With the arrival of the soul aircrafts, Zhang Huanyun immediately issued an order, upon which the Blood God Legion’s mechas escorted the infrasonic aircrafts of the Central Legion on a slow retreat. At the same time, the infrasonic aircrafts intensified their assault on the oncoming Abyssal Demonic Puppets.

It would be very difficult to kill creatures as powerful as Abyssal Demonic Puppets through infrasonic soundwaves along, but the soundwaves would at least be constantly debilitating them.

With the experience that had been gained through the previous battle, the soul aircrafts of the Western Legion and Northwestern Legion had adopted a very good strategy, where they split up and fought individually rather than in groups, doing their best to distance themselves from one another so they could make better use of their speed to pester the enemy. At the same time, they were doing everything in their power to avoid direct clashes in case they were affected by the Abyssal Spirit Dragons.

The five Abyssal Spirit Dragon had already released Light of Debilitation earlier, and they had been battling for quite some time, so they were already considerably taxed.

Furthermore, Abyssal Demonic Puppets ranked only slightly below them in the abyssal plane, and they didn’t dare to devour abyssal creatures of such a high caliber. As for low-grade abyssal creatures like Abyssal Bomber Hornets, they were unable to approach the Abyssal Spirit Dragons due to the infrasonic soundwaves, so the Spirit Dragons were severely limited.

However, it was under these circumstances that the Abyssal Demonic Puppets displayed their tremendous combat prowess.

Not only were they extremely fast, they were also exceptionally agile, and they quickly separated in mid-air before unleashing attacks on the soul aircrafts.

Even the slightest contact with the corrosive green light they were releasing would result in erosion of a soul aircrafts protective barrier, forcing them to abandon the barrier.

Furthermore, any aircrafts that were struck by this light would instantly be eroded and explode.

Even so, due to the fact that the soul aircrafts were employing guerilla warfare tactics, the casualties were limited to a manageable extent, and the Abyssal Demonic Puppets were left feeling quite frustrated.

The infrasonic soundwaves were constantly negatively affecting them, and the effects were particularly pronounced for those that had been blasted by the heavy ion laser cannons earlier.

Each Abyssal Demonic Puppet did indeed have two lives, but they only had one body, and even though they could survive a lethal attack, it took some time to recover from the residual damage, but they clearly didn’t have that luxury right now.

Abyssal Demonic Puppets possessed incredible defensive prowess, but heavy ion laser cannons were the perfect counter to them as these weapons destroyed the target from the inside.

In addition to that, there were the infrasonic aircrafts, and the mighty army of Abyssal Demonic Puppets was unable to perform to even half of its usual maximal capacity.

“Weapons fully recharged!”

Finally, the heavy ion laser cannons were recharged.

Zhang Huanyun immediately issued the order to fire upon hearing this, and the cannons locked onto one Abyssal Demonic Puppet after another once again, particularly those that had already lost a head.

In the next instant, invisible laser beam shot forth, and one Abyssal Demonic Puppet after another exploded before falling out of the sky.

Zhang Huanyun was struck by an urge to shed tears upon seeing this.

Over a third of the Abyssal Demonic Puppets had perished, disintegrating into extremely dense clouds of grey energy that surged toward the abyssal passageway, and one could see just how powerful they were from observing the density of their abyssal energy.

Of the roughly two-thirds that had survived, a good portion of them only had one head left each.

The Spirit Sovereign immediately let loose a sharp screech upon seeing this. These losses were too heavy, and he was finally issuing the order to retreat.

Only then did the Abyssal Demonic Puppets swivel around and fly back toward the abyssal passageway. The attacks from the soul aircrafts were completely unable to harm their bodies and could only raise some sparks against their skin, thereby further highlighting just how important the heavy ion laser cannons were.

The combination of the soul aircrafts, heavy ion laser cannons, and infrasonic aircrafts was exerting significant pressure on the abyssal creatures.

Normal abyssal creatures were severely affected by the infrasonic soundwaves, while more powerful abyssal creatures were threatened by the heavy ion laser cannons.

As the commander on this section of the battlefield, Zhang Huanyun chose not to initiate an attack on the abyssal passageway. Instead, he led his troops to skirt around the abyssal passageway, clearing away the enemies on the sides. Not only were they inflicting heavy losses on enemy troops, most importantly, they were buying time for the second defensive line.

The Hornet Sovereign was forced to flee in a panic. Her army of Abyssal Bomber Hornets were extremely susceptible to the infrasonic soundwaves. Upon being affected, an Abyssal Bomber Hornet would immediately explode, causing chain reactions that set off more explosions among its brethren. No matter how quickly they were being resurrected in the abyssal plane, it couldn’t match the rate at which they were perishing. Thus, control over the airspace had been seized by the human army.

Even the mighty Abyssal Demonic Puppets were unable to turn the tables, and the other abyssal creatures were unable to do anything, either.

Human weaponry had finally begun to play an important role on this battlefield.

The Spirit Sovereign’s eyes narrowed slightly as he appraised the battlefield around him. The human Limit Douluos in their suits of four-word battle armor was severely restricting the abyssal army, and Gu Yuena’s Divine Origin realm spiritual power was also affecting him.

He still had many trump cards that were yet to be unveiled, but he didn’t want to reveal them too early.

As he resisted the bombardment of Gu Yuena’s elemental attacks, he cast a cold gaze toward the human air units in the distant sky.

Zhang Huanyun was being very careful to only travel along the outskirts of the battlefield, and at this point, the abyssal creatures that had rushed onto the mountain summits had all been forced back.

Aside from the Abyssal Spirit Dragons that were able to conceal themselves and escape very quickly, all of the other abyssal creatures were struggling to deal with this lethal combination.

Even with the tremendous defensive prowess that Guardian Longhorned Beetles possessed, they would still explode and perish in the face of several dozens of heavy ion laser cannon attacks.

On the ground, the Tang Sect’s mecha squadron was saving the day, while the air units were dominating the airspace. All of a sudden, the human army had gained an advantage.

The Spirit Sovereign was struck by the feeling that humans truly had become different during these past 6,000 years.

6,000 years ago, humans definitely weren’t this powerful, regardless of whether it was in terms of soul weapons or the power of individual Soul Masters.

Back then, battle armor was still in a development stage, and there was no four-word battle armor yet. Under the enhancements of these suits of four-word battle armor, these human Limit Douluos were already able to match the power of abyssal sovereigns.

As such, when faced with the powerful beings of the Tang Sect, Shrek Academy, the Spirit Pagoda, the Battle God Hall, and some other obscure yet powerful clans, the powerful beings of the abyssal army weren’t able to gain the upper hand, and that was the main issue.

In reality, there weren’t that many suits of four-word battle armor even until very recently. However, Tang Wulin’s emergence drastically lowered the difficulty of four-word battle armor crafting, and his heavenly refinement drew upon the power of elemental tribulations, which was the power of the plane to begin with. Thus, the suits of four-word battle armor that he crafted were of an extremely high quality.

At this moment, the Limit Douluos on the battlefield were exerting sufficient pressure on the abyssal emperors and sovereigns to prevent them from having a larger impact on the entire battlefield.

Now that the situation on the outskirts of the battlefield had been stabilized, the Limit Douluos were able to focus more on the battles at hand.

Right at this moment, a violent explosion suddenly erupted in the distance, and this explosion took place, everyone on the battlefield, regardless of whether they were humans or abyssal creatures, were struck by the feeling that heaven and earth had been turned on their heads.
