The library building of Qianluan Peak is huge, more precisely, it is a symmetrical central axis, square and strict building complex, which is roughly divided into five parts: the library pavilion, the Wentian pavilion, the stargazing pavilion, the secret realm pavilion and the lock demon tower.

Among them, the library is the main body. The Wentian Pavilion and the Stargazing Pavilion are separated from the left and right in the front row, facing each other in the east and west, while the Secret Pavilion and the Lock Demon Tower are in the back row.

Shen Gonghuan attaches great importance to the library building.

In order to prevent unscrupulous people from breaking in, he also set up many magic circles to take care of them.

These magic arrays were more than ten times more sophisticated than the 'Mixed Yuan Heavenly Dou Array' set up by the Blue Wave Fairy in the Qingquan Pond.

If someone who doesn't know what is going on dares to trespass, there is no possibility of retreating.

Lin Zilong grew up in Qianluan Peak with his master and brother since he was a child, and he and his brother have always been able to enter and exit the library at will.

Wentian Pavilion is almost Shen Gonghuan's study, a place where he meditates and writes books.

Although Lin Zilong doesn't bother often, he is still very familiar with the arrangement of the magic circle in between.

Lin Zilong led Gu Ning'er all the way to the Wentian Pavilion of the Library Building, the main body of which is a two-story ring building, which is a relatively small one among the many units of the Library Building.

In the ring building, the first floor displays some literary and historical books after Kunpeng's death.

There are personal biographies, historical records of sects and countries, and even some of the mental journeys of the exercises when they were cultivated to the Great Perfection.

These histories are grouped by type of record.

However, if there are some achievements in the past thousands of years, whether it is an individual, a country, or a sect, you can find some information here.

But I didn't find any information about soul cultivation.

It seems that as Gu Ning'er said, soul cultivation has been extinct for thousands of years, just like that demon.

So he invited Gu Ning'er to go to the second floor together, but Gu Ning'er insisted on not going, her cultivation had reached the peak of the Xuanyuan Mirror, and she came here to get some experience in breaking through to the Lingtong Mirror.

Lin Zilong didn't force it, and came to the second floor of Wentian Pavilion alone, where some more distant historical materials and some secret mysteries were collected.

After some searching, Lin Zilong finally found a few books mentioning soul cultivation in a quaint bookcase in the corner.

Lin Zilong learned from the book that soul cultivation was very common in the Tianhong Continent, and after a soul cultivator reached a certain realm, he could forcibly ingest the soul of a person or demon beast into the 'Soul Palace', and then analyze the soul element by devouring the soul element, and then use the excess soul element to condense and sublimate the 'soul sea' in a place now called the Spirit Sea.

At the same time, outside the body, the 'Soul Refining Furnace' is used to refine the divine soul into the 'Soul Refining Pill'.

By taking the 'Soul Refining Pill', you can hoard the soul element in the dantian, and what flows away from the soul cultivation meridian is the soul element.

Soul cultivation is an almost barbaric primitive cultivation method, and although it works extremely quickly, it has great limitations.

When the soul cultivation reaches a certain level, it is subject to the speed of the formation of the 'soul sea', and then devouring the divine soul will accumulate in its own 'soul hall', and if its own 'soul hall' and divine soul are not big enough, it will be counterattacked.

At that time, the cultivation will be stagnant, and it will be difficult to continue to climb upward, so although the speed of soul cultivation is fast, the upper limit is extremely low.

When Kunpeng Dao Ancestor founded the Dao Method, he used the introduction of spirits into the body as a means of cultivation, and demonstrated his supreme supernatural powers for hundreds of years.

Monks who pursued perfection changed their ways to become spiritual.

Moreover, through practice, the path of spiritual cultivation is relatively gentle, and it is not limited by the size of the 'Soul Palace', although the effect of soul cultivation is not as obvious in the short term, but in the long run, it can climb to a higher realm.

Later, with the birth of Xuanzu and Dao Ancestor, the order of the world was further improved, and the barbaric and primitive cultivation method of soul cultivation became less and less acceptable to the world, and over time it disappeared.

However, there is one exception to all of the above about soul cultivation.

This soul cultivator is called the soul leader, that is, the demon mentioned by Gu Ning'er, he can be very strong, powerful to an outrageous degree.

He is the only person in history who has broken through the limit of soul cultivation, and it is said that his 'soul hall' is a huge spatial enchantment that can hold a huge divine soul like a star, so he can devour other divine souls unscrupulously without being counterattacked.

However, Lin Zilong faintly felt that what was mentioned in the book was only the result, and the reason for this was that the soul kui was different from other soul cultivators, not only because the soul kui's 'soul hall' and divine soul were already very huge, but he also had a place that was different from ordinary people, that is, he had one more meridian, and these two meridians would be called 'soul veins'.

The 'soul vein' can connect the 'soul sea' with the 'dantian', so that its 'soul hall' and the outside world form an effective pathway, this path makes the excess divine soul produced after devouring the soul of others will not be stored in its own 'soul hall', but can be used through the dantian and then radiated from the meridians.

Therefore, he gained the time to expand the soul hall and grow the divine soul, and slowly accumulated praise, and finally obtained the capital to break through the restrictions of soul cultivation.

......

Enjoying the cultivation speed of soul cultivation without being limited by the upper limit of soul cultivation is really a perfect cultivation method.

This kind of cultivation method made Lin Zilong admire, but he was extremely depressed.

Because this method requires a large amount of other people's divine souls, but his cultivation is obviously not to the point of controlling the 'soul hall' to ingest other people's divine souls.

"Could it be that this kind of cultivation method is not suitable for me?"

Lin Zilong thought for a while, and finally had an epiphany, since he also has a soul vein, and the soul vein is connected to the dantian and the location of the soul sea, does it mean that he can absorb the divine soul through the dantian?

Thinking of this, Lin Zilong quickly returned to the first floor, pulled Gu Ning'er and walked out.

Gu Ning'er was looking at the rise, and when she saw that she was going to move the place, she was a little unhappy and asked, "Where are you going?"

"Trial Peak!" Lin Zi's voice was a little excited.

......

Trial Peak is the largest mountain in the Xuandao Sect, during which a large number of demon beasts are kept in captivity for disciples to hunt and hone their combat skills.

Although the demon beasts of the Trial Peak are not particularly powerful, with Lin Zilong's cultivation, they would not usually come here.

Today, with Gu Ning'er as his company, he can finally enter the periphery of the Trial Peak.

Not long after entering the periphery, a clouded leopard appeared in front of him, this is a first-level demon beast, barely enough upper demon beast, but it is the weakest existence.

"Little sister, do me a favor, help me catch it, remember to keep it for a while. Lin Zilong said leisurely.

Gu Ning'er was stunned when she heard this, and just wanted to talk back, but Lin Zilong said again: "Don't forget, you promised me to drive me for a month." ”

Gu Ning'er could only swallow her anger when she heard this, who told her that there would be more things to point at the thief in the future.

Besides, with Gu Ning'er's cultivation, a mere clouded leopard was not taken into account at all, and it was injured and dragged to Lin Zilong in a few back and forth.

Lin Zilong looked at the dying clouded leopard in front of him, stretched out his hand and pressed it on its head, feeling its demon soul carefully.

As soon as Lin Zilong's dantian was inhaled, the clouded leopard demon soul was sucked into the dantian along the meridians on Lin Zilong's hand. Then he contracted the soul elements in his body, and compressed the clouded leopard demon soul in this dantian along the soul vein towards the soul sea position.

Lin Zilong condensed his divine sense and entered the soul sea position again to observe carefully, only to see that after the clouded leopard demon soul entered the soul sea position, a greater suction force came from the direction of the soul hall, and the demon soul was sucked directly into the 'soul hall' by this irresistible suction.

The weak clouded leopard demon soul was like a corn falling into a volcano, and after a while, it could no longer feel its breath, but turned into a little ghost fire floating out from above the soul hall, and slowly leaned towards the location of the soul sea.

I see!

Seeing this scene, he finally solved the mystery in Lin Zilong's heart: "In recent days, the inexplicable ghost fire in the body is the soul element, and these soul elements are actually refined by the soul of the ghost king being devoured. ”
