In the absence of Guan Yue, First Battle God Ao Rui naturally became the leader of the Battle Gods, and he immediately realized just how important these Abyssal Spirit Dragons were to the abyssal army upon witnessing this situation.

The Abyssal Spirit Dragons were capable of boosting the overall power of the abyssal army by over twofold, and with that in mind, Ao Rui immediately raised both hands up into the air as he donned his suit of three-word battle armor. 

"We have to take out those big lizards!" His entire body began to burn like a sun in the sky, and having fought alongside him for many years, all of the Battle Gods immediately knew to gather around and protect him.

The scorching air warped violently and rippled like water while Ao Rui's aura swelled rapidly. He was already close to the Limit Douluo level, yet even he had to accumulate power for this attack, and that was a clear indication of just how fearsome this attack was going to be.

The three Spirit Dragon Kings immediately sensed the threat up above, and they raised their heads in unison before opening their cavernous mouths.

Even though none of the Battle Gods heard any sounds, Ao Rui suddenly gave a muffled groan, and the enormous mass of fire elements that had just gathered around him immediately went into an unstable state, causing a massive explosion.

"Rumble!"

A mushroom cloud erupted in the sky, and the Battle Gods that had surrounded Ao Rui to protect him were all sent flying by this abrupt and unexpected explosion.

By accumulating so much power, Ao Rui was essentially preparing a devastating bomb, only for it to be detonated by the three Spirit Dragon Kings using their ultrasonic screech, which was imbued with their super-concentrated spiritual power.

Thus, all of the Battle Gods and backup Battle Gods were sent hurtling through the air in a sorry state, and Ao Rui himself was entirely charred black with his aura also taking a massive hit.

Meanwhile, the mountain had been completely overrun by abyssal creatures, and under the cover of the Invulnerability Mist, they began to pass over the mountain, progressing toward the third and final defensive line.

The three Abyssal Spirit Dragon Kings let loose another sharp screech, and this one was meant to disrupt all of the surveillance soul tools in this part of the battlefield.

As a result, all of the images in the main control center became warped and unrecognizable, making it impossible to see what was happening, much less conduct any analysis.

A grim look appeared on Yu Guanzhi's face as he ordered, "Deploy the Eighth Air Regiment of the Central Legion to reinforce the defensive line. Tell the Battle God Hall's forces to restrict those big lizards at all cost; we can allow them to get any closer to the edge of the battlefield."

At this point, all of the Central Legion's mecha units had already arrived on the battlefield, and they stood in the path of the abyssal creatures like a series of walls of iron and steel. They engaged the abyssal creatures in a ferocious battle as heavy artillery fire continued to rain down from all of the legions.

The three Abyssal Spirit Dragon Kings remained on the mountain summit, overseeing everything as if they were the rulers of this battlefield.

In a sense, they were already abyssal creatures of the highest caliber. Perhaps their individual combat prowess couldn't compare with the emperors and sovereigns of the top 30 abyssal levels, but with their immense spiritual power, their influence on the entire battlefield exceeded even that of those high-ranking emperors and sovereigns.

The Holy Lord was the only one occupying the first abyssal level with no brethren, and then came the Abyssal Spirit Dragon Race.

Despite the fact that they were very few in numbers, Abyssal Spirit Dragons were outstanding in both individual combat prowess and leadership abilities.

Whenever they appeared on a battlefield, the entire abyssal army would be boosted significantly.

At this point, vast expanses of Invulnerability had already appeared all over the battlefield, and the innermost defensive line had already been completely conquered and inundated by Invulnerability Mist. The abyssal creatures were unable to use human weapons, but they had no qualms in destroying those weapons.

The parts of the Blood God Array that had been set up were completely destroyed, and this abyssal army was even more fearsome than the previous one.

Furthermore, the three naval fleets had their own problems to deal with, so they were unable to contribute to this battlefield with long-range artillery fire.

Ao Rui stabilized his own bodily condition with great difficulty, and it was impossible to glean his expression as his entire face had been charred black by the explosion of the energy he had gathered himself. However, his frustration was being conveyed very strongly through the look in his eyes.

Upon joining forces, the Abyssal Spirit Dragon Kings possessed superior spiritual power to him, and in that instant, they were able to infiltrate directly into Ao Rui's mind, inflicting significant spiritual damage upon him and causing him to lose control of the fire elements around him.

If it weren't for his immense power and solid foundation, there was a chance that even his soul core could've been detonated, and that would've been truly perilous.

Instead of attempting to accumulate power again, Ao Rui thrust his right palm downward, and his sixth soul ring lit up as a meteor shower of flames took shape in the sky before falling toward all of the Spirit Dragons on the mountaintop.

All of the other Battle Gods present, including Long Tianwu, Nangong Yi, Su Mengjun, Jiang Zhanheng, Ling Chen, and Luo Yuhang had also all begun to unleash attacks.

They were all gathered around Mo Zihong, who was unleashing soundwave attacks with his Demonic Zither.

All of the backup Battle Gods had also donned their suits of battle armor and had descended toward the mountaintop to battle the Abyssal Spirit Dragons up close.

Bright blue light began to glow from the eyes of the three Spirit Dragon Kings, and a faint blue light barrier was conjured up to oppose the long-range attacks being unleashed by the Battle Gods. The combined power of the three Spirit Dragon Kings managed to keep the full-scale assault of over 10 Battle Gods at bay!

This type of barrier that was entirely formed by spiritual power was different from the power that Soul Masters normally used in battle. Whenever a soul power attack struck the spiritual power barrier, some strange things would occur.

Firstly, the Battle Gods would be struck by the feeling that they had lost control over their own long-range attack. Due to the strong disruptive effect of the spiritual power, the spiritual power that they had imbued into their soul skills would instantly be dispelled.

Without their control, there would be no way to guide the attacks. Even though the Spirit Dragon Kings couldn't immediately seize control over the attacks and use them against their opponents, it was well within their ability to make the attacks disperse in all directions.

Thus, the bombardment unleashed by the Battle Gods was presenting a very spectacular sight to behold, but it wasn't actually accomplishing anything.

Long Tianwu turned to Ao Rui, and said, "This isn't going to work, Boss. Our long-range attacks can't pierce through their spiritual power barrier, so we'll have to engage them in melee combat. You cover us from the rear; I'll lead everyone and charge into the barrier. The backup Battle Gods won't be able to hold their own, so they need our help."

At this point, the backup Battle Gods had already reached the mountain summit and were battling the army of abyssal creatures.

However, all of the abyssal creatures had become drastically more powerful as a result of the Invulnerability Mist, and the backup Battle Gods were quickly surrounded.

Even further away, a large number of mechas were firing explosive artillery shells to combat the Abyssal Bomber Hornets. The dense artillery fire was holding back the Abyssal Bomber Hornets, but the hornets were also preventing the mechas from reinforcing the defensive line.

The Hornet Sovereign's objective was very simple: she had to stall the reinforcements and help the abyssal army take over the second defensive line as quickly as possible.

At this point, over 20 abyssal emperors had already entered the battle.

Just as Long Tianwu was about to rush into the fray, Ao Rui grabbed onto his arm to stop him, and said, "We can't rush into battle blindly. If we get entangled in the battlefield, then that would have a detrimental overall effect. There's no way that their spiritual power can recover as quickly as our soul power; let's pile on the pressure and see just how long they can disrupt us for."

"Alright!" The 18 Battle Gods immediately increased the intensity of their attacks upon hearing this, and all types of soul skills rained down from the heavens in a frenzy.

As it turned out, Ao Rui was correct in his judgment.

Under normal circumstances, spiritual power was definitely expended at a faster rate than soul power, especially when it came to maintaining large-scale abilities like this spiritual power barrier. Furthermore, recovery for spiritual power was also slower than it was for other forms of energy.

Thus, only several minutes later, the three Abyssal Spirit Dragon Kings were finally struggling to withstand the assault, and some of the Battle Gods' attacks were beginning to land on the mountaintop to kill abyssal creatures, thereby alleviating some pressure for the backup Battle Gods.

"Just one more push!" Ao Rui yelled as he waved his right hand through the air, and nine giant fireballs shot forth one after another crashing directly toward the three Spirit Dragon Kings.
