"Testing," Tak Jiwoo says.
"I don't have much time, but I want to share something with you. I've created my greatest and worst invention yet. It's a torture chamber, and I'm truly sorry for its creation. But if I hadn't done it, some other scientist would have, so I feel like I had no choice."
Tak Jiwoo let out a sigh, realizing his excuse sounds weak.
"Anyway, this torture chamber is as perfect as it can be. It's filled with modified nitrogen, which has the same effect as pure nitrogen. But the time inside the chamber is different than in the real world. To be precise, every millisecond in the real world is equivalent to 100 years inside the chamber. So, it's the perfect torture chamber."
"But the thing is, I know the 8th Mafia clan won't let me go. So, I decided to betray them before they betray me! I was going to use this chamber for my own benefit, but I made sure to specify cryvallium for the torture chamber as it has a hidden trait. Cryvallium was used to cultivate and improve strength during martial eras. And to cultivate cryvallium, one needs to be in a harsh environment with an empty mind. The torture chamber is far beyond a harsh environment, but having an empty mind while experiencing immense pain is quite contradictory. Then I realized that unconsciousness was the key. So, I kept the unconsciousness period very short to avoid suspicion. But in reality, the cultivation period is extremely effective. And because of the time difference, even though to our eyes, it may look like the person is unconscious only for a second, in reality, they have been unknowingly cultivating for long periods of time."
He smirked as he looked up at the starry sky through a small ceiling window.
"Eventually, the 8th Mafia Clan will become overambitious and try to control someone way over their depth. And that's when the torture chamber will create a monster that they can never control and who will be hungry for vengeance. I know it's a living hell, but I hope for the best for everyone. I don't expect any pity or forgiveness. I don't even forgive myself for it. But it's too late now. This is my revenge and my legacy. Good luck to whoever fulfills it."
The Professor awkwardly smiled at the camera before turning it off.
