My Space-Time System

The fire salamander wyvern had a body length of 25ft and a wingspan of 30ft. Its entire body except for its wings was covered by yellow and black scales, and although its scales couldn't be damaged by spells and weapons below the epic tier and peak demigod realm respectively, they were poisonous to the touch.

The tier 1 emperor beast possessed a 5-inch long pair of underside horns, vertical pupil surrounded by thick yellow sclera that could make a nascent demigod's bone shiver. Its nostrils were like chimneys that spilled out thick black poisonous gas with each exhalation.

It was a master of fire and air elements and had the innate ability to continuously generate poison in the form of both gas and liquid.

It was so poisonous that even its aura was also poisonous, eliminating it as ever being a possible pet (ie if it could be made one). It had stopped midair to prevent killing all the trees and beasts nearby.

'Why haven't they started firing at them?' Blake couldn't help but ask. The scene reminded him of how power rangers' villains would watch them assemble their megazoids without doing anything.

[War weapons are basically useless against emperor-level beasts, meaning only cultivators on their level are able to take them down.] The system explained but quickly continued before they could interrupt him.

[Before you ask why they haven't begun attacking, it is quite simple. If they are to go out to fight, it opens them up for a surprise attack, and creates chances for them to get boxed in from all sides.]

'So they have to make sure the beasts have fully committed to the battle before they could do anything.' Blake said in realization.

[Exactly, they are the defenders. So unless they are attacked it is not wise for them to move.] The system said.

'Speaking of attacking.' Castiel pointed to the large water wings that had appeared at the back of the hippodon.

The large wings began flapping slowly, raising the hippodon that easily weighed more than a mountain into the air, but it didn't stop there.

When the tier 2 emperor beast had reached the same height as the fire salamander wyvern, a solid water construct appeared below it. Once it was standing on the water platform, the large wings made of water began disintegrating.

The hippodon simultaneously opened its 3 mouths, causing all the water molecules in the area to begin gathering at its mouth.

'Holy fuck! Is that… that what I think it is?' Blake was star-struck as the hippodon was charging the emperor level of the armored hippo's signature move, Hydro bombs!

What looked like a full minute of gathering water in the eyes of the humans, were actually seconds it took to form 3 hydro bombs, each half the size of the hippodon.

'What can be a better time to act?!' The hearts of the students were filled with dread as the hippodon launched the hydro bombs at different parts of the city's barrier.

BOOM! BOOM! BOOM!

On collision with the city barrier, both the ground and wall shook violently but many had braced for impact saving them from losing their balance.

'Fuck…' The faces of the students were full of shock when had opened their eyes and saw 3 massive holes in the lower part of the city barrier, but that wasn't the worst part.

Looking outside the city barrier, the fire salamander wyvern couldn't be seen. In its place was a gigantic darkish-orange fireball double its size.

'The fireball is bigger than itself?!' Blake's mind was blown by the scene.

[Casting the 3 hydro bombs had drained the atmosphere to the point that a spark of fire would set the air ablaze. This made it easier for the fire salamander wyvern to generate so much flames within seconds.] The system explained, but Blake currently had no use for the information because there was a bigger problem at hand.

(AN: Are fire and water a good or bad combination? Let me know what you guys think in the comments ;)

The hydro bombs had opened clear paths in the city barrier for the gigantic poisonous fireball to get into the city.

At this point, Blake was finding it difficult to decide what to do. The inactions of the powerhouses were making him slowly lose faith in them. Now that an attack was aimed at those on the wall, he was stuck between the strong urge to ditch the wall or trust them for what might be the very last time.

…

At the center of the wall, colonel Darius had easily seen the trick both emperor beasts had pulled off, but he saw it as lame.

Seeing the gigantic fireball was about to be fired, colonel Darius let out a helpless sigh before speaking. "Seems they really want to fight."

Immediately the last word was uttered, colonel Darius had disappeared from his spot and had appeared midair in front of the city barrier.

At that moment, the emperor rank wyvern had shot out the gigantic poisonous fireball, and in less than a second it had covered the enormous distance.

"Time to show them a better combination."

Fusion magic: Extinguisher!

Colonel Darius calmly snapped his finger causing the attack to fade into thin air like nothing ever happened.

'How is that even possible?!' Blake and his team couldn't believe their eyes. From their own point of view, the gigantic fireball had disappeared and appeared in front of the city barrier, but instantly it was gone.

'Did you see what happened?' Blake asked the system.

[Luckily you had seen what happened, but it was too quick for you to comprehend. So all that is needed is to slow things down.] The system said as it replayed the memory at half the original speed.

'Apart from him snapping his fingers, what is the difference?' Blake asked with a raised brow.

[Who said I was slowing it down for you?] The system snorted as it began analyzing the memory.
