Although most Wizards in this world do grow more powerful as they age, just like Muggles, they are not without their share of aging effects.
In the world, there are quite a few magical means to ensure one's immortality: Soul Artifacts, the Philosopher's Stone, the Deathly Hallows...
The most reliable among them seems to be the Philosopher's Stone, made famous by Nicolas Flamel, an Alchemy Master born in the 14th century. Using the Philosopher's Stone, he achieved "immortality," living as an ancient relic for more than six hundred years. Every year, someone claims he has actually died, but every once in a while, he publishes a new paper.
Yet, even someone who has lived for hundreds of years cannot stop the aging of his body. He's become so frail that even being hit by a Disarming Spell would leave him bedridden for six months—of course, he won't die, because the Philosopher's Stone still keeps him alive.
William was very curious about this old man, and since Dumbledore is known to be a friend of Nicolas Flamel, he thought about using his connection with Old Bee to contact him. However, all he heard was that Nicolas Flamel was in seclusion. William wasn't in a hurry; after all, this old man has lived for hundreds of years, so it's unlikely he'd suddenly have a change of heart within these two years—right?
Shaking his head to dismiss the idle thoughts, William turned to Newt with a slight smile, "Just some small experiments. The space in your suitcase isn't as stable as you think. I've heard you've used this suitcase for many years; have you ever changed it?"
"I have not—"
Newt replied loudly, not that he wanted to shout, but the runes in William's hand that continued to emit blue light while flying around, accompanied by a "zoom zoom zoom" sound effect, were incredibly noisy.
But William wasn't wrong. Newt cared deeply about emotions, and bringing the little creatures he cared for into a new environment wasn't a simple matter. Therefore, after exhausting the range of the Capacious Extremis, he could only expand more space for each new creature—
"Exactly, the space here has been expanded too many times, and it's like a fifty-year-old woman—too loose."
Space and time: any magic involving these two aspects is extremely advanced. Even a small mistake can affect the world, just like with a Time Turner. And space is the same; though Wizards invented the Capacious Extremis, they know that doing so enlarges a space, but clearly—
There's no one, or no one anymore, who pursues the origins of these Charms.
For instance, why eating a melon could kill someone, leaving not even a ghost—
The Capacious Extremis is the same; its essence is to expand a space, enlarging it within a limited range. Anything has a limit, and Newt's suitcase is no exception—William rarely sees an expanded space larger than this, with the Room of Requirement being the only example.
William once tried to investigate whether the Room of Requirement's essence was an independent space or if it was essentially like Doraemon's Anywhere Door.
The method of verification was simple. William walked back and forth three times in front of the tapestry, wanting a room with golden toilets hanging from all sides, including the ceiling. Thus, upon opening the door, he walked into exactly such a room, with even the toilet seats encrusted with gems—
William thought that no one would be crazy enough to install a toilet on the ceiling, so he confirmed his hypothesis and began studying the golden toilets... No, he studied the Room of Requirement, of course. The gems on the toilet were fake, and William, losing the chance to get rich quickly, had to reluctantly give up.
Then, in 1892, after two and a half years of exploration, he understood the essence of the Room of Requirement and even found a trial left by Rowena Ravenclaw.
However, that trial was meant to test the mind, and at the time, he wasn't confident he could pass it with a 100% chance, so he decided to postpone it. The Room of Requirement wouldn't disappear, he thought, resulting in him leaving, and he ended up wandering for a hundred years. Though much time had passed, for William at that time, it was just as if it had been two months.
So, he wasn't in a hurry to return—
Of course, after going back this time, perhaps he could give it a try to see how difficult the trial left by one of the founders of Hogwarts was.
Watching the blue light rising continuously from his palm, William couldn't help but smile—the continuous runes finally stopped flying around. William gently lowered his opened palm, and the flowing runes began to fall to the ground. Flowers, trees, sunlight, and lush jungles started to grow wildly around them—
"Oh, how did you know I just found a new Tegbo Warthog?"
Newt looked a bit curious. He glanced at the lush jungle around him and then at William's hand hanging by his side. The Tegbo Warthog is a dangerous creature from the Congo Rainforest, known for its tough skin and the ability to turn invisible and sneak up on people, making it impossible to capture or avoid it.
However, because of the valuable fur, the Tegbo Warthog is now a truly endangered species.
Similarly, the one Newt had was saved from the hands of poachers.
"I saw it—"
William didn't continue to tease. He raised his finger towards Newt's eyes. In the next moment, the old man felt a dizzying shift of perspective, the surrounding rainforest disappeared, replaced by darkness and emptiness. As he was about to ask, he heard William say, "Look down—"
Following the advice, Newt lowered his head and saw... everything.
To be precise, it was everything inside the suitcase. The entire space was divided into dozens of squares big and small, each separated by a curtain. He could see the two Nundus he had bred and even the herd of Reem cattle resting on the prairie—
"Wow—"
At over ninety years old, Newt had saved the world, caught Grindelwald several times, and freed small animals countless times under the poachers' noses. What big scenes hadn't he seen? But he had never experienced a scene like this. This God-like perspective felt very satisfying to him—
"I've optimized the space in your suitcase. Now it can accommodate ten times the current number of animals—"
"Better not; if I have so many, Tina might get angry."
In the next moment, Newt blinked and saw the rainforest again. He lifted his thin hand to rub his eyes and sighed softly—he knew his old partner's painstaking intentions to keep him from wandering about, but his lifetime habits couldn't possibly be simply retired like that?
Making him open his eyes just for eating and close them just to sleep was unbearable after three days.
If he hadn't raised a grandson during that time, how could Newt possibly have stayed in that small town in Dorset County for nearly a decade? He would have been bored to death.
"Ha, I've optimized more than just the space—"
William raised an eyebrow and began explaining the modifications he made for Newt, based on the Magic Runes he saw in the Room of Requirement. Using ordinary magic power, everything here could be changed, unlike in the Room of Requirement where he had to use Ancient Magic.
Of course, it wouldn't be as powerful as the Room of Requirement, at most a half-castrated version.
But as long as Newt was in the suitcase, knowing how to use those runes made him like half a God—he could even use that space to hide his private money, and William dared to bet that Tina would never find it, even if she were Tina Holmes it wouldn't happen.
Yet, as William explained, Newt's eyes grew brighter and brighter, and finally, he sincerely thanked William. Originally, he had troubled William to help return the Fire Dragon to Ukraine, but now it seemed he had gained a lot of benefits, unable to think of how to repay him—
"Some Swooping Evil venom? I've always been curious about this creature—"
At this moment, the two had already reached the outermost hybrid zone of the suitcase. Looking at the line of Swooping Evils still hanging on the beams and sleeping, William offered a suggestion while curiously touching the now-bulging two dragons and a dog, "How long was I standing there?"
"Two days, William, you stood there for two and a half days. Today is Christmas—truly, if you hadn't moved in the next two days, I would have taken you back to Hogwarts."
"Two days…"
William wasn't too fazed by Christmas; he just suddenly remembered that he had only assigned Kabuda one day of homework...
No, he must hurry back!
...
Meanwhile, inside the tent of the Starry Sky Club Circus.
The Niffler, who was examining the sparkling emerald offered by Mundungus in its paw, suddenly felt a chill down its spine.
Hiss… a bad premonition.
