Whoosh!
Two dazzling streaks of light streaked across the horizon like meteorites, causing space to collapse in their path with a destructive fluctuation that caused the entire heavens and earth to tremble.
The two streaks of light did not resort to any other means, but streaked across the horizon in a barbaric manner before clashing together.
Boom!
Boundless spiritual light wreaked havoc in the sky from the collision. Within a few tens of thousands of miles, the clouds in the sky were instantly destroyed and the azure sky was empty.
Although the two of them were fighting in the heavens, there were still aftershocks that spread out, causing the land to tremble and the earth to crack.
Many Earth Sovereigns felt their scalps going numb. Even the aftershock of such an attack wasn't something they could endure.
Boom!
Under countless shocked gazes, a dazzling spiritual lustre burst out in the sky and the two silhouettes instantly flew out with the space behind them collapsing.
Mu Chen retreated a few thousand feet and his body lightly trembled. His body, which had completely turned into Spiritual Energy, was like a dazzling crystal. Ripples undulated on the surface of his body, which had dissolved the terrifying energy.
On the other hand, the Profound Sky Ancestor only retreated roughly a thousand feet. His Spiritual Physique was different from Mu Chen's. The surface of his body was engraved with stars that easily resolved the energy that invaded his body.
In this confrontation, the veteran Heavenly Sovereign, the Profound Sky Ancestor, had the upper hand.
But even so, the Profound Sky Ancestor's face had turned grave. Through this confrontation, he could sense that although Mu Chen's Heavenly Sovereign Spiritual Physique had just been formed, it was more solid than he had expected. Evidently, the latter had a deep foundation and did not rely on luck to soar into the heavens.
As Patriarch Dark Heaven's expression turned serious, Mu Chen looked pensive. He stared at Patriarch Dark Heaven's Celestial Venerate Spirit Body and could sense the difference between the two.
His Heavenly Venerate Spirit Body was as resplendent as crystal and extremely pure. Meanwhile, the Mysterious Sky Patriarch's Heavenly Venerate Spirit Body contained the stars in the sky and emitted a strange, mysterious feeling.
"Looks like this should be the way to strengthen the Heavenly Sovereign Spiritual Physique. However, I've just reached this level, so I'm still unfamiliar with the cultivation of a Heavenly Supreme."
Mu Chen thought to himself. After all, he had always relied on himself for his cultivation. He did not have any seniors to guide him at all times. At the same time, he did not have any superpowers behind him. Naturally, he lacked some experience in this area.
However, Mu Chen vaguely comprehended something as he fought the Profound Sky Ancestor.
Therefore, his eyes flickered, and he shot forward like a shooting star toward Patriarch Darkheaven.
He did not use any Divine Ability. He had relied on the power of his Heavenly Sovereign Spiritual Physique to unleash the most violent physical attacks.
That's because after stepping into the Heavenly Sovereign Realm, his physical body had been converted into pure Spiritual Energy. Thus, every single move of his would contain an indescribable power. Putting it bluntly, even a casual punch from Mu Chen wouldn't be any weaker than the Eight-Divisional Pagoda.
"Hmph, you want to fight with me with your initial Heavenly Sovereign Spiritual Physique?"
When the Profound Sky Ancestor saw Mu Chen's stance, he sneered. He thought that Mu Chen was feeling indignant about being in a disadvantageous position. However, this was also what he wanted. After all, he had the upper hand in a battle between Spiritual Physiques.
Thus, his body trembled and the surrounding stars flickered on his body as he soared into the sky, turning into a streak of light that clashed with Mu Chen once again.
Boom!
High up in the sky, two beams of flowing light kept colliding. They were entangled together, relying on the strength of their bodies to fight. Every time their fists and legs collided, even if they were only shadows, there would be an earth-shattering sound.
At this moment, thunder rumbled in the sky, causing the heavens and earth to tremble.
Countless gazes looked at the two intertwining silhouettes in shock. Due to the Spiritual Energy around Mu Chen and the Profound Sky Ancestor being too powerful, anyone beneath the Heavenly Sovereign Realm would feel a stinging pain in their eyes and the Spiritual Energy in their bodies would fluctuate.
Although they couldn't continue watching, everyone could tell that the Profound Sky Ancestor had the upper hand in this confrontation. Every single clash would cause Mu Chen to be pushed back. However, Mu Chen was extremely courageous. Even if he was in a disadvantageous position, he still unleashed a storm of attacks towards the Profound Sky Ancestor.
"Lord Datura, the Abode Ruler doesn't seem to be in a good situation." When Liu Tiandao and the rest saw this scene, they couldn't help feeling a little worried.
Exchanging a glance, Datura and Ling Xi calmly looked at each other, since they understood Mu Chen too well. The latter did not even use any of his trump cards and was only relying on his powerful Spiritual Physique to fight.
They were clear that Mu Chen possessed the Three Pures and Eight-Divisional Pagoda, two Peerless Divine Abilities. However, he did not use any of them. Evidently, he was using the Profound Sky Ancestor as a whetstone to comprehend the difference between Heavenly Sovereigns.
Boom!
Up in the heavens, the sky trembled with another ferocious clash. Mu Chen's silhouette trembled and he was blown back a few thousand feet. When he took a step back, even space had collapsed.
Although he was pushed back, a smear of light flashed across Mu Chen's eyes.
His gaze was blazing. After clashing with the Profound Sky Ancestor time and time again, he had finally sensed the difference between the Profound Sky Ancestor's Heavenly Sovereign Spiritual Physique and his.
Every time his Spiritual Energy invaded the Profound Sky Ancestor's body, the stars in the sky would revolve and dissolve the Spiritual Energy that invaded his body.
The neutralizing power of the revolving stars was obviously much more powerful than his method of forcefully enduring it.
That meant that the Profound Sky Ancestor's Heavenly Sovereign Spiritual Physique was of a higher grade than his own.
Although his Heavenly Sovereign Spiritual Body was powerful, it seemed to be separated from his body by an undetectable layer. That layer of separation caused his Heavenly Sovereign Spiritual Body to not possess such miraculous abilities.
On the other hand, the Profound Sky Ancestor had thoroughly displayed this ability, which was the reason why the Profound Sky Ancestor could gain the upper hand in their clashes.
"My flesh, bones, and even my flesh and blood are all spiritual bodies. If there's still a barrier, then it should be in the depths of my body." Mu Chen's eyes flickered as thoughts rapidly circulated in his mind.
At a certain moment, a light flashed across his mind. The comprehension that had flashed in his heart when he clashed with the Profound Sky Ancestor had also appeared.
"I know what it is!"
"It's the Spiritual Pulse!"
A sliver of understanding flashed within the depths of Mu Chen's eyes. The so-called Spiritual Pulse was something that every single person who had started cultivating would have a deep impression of. When one had just started cultivating, the higher the grade of their Spiritual Pulse, the faster their cultivation speed would be.
Mu Chen still remembered that his great enemy, Ji Xuan, possessed a Heavenly Spiritual Pulse during the Hokuang Reiwon era.
But as one's strength reached a certain level, the Spiritual Pulse gradually disappeared. Many people felt that the Spiritual Pulse was only useful in the beginning of cultivation, and the effect would diminish as time went on.
Speaking from a certain degree, there was some logic to it. It was so much so that even Mu Chen felt the same way. But in that instant earlier, he finally understood the reason.
The Spiritual Pulse in the depths of the body wasn't useless, but many people didn't have the strength to refine it. Thus, those with the strength to refine it had to meet a certain condition.
That was to step into the Heavenly Sovereign Realm and cultivate the Heavenly Sovereign Spiritual Physique.
Only by converting the physical body and spiritual body could one sense the Spiritual Pulse in the depths of the body and refine it, allowing one's Spiritual Physique to reach perfection.
Mu Chen stood in the sky with a smile on his face. When he stepped into the Heavenly Sovereign Realm and cultivated the Heavenly Sovereign Spiritual Physique, he had already vaguely felt that he was lacking something. But after fighting with an experienced Heavenly Sovereign, he finally understood what it was.
When the Profound Sky Ancestor saw Mu Chen's expression, he squinted his eyes and briefly pondered. He had seen through Mu Chen's motive and the corner of his lips twitched. He was inwardly enraged. That brat actually treated him as a sparring partner and made use of their battle to perfect his own weakness.
To think that he had previously said that Mu Chen was prideful and wouldn't admit defeat. But who could have expected that Mu Chen would purposely fight with him to grasp the path to perfection of the Heavenly Sovereign Spiritual Physique?
The Profound Sky Ancestor's face was dark as he stared at Mu Chen and gritted his teeth. "Looks like you're pretty smart to find out the flaw of your Heavenly Sovereign Spiritual Physique so quickly."
"That's right. This old man will clearly tell you that the Heavenly Venerate Spiritual Body can only be perfected by refining the Spirit Veins in one's body. Furthermore, the stronger the Spirit Veins, the more wondrous the Heavenly Venerate Spiritual Body will be after refining.
"But so what if you know it?
What's the use of sharpening your spear at the last moment?! "The Profound Sky Ancestor ridiculed.
Speaking from a certain degree, it wasn't a secret. With Mu Chen's ability, even if he didn't fight with the Profound Sky Ancestor today, Mu Chen would definitely comprehend it in the future. It's just that it would take some time.
Furthermore, knowing it was one thing, refining it was another. At the very least, he wouldn't give Mu Chen the time to refine the Spiritual Pulse.
Hearing the Profound Sky Ancestor's sneer, Mu Chen couldn't help smiling. "Since I've already achieved my objective, then I won't play with you anymore."
The ridicule on the Profound Sky Ancestor's face grew even denser. But before he could speak, he saw Mu Chen forming seals with a single hand and space fluctuated before two silhouettes, one black and one white, slowly walked out and indifferently looked at the Profound Sky Ancestor.
The two silhouettes looked exactly the same as Mu Chen and when they stood beside Mu Chen, two Heavenly Sovereign Realm Spiritual Energies swept out.
The entire heavens and earth violently trembled at this moment.
The ridiculing expression on the Profound Sky Ancestor's face froze at this moment as he looked at the two silhouettes that had the same aura as Mu Chen. Even with his experience, he still felt a storm in his heart.
