Modify Avada Kedavra

Modify Avada Kedavra

With ten days left until school started, Charles could finally manage to cast Accio Charm without a wand, though he still had to softly recite the spell.

"Not bad." Jack was quite satisfied as he ruffled his hair. "This is good enough for now."

"I remember you Muggles have a saying that goes something like, 'Forces act mutually,' right?"

Charles answered, "Yeah. Why?"

Jack pointed at the distant cliff. "Have you ever wondered what would happen if you used Accio Charm on that mountain?"

Charles froze. This clearly touched on a blind spot in his knowledge.

Then Jack showed him a neat trick.

The Old Man stretched out a hand toward the cliff. The next moment, he flew toward it.

Charles stared blankly as his grandfather swung back and forth along the cliff like Spider-Man. When he flew back, he seemed to have used Projectile Charm to slow himself down.

"Understand now?" Jack asked.

Charles nodded silently.

"You can do it this way, too."

Jack restored the rocks Charles had smashed apart while practicing magic into a boulder. He first cast Levitation Charm, then jumped onto it and cast Accio Charm toward the opposite cliff. He and the boulder flew over together.

After Jack returned, he said smugly, "Magic is amazing, isn't it?"

Charles continued nodding.

"Alright." Jack did a warm-up exercise. "It's time to teach you the Killing Curse."

Charles shouted in surprise, "No way! We're really learning this? If we're discovered, we'll actually be sent to Azkaban!"

"It's fine." Jack did not look like he was joking. "Just don't let anyone find out."

Charles was covered in black lines. He understood what Jack meant: if they killed everyone who saw them, then no one would have seen anything.

Jack said to him seriously, "Hogwarts is dangerous. No one can predict what that Double Socket might do. No matter how unwilling you are, you need a club to save your life."

Charles had already died once, and after finally coming back to life, he had nearly died again. He valued his life dearly, so after hesitating for a long while, he ultimately agreed.

He thought, As long as I don't use it recklessly and only use it to save my life, it should be fine.

Jack did not begin by explaining how to cast the spell. Instead, he went with him to sit beside the cliff. After a moment of silence, he said, "You know, I've seen your memories, but I didn't finish watching them."

Charles nodded.

Jack continued, "The soul, the mind, thoughts, and what you call your worldview—I can't say what their essence is, but I know Dark Magic can affect a person's mind. I just don't know how it does so."

"It's like the beach below us. At first, the water is shallow. As you slowly walk forward, it gradually grows deeper without you noticing. It makes you feel like you can keep going, but in the end, it suddenly becomes an abyss. You step into empty space and fall, never able to surface again."

"Some people have exceptionally firm wills. They prepare themselves from the very beginning, and their hearts can resist this temptation. For example, me."

"Your will..." Jack paused. "All I can say is that when I felt your pain back then, it drove me to flee in panic. I didn't dare go any deeper."

"I believe your will is strong enough to resist the influence of Dark Magic."

Charles said nothing. He simply sat there like a stone man, quietly watching seagulls circle over the sea.

Perhaps because of his transmigration, he always felt that the events of his previous life were both clear and hazy to him. It was deeply contradictory.

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

Jack froze. Like Charles, he became a stone man. Only after a long while did he answer, "The excuse I gave myself at the time was that I wanted to comfort my friend."

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

"Sigh... Looking back now, it seems everyone was at fault."

As he spoke, he rubbed Charles's head and continued, "Child, in the future, if you have something on your mind with your friends or family, say it out loud. Communicate more, understand each other, and be a little more forgiving."

Charles did not understand what had happened in the past, but he understood what the Old Man meant and nodded gently.

"Get up." Jack stood. "Time to start learning. Dark Magic spells, including Avada Kedavra, all have one thing in common: the caster must have an unwavering mind while casting. If you say you're going to kill someone, you must truly kill them. A spell that says one thing but means another will only lightly punch someone."

"In other words..." He searched for a description Charles would understand. "Tsundere people can't use spells like this properly."

This time, Charles understood completely.

"Three days." Jack held up three fingers. "I'll teach you this spell for only three days. If you have talent, you'll be able to grasp the basics within those three days. If you can't master it in three days, you won't learn it even in thirty years."

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

Charles began learning Avada Kedavra.

"Grandpa." When he saw the Old Man demonstrate it, he noticed something was wrong. "Isn't this spell supposed to be green? Why has it turned red?"

Jack said, somewhat surprised, "Weren't you afraid of being sent to Azkaban? So I changed the color."

Charles shook his head. "But it looks almost exactly like the Cruciatus Curse."

Jack thought about it. That was true. The difference between the Killing Curse and the Cruciatus Curse was merely whether you got a single or double room in Azkaban.

"Let me think." Jack began pondering. "Go play for a while."

Charles did not go play. Instead, he went to the kitchen to prepare lunch.

Lunch was simple: traditional fish and chips. If someone had just transmigrated and seen this meal, they definitely would not have been able to tell whether Germany was still bombing Britain.

While eating lunch, Jack said happily, "I've solved the problem. No one will be able to tell it's Avada Kedavra, and they won't mistake it for the Cruciatus Curse."

Charles breathed a sigh of relief, deeply impressed by the Old Man's magical attainments.

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

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

Seeing that Charles was dissatisfied with this and that, Jack said petulantly, "Then should I change it to pink?"

Cold sweat instantly broke out on Charles's forehead. He hurriedly said, "Rainbow is fine. It actually looks pretty good."

"Hmph!" The Old Man continued sulking. "I'm teaching you the pink one!"

"Alright, then." Charles looked dejected. "I'll take your wand and ask all the former headmasters. I'll tell them that the owner of this wand used a pink Avada Kedavra."

Jack was nearly angered to death by him.

In the end, Charles began learning Rainbow Avada Kedavra.
