At this moment, Mu Zu spoke again, "Little fellow, your spiritual power has blended both vitality and death qi, and they have reached a balance. Indeed, cultivating where vitality and death qi are mutually balanced is the fastest way to increase your cultivation," and "The Abyss of Corruption is naturally the best choice..."

"However, that Abyss of Corruption has been sealed. Getting out is as hard as ascending to heaven, and getting in is not easy either. Even if you manage to enter, getting out again is even harder. Why does that 'Great Evolution Spirit Venerable' covet my heart? He wants to break through to Spirit God to achieve Grand Venerable. Only then can his main body leave the 'Abyss of Corruption'..."

"Mu Zu, is there truly no way..." Nie Kong's brow furrowed tightly. Without an environment like the 'Abyss of Corruption' that is most suitable for cultivation, wishing to advance from Spirit Control First Grade to Pill Spirit First Grade within two years would be nothing but a pipe dream, let alone achieving the 'Pill Genesis Seven Spirits'."

"There is none..."

Just as Mu Zu sighed, a sudden splashing sound, "Splash..." erupted from Nie Kong's chest, startling Mu Zu. "What is this...?" A moment later, a hint of bewilderment entered Mu Zu's voice, "Little fellow, what do you carry with you?" "It is the 'Abyssal Fire Nether Spring' I just mentioned. It can also be used to condense a Second Incarnation..."

As he spoke, Nie Kong retrieved a small jade vial from his. The material of this vial was 'Absolute Spirit Treasure Jade...', which Nie Kong had requested from Long Xuechan on the day he returned to Lingyu City. Using it to contain the 'Abyssal Fire Nether Spring...' could naturally save a lot of trouble.

Upon opening the stopper, a streak of blood-red light rushed out, drifting onto Nie Kong's shoulder—it was precisely that blood-red liquid resembling a spirit snake. After a moment of, the 'Abyssal Fire Nether Spring...' actually hopped and jumped with excitement, its mood reminiscent of Xiangxiang and Qingyue when they first entered the Tree Heart Space early last year.

"It's a little Water Spirit..."

Mu Zu was surprised, but his voice revealed a deep joy, and he laughed heartily, "Little fellow, you have such a good thing capable of condensing a Second Incarnation, why didn't you bring it out sooner? With it in hand, entering and leaving the 'Abyssal Fire Nether Spring...' will no longer be a problem for you..."

"Really..."

Nie Kong was overjoyed.

Just now, when recounting Hua Mei's situation, he had indeed mentioned the 'Abyssal Fire Nether Spring...', but he hadn't mentioned its ability to condense a Second Incarnation. After all, everyone knew the function of this item, and since Mu Zu hadn't shown any particular reaction at the time, Nie Kong naturally hadn't said much.

Hearing Mu Zu's words now, Nie Kong suddenly realized.

The Spirit Masters outside were indeed familiar with the term 'Abyssal Fire Nether Spring...', but this term had only appeared for a little over a thousand years. Even someone as knowledgeable as Mu Zu could not constantly monitor events outside the Yin Ruins, so it was understandable that he was not aware of the function of the 'Abyssal Fire Nether Spring...' and likely only thought it could suppress the soul.

This small misunderstanding had caused Nie Kong to worry for half a day.

However, fortunately, at the critical moment, the 'Abyssal Fire Nether Spring...' had stirred inside the vial, attracting Mu Zu's attention! Of course, this was also because Mu Zu had not closely inspected Nie Kong's condition before. Otherwise, given Mu Zu's power, even the 'Absolute Spirit Treasure Jade...' could not block his perception.

Mu Zu smiled, "If I remember correctly, I once sensed the aura on this little thing from someone. That person had already achieved Spirit God status three thousand years ago and entered the 'Grand Venerable Spirit Realm'. This Water Spirit must be something that Spirit God left behind on the Tianling Continent..."

The owner of the 'Abyssal Fire Nether Spring...' had indeed achieved Spirit God status long ago!

Nie Kong's heart stirred, but he heard Mu Zu continue, "Although entering the 'Abyss of Corruption' is extremely difficult, it is not without a method. It's just that with your Spirit Control cultivation, it's impossible to even get close to the 'Abyss of Corruption'! If your personal strength has not reached the Heavenly Spirit Realm, even having Yao Tong and the others escort you, you will find it hard to arrive. But with this little thing, entering the 'Abyss of Corruption' will not be an issue..."

"Furthermore, to leave the 'Abyss of Corruption', you must also rely on the 'Second Incarnation' condensed from this spring water! Back then, the Spirit Gods of the 'Grand Venerable Spirit Realm' sealed the 'Abyss of Corruption' precisely to prevent the creatures inside from coming out. Whether human or spirit beast, anyone wishing to leave the 'Abyss of Corruption' must pay with their life, and that includes Spirit Gods like the 'Great Evolution Spirit Venerable'..."

"If you have a 'Second Incarnation', when you leave the 'Abyss of Corruption', the incarnation can pay with its life in your stead, winning the main body a chance to live. Little fellow, if you wish to enter the 'Abyss of Corruption', the first thing you must do is successfully condense the 'Second Incarnation'."

"I understand..."

Nie Kong breathed a sigh of relief, finally able to put his heart at ease.

That the 'Abyssal Fire Nether Spring...' could condense a Second Incarnation did not mean all its water possessed this efficacy. The substance truly capable of condensing a Second Incarnation was something called 'Nether Fire Soul Dew'.

Just like a snake shedding its skin, the 'Abyssal Fire Nether Spring...' would undergo a transformation every fifty years. After each transformation, its actual power would increase, and simultaneously, 'Nether Fire Soul Dew' would be generated. The 'Abyssal Fire Nether Spring...' had absorbed soul power for ten months, and while most of it had completely merged with it, a small portion remained. These residues mixed within the spring water, and over time, subtle changes would occur—this was the 'Nether Fire Soul Dew'.

This liquid separated during the 'Abyssal Fire Nether Spring...'s' transformation and was then randomly sent to a location through the intricate network of underground currents in the Illusory Space. In previous years, the 'Abyssal Fire Nether Spring...' discovered by Spirit Masters when the Illusory Space opened was actually this 'Nether Fire Soul Dew'.

During this current space opening, before the 'Nether Fire Soul Dew' could be found, the 'Seven-Colored Spirit...' that bound the 'Abyssal Fire Nether Spring...' had been taken by Nie Kong. When it was stimulated into a frenzy by the essence of the Spirit Treasure, the 'Nether Fire Soul Dew' was subconsciously reclaimed by it. Although the 'Nether Fire Soul Dew' was separated from the 'Abyssal Fire Nether Spring...', it remained a whole with the spring water. When the spring water leaped out of the pool, it brought the dew along with it.

Nie Kong learned about all these things by continuously attempting to communicate with the 'Abyssal Fire Nether Spring...' on his journey back to Lingyu City, ultimately figuring it out through a mix of guesswork and understanding. Before then, Nie Kong, like other Spirit Masters, was mistaken, believing all 'Abyssal Fire Nether Springs' could be used to condense an incarnation.

In reality, only a small amount of 'Nether Fire Soul Dew' could condense an incarnation, and it was only produced once every fifty years. Now that the 'Abyssal Fire Nether Spring...' had left the Dark Soul Hall, without that environment, even if the 'Abyssal Fire Nether Spring...' transformed again in the future, no 'Nether Fire Soul Dew' would be generated.

Back in the oasis of the Savage Sand Valley, the liquid Nie Kong gave to Hua Mei was the true spring water; the 'Nether Fire Soul Dew' was still inside the 'Abyssal Fire Nether Spring...'. However, getting the 'Abyssal Fire Nether Spring...' to separate the 'Nether Fire Soul Dew' again would require quite some effort from Nie Kong. Although this little thing had become a spirit, its spiritual nature was far inferior to Xiangxiang's. Making it accurately understand his meaning would be rather difficult.

There was no time to lose. With a thought, Nie Kong began snapping his fingers.

"Lo!" However, just as Nie Kong prepared to flick a trace of Spirit Treasure essence, a mass of viscous, dark-green liquid rushed out from Mu Zu's heart and struck the 'Abyssal Fire Nether Spring...'.

"Divine Luo Nectar!"

Nie Kong was stunned. He hadn't expected Mu Zu to use something so precious to nourish this little Water Spirit.

A moment later, with a crisp "swish," the 'Abyssal Fire Nether Spring...' became unusually agitated, instantly enveloping the mass of 'Divine Luo Nectar' tightly. Then, the 'Abyssal Fire Nether Spring...' twisted its body as deftly as a small snake, and strands of blood-red liquid were seen separating from it.

Nether Fire Soul Dew!

Nie Kong was ecstatic. He hadn't expected the little Water Spirit to start separating this substance so quickly. It seemed Mu Zu had also transmitted a thought to it when he offered the 'Divine Luo Nectar...'. Mu Zu was indeed worthy of being an ancient tree that had lived for over ten thousand years, easily making the less spiritually astute 'Abyssal Fire Nether Spring...' understand his intent. If Nie Kong had done it himself, it would have taken at least fifteen minutes to achieve the same result.

With this realization, Nie Kong hurriedly collected the separated liquid into the jade vial. In less than two minutes, the 'Abyssal Fire Nether Spring...' stopped wriggling, and the vial made of 'Absolute Spirit Treasure...' was now filled with 'Nether Fire Soul Dew'—crimson red, like fresh blood.

Mu Zu smiled, "It usually takes a Spirit Master at least a month to condense an incarnation, but if combined with my Semi-Spirit Race mental affinity, it can be successful in ten days at most. Little fellow, are you ready?" Seeing Nie Kong nod, Mu Zu added gently, "Xueyi, Yao Tong, the five of you return to Yin Yue City to wait!"

"Yes..."

The five could only bow and agree.

Now that the location of the 'Abyss of Corruption' was known, the method to enter it was clear, and even the incarnation to ensure a safe exit could be condensed—Nie Kong's plan could no longer suffer any setbacks! Mu Xueyi gave Nie Kong a reluctant look, but finally walked toward the edge of the Tree Heart Space with Mu Yao Tong and the others. A moment later, the five figures merged into the side wall of the space, gradually fading away.

Nie Kong understood his mother's feelings, but there was no way he could abandon this matter. A moment later, Nie Kong took a deep breath, calmed his mind, and poured the 'Nether Fire Soul Dew' into his palm. The 'Yin-Yang Spirit Devourer...' quietly circulated, and the blood-red liquid rapidly permeated his skin, entering Nie Kong's body.

In the blink of an eye, the 'Nether Fire Soul Dew' dispersed throughout his limbs and bones.

"Boom!" A hurricane seemed to rise within Nie Kong's body, and a fierce aura suddenly burst forth. Accompanying this aura was a vast spiritual power. In an instant, Nie Kong's body turned crimson as if on fire, radiating a dazzling, brilliant blood-red glow.

A moment later, wisps of icy coolness emerged from that intense heat. Under Nie Kong's guidance, these wisps of coldness rapidly spread toward his brain... A few seconds later, they touched Nie Kong's soul like countless tiny tentacles. At that instant, the spiritual power generated within Nie Kong due to the 'Nether Fire Soul Dew' seemed to find an outlet, pouring ceaselessly into the depths of Nie Kong's soul...
