Hearing the question, Knave went into a deep thought process trying to uncover the mystery behind the mysterious technique used by the elder.
Logically thinking the method used by the elder had been done after the quenching process described by the books in the library, so assuming the possible answer is the last process of the alchemy cannot be considered wrong but it just didn't seem right to him.
If the answer was so simple the elder wouldn't have asked him the question, so the answer which came to his mind was "Auxiliary alchemy techniques", this techniques we're created to assist in the alchemy process to improve the chances of pill formation.
Normally, during the alchemy process, a person can make at most 10 pills with one set of ingredients, but that is only for the Masters who have thoroughly understood the pill recipe that they are preparing to the very tiniest feature.
For those who have not, making 5 to 6 pills of good quality can be considered as a successful alchemist master.
After considering his answer thoroughly Knave looked towards the elders smiling face and said, "Elder, according to my deductions the technique that you performed during the alchemy process is an auxiliary technique designed for alchemy so as to increase the chances in production of in during alchemy"
Elder Fryer listening to his answer nodded his head approving of his answer and said, "You see my child, during the alchemy process the four steps that are required to be done, leaving the first one that compels you to learn on your own to acquire the herbal knowledge the rest all have auxiliary techniques to help the alchemist in a concoction of the pills.
For example, my auxiliary technique is useful during the fourth process of pill formation, as you had guessed but this technique requires the complete attention while performing it or if something goes wrong during the process of this technique may lead to horrible results.
Such techniques that are used as a catalyst during the alchemy process are highly valuable to an alchemist and in the academy, they are thought only to those who are at high posts in their sections, but there can be an exception to such rules depending on certain situations.
While from what I had heard from my friend elder Prune, you have selected a cultivation manual which focuses on alchemy as it's major and its auxiliary effects are useful during the quenching process.
What I have is not a cultivation manual but a simple auxiliary technique which will not only prove useful for the alchemy process but also during fights in the future." the elder spoke to Knave and tried to vanquish any doubts he had in his mind towards his technique.
Hearing this Knave was quite delighted as according to him in the future the Green flame core technique might prove to be quite useful considering his unique situation.
But he still had his doubts, because the elder was being too good to him without any reason whatsoever, thinking about it for some time he thought asking the elder directly would be much better as he didn't want to become part of some schemes in the Academy.
From what he could tell there were three scenarios for why the elder was being so good to him.
First, he really appreciated him as he had told the other elder in the classroom. Second, he had some connection to Vanessa or her mentor and they were on good terms so he was being recruited on Vanessa's bequest.
Lastly, the opposite of the second reason was also possible in which the elder had a vendetta against Vanessa and her mentor and wanted to get to them by causing harm to him.
Considering his facts for the final time he looked towards the elder and said,
"Elder, has my sister send you to take me as a disciple?"
"So, you finally could not hold the doubt in your mind. It's understandable that you would be doubtful after somebody shows so much good faith towards you without any rhyme or reason, if I were in your shoes I would also have doubts of my own. I would rather be surprised if you didn't have any considering you are her brother, leaving that aside, to answer your question I am....
