At this slow speed, Su Mu shuttled through this library for nearly an hour before he noticed that the old man in front of him suddenly stopped.

And when his footsteps stopped, Su Mu's eyes were also raised for the first time, and then he saw that in front of him, there was a light film that was inverted in the shape of a bowl, and within that light film, four stone tablets could be faintly seen standing silently.

Laugh at!

The mutilated old man slowly raised his thin palm, swiped down lightly through the air, and a ray of light passed through his fingertips, and then Su Mu saw that the light film and even the space were torn apart.

"Is this psychic power?"

Su Mu's pupils shrank, staring at the old man's fingertips, and when the light flickered before, he clearly noticed a familiar fluctuation, which was spiritual power.

It's just that the kind of spiritual power fluctuations that emanate from the old man's body are simply countless times more condensed than him.

If Su Mu's spiritual power is a pool of spring water, the old man may be the ocean, and there is no comparison between the two at all.

"He turned out to be a major in mental power"

Su Mu's heart was shaken, but also a little sudden, no wonder he always couldn't detect spiritual power fluctuations in him, it turned out that the disabled old man's major was spiritual power.

This was the first time he had ever seen someone with such strong spiritual power.

The crippled old man didn't know what Su Mu was thinking, he tore the opening, he stepped forward, and gently stepped in, and Su Mu also quickly followed.

Drilling into the light film, the light in front of him suddenly dimmed, and a strange pressure diffused from the front, which made Su Mu's heart slightly cold, and he immediately raised his head and looked ahead.

There, four black stone monuments stood quietly, and that kind of pressure came from the stone monuments!

The black stone stele, standing quietly in the film of light, creeping, like an ancient beast, an amazing evil aura emanated as if nothing, rippling in the air, making people feel depressed.

These four steles were extremely tall, they were all a few points larger than the steles that Su Mu had seen in the library before, and the kind of fluctuations on these steles were also something that those steles had never had before...

"These four stone tablets all possess an extremely powerful martial art, and to some extent, they can be regarded as the strongest martial arts in our Yang Academy except for the Great Dao Immortal Decision. ”

The crippled old man put his hands behind his back, looked at the direction of the four stone monuments with gray eyes, and said lightly.

"These four kinds of martial arts are not ordinary disciples can practice, and in today's Yang Academy, these four kinds of martial arts, only four closed disciples have cultivated the martial arts on the first stone tablet, as for the other three, no one has yet been able to successfully cultivate. ”

Hearing this, Su Mu was slightly moved.

The Yang Academy is also full of talents, but I didn't expect that among the four martial arts, only four people have cultivated one of them.

"These four martial arts are also high and low?" Su Mu suddenly asked.

"If you really want to distinguish the high and low, the martial arts of the first stone tablet are indeed slightly easier to cultivate, the second is slightly more difficult, and as for the third and fourth, they can be regarded as the strongest, and they can be regarded as equal. ”

"And when Yang Tian was raised, he cultivated the martial arts on the third stone tablet, and the fourth... When he first entered here, he didn't succeed in cultivating. The old man said slowly.

"Oh?"

Su Mu was a little moved, the martial arts of the fourth stone tablet was so perverted, even that Yangtian senior failed to succeed in cultivating?

"It's not that he can't be talented, it's that the martial arts of the fourth stone tablet have slightly peculiar requirements for cultivators. ”

At this point, the crippled old man's voice paused, and he seemed to glance at Su Mu more, before he continued: "That kind of martial arts requires spiritual power and spiritual power, and it has not weak attainments. ”

Su Mu's heart sudden.

This... Are you talking about him?

"You take a look first, and then choose a stone tablet martial arts cultivation. The old man waved his hand and said lightly.

"Yes. ”

Hearing this, Su Mu also hurriedly responded respectfully, and then walked forward quickly, his eyes swept to the first stone stele, the stone stele was as black as iron, and on the surface of the stele, four ancient fonts like iron pens appeared.

Earth-shaking fist.

Su Mu stared at the ancient words on the stele, from these fonts, he could feel a majestic sense of rage coming towards him, thinking that this martial arts must be the kind of way that is extremely strong and fierce.

"Is this the martial arts that Mingkong and they cultivate..."

Su Mu's eyes flashed slightly, and he groaned slightly, and then he took another step and walked towards the second stone stele.

On the second stone stele, a dark long sword was carved, and on the long sword, the starlight was shining, and a kind of cold aura seeped out, and even Su Mu felt a chill on his skin.

Star Pole Swordsmanship.

It's a simple four words, but it's cold.

This martial art is slightly different from the previous earth-shaking fist's extreme fierceness, but the cold chill is like a maggot on the tarsal bone, making it impossible for people to dodge.

Su Mu stood in front of this stone monument and muttered for a long time.

To be honest, he was very interested in this set of Star Pole Sword Technique, because his weapon was the Chiba Sword, and this set of Star Pole Sword Technique was just right for his light sword cast.

He hesitated for a moment, then shook his head.

Although this martial arts is good, it is too cold and not suitable for him, so let's take a look at the rest first.

Immediately, he did not procrastinate, and turned around again, walking towards the third stele.

The third stele is much more simple than the first two, and its color is also inclined to dark gray, on the surface of the stele, there is a figure sitting on the tablet, but the body of the figure is a kind of cracking, looking like a dry earth.

But faintly, in this kind of devastation, there is an amazing sense of power emanating from it.

Su Mu stared at the figure, then raised his gaze slightly, and saw three ancient fonts on the figure pattern.

Innate Dao body.

The name is unpretentious and unfancy, but it has an atmosphere of its own.

"Is this the martial arts that the Yangtian senior chose..."

Su Mu pursed his lips, but his brows were a little furrowed, this innate Dao body should also be a kind of body refining martial arts, which is obviously a bit of a hedge for Su Mu, who has a small barren scripture.

Now he has to consume a lot of energy just to cultivate the Little Desolation Sutra, and if he is distracted from cultivating another body refining martial arts, I am afraid it will be difficult to achieve it.

From what the crippled old man said before, Su Mu knew.

This innate Dao body is considered to be among the best among the four martial arts, and only the fourth martial arts that have not yet met can be compared to it.

From this, we can also know the power of this martial art.

But, Su Mu has a little barrenness...
