Kai spent endless cycles of slaughter in Asura's Hell every day, improving his body and changing it little by little on a physical level with the energies of the Kings. His Energy Vortex, was also constantly expanding. It was already ten percent larger than originally and the energy density was higher.
After nearly two weeks of slaughter after slaughter, it turned out that Kai's prediction didn't come true because his Energy Center was constantly improving and constantly needed to absorb a bit more energy than before.
Now when he fought in the Asura Hell, almost every one of the cycles someone from the Kings would appear and in exchange for incredibly painful injuries Kai would sometimes manage to inflict even a few wounds on them. While they were completely non-life threatening to the Kings, that wasn't the point either. Kai was slowly absorbing their energy, growing stronger. He was sure that at one point he would definitely be able to finally kill each of them and absorb them completely.
Due to training his emotions with the Torture of the Lust Queen, he was no longer looking forward to the moment when he would completely recycle all the Kings. Kai just disciplined and planned to give it his best every time. He focused on the process rather than the end goal, he realized that it would be much better and more rewarding that way!
All this time he was not disturbed, as no one but Kai could get into the room. When the door closed, all sounds coming from the hallway were blocked by the array. This was because every warrior needed complete calmness and maximum concentration to cultivate.
When a little over two weeks had passed, Kai sat and greedily absorbed the energy from the room. At this moment, a slight change in his body was felt.
Boom! An incredible energy burst out of Kai's body, spreading throughout the room and beginning to swirl around in a vortex! Kai's clothes began to lift in the wind, and his hair fluttered in the air like crazy.
At this point, the vortex began to slowly absorb into Kai's body, taking all the energy from the room and absorbing an incredible amount of it.
After a quarter of an hour all the energy was sucked dry, Kai was absorbing it faster than he had time to replenish the array.
"Duuuum!" - There seemed to be a sound in the room.
Suddenly, Kai opened his eyes, and stood up releasing his energy from his body!
Around him energy began to appear, which in texture distorted the air, like fire, but in color it was black and yet it was not hot, it did not feel any temperature at all. All it seemed to radiate was danger and a sense of fear. It was literally overwhelming and could bring a weak master to his knees with its mere appearance....
- The middle of the Cultivator, finally! Hmm... I've manifested my attribute?! - Exclaimed Kai in surprise.
- But they usually only manifest at the peak of the Cultivator... Also, black... And that aura... What's my attribute? - Kai seemed to be puzzled himself.... He didn't really understand what attribute he had awakened.
He felt that it was definitely not something related to any of the elements. And it didn't seem to be tied to a type of weapon in any way... Looking at his energy he began to look into its Essence.
"Strange, very strange... I've never seen such writing anywhere in nature... Even complex attributes are based on the Essence of fundamental energies, this one looks unfamiliar." - Thought Kai.
Looking at his energy Kai thought that if he compared the Essence of Energy to a writing system, the writing system of his energy definitely belonged to some other language... As if his energy was written in another world... That was the best analogy he could come up with in his head.
Kai looked at his ring and slowly took out one of his daggers, trying to pour energy into it. He saw the one also start to become covered in something that looked like black fire....
"It's pretty weird, I don't understand what it is. When I try to focus on it, I only feel... Hmm, like fear on an instinctual level..." - Standing in the room thought Kai.
Stopping pouring energy into the dagger, Kai tucked it back, closed his eyes and began to focus on his Energy Center.
A dense and large swirl of energy was now circling there, it was as if it too had begun to be colored with black light. So far, there were still some colorless and transparent areas in it. But that was most likely because he was only at the middle stage and his energy wasn't that dense yet.
When he enters the peak of the Cultivator, his vortex will be so dense that it will literally start to accumulate into denser particles.
"Hmm, alright... Breaking my head over this now will be completely useless. All I can say with certainty is that my energy is slightly frightening." - Kai decided not to think too much about it.
There are countless variations of energy and their attributes in the world, essentially every master is unique. Only he could see the essence of Energy, so it was unlikely that his attribute would cause anyone to question it.
- More importantly, I finally reached the middle of the Cultivator and absorbed a lot of the Kings' energy. I can feel my body overflowing with power, and my hands are itching to fight someone, hehehe. - Kai laughed evilly.
Although he hadn't changed much in appearance, his aura and gaze seemed a little more dangerous than before.
"Well, it's time to get on with my plan. I wonder how the fat guy is doing?" - Thinking about it Kai walked to the door and pushed it open.
Stepping out into the hallway, he looked around and approached the fat man's door. But remembering that knocking was useless, he decided to go downstairs and ask Lady Shiho. With that thought, he started moving down the stairs.
- Hello ma'am!" shouted Kai. The old woman was sitting behind the counter reading something, as always.
- Oh, it's you! Your friend asks me every day when he leaves to see if you've come out and to tell him if you have, and now you've come out. Why is he so worried about you? Hasn't he seen masters leave for a month to cultivate? You've only been gone for twenty days at most. - The old woman asked calmly.
- Hehehe. Miss Shiho, has the fatty done anything wrong in that time? - Kai asked with a smile.
- No, he seems to be alive and well... - the old woman said reading.
- Thank you very much for looking after us Mrs. Shiho. Please tell Diso when he comes that I'm in the bathing room. I've been cultivating for a long time, and I need a good bath. So, I think I'll wait for him there. - Bowing said Kai, and the old woman just nodded, signaling that she would honor his request.
- Thank you again! - Smiling gratefully, Kai bowed and walked towards the baths.
During his continuous cultivation, Kai had doused himself with sweat more than a hundred times. Sometimes reacting to the pain Asura experienced in Hell, he would involuntarily bite his lip or dig his fingernails into his flesh from the violent clenching of his fists.
So right now, Kai was definitely not in a very tidy state and he didn't smell very good. He could even smell that foul odor himself. Especially before going out into the city, he wanted to finally put on his new uniform that he had been given at the Food Bureau. And he didn't want to do it on a dirty body....
