Time quietly flowed in the Demonic Lightning Abyss, which was filled with violent roars of thunder.
Rumble!
Within the Demonic Lightning Abyss, berserk thunderous roars never showed the slightest sign of stopping. In the depths of the abyss, there were over a thousand figures seated in the air, with pitch-black lightning constantly shuttling back and forth like pythons.
Those silhouettes were as still as boulders, allowing the Demonic Earth Lightning to strike them, but their silhouettes did not move.
They formed the same seals with their hands and traces of pitch-black lightning quietly entered their bodies through their pores, refining their flesh and bones.
A few hundred meters away from them, Mu Chen was also seated in the sky. However, his eyes were slightly closed at this moment. He extended his hand out and a dilapidated stone tablet that had shrunk down by a lot quietly stood in his palm.
His eyelashes moved at this moment. After which, his tightly shut eyes slowly opened. He was a little absent-minded as he stared at the stone tablet in his hand. His eyes were filled with astonishment.
In this period of time, while he was refining the physique of the Jiu You's Guard, the rest of his time was spent on the Supreme Demon Heart Scripture that was recorded in the dilapidated stone tablet.
After a few days of comprehension, he had some basic understanding of the Supreme Demon Heart Scripture. Just as Jiu You had said, the Supreme Demon Heart Scripture on the stone tablet wasn't complete.
Furthermore, the Demon Heart State that Jiu You had mentioned did exist. However, the Demon Heart State was divided into three realms, the Lesser Demon Heart State, Greater Demon Heart State, and the most perfect Demon Heart State.
According to what Jiu You had said, the Palace Master of the Lightning God Palace had probably cultivated the Demon Heart State of the Supreme Demon Heart Scripture to the Perfection Realm. Otherwise, it would be impossible for him to confront a genuine Heavenly Sovereign with his strength that was only half-a-step into the Heavenly Sovereign Realm.
Looking at the incomplete Supreme Demon Heart Scripture, even if he cultivated it to its limit, he would only be able to reach the Great Demon Heart Realm. If he wanted to reach the Great Demon Heart Realm, he would need the complete Supreme Demon Heart Scripture.
However, with Mu Chen's current strength, even if he obtained the complete version of the Supreme Demon Heart Sutra, he would definitely not be able to cultivate it successfully. Therefore, he did not feel that it was a pity.
Just the first two levels were enough for him to grit his teeth and train bitterly.
"What a pervert …"
Mu Chen recalled the ancient information that lingered in his mind. In the end, he involuntarily let out a long sigh. His expression was a little strange. This was because based on his comprehension, he already knew just how much of an abnormal training was needed in order to form this Heart Demon State.
In order to form the Heart Demon State, one must first form a Heart Demon Seed. This Heart Demon Seed required the Nether Demon Heart Lightning to attack one's heart countless times. After which, one would allow the Nether Demon Heart Lightning's power to seep into one's heart. In the end, it would slowly gather in the depths of one's heart until it successfully transformed into a Heart Demon Seed.
In the view of many people, this kind of training method was practically seeking one's own death. No matter how one trained, the heart was the weakest part of the human body. A slight injury would result in a heavy injury or even death. Who would dare to use something as overbearing as the Nether Demon Heart Lightning to attack one's heart?
If there was even the slightest mistake, even one's heart would explode when the sound of thunder rang out.
Even if an ordinary person obtained the Supreme Demon Heart Scripture, they would not dare to train in this kind of training method.
Mu Chen gripped the stone tablet as he involuntarily smacked his lips. A sliver of hesitation flashed across his eyes. However, this hesitation only lasted for an instant before it was suddenly dispersed by the unswerving determination that surged out.
He had promised that girl that he would become an unrivalled expert. There were far too many geniuses in this world. He also understood that he would never reach that step by relying on so-called talent.
A true expert would have nothing to fear.
Therefore, he was not afraid of anything!
A brilliant smile rose on Mu Chen's youthful and handsome face. Shortly after, his gaze abruptly turned sharp as he slowly closed his eyes. With a command of his mind, the Spiritual Energy that had fused with the Nether Demon Heart Lightning circulated along his meridians. In the end, it turned into a current and charged towards the location of his heart like a bolt of lightning.
Hiss!
A sharp thunderous roar that was like a ghost's howl abruptly spread out from his heart. The thunderous roar resounded within Mu Chen's body, causing his five viscera and six bowels to tremble. It was so much so that even the flow of his blood was obstructed.
Poof!
A mouthful of blood gushed out from Mu Chen's mouth as his face instantly turned pale. Veins crawled on his face, making him look extremely bizarre. He heavily panted as he held onto his chest, enduring the heart-tearing pain.
The thunderous roar felt as if it was tearing his heart apart.
"Damn it."
Mu Chen couldn't help cursing due to the intense pain. The Supreme Demon Heart Scripture was truly worthy of the word 'Demon'. It was filled with evilness. This was the first time that he had encountered such a self-harming cultivation method.
Huff.
He panted for a long time, before his body gradually calmed down. Shortly after, he clenched his teeth and controlled the Nether Demon Heart Lightning to charge towards his heart.
Poof...
Poof...
In the darkness of the Demonic Lightning Abyss, the youthful silhouette was constantly vomiting blood. However, he was still enjoying it. The bizarre situation had caused some of the Jiu You Guards to be dumbfounded. However, they did not dare to say anything and could only close their eyes to cultivate.
Thus, nearly half a month's time swiftly passed with mouthfuls of blood and violent thunderous roars.
Unknowingly, it had been an entire month since Mu Chen and the rest entered the Demonic Lightning Abyss to cultivate. In this month, the Expedition War of the Great Heaven Domain had also become more intense.
The Great Heaven Domain was, after all, a top-tiered force in the Northern Region of the Greatlaw Continent. Thus, their strength was naturally stronger than the Hundred Battles Domain. Therefore, when the war broke out, the Hundred Battles Domain had been steadily retreating. Although they would occasionally launch a counterattack, it still couldn't affect the overall situation.
However, the Hundred Battles Domain wasn't a pushover. Along with their defensive line constantly retreating, the power gathered grew stronger. Therefore, the offensive speed of the Great Havenlaw Domain had also started to slow down. It was no longer as easy as it was at the beginning, where they could easily crush the Great Havenlaw Domain.
Facing this situation, the Great Heaven Domain had also started to gather their forces and no longer spread them out. That's because the higher-ups of the Great Heaven Domain knew that the core of the Hundred Battles Domain was the Myriad Swords Valley, the Demonic Corpse Sect, and the Great Compassion Sky.
Since the beginning of the war, the three most powerful forces in the Realm of a Hundred Battles had yet to make a move. Only by defeating them would the Realm of a Hundred Battles be completely destroyed.
Therefore, the Great Heaven Domain had also started to gather their forces, preparing to defeat the three top-tiered forces and end the war, spreading the fame of the Great Heaven Domain.
Facing the Great Heaven Domain's all-out attack, the Myriad Swords Valley, the Demonic Corpse Sect, and the Great Compassion Sky had also gathered their forces, preparing to launch a decisive battle against the Great Heaven Domain.
Thus, countless gazes were directed over from the Northern Region. After all, with the status of the Great Havenlaw Domain and Hundred Battles Domain, they could be considered as heavyweights in the Northern Region. The outcome of this battle would have a considerable impact on the entire Northern Region.
Therefore, before the decisive battle had even begun, it had already attracted the attention of the four Fang Yun's. Numerous gazes were cast over from all directions.
…
While the outside world was in an uproar because of the upcoming decisive battle, Mu Chen was still quietly sitting in the Demonic Lightning Abyss. His body would slightly tremble from time to time, and his handsome face would also twitch.
That was because of the Nether Demon Heart Lightning striking his heart.
However, compared to before, when he would spit out a mouthful of blood every time he struck, it was clearly much better. It seemed that he had gradually adapted to it.
Mu Chen's body trembled for a long time, before his tightly shut eyes slowly opened. He lightly exhaled a mouthful of air and rubbed his forehead in exhaustion.
It could be said that he had suffered a lot during this period of time.
This damnable Supreme Demon Heart Scripture really wasn't meant for humans to cultivate.
Fortunately, there was some effect after suffering so much. Although he had yet to refine a Heart Demon Seed, he could sense that there was already the power of the Nether Demon Heart Lightning gathering in the depths of his heart. As long as he continued to train like this, he should be able to refine a Heart Demon Seed.
Mu Chen gently patted his chest, before raising his head to look at the Jiu You Troop nearby. His brows slightly twitched, because he realised that every single Jiu You Troop had lightning runes vaguely appearing on their chests.
The number of lightning runes varied, and even Qiu Shan and the rest, who were the most powerful among them, showed signs of forming their fourth lightning rune. Such a speed was extremely swift.
However, Mu Chen also understood that the speed of Qiu Shan and the rest's Lightning God Physique cultivation would greatly slow down. There was still a long way to go before they could reach the Ennea Rune Lightning Body.
But it was enough for now.
Mu Chen stood up and waved his sleeve. The Demonic Earth Lightning that was bombarding the Jiu You Troop from all directions immediately fled and tunnelled into the stone walls.
The Jiu You Troop also opened their eyes one after another at this moment. Black lightning flashed in their eyes.
"Congratulations to all of you," said Mu Chen with a faint smile. "You've successfully cultivated the Lightning God's Physique."
Swish!
All the Jiu You Troop abruptly stood up at this moment and knelt down on one knee towards Mu Chen. Their orderly voice caused the thunder in the depths of the Demonic Lightning Abyss to pause.
"Thank you commander!"
Mu Chen waved his hand. He could sense the overall change in the aura of the Jiu You Troop, which made him rejoice in his heart. His efforts were not in vain.
"It's about time to leave." Mu Chen raised his head and muttered to himself.
Just as Mu Chen muttered to himself, the Jiu You Troop's voice suddenly resounded beside his ear.
"Prepare to move. The Great Heaven Domain is about to fight the Hundred Battles Domain."
