"The biggest turning point is that the eight gates of asura method does not require any meditative forms or postures to refill the mana in the body because the gates themselves automatically and continuously absorb mana, until each gate is filled with mana.
"And lastly, when the treatment is over, the gates will work like small mana cores, so the cultivator absorbing process will become faster, and their mana capacity will be bigger.
{Important Notice: it is underlined that some of these advantages will diminish in effectiveness to the cultivator stepping into a higher realm.}
While Ainz kept explaining, they began to walk past several thick metal cells, however, for some reason, they were mostly empty, and the only thing one could see were grey-looking stains that gave off a nauseous smell.
Beside that, were many skulls with insects and mushrooms growing in and out on them, together with unrecognizable bones, that anyone wouldn't be able to tell if they were from a human or something else, in all, the feeling the place gave off was extremely eerie
As they walked past these cells, Bruce could not help but take a look at Ainz from the corners of his eyes from the front, however, when he did to his biggest surprise the kid had a normal expression, completely unfazed by any of the thing he saw, Bruce was baffled, he couldn't tell if he was pretending or was truly not afraid, if it was the latter then the kid was beginning to be scary even to him.
After some time, they could no longer see any metal cells in sight, eventually, they arrived at the end of the place, where they could see a huge metal door, with a huge chain holding the metal gates. Bruce walked forward and pulled the chain aside, before opening the metal door for them to enter.
Inside the room, Ainz could see different tools, to be precise torture tools while some were stained with grey substance, some had fresh blood on them, as if it was not quite long before the tools were used.
Meanwhile, at the center a rusty metal table could be seen, it was the only thing that wasn't stained, however, it had handcuffs on both sides, Bruce looked at Ainz and then pointed at the rusty metal table.
"Kid, take off your clothes, except your inner pants, and lie down with your chest facing the ground, you will be handcuffed to the table, before that in order to avoid anyone hearing your screams, I will gag your mouth. After that, we will begin."
Ainz nodded, and began to take off his clothes, as as he was pulling his trouser, Bruce exhaled softly and held him on his shoulder, before saying with a soft voice.
"Kid, I know this is your decision, but I hope you can rethink the risk involved in it. I don't want you to do something you might regret for the rest of your life. If you lie on that table, there will be no going back, in case you want to quit, this is your last chance."
Ainz felt a bit of warmth hearing those words, he could tell they weren't said because he was afraid of the consequences of him dying, but from genuine concern about him, however, he had already made up his mind, so he simply answered.
"There has never been a way back for me, master, you know this. Not since the day I was betrayed, and abandoned."
As Bruce heard what he said, he frowned for some reason he felt deep meaning to those words, but coming from a kid, he couldn't understand how he was betrayed, even if his father had left him and his mother, it didn't mean he was abandoned.
Bruce simply sighed, and then nodded for him to start undressing, eventually Ainz was half naked, after he was done he went ahead to lie down on the metal table, spreading both his arms and legs, while his chest was facing the ground.
Bruce looked at Ainz, and felt pity for the kid, the world itself was fair but that wasn't the case for humans, they would discriminate against anyone at the slightest given opportunity, over talent, bloodline, methods, and wealth.
'He was fortunate to have been born into a wealthy and powerful family, but his fate was not as lucky to be in the right family, anyone who seeks power must also put their life on the line to obtain it, but those who are from powerful families still have it easy than the rest, this kid even without support is still willing to risk it all.'
He looked at the kid who had just completed his twelve-year-old, not too long ago, lying on the rusty metal table, used in all kinds of torture. Closing his eyes, he steeled his resolve and opened them as he went close to him.
First, he handcuffed both his arms and legs and then pulled the chains that were mounted at his side to stretch out his body, and then he took out a piece of cloth from the side of his pants, and put it in Ainz's mouth.
"Please don't die, kid."
Bruce said, and then began to destroy the eight acupoints in his body as written in the eight gates of asura, putting his hand on Ainz's back, he exhaled and began to pour in all his concentration, his senses scanned every part of his body, searching for a precise coordinate to his acupoints, and once he found them, he brought out eight golden needles from a bag, after coating them in his mana he began to insert them on his back.
"Kid, I am going to start."
As soon as he heard his voice, Ainz tightened the grip on the chains, and called out the system as he activated wyvern regeneration, and then began to shut off his pain receptors, preparing himself for the wave of pain that was about to come.
CRACK!
[Wyvern regeneration activated!]
