Two days later.
"So let's wrap this up~! It's a hard to learn skill but useful in many way, so I'm letting you learn it by yourself."
After Otuko was done teaching Saber about a new skill, she stood up from the ground, clasping her hands and refocused around their surroundings.
Saber remained quiet for a couple of minutes, then looked at her with confusion.
"That's it?"
He wanted to ask her about more details about the new skill she taught him, but Otuko brushed him off, stretched her arms up and yawned. She ignored all his questions and fought the skeletons that appeared to attack to them.
Seeing that Otuko had no intention of answering, he stopped his inquiry and sighed.
"At the very least, I managed to learn on something new." He thought quietly and tidied his clothes.
After he and Otuko had some intercourse that lasted for about a whole day around two days ago, Saber found one of his clothes missing. He was confused at first, but later brushed it off considering that he had more clothes hidden on his pocket ring.
Weirdly enough, after their intense scene, Saber felt uncomfortable the following day. It was as if someone or something was watching him from above. What was it? He didn't know. He had a hard time focusing on his training because of it.
"So... How do we defeat the Boss again?"
Saber snapped back from his deep thoughts to reality.
He turned his attention to her and stood up. "That's easy," he said, his face showing a proud toothy grin.
Otuko looked at him all confused by the expression he was making. And then, she suddenly had a bad feeling.
"I'ma blow this place up!" (Saber)
"...Wait, what?" (Otuko)
Out of the sudden, Saber raised both his hands up in the air.
Otuko's eyes widened in surprise upon feeling that all the air around them gather up above Saber's hands.
A huge white light was emitted that brightened up the whole cave, lightning sparks that zaps the rocks and enemies around them.
"Do you remember why I asked you if you are willing to die with me...?"
As soon as she realized what was happening, she quickly entered the space that was only available for his Boss Pet to enter without any hesitation.
"That's your answer, huh..." Saber mumbled to himself thoughtfully.
The huge light above his hands slowly began to get smaller, compressing it into a small ball of light that was hardly the size of his palm.
And then,
He grabbed it with both hands.
"Haaaaa....!!"
Rays of light began to escape from the gap of his fingers as he chanted:

Plasma.
This was one of the topics I was struggling to comprehend.
Back when I got transmigrated in this world as Saber, it was something that I've tried to acquire through studies with the help of Lightning Magic.
Back then, although I was able to at least learn some of it, I came to an understanding that I wouldn't be able to use it unless I have enough mana to properly supply the explosive power.
Normal plasma is great and easy to create, but a plasma that explode?
Since plasma is much more like a gas - the mutual repulsion of the naked nuclei keeps it suspended. It's not explosive unless under pressure, just like air.
However, this isn't the same world I was living in.
Some of the concept of logic here works differently from Earth.
And one of them is "mana".
By controlling the direction of the wind or creating it, gathering it into one spot and injecting some lightning.
It forms a plasma.
Not just any plasma, but a very deadly one.
Originally, plasma can be normally made by condensing the wind in one spot according to science.
And according to science studies, as the gas atoms gain energy, their electrons become more energetic and can break free from their orbits around the nucleus, resulting in ionization. This process is often used in laboratory settings and can be seen in stars like the Sun.
But since I can use magic, I can control the amount of chemicals I can use in order create something.
By compressing those air and adding some particles of lightning (energy), then using the ions and electrons to create a huge magnetic wave, I'll be able create something that no normal technologies could create. I had only seen this in the previous Era on Earth from few thousands of years ago when I decided to escape the facility.
To make the explanation short, plasma is often formed when a gas is heated to extremely high temperatures or exposed to strong electromagnetic fields, causing the atoms to lose their electrons and become ionized.
With the help magic, I'll use the same method but add some twist at the end.
What would cause the Sun to explode?
The answer is lost of fuel.
Once the fuel is gone, the star will begin to cool. This means that the pressure pushing the outer layer away from the core loses power against the gravity pulling it in.
Thus, the star eventually collapses on itself, causing a supernova explosion.
Though considering the fact that my mana is not bigger than the sun, the explosion I could cause will be small.
But, of course, it will be one of a hell'a devastating.

...I wonder if the labyrinth would be able to reconstruct itself back together again.

Upon opening my eyes, I found myself laying flatly on a grassy field.
[Welcome back.]
The system's notification rang into my ear, causing me to turn my attention towards it.
Contrary to my expectations, the panel remained normal and showed no signs of any malfunctions. It just appeared from the side of my vision like normal. I guess even a supernova explosion can harm the system.
[As if that thing can harm me.]
A light chuckle escaped my lips as I questioned it's truthfulness in my mind, then asked teasingly, "Did I cause any problem in someway?"
[Not really.] The system responded flatly, as if unbothered by my tone. I could only scratch my nape as response.
And then,
'You son of a bitch! What the fuck was that?'
I heard Otuko's panic voice inside my head.
"Simple spell... Yeah, it was just simple spell I created." I laughed awkwardly and averted my eyes elsewhere to look around.
We had a quick conversation. It was just me trying to reassure her. However, she continued cursing at me inside my head and didn't come out, afraid that I might end up doing something like that again.
In the end, I had to cut our telepathic connection off short since her scolding was starting to get annoying.
She had much to say, but I don't care about it.
And so, I returned my attention back to the blue panel floating beside me.
"System, can you show me my reward now?"
I waited for a couple of moments before a phone fell up the sky as I caught it. Turning it on, I looked through the list of abilities available.
However—
"System...?"
Swallowing my saliva, my lips twitched slightly as I tried swiping the screen up.
[Pick your ability.]
...Is this thing broken or some sort?
I glanced at the system for an answer, but it didn't take long for the system to respond with a lazy hum.
However, she didn't even answer my question.
[𝗔𝘂𝘁𝗼]
...Pick your ability my ass, this was the only ability available!
But that wasn't what surprised me the most.
"This ability...."
- [𝗔𝘂𝘁𝗼 (???)] : Upon activation, the auto-battle feature will be activated and seals the user's free will until the enemy target has been fully neutralized. After use, the user won't be able to activate it again until the 1 month cooldown.
As I stared at the description of the ability, my expression froze up.
There was mistaking it.
This was the ability that Junior had awakened to kill the Boss during his last moments.
