Beyond the door is One Piece

Immortal's perception is very sensitive. Even if someone fell off the cliff in Huaguang Lin, she would know it, and then the right gust of wind would blow the person up.

What's more, the two senior brothers and sisters who have lived under his mountain for nearly half a year.

She didn't show up, not because she didn't want to see these two people, but because she didn't know how to make such a dilapidated martial arts gym rise.

I am an inventor, not an economist. You should ask Ning Guang for this kind of thing!

But he didn't expect that these two people would be fooled away by Zhou Qiqi's method. Zhenjun Liuyun Jiefeng was really curious and couldn't help but come down to take a look and thank him by the way.

"Can't afford to raise them?" Xianhe was stunned for a moment: "Then when he finds that he cannot raise so many sons, won't he still come to trouble me?"

"How could it be?" Zhou Qidao said: "He can come now because he is single and has no worries. But then he will have a wife and children. If he comes to seek immortality, what will happen to the children?"

Zhou Qike understands the sorrow of a married man very well, and he only has the ability to have the time and space, otherwise he would be raising a child with Robin right now.

"You bastard..." Xianhe no longer knew what to say, so he could only change the subject: "Although you didn't mean to do so, you did a great favor to Liuyun Jiefeng Zhenjun, so you came to seek immortality. What's the matter? ah?"

"Oh, that's it!" Zhou Qidao: "We are here to become apprentices, seek immortal magic, and learn the path to immortality!"

"Seeking immortality?" Xianhe nodded. This answer was not beyond her knowledge. Eight out of ten people who came to seek immortality came to be apprentices.

"Then why are you seeking immortal magic?" Xianhe continued to ask.

"For cultivation and immortality!" Zhou Qidao.

"Eh?" Xianhe was stunned for a moment. This answer was actually different from others.

Very few people seek immortality for the purpose of immortality. Basically, they want to create some kind of career, family, etc.

"What about after immortality?"

"After immortality, I will continue my current career, travel the world, and save people!" Zhou Qidao.

The crane is even more confused. Traveling around the world to save the common people?

Where is this going?

"What are you doing now??" Xianhe looked Zhou Qi up and down: "If you are saving people, you must be somewhat famous, but why haven't I seen you?"

"Because I just came to this world and the work hasn't started yet!" Zhou Qidao.

"Can you still travel across the world?" Xianhe smiled. She felt that Zhou Qi was lying, but she was not prepared to expose it.

After all, I am a kind person, and it is much more interesting to embarrass him with words than to expose him directly.

Just like modern people, they prefer to let people break their defenses rather than scolding other people's parents directly.

"Since you are already doing these things, what difference does it make whether you are immortal or not!" Xianhe asked.

"Of course there is a difference!" Zhou Qi pointed to Noelle beside him: "For example, Noelle is 16 years old this year. If I had died 16 years ago, I wouldn't have met Noelle, right?"

"Eh?" Xianhe was stunned.

"If I had died yesterday, I would not have met such a lovely and respectable immortal like you!"

Leave the clouds and borrow the wind: ....

Although you praise me, I am a little happy.

…."There are so many beauties, delicious food, beautiful scenery, and inventions in the world. As long as you live long enough, you can slowly see them all. But if you die halfway, everything will be over!"

"But immortality also has its troubles. You have to watch your relatives and friends grow old one by one in front of you, leaving only yourself in the end..." Xianhe asked: "Don't you think this is a curse? "

"Why is this a curse? This should be a gift!" Zhou Qidao: "There are two deaths in a person's life. One is when the brain completely loses activity, and the other is when there is no more life in this world. When people remember him!”

"But my relatives and friends will always be remembered because of the existence of me, an immortal. Maybe a hundred or a thousand years later, I will still tell their stories to the children on the roadside!"

"That is to say, they will never die a second time!"

"Sir, tell me, isn't this a gift?"

"This!" Xianhe was confused, completely confused!

Can you explain it like this?

Moreover, what he said is not unreasonable. My comrades, relatives and friends passed away one by one, so that there are no words related to them left in this world.

But are they really forgotten?

No, I still remember them!

Since people in the world have forgotten, it should be me who reminds everyone of them again. This should also be the meaning of my immortality!

"Mortal, you have convinced me!" Xianhe said.

Zhou Qi looked happy: "So you want to accept me as your disciple?"

"You come up first!"

After a while, the three of them arrived at an island in the middle of the lake in the center of Mount Aozang.

There is an altar table here. When mortals want to see Liuyun Jiefeng Zhenjun, they will offer three dishes on it.

The purpose of their search for immortals had been known by the immortals on the road, so the immortals naturally had a good idea and would come forward if they could solve the problem. Those who only sought money and wealth were not seen.

It was Zhou Qi and the two who were traveling around the mountains and rivers all the way. They looked like tourists. Unexpectedly, they were also looking for immortals.

She had to ask questions herself, so she didn't even have to eat the tribute.

In front of the two of them, the crane stretched its body, and streaks of light appeared on its body. In the blink of an eye, the ordinary white crane turned into a crane nearly three meters tall with a body full of lights.

Crane looked at the dumbfounded Noelle proudly, wanting this kind of reaction.

But when he saw Zhou Qi with a calm face next to him, he was immediately speechless. Are you so calm?Did you know this before?

But considering the wisdom he just showed, it’s not impossible!

Thinking of this, Zhenjun Liuyun Jiefeng suddenly no longer felt excited. Instead, he felt a little embarrassed. So in his eyes, I just looked like a monkey!

"Ahem!" Xianhe straightened his voice and said: "It is impossible to become a disciple. I have not accepted apprentices for a long time, but I can teach you the immortal magic. What kind of immortal magic do you want?"

She didn't intend to teach those advanced immortal arts. Mortals wouldn't be able to learn them in a hundred years. She just wanted to get rid of them with some basic skills.

Although your words make sense, they are only worth so much.

…."What kind of immortal magic do they have?" Zhou Qi asked.

"There are seven elements of magic: water, fire, grass, ice, wind, rock, and thunder. There are talisman techniques and Xumi meson techniques!" Xianhe said: "Fire and thunder techniques are powerful and suitable for fighting. Grass moves Immortal Dharma Master’s life is also what you need most. Wind Immortal Dharma Master’s speed, Rock Immortal Dharma Master’s defense, Water Immortal Dharma Master’s treatment, and Ice Immortal Dharma Master’s control. After practicing, they also have the effect of calming down and stopping thoughts, so they are suitable for learning. For research purposes!”

"As for the talisman and Xumi Jiezi techniques, unless you plan to live here for a long time, I don't recommend you learn them!"

"Is it okay to learn everything?" Zhou Qi asked.

Xianhe was stunned for a moment, and then raised his eyebrows: "What are you talking about? You, a mortal, are really greedy. It would be great luck for others to learn even one skill, and you still want to learn it all?"

"If you don't learn them all, how will you know which one is suitable for you?" Zhou Qidao: "What if my body is suitable for the thunder element, but I choose the ice element, wouldn't it be a waste of time?"

"Eh..." Zhenjun Liuyun Jiefeng was panicked, what do you mean by this?

I used to ask people to choose one of the seven immortal arts. Could it be that those who failed to practice it were because they didn't choose the right one, rather than because mortals were not suitable for cultivating immortals?

Doesn’t this mean that I have tricked many people?

How can it be!

That's because they don't have enough blessings to be destined for immortality. It has nothing to do with me!

But feeling guilty, the immortal began to hesitate in his tone: "But this is against the rules!"

"Whose rules?"

"Of course it's my rule. The people who seek immortality next to me only learn one volume, and you learn seven volumes. Doesn't this make me, an immortal, unfair?" Zhenjun Liuyun Jiefeng said: "Since they are all here to seek immortality. Yes, then everyone should be treated equally. If you choose an immortal method that is not suitable for you, there is nothing you can do about it. It is all your fate. Xiaohe is back!"

"Huh?" The two of them turned their heads and saw a tall girl with a white ponytail in front of her, a stunning appearance but a cold face, jumping up from the mountain with a basket of medicinal materials on her back.

His temperament is out of this world, and he seems to be able to see the immortal energy lingering in his movements, as if a real immortal is alive in this world.

Judging from the appearance alone, he is even more like an immortal than the crane Liuyun Jiefeng.

When the girl saw Zhou Qi and the others, her face showed no emotion. Instead, the water turned into ice, and she entered the Immortal Cave by stepping on the lake water.

"Shen He, my disciple!" Zhenjun Liuyun Jiefeng is still very satisfied with this disciple. Not only is he good-looking, he has a good figure, and his cultivation qualifications are also first-class.

Moreover, he is born with divine power!

For this reason, she often showed off to others, and even asked a design master in Liyue Port to design the most beautiful set of clothes for her disciples to wear.

It's a pity that this disciple's personality is too cold, and I don't know if he can integrate into the human world in the future.

Zhou Qi knew, however, that Shen He was cold on the outside and hot on the inside. The longer his emotions were suppressed, the more intense they would be when they exploded. It was not that easy just to impress her.

"Immortal, didn't you say you haven't accepted any disciples for a long time? Why are there still disciples here?" Zhou Qi pointed at Shen He's back: "Looking at her age, she shouldn't have been a disciple for more than ten years..."

"Ten years, it's been a long time!" Liuyun Jiefeng Zhenjun said.

…."Ten years, is that a long time?" Zhou Qi scratched his head. Ten years ago was only 2014, and the derailment of the article seemed like just yesterday...

"Hey, you're a very quibbling person. My disciple is born with ice-cold muscles and jade bones, and her talent is amazing. Can you compare with her? If you keep doing this, I won't even give you a chance to pick and choose!"

"Okay, okay!" Zhou Qi raised his hands in surrender: "Then there are two of us, can we choose two?"

"That's right!" Originally, she planned to only give one door, but since Zhou Qi just asked for nine doors, she refused, and now she wants two doors, but she is too embarrassed to refuse.

"In that case!" Zhou Qidao: "Let's get a piece of grass type, and then a piece of talisman technique!"

"Are you sure?" Zhenjun Liuyun Jiefeng frowned: "The little girlfriend next to you possesses the power of the rock elemental god, so it is clear that the rock immortal method is the most suitable for her!"

Why is this man only thinking about himself? Am I wrong?

"The Rock Walking Immortal Technique is suitable for Noelle, but we can only get two Immortal Techniques from you, so we can only choose the rare ones!" Zhou Qidao: "Next, we will continue to search for immortals. There are many Immortals in Liyue. , each person needs two doors, and he only needs to visit five people to collect them all!”

"Hey, you..." Zhenjun Liuyun Jiefeng was completely numb. He told me to visit other immortals in front of me. Aren't you afraid that I would tell other immortals directly and let them reject you directly?

But she couldn't refute, who told you not to accept others as your disciples!

"Only these two books!" Zhenjun Liuyun Jiefeng no longer wanted to see these two people: "Just a quick note, if you have any questions, ask immediately. You have three days. After three days, no matter whether you have completed the training or not, you will Gotta leave!”

Zhou Qi took the two books and flipped through them. Seeing that Lord Liuyun Jiefeng was about to leave, he hurriedly shouted: "Immortal, please stay!"

Liuyun Jiefeng Zhenjun staggered at his feet. What's going on with these words? Why does he feel so terrifying!

But she still stopped, turned around and asked, "What else is there?"

"Well, that's it!" Zhou Qidao: "Sir Suwen, you are proficient in the study of mechanism structure!"

"Hey..." After saying this, Zhenjun Liuyun Jiefeng was happy.

After all, immortality is just an identity, and institutions are life. I just didn’t expect that my fame would be so great. Do even the immortal seekers who come to visit me know about it?

"You actually study this way?" Liuyun Jiefeng Zhenjun asked.

"Yes!" Zhou Qi nodded: "It's just that this research institution needs to use a lot of arithmetic problems, but there are a few problems that I can't figure out, and I want to ask the immortal for some advice!"

"If you want to study mechanisms, your level of arithmetic cannot be too low. You have found the right immortal. If you try another immortal, they will never be able to answer it!" Zhenjun Liuyun Jiefeng said with a smile: "You tell me, what is the problem?"

"First of all, we call integers larger than 0 positive integers, such as 1, 2, 3, 4, 5..."

"Well, then what?"

"Within the range of positive integers!" Zhou Qi continued: "We call positive integers such as 2, 3, 5, and 7 that can only be divided by themselves and 1 prime numbers!"

Liuyun Jiefeng Zhenjun nodded. Although this was the first time she heard about the concept of prime numbers, it was not difficult to understand, and she could calculate countless prime numbers in an instant.

"And an integer that can be divisible by numbers other than 1 and itself is called a composite number!" Zhou Qi continued: "For example, 4 can be divisible by 1, 2, and 4, then it is a composite number!"

"Yeah!" Zhenjun Liuyun Jiefeng continued to nod, so positive integers are composed of prime numbers and composite numbers?

Oh, there is another special number, 1, which is neither a prime number nor a composite number.

"Then there is also the concept of even numbers, which refers to positive integers such as 2, 4, 6, and 8 that are divisible by 2!"

Liuyun Jiefeng Zhenjun nodded, this concept is not difficult to understand: "So, what is your problem?"

“是这样的，我们发现4=2+2，6=1+5，8=3+5，那么是不是就意味着任何一个大于2的偶数，都可以写作两个质数之和？”

Now that you have understood the concepts of positive integers, prime numbers and composite numbers, let’s prove Goldbach’s conjecture!

"Of course!" Zhenjun Liuyun Jiefeng nodded subconsciously, suddenly feeling something was wrong.

2, 4, 6, and 8 are even numbers, and 2468 is also an even number.

This problem still holds true when the unit is small enough, but does it continue to hold true when the number is large enough?

Liuyun Jiefeng Zhenjun suddenly discovered that this problem did not seem to be that simple!

On the other side of the door is the Pirate King.
