Time passed quickly, and before he knew it, it was already Saturday.
Lynn arrived at the Defense Against the Dark Arts professor's office as scheduled after lunch. He held a copy of "Ancient Runes: A Simple Introduction" in his left hand and knocked on the office door with his right hand.
"You're quite punctual. Come in!" Professor Green opened the office door and let Lynn in.
Lynn walked into the Defense Against the Dark Arts professor's office and looked around curiously.
The office was divided into three areas under Professor Green's arrangement. The outermost area was a desk sandwiched between two bookshelves. This seemed to be the place where Professor Green graded students' homework and prepared lesson plans.
Further inside, there were dozens of cages covered with red cloth stacked together. Lynn guessed that these were the teaching materials prepared by Professor Green, just like the Acromantula hatchlings on Monday. These teaching materials were probably caught by Professor Green from the Forbidden Forest.
As for the innermost part of the office, it was filled with a large number of alchemical equipment, with countless metallic lusters flashing. Lynn also saw a group of runes flashing red light on a prism-shaped device, which was constantly spraying flames upward.
"Have you remembered the 'Ancient Runes: A Simple Introduction' that I asked you to study on Monday?" Professor Green closed the office door, waved his wand, and transfigured a chair, motioning Lynn to sit down.
Lynn obediently sat down and nodded, "I remember them all."
So, Professor Green asked a few ancient runic words contained in the "Ancient Runes: A Simple Introduction", and Lynn answered fluently.
"Very good, take these." Professor Green nodded with satisfaction and handed two slips of paper to Lynn.
Lynn looked down and saw that one of the slips was densely written with a book list, and the other slip bore Professor Green's signature.
"These are the books on alchemy that you need to study on your own. You can read them in order. As for the last few books, they are only available in the Restricted Section of the library. You can borrow them with the signed note I gave you," Professor Green said lightly, with a gleam in his light blue eyes. He didn't seem to worry that Lynn would misuse his signed note.
"Okay, Professor Green!" Lynn put the slips away.
Professor Green turned around, walked across the desk to the deepest part of the office, and stood in front of the prism-shaped alchemical apparatus that Lynn had seen before. He turned his head and said, "Come here, Lynn."
Lynn stepped forward and came to Professor Green's side.
In front of the two of them, this group of red runes was still releasing flames. The flames brought a burning warmth, but unexpectedly made Lynn feel comfortable.
"You think that these endless flames are all produced by this set of runes, right?" Professor Green pointed at the rune set and asked.
Lynn thought about it and nodded, "Yes, professor."
There was nothing else on this device except this set of runes. Lynn did think that this flame was produced by this set of runes. Moreover, Lynn also felt the emanation of magic from these runes.
Hearing this, Professor Green smiled and shook his head. He pulled out his wand and gently tapped the device. The bottom of the prism suddenly cracked, revealing a glowing crystal inside.
This crystal continued to shine, and waves of magic power also radiated from it.
Obviously, this crystal was the real energy source of the flame.
"This is a product I made by imitating a Philosopher's Stone, but it doesn't have the power of turning lead into gold or granting immortality like a true Philosopher's Stone. It can only store our magic power and release it when we need it," Professor Green explained. "But, after this demonstration, what do you understand?"
Lynn tentatively answered: "Nothing comes from nothing. If you want to get something, you must sacrifice something of equal value?"
Professor Green nodded with satisfaction: "Yes, remember, the most fundamental law of alchemy is the 'Law of Equivalent Exchange'. If you want to gain something, you must pay an equal price. You must sacrifice to achieve your goal. This is a principle that every alchemist must follow during the alchemical process. If you have read books related to alchemy, you should also know this basic rule."
"Alchemy is different from regular magic. It is not the other side that you can reach by simply waving a wand. True, it cannot make us obtain what we desire easily, but its value is greater. It can grant you eternity!"
The gravity in Professor Green's eyes was replaced by a noble and faith-filled light, and his words were full of conviction.
"In addition, there are two major taboos in alchemy that you must remember," Professor Green's expression suddenly became serious.
Lynn guessed: "Time travel and tampering with souls?"
Hearing this, Professor Green shook his head and said: "Those are taboos in magic. There are only two taboos in alchemy. One is that you can never attempt to usurp the power of God, and the second is that human transmutation is forbidden."
Lynn nodded thoughtfully.
Since the original books repeatedly emphasized the dangers of meddling with time and souls from multiple aspects such as the Time-Turners and Voldemort's Horcruxes, Lynn subconsciously thought that these two were the taboos of alchemy.
But Professor Green corrected him.
Yes, although magic and alchemy had some commonalities, they were two different systems and could not be generalized.
And the Time-Turner itself was an alchemical product. If time manipulation was truly a taboo in alchemy, then there would be no Time-Turners.
After explaining to Lynn the basic rules and two taboos of alchemy, Professor Green also talked about many ways to study Ancient Runes and then the foundational knowledge of alchemy. This allowed Lynn to enter the realm of alchemy without any obstacles after mastering all the ancient runes.
"Take this, it can weaken your magic power to one-tenth of its original strength."
After covering the theoretical knowledge, Professor Green handed another bracelet to Lynn.
Seeing the crystals embedded in the bracelet, Lynn couldn't help but exclaim: "Magic-Dampening Stones?"
You know, among the achievements of Professor Green recorded on the Chocolate Frog card, there is the discovery of the Magic-Dampening Stones, and the publicly known effect of Magic-Dampening Stones is only to weaken a wizard's magic power by 10%, and that is only possible with a Magic-Dampening Stone the size of a Quaffle.
However, the Magic-Dampening Stones embedded in the bracelet were only the size of a fingernail, but they could achieve the effect of suppressing Lynn's magic power by 90%!
Could it be that the facts were just as Lynn analyzed at the beginning, that the Magic-Dampening Stones announced by Professor Green to the public were actually a weakened version, and the reason why the initial version of the Magic-Dampening Stones was not released was to prevent them from being banned due to fears of the major wizarding ministries?
