Chapter 429: Powerhouse from a Higher-Level Interface

The "Master" swept a light glance at the Demon Emperor, and seeing that he no longer possessed his former arrogance, could not help but let out a series of soft chuckles from within his black robes!

"The last Demon Emperor of over ten thousand years ago, in order to comprehend the 'Yin and Yang Qi', actually gave up a golden opportunity to ascend to the Demon Realm! Thinking back on it now, do you feel any regret?"

At the mention of the 'Yin and Yang Qi', the Demon Emperor naturally associated it with that great book from the Underworld. It was from that book years ago that he had obtained a wisp of 'Yin and Yang Qi', and from then on, he had embarked on a path of no return! Even until his lifespan was exhausted, he had never comprehended the mysteries within it!

Seeing that the Demon Emperor did not speak, the Master continued:

"Demon Emperor! I could guess a fraction of your original intentions; you wanted to break the laws of heaven and earth to achieve immortal cultivation in the Human Realm! But you forgot one thing! If the 'Yin and Yang Qi' were so easy to comprehend, cultivators of the Human Realm would not need to ascend to the Demon Realm to seek a higher state!"

A cold snort escaped his lips! The Master appeared extremely displeased! The Demon Emperor stood below with his hands hanging down, his head kept low, never daring to look the Master in the eyes! Cold sweat had even broken out on his forehead!

"Even if one's cultivation reached the level of the Ten Kings of the Underworld, they would still be unable to penetrate the 'Yin and Yang Qi', and you think you can? Hmph!"

As he spoke, the Master seemed extremely furious! He suddenly stopped talking! The Demon Emperor's heart pounded as one, and for a long while, he did not dare to move a muscle!

"I heard from Qin Xiaofeng that you still haven't recovered the Underworld Ancient Book?"

Steadying his mood, the Master seemed to be trying his best to suppress his emotions, fearing that in his extreme rage, he might strike out and kill the Demon Emperor!

Upon hearing the words "Ancient Book", the final line of defense in the Demon Emperor's heart finally collapsed! Facing the Master's terrifying pressure and aggressive momentum, he bowed with trembling hands!

"Master! The ancient book was indeed in my possession before, but I do not know who stole it from the Demon Emperor Tomb!"

"Say no more, I knew that long ago! I am only asking you, is there any trace of the ancient book now?"

Interrupting the Demon Emperor, the Master's voice became even more severe, and an aura of slaughter filled the entire hall along with his words! Now, let alone the Demon Emperor, even the others felt a chill in their hearts!

"This... it still hasn't been found!"

Biting the bullet, the Demon Emperor finally told the truth! However, it was not as he had expected; the Master did not fly into a rage, but instead gave a cold laugh!

"Not found! Then keep looking for me! I will give you another hundred years; if you cannot find it, you know my methods!"

The hall was deathly silent! The breathing of everyone could be heard clearly, especially the Demon Emperor's; his breathing, heavy as an ox's, seemed as if it wanted to suck in all the air in the place!

Qin Xiaofeng stood to the side, glancing sideways at the Demon Emperor, his heart filled with great joy. Now, in the Great Underworld Mansion, only the Demon Emperor could match him; if the Demon Emperor fell, everything in the Great Underworld Mansion, aside from the Master, would belong to him! It could be said he was below one person, but above ten thousand!

But if the Demon Emperor recovered the ancient book, in terms of seniority and cultivation, the Master would absolutely not let him command the entire Great Underworld Mansion!

In fact, in the Great Underworld Mansion, the Master basically did not concern himself with these matters; whoever he chose could act on his behalf to manage all affairs within the Great Underworld Mansion!

"A hundred years!"

The Demon Emperor was even more terrified this time. Perhaps a hundred years was a long time for a mortal, but for a cultivator, a hundred years was but a fleeting moment! To find the ancient book in such a short time was easier said than done!

"Correct! A hundred years! If you feel your cultivation is insufficient, I can help you raise your strength to the Nascent Soul Late Stage in a short time! But no matter what, that book must be brought back to me!"

The Demon Emperor's tightly furrowed brows instantly relaxed! Raising his strength to the Nascent Soul Late Stage in a short time was exactly what he wanted! Having been in a rush to rebuild his physical body, the Demon Emperor's cultivation had been trapped at the Nascent Soul Middle Stage; for these years, there had been basically no progress. If he could reach the Late Stage, he would have a chance to break through to the Spirit Severing Stage!

When that time came, as long as he ascended to the Demon Realm, perhaps he would no longer be constrained by the Master! However, he would absolutely refuse to tell anyone else about these matters! Because only he knew that this Master was a powerhouse from a higher-level interface, and simply not something a Human Realm cultivator could contend with!

"Please rest assured, Master! I will definitely recover the ancient book!"

The Demon Emperor was full of confidence, as if the ancient book would automatically appear once his cultivation was raised! Nodding slightly, the Master shifted his gaze back to Qin Xiaofeng!

…………

Inside the Four Spirits Square Cauldron at the bottom of the Cold Pool, Zhang Nuo stood to the side quietly watching Su Haizhen. He saw her beautiful eyes tightly shut, and above her head, a cyan Nascent Soul was rolling incessantly. After a long time, the Nascent Soul finally steadied its form, and its two small hands pinched a Dharma seal! After chanting for a long time, it suddenly opened its pair of small eyes!

Where its gaze landed, it saw Zhang Nuo! A trace of joy appeared on the Nascent Soul's face! At this moment, Zhang Nuo also let out a long breath, and the tension on his face vanished completely!

A moment later, the Nascent Soul returned to Su Haizhen's body. Zhang Nuo rushed over, grabbed her frail body tightly, and asked repeatedly:

"How is it? How do you feel?"

Opening her eyes and looking at Zhang Nuo's excited expression, Su Haizhen smiled sweetly; that smile contained a sense of relief and immense happiness!

"The Nascent Soul is now stable! After cultivating for a few more months to let the cultivation solidify, it will be a complete success!"

Sitting cross-legged on the ground, the voice Su Haizhen used to speak now was clearly very weak, without a shred of strength, but it appeared there was nothing seriously wrong!

"It's all this Cold Pool's fault! Otherwise, such a mess wouldn't have happened!"

Zhang Nuo looked at his beloved's thin frame, feeling very uneasy in his heart. Originally, Su Haizhen's process of Shou Dan Jie Ying had been very smooth, but who would have thought that an accident would occur just as her primordial spirit was collecting the celestial Spiritual Qi!

Because they were at the bottom of the Nine Nether Cold Pool, the Spiritual Qi from the celestial phenomena could not penetrate the pool water to enter the Small Tripod for a time! As a result, Su Haizhen's Golden Core was already shattered, and if there were not enough Spiritual Qi to condense the Nascent Soul, she would perish in no time!

Fortunately, at the most critical moment, Su Haizhen activated several Dharma arrays prepared in advance, forcibly drawing the celestial Spiritual Qi into the Small Tripod, but due to the cold air, the celestial Spiritual Qi was greatly reduced! Finally, seeing that things were going poorly, Zhang Nuo utilized the Nine Dragon Sword Case.

Spiritual Qi gathered within the Small Tripod; the Spiritual Qi in this tripod was already very dense, and with the gathering of the Sword Box, it was, for a time, not much different from the Spiritual Qi of the celestial phenomena!

Borrowing this Spiritual Qi, Su Haizhen was barely able to condense the Nascent Soul, but the newly formed Nascent Soul was still relatively weak; as long as it was attacked by external forces, it would immediately dissipate!

Zhang Nuo, acting as her protector, exerted his powerful influence; he used his own spirit pressure to forcibly suppress the restless Spiritual Qi in the surroundings, and then used the pure Spiritual Qi gathered by the Nine Dragon Sword Case to continuously nourish Su Haizhen's Nascent Soul!

If not for his Sword Box, this attempt at forming the Nascent Soul would likely have ended in failure! And Su Haizhen's entire cultivation would have been completely wasted! It was even more likely she would have perished directly!

"Thank you!"

Blinking her eyes a few times, Su Haizhen did not know what language to use to thank Zhang Nuo; in the end, she only said two words!

"Is there any need for thanks between you and me? Get some good rest! In a few days, I will help you stabilize your cultivation!"

Seeing that his beloved was very tired, Zhang Nuo did not say much else, only comforting her to get a good rest! The months-long process of forming the Nascent Soul had truly exhausted Su Haizhen! Closing her eyes again, she entered a state of meditation.

The stone in Zhang Nuo's heart fell to the ground, and he turned his head to look at Xuan Jin, who was also cultivating. Ever since he had released it last time, the little fellow had not returned to the Spirit Beast Bag!

In the ten years, Xuan Jin had just sat there quietly, its body motionless. However, to Zhang Nuo's discerning eye, Xuan Jin's body had grown much larger, looking like a child of about eight or nine years old, and as for its cultivation, it had even risen to the strength of a Fourth-Rank Spirit Beast!

This sudden change left Zhang Nuo both surprised and delighted. It seemed his previous understanding was wrong; Spirit Insects did not only rely on devouring metal to raise their cultivation; strong and pure Spiritual Qi could also do it! It was just that when in the outside world, there was simply no such powerful Spirit Power as a foundation!

"Kid Zhang, you've really made a killing this time! Not only did you win the beauty, but the Spirit Insect's rank has also been upgraded!"

Chunyangzi had seen everything that happened before, and Xuan Jin's advancement, in particular, moved him the most. With Xuan Jin's advancement, the quality of the Mysterious Crystal Stone it produced would become higher and higher; when that time came, completely repairing the Nine Dragon Sword Case would absolutely not be a problem!

"Although all of this is good, Senior, don't forget, I am still at the bottom of the Cold Pool? How to get out is the most important problem!"

Furrowing his brows slightly, for these years, Zhang Nuo had been thinking of ways to leave the 'Nine Nether Cold Pool', but unfortunately, he had no leads!

"You silly boy! Why think so much! Raising your cultivation first is the right path! Some people won't have such an opportunity in their entire lives!"

Chunyangzi scolded with a laugh.

Zhang Nuo shook his head helplessly. In fact, Chunyangzi's words were not entirely unreasonable. Borrowing the dense Spiritual Qi of this place to raise his cultivation first was the priority; as for whether he could get out, that would depend on future opportunities! If he found a chance to escape the Cold Pool now, where else would he find such a good place for cultivation?

Furthermore, after his cultivation was raised, he and Su Haizhen could join forces, and it might be possible to forcibly break through the pool water and rush out to see the light of day again! However, Zhang Nuo did not hold much hope for this point! To break through the pool water and rush out, what level of cultivation would that require!

Tapping his head with his hand, Zhang Nuo did not want to think about it anymore! As soon as he thought about the problem of escaping this place, his head would ache! Better to raise his own strength first! Anyway, there was a beauty to accompany him here, the cultivation conditions were unparalleled, and it was a rare place to find for a time! Why not make good use of it?
