was still holding a big fish in her hand, she held back.

Seeing this, Zhang Feng naturally took the fish over and then gently hugged Lin Yulan.

"Hehe, go and make pickled fish, I'll help you!"

"good."

An hour later, Zhang Feng brought a large pot of pickled fish to the dining table.

The two of them had nothing to do with each other and didn't need any other dishes, so they just started eating.

After the meal, Lin Yulan told Zhang Feng some interesting things in the workplace, and Zhang Feng listened quietly.

"Zhang Feng, do you have something to tell me?"

Lin Yulan suddenly spoke in confusion.

"Uh, I'm having something to ask you to help..."

Zhang Feng scratched his head embarrassedly. Every time he encountered trouble, he would come back to Lin Yulan for help. After the trouble was solved, he immediately went to another world. He was simply treating Lin Yulan as a tool man, and he felt embarrassed.

"You said, I can definitely help!"

Lin Yulan wiped her mouth and said another silently in her heart.

If I really can't help, my dad can definitely help!

"I want to buy something, such as drilling and oil production equipment, refining equipment, etc., but because there is no way..."

"This is a small matter!"

Lin Yulan agreed immediately, and then she asked curiously:

"By the way, if you buy these strange things like this, have you discovered the oil field?"

"No, just I have a friend who wants it."

"Oh, leave it to me! It's guaranteed no problem!"

Lin Yulan didn't look at it carefully. She had long been used to Zhang Feng's strange behavior.

Since he is back, Zhang Feng plans to stay for a while. In addition to buying these things, he also has to learn some basic knowledge.

Otherwise, if you get the thing over, it won’t work.

So, Zhang Feng entered the study.

Because Lin Yulan... his father has a wide connection, Zhang Feng easily bought relevant equipment and then fell into learning.

Although the seller was surprised that this person spent such a large price to buy these things, he didn't know anything? But he still agreed with Zhang Feng's request.

I don’t know if it was a mutation myself. Zhang Feng felt that he was learning things very fast. Basically, he only needed someone else to teach it once. He could read the manual or something.

The teachers who taught Zhang Feng were amazed at this. If they hadn't discovered that Zhang Feng knew nothing about these things before, they would have thought that this was an old worker.

During the learning process, Zhang Feng found that his storage space had become larger again.

Originally, he thought that it would take several times to transport things, but the space could be improved for a lot of time.

A month passed in a flash, and Zhang Feng had basically learned things related to the oil field. Although he had not practiced it much, this knowledge seemed to be deeply engraved in his mind.

Then there is transportation.

Although these tools are very large, Zhang Feng has a large storage space. He can hold one-third of the storage at a time, and it only takes three times to be almost done.

"Hmm? What is this?"
