"Demon God Transformation" is a set of emperor-level top cultivation exercises, the Demon Clan's exercises are already extremely domineering, although Gu Yan's cultivation of "Demon God Transformation" has only reached the entry level, but its domineering has indeed been seen.

The surface of the ancient rock body was surrounded by dark black magic patterns, frantically absorbing the pure demonic qi in the depths of the valley, and being nourished by such pure demonic qi, the color of the demonic patterns became darker.

Although "Demon God Transformation" is a cultivation exercise, it is more inclined to the physical cultivation exercise, which has a great assistance for the improvement of physical strength, and the effect is even better than that of the "Great Five Elements Technique".

Gu Yan watched the color of the demon patterns on his body continue to deepen, and his face also showed joy, the reason why he had never focused his cultivation on the "Demon God Transformation" was the lack of high-quality demon qi, although he had harvested a lot of demon cores in the secret realm of Lingzun, but the quality of the demon qi contained in those demon cores was too low, and it could not be used for the cultivation of "Demon God Transformation" at all.

And the demonic qi stored in the Demon Devouring Ring, although the quality is extraordinary and there is a lot of quantity, it has been consumed by the Demon Devouring Ring's own damage, so without the pure demonic qi, the cultivation of "Demon God Transformation" has been stagnant.

Now, seeing the incomparably pure massive demonic qi in the valley, Gu Yan was naturally very surprised, if the "Demon God Transformation" could break through the first change-body skin change, Gu Yan believed that his physical defense would be qualitatively improved, and his strength would also increase a lot.

There are four major realms of "Demon God Change" exercises, which are called four changes: body and skin change, flesh and blood change, demon bone change and meridian change, these four realms are from the inside to strengthen the physical strength of the martial artist, the demon itself is a race with strong physical strength, if you can cultivate the "Demon God Change" to the meridian change, it is enough to make the physical strength of the demon race reach a level comparable to that of the demon clan.

And now Gu Yan's cultivation of the "Demon God Transformation" is still in the first layer of the realm - body skin transformation, in order to break through the first layer of body skin transformation, it is necessary to let the magic pattern cover the whole body, and the demonic energy required to condense a complete demon pattern is almost equal to the sum of the demonic qi origin in the dantian of a demon handsome peak master.

In order to make the demon pattern cover the whole body, Gu Yan preliminarily estimated that at least a few demon cores with strength at the level of the Demon Emperor were needed, but the body and skin transformation was only the first level of the "Demon God Transformation", and the demonic energy required for the flesh and blood transformation and demon bone transformation in the back was even more terrifying.

Therefore, it is difficult to cultivate "Demon God Transformation" to the realm of Dacheng in the Ancient Continent, but Gu Yan only had the mentality of giving it a try at the beginning, but he didn't take too much into account of it, and he didn't have much hope for "Demon God Transformation" at the beginning.

But now the situation is different, the demonic qi in this valley is not only of extremely high quality, but the total amount is not small, if he can absorb it all, it may not be able to allow him to successfully break through the "body and skin transformation".

Feeling the frenzied influx of pure demonic qi into his body, Gu Yan calmed down his excitement, looked at the depths of the valley, and let go of his divine sense with all his might, but because the demonic qi in the depths of the valley was too strong, the suppression of divine consciousness was extremely serious, and the distance of twenty meters was already the limit of exploration.

Gu Yan's right foot slowly stepped away, and cautiously walked towards the valley, the depths of this valley contain such a huge amount of demonic energy, there must be something extraordinary, Gu Yan guessed that this valley should be a demon camp, and the valley is likely to have an extraordinary quality magic stone vein.

The magic stone vein is the same as the barren stone vein on the ancient continent, but the former does not contain pure heaven and earth vitality, but pure demonic energy, the magic stone is the same as the barren stone, it is divided into four grades, but the value of the magic stone of the same quality is much higher than that of the barren stone.

After all, scarcity is expensive, and the value of a low-grade magic stone is a thousand times that of a low-grade barren stone, and it is also a sought-after commodity with no price.

Of course, the existence of a vein of magic stones in the depths of this strange valley is just a guess by Gu Yan, it can exude such a pure demonic qi, and such a large number may also be a top-level magic weapon, but no matter what, for Gu Yan, it is a treasure.

Gu Yan walked very carefully, after all, the range that his divine sense could detect was too small, and this valley was so weird, no one could guess how terrifying the hidden crisis was, and it was always right to act carefully.

After a quarter of an hour's effort, Gu Yan traveled about a hundred meters, and at this time he was already very close to the source of the demonic qi, and suddenly, Gu Yan frowned, lowered his head and looked at his feet.

Just now, his right foot seemed to have stepped on something, Gu Yan slowly bent down, and it was not until he bent down that he could see what he was stepping on, a black metal block, a fragment of a knife-like crystal.

Gu Yan slowly picked up the fragment and gently wiped the soil layer on the surface, a trace of shock flashed in his eyes, and he exclaimed, "It turned out to be Taiwen Gold, the top material for refining Emperor-level high-grade crystals." ”

Gu Yan recognized at a glance the material for refining this weapon, Taiwen Gold, an extremely precious refining material, and it was the best material for refining knife crystals, a fist-sized piece of Taiwen Gold was worth tens of thousands of superb barren stones.

Nowadays, if the refiner wants to use Taiwen gold to refine a king-level weapon, it will be mixed with a small part at most, although it is a small part, it is enough to increase the value of this weapon several times, but this fragment in Gu Yan's hand is all made of Taiwen gold.

A weapon made of a whole piece of Taiwen gold, the level has reached at least the middle level of the imperial rank, and then look at the fracture, it is as smooth as one, you can imagine how terrifying the power of cutting this weapon is.

Sighing slightly, Gu Yan threw the fragment in place, this fragment has been gone through too long, and with such a strong demonic qi in the valley, the Taiwen Gold has been corroded too badly, and it has no great value.

Subsequently, Gu Yan continued to approach the source of demonic energy, and along the way, he also found a lot of weapon fragments, a lot of them, most of which were not of low grade, but the situation was the same as that Taiwen gold fragment, the time to discard it was too long, and the corrosion was too serious, and it had no value.

At this time, Gu Yan was less than ten meters away from the source of the demonic qi, and the demonic qi around the ancient rock was several times richer than before, and the ancient rock divine sense was barely able to detect the source, and then Gu Yan found that this monstrous demonic qi was actually emanating from a cave in front of him.

As for the rock walls around the cave, they were completely eroded by pure demonic energy, and there was a faint glow of ghostly light.

Gu Yan was cautious, and after hesitating for a moment, he decisively took his right foot and walked slowly towards the cave.

Feeling the coercion, Gu Yan's heart trembled, and he poked out his divine sense, and at the same time, the muscles of his right hand tensed, ready to throw the burst bead in his hand at any time.

Suddenly, a strange look flashed on Gu Yan's face, his eyes stared straight at a corner in front of the cave, and the corners of his mouth were surprised, "How is it possible?

Gu Yan's divine sense found that a black elixir actually grew in a corner about two meters away from him, although the demonic aura was very strong, Gu Yan could still feel a faint medicinal fragrance, and Gu Yan had smelled this medicinal fragrance just now.

However, when I think about it, this valley is full of monstrous demonic energy, not to mention the elixir, even if there is not a single barren grass or barren tree, how can there be an elixir to grow.

Gu Yan walked directly towards the corner where the elixir grew, and after Gu Yan got closer, he really saw the true face of this elixir, this elixir was dark all over, there was not a single medicinal leaf, only a black flower on the top, which looked like a peony.

Gu Yan looked at the characteristics of this elixir and searched for some memories in his mind, but none of the elixirs he remembered matched this elixir, and Gu Yan guessed that this was probably a rare elixir that grew in the demon world.

After thinking about it, Gu Yan took out a jade box from the storage ring, and at the same time, a jade shovel appeared in his hand, preparing to put this elixir into the jade box first, seal the spirit talisman closely, and try it in the Void Tower after it goes out.

Just as Gu Yan Jade Shovel dug up the rhizome of the elixir along with the soil and put it into the jade box, a trace of crisis suddenly flashed in his heart, and Gu Yan said secretly, "It's not good, it's dangerous." The figure hurriedly retreated.

As soon as Gu Yan's body stood up, a black shadow "brushed" behind Gu Yan, Gu Yan didn't even have time to put the jade box into the storage ring, his body turned, and the four bursting beads in his hand shot directly towards the black shadow behind him.

At the same time, Gu Yan's right foot kicked the jade box out of the cave, and his figure also flashed out of the hole.

"Boom, boom, boom!"

A series of explosions, a series of violent energy directly rushed out from the mouth of the cave, fortunately, Gu Yan flashed out of the hole and flew straight towards the side of the cave, at this time, Gu Yan stood on an abrupt boulder, holding the jade box containing the elixir in his hand.

Hurriedly put the jade box into the storage ring, Gu Yan looked at the entrance of the cave with a solemn face, he faintly felt that the black shadow just now was not simple, and his divine sense had not been recovered when he dug up the elixir by himself, and the movements within a radius of several meters were all in his detection.

However, this black shadow seemed to appear out of thin air, appearing directly behind him, if it weren't for the bursting bead blocking it for a moment, Gu Yan might have been seriously injured.

Staring vigilantly at the entrance of the cave, the blood tooth was also held in his hand, the blood tooth itself is an extremely extraordinary imperial soldier, absorbing a lot of blood and evil qi when refining, this demon qi can also be absorbed, feeling the rich demonic qi around it, the blood tooth is extremely excited, and keeps making a "buzzing" sound.

"Boom!"

At this moment, the black shadow suddenly attacked towards Gu Yan, the speed was extremely fast, Gu Yan faintly saw an afterimage, but the black shadow's attack had already reached close range.

With a step on his right foot, avoiding that attack, Gu Yan's figure had just jumped into the air, and the boulder on the ground was directly shattered, but the attack of this black shadow did not stop, and it directly attacked Gu Yan in the air again.

Gu Yan snorted coldly, holding the blood tooth with both hands, and the blood tooth weighing tens of thousands of catties smashed down directly, facing the black shadow.

In the face of the bloody fangs that violently smashed down, the black shadow was not afraid at all, and continued to attack towards Gu Yan.

"Jump!" The black shadow seemed to use its fist to meet the blood tooth directly, and the two collided violently, but the result was that Gu Yan was taken aback, and his whole person was directly shaken away, and he smashed a hill behind him, and the corners of his mouth overflowed with blood.

The blow he had just given him, the masters of the middle stage of the Divine Soul might not dare to catch it hard, but this black shadow not only caught it hard, but also shook itself away, and the strength of this black shadow was much stronger than Gu Yan expected.
