A day at Hogwarts

Ten days before leaving school, Charles was finally able to cast the Flying Curse without a wand, but he had to whisper the spell.

"It's pretty good." Jack touched his head with satisfaction, "It's fine to do this."

"I remember there is a saying among you Muggles that the effects of force are mutual, right?"

Charles replied, "Yeah, what's up?"

Jack pointed to the cliff in the distance and said, "Have you ever thought about what would happen if you cast the Flying Curse on that mountain?"

Charles was taken aback for a moment, and this involved his own blind spot of knowledge.

Then Jack played him a trick.

The old man stretched out his hand towards the cliff, and the next moment, he flew to the other side of the cliff.

Charles watched in bewilderment as Grandpa was swinging around the cliff like Spider-Man, and seemed to use a throwing spell to slow down when he flew back.

"Do you understand?" Jack asked.

Charles nodded silently.

"It's okay."

Jack restored the stone smashed by Charles practicing magic on the ground into a huge boulder, first cast the floating spell, then jumped up and cast the flying spell on the opposite cliff, and then he flew over with the stone.

When Jack came back, he said triumphantly, "Magic, it's amazing."

Charles continued to nod.

"Okay." Jack did a warm-up exercise, "It's time to teach you the Avada Kedavra."

Charles shouted in surprise: "No way! Do you really want to learn this? If you are found out, you really want to enter Azkaban!"

"It's okay." Jack didn't look like joking, "Just don't let people find out."

Charles had a black thread, and he understood what he meant. Killing everyone who saw it meant that no one saw it.

Jack said to him seriously: "Hogwarts is very dangerous. No one can predict what will happen to that two-hole socket. No matter how unwilling you are, you must have a dog-beating stick to save your life."

Charles died before, and he almost died again after he finally survived, so he cherished his own life, hesitated for a long time, and finally agreed.

He thought in his heart that as long as he didn't use it indiscriminately and only used it to save his life, it should be fine.

Jack didn't start talking to him about how to cast a spell, but sat down with him on the edge of a cliff, and after a moment of silence, he said, "You know, I've read your memory, but I haven't finished it."

Charles nodded.

Jack continued: "Soul, heart, mind, and the three views you mentioned. I can't tell the essence of these things, but I know that black magic can affect people's minds, but I don't know how."

"It's like the beach below, the water is very shallow at the beginning, as you walk slowly forward, the water will slowly become deeper, it is not easy to detect, it makes people feel that they can still go forward, but in the end it will suddenly change. It becomes an abyss, and people kick it into the air and fall, and they can no longer float up."

"Some people with a strong will are prepared from the beginning and can resist this temptation in their hearts, such as me."

"Your will...I can only say that I felt your pain at the beginning, and this pain made me run away, not daring to go any further."

"I believe that your will is strong enough to resist the influence of black magic."

Charles didn't speak, just sat there quietly like a stone man, watching the seagulls circle the sea.

Perhaps because of the time travel, he always felt that he was clear and vague about the things in his previous life, which was very contradictory.

"Grandpa," he asked suddenly, "why did you learn the Avada Kedavra in the first place?"

Jack froze for a moment, turned into a stone man just like him, and replied after a long time: "The excuse I gave myself was to comfort my friend."

"At that time, he had just experienced the greatest tragedy in his life..."

"Well... Looking back now, it seems that everyone was wrong."

He touched Charles' head as he spoke, and continued: "Child, in the future, if you and your friends and family members have any thoughts in your heart, you should speak them out, communicate more, and understand each other. You might as well be more tolerant."

Although Charles didn't understand what happened before, he understood what the old man meant and nodded slightly.

"Get up," Jack stood up, "start learning. Black magic spells, including Avada Kedavra, have one thing in common. The caster must be determined when casting the spell. It must kill the opponent, the curse of the wrong tone is just a light punch."

"That is to say..." He found an adjective that Charles could easily understand, "A tsundere person cannot use this kind of spell well."

Now Charles understood completely.

"Three days." Jack stretched out three fingers, "I only teach you this spell for three days. If you are talented, you can master it in these three days. If you can't master it in three days, you won't be able to learn it in thirty years." meeting."

"After this time, I will teach you some fighting skills."

Charles started learning the Avada Kedavra curse." He noticed something was wrong when he watched the old man demonstrate, "Isn't this spell green? Why did it turn red? "

Jack said with some surprise: "Aren't you afraid of entering Azkaban, so I changed the color."

Charles shook his head and said, "But this looks almost the same as the Cruciatus Curse."

Jack thought for a while, and it was true. The difference between using the Killing Curse and the Cruciatus Curse was only to enter Azkaban and live in an odd-numbered room or an even-numbered room.

"Then let me think about it." Jack thought about it there, "you go and play for a while."

Instead of playing, Charles went to the kitchen to prepare lunch.

Lunch is very simple, traditional fried fish and chips, if you see this meal just after crossing, you will definitely not be able to tell if Germany is still bombing Britain.

While eating lunch, Jack said happily: "I've solved the problem. I'm sure no one will see that it's Avada Kedavra, and it won't be regarded as the Cruciatus Curse."

Charles breathed a sigh of relief, and admired the old man's magical attainments in his heart.

Just after lunch, when Jack demonstrated Avada Kedavra, Charles almost spat out a mouthful of old blood.

"Why is it rainbow-colored?" The corners of Charles' mouth twitched, "That's... well... I don't know what to say."

Seeing that he was dissatisfied with one or the other, Jack said angrily, "Then change it to pink?"

Charles broke out in cold sweat all of a sudden, and said hastily, "Just a rainbow, it's pretty pretty."

"Hmph!" The old man continued to be angry, "I'll teach you pink!"

"Okay then." Charles looked dejected, "Then I'll take your wand and ask the previous principals, and I'll tell you that the Avada Kedavra used by the owner of this wand is pink."

Jack was almost mad at him.

Eventually, Charles began to study Avada Kedavra Rainbow.
