Harry Potter and the Great Old Ones

After Tiera showed Hermione the instability of the "divine magic stone".

Hermione stopped asking questions and fell into deep shock and contemplation.

After an unknown amount of time, Horace Slughorn seemed to have finally reached the final stage of brewing. Horace Slughorn took out his wand and waved lightly at the liquid suspended in the air——

The liquid changed color instantly, from mixed silver-gray to bright red, and then to translucent orange-red.

After Horace Slughorn saw the change in the solution, he quickly took out a test tube from his arms, waved his wand, and filled the test tube with the translucent orange-red liquid.

"Ah, Tiera." Horace Slughorn, who had finished refining Alpha-36 solvent, finally noticed Tiera and Hermione who had entered the Room of Requirement again, "Look."

As he spoke, Horace Slughorn shook the test tube containing the translucent orange-red liquid in his hand.

"Excellent, congratulations, Professor Slughorn." Tiera clapped her hands softly and said, then turned sideways and pointed at Hermione standing behind her, "Hermione Granger, I believe you

There must be an impression."

"Ah, yes, yes, Miss Granger," said Horace Slughorn, smiling.

"That's right, I think Hermione's calculation level is already capable of some simple calculations in the process of refining the magic stone." Tiera said with a smile, "And Hermione also plans to participate in the general admissions of the Magic University in a few years.

For the exam, I think maybe you can take her with you... um... let her help you with it."

"What? Another, another, another, another, another?" Horace Slughorn asked in shock.

"Tiera... look, I, I will also tutor Harry in Occlumency... Hermione, although Hermione is excellent, but... but... she is still a long way from mastering it.

The distance...maybe it will make it a lot easier for me in the later stage, but...but it will require me to expend a lot of energy in the early stage...and what if there is something wrong with her calculations..."

Although Horace Slughorn did not finish what he said, both Tiera and Hermione understood what Horace Slughorn meant next.

"It doesn't matter." Tiera said with a smile, "Just assign tasks to Hermione and let her watch your refining process. Just leave her calculations to me."

Valley falls

"But Tiera... I'm really pressed for time..." Horace Slughorn said again.

"Okay, okay." Tiera seemed to have given in, "Well... you can probably do something about Harry. Anyway, with me watching, it's unlikely that anything big will happen to Harry...

Or you could look at the professors in our school who are also good at Occlumency, and you could ask him to help teach them."

"Okay, okay, that's no problem." Horace Slughorn breathed a sigh of relief as if he had received an amnesty.

"Then Professor Slughorn, I'll leave it to you." Tiera said with a smile.

"No problem, no problem, Miss Granger is very talented and gifted." Horace Slughorn rubbed his hands and laughed, like a happy big seal.

"Then Hermione will be left to you." Tiera said with a smile, "You first take her around our laboratory, introduce the general process, and some basic principles... I have already explained the calculation process above.

She has been trained during the semester, so you can just assign her the task."

"Okay, okay," said Horace Slughorn.

"What about you?" Horace Slughorn asked strangely, "What are you doing?"

"Oh... there is a visitor coming to Hogwarts, and Dumbledore needs my help to receive him," Tiera said.

"Don't you have several Tieras?"

Horace Slughorn asked strangely.

"This Tiera must be received as a student Tiera." Tiera said with a smile.

Thirty minutes ago, Sirius Black walked out of the fireplace of the Three Broomsticks Tavern in Hogsmeade Village and made a request to the doorman of Hogwarts to see Dumbledore.
