There were a total of seven medicinal materials for refining the Soul Gathering Demon Pill, and Ye Mu consumed four medicinal materials before he accurately extracted each part of the medicinal liquid, but this was only the first step.

The next most important and difficult step is to fuse all the medicinal liquids and then condense them into pills, which requires precise soul control and the support of a deep Xuan Qi heritage.

In the Danding, several clusters of medicinal liquids of different colors and shapes began to tumble, slowly approaching each other, Ye Mu couldn't take his eyes off it, and the fine beads of sweat oozing from his forehead also ignored it, he stared at the ball of medicinal liquid in the Ding.

The Xuan Qi in his body surged, constantly converging into the Danding, turning into a green flame to wrap the medicinal liquid, slowly suppressing its volume, and constantly removing the impurities in it, Ye Mu held his breath, deeply afraid that a small mistake of his own would make all this work go to waste.

This starry sky was very quiet, and Fan Yi looked back at Ye Mu, who was concentrating on alchemy, and sighed lightly: "When will Gongzi go back to refining the pill?"

The purple light around the starry sky shone brightly, reflecting the green flame in the danding, suddenly, Ye Mu's heart trembled, the Xuan Qi went out of control, and the green flame rose up, evaporating the medicinal liquid into a wisp of white gas and dissipating.

"Damn! This is about to succeed in condensation, but it has failed!" Ye Mu's face was ugly, and he smashed his fist on the Danding, and he couldn't help but complain in his mouth.

After all, the refining of this Soul Gathering Demon Pill had taken a long time, but it fell short at the moment before it was about to succeed, so how could Ye Mu not be angry?

Ye Mu looked up at the depths of the starry sky, the reason why he was unstable just now was because there was a powerful gaze staring at him, which made him unconsciously make a mistake and did not control the temperature of the flame.

Ye Mu's body mobilized the Xuan Qi, and he shook towards the depths of the starry sky: "Who is Your Excellency? Why are you hiding in the dark and snooping? Don't you dare to show your true face and see people?"

Fan Yi flashed to Ye Mu's side and asked in a low voice, "Childe, what's wrong?

Ye Mu replied in a low voice: "I just feel it, and I don't know if someone is really there, maybe it's my illusion." ”

In the depths of the starry sky, in a dark space, a figure shrouded in a black shirt slowly stood up, his eyes like stars and the sun and moon flickered, and a step was like teleporting thousands of miles.

In just a few breaths, Ye Mu saw a black shadow appear above the starry sky out of thin air, and couldn't help but squint, but found that the person who came was like a fog, and he couldn't spy on its depth at all.

"Your senses are very keen, you almost succeeded, but it's a pity!" said the man in a voice that was clear but could not be heard male or female.

Ye Mu knew very well that the other party must be a super strong person, and said loudly at the moment: "I don't know if Your Excellency is passing by here, or if you live here?" If I have a place to disturb you, please Haihan, and I will leave." ”

"Oh, you don't pursue it, just now you failed to condense the pill, a large part of it is because of me, don't you want to ask me for compensation?"

In the starry sky, the black-shirted figure asked slowly with a hint of a smile, as if Ye Mu's words surprised him a little.

Ye Mu shook his head slightly and said, "My alchemy failed, purely because my skills are not perfect, and I can't blame others." When the black-shirted figure heard this, the corners of his mouth slightly hooked a curvature, and the figure flashed to two meters in front of Ye Mu, and said with a smile: "I said it has something to do with me, it has something to do with me, so let's take you to a place, there is something there that may be useful for your cultivation, but whether you can get it or not depends on yourself, how about it?"

Hearing this, Ye Mu was silent, thinking quickly in his heart, after all, this person had never seen him, he didn't know if he was friend or foe, he dared to go with him, if he encountered danger, he might die, but from the black-shirted figure, Ye Mu did not perceive any hostile aura.

After thinking about it again, Ye Mu still decided to go with the black-shirted figure, because the reason was very simple, if he had any thoughts about himself, he could do it here with his strength, and there was no need to tell a lie.

Secondly, no matter how much Ye Mu mobilized his strength, he couldn't see through the face under the black shirt, and even his physical form was blurred, and this strength was probably several realms beyond himself.

Therefore, Ye Mu was no longer worried about the danger of his life, and decided to go with the black-shirted figure, who tapped his toes, and his body fluttered gently like a feather, as if there was no trace of restraint around his body, and this starry sky was for him to roam.

Ye Mu followed closely behind, finding that he had to mobilize all his strength to barely keep up with the speed of the black-shirted figure, which shocked him again.

You must know that Ye Mu's speed may not be comparable even to a powerhouse in the late stage of the Xuan Realm, but the man in black in front of him looked calm and composed, obviously not doing his best, which made Ye Mu understand that he might have met a big person.

After about ten minutes of flying, the black-shirted figure slowly stopped and landed on a floating island, which was different from the starry sky that Ye Mu had seen before, the starry sky here was purple, and there was a layer of enchantment above the floating island.

Even Ye Mu, who had the cultivation of the peak realm in the early stage of the Xuan Realm, had spent some strength to break through the enchantment and enter the floating island, and after landing, Ye Mu asked respectfully: "My name is Ye Mu, and I haven't consulted the senior name yet!"

The black-shirted figure walked slowly towards the center of the floating island, and replied casually: "It doesn't matter what the name is, you can just call it "Yi"!"

"Senior Yi!" Ye Mu nodded, his attitude was respectful, after all, people could slaughter their own strong people with their fingers, so they should naturally be humble in all aspects.

The black-shirted figure did not refute Ye Mu's name, but kept walking towards the center of the floating island, Ye Mu followed, raised his eyes and looked around, and found that the aura here was a little different, and the Xuan Qi here was more abundant.

After walking for about three minutes, passing through the rows of towering stone pillars, Ye Mu saw a huge square with a severely cracked square, and the surrounding floors had been shattered, and it looked like it had been abandoned for many years.

Yi walked to the edge of the square, pointed to the only stone wall on the steps of the square that seemed to be relatively intact, and said slowly: "It is said that there is something hidden in that stone wall, and only the Xuanshi who can resonate with the stone wall can get what is in it, otherwise, even if the stone wall is destroyed, you will not be able to get half of it." ”

Ye Mu squinted at the stone wall, roughly estimated, it was two meters wide and three meters high, and there were some patterns carved on it, including a green-shirted swordsman with a sword to slash the snake demon, and a strong man holding a water and fire stick to beat the wolf demon......

"Senior Yi, what do you mean, let me give it a try?" Ye Mu turned his head to look at Yi and asked.

Yi nodded and said, "That's right, but before you get to the stone wall, you need to pass through this square, there are some traps in it, you have to be careful." ”

Hearing this, Ye Mu released his soul power to scan the square, and sure enough, he found that there was a cold aura under the floor of the square, and immediately pulled out the Heavenly Sword, and the cyan sword light shrouded his body, and he rushed out.

The moment Ye Mu stepped into the square, a heavy roar sounded, the floor caved down, and one after another broken blades that made the hairs stand up flew out, shooting towards Ye Mu with a sharp sound.

"Jingle Bell!"

The Heavenly Sword kept swinging, the sword light flashed, and Ye Mu was like an impermeable wall, blocking the flying broken blades one by one three feet away from his body.

At the edge of the square, Yi observed Ye Mu with his eyes, and said secretly in his heart: "Sure enough, it is the Jade Sword Heart Sutra, but it seems to have been improved, this kid must be the successor of that guy, I didn't expect that you would secretly cultivate juniors, it really annoys me!"

In the square, Ye Mu relied on his solid defense and strong strength to fall unscathed in front of the stone wall, which was partly because some of the mechanisms in this square had gradually failed with the passage of time.

Ye Mu put the sword into the sheath and carefully looked at the stone wall in front of him, at this time, a voice came from his ears: "Feel the stone wall carefully, and experience it with your heart, when your soul power is connected to the stone wall, the Xuan Qi will act as a medium, and the two will resonate." ”

With Yi's reminder, Ye Mu closed his eyes, his soul power gushed out, and he carefully felt the stone wall, in his sea of consciousness, he could only feel a cold wall without any breath, which made Ye Mu frown slightly.

Because Yi said that not everyone can resonate with the stone wall, Ye Mu already thought that he was not such a person at this time, but just when he was about to give up, a faint brilliance suddenly appeared in his mind.

"What is this?"

Ye Mu was full of doubts, and the soul power that he wanted to withdraw poured out again without reservation, and the Xuan Qi involuntarily released out, enveloping the entire stone wall.

Judging from the outside world, Yi muttered: "Sure enough, it resonated, no wonder even the green candle was handed over to him!"

The little light in Ye Mu's mind slowly outlined the outline of a book, and then a shiny book appeared, and then a slight clicking sound sounded, and Ye Mu opened his eyes.

There was an extra book with a purple cover in his hand, without a title, Ye Mu looked up at the stone wall, and found that the stone wall was the same as before, he turned to look at Yi, raised the book in his hand, and said loudly: "Senior Yi, is the thing you said this book?"

Yi said softly, "Come back, you have been approved by the stone wall!"

Ye Mu flew back to the edge of the square, this time he was not attacked by the organs, he handed the book to Yi and asked, "Senior, this book has no title, and I don't know the words in it, what is this recorded?"

Yi stretched out his right hand to take the book handed by Ye Mu, and the latter found that it was a hand as white as jade with slender fingers, more like a woman's hand.

Turning the first page of the book, Yi said slowly: "This is not an ancient book, nor is it a technique or a mystical technique, this is a piano score!"
