Yun Cang looked at the old man with a shocked expression, and the old man unmistakably said the strength of the Yellow Tree Demon.

"Hehe, there's no need to be so shocked, I just saw through this leaf, except for the leaves of the Yellow Tree Demon, which has the ability to change space, other soul beasts don't have such ability. The old man said casually.

Although the old man covered it up, he couldn't stop Yuncang's suspicions, the old man was unfathomable, and it was definitely not that simple.

"May I ask the senior name!" Yun Cang was curious for a moment, and then said.

"Daimyo, just call me Kong Fu. The old man thought for a while and told Yuncang his name directly.

"Senior Kong Fu! It's really a good eyesight, the kid went to hunt the Yellow Tree Demon a few days ago, and he had a lot of twists and turns. Yun Cang didn't hesitate at all, he said it all, in front of Kong Fu, compared to Yun Cang, he couldn't hide anything if he wanted to.

The old man named Kong Fu in front of him, when Yun Cang faced him, it was like a void in front of him, looming, and Yun Cang guessed that the old man must be a powerful controller or beast soul knight.

"Hehe, what's so good or bad in your eyes is written on you. The old man smiled, as if he had guessed as a matter of course.

"Hey, by the way, kid, you need to cultivate more of your Spiritual Qi source power, this thing is very useful. Kong Fu seemed to suddenly remember something, and spoke.

Yun Cang nodded: "Well, I know the seniors, but the kid has something to understand and wants to ask the seniors." ”

If Kong Fu is really strong, then his knowledge must not be ordinary.

"What is the source power of the underworld?" Yun Cang said in a low voice, this source of the underworld qi Yun Cang himself couldn't tell what it was, and when the Huang Tu Tree Demon saw Yun Cang's source power of the underworld qi before, he was also startled, and then kept repeating these words.

Kong Fu saw Yuncang asking, and with one move, a transparent film of light enveloped the two of them.

"See, this is the source power of the Underworld. The old man blocked out the outside sound and said to the light film.

"Where should we start with this? The source power of the Spiritual Qi was originally the power of the Meditation Realm, and in the distant past, when the ancient master advanced to the Meditation Realm, he naturally mastered the source power of the Spiritual Qi. This kind of power is more refined, and it is very effective for cultivation and penetrating the exercises. The old man paused, as if with a wry smile on his face.

"I don't know if it's the regression of the times or the fall of talents, one day in the future, the master of the meditation realm suddenly lost his sense of the source power of the meditation realm, just like the oxygen that disappeared in the air, nowhere to be found, day after day, year after year, the word source power of the spirit has been forgotten by many people, even including the controller of the meditation realm. ”

"Now only a very small number of people with better talent will comprehend the source power of the Immortal Qi, it is really not as good as the generation, haha. ”

The old man wiped his lower palm, grabbed it with one hand, and a stream of transparent energy appeared in his hand, with a faint fluctuation.

"So that's the case?" Yun Cang also understood a lot after the old man's explanation, and there was still such a period in the history of the original controller.

Yun Cang stretched out his finger at the same time, and a trace of the source power of the dark qi appeared, which was a little weaker than the old man.

"Well, the controller with the source power of the underworld qi is like having wings, flying freely in the sky and on the ground, just like the controller and the beast soul knight. The old man looked at the source power of the dark qi on Yun Cang's fingers, and there was a hint of relief on his face.

Yun Cang nodded silently, not proud of the fact that he had the source power of the Dark Qi, but because he had the source power of the Dark Qi, he had to take it seriously.

I had heard it in Kong Fu's mouth just now, and it seemed that this Spiritual Qi source power was no longer an energy unique to the Meditation Realm, but now it was an even rarer energy. It seems that if the master of any stage comprehends the source power of the underworld, his strength will increase.

Yun Cang was still immersed in Kong Fu's words, and he didn't wake up until Yun Yi shook Yun Cang's shoulder.

"You were absent-minded just now, what's wrong?" Yun Yi asked with his head turned his head sideways.

"No, because I met an old man named Kong Fu....... Yun Cang told Yun Yi everything about Kong Fu.

After a while, the two of them were always walking in the dark market, and Yun Yi said thoughtfully: "This old man Kong Fu, maybe he is the strong man of which force!"

Yun Cang speculated a little according to what Yun Yi said, but he didn't know. What is the origin of this Kong Fu, it is estimated that he can only say it himself, this vast area is almost unimaginable to Yuncang.

followed Yun Yi to walk around the dark market for a while, but still didn't see a suitable one, so he picked a fruit whose name he didn't know and returned to the Yun family.

Yun Cang has the war ape palm that Kong Funa bought before, and the soul of the underworld, and there is no need for anything else for the time being.

As soon as he returned to the Yun family, Yun Cang went into the house, and Yun Cang couldn't wait for these two exercises.

Yun Yi only looked at Yun Cang's back, so he could only shake his head helplessly, and took the fruit to the cultivation ground.

Back in the room, Yun Cang didn't rush to look at the War Ape Palm Exercise Bead, but sat on the edge of the table and took out the Soul Empowerment Book.

Looking at this somewhat yellowed book, even the corners of the pages are a little broken, it seems to be an old thing.

Still thinking about what Kong Fu said in his mind, he didn't know what else had happened to the controller in this long history, and Yun Cang suddenly became interested in history.

"Let's take a look at the book for now. Yun Cang stretched out his hand to open the book, and this action seemed to be a little rusty.

On this continent, there are very few books, and they are basically recorded into the beads by people through the power of the source, and there are fewer and fewer books, and few people read them.

Where the pages of the book come into view, the fonts seem to come alive in front of Yuncang's eyes.

"It doesn't seem to have been written in ordinary ink. Yun Cang looked closely, and these words seemed to contain some energy.

"Stygian Qi Source Force?!" Yun Cang reacted, the font of this book was actually engraved with the Stygian Qi Source Force.

"The source power of the underworld, a product of ancient history, was discovered and carried forward by the rulers ......of the southern countries. "The origin of the source power of the underworld qi was first introduced at the front of the book, and Yun Cang read it word by word, and the content of the book was quite attractive.

The book is not too thick, and it can be regarded as an average thickness.

As soon as the content of the book changed, he suddenly talked about an ancient technique of using soul beast bone transplantation to strengthen the body, which made Yun Cang praise the wisdom of the historical people, this kind of secret technique is really exquisite, and Yun Cang found that the ancients did not regard the source power of the underworld as a force, but as a way of survival, and the power of the origin and the source of the underworld are everywhere, and can be used everywhere in life, even higher technology.

"This, it's just amazing!" Yun Cang straightened up slightly, adjusted his sitting posture, and exclaimed.

Putting the book aside, the other hand had already taken out the exercise bead of the war ape's palm from his arms, and the beads were glowing with fiery red, and through the beads, he seemed to be able to feel the brutal power of the beast soul in it.

This is a practice for the later stages of the meditation realm.

Flattened the exercise beads, and the mind penetrated into it with the origin of thunder, it was still the mysterious figure, this time it was different from the exercises that Yun Cang saw, this was the exercises of the beast soul knight.

In the mysterious person's body, the beast soul burned, and it seemed that it was also an ape beast soul, awakening the energy in the body, and the beast soul phantom appeared behind him, and dozens of feet tall apes appeared in the exercise beads, which was larger than the dead wood ape king.

As soon as the ape appeared, the hurricane swept by, and the earth trembled with the ape's breath, and I could clearly see that the beast soul energy was converging towards the arm of the mysterious man!

Luck for a few seconds, until the arm trembled slightly, as if it could not bear the powerful energy of the ape, and slapped it with one palm!

It was no less powerful than the Shattering Thunder Hammer, and with the palm of his hand slapping out, the ape behind him sat with the same movement, and the void in front of him twisted, bursting out with powerful energy fluctuations!

"Is this the War Ape Palm, the power is not small!" Yun Cang withdrew from the exercise bead, it seems that this War Ape Palm is a higher level than the Destruction Thunder Hammer, if the complete Destruction Thunder Hammer is a fifth-order exercise in the Meditation Realm, then this War Ape Palm should be a seventh-order exercise in the Meditation Realm!

With Yun Cang's current strength, it can be seen that this War Ape Palm Exercise is quite rare, how can the Meditation Realm Seventh-Order Exercise be sold so cheaply?

Yun Cang once wondered if Kong Fu gave him a discount, and when he met Kong Fu, this was the old man's attitude towards Yun Cang was unusually good, and he even gave him the book of Soul Endowment.

"Let's go and thank that Kong Fu senior another day!" Yun Cang thought in his heart.

Yun Cang held the War Ape Palm Technique in front of him, and remembered Kong Fu's words, it is not impossible to practice this exercise, it requires an ape-like soul beast arm bone, and now Yun Cang has exactly one arm of the Dead Wood Ape King on his body, and the rest of the answers should all be in this Soul Qi Endowment.

Yun Cang spent nearly half a day reading all the books, although it was a bit rough, but the general content was already understood.

The rest of the answer, of course, was also found in the book, Yun Cang was now sitting at the table in a daze, this answer was somewhat unexpected, and the book was on that page.

"Through the source power of the Underworld, you can transplant the bones of the soul beast and replace the previous arm!" Yun Cang originally thought that this was an ancient technique, but he didn't expect to use it on himself so soon.

He looked at the exercise beads, rolled up his sleeves and looked at his left arm, feeling a little chill in his heart.

"Do you want me to take out my own arm, and then put the Dead Wood Ape King's arm inside?" Yun Cang's face was a little ugly, and he took out the Dead Wood Ape King's arm from the storage formation.

This bone was a point longer than Yun Cang's entire arm.

"This, this size is not the same!" Yun Cang was a little worried, and threw the arm on the table casually.

At this time, the origin of thunder incarnated as a girl, sitting on the origin core, with a confused face, she had experienced many years of cultivation, although she had also heard of the fame of the underworld qi transplantation, but she didn't expect that now that the source power of the underworld qi had disappeared for many years, this technique had regained sight, but this was somewhat difficult, right.......
