After sleeping for six or seven hours, Qin Lingyun's fatigue had all disappeared, after all, a cultivator's physique was much stronger than that of ordinary people.

  Sitting on the stone bench in the courtyard, Qin Lingyun picked up the clear tea on the stone table and took a light sip. A refreshing fragrance filled her mouth and teeth, making her feel extremely comfortable all over.

  "This place is indeed very considerate, with just a slight instruction, someone will bring tea over, convenient and quick." Qin Lingyun's eyes sparkled with a hint of smile.

  Xingdi, who was floating above the stone bench, interrupted Qin Lingyun's self-reflection without hesitation: "Don't you hurry up and swallow the Yu Huan Dan? The longer you drag it out, the weaker the medicinal effect of the Yu Huan Dan will be."

  Qin Lingyun glanced at Xing Di and said, "In just a short while, how much medicinal effect can be lost?" Although she said so, she still stood up and walked towards the building in front of her.

  Yuè Huan Dan is a miraculous elixir, different from ordinary elixirs. Once successfully refined, it's best to consume it as soon as possible. If time drags on, the efficacy will gradually weaken. However, Qin Lingyun's successfully refined Yuè Huan Dan won't lose its efficacy completely in just ten or eight years.

  It's still better to take it earlier.

  Inside the building, pushing the door in is a small hall, with a spiral red wooden staircase leading to the second floor. The alchemy furnace is on the left side, and there is a bedroom on the right side.

  Qin Lingyun decided to go into closed cultivation in the alchemy room and swallow the Jade Return Pill, as it was more spacious here.

  Sitting cross-legged on a futon, Qin Lingyun flipped her palm over, and a small jade bottle appeared in the center of her hand. She pulled out the stopper and poured out a pellet of medicine that looked like a jade stone from the small jade bottle. A strange sweet fragrance wafted out.

  Before taking the Jade Return Pill, first gather your spiritual energy and compress all of the cold ice spiritual energy in your body into your dantian. The words of Xing Di slowly flashed through Qin Lingyu's mind.

  Because this time is to activate the second spiritual root, the spiritual power of the first spiritual root must be retracted, so as not to interfere with the manifestation of the second spiritual root. This is very important, if the spiritual power is not retracted, when the second spiritual root has not yet stabilized, the cold ice spiritual power will erase the properties of the second spiritual root again, and all previous efforts will be in vain.

  Qin Lingyun's eyes slowly closed, and under the control of her divine consciousness, all the spiritual energy in her body flowed bit by bit towards the position of the elixir field. The spiritual energy that originally filled the meridians all began to flow, like cloud-like spiritual energy concentrated at the elixir field, making a strong compression.

  The spiritual energy formed a cluster of icy blue gas in the continuous compression, and the mist inside became more and more dense, but it never condensed into liquid unless it was a cultivator in the foundation-building period. Otherwise, the spiritual energy could not be transformed into a liquid state. Once the spiritual energy was transformed into a true liquid state, the quality of the spiritual energy would undergo an essential change, at which point it was called True Yuan Force.

  After a short while, Qin Lingyun's spiritual energy had all been withdrawn to the dantian position. She introspected with her divine sense, checking several times, and confirmed that there was indeed no spiritual energy existing outside the meridians. Without hesitation, she threw the Jade Return Dan in her hand into her mouth.

  The Jade Dan was as hard as jade, but once ingested, it quickly dissolved into a liquid that flowed into the body, forming a special energy that slowly circulated inside.

  Every time it runs through a place, it spits out a ray of light, and then continues to move forward below.

  According to Xingdi, the energy transformed by Yuhuandan will spontaneously search for the hidden spiritual root in the body. Once found, it will tightly wrap around the spiritual root and slowly peel off the outer shell that relies on the hidden spiritual root.

  This shell is a relative concept, and in fact it is also a strange energy fluctuation. However, except for the energy transformed by Yuhuan Dan, there are few other things that can detect such a strange energy fluctuation.

  Qin Lingyun's entire spirit had fallen into a state of neither sorrow nor joy, neither worry nor pleasure. As her entire spirit sank into an empty and ethereal state, the faint virtual shadow in the sea of consciousness suddenly and slowly burst forth with a faint radiance.

  This illusory shadow is a seated figure, vague and unstable, which is the Dao heart evolved by Qin Lingyun, also representing the direction of the great Dao law that will be achieved in the future.

  The Tao heart is still just a small seed, with a thread of the law's sprout inside. However, to think about breaking through the foundation period, without this seemingly weak Tao heart, it is absolutely impossible to succeed.

  Every cultivator who breaks through the foundation period will form a Dao heart sprout. Only when the Dao heart and cultivation are matched, can one avoid being disturbed by demonic thoughts; otherwise, once demonic thoughts arise, all cultivation will be reduced to nothing.

  Qin Lingyun's Dao heart suddenly stirred at this moment, and the energy transformed by Yuhuandan also stayed in the position of Xuanzhong Hole, with a burst of colorful light.

  In Qin Lingyun's body, the aurora intertwined and twisted into a spiral-shaped strip, while the energy transformed by Yuhuan Dan was disappearing bit by bit, as if being swallowed up by something.

  In the alchemy room, Xing Di stood with his hands behind his back, his face solemn as he stared at Qin Lingyun. From the moment Qin Lingyun had gone into seclusion and swallowed the Jade Return Pill, three days had passed. Yet, Qin Lingyun remained motionless in her cross-legged sitting position, without even shifting her body half a step. According to experience, generally after swallowing the Jade Return Pill, one would wake up within two or three hours at most. But Qin Lingyun's situation seemed somewhat strange.

  "I hope nothing goes wrong." Xingdi thought to himself. In fact, there was another situation that could lead to an increase in the time it took to open her spiritual root, and that was if her hidden spiritual root wasn't a normal five-element spiritual root, but this possibility was somewhat remote.

  After all, Qin Lingyun already has a spiritual root that is a variant of the ice spiritual root, and another spiritual root attribute is at least 99% likely to be an ordinary five elements.

  In his heart of hearts, Xingdi naturally hoped that Qin Lingyun's spiritual root would be stronger, but at this moment he couldn't help with anything and could only wait aside.

  The spiral-shaped strip in Qin Lingyun's body became clearer and clearer, until the dawn broke, when all the light suddenly shattered, a pure black long silk slowly emerged like a winding snake.

  A pure black long silk suddenly appeared, and the virtual shadow in the sea of consciousness fluctuated, gradually becoming clear. It was vaguely visible that it was a human shadow, with a black air under the cross-legged position, constantly churning, slowly solidifying into a black lotus flower.

  Inside the alchemy room, the entire space suddenly began to darken strangely. In the dim environment, a black light ring slowly appeared behind Qin Lingyun's head, although it was vague, but it really did appear.

  Then, the entire room seemed to disappear, and what appeared in front of Xingdi's eyes was a vast expanse of emerald green ocean. Endless cold air churned within the ocean, and on its surface, large patches of black lotus grew rapidly, almost covering the entire ocean.

  Astonishment flashed across Xingdi's eyes, and this time he was thoroughly shocked.

  "It's actually a rare and precious Dark Spirit Root." Xing Emperor muttered to himself.

  At this moment, Qin Lingyun suddenly woke up. She opened her eyes and all the strange visions disappeared immediately, as if she had opened her eyes to daylight replacing night.

  Qin Lingyun found that Xingdi's gaze towards her was so strange, and earlier she was in a daze, not knowing what had happened, so a hint of surprise flashed through her mind.

  "What happened?" Qin Lingyun couldn't help but ask.

  Xingdi slowly regained his composure from the shock, and he recounted the scene to Qin Lingyun. Then, with a serious expression, he said: "From now on, don't easily display your aura, or you will attract trouble."

  Qin Lingyun was surprised and couldn't help but wonder: "What kind of trouble could it be?"

  "There are four top-notch spiritual roots in this world, namely light spiritual root, dark spiritual root, mixed yuan spiritual root, and empty spiritual root. Your spiritual root is the dark spiritual root. The strange phenomenon that appeared behind you just now is called 'Bihai Sheng Heilian', which is an aura that only ancient great demon gods can possess. In other words, you have the potential to become a top-notch great demon god, but you are too weak and small. If exposed, you will definitely be jointly killed by others."

  Qin Lingyun had heard of the four top-notch spiritual roots and the Great Demon God for the first time, she didn't understand what the Great Demon God was, but she understood the principle that a tree standing out in the forest will be felled by the wind, without enough strength to match, one cannot lightly expose their secrets.

  "What is Dà Mó Shén?" Qin Lingyun asked again, she had to figure out these things, otherwise she couldn't determine the direction of her future cultivation.

  Xing Di said slowly: "The Great Demon God is just a title, as long as the cultivation of the demonic path can break through the Void Immortal and ascend to become a true immortal, it will be called the Great Demon God. However, I also only occasionally saw this in ancient books, whether or not it's true, I don't know. But you have such an extraordinary phenomenon, as long as you are careful and cautious and do not fall, your future achievements will be boundless."

  Qin Lingyun, however, was not as optimistic as Xingdi. She had a clear understanding of herself and knew that the realms of True Immortal, Void Immortal, and Great Demon God were still too far away from her, like a pavilion in a dream, completely illusory and fleeting. What was most important and practical for her was to focus on cultivating diligently and entering the Foundation Establishment stage as soon as possible.

  As a cultivator, one cannot be too ambitious and should take solid steps to eliminate unrealistic fantasies from their mind. Qin Lingyun asked: "Since my second spiritual root is the Dark Spiritual Root, what kind of technique should I cultivate?"

  The Emperor of the Stars revealed a hint of bitter smile: "I didn't expect you to have this kind of spiritual root, so I couldn't provide you with any cultivation techniques, not even the basic ones for the Qi Refining stage."

  Qin Ling's mouth opened slightly, almost unable to close it. What's going on? It seems that the spiritual root is too strange and can't find a suitable cultivation method. Isn't this kind of dark spiritual root useless?

  It's said that chicken ribs are tasteless when eaten, but a pity to discard. Qin Lingyun felt an emotional turmoil of laughter and tears, she didn't know what to say anymore, just now her heart was still secretly delighted, after all, the Dark Spirit Root is one of the four top-notch spirit roots in legend, and she had been looking forward to it.
