"As for the other question, the usual age at which the human body has completely formed its mana core is fifteen. At the same time the three centers of powers are deeply connected and balance themselves, however, like I said you're a unique case, besides the fact you are not a complete human but also an elf, you have also managed to cultivate the body revolving technique which might have probably sped up the process of forming your mana core, and from what I know you might have also gained some growth in body cultivation.
Hearing what Bruce said, Ainz couldn't help but wonder what his expression would be like if he told him he already formed his mana core when he was no more than five days old? Although he would have loved to see his expression, he didn't want to scare him shitless and end up blowing his cover.
Again, just like he said he might have gained some growth in cultivation, however, if he was to be honest, he probably already gained years of growth, it could even be said he was already a half cultivator, even his body was also likely stronger than the guards under his master.
'This means that I can accelerate the process by training the other two centers of power since I have already formed a mana core. But wait, what if I train the three centers of powers all three at the same time, how fast will my growth be? Doesn't that mean I will be able to easily break the limits of my body?'
Ainz fell into contemplation, he couldn't help but glance at his master from the corners of his eyes, he would have loved to ask him more about the three centers of power but it was likely he wouldn't give him an answer.
After a while, he decided to give it a try knitting his bro together as if he was confused, he opened his mouth and was about to ask, but was interrupted.
"I know you probably have questions but let's put that aside for now, and focus. Cultivation is not just about becoming strong, or understanding your body but an act of understanding the world's energy which is mana, and then taking it in as a nutrient to nourish the body, just like normal humans cook and eat their food.
"Therefore, since the three centers of power are connected, does that mean empowering one will affect the other two? Yes, it's also true that leaving behind one will slow the growth of the other ones, since they are not only connected, but intertwined. But like I said, let's leave that for now and focus."
Bruce said while sitting on the ground, at this point, he was no longer sweaty, and on his hand was a pile of sheets that looked worn out and old.
"These are the training methods for the sea of consciousness, martial arts, and body cultivation techniques. These are training methods I have specifically chosen for you, that don't need mana core.
"Within these sheets are the general descriptions of the techniques, so come forward and then read them carefully, don't forget to pick only those that match your traits and needs, don't be greedy kid."
Bruce said as he gave him the corner eyes, anyone who knew what the kid had been up to would understand why he gave those eyes, hearing what he said Ainz gave an embarrassed look outwardly, while, he was thinking if there was a way he could use the system to copy everything.
Ainz drew closer to him, and he sat close to him with the sheets now in his hands with a weird ass smile on his face, looking at his face Bruce couldn't help but think to himself,' So he could also show such an expression? This fucking kid didn't even bulge when I told him I wanted to train him.'
Shaking his head, Bruce added one more time:
"Take note these are just temporary methods before you form your mana core, these techniques will only last before your mana core is fully formed, except the rest such as the sea of consciousness and martial arts, while for the body cultivation technique when you finally form your mana core you will have to change it, if you want to experience the real power of a cultivator, so, for now, you are limited to this one."
After he said that, he lay on the ground and then closed his eyes as if taking a nap, as far as he was concerned he had explained what Ainz needed to know, now it was left to him to decide. Looking at Bruce acting as if he was sleeping, Ainz placed his thoughts at the back of his mind and began to quickly go through them.
Bruce couldn't help but smile, he didn't need to see what the kid was up to before he could tell what the kid was doing, he was sure if it was left for the kid, he would have longed consumed the sheets in his hands. From what he had heard from his lord the kid's mother had once been a powerful wizard, to the point where she would have rivaled the patriarch in the future, although he was curious but it wasn't his business.
'I wonder how scary he would have become if the main family had taught him how to become a wizard'
