After thinking this, Ainz shifted his attention back to the sheet in his hand.
'According to the description of the technique, I can say the advantages of this technique are pretty good and well balanced with the wyvern king technique, I just don't know if it is as good as it was written.'
He kept thinking for a while before looking at Bruce, at this moment there was a thought he had in his mind.
"Master, how long does it take for a cultivator with mana core to obtain a rank 4 body with the orthodox way?"
Bruce stared at Ainz for a moment, as if hesitating on whether to answer or not, and then eventually after a while he decided to simply tell him the truth.
'"If as a cultivator, you are cultivating a technique to achieve rank 4 body, skipping rank 1 and 2, then it takes around ten to twenty years, depending on your aptitude and talent."
Ainz fell into contemplation, if he was to compare his body then it would be somewhere around rank 1 to 2, the reason he said so was he had been cultivating the wyvern king technique since he was a baby, and the fact he was also a child of wyvern, which meant he already had the bloodline of a powerful magical beast running through his vein.
All these were achieved without a normal cultivation technique, and now what if he cultivated both the normal cultivation technique and the wyvern cultivation technique, how strong would his body become then? It wasn't just a matter of addition, but the fact there was the possibility his body could become rank 4 when his mana core was rank just 2.
"What's the current level of my body? How long will it take with the orthodox method with a mana core and while training a rank 2 method, and then how long if I cultivated this technique?"
A storm of questions came out of Ainz's mouth, since he needed to understand this world and then his body, he wanted to know about them as much as possible, before taking any worthwhile risk.
"Right now, your body is below quasi-rank 1 cultivator, since your body is still growing and new to cultivation, and you cultivated a method without mana core, the results will be poorer and slower when compared with the benefits provided by the cultivation method of the same rank which uses mana core.
"The same thing applies to the rank 2 methods, if you start training in one now, by the time you form your mana core, you would have gotten a body of almost a rank 2 cultivator, and you will probably reach the third rank in five to nine years, and if you were to use the unorthodox method, it might take you between three to five years to complete the process."
After listening to what he said, Ainz was surprised that according to Bruce it would take him five to ten years to achieve a rank 3 body, but since his body was almost rank 2 it would take at most five years, which was not at all that bad.
At the same time, he wondered why a rank 3 cultivation method wasn't placed among the body cultivation methods he was given just like the martial art? Except his master was hiding something from him, otherwise, there was no way he would want him to cultivate something so dangerous if he could avoid such risky methods.
At first, after hearing what Bruce said, he had begun to contemplate whether he should ask for a rank 3 cultivation method instead or how he could get it, but now after thinking about it Ainz raised his head to look at his master, and realized his eyes seemed like they were trying to hide something.
Then he thought of something and asked:
"How can I get a rank 3 cultivation method?"
This time he noticed, Bruce was finding it hard to reply to his question, after seeing his expression he canceled the last ounce of hesitation he had, and handed the cultivation method to Bruce, he didn't need to think much to figure out it had something to do with his position and inner circle again.
"Master, I chose this as my body cultivation method."
When he saw Ainz handing the sheet to him, Bruce felt bitter for the kid, kid's his age in the inner circle would have been given better cultivation techniques, and wouldn't have needed to risk their life for any cultivation methods, but because he wasn't part of the inner circle if he wanted to become strong he needed to not only prove himself but risk his life as well.
After staying silent for a while, he straightened himself up and collected the sheets in Ainz's hand, before he began talking:
"I hope you don't regret your decision, even though I accept your decision and have agreed to train you, but first, I want you to train your mental energy first for six months, and if after that time, I don't see noticeable result, I will take it that you are not ready, and will not allow you to cultivate the cultivation method.
"The second condition is that you will have to be open with me, and show me every result when you cultivate, will you accept?"
Ainz looked at him, for a moment just like he thought Bruce was really afraid of him cultivating the cultivation method.
