Accuracy and flexibility have become another topic that Gale has recently started to practice after proficiency. At the same time, the two children who have returned to 19 Spider Tail Lane are also going to Evans' house to visit the Evans sisters.

"Gail!" Lily, who answered the door, happily opened the door after seeing who it was, and saw Seaver behind Gail. "Come on in, Mommy has made a delicious little biscuit! Penny is reading a book upstairs! ”

"This is Mr. Snape Jr." Mrs. Evans came out of the living room and greeted Severus with a smile when she met for the first time. "It's amazing that I've been living alone for so many years! Alright, let's go upstairs! ”

Gail took a breath of surprise, but then realized something, and followed Lily, who looked a little confused, upstairs.

Penny sat in the second-floor living room, with a thick biology book and Lily's subject textbook at hand. She lifted her glasses and looked at the three people who came upstairs with a little dissatisfaction: "Okay, I can't count on you anymore." What kind of school doesn't allow students to review and preview their learning knowledge during the holidays? It's ridiculous! ”

"Penny started to get angry when she knew I couldn't cast any spells with my wand during the holidays. It's been two weeks now, and it still hasn't deflated. Lily whispered to Gail, a little afraid.

Gail swallowed as well. I don't know if it's his delusion, but I always feel that after Penny spent an academic year in a boarding girl's school, the whole person has become imposing.

Severus was a little upset that Lily and Gail were silent: "Who emphasized wizarding secrecy during the Christmas holidays?" ”

Penny looked at Severus behind Lily and Gail, and lowered the arm around her chest, "Hello, you must be Mr. Snape." Thank you for taking care of my sister this year, you can call me Penny. ”

Such an opening immediately broke the confrontation and quickly shortened the distance between strangers. It seems that boarding schools are not for nothing! Penny has grown up great!

"Severus. Hello. Seaver returned the favor.

"Well, since there is a wizard secrecy law, then we have to follow it." Penny motioned for Lily to sit beside her, then nodded to Gail and Seaver, "Are your summer homework done?" ”

"Yes." Gale almost reflexively added "ma'am".

Penny nodded in satisfaction, stroked her hair tied into three strands, and said, "Speaking of which, I actually have an idea, hoping to make it happen during the holidays." Unfortunately, I had to wait because the underage wizards were not able to use magic while they were away from school. Or would you be interested in verifying it for me? ”

"Please." Severus said bluntly that he was also curious about Penny's thoughts. From Gail and Lily, Seaver learns that Penny is really a very thoughtful girl. It's an outstanding talent. And Penny is very self-disciplined and precocious for some reasons, which also makes Penny look at the problem more comprehensively although she is the same age as the three of them.

"You know, my school is special. The people I've been in contact with in the last school year have been a bit ...... height, so I also came into contact with some interesting books. These books gave me a little inspiration. "Before Penny starts to tell the truth about the content, she makes such a somewhat vague foreshadowing." I wonder if a water pipe is turned into a snake, eats a mouse, and uses a spell to stop the snake to turn back into a water pipe, will the rat die? Is the cause of death of rats social? ”

“…… Anything else? Gail didn't know what to say, so he continued to ask Penny.

"Turn a mouse into a cup," Penny said with a "push" motion, pushing a book off the table, and after picking up the book that had fallen to the floor, she continued, "The cup will surely break." At this time, if you stop with a spell, will the rat die? What is the cause of death? ”

"That ......," Lily interjected, "Penny, do you hate rats so much?" ”

Gail covered his face with a slap. Why is Lily's focus a little wrong? Shouldn't you be more concerned about Penny's mental health at this time? A 12 or 3-year-old girl shouldn't think about this kind of question at all! Especially a bit of a bloody problem!

Penny shrugged indifferently, "Since most of the experiments are done with rats, I'll just say rats." Of course, you can use other animals if you want. Spiders too! ”

Hehe, it's not good at all. Gail said in his heart, and turned his gaze to Seaver: This is what you promised, you do it!

Severus was lost in thought at Penny's words, and then hesitantly answered Penny's question: "If the spell is completely successful, both rats will die." The cause of death of the former is swallowing, and the cause of death of the latter is fragmentation. ”

"How do you prove it?" Penny persistently asked Severus.

Syver pondered his words and said cautiously, "In the case of the complete success of the Transfiguration Charm, the pipe is a snake. Assuming it is non-venomous, after a snake eats a mouse, the mouse's bones will be damaged during swallowing, and then the snake will digest it. Before digestion begins, the curse stops, the rat is dead and will not be resurrected, and the cause of death is squeezing, that is, snake swallowing. The same goes for the latter one. This can be known by logical reasoning, and does not require a magic spell. ”

"So what if I don't stop immediately after the cup that the rat turns into is broken, but first use the curse to stop as before, and then use the curse to stop? Will rats still live? If so, what is the cause of death? ”

"In the case of a complete success of the spell, the rat will definitely live!" This time, Lily joined in, and without waiting for Seaver to answer, she drew inferences from herself.

Gail covered his face and could barely bear to look at it. What kind of girl did you make friends with? It's scary here, I'm going home!

Penny seemed persuaded and didn't pursue the question, but then another question came to mind: "After the pipe turned into a snake, it had the habit of a snake, which is a successful transfiguration." So has anyone succeeded in applying Transfiguration on people? It's like a fairy tale that turns a prince into a frog or a swan or something. ”

Gale recalled, he didn't expect the example to happen, but he knew that after the fourth year of the original protagonists, the next heirs of the Malfoy family would have the nickname "White Glaze" from now on.

"And what about animals becoming people? If a rat becomes a human, will the rat also forget its own nature as a rat? Penny asked again.

Gail was silent and saw that Lily and Seaver were both lost in thought, and suddenly felt that his life was dark. "Let's have a little biscuit!"

As if she hadn't heard, Lily pondered for a moment before suddenly jumping up and running to her room, taking out a set of the story. Then, as if thinking of something, I flipped out of another book.

"These stories ......" Petunia had read the books and immediately understood what Lily meant, so she handed the book to Gail. Seeing that Gale waved his hand with little interest, he handed it to Seaver. All three ignored the "eating cookies" of Galtiyì.

Severus was first exposed to fairy tales for children, and Erin and Tobia were not the ones who could take care of children. He was a little surprised after a quick glance at the fairy tales on one side.

The person who wrote these stories was undoubtedly an ordinary person, but would ordinary people know so much about how magic works? It's so plain and widespread!

"How magic works is like a matter of logic, can you not dwell on it?" Gail clutched his forehead and thrust in.

"What did you say?" Penny reacted first and looked at Gail.

Gale was so stressed that he barely dared to breathe in the face of three pairs of eyes staring at him, but he patiently explained: "If we think of magic as a ...... of science"

"But science is science, it's materialistic! And magic ...... Oh! Penny was about to say "magic is spiritual", but she immediately understood what Gail meant.

"Materialism or idealism, in fact, is the present stage, pay attention, is only our division criteria at this stage. But this is only for the mind. But power is really existing, and our understanding is constantly changing with the development of things and the accumulation of knowledge. Gail spread his hands and said, "We don't know if we're making the right division." It's like I didn't know I was a wizard until I was 11 years old. To give a simple example, before we can count the number 2, we only know that 1 is stored in zài, but this does not mean that 2 does not exist in zài, but because our own cognition is limited, so we don't know 2. Or we can call 2 magic and 1 science. ”

"Yes." Penny recalls a conversation she once had with Gail in front of the lemongrass seed, "It's said that the people of Atlantis have both technology and magic, so they ......"

"So power is power, but the name and type are different, in fact, they are all the same!" Lily happily ends.

"We assume, are there other types of forces? Like 3? Severus asked another question after everyone had finished speaking.

Penny nodded: "We can't deny its existence because we don't know or don't understand." It is 'very likely' that it is stored zài. ”

"Isn't it a little too far-reaching for us to discuss this topic?" Lily opened her mouth a little puzzled, "In the past, we only knew 1, and now we know 2, but who knows where 3 is?" ”

"Let's have a little biscuit!" Gail pushes the cookie plate towards Lily, hoping to put an end to this dull academic topic.

Seeing that Gail and Lily were out of the way, Severus naturally kept silent. Penny didn't have the habit of singing a one-man show, so she naturally joined the ranks of the three of them eating cookies. What the four children present never expected was that the 3 in their mouths was engaged in a somewhat tragic counterattack battle on the other side of the ocean. However, it will be some time before this counterattack spreads to London.

So now, our four teenagers are still enjoying dessert with friends and family in the warm afternoon.
