My Space-Time System

Just as the group arrived at the center of the wall. The ground at the middle of the beast formation began quaking for almost a minute before 20 elite rank aardvarks and large amounts of water burst out of the ground falling trees around the area.

Unlike the previous holes that were only 20 meters wide, this was more than double the size and there was surely nothing good about it.

The humans were still wondering what the need for a bigger hole was for, but that was when a very large figure began emerging from below.

"What the fuck!" Blake and his team exclaimed in unison as they saw a 3 headed armored hippo rise from the water.

This was a hippodon, the emperor rank of an armored hippo. It stood at a staggering height of 40 meters and was 18 meters wide. They possessed 3 heads that were capable of individual thinking and were able to split from the main body to form 2 other hippodons.

The charcoal-colored armor of the hippodon covered every inch of its body except for its holes, making it immune to all weapons and spells below the epic tier and peak demigod realm respectively.

Hippodons were masters of the water and earth elements, making them walking mountains but with firepower greater than that of an angel.

"How do humans even fight something like that?" The students shuddered at the sight of something so huge and powerful enough to snuff out their puny lives with just a glance.

[If you are afraid of that thing, then you should be more afraid of colonel Darius.] The system said as they watched the Hippodon's body completely leave the water.

Colonel Darius' unimpressive physique coupled with the smile that was always on his face would make people that had no clue of who he was, mistake him for a recruit. It was only those that had seen him in action would know why he has been the city's colonel for decades now.

'That's some Jesus shit going on there.' Brian said through the mind link when he saw the massive hippodon standing on the surface of the pool with its hind legs.

"ROOOAAAAARRRR!!!!!"

The emperor beast bellowed with rage, as its powerful roar shook the earth itself, killing all beasts and uprooting all the trees nearby, and causing those far but within sight to lean outwards.

AHH!

The students screamed as the roar of the beast struck their ears like a wall of pain. They instinctively clutch their ears in pain as they wanted it to stop. Most of the students had dropped to the floor as they tried to coil into themselves in an attempt to mitigate the onslaught of sound.

Then suddenly it stopped, there was finally dead silence.

It took some time before Blake could regain his balance, but he felt his ears were wet.

"Fuck me! I didn't know it would be that powerful." Still being assaulted by a massive migraine, Blake looked at his hands and there was blood.

The distance between the emperor beast and the wall was too huge, so none of the students had expected it to get that far.

'What the fuck is the city barrier for if it can't protect us from sound waves!' Brian cursed through the mind link.

[The city barrier is the reason that your head hadn't exploded. That wasn't any normal roar, the hippodon had used water particles in the air to make it travel father without losing intensity.] The system explained shocking the trio.

Sound can't travel in a vacuum, it needs a medium like air to be propagated. The distance the sound waves would travel was dependent on the medium of propagation. The denser the medium was, the more frequent and farther the sound waves would travel.

So since water is 830 times denser than air, the soundwaves were amplified. The clash between the amplified soundwaves and the city barrier had greatly reduced its intensity, but the vibrations produced were enough to hurt the unprepared students.

(AN: Hope the science doesn't bore you guys. Just trying to make sure everyone is carried along.)

What shocked the trio was the hiippodon's ability to control the water element to such a degree and large scale without even the system noticing in time to warn them. Elemental manipulations at such a level were hard for even demigods, but the emperor beast had done it so easily that it took less energy than breathing.

They had no clue that such an amplification would have killed thousands of beasts, but the hippodon had made sure to have controlled the part of the amplification.

'They knew about this?' Blake couldn't help but ask when he looked at the team of ash corps. They hadn't moved from their position and the looks of it, they were unharmed.

When all of the group were finally up, that was when they saw that their worries were not yet over.

A giant burning object was launched out of the original forest. It reached its highest point and began descending. It was raging towards the city.

The burning object that left a thick black trail of smoke continued raging towards the city, but when it was the same distance away from the city as the hippodon, it came to a sudden halt in midair.

BOOM!

The sudden stop in motion created an explosion that covered the area in thick black smoke. After a few seconds, an emperor rank fire salamander wyvern stepped out of the thick black smoke and scanned the soon-to-be battlefield.

'Is it walking on air?' Brian couldn't help but ask when he saw the fire salamander walk on thin air as if it was a hard construct.

'Seriously, is that your greatest concern right now?!' Blake and Castiel asked with raised brows.
