My Space-Time System

Hearing what major Reeves had said, Blake zoomed in on an elite rank knox. Holographic images began appearing on its head, hind, and heart, displaying its weakness.

'The cannons are connected to the city's database of beasts, making it easier for the users to decide how and where to attack.' Blake was astonished by this discovery.

"Your task is to kill all the beasts within your specified location. Begin!" Major Reeves announced the beginning of the exercise.

"Let's see what we have here…" Blake wasn't in a rush to fire the mana cannon, he first began analyzing the battlefield.

If there was something that he understood from all the exercises they had so far, it was the need to be efficient. Even though the mana cannon had 'unlimited' energy it didn't mean they were meant to waste it.

After using the information from the wall to identify all of the 43 beasts below, Blake activated the 2nd AOE skill of the mana cannon, meteor shower.

This caused the mana cannon to adjust the muzzle to a 45-degree angle before it began vibrating. In a matter of seconds, a large floating ball of mana began forming a few inches away from the muzzle. With his vision connected to the cannon, Blake could see a loading bar beside the ball of mana, and when it got to 100%, Blake fired the meteor shower into the air.

Just like his spells, Blake still felt a connection with the meteor shower, and once it had reached the specified altitude for its target Blake put on his serious face because this was where the real work began.

Putting the location of the beasts below into consideration, Blake controlled the mana ball to explode causing mana spears of different sizes to fall at blinding speeds.

BOOM! BOOM! BOOM!

Multiple explosions rang out and once the dust had cleared up no beasts were standing in his assigned location.

'That felt… good.' On seeing the power and effectiveness of the cannon, for a second thoughts of how to get his hands on one were popping up in his head, but they didn't last long either.

A few minutes after he was done, everyone had completed their executions, and it was time for major Reeves to grade them.

Just like professor Gibson had analyzed, the second years performed better individually. The exercise aimed at testing their mana control, and by being a year ahead of the 1st year students theirs was better by default.

Almost all the entire 2nd-year students made a perfect 2 points, while the worst of them made 1 point, bringing the overall score of 3 of the teams to 10 and the last to 8.

As for the 1st years, their overall point was quite average, but unlike the 2nd year teams none of them had gotten a perfect 10 points and that included Blake's team.

" I am so sorry for letting the team down." Tessie apologized with her face down as she felt disappointed in herself. She had managed to fire the mana cannon, but she hadn't killed all of them with a single shot, therefore making her execution inefficient.

"You don't have to be hard on yourself, it is just points, and besides you aren't familiar with the mechanism of the mana cannon like us." Blake said as he raised her head and smiled at her, causing her face to redden.

As for other 1st year teams they had done worse than Blake's team. Owen's team had gotten 8 points in total, while the other 2 teams had a total of 7 and 6 points.

"It is glad to see that you guys are at least good at something." Major Reeves turned to the 2nd year teams. He didn't have much to say because everyone's performance was not bad at all, but he had also come to the same conclusion as professor Gibson.

After the exercise, they all returned to their posts on the wall for their night shift. It didn't take long for more beasts to return to the city barrier, but luckily for Blake's team, no dangerous beast came to their section of the wall.

…

The next day after lunch, the teams returned to the wall for the 5th lesson.

When they got to the top of the wall, they saw major Reeves in his usual position, but beside him were 5 ash corps who had black and ash X-shaped straps on their torso region.

'The fuck is going on?' Everyone was confused but could only wait for major Reeves to explain.

"Today we would be looking at the 5th lesson, which is going down the wall to kill a particular beast or a group of beasts." Major Reeves announced.

"This is a work done by the special ops unit standing beside me." Major Reeves said pointing at the ash cops. "During the main event, on multiple occasions where troublesome beasts appear they are to be sent to kill them. So you don't have to worry that you will be sent out, this is to prepare you all for the worst-case scenario."

'Worst-case scenario?! He is indirectly trying to say that there is a possibility that we would be sent out!' Brian was screaming through the mind link when he analyzed what major Reeves had said.

'Don't you think you are overthinking? If something was to go wrong and all the special ops team were to die, do you think it would be better sending kids over normal ash corps?' Castiel said making Brian rethink.

'Isn't what they are doing almost the same thing as suicide?' Blake couldn't help but ask because he couldn't imagine how they could move through a horde of beasts and come back alive.

[The ash corps should have found a way to reduce the mortality rate of the special ops units, but even if they haven't, each of them is ready to sacrifice themselves for the city.] The system explained.

"Now watch the demonstration closely, because you all would be next." Major Reeves said.
