"You mean Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw might still be living in the Room of Requirement?" Hermione almost screamed.

"You mean Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw might still be living in the Room of Requirement?" Hermione shouted again.

"I heard you when you called it for the first time." Tiera rubbed her ears helplessly.

Even as smart as Hermione, when receiving such shocking news, it was difficult to keep calm, and instead shouted out.

"It's just possible." Tiera said lightly, "Even Slytherin himself is not very sure, he just said that he still feels a familiar atmosphere lingering in this castle."

"Then why didn't he go after them?" Hermione asked. "I mean, if they were really in the Room of Requirement, wouldn't Slytherin just go in and look for them?"

"What's wrong?" Tiera asked.

By this time they were already standing opposite the giant tapestry of Troll Sticks Beating Barnabas.

"I hope to have a room that meets my needs for refining the Philosopher's Stone."

"I hope to have a room that meets my needs for refining the Philosopher's Stone."

"I hope to have a room that meets my needs for refining the Philosopher's Stone."

Tiera recited it three times aloud, and at the same time the thoughts in her mind concentrated and radiated outward.

Soon, the wall directly opposite Tiera and Hermione changed.

Gradually, magical lines and patterns appeared, which together outlined a very huge bronze gate.

Tiye stretched his hand to the handle of the bronze door and pushed it.

"crunch-"

The bronze door slowly opened, revealing the vast and brand-new laboratory inside.

Sets of clean and tidy glassware are placed on test bench after test bench in a predetermined order.

On the floor in the center of the room is carved a variety of twisted, bright lines, textures and ravines.

"Are we going to wait here for Professor Slughorn?" Hermione asked hesitantly, seeing that there was no one in the Room of Requirement.

"No, no." After that, Tiera pulled Hermione out again, and closed the door of the Room of Requirement.

"Horace Slughorn has already started his work here," Tiera said.

"What?" Hermione asked in confusion.

Tiera smiled silently.

"I would like to have a time duration of 7,874,651,610 cycles of radiation corresponding to the transition between the two hyperfine energy levels of the atomic ground state of cesium-133, and the acceleration of gravity is 3.70 m/sq. The room temperature is always maintained at twelve degrees Celsius, and the room that Horace Slughorn walked into at seven thirty-seven this morning." Gu Jue

The bronze door embedded in the wall began to dim, as if retreating into a rough mural.

The patterns on the wall squirm again, beginning to produce mysterious changes.

Soon, the pattern on the wall was fixed and turned into a bronze gate again.

Tiera smiled, stretched out her hand, grabbed the doorknob, and pushed hard—

"crunch-"

The bronze door was pushed open, revealing the empty space inside. There were only a few test benches in the center of the room, and a room with some runes inscribed.

Beside the test stand, Horace Slughorn was holding out his seal belly, stirring something carefully on the test stand.

His expression was so focused that even the opening of the door to the Room of Requirement and the presence of Tiera and Hermione didn't bother him.

"So you see..." said Tiera, walked in, and jumped slightly.

Tiera jumped high easily.

"The House of Requirement is the most perfect place to refine the magic stone." Tiera slowly fell back to the ground, "Of course, it's not the only place, the alchemy hut built by Mr. Nicolemeier can also achieve a similar effect. ...but it's a lot easier to operate than a Room of Requirement lock."

"It's amazing!" Hermione exclaimed, and she wanted to step inside-

"Here, take this, stay on your head." Tiera saw Hermione want to step into the Room of Requirement, pushed Hermione outside, and then reached out and waved a few times in the air —

A shiny crown appeared out of thin air in Tiera's hand.

"Put this on, it can effectively isolate your thoughts, and you can't control your thoughts very well now." Tiera explained, "Let's use an analogy, the temperature inside this room of responsiveness is now Twelve degrees Celsius, if you go in and feel too cold, and the thought of 'If only this room could be warmed up a little bit' flashed in your head a few times, then the temperature in this room will instantly rise to Twenty-six degrees is the most comfortable degree for humans, and this time... if we are conducting an experiment that requires precise control, then our experiment may immediately fail."

"Oh, oh, ok, ok." Hermione said, taking the crown from Tiera's hand, putting it on her head, and pressing it down with both hands, letting the The crown of her head was firmly stuck on her shaggy hair.

"Okay, let's go, let's go in." After seeing Hermione put on the crown, Tiera took Hermione one step into the Room of Requirement.

"Gu... gu... sure enough, it's really cold," said Hermione.

"Of course, there are only twelve degrees here." Tiera said with a chuckle, "and the movements are a little smaller here, after all, the acceleration of gravity here is only 3.7."

"Now what Slughorn is cooking is the Sage's Stone, UU reading www.uukanshu.com or the Alpha-36 solvent in the process of refining the Philosopher's Stone, the main material of which is dragon blood... To be precise Eighty percent of the dragon's blood of the Hungarian tree peak dragon, and thirteen percent of the dragon's blood of the Venomous dragon and seven percent of the dragon's blood of the Constantinople Bonebreaker, stirred in a lead cauldron and bronze The stick was stirred continuously for 30 minutes at twelve degrees, and then a specific dose of Gogo tree bark, stinging flower petals and a stamen, and tranquility grass, flamingo feathers, silver soil, knitting were added in sequence. Grass...wait, wait..."

"It will be a long time before Professor Slughorn completes the experiment of the boiling stage. Let me tell you the basic principles of alchemy first."

"Let's start the experiment directly!" Hermione said nonchalantly, "I have finished reading Introduction to Alchemy."

"Hermione, reading Introduction to Alchemy and understanding Introduction to Alchemy are not the same thing," Tiera said slightly sternly.
