After treating Harry's injury, Vison pulled out the dirk cresswell plant, its head freshly plucked.
"This can't go to waste," he murmured.
Harry shook his arm and said, "Mr. Vison, I saw the letter you gave me."
"Of course," Vison replied cheerfully. "Otherwise, you wouldn't be here."
"Then…"
But Vison suddenly interrupted, his tone turning serious. "Actually, Harry, you shouldn't accept invitations from strange wizards so easily. It's very dangerous."
Harry blinked, stunned by the abrupt change in Vison's demeanor. He hadn't expected such a warning. But after a moment, he calmed down.
"But you're not a bad person," Harry said firmly. "You even healed my injury."
Vison smiled thinly, shaking the dirk cresswell root in his hand, bits of dirt still clinging to it.
"Ah, Harry, there are many types of bad people. Some of them smile while they heal you — but only because they have other plans."
Harry shivered and shrank his neck in fright. "What about you, Mr.…?"
Vison raised an eyebrow.
"Your luck's not bad," he said lightly. "I just wanted to scare you."
Harry exhaled deeply in relief.
"Alright, enough small talk. Let's get down to business." Vison handed Harry the larger part of the dirk cresswell plant.
Harry took it, blinking in confusion.
"Your next task is to learn how to make a bottle of essence of murtlap from this plant," Vison explained.
Of course, this wasn't Vison's real purpose.
His true goal was to have Harry spend time in close proximity to the Tree of Wisdom. That might be the key to its unusual growth progress.
Vison waved his wand, and a table flew out from the corner of the shed. On it sat a battered old cauldron, along with ingredients for brewing essence of murtlap — pure spring water, ground dirk cresswell, unicorn tail hair tips…
"Oh, right, and this."
Vison handed Harry a stick.
"Although this wand might not suit you perfectly, we don't have a better option right now."
Harry's eyes sparkled as he accepted it. He had seen Vison perform amazing magic with such a stick before. Now, excitement made him speechless.
"I don't recommend you try spellcasting yet," Vison said. "Your magic is still immature. But potions? That's safe enough."
Harry nodded eagerly. He didn't know why Vison was willing to teach him, but he wasn't about to refuse.
No matter the reason, he was desperate to get closer to the world of magic.
So, under Vison's patient guidance, Harry began his first potion-brewing session — full of excitement and hope.
...
As it turned out, potion-making was far less thrilling than casting spells. At least, that's what Harry felt.
After failing countless times to produce a usable essence of murtlap, his enthusiasm started to fade.
"Mr. Vison… I think this might be a little too hard," Harry said cautiously.
Vison pinched the bridge of his nose, exasperated.
This kid really wasn't cut out for potion-making.
Look at that! For the third time, Harry had stirred the potion in the wrong direction. Three times!
"Alright, Harry," Vison sighed, covering his forehead. "Let's try again."
Harry wiped sweat from his brow and glanced outside the greenhouse.
"Mr., I think I should go back. It's probably getting dark."
Vison raised an eyebrow and pulled out an old but finely crafted pocket watch. He glanced at it.
"Hmm. Indeed, it's already four o'clock."
The time inside the plantation matched the outside world — the sky here mirrored the real sky.
Vison tucked the watch back into his pocket and gave Harry a faint smile.
"Since that's the case, let's stop for today. Come back at the same time tomorrow."
"Do I have to come back?" Harry asked, blinking.
Vison patted his shoulder.
"Potion practice requires perseverance. Patience is even more important than magic."
Harry frowned slightly, something clicking in his mind.
"Isn't this stuff I'm supposed to learn only after starting at Hogwarts?"
Vison chuckled.
"Oh, Harry, this is just kindergarten material."
"Kindergarten?" Harry's eyes widened. "Hogwarts has a kindergarten?"
"Of course not," Vison said with a wink. "But you've met me now. It's always good to pick up some skills early, right?"
Harry opened his mouth, ready to argue, but then shut it.
"Alright," he shrugged with a resigned smile. "See you tomorrow."
Vison nodded and waved his wand.
A gust of wind swept through, and the scattered ingredients neatly floated back to their proper places on the table.
While tidying up, Vison turned and called out,
"Eldra, how is your growth progressing?"
A faint voice returned in his mind:
[Status: Growing (2%)]
Vison's heart leapt with joy.
As he had suspected!
For a whole week before Harry's arrival, the Tree of Wisdom had stayed at 1% growth. But now, after just one afternoon with Harry, it had ticked up by another point.
Vison was nearly certain — this was no coincidence. Harry Potter was the cause.
As he walked Harry to the door, Vison reached into his pocket and pulled out a small green object, roughly half the size of a fist. He handed it to Harry.
Harry turned it over in his hands, frowning in confusion.
"What's this?"
Vison smiled mysteriously.
"This is Chinese biting cabbage."
"Chinese biting cabbage?" Harry instinctively leaned back, shifting the object away from his face. "That… doesn't sound very safe."
As if responding to Harry's movement, the cabbage twisted in his grip, revealing a mouth full of sharp little teeth — pointed directly at Harry.
"Ah!"
Startled, Harry yelped and threw the plant into the air.
Vison calmly flicked his wand. A soft blue shimmer appeared, catching the flying cabbage and freezing it midair.
"It doesn't like being tossed around," Vison said with a chuckle. "Don't let its appearance scare you — it's actually quite safe."
The cabbage twisted and writhed against the levitation spell, trying to free itself. But Vison's magic held firm, unyielding as a mountain.
Slowly, Vison floated the plant back toward Harry.
"Remember, don't be afraid. When you show calmness, it will calm down too. Once it recognizes your scent, it won't attack."
Harry hesitated, swallowing nervously. But finally, he reached out and cautiously took the cabbage from the air.
To his surprise, it settled quietly in his palm this time.
Its small teeth were still visible, but it showed no sign of aggression.
"See?" Vison smiled warmly. "It's already starting to like you."
In truth, ordinary biting cabbages weren't usually this docile.
But these particular plants had been "mutated" by Vison's own methods.
While they had lost some of their natural aggressiveness, they had gained obedience — they would only bite when commanded, rather than attacking indiscriminately.
Harry stared at the plant in wonder, a small smile forming on his lips.
Vison, watching silently, couldn't help but feel a spark of satisfaction.
Yes… things were progressing just as he hoped.
