It had not been long since Lewis learned the seventh-ring spell.
Except for Shirella, this was the first time the girls had seen Lewis use [Portal], and each of them was filled with curiosity.
They had heard of Apparition, used Floo Powder, and even experienced Portkeys.
But none of them had ever seen such a convenient spatial spell.
Led by Lewis and Shirella, the six of them stepped through the portal together and entered the tower.
The girls were quite curious about Lewis's home.
They had always wanted to see the place where Lewis and Shirella lived.
However, their most pressing concern today was the tower's true secret.
Filled with curiosity and a faint sense of inexplicable excitement, they followed Lewis to the underground section of the tower.
Lewis's workshop, library, and storage rooms were all located here.
The moment they saw the scene before them, Zhang Qiu, Luna, and Penelope's understanding of Lewis was completely overturned.
They had all known that Lewis had grown wealthy after his first year.
But they had never imagined that Lewis possessed so much wealth and resources!
There was even more here than in many pure-blood families.
For young wizards from ordinary families, even a small portion of the things inside this tower might require them to work hard for their entire lives to obtain.
A library comparable to Hogwarts' own.
A treasury filled to the brim with gold and Galleons.
A storage room packed with all kinds of precious materials.
A treasure vault containing Lewis's various creations, along with countless alchemical products and potions.
A workshop surrounded by all kinds of precious experimental equipment, both familiar and unfamiliar.
Not to mention the greenhouse filled with all kinds of magical plants.
And an entire vast forest.
Lewis had already begun purchasing magical creatures and raising them here.
Almost every place they visited left the girls utterly amazed.
Finally, Lewis led the thoroughly astonished young witches back to the first-floor hall.
With a wave of his wand, chilled soda and sweet, delicious macarons appeared on the table.
"Eat," he said.
"Afterward, I have some gifts to give you."
Once the girls had calmed down somewhat, Lewis continued.
"First, the gift I want to give you is—"
Seeing the interested looks on their faces, Lewis pulled Hermione's arm toward him and began drawing on the back of her hand with his wand.
Soon, a magical tattoo representing [Intellect] appeared on the back of her hand.
Hermione had conducted a great deal of research into the history of the previous wizarding war because she planned to join the Ministry of Magic after graduation.
"Isn't this somewhat similar to the Dark Mark used by the Death Eaters under the Dark Lord?" Shirella suddenly asked.
"You're right."
As Lewis finished inscribing the pattern on Hermione's hand, he explained, "I did take inspiration from the Dark Mark, but I also incorporated magical tattooing techniques into it. Essentially, it permanently leaves an enchantment from alchemy on the skin through tattooing, thereby granting the bearer new magical abilities."
"This mark has the same sensing function as the Dark Mark. But it can do much more. For example, I've bound the [Mansion] spell to this mark. As long as you inject magic power into the tattoo, you can summon this tower."
"Of course, it also serves as an identification mark. With this tattoo, you'll be able to use most of the tower's functions, such as opening the doors to various storage rooms. Your specific permissions can be updated at any time."
After her tattoo was completed, Penelope examined the back of her hand and suddenly said, "But this really does resemble the Dark Mark. Having this makes me feel like I've joined some secret organization—such as 'Lewis Green and His Girlfriends'?"
"What kind of name is that?" Lewis complained.
After pondering for a moment, he came up with an idea.
"I think this mark should be called the 'Mark of Intellect,' while the organization should be called the 'Genius Club.'"
Hermione gently touched the mark and said, "It doesn't look evil. I like the name Intellect, but 'Genius Club' sounds a little..."
Even someone as straightforward as her couldn't help but blush at the name.
Once everyone had received the Mark of Intellect tattoo, Lewis waved his wand again.
Several bottles of potions appeared.
These were permanent attribute potions.
"These potions can comprehensively improve your various abilities, including strength, agility, endurance, intelligence, perception, and charisma. Each color represents a different attribute. After drinking one, you need to wait for a certain amount of time before drinking another."
Then Lewis advised them, "Personally, I recommend that you drink the [Permanent Intelligence Potion] first. I believe that after taking it, passing your final examinations will be a piece of cake. Even Penelope's N.E.W.T.s won't be a problem."
Lewis smiled as he distributed the potions to the four girls other than Shirella.
"No wonder you learned so quickly after returning from Christmas," Penelope said in sudden realization. "So you secretly drank something this good. You have to tell me about it later."
With that, she immediately drank the Intelligence Potion.
With Shirella as an example, she trusted Lewis completely.
Hermione desperately recalled everything she had read about potions.
She had indeed seen descriptions of potions similar to "intelligence-enhancing potions" in some books, but their effects were generally temporary.
Apparently, none of the books she had read described a potion with a permanent effect.
But that didn't stop her from drinking it.
Zhang Qiu's talent was relatively average among the group. Compared with the others, she needed these potions even more.
As for Luna, her curiosity about the potion itself far exceeded her desire to experience its effects.
She shook the little bottle, then drank the potion in tiny sips. Every now and then, she smacked her lips, seemingly savoring the taste of the potion.
Feeling the surge in mental ability after drinking the potion, the girls finally understood why the organization was called the "Genius Club."
With permanent attribute-enhancing potions like these, even ordinary people could be artificially turned into geniuses.
"Now, take out your wands. I have a third gift for you."
Lewis continued.
Shirella had now also switched to the Arcane Sword 310. Janna and Tonks had also taken an interest in Lewis's wand and protective equipment set.
This had given Lewis the idea of producing a batch of goblin-silver wands and protective bracers.
Now that the girls had come over, it was the perfect opportunity to customize a set for each of them as a welcome gift.
In fact, Lewis had been purchasing goblin silver all along to create various magical items. Since the girls were here, he might as well customize a set for them as a gift.
After all, the mithril wand set had many advantages. Not only did it provide a greater boost to spellcasting ability, it also had a magic-storage function, could prevent the [Disarming Charm] from working, and left no trace.
But what Lewis hadn't expected was that, in Zhang Qiu, Hermione, and Penelope's eyes, the most interesting item wasn't the wand at all.
It was the wrist-mounted bracer.
They all thought the ingenious device was both cool and creative.
Assassin's Creed had managed to attract so many fans with its hidden blade for a reason.
For Luna, however, the most precious things seemed to be the empty potion bottles left behind after the other four had finished drinking their potions—their wooden corks.
Under everyone's somewhat puzzled gazes, she casually picked out two of them, threaded them onto the butterbeer-cork necklace around her neck, and wore them proudly.
"There's one more extremely important matter."
Lewis's expression turned serious as he warned them, "To ensure that the secrets here aren't leaked, you must learn [Occlumency], [Mind Expansion], [Mechanized Mind], and other spells that can defend against mental detection as soon as possible. This is your most urgent task."
"Until then, don't get too close to Dumbledore or Snape. They're both extremely skilled in this area."
"Especially Dumbledore. He can even use [Legilimency] on people without a spell or wand."
"When it comes to this kind of magic, I recommend learning the simplest [Mechanized Mind] first. This is only a second-ring spell. Once activated, it makes your thoughts cold and rational, effectively preventing others from peering into your mind."
As he said this, Lewis's expression became particularly solemn.
Although the Dumbledore in the girls' minds was clearly someone they couldn't associate with evil, the dangers of being subjected to Legilimency still made them take the warning seriously.
After all, Lewis's tower contained too many secrets, and the fewer people who knew about many of them, the better.
"Finally, there's my current work."
As Lewis spoke, he placed a stack of books in front of the girls.
It was a complete set of Standard Spells, along with The Beginner's Guide to Transfiguration, Intermediate Transfiguration, and Advanced Transfiguration.
"I'm currently focusing on incorporating our existing spell system into the theoretical framework of Arcane Magic. I've already completed the adaptations of the Charms and Transfiguration textbooks. If you're interested, you can take a look. Not only will they deepen your understanding of magic, they'll also be very helpful for learning Arcane Magic."
The girls took the newly revised textbooks from Lewis and began flipping through them.
Lewis continued, "In the days to come, I'll adapt all the most mainstream and commonly used magical books. The results will all be stored in the tower, and you can come and read them whenever you want. If you need a copy, you can reproduce one yourself. I remember there's a printer in the study enchanted with [Scribe] and [Scholar's Touch]."
"Besides that, I'll eventually record all the Arcane Magic I know in book form. I'll call it the Book of Ten Thousand Spells, so it'll be convenient for you to study on your own. But keep these materials to yourselves. Absolutely do not reveal them to anyone else."
The girls chatted with Lewis for a long time.
By the time the six of them returned to Hogwarts from the tower, the sky was already beginning to brighten.
Everyone hurried back toward their respective dormitories.
Hermione was the only Gryffindor among them, so she had to return alone.
Lewis, meanwhile, returned to the Ravenclaw common room with the other four girls before waving goodbye.
Although Lewis would have to begin another day of work soon, his mood was surprisingly relaxed despite having stayed up all night.
He had finally brought several of the girls into his cause.
In the future, these talented witches would become another driving force behind his plans.
