Harry Potter and the Old Ones

After that, the campus life returned to calm, because Professor Sprout's Mandrake still had a period of time to mature, so Tierra had to bear the identity of "Gilderro Lockhart" first, and lived in Hogwarts. He taught Defense Against the Dark Arts, which was a bit difficult for Tierra——

It's not a teaching problem, it's not a problem at all to fool a few Defense Against the Dark Arts lessons with Tierra's knowledge reserve.

But every time after class, the endless little wizards who came to him to "ask questions" made Tierra tireless——

Most of them came to him for autographs, and only a few were for the purpose of seeking knowledge.

But no matter if they come to ask for an autograph or to ask a question, Tierra has no choice but to accept all comers in order to create a good character. Even those students who ask questions, Tierra has to use Gildero Lockhart's face Greasy said:

"Want an autograph?"

"Um... oh, no, no need..." a slender, handsome, brown-haired Hufflepuff fourth-year boy said, "Professor Lockhart... I just have an idea I want to ask. When you talked about the construction of altars in ritual magic, you talked about how to use ancient runes and Latin to construct ritual altars, but if we replace part of the Latin with arithmetic configurations...will it make the construction of altars Make it easier?"

Tierra looked at the big boy in front of him with some surprise, she never imagined that under the education system like Hogwarts, students who come up with innovations at the first contact with ritual magic can be cultivated.

"Yes, very good...Mr...Mr..."

"Professor Diggory," said the boy, "Professor Cedric Diggory."

"Cedric?" Tierra looked at Cedric with some regret——

Smart, handsome, and judging from the original book, he is an enthusiastic big boy.

When I was watching movies or reading novels, I didn’t feel much about Tiela. I only thought of Cedric as a tool man who changed from beginning to end. All his good things were for the last Avada Kedavra. In order to force Harry to embark on the path of the savior.

The so-called tragedy is to destroy the beautiful things for others to see. Rowling understands the core of tragedy.

But now this tool man is standing in front of Tierra alive, Tierra can't help but feel a lot of emotion.

"Yes, Cedric, very smart. In fact, to build a ritual altar, you can use only a few simple ancient runes, and use arithmetic models for the rest." Tierra patiently answered his doubts.

"But why are the altar configurations in most ceremonies in ancient runes and Latin?" Cedric asked again.

"Because the error tolerance rate of the arithmetic model is too low." Tierra explained, "You use ancient runes and Latin to build altars. If you write a wrong symbol or spell a wrong sentence, you will hold the most serious ceremony. The consequence is at most that the ceremony altar exploded, and even if the key symbols were not wrong, the ceremony can still continue, but the effect will be worse."

"However, if arithmetic models are used to construct rituals, a tiny calculation error will lead to inevitable consequences. Taking the demon summoning ceremony as an example, Agatha Morey, the author of "Demonology in the Fifteenth Century", is because of substituting Mistaking a symbol led to the summoning of demons far beyond her expectations, triggering the infamous Harz Mountain incident in the sixteenth century," Tierra said.

"From then until 1840, the Ministry of Magic throughout Europe, including the British Ministry of Magic, listed the method of using arithmetic configurations to construct ritual altars as black magic equivalent to the three forbidden spells. Once discovered and used, Spread and learn, you will immediately get a one-way ticket to Azkaban." Tierra said, "Even now, the book "Demonology of the Fifteenth Century" is still in the restricted section of Hogwarts, The method of publicly teaching underage wizards how to use arithmetic configurations to build ritual altars will still be regarded as an irresponsible behavior by most wizards."

"Okay professor, I understand." Then he asked some other questions, all of which were answered by Tierra.

"Thank you, Professor Lockhart, you are indeed a great wizard!" After all the questions were answered, Cedric bowed slightly, "Goodbye Professor."

"Goodbye." Tierra also greasy returned the salute.

After Cedric left, Tierra waited in the black magic office for a while, then put on her coat and walked towards the library.

"Hi, Mrs. Pince." Tierra grabbed two books from the restricted section of the Hogwarts library with Gilderoy Lockhart's face on them, and placed them on the desk at the front desk of the library. on, "I would like to borrow these two books."

"Lo, Professor Lockhart!?" Mrs. Pince said a little flattered, and then picked up the two books on the table——

""Demonology in the Fifteenth Century" and "Solomon's Little Key"?" Mrs. Pince asked in amazement, "What are you borrowing these two books for?"

"You know, Mrs. Pince, this time Voldemort regained his power by summoning demons. Although I destroyed the ceremony, it still caused a very serious impact. This made me realize my own shortcomings in this area, so I think I should complete this piece of knowledge." Tierra said.

"You are so eager to learn." Mrs. Pince admired, then took out a borrowed booklet, wrote "Demonology in the Fifteenth Century" and "Solomon's Little Key" in the blank space of the last line, and pushed the booklet to the Tierra——

"Please sign here," Mrs. Pince said.

Tierra picked up the pen and wrote the name of "Gildroy Lockhart" in the blank space.

Mrs. Pince pulled the book back, and then went back and forth carefully looking at the signature of "Ghidroy Lockhart"——

"Your signature... seems to be different from the previous ones..." Mrs. Pince said hesitantly.

"My hand is hurt." Tierra raised her right hand and waved——

On the palm of his right hand was a scorched black mark that seemed to be left after being branded with a soldering iron. It was really the mark left on the palm of Tierra's palm with a burning wand under the watchful eyes of everyone when he was making a show that day.

"Oh, my God!" exclaimed Mrs. Pince, "your hand...isn't that the scar from that day? Isn't it healed?"

"It can't be good." Tierra said with a sad look, "My magic power is not enough to defeat the half-mad Voldemort, so I had to use an ancient magic that I got when I explored a ruin, by sacrificing my wand, In exchange for a short period of powerful power..."

"This also left a permanent, indelible scar on my hand. This scar is too deep and has already hurt my nerves. I'm afraid my right hand won't be as flexible as before." Tierra said.

"You are really great!" Mrs. Pince said with tears in her eyes.

"No, Mrs. Pince, it's nothing. For the peace and stability of the magic world, my sacrifice is nothing." Tierra said, picking up the two books from the table, "Then I will leave .”
