Dill saw Hayden staggering in front of him and was about to fall, so he immediately stepped forward to catch him. He noticed that Hayden's purple eyes were misty at this time, and his consciousness was no longer clear. At the moment when he had just activated the forbidden spell-level energy, even Diel, who was standing behind Hayden, felt that his brain was blank for a moment, and now his spirit was still a little trance, and he could also imagine what kind of mental impact Hayden had suffered as the core of the magic circle, and it might even be the damage to his soul.

"Headmaster." Dill did his best to transfer his mental power to try to help him recover.

Hayden awoke, his eyes still in a trance, and he struggled to his feet, but his staff supported the ground as if a gust of wind could knock him down, and it was clear that he could no longer fight.

"Diel, don't use your strength, I won't be able to recover for a while, you better keep your strength." Hayden let go of Diel's hand, and then he looked at the five vice principals, "Five elders, please also open the academy shield." ”

The five of them nodded, chanting a spell in their mouths, the Yin and Yang Great Array lit up again, a circle of energy extended in a certain direction, and soon, a purple pillar of light rose above the tallest main teaching building of the academy, a huge protective shield that shrouded the entire academy in the sky.

The shield looked like it could withstand for a while, but after doing this, the five vice-principals all supported their bodies with their staffs, their faces full of tiredness.

"Here we go again! Here they are again! "There was uneasiness in the crowd, and it was a new wave of offensive.

"Don't worry, the Empire's army will protect us, and the shield will resist for a while. Now, all the demon warriors are resting in place, waiting for the condensation of magic skills, and the source warriors are responsible for vigilance. Hayden ordered.

As the protective shield was broken, the offensive of the alien creatures became more rampant, and the chaotic qi that permeated the sky spread rapidly, and due to the interference of chaos, the space of the entire floating island was more distorted, and taking advantage of this opportunity, the alien creatures also opened up more spatial cracks, and they were no longer limited to the sky, even some of the powerful places on the ground that were distorted in space were also opened up cracks, and more and more alien creatures poured out of the cracks.

It seems that seeing the heroic resistance of humans after the protective shield is broken, this time the alien creatures seem to have moved their true character, and the commanders of the alien creatures, the four giant alien monsters, roared in unison, and led the army behind them to take the initiative to attack.

Giant alien creatures, lord-level existences among alien creatures, there are currently sixteen known to humans with a body size of more than thirty meters, each of which has at least the existence of the War Emperor level, and some have reached the God of War level. Not only do they possess the destructive power of the Ultimate Demon Source Technique, but the most terrifying thing is that they have the ability to resurrect infinitely like all alien creatures.

In the sky above the Holy City, almost all the Demon Source Warriors who surpassed the Battle Emperor level gathered in the sky, and a total of nine people, including Id, rushed towards these four giant alien creatures and the countless armies behind them under the leadership of the Demon Source Heavenly King Satre Key.

Of course, they are not alone, there are tens of thousands of human troops on the ground.

The resistance of the army and powerful warriors attracted firepower, plus there was also a magic energy shield over the academy, some falling meteorites were blocked, and the entire academy entered a short period of safety, and the teachers and classmates of the academy also entered a short period of rest, resting and resuming, and some chatting, the scene was quite peaceful.

Dill stood beside Hayden, the offensive in the sky was still continuing, he did not let his guard down, but set his eyes on the place where Hayden was standing just now, that is, the core of the circle, he could faintly see that the rich elemental fluctuations in it had not dissipated for a long time.

It seems that Hayden didn't use all of the magic we had gathered, but it was terrifying, and he was able to cast a forbidden spell without using it completely.

He secretly sighed in his heart, he didn't know how far the superposition of all magic power could go, but this set of formations was obviously not a simple superposition of magic power, plus magic energy, it could exert a forbidden spell, it was definitely a doubling of the increase, and it might even be a tenfold increase.

Thinking of this, he gasped.

Suddenly, he raised his head and looked at the protective cover, just above the protective cover, I don't know when a crack appeared more than ten meters long, only to hear a loud bang, a huge "ball" ejected from the crack, this "ball" is more than ten meters in diameter, affected by gravity and directly smashed on the surface of the protective cover.

With a loud bang, the shield trembled violently, and the sharp crack on the surface of the impact could be clearly seen from below. It stands to reason that it would be impossible to cause such serious damage from a position of about ten meters above, and now, it seems that after a few more blows, the protective shield will be completely shattered.

It's an alien creature! At this moment, the "ball" suddenly burst into a cloud of chaotic qi, and then the huge spherical body stretched out hundreds of arms as thick as pythons, and hundreds of fists smashed together.

There was another heavy muffled sound, and the shield trembled again, and the cobwebs above spread even bigger and deeper.

"It's a hundred-armed giant!" Someone among the students recognized the alien creature.

Hundred-armed giants, able to use the advantage of a hundred arms to hit hundreds of punches at the same time, they can't fly, they can only bounce, but they have extremely strong attack power, they are the biggest destroyers of the shield, and the shattering of the shield above the floating empire also has a lot of credit.

Judging from the fact that it shook the protective shield with one punch, the size of this hundred-armed giant was probably at the level of a beast emperor-level demonic beast.

"Maintain the shield at full strength." One of the vice-principals shouted, raising his staff aloft, and the magic spell in his mouth grew faster and faster. The other four vice-principals did not speak, but so did they.

Knock Knock Knock –

Bang –

The hundred-armed giant threw several punches in a row, and the shield trembled more violently each time, and finally in the fifth punch, the shield finally broke a gap, and then quickly collapsed.

Breaking the protective shield, the hundred-armed giant did not stop, falling directly from the sky, and the shaking hundred-arm was aimed at Hayden and the five vice principals in mid-air, and the distance of 100 meters also threatened the lives of the students.

The double loss of spirit and magic power of Hayden and the five vice principals has made it impossible for them to quickly gather their magic power, and they can only perform the most basic magic skills. This kind of energy is also the same as the magic skills released by the students who reacted immediately, under the powerful energy of facing the hundred-armed giant swooping down, hundreds of arms swung out fists at the same time, and with hundreds of air explosions that sounded at the same time, all the magic skills and even the surrounding magic elements were ruthlessly shattered.

"Protect the Circle!"
