My Space-Time System

"Finally, the main event!" Major Reeves said in what seemed to be an excited tone as he saw thousands of beasts pouring out of the forest.

He knew of their presence long ago, but he had been waiting for them to finally attack the city. That was why he had 'warned' them before they went out of the city.

It was when they saw the sea of beasts was not too far from the open part of the city barrier that he now looked at the battlefield.

"Why am I not surprised?" Major Reeves said when he saw that only Blake's team were the only ones returning to the wall.

He began scanning the battlefield for the students. That was when his sight fell on Serhan's team. Just like other teams, they were surrounded by beasts, but their case was worse because they had almost entered the range of night mist.

"At this rate, he would turn out to be worse than me." Major Reeves couldn't help but feel proud of Blake when he saw Serhan's team in deep shit.

"Alright, listen up!" Major Reeves used mana manipulation to project his voice all around the battlefield.

"I gave you all a chance to save yourselves, but you refused. So I am not obligated to save any of you." Major Reeves said, causing the students to curse their bad luck, but he continued speaking.

"But since I am merciful, I have decided to save you all, but at a cost." At this point major Reeves had an evil grin on his face as he continued. "5 thousand points will be deducted from anybody that is saved. If you agree to the condition and want to be saved then shoot a spell into the air."

The students had long been surrounded by beasts, and now the second wave of beasts that contained aerial beasts and hundreds of knight rank beasts had gotten past the opening in the city barrier.

It was only a matter of seconds till the second wave got to them, giving them no time to even curse major Reeves

With their lives being worth more than 5k exchange points, the students Immediately began firing spells into the air.

'Easy as predicted.' Major Reeves gave out the signal and the supervisors who had been floating near the team all this while began acting.

"Sound the alarm, the beast tide is finally here!" Major Reeves said.

A second later, sirens began sounding all over Calton city.

The south wall began trembling as parts of the wall began opening, making space for the mana cannons.

At the foot of the southern wall, the ground began opening as hundreds of ash corps alongside adventurers and volunteers marched out of the underground tunnel before grouping up in teams of five and waiting for the next order.

Over at the top of the wall, the ground began opening as the mini magic towers were elevated to the top.

The magic towers were metal towers that were 5 meters tall and 1 meter wide. At the foot was a blue handprint that connected the user to the mini-tower, while at the top was a thick metal cone that housed a large blue orb pulsating with raw mana.

[Their response time is beyond impressive.] The system said as the group finally arrived at the top of the wall.

The empty wall had been, filled up by 5-man teams of ash corps in less than 3 minutes.

'With each group taking an interception, I wonder what our new positions will be?' Brain asked as the group moved behind Major Reeves, as they waited for their next orders.

It was after all the students had been saved and returned to the wall, that major Reeves turned to them and said. "Enjoy the show while you can, because things will only get difficult from here on."

Major Reeves gave the signal, and the opened part of the city barrier was closed. This stopped more beasts from entering or escaping, leaving more than 1500 beasts in between the wall and city barrier.

Knowing that there was no way for them, the beasts were given the order to launch an attack and deal as much damage as possible to the humans, but that was when the mini-towers began giving out a low hum as the glow of the large blue orbs began intensifying.

Raising his right hand and moving it forward, the mini-tower operators began unleashing rapid-fire concentrated energy beams at all flying beasts. Everything beast that was unlucky to get hit, exploded on contact causing a mini rain of blood and beast parts.

As for the team of adventurers and ash corps, there was no need for them to act. Once the city barrier was closed and the beasts had begun swarming towards them, multiple explosions rang out from the walls. Soon the sky was lit up by large blue mana balls, as mana spears began raining down on the beasts.

'If 5 mana cannons can deal so much damage. Then why is the beast tide a problem?' Brian couldn't help but ask through the mind link. To weapons of mass destruction like the mana cannon and mini-towers, numbers didn't matter because they would be mowed down in seconds.

[Numbers don't matter because the beasts can't get to the weapons, but once the beasts pull out their big guns it would be a different story.] The system didn't want anyone of them to undermine the strength of the beasts.

'Guys check out the beasts outside the city barrier.' Castiel said through the mind link.

'What the fuck?!' Blake and Brian mind-screamed in unison when they moved their attention to the city barrier and thousands of beasts in different formations led by king and knight rank beasts.

The only and major advantage humans had over beasts was intellectual reasoning. It had prevented the human race from becoming extinct and had created a type of balance between both races, but the beast tide was here to upset that balance.
