Wallace no longer needed his Mana Artifact to cast this spell.

Thanks to his Synthetic Mana Core, his body has basically become a medium to cast spells.

This is similar to everyone who had decided to consume the Seventh Generation Mana Artifact Liquid that is made from the life of other Mana Practitioners.

As soon as activated the Mana Spell, it caught the activation of the three Terubs who are faithfully guarding him…

Crack! Crack! Crack!

The prison that was meant to trap him started collapsing. It seems that the intensity of a magician's spell is something that the empire has miscalculated…

"What are you doing?"

The Terubs arrived while he was trying to destroy the wall…

One of them asked in a cold voice as he clenched his fist. It seems that he's ready to fight against Wallace if he decided to continue.

The young man ignored him for a moment and looked at the cracks on the wall.

'I can collapse it but it takes quite some time, huh…' Wallace thought as he quickly made his calculations. Perhaps, he would need about 40 seconds to destroy the walls of the room.

He can also try using his Void Phase but he had a feeling that it would be better to not show it to them.

Right now, the Terubs are only thinking that his Void Phase was some kind of fast movement instead of using the void to travel…

If he showed that he could move outside the room without touching the walls, then they would be able to understand the principle of his ability and he somehow didn't like that.

He felt that he should be the one learning their limitations and not them studying his powers.

"Well… You're not giving me food so I'm planning to get one myself."

Wallace said as he stopped his Traceless Oscillation for now.

He then saw that the walls started repairing themselves after he stopped his spell. It was quite an interesting site and it was probably related to nanotechnology.

He can't be too sure since Avalon's terminal is deactivated.

"Don't do something unnecessary. We are still analyzing your body Your food will arrive in an hour."

"Alright, thank you! But did you say you are analyzing my body now?" Wallace asked as he realized that they are probably using some kind of x-ray.

"Yes… Your secret will be revealed in a few hours so don't do something stupid."

The Terub was surprisingly talkative after all this time. He was even informed about what they are doing now.

'Interesting… Are they trying to see my reactions? Perhaps they are waiting for me to try and do something about their x-ray? Wait--Do they want me to release another mana spell? Hmmm…'

Wallace was lost in his thought as he tries to understand what these aliens are planning now.

When he was told not to do something, it feels like he was actually being challenged to try and do something within the room.

It feels like whatever he does, they are planning to watch and study it with their technology…

Now, the question is that would he try to do something or just silently wait here?

'I can't detect any kind of device that is watching me. They have hidden it so well, huh… What kind of technology is this… Oh! It's the Yorians!'

Wallace suddenly guessed how they are observing his movement without using their technology.

Since Avalon is not working, it means that any other technology is probably not functioning within the room as well.

With this in mind, Wallace could guess that it was done by the Aquatic Race. As far as he knows, they are some kind of experts in Mystical Abilities…

'Well… Let me use my Divine Sense again to confirm…' Wallace thought for a moment.

Right now, the Celestial is most likely still battling somewhere far away against the most powerful being of the Empire's Fleet.

He's unsure how long their battle would last but he doesn't have the time to wait for them. Their battle could last for a week or even a month.

With the amount of energy that the Celestial has, he wouldn't be surprised if that truly happened.

'Alright. I should just focus on making a plan. At the very least, I only now have to worry about these Terubs…' Wallace then continued using his Divine Sense to ensure that he had found completely understand the blueprint of the Flagship that he made in his head.

A few days had passed just like that and he was fed with a familiar nutrients bar from time to time. Though it wouldn't matter if he doesn't eat for a long time due to his Astral Core, he still decided to eat them after confirming that they aren't harmful…

After he had confirmed that he has nothing more to learn about the Imperial Flagship. He decided to move out…

His first target is the Furnace that is capable of converting the Memory Crystal into some kind of magical fluid to help the imperial soldiers.

This is time, as he walked and touched the wall with his hands, the Terubs didn't immediately act.

They have seen him doing this from time to time so already.

However, this time is different. He's planning to seriously create chaos within the Flagship now! Especially right now since he just found out that the other Invader Spaceships alongside the Flagship had decided to move out!

'One more time… This time… I'll end this quickly… Traceless Oscillation!'

As soon as he activated the mana spell, a powerful vibration occurred as the wall was suddenly cracked into pieces!

Since he has been waiting for this, he had increased the intensity of his Mana Spell. It only took him about four seconds to complete the task!

Whoosh!

This time, he finally used his Void Phase…

"Intruder Alert! Intruder Alert! The Prisoner has escaped! The Prisoner has escaped!"

Wallace heard the spaceship's intercom as he continued moving…

He decided to jump or use his void phases about three times before he appeared near the Furnace…

It is guarded by the Imperial Soldiers and they were all surprised by his sudden appearance…

"It's the intruder!"

"Stop him!"

"You're not escaping!"

They all pounced at him as soon as they realized his identity…

However, it was too late for them since he has been prepared all this time…

'Mana Bomb!'
