Two dazzling streaks of light flew across the horizon like meteorites, causing space to collapse in their path and the fluctuation caused the entire heavens and earth to tremble.

The two streaks did not take any additional means. They had just clashed together in the most brutal way possible.

Boundless spiritual light wreaked havoc across the sky, causing clouds to be wiped in a myriad mile radius.

Both sides were fighting in the sky, but the ripple from their clash caused the earth to tremble and crack...

This scene made many people feel numb in their scalps. The shock wave wasn’t something that they could bear.

Under countless shocked gazes, dazzling light burst out from the sky and the two streaks of light instantly shot back with space collapsing behind them.

Mu Chen retreated a few thousand feet and his body trembled, then turned into Spiritual Energy. It was akin ripples on a dazzling stone that dissolved the terrifying power.

On the other hand, the Profound Sky Ancestor retreated roughly a thousand feet back, but his body was unlike Mu Chen’s. The stars on his body flickered, absorbing and dissolving the energy in his body.

In this confrontation, the veteran Heavenly Sovereign, the Profound Sky Ancestor, had held the upper hand.

But even so, the Profound Sky Ancestor’s face turned grave. Through the numerous clashes, he had sensed that although Mu Chen had just formed his Heavenly Sovereign Spiritual Physique, it was unexpectedly sturdy. Evidently, the latter had a solid foundation in the past, and did not rely on a mere opportunity to soar into the sky.

When the Profound Sky Ancestor’s face turned grave, Mu Chen fell into pondering and looked at the former’s Heavenly Sovereign Spiritual Physique. He could sense the difference between his and the Profound Sky Ancestor.

His Heavenly Sovereign Spiritual Physique was pure like crystal, but the Profound Sky Ancestor’s body had stars in it, looking bizarre.

“Looks like it should be the strengthened Heavenly Sovereign Spiritual Physique... But I’ve just stepped into this realm, so I’m still unfamiliar with the cultivation of a Heavenly Sovereign.” Mu Chen muttered in his heart. After all, he had relied on himself in his cultivation path without someone to guide him. At the same time, he did not have a powerful backing behind him, either. Thus, he naturally lacked in terms of experience.

But when he fought with the Profound Sky Ancestor, he had gained a slight insight, as if he had touched something.

Thus, his gaze flickered and he charged forth once again. It was like a streak of light that emanated a boundless aura towards the Profound Sky Ancestor.

He did not use any Divine Abilities and relied on his Heavenly Sovereign Spiritual Physique to fight in the crudest way possible.

That’s because, after he rose to the Heavenly Sovereign Realm, his body was formed out of pure Spiritual Energy, so his every move contained boundless energy. Putting it in a nutshell, the power behind his punch wasn’t at all inferior to using the Eight-Divisional Pagoda in the past.

“Hmph, you want to fight with me with your initial phase Heavenly Sovereign Spiritual Physique?” The Profound Sky Ancestor snorted, seeing Mu Chen’s momentum. He thought that Mu Chen was feeling reluctant to be on the disadvantageous side from the previous confrontation, and this method of fighting was just as he wanted. After all, he was holding the upper hand in the fight between Heavenly Sovereign Spiritual Physiques.

Thus, his body trembled and the stars flickered before he soared into the sky and turned into a streak of light, then he clashed together with Mu Chen.

The two streaks constantly clashed in the sky, relying on their physiques. Every single clash would be accompanied by afterimages and an earth-shattering commotion as the sky incessantly rumbled.

Countless gazes looked at their confrontation in shock. Due to the light emanated by the two of them being too powerful, everyone beneath the Earth Sovereign Realm felt a piercing pain in their eyes when they looked at it, and even the Spiritual Energy in their bodies fluctuated.

Although they’re unable to continue watching, everyone could tell that the Profound Sky Ancestor was holding the upper hand, and every single clash would cause Mu Chen to be blown back. However, he maintained his unyielding spirit, and even if he was in a disadvantageous position, he still launched violent attacks towards the Profound Sky Ancestor.

“Lord Mandala, the Abode Ruler’s situation doesn’t seem right.” Liu Tiandao and the rest couldn’t help feeling anxious at this scene.

Mandala and Ling Xi exchanged a glance while remaining calm. They understood Mu Chen too well, and the latter practically did not use any moves except a frontal confrontation with his body.

They knew that Mu Chen still possessed the Three Pures and the Eight-Divisional Pagoda, the two Peerless Divine Abilities. But right now, he did not even use them, so he’s clearly using the Profound Sky Ancestor as a grindstone to feel the difference between Heavenly Sovereigns.

Another ferocious clash took place in the sky and Mu Chen’s body trembled while he was blown a few thousand feet back. Every single time he took a step back, he would cause the space beneath his feet to collapse.

Although he was being pushed back, there was a flicker of light in his eyes.

His gaze was blazing. He could gradually sense the difference between their Heavenly Sovereign Spiritual Physiques.

Every single time he clashed with the Profound Sky Ancestor, he could sense that the stars on the latter’s body would revolve and dissolve the Spiritual Energy that had invaded his body.

This resolving power was on another level compared to him bearing it forcefully.

That meant that the Profound Sky Ancestor’s Heavenly Sovereign Spiritual Physique was on a higher level.

Although his Heavenly Sovereign Spiritual Physique was his body, he felt that there’s a barrier in it, and he wasn’t able to possess that ability because of this barrier.

On the other hand, the Profound Sky Ancestor had exhibited this higher level to the limit, and this was also the reason why he could hold the upper hand in their confrontation.

“My blood, flesh, and bones have been fused with my body, but there’s still a barrier... It must be on a deeper level...” Mu Chen’s gaze flickered as a thought swiftly circulated in his heart.

Suddenly, a light streaked across his mind and the comprehension that he had from clashing with the Profound Sky Ancestor appeared in his heart.

“Now I know! The Spiritual Pulse!” Mu Chen’s gaze flashed with understanding. The so-called “Spiritual Pulse” was a deep impression in everyone when they had just cultivated. When they started to cultivate, those with higher Spiritual Pulses would mean that their cultivation speed would be faster.

He still remembered that his greatest opponent when he was in the Northern Heavens Spiritual Academy, Ji Xuan, possessed a Heaven-Level Spiritual Pulse.

But as his strength grew, the Spiritual Pulse logic gradually faded, and everyone only thought that Spiritual Pulses were only useful when they started their cultivation, and the usage of it would diminish progressively until it disappeared.

Strictly speaking, there’s this logic. It was so much so that Mu Chen even felt that way until now.

The Spiritual Pulse in one’s body isn’t useless, it’s just that many people didn’t have the strength to refine it, and it required a condition to accomplish it.

That was to step into the Heavenly Sovereign Realm and form the Heavenly Sovereign Spiritual Physique.

Only when your body was converted, could you sense the Spiritual Pulse hidden deep in your body to refine it and reach perfection.

A smile appeared on Mu Chen’s lips. He had already sensed that he lacked something when he stepped into the Heavenly Sovereign Realm. But after fighting with a veteran, he had finally figured it out.

When the Profound Sky Ancestor saw Mu Chen’s expression, his eyes squinted and he had seen through Mu Chen’s motive. Instantly, his lips couldn’t help twitched in anger. This brat had treated him as a sparring partner for him to fill up his flaw.

And just a while ago, he thought that Mu Chen wasn’t willing to admit defeat due to his pride, but it turned out that the latter was just trying to search for the way to perfect his Heavenly Sovereign Spiritual Physique by fighting on purpose.

The Profound Sky Ancestor’s face was grim as he stared at Mu Chen and gritted his teeth. “Looks like you’re pretty smart to find out what you’re lacking.

“That’s right. I’ll tell you right now that only after refining your Spiritual Pulse can you perfect your Heavenly Sovereign Spiritual Physique. Furthermore, the more powerful your Spiritual Pulse, the more mysterious your Heavenly Sovereign Spiritual Physique will become.

“But so what if you know about it? Sharpening your spear in battle, what’s the use of it?!” The Profound Sky Ancestor ridiculed.

From a certain degree, it wasn’t any secret. Even if Mu Chen did not fight him today, he could find out about it in the future, it’s just that he would spend a little more time to accomplish it.

Furthermore, he knew that trying to refine it was another matter. At least, he wouldn’t give Mu Chen the chance to do it.

Hearing the Profound Sky Ancestor’s cold laughter, Mu Chen also couldn’t help smiling. “Since my motive is already achieved, I’ll not play with you any further.”

The ridicule grew on the Profound Sky Ancestor’s face even further. Before he could even speak, he suddenly saw Mu Chen’s hand forming into seals and space fluctuated. Two silhouettes stepped out and coldly looked at the Profound Sky Ancestor.

Those two silhouettes looked the same as Mu Chen, and when they stood beside Mu Chen, two Heavenly Sovereign Realm powers also swept out, causing the heavens and earth to tremble.

The ridicule on the Profound Sky Ancestor’s face froze as he looked at the two identical Mu Chens with shock in his heart...
