Return of Salazar Slytherin

149- Ravenclaw is very envious

"Then, can this spell be used to preserve various potion ingredients?"

Daphne was the first to think of the Stasis Field's application in the field of potion-making.

Most potion ingredients lose their potency as time passes. Daphne imagined that if they could add a Stasis Field to potion storage cabinets, the ingredients could stay as fresh as when they were first harvested.

"In theory, yes," Rhys shook his head.

Most potion ingredients require some form of preprocessing after being harvested. Once they've been treated, their shelf life can be greatly extended. Many materials can last for one or two years without issue, while the Stasis Field only lasts for hours.

Attempting to use the Stasis Field for long-term preservation is impractical.

Even Rhys, the spell's inventor, couldn't make the spell last for years. As time goes on, the time differential between the space inside and outside the spell increases, greatly accelerating the spell's magical consumption.

"Then could it be used for healing? For instance, keeping someone frozen at the moment just before death?" Astoria was more curious about whether the spell had medical applications.

Rhys shook his head again. Encompassing an entire person would require a much larger spell field, which would significantly increase the difficulty of casting the spell.

However, there was indeed potential for medical applications.

Rhys had heard that Muggles sometimes use organ transplants to treat certain diseases. His spell could certainly be useful in this regard.

It could genuinely extend the transportation time for organs.

But the issue is that the magical world has its own medical system, and organ transplants are extremely rare.

Most conditions that would require organ replacement in the Muggle world can be solved with potions or alchemy here.

For example, if an Auror loses an eye in battle, the Ministry of Magic can provide them with an alchemical prosthetic eye.

So, the Stasis Field has almost no practical use in the medical field either. As things stand, until the spell undergoes a major breakthrough, its most practical use remains keeping food warm in lunchboxes.

After answering the two girls' questions, Rhys began explaining the key points of casting the Stasis Field spell.

After listening to Rhys' "lesson," Daphne squinted, thinking for a moment before realizing something: "Rhys, the spell you used to preserve ice cream before, was that this one?"

Rhys: '...'

Daphne, were you not paying attention?

You must have been distracted, right?!

"No, that was just an ordinary freezing spell. Ice cream doesn't change its texture too much after freezing." Rhys gave a brief explanation, then urged Daphne to start trying to cast the Stasis Field.

To make it easier to observe whether the spell worked, Rhys brought out a small box.

The top of the box had a small hole, and a thin wisp of smoke slowly drifted out, giving off a faint scent.

If Daphne's spell was successful, the smoke would stop because the time inside the smoke box would have been "frozen."

Daphne tried several times, but the spell was incredibly difficult. None of her attempts were successful.

After practicing for a while, Daphne gradually found the trick to it and was able to momentarily freeze time in an area the size of a coin.

"Not bad," Rhys nodded with a smile.

Daphne's mastery of the spell was progressing as fast as that of Gryffindor's pace, which impressed him.

Seeing this, Astoria, standing nearby, was eager to give it a try. Noticing her enthusiasm, Rhys slid the smoke box over to her, indicating she could have a go as well.

Astoria followed Rhys' instructions, recited the incantation, and made the corresponding hand movements. The next moment, the thin column of smoke above the box abruptly stopped for an instant.

Rhys: !

Daphne: ?!

Both were shocked by Astoria's progress.

Did she succeed on her first try?

Was this pure talent or just luck?

But as Astoria continued to practice, she demonstrated that it wasn't luck. She could indeed cast the spell effectively.

Although the time freeze lasted only for a brief moment, it was a breakthrough from nothing. Moving forward, she just needed to practice controlling her magical output to significantly extend the spell's duration.

'Amazing!' Rhys thought to himself. If they weren't in the library where silence was required, he would have applauded her on the spot.

Successfully casting the Stasis Field spell on the first try? That kind of talent was truly remarkable.

Daphne pressed her lips together, suddenly feeling a sense of crisis: Was her sister's talent far greater than her own? This thought unsettled her.

She was afraid.

Afraid that Rhys would no longer teach her, and terrified that everything she currently enjoyed would be taken away by her sister.

'But I'm healthier than her. No matter how talented she is, if her illness can't be cured, how long can she even live?' This dark thought flashed through Daphne's mind, and she was immediately horrified by her own thinking.

How could she have such a thought!

Daphne felt ashamed of herself.

She lowered her head, trying to hide her eyes from both Astoria and Rhys.

Having confirmed that Astoria could successfully cast the Stasis Field spell, Rhys decided to take her on as a student—such a gifted child, keeping her in school to just learn simple spells like the Cutting Curse or Levitation Charm would be a waste of her potential.

If she could control her magic as well as her sister, Astoria might be the most naturally gifted witch Rhys had ever encountered.

"Come on, I'll take you somewhere," Rhys gestured for Astoria to follow him to a secret location.

"Where are we going?" Astoria stood up, her eyes shining with curiosity.

"A place only true Slytherins can enter," Rhys said, standing up.

He then noticed that Daphne had her head lowered, seemingly preoccupied with something.

"Hey, get up, we're going to the special classroom," Rhys called out to Daphne.

Daphne raised her head in surprise and asked, "I can go too?"

Rhys paused, then asked in return, "Huh? Do you have something else to do?"

Suddenly, he realized what was going on and couldn't help but laugh to himself.

Did this child think she was being "eliminated"?

While his energy was limited, managing two students was more than feasible.

There was never a limit on the number of heirs!

Ravenclaw and Gryffindor only had one chosen heir each, not because they could only pick one, but because only one was suitable.

He himself had chosen both Barrow and Adrian, after all. Although one of them often frustrated him, both had access to the Chamber of Secrets and were qualified to be the Head of Slytherin House.

Realizing that she still qualified to be taught by Rhys, Daphne immediately brightened up. She stood up from her chair, grabbed her sister's hand, and eagerly headed toward the Chamber of Secrets, nearly rushing as if she couldn't wait to get there.

After Daphne and Astoria left, Rhys felt a gaze fall upon him.

He turned to see Ravenclaw's projection standing in the corner, watching him.

Rhys could sense a hint of envy in her gaze.
