The HRE Daoist blew.

The trees by the lake flew into the air as if they had been uprooted and planted somewhere else.

As soon as you breathe in, an open space forms around you.

"It's not good."

"Yes, those four great immortal sects actually stood by and watched when we were besieged by the Demon Sect....."

The Shinra Daoist waved his right hand slightly.

In this newly formed open space, a small and simple house gradually appeared in front of Guo Liuyu's eyes as if it had grown directly out of the soil.

"Oh....."

Guo Liuyu nodded.

If this is the case, the Shinra Dao people can only unite the demon clan if they want to take revenge.....

"Being a teacher is not a person with a small amount of energy, but those people accepted our affiliated sect and helped the Demon Sect kill your senior brother and sister, which is a bit excessive..."

The Shinra Daoist finger tapped into the river, and fish swam around out of thin air.

He pointed to the sky again, and countless birds appeared in the air and flew into the mountains and forests.

"If you hadn't been in retreat at the time, I'm afraid you would have lost your last apprentice."

In the woods, there was a roar of beasts.

Although Guo Liuyu was just a mortal, he could also feel that the surrounding woods were less quiet and more vibrant.

"By the way, your cultivation is sealed for the teacher, and your spiritual root is also abolished for the teacher."

The Shinra Daoist put the math book and a bunch of other books that he didn't know what to do on Guo Liuzhu's cloud.

"Being a teacher is also for your own good."

He didn't say anything more after taking a deep look at Guo Liuzhu, and once again stepped back into the Shenluo Sect.

"Hiss ....."

"I see!"

Guo Liuyu took a deep breath.

It seemed like he had accepted a bit too much just now.

"What kind of books are these? .....”

In addition to the math book that he was particularly familiar with, there were three other immortal books that the Shenluo Daoist had just placed on his cloud.

The Book of Immortals/.....

"'Array', this name is really concise."

Looking at the one-word name, Guo Liuyu nodded approvingly.

"....Vladivostok?"

"..... Brahmaputra River Formation?"

However, the next two books made Guo Liuyu really gasp.

He silently withdrew his approval.

"Master, is this for me to study the formation?"

Guo Liuyu sat on the cloud and flipped through these books.

Little did he know at this moment that he seemed to have made a name for himself because of mathematics.

......

Divine Sword Sect, Great Cloud Peak.

"Senior brother, does that Guo Liuzhu really know the law of eternal life?"

Li Shanyun, the senior brother of the Divine Sword Sect who came back from the Immortal Ascension Conference, nodded with a cold face.

Just now, his master's voice suddenly echoed in the sky above the entire Divine Sword Sect.

"The Law of Eternal Life ......"

"Does this really exist in the world.....

.......

Qiankun Sect, a secret room somewhere.

"Master, do you really want to invite Guo Liuyu over?"

"Disciple, the law of eternal life, the art of slaughtering immortals, who doesn't envy it?"

"But why did he tell us..... After all, we also participated in the ..... of the HRE Sect"

"Just because he has a little junior sister, and we have the elixir."

"Also poison ....."

......

Dan Wang Zong.

"Gu Ju, I don't need to tell you the way to the Shenluo Sect."

"No need, master."

A girl in a pale cyan dress with long hair reaching the ground knelt on one knee.

"Remember, your task is to learn the method of eternal life and obtain the Eternal Life Treasure Book, and if necessary, you can also marry that Guo Liuzhu."

"But the master.... The eldest disciple of the Shinra Daoren........ Isn't it your own ........?"

She looked up, and there was a small tear mole in the lower left corner of her left eye.

This tear mole did not make her look fierce, but with the natural and soft eyebrows, she made her body a little more weak out of thin air.

A trace of weakness that people can't help but care for.

"So Gu Ju, whether you can make this Guo Liuyu willingly tell you the method of eternal life depends on your own ability......

Star Glory Sect!!

"Master, I'm sure that Yu Xiaoxiu is a demon clan, and the disciple's blood trick can see through at a glance that she is not a human."

"I didn't expect this Shenluo Daoist to dare to have an affair with the demon clan, and why did the Yuluo Demon have to do that Yu Xiaoxiu.....

"Master, aren't we also having an affair with the Demon Sect?"

"Apprentice, how many times has the teacher told you, we have joined the Demon Sect, and we are now the Demon Sect."

"That master, how can we show Yu Xiaoxiu .....?"

"No, no, no, in vain, just hand it over to other sects, our target has become that Guo Liuyu, he knows the existence of the law of eternal life............................"

"Master, the apprentice's blood technique can also be reborn with blood if he cultivates to the Mahayana realm."

"Disciple, the Dafa of Soul Detention for the teacher can see the life of all things in the world, only the Pythagorean theorem, which the teacher can't see through, is the real eternal life......

The human world, the Ming Dynasty.

"Your Highness, the minister is sure that there is not a word of truth in what he says."

The Great Emperor of the Human Realm was dressed in a dragon robe and stared into the distance with a frown.

Eternal life....

Who doesn't yearn for it?

"Your Highness, Guo Liuzhu's junior sister Jin Dan will inevitably come to the mortal realm to cut off the mortal silk before the period, and at that time..."

"You stand down first."

"Huh."

The Great Emperor of the Human World slowly stood up.

"If I could live forever, then I would be on this throne...... Don't ..... either."

.....

Mortal realm, Great Zhou Kingdom.

"Father, this is the only way to save the queen mother."

"Shut up!"

King Zhou roared angrily.

But he saw the tears on his daughter's face.

"Daughter, you are much more important in the hearts of your father and queen mother than the art of immortality, without you, what is the meaning of eternal life?"

"The daughter knows, but.... The daughter can't sit idly by, father, the Divine Sword Sect is about to choose a saint, as long as the daughter becomes a saint.............."

"But how can you fight with those Yuan Babies for your cultivation of Jindan?"

"Trust me, Father."

In addition to tears, Zhou Lanruo's eyes also flashed with determination.

"Wonderful......"

Guo Liuyu held the "Vladivostok Formation" on the clouds from time to time to let out a sigh of admiration.

Although it was the first time he had read these books, the body was very impressive.

He just skimmed it and a myriad of ideas and questions came to mind.

And these problems can be solved by thinking mathematically.

For example, at which point the layout can be brought into the plane Cartesian coordinate system or polar coordinates.

The zoom in and out of the formation can introduce a scale bar.

The superposition of several arrays can be seen as solid geometry.

The dismantling of a single array can be understood as factorization.

The arrangement of juxtaposition formations can become a sequence problem.

According to the different effects of the formation, different formations can be classified by the method of collection.

Through the calculation of probability, you can know where the trigger point of the array is set, and the enemy has the highest chance of triggering.

He could even find out the relationship between the amount of aura stored in the array and the amount of power after triggering the array by listing the unary equation.

It's getting late.

Seeing that Yu Xiaoxiu was also immersed in cultivation, Guo Liuyu quietly put the math book in front of her.

Presumably, after practicing, Yu Xiaoxiu, who was tired after practicing, saw the word mathematics for the first time, and he would definitely be extra surprised and happy.

"Pick a (1,0)."

Guo Liuyu flew straight towards the first mountain on the right side of the Shenluo Sect.

The HRE Sect is (0,0), the four peaks are (1,4), and you can choose another one (1,0) to besiege a right triangle.

Most of the formations are circular.

A right triangle can be more perfect and simpler to inlay in a circle.

After all, the center of the circle is the midpoint of the hypotenuse.

Tomorrow, I will first do a great array of protectors to practice my hands.

Although he had only learned the formation for a few hours, Guo Liuzhu had the original memory and the assistance of mathematical thinking, and he felt that he had mastered it without modesty.

"Do I still want to build my own house.....

When he arrived at the peak, Guo Liuzhu found that there was nothing here.....

"Let's start with a name.....

Guo Liuzhu, who was sitting cross-legged on the clouds, racked his brains and thought for a while.

"Otherwise, let's call it the Six Animal Peak......"

With the infiltration of the mind of the Shinra Dao people, he thought naturally.

After all.....

This is the peak he obtained when he was seventeen years old......

It's still quite memorable.

"Let's build a house first......

Erasing the idea of naming this peak as the Six Beasts Peak in his mind, Guo Liuzhu took out the "Brahmaputra River Formation".

Although he has no cultivation, the reason why the formation is popular is because as long as he is proficient enough, even mortals can arrange a formation to kill immortals.

So it seems.......

It seems that it is not wrong for mortals to be able to slaughter immortals....
