The sound of the horn resounded throughout the heavens and earth. On the one hand, it was for the sake of alertness, and on the other hand, it was to inform the distant army of the demons to come to support them.
At this moment, the thirty thousand demon army and the thirty thousand human army had all come out. They all stood in line and were ready.
Everyone looked into the distance with serious expressions.
Right at this moment, a small black dot appeared in the deep sky. That small black dot landed on the ground, and it grew bigger and bigger!
When the tiny black dot landed on the ground, it was an enormous black tower that was hundreds of feet tall!
The giant pagoda fiercely fell to the ground, creating a strong wind.
As the gale whistled, the human army and the demon army gave orders to attack at the same time.
The sixty thousand troops immediately charged towards the black tower.
On the black tower, there were only a dozen or so alien realm martial artists. These alien realm martial artists were all wearing white robes, and their characteristics were very distinct.
After seeing this, Xiang Nan's heart skipped a beat.
Only ten people?
The realms of these dozen or so people weren't high, they were only at the eighth level of Good Fortune.
This was not a joke. If the Profound Sky Sect wanted to attack the Demonic Beast Continent, they would send an army to sweep it if they had enough manpower.
If they didn't have enough manpower and could only send a few people, then they would have to send at least ten Martial Saint realm experts with exceptionally high cultivation bases.
Ten Good Fortune Eighth Layer martial artists wanted to destroy the Demonic Beast Continent? It was a joke.
That was why Xiang Nan believed that the realms of these ten or so people were truly too low.
"Don't act rashly." Xiang Nan roared and enveloped the two armies with his voice. "Those ten people are late Fortune Realm martial artists. You are no match for them. Quickly retreat!" He said.
"Leave this to me."
However, what was the use of the black tower? Could it be that he wanted to construct a spatial passageway?
We must destroy the black tower as soon as possible.
Just as Xiang Nan had this idea and was about to make a move, the spire of the giant pagoda suddenly lit up with a buzzing sound.
All he saw was an overwhelming wave of gas that surged in all directions like a tidal wave hitting the coast.
The gas wave spread out at a speed of about the speed of sound. This speed was not fast for Xiang Nan, but it was already very fast for ordinary people.
Moreover, the waves are completely covered, spherically diffusing and growing larger.
Before the soldiers who bore the brunt could react, they had just touched the waves and self-destructed at the same time!
In an instant, everyone who was touched by the waves of Qi, be it humans or demons, was like this!
"What?" Xiang Nan's heart skipped a beat. He had no time to think and instinctively flew into the distance.
"Hurry up and leave! Hurry up and leave!" Xiang Nan shouted, releasing the maximum amount of Astral Qi he could release, engulfing the demonic beasts and human soldiers, fleeing into the distance.
However, his ability alone was limited. He could only drag a few hundred people, including the demonic beast's general.
Time didn't allow him to gather a disk of Astral Qi and lift everyone up. All he could do in the first instant was to throw out his Astral Qi and sweep as many people as possible to escape.
The scene in front of him reminded Xiang Nanhui of the Battle of Heavenly Star City.
However, the Qi wave was clearly different from the Qi wall created when the two Heavenly Tribulation Realm experts of Heavenly Star City clashed.
Self-detonation is horrible.
No matter who it was, as long as they came into contact with the sonic wave, they would self-destruct without stopping! This created a terrifying chain reaction.
The first person self-detonated, the second person self-detonated as well. Thousands of people self-detonated at the same time, the lethality was extremely serious.
When Heavenly Star City escaped, the Qi Wall was only capable of killing people.
But the air waves here actually caused people to self-destruct involuntarily?
Xiang Nan felt his mind buzzing. He finally realized that in terms of understanding martial arts, the martial artists of his own world and those of other worlds were no longer on the same starting line.
But the horn from before had already been blown!
The demons were already prepared to fight against Myriad Demon Island a few months in advance. A large number of troops were scattered within a 100,000 mile radius of the palace, ready to fight at any time.
After the horn blew, in a very short period of time, a 200 thousand demon army immediately gathered and flew over.
On the backs of countless flying demonic beasts stood enormous demonic soldiers. Pairs of black wings covered the sky.
An overwhelming army of demons rushed over.
"Retreat! Retreat!" As Xiang Nan flew towards the demonic beast army, he continuously waved his hand and roared.
However, in such a chaotic scene, how could he command the 200,000 demon army with a single shout?
Those demonic beast armies that were originally prepared to deal with Ten Thousand Demon Island were now being used to deal with Otherworldly martial artists.
They charged in the direction of the enemy without fear of death. No demon race would hesitate, and no demon race chose to flee.
Next, Xiang Nan saw a scene that shocked him incomparably.
When the waves of air blew over, they were the first to pervade the front row of Demonic Beast Soldiers.
At this moment, all the demon soldiers who were contaminated by the air wave immediately self-destructed!
In the first row, all the soldiers self-detonated in unison. Before the second row of soldiers could come into contact with the air waves, they were destroyed by the smoke from the first row of self-detonation.
At the same time that the second row of soldiers had just been killed, the sonic wave had already spread to the third row, and the third row had also exploded! The explosion in the third row directly killed the fourth row, almost annihilating it at the same time!
As for the air wave, it rushed to the fifth row, and the soldiers in the fifth row also self-destructed!
The details of the entire process were rather complicated, but the speed at which it occurred was extremely short!
Within five seconds, the air wave had already swallowed up 200,000 troops.
Two hundred thousand demonic beast soldiers self-destructed without warning in the air!
The sky was filled with rain of blood and broken bones!
Xiang Nan's eyes turned red.
Two hundred thousand troops!
That was a 200 thousand demon army! It was as if he had been mowed, and in just five seconds, he had been completely harvested!
And that wave of Qi was the sickle that cut grass!
Xiang Nan had never seen such an efficient method of killing people. It was simply unheard of, unseen!
Only when the two Heavenly Tribulation Realm experts fought would they be able to create such a momentum.
However, what caused this situation right now was only ten Good Fortune Eighth Layer martial artists. It was impossible for them to possess such an ability!
The gigantic black tower had already begun to move, heading towards Xiang Nan's direction.
The reason for that was because the maximum distance that the air waves could reach was not far. It was only about fifty li. Once the air waves reached the fifty li boundary, they would begin to retreat towards the black tower.
However, at the same time as the first wave retracted, the second wave also spread out from the direction of the giant tower.
The giant pagoda rumbled across the ground and rushed towards Xiang Nan at a very fast speed. This also meant that the energy waves that could envelop the giant pagoda for fifty kilometers were also being pushed forward together.
