One of the simplest examples is Ji Chen's construction of an undersea tunnel.

In the undersea tunnel, Ji Chen is the chief designer.

But any of the pipes, any steel bars, or a piece of cement are not produced by Ji Chen!

It's thousands of workers who come to produce and manufacture!

But the humanitarian reward will still fall on Ji Chen without any suspense.

Just because, the person who designed the undersea tunnel is Ji Chen.

Ji Chen is the most critical part!

In short, it is feasible to replace the construction workers.

But replacing Ji Chen is not feasible!

The same is true for this set-up.

If Lin Zhuan Xi couldn't understand this formation......

Where Ji Chen asked her to arrange, she would arrange it, what was the difference between that and ordinary workers who built undersea tunnels?

Ji Chen is still the chief designer!

Lin Zhuan Xi can only be regarded as a "construction party".

In this case, the formation attracted the Yanshan Dragon Vein, and finally brought the Heavenly Dao reward, which would inevitably fall on Ji Chen's body.

And Lin Zhuan Xi couldn't even get a little bit of a corner.

Because of this, Ji Chen had to let Lin Zhuan Xi thoroughly understand the knowledge of this formation first.

Let her really understand the formation.

Only by arranging this formation can Lin Zhuan Xi also be rewarded by the Heavenly Dao.

In fact, technologies such as optical brain technology and iron-ion batteries are similar.

There are a few differences, though.

Because of the light brain technology, iron-ion battery and other technologies, the main thing is to gather the power of humanity.

To obtain the Heavenly Dao reward, it must be recognized by the Heavenly Dao.

The way of heaven is difficult to deceive.

But to unite the power of humanity, we only need to obtain the approval of "people", that is, the approval of the people.

Humanity is still easy to be deceived by comparison.

You only need to say that it is the technology provided by Lin Zhuanxi when it is promoted, and that's it.

The patent belongs to Lin Zhuanxi, and everyone will believe that it was Lin Zhuanxi who invented the optical brain and iron-ion battery technology.

As long as no one comes forward to fight for these patents.

In fact, the original owner of these technologies was Ji Chen, and it was impossible for Ji Chen to compete with Lin Zhuanxi. As for the others, they can't fight if they want to.

It's like many people know that Edison was a great inventor with more than a thousand inventions.

But in fact, few people know that Edison actually organized a team to invent and create together, but the results belong to Edison.

Even if someone knows the truth, they won't investigate it in detail.

The public still only knows Edison, and they don't know the obscure inventors behind it.

Therefore, in terms of humanitarian power, Lin Zhuan Xi does not need to worry more.

Now, she only needs to concentrate on studying the method of arranging the formation.

Jiang Yunyan and the commemorative memory were listening to it from the side.

Little Lori's memorial is to make soy sauce.

Although she is very smart, the matter of arranging the formation, after all, involves a lot of complex mathematical knowledge, which is not something that the current commemorative mind can master.

Of course......

When I really need to let her study, I throw her calculus textbooks for elementary school, middle school, or even college first, and let her read them by herself for a month or two.

After that, it will be unimpeded.

"The formation has a great relationship with geometry in mathematics. ”

"If you have a deep understanding of geometry, it is relatively easy to learn formations. ”

"Zhuanxi, Yunyan, do you have any research on geometry?"

Ji Chen looked at Lin Zhuanxi and Jiang Yunyan and asked indifferently.

"I know, I know!"

Jiang Yunyan was the first to raise his hand.

"In middle school, I was always at the top of my math rankings!"

"Geometry is also very good!"

"No matter how complicated the geometry problem is, I can solve it!"

She said proudly, and glanced at Lin Zhuanxi with a sense of superiority.

"I ...... It seems that I don't know much about geometry in mathematics. ”

Lin Zhuanxi said truthfully.

In her memory, everything in the mortal world seemed to have been forgotten by her.

She knew she had some basic knowledge of mathematics.

But it's not clear what exactly geometry is studied.

Anyway, in my mind, I don't have any geometric memories at all.

"Hmmm......"

"In that case, let me talk a little bit about some of the basic theorems of geometry!"

Ji Chen said.

Lin Zhuan Xi didn't remember that he knew geometry, so Ji Chen simply talked about it.

Normally, if you want to complete all the theorems of geometry, there is not a year or two that you can't do it.

Even if you are a genius, it will take a year.

However, immortal cultivators, especially immortal cultivators above the human immortal level, obviously can't guess their brainpower with common sense.

Ji Chen just talked about these theorems a little.

Explain a little.

Lin Zhuanxi nodded immediately.

Say you get it.

The total number of basic geometric theorems is only fifty or sixty, and it is still very simple for Lin Zhuan Xi to understand them all.

"Now, I'll give you a few geometry problems, and you can practice them first. ”

Ji Chen said next.

"Brother-in-law, you can just ask the question!"

"I can definitely answer it easily!"

Jiang Yunyan said proudly.

"Hmm!" Ji Chen nodded slightly.

He quickly came up with a few geometry problems, all of which were extremely complex and closely related to the formation he was about to arrange.

Jiang Yunyan rubbed his hands and immediately began to try to solve these geometry problems.

And yet—

When she saw the first geometry question, she frowned directly.

With a sad face, there is no way to answer.

Lin Zhuanxi, on the other hand, had a flat face, and after a little review of the question, he began to answer.

It's just a matter of moments, and the first complex geometry problem has been perfectly solved by Lin Zhuanxi. Soon, it's the second, the third......

Fourth! Fifth!

It took less than 20 minutes, a total of five complex geometry problems, all of which were solved.

At this moment, Jiang Yunyan was still struggling with the first geometry problem, and he didn't even have a clue at all.

"Little aunt is so stupid!"

"I can't do such a simple question!"

Commemorative Nian watched from the side, and said seriously.

Jiang Yunyan's face was bitter.

"Little girl, you're smart!"

"Brother-in-law's questions are too difficult!"

"I can't answer the ...... at all"

Jiang Yunyan said with a bitter face.

Seeing that Lin Zhuanxi next to him had successfully answered the answer, Jiang Yunyan's little face showed extreme surprise.

It's not that she's stupid, it's because ...... Lin Zhuan Xi was not as she expected, she had no understanding of geometry, and she was not as profound about geometry as she thought.

How old is Jiang Yunyan in total?

It's only seventeen.

It was the age when I had just started high school.

In fact, because of the recent period of time, the aura of heaven and earth has recovered, and her martial arts cultivation has progressed extremely fast, in order to impact the grandmaster realm, she has put down all her studies in the past few months.

Her real education is nothing more than ......

Junior high school only.

Her geometry is good......

It's just at the level of junior high school.
