It has the same effect as "Snake Eye Potion".

However, the "snake eye potion" only allows wizards to see living creatures.

There are references, so logically speaking, it shouldn't be difficult.

Harry thought so. He optimized the formula of the Snake Eye Potion and prepared the Cat's Eye Potion, but the result was a bit bad. The brewed thing was not only more palatable than the Snake Eye Potion, but also had slightly better effects on those living creatures.

Except that the red light it emits is more intense, it is no different from the snake eye potion.

even……

After the potion was successfully brewed, the white seagulls that were supposed to have some special effects were assimilated, and the strong effects disappeared and became milder.

Sword oil has not encountered such a problem.

Ideas or methods?

During this time, he went to the library more frequently, often applied for approval from Lu Ping, and read every banned book on potions.

Until the arrival of February.

After spring begins, the snow begins to slowly melt.

There were some birds appearing at the edge of the Forbidden Forest from time to time. Harry put them down for the time being. There were more important things that he needed to face.

Professor McGonagall's confinement class.

Harry waved his wand, and his arms twisted and transformed into swan wings smoothly.

McGonagall applauded him: "Great human transformation."

"It would be great if Wood could be as good as you." She sighed, "His current level is still far behind the 'O' of nwets."

"It's rare to see a Gryffindor who is not so good at transfiguration." Harry nodded and sighed.

McGonagall: "No, 'E' is already very good, and Aurors only require to reach this level."

"No wonder." Harry suddenly realized, "I thought Aurors would be very demanding."

Mag looked at him angrily, waved his wand, and lifted the transformation spell on his body: "This ends today's class. Next week we can start trying to deform the torso."

"Professor, maybe I can try the Animagus now?" Harry asked tentatively.

Mag was startled, then smiled: "Your current level is indeed enough to contact Animagus, but are you ready?"

"I should be ready." Harry nodded. In addition to his father's notes, he also read a lot of books about Animagus in the library.

A ceremony that lasts at least a month and may take up to a year.

"No, it's not magic preparation." Mag's face was straight and his tone was serious, "Animagus is not difficult. Many wizards have such abilities."

As she said that, she paused.

"Although there are only eight Animagus in this century, there are many people who have the ability to master Animagus."

"Professor Snape, Pomona, Filius, Albus, they all have this ability."

"I know at least ten people who could try this spell, but none of them have. Do you know why?"

Harry frowned and thought, and answered hesitantly: "Are you afraid that the animal you become will not be the thing you like?"

"If my Animagus were a mouse, I don't think I would be able to accept it."

McGonagall looked at Harry in surprise and shook her head: "How could it be this? It's the Ministry of Magic."

"Every Animagus must be registered with the Ministry of Magic. Many wizards don't like this. They prefer the feeling of freedom."
