Hagrid is Very Serious

"This spell is called [Mage Hand]," Mu En said slowly, searching the desk and finally finding a few parchment manuscripts.

"Mage Hand?" Harry murmured.

"That's right. It creates a ghostly hand that can help the caster manipulate objects and interact with them."

As he spoke, a slightly transparent, fluorescent blue palm appeared before Harry's eyes. The palm was extremely flexible, gently tapping the bookshelf before pulling out a book.

"It's a basic spell, and many beginner wizards choose it as the first spell they learn," Mu En explained.

"Tell me about this spell, from a casting perspective." As he spoke, the fluorescent blue Mage Hand floated in front of Harry.

Harry thought for a moment, then shook hands with the Mage Hand.

This fluorescent blue hand interacted with reality, having form. When he grasped it, it felt a bit cold.

"Shape, color, and… interaction with reality!!" Harry exclaimed, his eyes growing brighter. He muttered, "No… that's not right. The core is interfering with reality, interacting with the real world!

From a spellcasting logic standpoint, both the hand's shape and its color are just frameworks designed to better help the wizard influence reality!"

After speaking, Harry looked up, watching Mu En with a hint of nervousness.

"Interesting. What you've said is basically correct. The fundamental logic of Mage Hand is to interfere with reality."

As he spoke, the Mage Hand before Harry began to twist and writhe, changing its form.

"Whether it's shape or color, they are merely frameworks of abstract concepts set to make it easier for beginners to anchor to reality."

Harry watched in amazement as the Mage Hand before him, like clay, turned into a knife, then a sword, then a rope.

"At this stage, you can already use Mage Hand as an offensive spell. Especially if we discard its color, it can easily achieve remarkable effects."

As he spoke, the constantly changing Mage Hand before Harry gradually became transparent. Immediately after, he felt a slight stinging sensation in his forearm.

He looked closely and saw that a patch of skin on his forearm seemed to be being pricked by an invisible small knife.

Harry couldn't help but shudder at the thought. He wondered how terrifying it would be to suddenly attack someone like this.

"So that's how it is!" he nodded.

Mu En nodded. "Lesser wizards treat Mage Hand as a functional magic; excellent wizards treat it as a combat magic that can achieve remarkable effects.

But do you remember what I said at the beginning?"

"This magic is used for brain development work," Harry replied instantly.

"Correct answer!" Mu En snapped his fingers, saying with satisfaction, "Once this magic is freed from the constraints of color and shape, the demand on our cognitive coordination abilities will increase dramatically.

Therefore, for top-tier wizards, Mage Hand is a rare spell for exercising their brains!

Learn this spell before your birthday. Before school starts, be able to control two or more Mage Hands to work synchronously.

Any questions?"

Harry nodded, full of spirit, "No questions."

There was still a week until his birthday. Although time was a bit tight, Harry felt it was not an impossible task.

"Very good, very spirited!!" Mu En praised. "And these two books on Ancient Runes are also your homework for this holiday."

"Huh?!" Harry stared blankly as the two thick books floated towards him, catching them dazedly.

"Keep at it!" Mu En said with a smile, then placed the two parchments from earlier onto the books Harry was holding.

"This is the casting method and thought process for Mage Hand. Feel free to ask me if you don't understand anything."

A week passed quickly. This was one of the rare weeks Harry felt utterly exhausted since arriving at Moonlight Castle.

Unlike previous exhaustion, the Mage Hand spell had been pushing his casting limits almost every day, even draining his energy and spirit.

However, after a week of torment, he had finally become proficient with the spell.

He could now manifest a small blue hand to help him retrieve things that weren't too heavy.

But he couldn't yet use Mage Hand for precise actions like writing.

Manifesting two hands always caused the magic to collapse.

Harry had personally witnessed Uncle Mu En sitting on the sofa, with over a dozen Mage Hands working simultaneously on different subjects.

The spell precision, information processing ability, and magic control behind it almost made Harry feel suffocated.

It was too terrifying!!

One morning, after breakfast and cleaning up the dining table, Harry was about to head to an empty room on the second floor for his physical training when Mu En suddenly called out to him.

"Harry, go change your clothes. No practice today, we have a guest," Mu En said.

"A guest? Is it one of your friends, Uncle Mu En?" Harry asked, somewhat surprised. He had been here for so long and had never seen any guests visit.

"No, I… don't have many friends here," Mu En shook his head.

Just then, there was a violent knocking sound on the door.

Harry frowned and thought to himself, "So it's a troublesome guest!!"

With that, he went to open the door.

The enormous figure stood blocking the doorway, his bushy beard and fleshy face giving him an imposing aura.

Harry flinched, stepping back quickly, his breathing growing heavy.

The man's physique was simply too massive, his presence overwhelming.

He eyed the figure outside warily, his hand already reaching his waist, gripping the hilt of the Blue Steel Longsword within its pouch.

Then, under Harry's watchful gaze, the tall figure did his best to bend his eyebrows and smile kindly. "Oh, hello there. I'm Rubeus Hagrid. From Hogwarts... uh, the gamekeeper responsible for taking Harry to Diagon Alley."

He paused, then suddenly changed the subject. "Are you Harry?!"

"Harry, you don't need to be so on guard. He's from Hogwarts," Mu En said, finally shifting his rear off the red sofa. "Quick, invite him in to sit down."

At this moment, Hagrid also noticed the figure inside the house. He called out in confusion, "Dursley?! Are you Dursley??"

Mu En opened his mouth, glanced at Harry, then looked at Hagrid again.

This man... isn't faking it?

Fine, Mu En had to admit, Hagrid's statement had rendered him speechless.

Mu En waved his hand. "I was just saying old Dumbledore has gone senile, he didn't mention me to you?!"

"Hey! Don't talk about Dumbledore like that!" Hagrid suddenly bristled, clearly quite angered, but the next moment, he suddenly remembered.

Dumbledore had told him that Harry Potter was currently with a very powerful wizard.

"You're the wizard Headmaster Dumbledore mentioned?" Hagrid realized, then said sternly:

"Dumbledore isn't senile, I'm the one who forgot!!"

Mu En heard this and was stunned for a long moment. He carefully looked Hagrid up and down, then said helplessly, "Alright, Dumbledore isn't senile, it's all your fault."

"That's right! Don't say such hurtful things anymore!" Hagrid said very seriously.
