After a thousand years of trading, start a million barrels of oil

Chapter 50 Delivery
The young man smiled and said, "Of course, I told you that it will take five days to get it, and it will be delivered on time."

Jiang Fan nodded and said, "Then give it to me."

The young man didn't blot out any ink, and took out a disc the size of a one-yuan coin from his breast pocket,

It's a bit like the electrode pads you put on when you go to the hospital for an EKG, but it's a little smaller than that,
There is a smaller protrusion in the middle of the disc, which accounts for about one-third of the diameter of the disc, and it looks like it should be made of metal.

The young man put the wafer into the transfer cabinet and operated it on the holographic panel.
The holographic panel on Jiang Fan's side was notified that there were items put in the transfer cabinet and they could be picked up now.

Jiang Fan manipulated it, and a transfer cabinet appeared in front of him out of thin air.

Opening the cabinet, the small disc that was in the young man's hand just now appeared in front of him.

Jiang Fan took it out, put it in his hand to observe carefully, and rubbed it with his hand from time to time, it turned out to be such a thing.

Holding the disc in his hand, Jiang Fan felt that the edge of the disc was not the adhesive tape of the electrode sheet, but a material similar to plastic.
It has texture, but it is not hard, and it is very elastic.

The metal protrusion in the middle is also a round arch, without sharp edges, so it will not scratch people.

Jiang Fan reckoned that the core should be inside this small round arch.

But how to use it?

Jiang Fan looked at the young man and said, "It's quite small, but how do you use it?"

Young people are used to Jiang Fan being too focused on ancient culture and forgetting many modern things, so he explained directly:

"Just stick it on the skin. It will automatically connect with the brain through the nervous system of the human body by means of electrical reactions to achieve auxiliary functions.
As long as it is attached to the body, the brain can retrieve the knowledge content in it anytime, anywhere.

Of course, while using it, the brain is also being baptized to complete the digestion and absorption of knowledge, and finally completely transform the content in the patch into its own knowledge. "

"It can be pasted anywhere?" Jiang Fan checked to see if there was a specific location requirement.

"Yes." The young man said: "There are neural connections everywhere. With the current technology, no matter if it is separated by one centimeter or 10 meters,
This difference in nerve conduction distance will not have any effect on the use effect at all.

However, from the perspective of convenience and aesthetics, we usually stick it on the back.

And it is waterproof and drop-proof design, you don't have to worry about it.

The period of use is one year, but generally within one year, you have basically digested the knowledge inside. "

There were no other questions, Jiang Fan thanked the young man and left the space.

Back in the bedroom, after Jiang Fan studied it, he stuck it on his back as the young man said.

The moment he pasted it, Jiang Fan instantly felt a current flow into his mind from the place where the patch was pasted on his back.

The whole brain felt numb, and then a lot of things began to pour into the brain,

It was very chaotic at first, I just felt like a mess of energy-like things,

But then, these things gradually became clear, and Jiang Fan could even roughly distinguish the various contents in them.

Advanced Mathematics, Linear Algebra, Probability Theory
The subjects of university mathematics flooded into my mind,

Under the subdivision, the catalog of each course can be clearly identified,
Functions and limits, derivatives and differentials, differential mean value theorem, definite and indefinite integrals.
Various directories began to connect with Jiang Fan's brain,
Then, in more detail,

Mean value theorem, L'Hopital's rule, Taylor's formula, Fourier series, Euler's equation.
Until the end, every formula and every letter entered Jiang Fan's mind.

Jiang Fan felt as if he suddenly became enlightened about mathematics knowledge. The mathematical formulas that were like a bible before seemed so familiar now, as if he could use them flexibly and at any time with his own hands.

Amazing!

The whole process lasted for two hours, which made Jiang Fan a little tired and fell asleep.

Went to Lin Wan school the next day, Lin Wan was very happy to see Jiang Fan taking the initiative to accompany him these days,
After chatting for a while, Lin Wan looked at the time and said to Jiang Fan, "Come with me to class today."

"A class?" Jiang Fan had never attended a class on a university campus.

"Go." Lin Wan acted like a baby.

Jiang Fan thought about it, okay, so he asked, "What class are you taking?"

Jiang Fan thought that the financial courses are nothing more than financial management, economics, accounting, etc.
At that time, he would trick Lin Wan into sitting in the back row, and Lin Wan would listen beside him, so he could play with his mobile phone,

If it is not allowed to play with the mobile phone, he will call the content in the knowledge patch to browse and browse, so as to promote the brain's learning of the knowledge inside.

Lin Wan replied to Jiang Fan: "Go to high mathematics."

"High math?" Jiang Fan was surprised when he heard Lin Wan's answer.
