Even for the people in the Battle God Hall, not all of them were aware of this soul fusion skill between Ao Rui and Mo Zihong, let alone everyone else from other Soul Master organizations.

This was why Chen Xinjie had already decided long ago that Ao Rui would be Guan Yue's successor as the Battle God Hall Master.

Any Soul Master organization had to be supported by sufficient power. Otherwise, they would be crushed like the Spirit Pagoda had been by Shrek Academy.

The name of their soul fusion skill was Rising Sun Heavenly Zither!

Even though no one was playing the zither, its strings were being strummed on its own, and all of a sudden, the air temperature suddenly began to rise drastically, as if the very sky had been set alight.

Everything up ahead began to warp and twist, and the turbulent energy storm was torn apart down the middle.

At the same time, a violent boom also rang out in the distance. The middle-aged man that was leading the abyssal camp had swept his right hand through the air, diverting away the oncoming Sky Crossing Divine Spear.

As his right hand was swept through the air, it instantly transformed into a sharp black claw that was rather peculiar in appearance in that it only had four fingers, each of which was tapered to a sharp point and inky-black in color.

As the claw swept through the air, it was as if it were capable of breaking through the restrictions of this entire plane, and the fact that it was able to swat away the Sky Crossing Divine Spear was a reflection of its incredible power.

However, Guan Yue had already achieved his objective.

Even though his spear had been sent flying, he had bought Ao Rui and Mo Zihong enough time to complete their soul fusion skill.

The fusion skill between them had been kept a secret all this time as there was an inherent issue with it, which was that it took a little too long to complete, unlike other soul fusion skills, which could be completed in an instant. Firstly, each of them had to unleash their martial soul true body, and only then could fusion take place. If this process were to be disrupted, then the soul fusion skill would fail.

As the Rising Sun Heavenly Zither took shape, a faint smile appeared on even Guan Yue's face.

The first string was strummed; Clearing Skies!

A resounding zither note rang out, releasing a burst of bright radiance that resembled a blade of light, and it reached the abyssal camp in the blink of an eye.

The leader of the abyssal creatures furrowed his brows slightly upon seeing this, but displayed no intention of taking evasive measures. Instead, he stepped forward and thrust his right claw forward, as if he were preparing to catch the attack with his bare hand.

"Boom!"

The blade of light exploded, and the entire sky was transformed into a sea of scorching radiance. The entire heavens was warping violently, and that was sufficient testament to just how fearsome the temperatures were.

All of the other Battle Gods had already converged around the Rising Sun Heavenly Zither, and while withstanding the attack, the leader of the abyssal camp also underwent a transformation.

His humanoid body instantly swelled to over three meters tall, and that was particularly large among abyssal creatures, but upon adopting this form, he automatically drew everyone's attention, as if he had become the centerpiece of this battle.

His head was extremely large, taking up virtually a third of his body, and skull-shaped eyes also became clearer due to the enlargement of his head.

A pair of massive wings spread open on his back, and his hands had both transformed into sharp claws.

At the same time, a dark red hue had appeared over his inky-black body, and it was clear that he had struggled to withstand that attack in his human form.

Even so, Guan Yue was stunned to see this. He was well aware of just how powerful the Rising Sun Demonic Zither was, and the fact that this abyssal creature had withstood the attack with his body alone indicated that his physical constitution was comparable to A'Ruheng's Invincible Vajra Body.

However, what was different was that the Invincible Vajra Body was very well-rounded and balanced, whereas this abyssal creature's body was extremely hard and stoic.

"All of you must die!" His voice was rather stiff, and he seemed to be far less proficient in speaking the human language than the Spirit Sovereign.

In the next instant, he flapped his wings vigorously, and his body instantly swelled to over 100 meters tall. He took a giant stride forward, and he instantly pounced toward the Battle Gods, reaching out with his massive claws as if he were preparing to tear the Rising Sun Heavenly Zither apart!

He was the master of the fourth abyssal level and the ruler of the Abyssal Demonic Puppet, the Demonic Sovereign!

His physical defensive prowess was ranked number one in the entire abyssal plane, and it could be said that he was as powerful physically as the Spirit Sovereign was spiritually.

His physical constitution was already infinitely approaching the godly level, and in the wake of the Spirit Sovereign's death, he was now the leader of the abyssal army. 

In the face of the Battle Gods, he immediately unleashed his incredible power, which was superior to that of the average quasigod, and all of the other powerful abyssal beings quickly followed along close behind him.

Thus, a full-scale battle commenced.

The Rising Sun Heavenly Zither's second string was strummed, and right when this happened, heaven and earth seemed to have been turned on its head.

Despite the Demonic Sovereign's immense power, it was still affected by this sudden change, and he was unwittingly turned around, flying away from the human camp instead of toward them.

What was even more peculiar was that he was the only one affected, while the other eight abyssal creatures continued to charge directly toward the human camp.

As it turned out, the Rising Sun Heavenly Zither was an extremely rare control system soul fusion skill!

This was the most powerful control system ability of the Battle God Hall.

The Hornet Sovereign and the Black Sovereign were charging along beside the Demonic Sovereign, and the sudden departure of the Demonic Sovereign left them completely befuddled.

Before they had a chance to react, the Battle Gods were already upon them.

Guan Yue was leading from the very front as he thrust his Sky Crossing Divine Spear forward in a plain and simple, yet extremely lethal strike.

The Black Sovereign instantly felt a chill run down her spine, and this chilling sensation had originated from the very depths of her soul.

She had already faced Guan Yue in battle earlier, and even though she had been dominated throughout that battle, this was the first time she was feeling this bone-chilling sensation.

Guan Yue's calm eyes were giving off a faint cold light.

To him, Chen Xinjie had been both a mentor and a friend, yet he had perished on this battlefield. As the current Battle God Hall Master, he had to keep his cool, but behind his calm facade, no one was more grief-stricken than he was.

He and Chen Xinjie had been colleagues for over 50 years with Chen Xinjie managing external affairs, while he attended to the internal affairs of the Battle God Hall.

It was through their seamless cooperation that the Battle God Hall had reached its current heights, and Chen Xinjie's death had shaken him to the core.

For the first time, the heart of the placid and tranquil Battle God Hall Master was filled with raging killing intent. During his previous clash with the Black Sovereign, he hadn't displayed his full power as Tang Wulin hadn't yet arrived on the battlefield. He could've chosen to kill the Black Sovereign, but the battle would've been extremely taxing to him, and if the Black Sovereign's abyssal energy were to escape, then his efforts would be wasted.

Thus, he had constantly been waiting for this opportunity. The abyssal passageway had already been sealed, so there was no way for abyssal energy to escape, and Guan Yue was finally displaying his full power in this battle to the death. This spear strike appeared to be very plain and simple, but if one were to judge that book based on its cover, then death would surely await them.

Meanwhile, the Hornet Sovereign was facing countless sword projections unleashed by Long Tianwu and Su Mengjun.

They hadn't unleashed their soul fusion skill yet, but having worked closely together for so many years, the two of them still formed a lethal combination.
