Chapter 413: The Mysterious Beam of Light

At this moment, the Demon Emperor had been forced into a dead end. Facing the immense power unleashed by Zhang Nuo's activation of the "Four Spirits Square Cauldron," he had no path of retreat left!

Ahead, the four ancient thunder-controlling sacred beasts, condensed from arcs of electricity, roared ferociously; it looked as though they would charge forward the moment Zhang Nuo gave the order!

The Demon Emperor sighed slightly, then his hands became covered in pure Demonic Qi, and he slammed them toward the "Heavenly Demon Cauldron" in front of him! With a "humming" vibration, the small tripod's size surged more than several dozen times! At the same time, the Demon Emperor's figure leaped directly into the tripod!

This sudden turn of events not only shocked Zhang Nuo, but even Qin Xiaofeng and the others below were greatly alarmed! Could this be the ultimate mystery of the "Heavenly Demon Cauldron"? However, it didn't seem to be anything special!

Just at this moment, Zhang Nuo moved his Divine Sense, and the four sacred beasts formed by electric arcs pounced toward the enlarged "Heavenly Demon Cauldron"!

The four beast heads, accompanied by a biting wind and low, angry roars—although everyone knew the four sacred beasts were fake, the feeling they gave was extremely real! It was as if they were truly existing at this moment!

Yet the Demon Emperor remained hidden inside the Heavenly Demon Cauldron and never came out, and the small tripod itself showed no changes. Zhang Nuo watched intently as the four sacred beasts struck the Heavenly Demon Cauldron. Following a series of thunderous booms, countless electric arcs wrapped around the Heavenly Demon Cauldron.

The surrounding Demonic Qi and electric arcs emitted a harsh "squeaking" sound, but this earth-shattering strike from Zhang Nuo seemed to have caused no damage to the "Heavenly Demon Cauldron" at all! It was as if a child were tickling an adult!

This shock was no small matter. Zhang Nuo had used the "Four Spirits Square Cauldron" to defeat many opponents, but he had never imagined it would have this effect against the Demon Emperor's "Heavenly Demon Cauldron"!

It was not only Zhang Nuo who was surprised; Qin Xiaofeng stood with his hands behind his back, a strange look flashing in his eyes. He had intended to use Zhang Nuo's attack to see what mysteries lay within the Demon Emperor's Heavenly Demon Cauldron! He had not expected this result!

Just as everyone was shocked, a figure flashed out from the Heavenly Demon Cauldron. The Demon Emperor stood steadily on the rim of the tripod, his pair of eyes, which radiated a sinister aura, filled with disdain!

"This is the 'Four Spirits Square Cauldron'? It is truly this useless!"

The Demon Emperor seemed to know something about the Four Spirits Square Cauldron, yet he did not state it clearly. His expression tightened as he said coldly:

"Zhang Nuo! Your doomsday has arrived today! Prepare to die!"

Zhang Nuo, his face full of astonishment, felt his heart stir upon hearing the Demon Emperor's words. The next moment, he moved his Divine Sense slightly and recalled all his Magic Treasures into his body! His figure turned into a streak of light and fled toward the distant sky!

This was not because Zhang Nuo was cowardly! It was because this place was truly greatly disadvantageous to him. If he could have severely injured the Demon Emperor with the strike from the Four Spirits Square Cauldron earlier, perhaps he would have had a chance to fight, but now, having used the Spirit Power of two Divine Seas without even harming a single hair on the Demon Emperor, continuing to fight would only lead to death!

Most terrifying of all, Qin Xiaofeng had not yet made a move. If this mysterious fellow were to launch a sneak attack from the sidelines, the consequences would be unimaginable! After weighing the pros and cons, Zhang Nuo did not persist but decisively chose to flee! The direction he fled was not toward Zhou Huizheng, but in the completely opposite direction!

Zhang Nuo did this because he did not want to bring trouble to Zhou Huizheng and the others! Seeing Zhang Nuo flee, the Demon Emperor furrowed his brows and cast his gaze toward Qin Xiaofeng in the valley!

"Daoist Qin! Come with me to pursue Zhang Nuo! This child cannot be let go!"

Hearing the Demon Emperor's words, Qin Xiaofeng was also tempted. Their goal all along had been to find the eggs of the "Mysterious Heaven Spirit Insect," and Zhang Nuo was the only clue! Perhaps if they caught Zhang Nuo, they would obtain very valuable information!

Thinking of this, Qin Xiaofeng was just about to follow the Demon Emperor in pursuit, but at this moment, an unexpected thing happened! Behind him, the few cultivators who were breaking the Restriction all revealed looks of joy simultaneously!

"We are about to succeed! Let's put in more effort!"

One of the cultivators had a face full of wild joy, and the Array Disk in his hand flashed with rapid light! Qin Xiaofeng looked back and saw that the Restriction at the entrance of the Cave Abode was becoming thin, and at the same time, a faint light was coming from the deepest part of the Cave Abode. The moment he saw the light, he suddenly felt uneasy!

With a shift in his thoughts, Qin Xiaofeng suddenly shouted loudly:

"Get out of the way!"

But before his voice had even faded, a heaven-shattering roar came from inside the Cave Abode, and following that, a mysterious white beam of light, at least a zhang thick, shot out from the interior of the Cave Abode, skimming along the ground!

Qin Xiaofeng's reaction was extremely swift; without any visible movement of his body, he transformed directly into a streak of escape light and shot toward the high sky! As for those few cultivators breaking the array, before they could even react to what was happening, the massive beam of light had already reached the entrance of the Cave Abode!

Boom!

With a loud bang, the mysterious beam of light struck the Restriction in front of the Cave Abode. The moment the two made contact, the Restriction was torn apart as if it were rotten wood! At the same time, a massive force surged out from within the Cave Abode instantly! The few cultivators who had just been breaking the array were directly smashed to pieces by the power of the beam!

The beam of light did not stop there but continued to charge straight ahead! Its speed was so fast it was staggering! In the blink of an eye, a deep trench appeared on the ground in front of the Cave Abode, extending all the way to the entrance of the valley!

Anything in this straight line was spared by nothing; even those earth giants were turned into dust! A few disciples of the Great Underworld Mansion who did not manage to dodge in time were wiped out by the beam!

This shocking turn of events caused Qin Xiaofeng to knit his brows tightly. It seemed that there must be a major secret inside this Cave Abode, otherwise, it would not have such a ruthless Restriction! The owner of the Cave Abode clearly intended to use this mysterious beam of light to kill anyone who broke the Restriction!

Thinking of this, Qin Xiaofeng gave up on Zhang Nuo and flew directly toward the inside of the Cave Abode! By the time Jin Buhuan came to his senses, Qin Xiaofeng had already disappeared into the Cave Abode.

After a moment of thought, the old man also flickered his figure and dived into the Cave Abode! The Demon Emperor had wanted to pursue Zhang Nuo, but seeing these two rush into the Cave Abode regardless of everything, he also suspiciously withdrew the "Heavenly Demon Cauldron" and then rushed toward the Cave Abode as well.

The people of the Great Underworld Mansion had spent several full days breaking into this Cave Abode; judging solely from the surface Restriction, the things inside were no small matter! Therefore, none of the three wanted to give up the chance to obtain the treasures! Especially the Demon Emperor; if he wanted to break away from the Great Underworld Mansion, he needed sufficient strength! And the most effective way to increase strength, besides raising his cultivation, was to obtain a few powerful Magic Treasures!

After Zhang Nuo flew for several thousand miles in one breath, seeing that the Demon Emperor was not pursuing, he finally felt slightly relieved! However, there was one thing that still left him unable to understand! Why did the most powerful attack of the "Four Spirits Square Cauldron" have no effect on the "Heavenly Demon Cauldron"! Could it be that the "Four Spirits Square Cauldron" was truly inferior to the "Heavenly Demon Cauldron"?

Thinking about it carefully, Zhang Nuo felt this was unlikely; as both were Ancient Treasures, even if there were a difference, it wouldn't be so vast!

"Senior! You saw the battle just now; what is the reason for this?"

Forced by necessity, Zhang Nuo finally sought the answer from Chunyangzi!

"Hey! I say, Zhang lad, have you discovered the difference in the 'Heavenly Demon Cauldron'?"

Without answering Zhang Nuo immediately, Chunyangzi asked in return. Lowering his head to ponder for a moment, Zhang Nuo shook his head slightly and said:

"I haven't discovered anything else, only that the defensive power of this 'Heavenly Demon Cauldron' is super strong! I fear that even if the 'Heaven-Turning Seal' were still here, a full-force strike would not cause it any damage!"

"That is correct. The greatest advantage of the Heavenly Demon Cauldron is its strong defensive power! And what drives it and allows it to exert such powerful defense is Demonic Qi. The reason you couldn't break the Heavenly Demon Cauldron is that you failed to break the Demonic Qi! In other words, you did not destroy its root!"

Chunyangzi said with a faint smile.

"Senior, what do you mean by this? Demonic Qi is an existence equal to Spiritual Qi; even if my cultivation were higher, it would be impossible to break the Demonic Qi all at once, right?"

Zhang Nuo was greatly puzzled; using Demonic Qi to drive a Magic Treasure was no different from using Spiritual Qi to drive a Magic Treasure!

"Zhang lad, do you still remember the question Baji Laomo asked you back then?"

"Which one?"

Baji had asked Zhang Nuo many things, and for a moment, he did not know what Chunyangzi was referring to.

"It was asking you if you had anything to restrain demonic creatures!"

Reminded by Chunyangzi, Zhang Nuo did recall that when dealing with the Extraterritorial Heavenly Demons, Baji Laomo had indeed asked that!

"Senior, you mean to say that as long as I find something that restrains demonic creatures, I can break the Heavenly Demon Cauldron!"

With one word, the dreamer was awakened; Zhang Nuo's mental knot was instantly untied!

"Correct! Although the 'Four Spirits Square Cauldron' in your hand is indeed an Ancient Treasure, this tripod seems to be missing one thing! Therefore, its power is naturally greatly reduced! By using your own weaknesses to attack the enemy's strengths, you have no reason to win! There is an ancient thunder-controlling sacred beast on each of the four sides of the small tripod. If you can find the 'Purple Lightning Wild Thunder' that specifically restrains demonic creatures and fuse it into the tripod, its power will naturally increase greatly, and the effect will be completely different when you use that move to attack the Heavenly Demon Cauldron again!"

Chunyangzi spoke incessantly, yet the light in Zhang Nuo's eyes grew increasingly intense! He had come to the First Immortal Mountain this time precisely for the "Purple Lightning Wild Thunder!" However, how could such a heaven-defying wonder be found so easily!

"Senior, is it only the 'Purple Lightning Wild Thunder' that can work?"

"That is not the case. There are many things in heaven and earth that restrain demonic creatures; it is not just the Purple Lightning Wild Thunder. As long as it is something of the thunder element, I believe the Four Spirits Square Cauldron can exert its most powerful might!"

Fearing that Zhang Nuo would fall into a misconception, Chunyangzi explained again.

"Since that is the case! Then I will go and try my luck!"

Having made up his mind, Zhang Nuo's desire for the "Purple Lightning Wild Thunder" grew even stronger. Finding this thunder was not only related to being able to increase the power of the "Four Spirits Square Cauldron," but the greater benefit lay in the future when he would undergo the "Heavenly Demon Tribulation!"
