After knocking the Black Wind Demon King unconscious, Lin Yu took out a few spiritual coins, which were sealed with forbidden spells, sealed the big demon to death, and then sent it to the two little demons of Liuer and Clam Changsheng to guard.

"Take a good look at this rhinoceros spirit, he is a demon king all the way, since he is guarding Xiong Batian, then, there must be some responsibilities in him, we only need to stay here for a few days, and someone will definitely come here again." You can help me get some news out of his mouth by the way, as long as you don't kill him. ”

Lin Yu commanded cleanly.

"Good!"

Clam Changsheng and Six Ears were eager to try, lifted the body of the Black Wind Demon King, and returned to the hut in the medicine garden.

Lin Yu, on the other hand, stayed in the medicine garden, idle, checking the signs of the growth of the elixir here, and soon, there were some discoveries.

When he was leaving, he had taught Xiong Batian the entry-level elixir cultivation method of "Notes on the Grass Hall", originally, this stupid bear only knew how to cultivate human-level elixir, but now, the garden has been planted with ground-level elixir, obviously he has learned something, and has grown a lot.

"The elixir here is still growing, it seems that someone should cultivate it regularly, if nothing else, it should be Xiong Batian. Lin Yu muttered to himself.

He observed very carefully, and after analyzing it, he could only come to such a conclusion.

You must know that among the demon beasts, there is no one who knows how to grow elixir. And the demon who can cultivate the earth-level elixir is even more rare in the world, except for Xiong Batian, he really can't think of any other explanation.

According to the information obtained, Lin Yu already knew that the changes in the eighteen mountains of Lingnan were caused by the ten demon kings led by the Swallowing Gang Demon King, the Barrage Demon King and the Kaishan Demon King. It's just that he still doesn't understand why these big demons did this, and where Xiong Batian and Hu Susu went.

Thinking of Hu Susu, Lin Yu couldn't help but recall the beautiful scene in the medicine garden that day, and it was that time that he not only spied on the other party's memory, but also secretly learned the secret art of the Thousand Illusion Maze.

"Unexpectedly, the wilderness is getting more and more chaotic, and I don't know who is behind it. For now, it seems that this is the only way to go. ”

While Lin Yu was silently muttering to himself, he raised his feet and walked towards Fuli Mountain, and after a while, he came to the place where the spiritual veins of the ground steps hidden deep in the mountains were located.

After a few months of absence, when I returned to this place, this spiritual vein had changed slightly, as if it had been partially consumed, and it was visible to the naked eye that it had become a little smaller.

Lin Yu was not surprised, cultivating a ground-level elixir was bound to use a large amount of aura, which should have been collected by Xiong Batian like this.

"Let's try to hit the last level of the soul cultivation period first, as for the ice crystal fruit, wait until you find Xiong Batian, and then hand it over to him to cultivate......"

With such a plan, Lin Yu directly bent down and meditated directly below the spiritual vein.

He closed his eyes tightly, calmed down, and in a short moment, he entered a realm of forgetting both things and himself.

In my mind, the light blue crystal-like soul flickered regularly as if it had been sensed by something.

"The spiritual veins of the earth level, the formation of the aura of heaven and earth, among them, there is also a soul of heaven and earth, although it is weak, but it is real, I only need to communicate with this soul to strengthen the soul!"

Between his thoughts, Lin Yu had already settled down, and he couldn't sense anything in the outside world, although his eyes were closed, but the veins and trajectories of the earth-level spiritual veins were floating in front of him.

Pure white aura, like the pulse of a person, came from all directions between heaven and earth, and finally converged into a river and appeared in front of you.

In the midst of these countless veins, there is also an extremely subtle aura circulating, which is not an aura, but it echoes with heaven and earth, controlling the operation of all aura.

This is the so-called soul of heaven and earth!

The so-called soul of heaven and earth is not a kind of substantive soul or aura, but a trajectory, a kind of truth, and it is with this kind of thing that the aura will gather and gradually form a spiritual vein.

The human-level spiritual veins also have this kind of heaven and earth soul circulation, but it is already so weak that it is imperceptible.

The earth-level spiritual veins were more abundant, so Lin Yu could only detect them when he was concentrating. In the same way, the Heavenly Rank Spirit Vein and the Soul of Heaven and Earth will be even richer, and it will not be so laborious to communicate.

Sensing the existence of the soul of heaven and earth, Lin Yu no longer hesitated, and used his mind to control the soul in his mind, and gently operated according to this trajectory, and soon, it began to take shape, and the soul had some changes.

"It really works......" he sighed inwardly.

Originally, the cultivation of the soul was to meditate and contemplate every day, or bathe in incense, so as to slowly strengthen the soul and break through the soul cultivation period and the distraction period. And now, Lin Yu uses his soul to simulate the trajectory of heaven and earth, this way seems to be unremarkable, but it has an inexplicable effect, so that the soul begins to grow continuously.

In fact, there are deeper reasons why his progress has been so fast.

Losing the seven emotions and six desires also means losing all kinds of miscellaneous thoughts, and his soul will become much purer, and his thoughts will be firm, and when he cultivates, his speed will be much faster.

Of course, this does not mean that it is a good thing, the lack of soul is equivalent to the possibility of immortality. With incomplete soul cultivation, at most you can cultivate to the highest level of the Spirit Realm, the Soul Wandering Great Thousand Realm, you will no longer be able to cultivate.

If you want to break through the Yuan Shen Realm, you must have three souls and seven spirits intact, otherwise, even if you are as poor as possible, you will not be able to break through.

This is also the fatal part of the Xuanmen Immortal Cultivator, before the achievement of the Yuan Shen, once the soul is damaged, it will never be able to live forever.

There are no years of cultivation, and three hours are spent unconsciously.

At this time, Lin Yu suddenly opened his eyes, stood up, and stopped cultivating. After this meditation, he successfully broke through the soul cultivation period and reached the last level of the mana realm, the Dividing Period!

The distraction period, that is, after the soul has grown, it is necessary to start trying to distract the thoughts and multitask.

Serious Xuanmen monks, whether they are chanting mantras or pinching mantras, need time and effort to do it, and even more so monks who study spells or spells. In the midst of the battle, it is often necessary to recite spells and pinch spells to cast powerful spells.

An outlier like Lin Yu is, after all, a minority. Therefore, the realm of the split mind period is to constantly scatter the thoughts until you can use five uses of one mind and perform five spells at the same time, and then you can be regarded as having arrived at home.

Only by practicing the sub-contemplation period to perfection can one have the qualifications to impact the spiritual realm.

"In the future, if necessary, I must go to the Netherworld to retrieve my missing soul, otherwise, there will be no hope of immortality in this life......"

After finishing his cultivation, Lin Yu stood up, looked at his hands stupidly, and muttered to himself.
