On the 16th day of the ninth month, Bi Lingkong suddenly felt something in his heart and began to retreat.

Before the retreat, she said: "In Pan Long's book, at least a dozen paths to immortals and Buddhas can be summarized. My math level is too low, so it's easier to try first, and if no one has one to take it yet, I'll take it all at once. Maybe by the time the books are printed, I'll already be an immortal Buddha. ”

From the demon god to the immortal Buddha, it is true that it has come full circle, and it is quite a waste of time and efficiency. But it is also beneficial - first of all, the demon god has an unlimited lifespan and has a short enough time to find a suitable road; secondly, the demon god himself has already been in contact with the source of the world, and even has used obsession to link it to the source of the world, so once he finds the road of the immortal Buddha, if he wants to occupy the road again, it must be much easier to re-hook it, maybe he doesn't even need the normal "get on the bus first and then make up the ticket", and he will be done with the demon god qualification as a ticket......

Of course, this is just an idea. Since ancient times, I have never heard of any demon god who later cultivated into an immortal Buddha.

Perhaps, but those predecessors did not leave a record.

Among the known immortal Buddhas and demon gods, Bi Lingkong was the first to make the attempt to "transform from a demon god to an immortal Buddha".

So since she started retreating, Lan Lingquan and Lie Yukou have been guarding the World Outer Building every day and never leaving a single step. The only time Pan Long left was to transport the World Outer Tower to a deserted island more than a thousand miles outside Guangling City, dig a pit in the rock, and hide it in it.

No one knows what will happen when the demon god turns into an immortal Buddha. If there is really any natural or man-made disaster, the two immortals should be able to stop it by joining forces. The distance of thousands of miles should not harm the innocent.

Seeing that the book had been completed and the teacher was still in retreat, Pan Long couldn't help but be a little worried.

"It's not strange for an immortal to retreat for a hundred and eighty years, it's only been a few days!" Lie Yukou said nonchalantly, "You go about your own business first, and we'll contact you when her retreat has results." ”

Pan Long left, he looked at the book, and fell into deep thought.

According to the teacher, the paths that can be summarized in this book are not very deep and complicated. Although it is true that no one in the Kyushu world has published relevant research results, it may not be that no one has studied them, and even has already taken up the road - it is just that the quasi-immortal Buddha who has occupied the road is working hard to make up for the lesson, and has not had time to publish the results and gain the public's attention and recognition.

This is also a very common situation among the immortals and Buddhas. Many immortals and Buddhas are like this, first find a path that can be passed, occupy it by themselves, and obtain incomplete immortality. Then I went back and worked hard to study this path, and finally researched the results, published them, gained recognition, and completely perfected my immortality with the help of feedback from the world.

It's also considered ...... Standard process.

After all, there are very few people who can get feedback from the world before they live forever, so as to determine the path.

If you publish your results, but you have not been able to get public recognition and feedback from the world, and at this time, someone reads your results, understands the path you are taking, and takes the lead, then even if you get feedback from the world in the future, you will not be able to live forever.

That kind of situation happened more than once in the Warring States period, and between the strong man who took the road and the wise man who found the road and got feedback, there was bound to be a desperate struggle in the end, and only by winning this fateful decisive battle could the results and the road be reunited and complete immortality.

Of course, this is not without room for compromise. But the side that occupies the road has no way to back down, let the way out, and when the other party joins the way, it is the time of death when he is so big that he dies. Only the side that gets the feedback from the world can give in, but they must first rely on other paths to cultivate the Immortal Buddha, and then they can extract the feedback they get from this path and give it to the other party.

In the past, among the four saints of Confucianism, "benevolence" and "righteousness" were all opened by themselves, and "filial piety" and "ritual saint" were divided by "benevolence" to them, so as to achieve immortal Buddhas.

According to Bi Lingkong, in the past, there were actually far more than three ways for "Rensheng" Lu Fuzi to get feedback from the world, but it was a pity that he was killed by Zhao Sheng with Zhou Tianxingdou Array, and he has not been resurrected so far, so most of the roads he received feedback on back then are now in a state of no one cares.

The "quasi-immortal Buddhas" who occupy the road without receiving feedback do not age, but their longevity is limited, only about 500 years. Since the immortals and Buddhas of the hundred schools were killed by Zhao Sheng, it has been a thousand years.

It's funny to say that when the hundred schools of thought were destroyed, many masters were excited, and hurriedly seized those paths that could be found according to the theory of the hundred schools of thought, and no one had yet cultivated the path to life. As a result, who knew that the immortals and Buddhas of the hundred schools would not return for a long time, and after they occupied the road, they found that this path had actually been fed back, and there was no way to improve immortality, and they couldn't even negotiate with the corresponding immortals and Buddhas.

This is like the public transportation in Pan Long's previous life, the seats were occupied by them, but the tickets were bought by others. If they refuse to transfer their tickets, they will have to wait to be punished.

Those who illegally occupied seats in their previous lives only need to be fined. But the illegal operation of the road to immortality is not so easy!

When you get in the car, you can't get out!

In the end, these people died one by one, and they died extremely aggrieved.

If they honestly find their own way, they may be able to achieve far more than one immortal Buddha.

It is precisely because of this that in the thousands of years of the Great Xia Dynasty, except for the "Drunken Immortal" Chen Yan, there is no second person who has cultivated to become an immortal Buddha. All the immortals have all taken the path of demon gods.

After all...... No one knows that they are ready to take the road, whether they were "booked" by the former sages of the hundreds of schools of thought.

Ren Changsheng is a bloody example, he looked for the road several times, and each time he found that this road was either occupied by someone or booked by someone - in fact, it was all the same, could he still find the immortal Buddha who booked this path and let the other party make way of it?

So he had to change and change, and gradually fell old. If it weren't for Pan Long helping him use the Holy Grail Circle to seize the life of the demon beast to prolong his life, I am afraid that it would not take a few years for him to grow old and die.

But now, he has a new opportunity!

Pan Long flew all the way to Suitao Mountain and met the old ancestor who was studying.

Since solving the problem of lifespan with the help of the Holy Grail Circle, Ren Changsheng has not only alleviated his physical aging, but also relaxed his spirit. His room was filled with books, and he was obviously immersed in research, trying to find a path that had not yet been discovered by anyone before, and to continue his quest to become an immortal Buddha.

He was very happy to see Pan Long coming.

"I have heard about your help to persuade the young master of the Cang family to convince the elders to complete the marriage. He said, "Cangyuan is indeed not bad, he has both talent and good character, and he is a person who is worth helping him." You chose to make friends with him instead of Delonan, you have a lot of vision!"

"The old ancestor has seen Di Luonan?"

"Met once. Ren Changsheng said, "Di Luonan is very talented, and from a distance, I feel that he is the kind of person whose talent is so high that it makes people blush." But he is also quite cold, and the people in this world who can make him care about them are afraid that they will be counted on one hand. At that time, I felt that if this person became the Son of Heaven, it would not be a blessing for the people. ”

"What about Emperor Hedong?" Pan Long asked curiously, "Have you seen him?"

"Naturally, I've seen it. He is mediocre, but it can be seen that he is a person who is willing to learn and refrain. This kind of person can't be a saint or a virtuous monarch, but he should be a master of success, and there is no problem in thinking about it. ”

"I heard that Emperor Hedong is generous, what do you think?"

Ren Changsheng shook his head: "Then I can't say." He is not the kind of person who has a strong nature, it is possible to do good or evil, rise and fall. I can only say that he is a middle-to-upper figure among all the beings in the world, barely higher than the 'mediocre', nothing more. ”

Pan Long smiled: "In this way, Di Hedong may not have won Di Luonan?"

"Not necessarily. Ren Changsheng said, "Who is the emperor, we don't count, Emperor Renchen says it." And what Di Renchen thinks, I can't be sure...... Perhaps he felt that choosing a talented heir was the most important thing. Perhaps he felt that the emperor did not need too much talent, and that a person who was willing to bow his head to learn and restrain himself was more suitable...... Who's for sure?"

"Haven't you observed Di Renchen?"

"Of course I did, but when I observed him, he was only a fifteen-year-old boy. After so many years, people will change. ”

"You didn't observe him again?"

"After the Son of Heaven ascended the throne, he was protected by Kyushu's luck. All the methods of divination and qi observation had no effect on him. I tried to observe him, but I only felt vague, it was possible, and I couldn't see any conclusions. ”

Only then did Pan Long understand, and he couldn't help but sigh.

No wonder Kyushu has always had the saying that "the heart of heaven is unpredictable" and "the heart of the monarch is unpredictable", it turns out that it is not only because of the emperor's high power, but also because of luck.

After saying these gossips, he took out the book and introduced the things he had studied during this time.

When he learned that the first demon god in Kyushu, the Confucian sage "Yiwu" personally admitted that this book may contain more than a dozen immortal Buddha paths, Ren Changsheng's breathing couldn't help but be a little heavier.

After asking Bi Lingkong about the path he was going to try, he thought about it carefully, and then asked, "What is in this book...... What's the hardest way?"

Pan Long was a little puzzled and asked, "Why do you want to give up the easy ones and make them difficult? Isn't it good to choose an easy path?"

"The easy road is more likely to be walked by others, if you want to choose, choose the most difficult!" Ren Changsheng said categorically, "The old man has lived for more than 200 years, and he finally has a more reliable chance of immortality, of course, he must choose the one with the greatest grasp!"

So he discussed it with Pan Long for a while, and finally decided to choose the most profound part of the book.

Bi Lingkong pretends to be stupid every time she discusses the content of this part, which shows that she will never choose - even if she can't find a suitable path for the time being, she can't choose a path that she can't understand at all to make do.

It's a big deal to change directions and find a road that no one has ever walked.

Anyway, Pan Long has a lot of ideas, and he can study so many in more than a month, and it will take another three years and five years to find a path that suits her.

"She was lucky enough to sell paintings and pick up a figure comparable to Lu Fuzi in the past as an apprentice. With such a good apprentice, is immortality still a problem? Standing in the wind, pigs can be blown into the sky"-these words were said by Lan Lingqing, and when he said this, he seemed to recall some unpleasant past events, and his face was full of unhappiness.

At that time, she had just started her retreat, and Lan Lingqing discussed with Lie Yukou whether her retreat would be successful. Lieyuko imagined what she might do if she failed in retreat.

"I guess she's going to turn into a bird, and then jump on top of the Pan's head, rolling around, and yelling, 'I don't understand those hard things!' and so on—she's asked Wen Chao for favor more than once, and everyone has seen it. ”

Pan Long imagined that scene for a moment, and couldn't help but shake his head, but he couldn't help laughing.

His own teacher is not only strong in force, but also quite accomplished in selling cuteness, and I think he is also specialized in this skill.

Ren Changsheng couldn't do this kind of thing, he could only honestly study the theories in that book, and then summarize and summarize the appropriate path to immortality.

It was painful, and he shivered more than once, tried to take a deep breath for a while, and then said, "I'm going to take a break"—it would take a whole day of rest to recover and continue his research.

He also complained to Pan Long more than once: "What are you writing here? Those strange symbols look uncomfortable, why can't you use simple addition, subtraction, multiplication and division?"

"Simple addition, subtraction, multiplication and division are in the first half of the book. ”

Then Ren Changsheng would show obvious vacillation and hesitation, but after only a while, he would make up his mind again.

“...... No, I'm going to take the hardest path, lest someone else take the lead!"

I have to admit that at least in terms of willpower, he is stronger than Bi Lingkong, Lanling and Lie Yukou.

With extraordinary efforts, by the end of the year, he finally figured out the "strange symbols" and the relevant calculation principles.

When he was finally able to answer the perfect score for the test paper that Pan Long gave him, he couldn't help but rush out of the door and yell at the sky.

"I actually did it! God! Sure enough, the sky lives up to the painstaking people!"

Pan Long really didn't know what to say about this.

"Well, your grades are good, let's start formal college courses next"?

Forget it, it's really not easy for the old man, don't torture him.

Then Ren Changsheng bathed and changed his clothes, and then began the retreat.

Before the retreat, he said viciously: "I will never leave this retreat until I am reborn! Immortality can't be achieved in this way, that's simply ridiculous!"

Watching the stone door of the retreat room fall, Pan Long smiled.

Whether the teacher's side can succeed, he is not sure, but on Ren Changsheng's side, he can definitely succeed.

A person who can force himself to this point, if he does not live forever, who can live forever?
