In the castle at night, only thin candle flames illuminated the paths. A faint shadow made its way towards the Restricted Section.
After reading the materials in the Room of Requirement, Light went back to the dormitory. After his dorm mates had fallen asleep, he sneaked out again.
Under the cover of night, he soon reached the Restricted Section!
Taking out the book list given by Professor Snape, Light started searching for books on the shelves.
*One Hundred Ways to Die in Transfiguration*, *Detailed Explanation of Funny Transfiguration Mishaps*...
Looking at the book list given by Professor Snape, Light became more and more confused.
"Damn! Professor Snape must have prepared this list on purpose to stop me from doing stupid things!"
Light complained in his heart, but still quickly picked up the books from the shelves according to the list.
At the same time, he also kept a few books about ancient rituals.
After gathering all the books, Light took them to the Room of Requirement and began to read slowly.
Instead of starting with "Animagus", he cautiously began with the precautions of Transfiguration and how to handle abnormal situations.
...
Early the next morning, rubbing his sore eyes, Light ate breakfast while secretly vowing not to stay up all night again.
As soon as this thought popped into his head, Light felt an inexplicable sense of familiarity. 'I seem to have been in this situation before!'
While Light was in a daze, Hermione urged him to eat quickly because they were going to be late for class!
The four of them rushed and finally took their seats in the classroom before Professor Binns, the History of Magic professor, arrived.
After catching up on sleep in Professor Binns' class, Light continued to study the books about Transfiguration in the next Spells class.
Through continuous study, he gradually confirmed his conjecture about 'the difference between the Magic Power of wizards and magical creatures'.
At the same time, he decided to make a bottle of 'Animagus potion' for analysis before attempting to transform into a magical creature.
After several days of hardworking study, Light finally decided to tackle the ultimate mystery of Transfiguration, 'Animagus'.
After a day of classes, Light went to the Room of Requirement and took out the banned book *Species Transfiguration* and started flipping through it!
"Practicing Animagus is not easy. First of all, practitioners must have a proficient understanding of Transfiguration to avoid danger!"
"Secondly, one must keep a humble heart. Don't blindly think you are a genius. Don't be over - confident and think you are special. Don't think you can transform into a magical creature easily!"
"Finally, this Spells requires luck. If you fail once, don't try it a second time. It's the choice of fate!"
After reading the author's warnings and the consequences of not following the rules, Light frowned at the moving pictures on several pages of the book.
All the pictures showed people who had violated the warnings of Transfiguration. Each picture featured a half - human, half - creature with a distorted body and a hideous expression.
"I can understand the first two points, but why can't I try it a second time if I fail the first time? I don't quite believe in the so - called choice of fate!"
After thinking for a long time, Light continued to read, full of questions, intending to find the answer in the following method of making the potion.
"Step one of practicing to become an Animagus requires holding a mandrake roots leaf in your mouth from one full moon to the next. You mustn't let the leaf leave your mouth during this period, or you'll fail!"
"Step two, make the leaf into a potion and bury it in a place completely isolated from the outside world and sunlight!"
"Next, take it out before a thunderstorm with thunder and lightning. If the potion is blood - red, it means all the previous operations were successful."
"Finally, drink the potion immediately when you take it out and transform during the thunderstorm."
He murmured to himself, "That's it!"
Puzzled, Light kept flipping through the pages. Instead of solving his questions, more and more popped up in his mind.
"Why do we have to hold the mandrake roots leaf? Why do we have to transform during a thunderstorm?"
After flipping through the book several times, Light gave up the idea of finding answers in the book and decided to practice becoming an Animagus himself to solve the problems.
After making the decision, Light went to seek investment!
Under Professor Snape's vacant gaze, he got several materials for making the potion, especially more than a dozen mandrake roots leaves.
Amid Professor Snape's obviously dissatisfied and hoarse scolding, Light was kicked out of the office.
Holding a bunch of potion materials in his hand, Light quickly walked to the potion - mixing room transformed by the Room of Requirement and put the materials down.
Then, Light couldn't wait to put a mandrake roots leaf in his mouth.
There was nothing special when the leaf first entered his mouth. But with each swallow of saliva, Light keenly felt a subtle power seeping into the leaf.
Just like this, Light spent a day with the leaf in his mouth, and it was not an easy day for him. He was afraid of swallowing it while sleeping and also while eating.
However, the data collected during this day had already allowed Light to understand all the secrets of becoming an Animagus.
That night, Light went to Professor Snape's office and began to explain his full understanding of this Spells and the potion, reporting his progress to the client.
"Mandrake roots have the wonderful power to absorb spirit, but since it has lost its roots, it can't store spirit power."
"The spirit power that can't be stored is transported to all parts of the body along with saliva. During a day - night cycle, it then returns to the leaf."
"After thirty such cycles, the leaf contains all the information of the body and spirit."
After listening to Light's explanation, Professor Snape crossed his left arm over his chest and put his right hand on his lips, showing a thoughtful expression.
Then, his vacant gaze fell on Light again, and he said hoarsely:
"I remember you promised to tell me before doing any experiments!"
Hearing Professor Snape's words, Light's proud expression froze, and he forced a smile, saying, "This isn't an experiment. It's just getting the raw materials ready."
Professor Snape stared at Light expressionlessly, obviously not buying his excuse. He spoke in a low voice:
"I remember it's not the full - moon time recently. Why did you suddenly start?"
Isn't this an experiment?"
Caught in the act, Light quickly made an excuse.
"It's because we need to figure out why we have to hold the leaves in the mouth during the full moon! And why it can't be done at other times of the month. Besides, it's just holding the leaves in the mouth. It's not dangerous."
After hearing Light's excuse, Professor Snape didn't press the issue and continued to ask, "Then why do you start the preparation when it's a full - moon?"
Hearing Professor Snape's question, Light knew he had managed to get through this. Secretly pleased, he then reported his conclusion.
"Because when it's a full - moon, the spirit and the body become more active! The body has weaker resistance to the information that mandrake roots absorb from the spirit and the body!"
