Harry Potter and the Virtue of Miss Potter

As Yilong's voice faded, the surroundings grew brighter and brighter. Almost instantly, everything in Wumu's vision turned white, and she entered her mind in a radiant way, without her even realizing it.

Wu Mu kept his eyes tightly closed, his hands protecting his head in front of him.

[You're alright. You're currently in your mental space. After this, you can enter freely from now on. Just concentrate, and the system space will be ready soon. Now, I'll tell you the rules; remember them well.]

Yulong was much taller than Wumu, who, with a height of less than 1.6 meters, looked very small in front of him.

"Okay! Trust me! I'll definitely remember it!" Wu Mu had a "trust me" expression on his face, along with a hint of smugness.

[Alright, alright, I know your memory. You can't remember a single word when you're trying to memorize a book. Here's what I'll do: I'll give you a piece of paper with all the rules on it. You can take it out and look at it anytime if you forget something.] With that, Yilong casually produced a piece of paper and handed it to Wumu.

"Okay, okay." Wu Mu took the paper, sat cross-legged to the side, and began to read it.

The contents of the paper:

1. You are forbidden from telling anyone else that you are a time traveler, including your parents, relatives, and best friends.

2. You are not allowed to drastically change the plot. You can slow it down or speed it up, and you can change plot points that are not very useful, but important plot points cannot be cut because of you.

3. You can build good relationships with anyone in the story, except for the villains, which will drastically change the plot.

4. Do not ask the system for help without authorization.

5. It is forbidden to force the system to violate principles.

6. Remember that you are a time traveler, and don't get confused about the world you're traveling to.

7. If the plot changes drastically, the time traveler will be punished, and the system cannot stop or help them.

8. The transmigrator's identity must not be exposed by the people in the transmigrated world.

9. The time traveler can save or kill the characters inside.

10. The system must memorize the entire book of the Transmigration Rules and issue warnings and reminders when a transmigrator is about to violate them.

"The Laws of Transcending Time? What are those? You need to memorize an entire book, sigh, I truly feel sorry for you." Wu Mu hated memorizing the most, and upon learning that Yi Long needed to memorize an entire book, her heart sank a little.

[Hmm, not bad. I memorized it hundreds of years ago. Alright, system space, I'll take you on a time travel journey after I've rested.] Yi Long said, walking to his hammock and lying down.

"Huh?! Hundreds of years? You look only fifteen or sixteen years old now, how could you be hundreds of years old?" Wu Mu stood up and walked to Yi Long's side.

[What? I'm 676 years old this year.]

"What?! Over six hundred years old!!!"

Wu Mu: "..." No way, 676 years old? Did he eat the Philosopher's Stone from Harry Potter? How can he live for over 600 years like Nicholas Flamel!

[No need to be so surprised, I am the system, born with the ability to live forever.] Yu Long jumped off the hammock.

[It's about time, let's begin!] Yilong walked to Wumu's side.

"I'm ready!" Wu Mu raised one hand above her head, looking genuinely excited.

[Remember, when you wake up, you should be in Petunia Dursley's room. Your name is 'Walt Potter.' Your appearance will change; you should look like Lily Potter.]

"Lily? She should be my mother when we go to that world."

[Yes, remember those rules. If you need anything, just call me in your head; I can hear you. Don't call me like you would in your room.]

"Hmm... Yilong," Wu Mu's face showed worry as she tugged at Yilong's sleeve, "What about my parents?"

[It's alright, Heaven has created a false version of you to continue living. When you return, you will not only have the memories of when you were gone, but you can also completely integrate into the world.] Yilong smiled.

Yilong: "..." I wonder if she can hold on for long...

"Oh, then I'm relieved! Let's begin!" Wu Mu felt much more at ease after hearing Yi Long say that.

[You might feel a little unwell later, please bear with it.]

"Oh, okay! Don't worry!" Wu Mu grabbed the hem of Yu Long's clothes with one hand. She told him not to worry, but she was still a little scared to hear a grown man who was over six hundred years old say that.

Yilong looked at the little boy clutching the hem of his clothes.

Yilong: [...] I hope she can hold on. She will suffer the same pain as me. Thirteen years old... Last time, a fourteen-year-old transmigrator couldn't withstand the distortion of his body and the surrounding environment, plus he was too young... Sigh, why can't it be that the older you are, the harder it is to endure?

Wu Mu: "..." Is he... worried? Is he afraid I won't be able to hold back later? "It's okay! Trust me!" That should put his mind at ease!

Yilong: [...] She... [To tell you the truth, the younger you are, the more pain you suffer. You are the youngest child the system center has ever cared for...] Will she be afraid after hearing this?

"Don't worry! I can do it!"

[Alright, let's begin!]

Yilong: I'm really afraid he'll die because of this...

[Lai Si Si Da De Chua Fu Ling (onomatopoeia for a spell)!] Along with the dragon's voice came countless square mosaics, like mosaics, repeatedly folding and unfolding on their bodies.

"Well……"

Wu Mu: "..." Oh my god! It's so...so painful...

[Uh... um... if it hurts... just scream it out, um...] Yilong looked at her as she tried to hold it in, his eyes full of worry.

"I...I'm fine. By the way...are we suffering the same pain?" Wu Mu still tried to hold back, and although she was in a lot of pain, her face still showed the words "I'm fine".
