Chapter 515: Demon Refining Pool

"Palace Master, this method of yours is truly effective!"

Walking all the way into the room, Hu Bao finally released the hand he had been gripping onto Zhang Nuo, and then said excitedly to the green-clad young girl!

"It seems the technique passed down from the Demon Realm is correct! What is your name, human boy?"

The young girl's expression was calm this time, as if everything were within her expectations; as her beautiful eyes shifted, she looked at Zhang Nuo.

"This one is Zhang Nuo!"

Standing properly to one side, Zhang Nuo answered cautiously!

"En! A good name! A promise worth a thousand gold! This fits the hypocrisy of you humans perfectly! You still have some use to this Palace Master for now; if you are willing to cooperate, you can still survive! If you disagree, you die immediately!"

Listening to the young girl's words, Zhang Nuo felt that although her voice was soft and pleasant, the killing intent within her words was not concealed in the slightest!

"I am willing!"

Zhang Nuo gave his answer directly, almost without hesitation!

"That is best! From now on, you are responsible for injecting Purple Lightning Wild Thunder into the Demon Refining Room; however, remember, the amount each time must not be too large! If a single demon dies in the pool, I will have you pay with your life!"

The young girl said.

Zhang Nuo felt his head buzz, and he lamented bitterly in his heart! Could the life of a single demon be more precious than his own? Not daring to say any more nonsense, he could only nod, putting on a very submissive appearance!

"Whoosh!"

Just when Zhang Nuo was fully convinced that he was finally safe, the green-clad young girl suddenly reached out and cast a Dharma technique, which went directly into his body. Instantly, Zhang Nuo felt as if his entire body had fallen into a raging fire! His internal organs were scorched through and through!

His body curled into a ball, rolling back and forth on the ground! Even though he had tempered his body with Red Glow Fire, this pain was still hard to endure! After a moment, the pain slowly began to fade.

Crawling up from the ground, a green light flashed within the pupils of Zhang Nuo's eyes!

"I have planted this Palace Master's unique Restriction inside your body! Do not attempt to play any tricks, or you will suffer even more than you are now!"

Lifting one snow-white jade foot, the young girl said nonchalantly:

"Oh, right! I almost forgot! If you attempt to use Spirit Power to drive a Magic Treasure, then the Spirit Power within your body will instantly turn into flames, burning your body to ashes! If you don't believe me, you can try it now!"

A chill rose from the bottom of Zhang Nuo's heart! What the young girl said could not be false! Because just now, under his own internal inspection, he saw dots of green light hidden everywhere inside his body! As soon as any Spirit Power was emitted, the green light would transform into a type of green flame, continuously scorching his body! Until the output of Spirit Power stopped, the green light would change back to its original appearance!

This was the first time Zhang Nuo had seen such a bizarre Restriction. If Chunyangzi and Baji Laomo were still around, they might have been able to explain it, but now that the two remained in the Human Realm, it was impossible for them to come and help him!

With a pained expression, Zhang Nuo looked up at the young girl; he did not expect that beneath her beautiful countenance, her heart would be more vicious than a scorpion! How did she think of such an overbearing Restriction?

"Since you have no questions, then go to the Demon Refining Room and get to work!"

Looking at Zhang Nuo's somewhat stubborn and angry face, the young girl then ordered. The so-called Demon Refining Room was that underground hall filled with Demon Refining pools!

Zhang Nuo was taken back there by a small demon! From this day on, Zhang Nuo began a life of misery, continuously unleashing Purple Lightning Wild Thunder every day to inject into the Demon Refining pools! Those small demons in the pools, after feeling the benefits of the purple lightning, waited there on time almost every day!

Because his internal Spirit Power was restricted, Zhang Nuo had no way to cultivate! Furthermore, there were always a few small demons guarding him, so he didn't even have a chance to escape!

If the miserable state Zhang Nuo was in now were seen by those cultivators in the Human Realm, they would never choose to ascend even if they were to die! A figure who could summon wind and rain in the Human Realm was actually worse than a servant upon reaching the Immortal World!

"Xuan Jin, find a chance to slip out! See what the situation is with this palace!"

In the moment he turned around, Zhang Nuo discovered no small demons were watching him, so he immediately sent a voice transmission to Xuan Jin! With just a light 'en', Xuan Jin found an opportunity, transformed into a Golden Light, and submerged into the ground!

It was fortunate that he had Xuan, otherwise, Zhang Nuo would be trapped in this Demon Refining Room until the Purple Lightning Wild Thunder in his body was exhausted and he was of no use, only to be killed by these demon cultivators in the end!

Two months later, when Hu Bao stood before the green-clad young girl, his large black face smiled like a flower! His mouth could not close for a long time!

"Palace Master! The Purple Lightning Wild Thunder from this kid Zhang Nuo is truly too effective! Now those small demons in the Demon Refining pools are each full of vigorous vitality; if things continue like this, our Demon Beast Tide plan can be implemented ahead of schedule!"

"Hmph! That bunch of fellows in the Immortal Domain! They have been riding on our heads for so many years; they must pay a price! Is Zhang Nuo still obedient?"

A rare look of anger appeared on the young girl's face, with layers of killing intent at the corners of her eyes and brows!

"Of course he is obedient! Now, besides injecting Purple Lightning Wild Thunder into the Demon Refining pools every day, he just sits quietly in the corner waiting to die!"

Hearing Hu Bao's words, the young girl rolled her eyes; based on her many years of experience, Zhang Nuo was not a human cultivator who gave up easily. To have such a performance was truly beyond her expectations!

"Do not take this lightly; that kid is not that simple! If my grand plan is ruined because of him, the loss will outweigh the gain!"

After the young girl gave a few instructions, she turned and left! Hu Bao looked at the young girl's back and swallowed a mouthful of saliva! Even her back was so enchanting! He could only think about it, not daring to take any actual action. Regarding the young girl's cultivation, Hu Bao was all too clear; even if he were to join forces with all the demon beasts in this Huan Shou Gong, he was afraid he would not be the young girl's match!

Zhang Nuo was currently sitting in a corner of the Demon Refining Room. Taking advantage of the time when no demon cultivators were paying attention, he communicated with Xuan Jin through his mind. Through Xuan Jin's continuous traveling underground during this period, he finally managed to understand the entire Huan Shou Gong a bit better!

The surface area of this palace was far smaller than the underground area. Besides this Demon Refining Room, there were many underground secret chambers, among which there were over a thousand demon cultivators who had reached the Transformation Stage, and there were also over a dozen high-rank cultivators present!

While listening to Xuan Jin's news, Zhang Nuo observed the surrounding demon cultivators. Over the two-plus months, these demon cultivators saw that Zhang Nuo did not resist, so they relaxed their vigilance toward him a little; he only needed to inject Purple Lightning Wild Thunder into the Demon Refining pools on time.

Having grasped the strength of the entire Huan Shou Gong, Zhang Nuo began to try to resolve the Restriction planted in his body by the green-clad young girl! After trying several methods, he had not succeeded, and finally, he thought of the Jingming Divine Tree!

He tried wrapping the green light spots on his palms with the branches and leaves of the Divine Tree! Unexpectedly, after a few days, more than half had been eliminated! This time, hope rose in Zhang Nuo's heart once again! It seemed his guess was not wrong; the technique used by that green-clad woman was also a type of wood-attribute technique!

Since the Divine Tree could resolve it, he only needed time, and there would eventually be a time when the Restriction could be safely removed. In order not to attract others' attention, Zhang Nuo specifically used the green color of the Jingming Divine Tree to cover the places in his body where he had resolved the Restriction, especially his own pair of eyes!

After being hit by the girl's Restriction, green light had been flashing in his pupils; if the green light suddenly weakened or disappeared, it would definitely arouse the suspicion of the demon cultivators! He extracted the essence from a leaf of the Divine Tree and, through the circulation of his own blood, transferred it to his eyes! In this way, no matter who looked, there would always be green light flashing in Zhang Nuo's eyes!

After solving the problem of being discovered, Zhang Nuo let the roots of the Divine Tree spread throughout his entire body! He began to resolve the Restriction in his body one by one!

On the other hand, Zhang Nuo began to study these Demon Refining pools!

Through two months of observation, Zhang Nuo discovered that these Demon Refining pools themselves had nothing special about them; it was just that when the pools were built, some Fowen from the Demon Realm were added around them!

The greatest mystery lay in the green liquid! He had more than once used his fingers to touch that liquid, only to feel a large amount of pure life-source power rippling within the liquid, and furthermore, some bizarre demon power was slowly flowing from the green liquid into the bodies of the small demons being cultivated!

In this way, the growth speed of these small demons would be extraordinarily fast! Once they became complete forms, their strength would not be below the Eighth Rank!

Zhang Nuo had never heard of such a unique method for nurturing high-rank demon beasts! He carefully memorized the structure of the Demon Refining pools, and then whenever he had a chance, he would let the Jingming Divine Tree absorb the green liquid from the pools!

A month later, the Jingming Divine Tree was actually much stronger than before, and it loved to absorb the green liquid in these pools. In order not to arouse suspicion, Zhang Nuo did not boldly steal the green liquid, but only took a very small portion from multiple pools! In this way, by accumulating little by little, the Divine Tree did indeed receive quite a few benefits!

Three years later, Zhang Nuo had already completely resolved the Restriction in his body, and at the same time, those small demons in the Demon Refining pools had also grown up rapidly!

The demon beasts that were originally the size of infants had now all transformed into human forms, only their intelligence had not yet been fully opened, remaining in a state of chaos!

Every time Hu Bao came to the Demon Refining Room, he would show a joyful expression; these demons seemed to be extremely important to Huan Shou Gong!

At the same time, in Gongyue City of the Immortal Domain! Kong Mu looked at the several cultivators in front of him with an ugly expression, unable to say a word for a long time!

After receiving the message sent back by Zhang Nuo, he immediately transmitted this news to the Sixteen Chambers of the Immortal World. After long discussions by the cultivators there, by the time the news was transmitted back, it was already several months later!

Having received permission from above, Kong Mu sent people to support the squad where Zhang Nuo was located, but when the people arrived, the Stationing Tower was empty; where was there any sign of Zhang Nuo?
