With the help of the Nine-Layered Pagoda, Mu Chen had already refined the 20,000 Fallen Origin Pellets. Furthermore, what made Mu Chen feel at ease was that as long as the Nine-Layered Pagoda was maintained by Spiritual Energy, it would continue to exist. So he didn't have to keep an eye on it, which saved him a lot of time.
()
Because he could seize the time that the Nine-Layered Pagoda was refining the Fallen Origin Pills to truly study the Nine Lightning Tribulation Visualisation Technique that he'd obtained in the Death Ruins.
In the cave, dense azure smoke was still spreading out. The strands of Spiritual Energy contained within the Spiritual Energy essence was something that even a Sixth Grade Sovereign would covet.
Mu Chen, on the other hand, quietly sat in the depths of the cave. His body was wrapped in thick green smoke, and his expression was as calm as an ancient well. He did not move at all, like a boulder.
After handing over the task of refining Spiritual Energy Essences to the Nine-Layered Pagoda, the Nine Lightning Tribulation Visualisation Technique that he had left in his mind appeared.
Rumble.
When the 'Nine Lightning Prison Visualisation Technique' appeared, a low and deep roar of thunder reverberated within Mu Chen's mind. The sound of thunder seemed to possess a strange magical power that caused one's thoughts to gradually become fuzzy.
However, to Mu Chen, the interference from the thunderous roar was completely ignored. He had refined the Nether Demon Heart Lightning, and that thunderbolt was formless and intangible. It relied on the thunderous roar to launch its attacks. Therefore, Mu Chen was practically immune to the interference from the sound wave.
He restrained his thoughts and scanned the Nine Lightning Tribulation Visualization Technique with his mind.
Instantly, an ancient voice slowly rang out amidst the rumbling thunder. That voice was the voice of a god.
It was filled with a majesty that could make even the heavens and earth tremble.
"The Nine Thunder Tribulation Visualization Art is divided into nine tribulations. Using one's will to form a thunder prison and suffer the endless pain of thunder. Using the thunder to temper one's will to the extreme, one will then attract the thunder tribulation!"
"The Lightning Tribulation is divided into nine tribulations, with each tribulation being stronger than the last. If all nine tribulations are overcome, it will be the day when this technique reaches the Great Accomplishment stage.
With a myriad of Battle Wills, they can fight Heavenly Sovereigns. "
An ancient voice.
As the words echoed in Mu Chen's mind, Mu Chen was shocked. He had passed all nine tribulations.
Could he easily control billions of Battle Wills?
That step.
Just how terrifying would it be?
Mu Chen was shocked in his heart. It was hard for him to imagine how powerful it would be. Currently, he was already struggling to control the Battle Wills of twenty to thirty thousand soldiers. Therefore, it was hard for him to imagine how earth-shattering it would be if he could control hundreds of millions of Battle Wills.
At that time, it would really be as the legend said.
Even when facing a pinnacle powerhouse like a Heavenly Sovereign in the Great Thousand World, he wasn't afraid.
If the path of a Battle Formation Master was cultivated to the pinnacle, one would be able to stand at the highest position in this world.
Calming the shock in his heart, Mu Chen started to immerse himself in the cultivation technique of the Nine Lightning Tribulation Visualisation Technique. This technique was extremely cryptic, and only those with a powerful will could understand it. If it was someone with a weak will, it would be tough for them to even read it.
But even if Mu Chen's will was stronger than an ordinary person, he still felt a stinging pain in his mind when he finished reading the Nine Lightning Tribulation Visualisation Technique. That feeling was even more tiring than controlling five troops in a battle.
Facing this reaction, Mu Chen inwardly smacked his lips. It was no wonder why there were so few Battle Formation Masters. Not to mention how rare the cultivation technique of will was, just reading it alone had a high requirement. Even if ordinary people obtained it, they probably wouldn't have the ability to cultivate it. With so many restrictions, it was no wonder why there weren't many Battle Formation Masters.
Although it was troublesome to read the Nine Lightning Tribulation Visualisation Technique, Mu Chen couldn't help sighing after he finished reading it. The cultivation technique of will was truly miraculous.
That's because if he wanted to cultivate the Nine Lightning Tribulation Visualisation Technique, he would have to visualise a lightning prison in his mind with his will entering it to be tempered by countless lightning bolts.
Using lightning to cultivate wasn't rare in the Great Thousand World, since many lightning-attributed cultivation techniques required this. But will was formless, to begin with, so how could lightning be used to temper it?
Therefore, it required one to visualize a lightning prison in one's mind and trap one's will within it. Then, one would use the visualized lightning to bombard one's will, causing the will to grow stronger and stronger under the repeated bombardment.
This cultivation technique was something that Mu Chen had never heard of in the past.
From a common point of view, the so-called visualization was actually similar to creating something out of thin air in a dream, and then using this non-existent thing to achieve the effect of cultivating one's mental strength.
Even with Mu Chen's composure, he was stunned for a long time before recovering from such a peculiar cultivation method. Shortly after, he couldn't help bitterly smiling. He truly didn't know which Ancestor was so abnormal to be able to create such an inconceivable cultivation method.
Besides that, if one wanted to cultivate this Nine Tribulation Lightning Visualisation Technique, then one's will had to possess a certain level of affinity with lightning. Because only when one possessed a sufficient level of affinity would one be able to visualise a lightning prison that truly possessed the effect of tempering one's body.
In the lightning prison, the lightning that would be visualised would be different. At the same time, only by visualising the lightning that he had the highest affinity with, would the effect of tempering be better.
Looking at this point, Mu Chen finally understood why he had such a high compatibility with the Nine Lightning Tribulation Visualisation Technique. It should be because he had once fused with the Nether Demon Heart Lightning.
When visualising the lightning prison, he could directly visualise the Nether Demon Heart Lightning. After all, he had once fused with the Nether Demon Heart Lightning, so the compatibility between the two didn't need to be mentioned. This would allow him to achieve twice the result with half the effort.
Furthermore, the most important thing was that the Nether Demon Heart Lightning was formless and intangible. It attacked with the sound of thunder, and from a certain point of view, it could be said to be rather close to will. If it could be used to temper one's will, the effect would probably be very good.
Thinking of this, Mu Chen couldn't help feeling lucky. Looks like the Nine Lightning Tribulation Visualisation Technique was indeed extremely suitable for him. No wonder he was chosen.
However, visualising the lightning prison didn't mean that one could casually visualise it in one's mind. It required various complicated and miraculous methods, and the most difficult aspect was to truly retain the visualised lightning prison in one's mind, and not make it disappear after visualising it. Otherwise, one would have to visualise the lightning prison again every time they cultivated. At that time, it was likely that they wouldn't be able to cultivate at all.
Wanting to retain the visualised object also involved various factors. The degree of difficulty made even Mu Chen feel a headache when he saw it. For the first time, he felt that the path of a Battle Formation Master wasn't something that one could casually step onto.
However, at this point, no matter how impossible it was, Mu Chen clearly couldn't give up. It wasn't easy to obtain the Nine Lightning Tribulation Visualisation Technique. If he were to give up on it like this, it would truly be a waste of a treasure.
With such thoughts in mind, Mu Chen no longer hesitated. Once his mind gradually calmed down, he tightly guarded his mind. Just like what the Nine Lightning Tribulation Visualisation Technique had said, he gradually emptied his mind, leaving not the slightest bit of distracting thoughts.
This state of emptiness lasted for an unknown period of time. At a certain moment, Mu Chen's mind had truly entered a state of emptiness. That emptiness had even made him forget himself. This step was also extremely dangerous, because according to what the Nine Lightning Tribulation Visualisation Technique had said, if he completely forgot himself at this step, his will would become mindless, and a mindless will would unknowingly dissipate. This dissipation was true dissipation. Once his will dissipated, perhaps Mu Chen would never be able to wake up again in this lifetime.
But fortunately, Mu Chen was already prepared. When his mind gradually turned blank, the consciousness hidden in the depths of his will started to awaken. It was a self-suggestion to wake him up.
When he regained control of his will, Mu Chen started to visualise.
Rumble!
In his empty mind, there seemed to suddenly be the roar of thunder. Darkness spread out at this moment, and thunder rumbled within the darkness.
With the roar of thunder, there should be lightning.
As Mu Chen's will flickered, it was as if he had started to create a world. If he said that there should be lightning, then there should be lightning flickering within the darkness.
If lightning appeared, then there should be lightning.
Rumble!
Lightning flickered, but just when Mu Chen was about to visualise lightning, the roar of thunder in his mind abruptly intensified. As the rumbling noises resounded, Mu Chen was forcefully ejected from this state.
When his will was ejected from his mind, Mu Chen's consciousness recovered and all the information flooded into his mind. He helplessly flung his lips. His first attempt to visualise the lightning prison had clearly ended in failure. The visualization of the lightning prison was indeed not as easy as he had imagined.
However, Mu Chen wasn't the slightest bit depressed about his first failure. After all, if the lightning prison could be so easily visualised, then he would be underestimating the cultivation of a Battle Formation Master.
"Since I've failed, then let's continue."
Mu Chen smiled inwardly. Without any hesitation, he calmed his heart and emptied his mind, entering into a blank state once again.
Since the first attempt was useless, then he would try ten times, a hundred times, or even a thousand times. He refused to believe that he wouldn't be able to visualise the lightning prison after a thousand failures!
Nine Lightning Tribulation Visualisation Technique, I'm going to waste my time with you!
