Modifying Avada Kedavra

Chapter 7: Modifying the Avada Kedavra

Ten days before school started, Charles could finally cast the Accio Charm without a wand, though he had to whisper the incantation.

"Pretty good," Jack said, patting his head with satisfaction. "You've done enough to move on."

"I remember Muggles have a saying about the law of action and reaction, right?"

Charles replied, "Yes, what about it?"

Jack pointed to a distant cliff and said, "Have you ever thought about what would happen if you used Accio on that mountain?"

Charles was taken aback; this was outside his knowledge base.

Then Jack showed him something slick.

The old man reached out towards the cliff, and the next moment, he flew towards the cliff face.

Charles watched, dumbfounded, as his grandfather swung back and forth on the cliff like Spider-Man. When he flew back, it looked like he had used the Projectile Charm to slow down.

"See clearly?" Jack asked.

Charles nodded silently.

"You can also do this."

Jack restored the broken stones Charles had shattered while practicing magic into a single boulder. He first cast the Levitation Charm, jumped onto it, and then cast Accio at the opposite cliff. He flew over along with the boulder.

When Jack returned, he said proudly, "Magic, isn't it amazing?"

Charles continued to nod.

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

Charles exclaimed in surprise, "No way! Are you really going to learn this? If we get caught, we'll really go to Azkaban!"

"It's fine," Jack said, not joking. "Just don't let anyone find out."

Charles's face went blank. He understood what Jack meant: eliminate anyone who sees it, and then no one will have seen it.

Jack said to him sternly, "Hogwarts is dangerous. No one can predict what that two-holed socket will do. No matter how unwilling you are, you need a dog-beating stick to save your life."

Charles had died before and barely survived a near-death experience. He cherished his life and, after much hesitation, finally agreed.

He thought to himself that as long as he didn't misuse it and only used it to save his life, it should be fine.

Jack didn't start teaching him the incantation. Instead, they sat down by the cliff, and after a moment of silence, he said, "You know, I've seen your memories, but I didn't finish them."

Charles nodded.

Jack continued, "The soul, the mind, thoughts, and what you call values – I can't explain their essence, but I know dark magic can influence a person's mind, though I don't know how."

"It's like the beach below. The water is shallow at first. As you walk forward, the water gradually gets deeper, making it hard to notice, making you feel like you can still go forward. But eventually, it suddenly becomes an abyss, and you fall in, never to surface again."

"Some people with exceptionally strong wills are prepared from the start and can resist this temptation internally, like me."

"Your will... I can only say that I felt your pain back then. That pain made me flee in panic and dare not go any deeper."

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

Charles remained silent, sitting there like a stone statue, watching seagulls circle over the sea.

Perhaps because of his transmigration, he always felt that his memories of his past life were both clear and blurry, a contradiction.

"Grandpa," he suddenly asked, "why did you learn the Avada Kedavra back then?"

Jack froze, becoming as still as a stone statue as Charles, and after a long time, he replied, "My excuse at the time was to comfort my friend."

"He had just experienced the greatest tragedy of his life..."

"Alas... Looking back now, it seems everyone made mistakes."

As he spoke, he patted Charles's head and continued, "Child, in the future, if you have any thoughts about your friends or family, speak them out. Communicate more, understand each other, and perhaps be a little more tolerant."

Although Charles didn't understand what had happened before, he understood his grandfather's meaning and nodded gently.

"Get up," Jack stood up. "Let's start learning. Dark magic spells, including Avada Kedavra, have one thing in common: the caster must have a firm will when casting the spell. If you intend to kill the other person, you must kill them. Half-hearted spells only deliver a light punch."

"In other words..." He found a term Charles could easily understand, "Tsundere people can't use this kind of spell well."

This time, Charles completely understood.

"Three days," Jack held up three fingers. "I will only teach you this spell for three days. If you have talent, you will grasp it preliminarily within these three days. If you can't master it in three days, you'll never learn it in thirty years."

"After this time, I'll teach you some combat techniques."

Charles began learning the Avada Kedavra.

"Grandpa," he noticed something was wrong when his grandfather demonstrated, "isn't this spell supposed to be green? Why did it turn red?"

Jack said with some surprise, "Aren't you afraid of going to Azkaban? So I changed the color."

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

Jack thought about it. It was true. The difference between using the Killing Curse and the Cruciatus Curse was only whether you lived in an odd-numbered or even-numbered cell in Azkaban.

"Then let me think," Jack pondered. "You go play for a while first."

Charles didn't go to play but went to the kitchen to prepare lunch.

Lunch was simple: traditional fish and chips. If someone had seen this meal right after crossing over, they wouldn't have been able to tell if Germany was still bombing Britain.

While eating lunch, Jack said happily, "I've already solved the problem. No one will be able to tell it's the Avada Kedavra, nor will they mistake it for the Cruciatus Curse."

Charles breathed a sigh of relief, deeply impressed by the old man's magical mastery.

However, after lunch, when Jack demonstrated the Modified Avada Kedavra, Charles almost spat out a mouthful of blood.

"Why is it rainbow-colored?" Charles's mouth twitched. "This... sigh... I don't know what to say."

Seeing his dissatisfaction, Jack said petulantly, "Then should I change it to pink?"

Charles broke out in a cold sweat and quickly replied, "Rainbow is fine, it looks quite good."

"Hmph!" The old man continued to sulk. "I'll teach you the pink one!"

"Alright then," Charles said with a dejected look. "I'll take your wand and ask the past headmasters, telling them that the Avada Kedavra used by the owner of this wand was pink."

Jack was almost angered to death by him.

Finally, Charles began to learn the Rainbow Avada Kedavra.
