Before leaving, Ye Fan specially sent a spiritual piercing to the second senior sister Su Wanshui, asking her to answer the third senior sister, so that she would not be able to find the Guantian Cave.

Ye Fan stayed alone in Xiaoqiongfeng to deal with relevant government affairs.

When he is okay on weekdays, Ye Fan meditates, cultivates steadily, and sometimes deals with government affairs.

Ye Fan found that since the end of the retreat in the Guantian Cave, his cultivation had completely stagnated, as if he had encountered a threshold, and he felt that no matter how he cultivated, he would not be able to break through the middle stage of foundation building, which was something he had never experienced in the previous Qi Cultivation Realm.

"Could this be the so-called bottleneck period?" Ye Fan said to himself.

For other immortal cultivators, they will encounter a bottleneck period as early as when they are practicing the Qi realm, those with average talent will encounter a bottleneck period in the third layer of Qi training, and those with better talent will encounter a bottleneck period in the sixth layer of Qi training, and those with outstanding talents, such as Lin Hongxue and Song Tianming, will also encounter a bottleneck period in the ninth layer of Qi training.

Like Ye Fan, there is no one who has encountered a bottleneck until the foundation building realm.

Of course, Ye Fan was able to ascend to the ninth level of Qi Cultivation in one go, all by virtue of the Ascension Pill, so there was nothing to compare.

If he can't break through the middle stage of foundation building in a short period of time, Ye Fan simply no longer thinks about the breakthrough time, and when the water is a matter of course, he will naturally break through, and now he can't rush it.

On this day, Ye Fan suddenly thought of the ancient text that was rubbed down from the Guantian Cave.

Because he had been in retreat for more than half a year, coupled with the meeting with Wu Tian, he forgot about the ancient text.

However, now that he thinks about it, Ye Fan must find out.

I saw Ye Fan's template printed in the dark, and then wrote down these ancient texts word for word.

With Ye Fan's talent, memorizing these words is something that has been read several times.

Soon, Ye Fan wrote down these ancient texts word for word.

Afterwards, Ye Fan went to the Hidden Scripture Pavilion of the Divine Sword Gate.

Each sect has a scripture pavilion, which is used to collect all kinds of ancient books and exercises.

Ordinary literature and ancient books can be borrowed casually, but the Gongfa classics need to be allowed by the elders of the Tibetan Scripture Pavilion, and they generally need to make a certain contribution to the sect.

Ye Fan didn't need to borrow the Dharma classics, so he didn't need to make any contributions.

The Tibetan Scripture Pavilion belongs to the Divine Sword Blade Sect, and is personally in charge of the Chen Sect, after all, the exercises are the cornerstone of a sect, and there is no room for the slightest mistake.

Now the head of Chen is in retreat to heal his wounds, and according to the rules of the Shendao Gate, he is jointly supervised by the head of the Song Dynasty, Elder Guan, and Elder Wu.

What Ye Fan borrowed was an ordinary literature and classics, and it did not involve exercises, and Ye Fan himself was the master of a peak, not an ordinary disciple, so he didn't need special approval to enter the Tibetan Scripture Pavilion.

Ye Fan came to the library of literature and classics, and there were millions of books in it, from the Yao Shun era, to the war of the Seven Kingdoms, and then to the Qin Dynasty to dominate the world, and then the Han Gaozu beheaded the white python, the rule of Zhenguan in the Tang Dynasty, and finally the Song, Liao, Jin, Ming and Qing dynasties and so on.

It can be said that the documents in it record the history of the civilization of cultivating immortals in various dynasties.

"Senior Sister said that it is a long-lost text, and it seems to be of a special race. Ye Fan said to himself secretly.

Subsequently, Ye Fan began to purposefully consult these classics in the Scripture Pavilion.

These classics are arranged in chronological order, Ye Fan directly found the ancient books of Yao Shun and the era of the Seven Kingdoms War, and then carefully flipped through them.

Before the Qin State, there were thousands of kinds of writing, and after the Qin State unified the world, the writing was unified.

Therefore, there are many texts that record the history of Yao Shun and the Seven Kingdoms of cultivating immortals.

Ye Fan didn't know those words, but fortunately, some people in later generations repaired the translation under the original model text, which is the common language of later generations, so it is not difficult to read.

Ye Fan glanced at ten lines, and basically read the entire page at a glance.

"No, no, it's not ...... yet"

Ye Fan flipped through them one by one, but there were hundreds of them with a face, and there were no relevant records.

"Where is it?" Ye Fan frowned, and couldn't help but release the Yuan Shen while flipping through a number of ancient books.

After all, from Yao Shun to the Warring States Period, there were sixty or seventy thousand books, and I looked through them one by one, and I didn't know when it would be.

I saw that Ye Fan's Yuan Shen swept over the hundred ancient books at once, and almost instantly, he finished reading the contents of the hundred ancient books.

"Not yet, it's not fast enough, it has to be faster. Ye Fan said secretly.

Then, I saw Ye Fan frantically urging Zhenyuan, from the initial reading of a hundred books at the same time, to two hundred, three hundred, five hundred, and all the way to eight hundred.

Flipping through eight hundred ancient books at the same time is already Ye Fan's limit, and no matter how fast he is, his Yuan Shen can't bear it.

However, this speed is already quite okay, and sixty or seventy thousand books are only a little effort.

"Huh?"

Suddenly, Ye Fan stopped, only to see him walk quickly to a bookshelf, and then pull out one of them.

This ancient book is very ancient, wrapped in cowhide on the outside, and the binding line is also inlaid with gold, which looks different from ordinary books, only to see four ancient Chinese characters written on the cover, "Spring and Autumn Records".

Ye Fan didn't care about the cover, but turned to one of the pages very quickly, only to see that page was written '劎'.

There is also a rubbing template for this word, and the senior sister said that this is an ancient word, a sword.

Ye Fan carefully read this page, only to see that it read: "The word 劔 is orthodox, created by the sword cultivation clan, and in the same year, there was also a word 'sword' with the same meaning.

However, the sword character was not created by the sword cultivators, but by an immortal cultivator named Wuji Sword Immortal, who relied on his own sword cultivation to create this 'sword' character.

Later, for some reason, the sword cultivation clan suffered a catastrophe, and all the words and exercises in the clan were all cleared, leaving few words.

Seeing this, Ye Fan couldn't help but pause, "Could it be that the words in the Guantian Cave are the ancient characters of the Sword Cultivation Clan?"

Stunned, Ye Fan came back to his senses and continued to look back.

However, the record of the sword cultivator clan is a glimpse, except for the word '劎', and there is no other content.

Ye Fan frowned for a while, so he could only put down the ancient books in his hand for the time being, and then continued to consult other ancient books.

Yuan Shen quickly swept through these sixty or seventy thousand ancient books, but only that one appeared in the sword cultivator clan, and the other ancient books did not have any records.

Ye Fan was helpless for a while, according to the records of the Spring and Autumn Period, the Sword Cultivation Clan should be a very inconspicuous small clan in the Yaoshun period.

Otherwise, they will not fall into the fate of extinction.

Ye Fan looked at the remaining more than 900,000 books, thought about it, and decided to read them all, maybe there would be relevant ruins of the Sword Cultivation Clan found in the future.

Subsequently, Ye Fan released the Yuan Shen again and flipped through the remaining ancient books one by one.

After reading two or three hundred thousand ancient books in a row, Ye Fan only felt that the Yuan Shen was getting more and more tired, and the efficiency of flipping through it had also dropped significantly, so he couldn't help but stop for the time being.

Then, I saw Ye Fan turn over his palm and take out a Divine Cultivation Pill, and then rest on the spot.
