"This kind of memory crystal can only be refined by a few of the peaks of the Golden Immortals and even the Daluo Golden Immortals after they understand the method of refining. However, I think the method of refining should have been lost now..." The Demon Lord of the World-Destroying World-Secret Stared at the shiny dust in the flame with curiosity. He had only seen this kind of thing in ancient books, but he had never really seen it.

"If you want to refine some elixirs on your soul in the future and add this memory crystal, your success rate will be much higher. After the refining is successful, your quality will be more pure than other elixirs..."

Hearing this, a look of surprise appeared on Liu Chu's face. It was the first time he had heard of this so-called memory crystal that he had to add to refining innate advanced pills.

"Haha, the secret of this thing has been cracked. I have completed the task so that you may not have nagged in my ears and caused you to lose your prescription... But there may be only some useless memories in yours..."

Seeing Liu Chu's expression, the Demon Lord of Destroying the World smiled, then stood up and said, "It's getting late, so you should rest early. Tomorrow is the time to save people, don't delay. That guy, Demon Tiger, put all his expectations on you."

After saying that, he turned around and went to the outsider. Diana hesitated for a moment, and then gave Liu Chu a message before slowly withdrawing.

Looking at the two people leaving the room, Liu Chu smiled and turned his eyes to the five purple dust in the flames in front of him. After pondering for a moment, he finally waved his hand in a little bit, and a memory crystal fell out of it, and then slowly floated in front of Liu Chu.

With his eyes fixed on the memory crystal, Liu Chu slowly closed his eyes, and while his eyes were closed, a suction force suddenly emerged. Under this suction force, the purple shining dust suddenly turned into a tiny stream of light, shot straight into Liu Chu's forehead, and then disappeared...

When this memory crystal merged into his forehead, Liu Chu's body trembled violently, and his face suddenly tense, and a faint pain came from his head.

Liu Chu frowned and endured the faint pain. In his feelings, the memory crystal hit his soul like a bullet, and then penetrated into it...

Fortunately, the pain did not last long and gradually disappeared...

Feeling the gradually dissipating pain, Liu Chu breathed a sigh of relief. However, as soon as he let go, he suddenly noticed that a strange fluctuation suddenly appeared between the surrounding world. Strands of extremely faint strange airflow penetrated out of the fluctuations in the space, and finally slowly invaded from his forehead...

With this strange airflow entering the body, Liu Chu immediately realized ecstatically that the soul strength contained in the soul was actually beginning to increase at an extremely slow rate!

"It's actually the origin of the soul?"

Liu Chu almost tried every means to achieve the origin of the soul in the soul, but he still could not improve them at all. But now under the influence of this memory crystal, the free soul origin that could not be absorbed by ordinary methods was actually pulled out and then integrated into his soul...

Liu Chu felt the origin of the free soul gradually strengthening in his soul. After a long time, he gradually calmed down. As he calmed down, a purple light particle emitting light appeared in his mind. A strange suction force emanating from the light particle. This suction force was not strong, but it seemed like there was a strange power, pulling the origin of the free soul that countless powerful people were helpless from the heaven and earth...

The free soul origin, like a chaotic aura, slowly penetrated out of the space, and then continued to penetrate into Liu Chu's eyebrows.

This absorption of the origin of the free soul lasted for nearly three hours, and the light and suction emitted by the purple light particles gradually weakened. Obviously, this memory crystal cannot last for too long...

As the light emitted by the light particles became dimmer and dimmer, a long time later, a slight crackling sound suddenly sounded in Liu Chu's mind.

As the memory crystal ruptures, the strange suction force stops. The free soul source around him disappears suddenly, and it is useless to let Liu Chu retain it... At the same time, some broken memory fragments also pour into Liu Chu's mind, and Liu Chu felt that this scene made people feel inexplicably familiar, but these memory fragments are a piece of a person's combat and cultivation and how to sense the soul's origin!

The boy in my memory seemed to be saying something...

Feeling this scene, Liu Chu couldn't help but smile bitterly. However, just when he was helpless, the memory crystal that was about to disappear in his mind suddenly burst out with a strong light. Under this light, even Liu Chu's soul felt a sensation of pain.

The severe pain gradually faded, and just as Liu Chu was a little panicked, a very vague and crisp whisper came from the bursting of light...

"The souls returned, but the resentment remained unabated. I wandered for seven days, and my wisdom dissipated..."

The vague sound echoed in Liu Chu's mind, like the sound of Sanskrit, making people feel a sense of trance.

The trance did not make Liu Chu lose his mind. Although the chanting sound in his mind was vague, he also recorded as much as possible. After recalling the chanting sound three times, it completely disappeared...

In the room, Liu Chu slowly opened his closed eyes, and there was a look of contemplation on his face.

"It is said that some strong people can leave soul marks on some objects. If I expected it, the previous voice should have been left by ancient strong people, but the years I have experienced are too long, which has become much blurred..." Liu Chu murmured in a low voice.

Liu Chu frowned and murmured in a low voice. After a moment, he thought: "It seems to be a mantra, but it is obviously incomplete. I don't know what it does..."

After pondering for a while, it was still fruitless. Liu Chu had to shake his head helplessly and put the remaining four memory crystals into the ring. The effect of this thing to absorb the origin of the soul is too important for Liu Chu, but unfortunately the duration is too short and it cannot be squandered at all, so it cannot be used easily. After all, maybe when refining elixirs in the future, this thing will also need to be raised...

Sitting cross-legged on the bed, Liu Chu sighed lightly, then closed his eyes slowly again, and his lips were also slightly squirming while closing his eyes. If you listen carefully, you will find that it was the previous mantra obtained from the broken memory crystal...

A low and vague sound slowly sounded in the room. After nearly half an hour, the peaceful world in the room suddenly had a strange fluctuation!

Swish!

At the moment when the slightest fluctuation in the room was rising, Liu Chu's closed eyes suddenly opened, and his face was filled with shock. He found that at that moment, he actually felt the existence of the free soul source between heaven and earth!

Liu Chu frowned, and after a moment, he suddenly grabbed his palm, and a dazzling sperm burst out from his dark eyes.

"Is it the reason for that mantra?!"

In the room, Liu Chu looked at the space that was fluctuating in the room before. There was an unconcealable look of shock and surprise on his face. At the moment he entered the state of cultivation, he clearly felt the existence of the free soul origin in the world!

The origin of the free soul is an extremely mysterious energy. It does not have the power of spiritual energy, but it is a great nourishing thing for the soul. However, the origin of the free soul is like chaos and is extremely difficult to sense. In ancient times, those alchemists were able to sense the existence of the origin of the free soul and absorb it because of some special soul skills. However, in today's era, the so-called mysterious soul skills have long disappeared, and few alchemists know how to sense the origin of the free soul and absorb it...

The surprise on his face gradually subsided. Liu Chu suppressed the volatile state of mind in his heart, and then slowly calmed down again. His mouth was constantly muttering a mantra obtained from the memory crystal.

Liu Chu closed his eyes for about half an hour, and the calm space in the room finally showed another slight fluctuation...

Liu Chu was not shocked again during this fluctuation. In his perception, in this empty world, which was originally filled with the energy of heaven and earth, strands of extremely small, chaotic airflow suddenly appeared. These airflows were hidden very deeply and were covered by the rich energy of heaven and earth. If it weren't for the mantra, Liu Chu would definitely not have been able to find it out.

"Are these the origin of the free soul..."

Liu Chu's mind was staring at these extremely faint airflows. After a moment, he realized that the origin of this free soul was extremely faint and extremely fragile. Even if it was occasionally sucked into the body, it would be crushed by the energy of the world around him. No wonder few people could sense the existence of the origin of the free soul.

Liu Chu was also quite happy when he sensed the existence of the free soul's origin in a normal state of cultivation for the first time. As long as these free soul sources are successfully absorbed, the free soul's origin will gradually fill the soul, sooner or later, his soul will gradually increase. At that time, his alchemy level will definitely reach the innate level!

As long as Liu Chu can successfully reach the level of a congenital high-level alchemist, even other super strong people at the Golden Immortal level will be more polite to him. With this identity, Liu Chu knew in his heart that even if he went to Xun'er's ancient clan, the treatment would definitely not be low.

After all, even if you look at this world, you are quite rare. For a high-level innate alchemist, some other powerful people at the Golden Immortal level will definitely come to be thugs for you. This is beyond doubt!

The treatment and benefits of becoming an innate high-level alchemist flashed through his heart. Liu Chu also felt a little hot in his heart. He immediately calmed down, and then... he was suddenly stunned...

The reason why he was stunned was because Liu Chu suddenly discovered that he seemed to have no method to absorb the origin of the soul!
