Chapter 443 Time Turner

"Don't worry, Professor, I won't force myself." Yang Tian nodded vigorously: "Besides, if Hermione really can't hold on, I will let her put it down."

"Humph, I may not listen to you." Hermione said unconvinced.

"This matter is not negotiable." Yang Tian's smile was still gentle, but his tone was very firm and unquestionable.

Hearing this, Hermione opened her mouth and tried to refute, but in the end, she hung her head in frustration.

Seeing this scene, Professor McGonagall said happily: "Since you said so, I feel relieved. Hermione is great, but too stubborn. It's a good thing to have you watching her... and here's what I give you." As she spoke, she took out a long golden chain from her pocket, with a small, sparkling hourglass hanging on the chain.

"What is this, Professor?" Yang Tian and Hermione came forward curiously.

"This is a time converter." Professor McGonagall explained in detail, "If you turn it back once, you can go back one hour. The more times you turn it back, the further back you can go."

Sure enough, just like in the original book, Professor McGonagall took out this treasure: "Due to your course problems, Professor Flitwick asked me to apply for this thing from the Ministry of Magic for you. To be honest, it is not easy to get it. The two of us wrote several letters to apply for it... Moreover, there is only one for the two of you."

"So, we're going to use this thing to make up for the overlap in classes?" Hermione asked cautiously.

"Yes." Professor McGonagall's tone suddenly became serious, "Before you get it, I must tell you a few things."

Seeing the two nod, the professor continued, "First of all, you must promise not to use it for anything other than academics."

"Of course, we can definitely do that." Hermione answered loudly, but then she looked at Yang Tian in astonishment.

Professor McGonagall's eyes also became sharp, and her target was also Yang Tian. This brat didn't even answer?

"Oh, please don't misunderstand me. I really don't mean anything else." Yang Tian explained quickly, "I just want to ask if I can study this thing. First, I want to understand its manufacturing process. After all, this kind of alchemical tool is not easy to make. Second, I am also very interested in the principle of time involved."

"I knew it!" Professor McGonagall patted her head helplessly, as if she had expected it. "But I must tell you a fact. The Time Turner is a very dangerous alchemical tool. You must understand that no one can really change time and history! No one!"

Seeing that Yang Tian still had an evil intention, Professor McGonagall had to continue explaining: "Yang Tian, ​​I know you don't believe it, but that is the fact. There is a saying that goes, if you want to gain something, you will inevitably lose something... The more you want to change the outcome of an event that has already happened, the greater the price you will pay... For example, many wizards have accidentally killed their past or future selves in order to tamper with certain established facts..." In the following time, Professor McGonagall recounted countless real cases, just to make her favorite disciple dispel his dangerous ideas.

Some of these stories are heart-wrenching, some are creepy, and others are filled with endless sadness and helplessness, but in the final analysis there is only one result: tampering with the results will do more harm than good!

At this time, Yang Tian seemed to be lost in endless contemplation. From each event, he heard another layer of relationship: if time is regarded as a rule, then there must be other rules in the long river of history. Only with the joint support of these rules can time and history be fixed... Although he didn't know how many rules were involved, Yang Tian was sure of one, that is, the rule of cause and effect.

If time is a ruler, then cause and effect is like a spider web. Each scale on the ruler may be equipped with a spider web, but there are connections between spider webs. If a spider web on a certain scale is damaged, it will inevitably cause the spider web on the next scale to break. That is really a ripple effect...

The reason why Yang Tian didn't take Professor McGonagall's words to heart before was that in the original book, Harry used the time-turner to change the final results of many events, but he was still safe and sound. In his opinion, this was the most effective slap in the face of the so-called "real case".

But now, Yang Tian didn't think so. Maybe the things Harry changed were just small things, so the consequences he suffered were not serious; or maybe, Harry himself was the protagonist of the world, and was loved and protected by this world.

But no matter what the situation was, at least Yang Tian didn't dare to try it easily. He never thought of himself as a protagonist, and he would not put the final result on the so-called change of time. If he was not careful, he might become one of the many cases...

With this thought in mind, Yang Tian said solemnly: "Don't worry, Professor McGonagall, I have fully realized the seriousness of this matter. Please believe that I will never act rashly."

Professor McGonagall was relieved after hearing this and said, "Then let's move on to the next one. You must not meet your past selves when you go back in time, and try not to attract too much attention... Also, you can't go back in time for more than five hours at a time. This is the safest time..."

The two kids listened attentively and nodded from time to time in agreement.

"The last thing, the two of you must not tell anyone else about the Time-Turner. Absolutely not, including anyone in your study group! Can you do it?" Professor McGonagall asked seriously again.

"Don't worry, Professor, we can keep this secret." Hermione said seriously. This time, Yang Tian also nodded solemnly...

Because they talked with Professor McGonagall too late last night, when Yang Tian and Hermione arrived at the Ravenclaw table the next morning, the young wizards from various colleges had almost all arrived.

As soon as they sat down, Penelope handed them a piece of parchment: "Here, the new schedule for the third grade... I don't know what you were thinking, but you have to make yourselves so tired."

“I’m more curious about how you guys are going to take this course? There are a lot of overlapping courses,” Padma said with a little concern.
