Harry Potter and the Old Ones

"Then they'll be left to you." After everyone crossed the aperture and arrived at Hogwarts, Tiera said to another Tiera who came out of Hogwarts.

"Of course, Tiera-san." Another Tiera——

He was wearing a golden-red papal robe, a pair of gold-rimmed glasses on his face, and a dark red wizard's hat on his head.

"Thank you for your hard work, Tiera-san." Tiera said.

"Hey, I'll have to work hard for you next, Professor Tiela." Classmate Tiela said.

"It's not hard." Professor Tiela pretended to shake hands with classmate Tiela.

"Then goodbye, Harry, goodbye, Ron, goodbye, Ginny." Classmate Tiera said, stepping back and creating a human-shaped hole in the air.

As Tiera disappeared, the hole in the air also disappeared.

"Go in by yourselves." Professor Tiera said with a smile, "I still have to wait here..."

Before Tiera could finish speaking, another door of light opened in front of him——

First, several suitcases flew out, flying towards Gryffindor Tower as nimbly as a bird, and then Tiera, who had just disappeared, walked out of the light door with Hermione.

"Harry! Ron!"

As soon as Hermione walked out of the light door, she gave Harry and Ron a hug.

"Okay, long time no see, Hermione." Ron got out of Hermione's arms with some trepidation.

"Long time no see Ron." Hermione let go of Ron and Harry carelessly.

"Well...Long time no see, Hermione." Harry said, "How was your summer vacation?"

"Great!" Hermione said, "I..."

Hermione hesitated and looked at Tiera——

The student Tiera disappeared directly to pick up other students from Dumbledore's Army, leaving only the professor Tiera standing at the door.

"I finished the exercise book Tiera gave me this summer." Hermione saw the professor Tiera nodded and continued, "I also successfully mastered several black...several magical magics. "

"What?" Harry asked in surprise, "But Hermione, we are not allowed to use magic outside of school! How do you practice?"

"I'm helping." Professor Tiera said in a gentle voice.

"Ah?" Harry said in surprise, "Why don't you help me practice magic?"

"Have you finished all the calculation problems I left for you?" Tiera asked, "Have you learned the magic configuration I taught you last semester?"

"Or take a step back." Tiera continued to ask aggressively, "Did you even open the exercise book I gave you during the summer vacation?"

"You still need me to help you practice magic like this?" Tiera shook her head and sighed, "Should I help you practice magic or help you collect corpses?"

Harry bowed his head in embarrassment and remained silent.

"Harry, magic is not a child's play..." Tiera paused, "To be precise, you will be in my class from now on..."

"Ah ha, Neville, long time no see." Tiera was interrupted mid-sentence by a light door that suddenly opened.

"It's been a long time...well...didn't we just meet?" Neville said strangely, "You saw Tiera as a student, and now you see Tiera as a professor."

"Is...is there any difference...?" Neville asked.

"I can deduct points now." Tiera said with a wicked smile.

"Well..." Neville was silent for a moment.

"Where did I just say that?"

"Child's play," Hermione reminded briefly.

"Yes, to be precise, everything you will learn in my class in the future is completely different from the child's play magic you have learned before." Tiera said, "So just like Dumbledore's Army last semester It’s the same as in the training class. You first do the exercises and then the configuration. After the configuration is completed and I think you are qualified, I will teach you the spell and practice casting under my protection."

"But...but...but Tiera..." Neville asked, "I...my grandma...my grandma doesn't allow me to learn these...can I not learn it?"

"Of course you can." Tiera said with a smile, "You went through Dumbledore's Army training class last semester, and your actual combat ability is already stronger than 80% of the pass-level students at Hogwarts. You can choose a more relaxed defense class."

"Defense class?" Neville, Harry, Ron, Hermione and Ginny asked in confusion.

"With Principal Dumbledore's permission, Hogwarts has now split the original Defense Against the Dark Arts class into a Dark Arts class, taught by me, and a Defense class..." Tiera paused, "S Professor Nepp teaches.”

"S-Snape!" Neville almost screamed.

"Because of the current serious situation." Tiera explained, "Choose at least one of the black magic class and the defense class."

"..." Neville's face looked uglier than if he were crying.

"A compulsory course for students in fourth grade and above." Tiera added.

"But...but...but we last semester..." Neville said with a sad face, "We already learned it last semester...do we need to learn it again?"

"Last semester was illegal training and illegal gatherings." Tiera explained, "It does not count as normal school hours."

"But..." Neville wanted to say something else.

"Okay, let's go." Tiera interrupted, "Go and pack your things, because of the "Magical Union Economic Law", nearly two-thirds of the house elves were released inside and outside Hogwarts Castle. Factory, go to set up stalls, although some alchemical lifeforms have replaced some of the house elves' responsibilities inside the castle, but those alchemy lifeforms are still... well... still a little immature, and they don't do many things well. Wizards or wizards are needed. The house elves are giving instructions behind the scenes, and today, the house elves are busy in the kitchen preparing things for today’s dinner, and they don’t have time to instruct those alchemical lifeforms to help you make your bed and room, so you may need your own help.”

As Tiera was talking, the light door appeared again.

"Aha, Luna, welcome!" Professor Tiera said with a smile, walked up and gave Luna a big hug.

Luna seemed to be much more cheerful now. She blinked her smart eyes and looked at Professor Tiera and then turned to look at classmate Tiera——

"Aren't you all the same?" Luna asked, "Why do you have to say hello to me twice?"

"This way you will have two more friends." Tiera said with a smile, "Okay, go pack your things. We let a wave of house elves go, and the remaining house elves are preparing dinner. Maybe You need to make the bed yourself."

"Well... I'm looking forward to your classes this semester, Professor Tiera." Luna winked mischievously, then skipped towards the castle without looking back.
