A pair of eyes full of aura slowly opened, after nearly five years of hard work, Lin Song finally entered the late stage of foundation building, and the difficulty of cultivation was far beyond Lin Song's imagination.

There are thirteen major stages for immortal cultivators, namely

Foundation building, grain refining, consecration, fusion, heartbeat, spiritual silence, primordial infant, out-of-body, distraction, integration, opening the heavens, Mahayana, Qiankun.

And each big stage has three small stages, which are the first, middle and last phases.

After Lin Song obtained the star bone, although the star bone itself had the ability to absorb the aura of heaven and earth, Lin Song's cultivation was equivalent to cultivating all the time, but the energy required for each stage was countless times higher than that of ordinary immortal cultivators.

And the star bone has the master, and the mysterious saint who has become crazy in scientific research naturally has to study it carefully.

According to the research data of the Xuanji Saint Venerable in the past few years, if Lin Song wants to complete the foundation building and enter the rotational illumination, the aura he needs is comparable to that of the immortal cultivators of the Spirit Silence Realm.

This aura is not volatilized, but saturated, so it has to move on to the next stage.

Theoretically, Lin Song's current state can rival that of an immortal cultivator in the Heartbeat Realm, but he is just a bear child in the Foundation Realm, which really makes Xuanji envious.

Fortunately, Lin Song is also half of his apprentice, which makes him feel a lot better.

After leaving the Library Pavilion, Lin Song left a letter for the administrator and then took the Xuanji Holy Venerable to the front of the small hill.

And for Lin Song, this was quite risky, because he didn't have any means to compete with the Xuanji Saint Venerable.

There was no way, Lin Song could only put the knife on the neck of the dog of the Xuanji Saint Venerable, but the Xuanji Saint Venerable was angry.

At this time, Lin Song knew that not everyone could enter this stone room, and only those who met the conditions could enter, so when Xiaobai entered for the first time, it could make the Xuanji Holy Venerable depressed.

This stone chamber is not just a stone chamber, but a small world of the Xuanji Holy Venerable, and the stone chamber is only specially built to better absorb the aura of the Qiankun realm and the aura outside the Qiankun realm.

Originally, the stone door behind the constellation of stars and bones was opened, and there was something else inside, not only landscapes and trees, but also various ancient demon beasts, like an independent Qiankun world.

Although this Xuanji Saint Venerable is not good at all kinds of lethal martial arts, he enters the Tao with alchemy, supplemented by refining weapons, and assisted by refining talismans, and sets foot on the road of cultivating immortals.

Because Lin Song didn't know what his Tao was, he could only learn from alchemy by drawing a gourd scoop.

After five years of study, the Xuanji Holy Venerable has strengthened his determination to accept Lin Song as an apprentice.

In the eyes of the Xuanji Holy Venerable, Lin Song's talent for alchemy, talisman making, and refining far surpassed that of his former self, which made the Xuanji Holy Venerable's heart bloom.

Due to the needs of alchemy refining tools, I have only learned fire techniques in five years, and martial arts have only learned two moves, although the power is good, but it is a little monotonous.

However, I learned a lot of small spells, and even combined with small spells, I drew inferences from each other and made all kinds of unserious little spells to make Xuanji cry and laugh.

"Xiaobai, this stealing space is almost closing."

"yes, it's time to get out"

For the title of Xiaobai, Lin Song has been called like this for five years, and the Xuanji Saint Venerable has become accustomed to it, and at first he would ask Lin Song to correct it, but later he felt that this title was not bad.

The space that Lin Song is in now is called the space of stealing time by the Xuanji Holy Venerable.

After using it once, you have to wait 10 years before you can use it again.

This is a super secret treasure that Xuanji exchanged for his life back then.

There is a compass at the entrance of the space, on which an energy bead accumulates every ten years, and consumes one every time it is used.

Although the compass was covered with circles of energy beads, it was a pity that Xuanji said that it could not be used.

This stealing time space can be fast or slow in external time.

For example, six hours in space, five years outside the space, or six hours outside the space, and five years in the space can be freely converted, which is very magical.

A man and a dog have just walked out of the black hole-like entrance of the stealing space.

The entrance began to spin, shrinking from its original size of about two meters to disappear, leaving only the compass that showed circles showing energy.

After the time space disappeared, Lin Song actually had a feeling that time was going backwards.

"I'm not going to leave here, I'm going to study how to cultivate a human form, you have already refined this Qiankun Realm and you can take it with you, you can use the things here as you like, if you have difficulties, call me"

Xiao Bai didn't say much superfluous, smashed his mouth and said with some pain, after all, this is all his collection since he practiced, and the Qiankun Realm is an independent world that he has cultivated for thousands of years.

But there's no way, you can't take the mysteries here with you.

It is impossible for him to stay in this place as a dog, and the life span of a dog is only ten years.

Even with the elixir, he didn't have the confidence to get a glimpse of the demon cultivation method in the past ten years.

After all, in the past five years, in addition to teaching Lin Song to cultivate, he has also consulted a large number of books to get a glimpse of the demon cultivation method, but he can't get started.

Instead of letting his things become ownerless from now on, it is better to let him help his inheritor to explore the pinnacle of the Dao.

I have to say that the richness of the collection of this powerful immortal cultivator who has lived for thousands of years is not comparable to ordinary people.

Just the collection of books, Xiaobai has only seen the tip of the iceberg in the past five years, and every time he takes out the books, he can cause a bloody storm in the rivers and lakes.

"Okay, I'll go to the outside world to help you find out."

Lin Song responded

"It's rare that you stinky boy have this heart, but don't leave this alchemy behind outside, this pill I taught you is definitely not an ordinary thing"

As if entering a memory, he continued with a slight pause

"This Dan is decided..."

It turned out that this set of Dan was obtained when Xuanji was a child, and Xuanji was just an ordinary person at that time.

By chance, he got three secret books.

Helplessly, only this Tianyan Dan can definitely get a glimpse of one or two, and the other two Tianyan Instrument Decisions and Tianyan Fu Decisions can only be learned after entering the Dao.

As for the origin of these three sets of secret methods, Xuanji does not know very well, but after a long period of research and comparison, Xuanji Shengzun found that these three sets of secret methods are likely to be the remnants of the ancient gods, but the specific origin is not known.

Lin Song only knew that the alchemy method he inherited from the Xuanji Saint Venerable was called "Tianyan Dan Decision", but he had never heard the Xuanji Saint Venerable say the origin of this set of Dan Decisions.

Therefore, since the Xuanji Holy Venerable was interested in saying that Lin Song naturally listened with great interest, he never expected that this Dan would have such a big origin, although he didn't know what this divine clan was.

"How is the Protoss compared to the Immortal Cultivators?"

Lin Song was very curious and couldn't help asking

"Hehe..."

Xiao Bai paused slightly, and then said

"As far as your current cultivation is concerned, you can't say it," Xiaobai said with a smile, turned around and disappeared.

Lin Song was helpless, but he didn't say much, and after five years of getting along, Lin Song also knew Xiaobai's temper somewhat.

Xiaobai will definitely not say it if he doesn't want to say it, naturally he has his reason, and Lin Song naturally doesn't want to ask more.

As soon as Lin Song's mind changed, he came to the cave where the magic weapon was placed in the Qiankun Realm.

When I first entered the cave, I saw all kinds of magic weapons suspended in the air, and a handle magic weapon was overflowing.

Each piece is a boutique of the best, and every piece that goes to the outside world can set off a bloody storm in the rivers and lakes.

After five years of refining, Lin Song thought that the magic weapons he had refined should be considered high-quality, but when he saw these magic weapons, he realized that he was just a frog at the bottom of the well.

Lin Song was ashamed, but he also strengthened his cultivation heart, and it was worthy of a major repair supplemented by refining weapons.

Although he knew that the magic weapons inside were not all exercised by the Xuanji Saint Venerable, this did not prevent Lin Song from admiring.

Lin Song put away his mood and walked inward with anticipation.

Although there are prohibitions in this cave, for Lin Song, the master of the Qiankun Realm, he can naturally have no scruples.

All the way to the magic weapons, dazzling, continue to deepen, Lin Song has never stopped, now Lin Song has never forgotten, all the magic weapons are at a glance.

It's not that the magic weapons are bad, but I feel that those magic weapons have nothing to do with my current self.

The magic weapon in it is no longer suspended, but is sealed in the stone wall by various materials.

A magic weapon sealed in the jade gave Lin Song a hint of sensitivity, and through the jade, Lin Song saw that it was a golden dragon about thirty centimeters long.

It seemed to feel Lin Song's gaze, and the golden dragon actually opened his eyes and glanced at Lin Song.
