Obviously, he was aware of Lin Mu's precaution and vigilance, but Yuan Lingzi didn't care. Before the matter was explained, Lin Mu's attitude towards the head and elders was indeed very respectful and grateful, but now......

To put it simply, the relationship between Lin Mu and the Lingxu Sect is already a cooperative relationship. His hole cards are seven bone fragments. The importance of this, as well as its special significance, is something that the Lingxu Sect cares about very much.

The change of attitude is inevitable, and in the same position, there is no need for Lin Mu to continue to grovel. At least for a short time, Yuan Lingzi didn't dare to touch him. Besides, they were all very clear about the previous promise made by the Lord of the Dragon Xuan Palace.

Yuan Lingzi also knew that he couldn't be in a hurry, after all, Lin Mu had just fought a big battle, and it was impossible to recover quickly. And without reaching a certain realm, it is impossible to comprehend the white bone fragments.

In other words, Lin Mu still has at least a lot of use value. No matter how angry Yuan Lingzi was, he didn't dare to touch him at all, and no matter what cultivation resources he wanted, he had to satisfy him as much as possible.

On the new day, Lin Mu still saw no one, including the Great Elder who had been trying to explain something. He locked himself in the deepest part of the library, constantly flipping through the books, what he had seen before, and what he hadn't touched.

Wandering in the sea of classics, Lin Mu realized that the collection of the Lingxu Sect is simply everything, worthy of being a large sect, and the background is not ordinary. So he watched it even more fascinated, and even forgot to sleep and eat.

Everyone understands the truth that if you want to hurry, you can't reach it, but Lin Mu doesn't have too much time. The situation seems to be stable now, but maybe when, the major sects of the Imperial Spirit Zhongtian can't bear it anymore and point the finger at this side?

Now you can also take advantage of a series of events that happened in the Holy Lord's ruins to point all the contradictions to the Hades Palace for the time being. For a while, at least, the Ghost Society was in a troubled situation.

But the darkness will solve the problem in a short period of time, and spread out the key problems. Lin Mu held the white bone fragment in his hand, that is, the holy bone trace that all cultivators were eager to follow, so would the Spirit Void Sect still be able to keep him?

Therefore, we must take advantage of the fact that now, Lin Mu will enrich his hole cards, and his strength must be improved as much as possible. No matter what kind of whispers the sect will have, it can't be controlled so much, I believe that the elders will have a way to suppress it.

Constantly flipping through the classics, first of all, the exercises. But after having the Holy Ancestor Sutra, Lin Mu could no longer cultivate anything else. So you can only focus on spiritual skills. In this library, there are thousands of spiritual skills.

Lower, medium, top, best. Lin Mu didn't want to ascend to the sky in one step, whether it was the Spirit Breaking Finger or the Spirit Breaking Sword, it seemed that now it was just a low-grade spiritual skill, so the best spiritual skill could not be touched, and the high-grade one could be tried.

Tian Yuan Gang Qi, Thunder Python Flying Scales, Yuan Ling Sword Technique. None of these existences are what Lin Mu wants. So the books were lost. After a long time, about an hour later, Lin Mu's footsteps finally stopped.

His gaze was fixed on a box, and on top of it, a powerful spiritual power barrier was surrounded. That fluctuation is not something that ordinary people can touch. It seems to be a very strong sealing power.

"It's ...... What?" Lin Mu stretched out his hand, tentatively trying to touch. But in the next second, a backlash surged, shaking him away. At that moment, Lin Mu seemed to feel a familiar aura.

"No wonder... This seems to be the fusion of the three forces of ice, fire, thunder, and forming, forming the strongest seal. It seems that the spiritual skills contained in this box should be quite powerful, but I want to see what it is. ”

Originally, Lin Mu had the power of thunder and fire, and as for the cold and ice qi, he was not unable to resist it. But the spiritual root in the dantian mutated and was devoured by the ancestors without authorization, and after losing this power, he was really struggling now.

However, just as he hesitated, a wave suddenly appeared. Lin Mu's heart moved, and his eyes lit up: "Hehe...... How did I forget about you. You're my old buddy, that's not a problem. ”

With a flip of his right hand, a flash of light flashed. As soon as he grasped the palm of his hand, he saw a spirit bone appear, and strong fluctuations flashed on it. Lin Mu's mind turned, and the Kaiyuan spirit bone turned into the size of a brush. Lightly dot on top of the box.

The surge of spiritual power, coupled with the diffusion of divine consciousness. The runes on the Kaiyuan spirit bones flickered in an instant. A terrifying phantom appeared, only to see it open its huge mouth and pounce fiercely forward.

The roar of the beast shook the entire library building. This devouring power quickly broke the power of the seal on the box, and the breath dissipated.

"What a temper. Man, I know I haven't had time to take care of you during this time, so you have a complaint in your heart, right? But I also know your feelings, I'm really sorry, I'll pay more attention to it later. ”

As if he understood, Kaiyuan Spirit Bone trembled and disappeared into Lin Mu's hands. And the box in front of him, after unlocking the blockade, slowly flew up and froze in front of Lin Mu. The latter reached out and tapped lightly.

A mysterious force slammed into Lin Mu's eyebrows, and the complicated cultivation method appeared in Lin Mu's mind in an instant. Such an impact made Lin Mu subconsciously retreat and gather for a while.

"Soul Building, one of the three treasures of the Lingxu Sect's library. Cultivators can increase the strength of their spiritual power as they like under certain circumstances. However, it can only be cast three times at a time. After three times, the cultivator will fall into a period of malaise. ”

This is the case with the record in the vast message. And no matter how Lin Mu sorts it out, the only important keyword that can be found is this. No more. So he was at a loss, how should he cultivate?

There was no physical jade slip, and there was nothing to write about the cultivation method of spiritual skills, just a stream of information entering the divine consciousness. Such a special existence, Lin Mu is the first time to encounter it, it is really troublesome.

"Spiritualism, huh? I'd like to see how subtle you can be. ”

Sitting cross-legged, Lin Mu's hands were sealed, and a light flashed at the center of his eyebrows. Raise your consciousness and wander in the space of your consciousness. The information he had just entered was completely fused with his divine consciousness space, and there were traces everywhere.

"I see, the so-called spiritual building technique is actually a spiritual skill that assists spiritual power with special auxiliary spiritual power. When casting a means, it can be amplified to a certain extent. A spiritual explosion, combined with spirit building, can increase the destructive power of immense. ”

Finally touching a little way, Lin Mu inadvertently seemed to find an existence between spiritual skills and exercises, and he couldn't fully understand it in a short period of time. So he has to stay in this library for a while.

When the mark on the Soul Building Technique box was broken, Yuan Lingzi sensed it in that instant. His eyes opened, and a burst of essence burst out: "This kid, is it too much?

At the same time, many elders also noticed unusual fluctuations. Streamers flashed one after another, and they all headed towards the library. However, on the periphery, the powerful Spirit Void Sword Qi made it impossible for them to get close.
