I don't know how long it took, but the thunderous roar broke everyone's peace, and when they opened their eyes, they could see that the surface of the shield was already in pieces, and it seemed that it would only take one more time to completely disintegrate.

On top of the shield, all the black lifeforms let out a miserable roar, tearing at the shield with their knife-sharp claws, and the meteorites that slashed through them were also helping to inflict the abuse.

In just ten minutes, the protective shield has been impacted countless times, and from a distance, the protective shield still stands to protect the empire below, but in fact, the surface of the protective shield is full of holes, and the faint light also means that the protective shield can not last long.

A pair of huge purple eyes were condensed from the surging magical energy on his body, blooming with powerful energy fluctuations.

"It's time, release the Yin and Yang Elemental Array for me!" Hayden let out a loud roar, and the demonic energy in Dil's body, which had injected him with energy, was instantly emptied, and in the center of the circle, Hayden was completely engulfed by the rich demonic energy.

The five vice-principals were ordered to unleash their five elements magic at the same time.

Although most of the students present were junior students, and the strongest energy was only at the level of the Battle King level, the energy gathered by thousands of students was definitely huge.

The elemental array suddenly lit up, and strange lines lit up one after another, and the condensed elemental power of thousands of demon warrior students quickly gathered in the center of the circle, and the energy fluctuations in the middle were rapidly increasing, just in the blink of an eye, the energy superimposed by the elements had reached the ultimate magic skill, and it was only one step away from the forbidden spell.

Hayden's eyes were completely covered in purple, the same as his body, which seemed to be completely consumed by demonic energy.

A ray of energy that could fully reach the god of war level spread around the elemental array, and as a purple light as thick as three people could surround it, it burst out from that eye, and the seven elemental imprints in the circle also rushed out at the same time, and the seven rays of light also rushed out together, spinning and converging like a storm tornado in mid-air, and finally turned into a huge dragon head, coiling its body composed of energy and soaring straight into the sky.

At the same time, the same mark appeared in the center of the Elemental Great Array under everyone's feet. The magic power that is so strong that it spreads wildly, and the entire playground and even the entire academy are densely filled with the aura of the elements.

Forbidden spell, the magic power of thousands of demon warriors converged through the magic circle, releasing a forbidden spell that only the top god of war level demon warriors can release, one move is enough to destroy a large city in an instant. Moreover, this is not a single element forbidden spell, the seven-element fusion forbidden spell is far stronger than the ordinary forbidden spell.

This is the fourth wave of offensive from the dimensional rift. Above the air, several giant alien creatures attacked with tens of thousands of alien creatures behind them and countless high-altitude meteorites, under the almost fatal impact, finally at this moment, the purple shield sprinkled countless fragments like broken glass, but in the end, the shield detonated or brought a huge explosion and blasted away most of the intruders.

However, these invaders seem endless, as if no matter how many they are defeated, they will still resurrect and continue to emerge from the rifts in the plane.

After a while, the fifth wave of the offensive came, led by several giant alien creatures, this wave was twice as large as before, both in terms of number and energy level.

As the general protective shield was breached, the floating continent, the prosperous country full of elemental energy, and the grand canyon with mountains and mountains appeared in front of these invaders one by one.

Seeing this, their faces showed greedy expressions, and the locust-like alien creatures obscured the already dim sky into a real night, and as the meteors streaked by, these alien creatures launched an all-out attack.

Among them, there are tens of thousands of black lifeforms and meteorites swooping down in the direction of the Holy City.

"Stop them! Defend our homeland! Hayden let out a hysterical roar, and his power was unleashed to the limit. And Dill was also shaken all over his body, and his spirit was also a little trance.

"Yin Yang Dragon Magic Technique!"

When the intense purple light met the first alien creature in the sky, the counterattack of the teachers and students belonging to the Heavenly Demon Royal Academy began.

The forbidden spell-level magic power was released in an instant, like fireworks blooming in the sky, and the dragon that gathered opened its hideous mouth and devoured most of the alien creatures in the sky above the holy city in one gulp, and then the elemental magic power was released in a ball of light that kept flickering between light and darkness, and the illusory demonic beast's head also exploded, spreading the elemental power wildly at a height of 100 meters.

The light fell, and all the foreign forces within a radius of hundreds of miles under the power of the Elemental Great Array were swept away, and even the weak people within a range of thousands of miles could not escape the fate of obliteration.

The power of the forbidden spell can make the people on the ground tremble, even at high altitude. It was also at this moment that Dill finally understood why the Floating Island only accepted the strong, the greater the ability, the greater the responsibility, just such an impact, if it was an ordinary person who did not cultivate the power of the demonic source, I am afraid that he would also pass out directly.

The battle of the fourth wave of the Dimensional Calamity is over, and it has only been more than three hours since the Dimensional Rift has officially opened, and this time is only the beginning of the Calamity.

There is a short break between a wave of invaders being dealt with, which does not mean that the fighting stops, but that there are fewer meteorite falls, the number and size of alien creatures are smaller, and the frequency of ground tremors, tsunamis, and volcanic eruptions is a little less.

The rain was getting heavier.

However, the battle in the sky continues, the protective shield covering the entire floating empire is shattered, and the alien creatures seem to see the hope of victory, and the attack becomes more and more frenzied.

However, what they defeated was only a protective shield composed of magic energy, and the defense line on the Demon Source Plane and the Floating Island was not broken, and in the Floating Empire, the city-building army resisted with a loud shout in the distance, and the Demon Warriors who had long been ready to attack used various elemental magic, and the Source Warriors were not to be outdone and rushed over on their mounts and brandishing weapons. One after another brilliant magic skills were released, one after another the metallic luster flickered, for a while, the elemental energy, magic source power, magic energy and chaotic qi in the sky were intertwined with each other, in the shouts of bombardment and fighting, the first batch of alien creatures that exceeded the height of the original protective shield finally failed to avoid turning into chaotic qi and returning to the cracks, however, this is not all, there are still some alien creatures whose corpses have not yet dissipated, they were taken away by the source warriors with sacks, and some were directly devoured by the powerful source warriors who cultivated magic energy.

"Headmaster!"
