"It's not an illusion, it's a fact-it's indeed brighter." Wang Dong curled a smile on his lips and said, "Let me explain it. The seed of lament can indeed purify the soul gem, but while it purifies the soul gem, it will reduce the maximum scale value of the soul gem to an extremely small extent..."

"...What does this mean!?" Apricot Sakura was a little uneasy. What the hell is the maximum scale reduction? She asked hurriedly.

"Well, that's right. Didn't I just make an analogy, saying that if the soul gem has a 1,000 filthy scale?" Wang tilted his head and said with a smile, "And then, later I carefully observed the energy changes in the soul gem when you just purified the soul gem, and found a very, very cute and disgusting fact."

"What fact? You said it!" Akiko Sakura looked at Wang Dong with a frizzy face - You said this person, why do you like to make people's appetites when speaking? If you didn't beat you, I'm afraid you would jump up and beat you to death!

"okok, let's assume that the soul gem has a scale of 1,000. Then when you use magic or generate negative emotions, the soul gem will accommodate a certain scale of negative energy, and the maximum capacity is to accommodate 1,000 scales of negative energy - I can't explain this, right?" Wang Dong looked at Apricot Sakura and Mamami.

"No problem, Lao Tie." Sakura Apricot nodded.

"Okay, then let's go ahead - and then I was thinking just now, you said... If a magic girl has a very good mentality and is difficult to develop negative emotions, and she basically doesn't use magic much, does it mean that her soul gem will produce dirty speed very slowly, almost one-tenth of other magic girls? In this case, the number of soul gems she uses the sorrow seed to purify the soul gems will also change very little accordingly. In other words, the number of sorrow seeds she needs can be described as very few compared to other magic girls. Maybe she only needs to purify once in a few years. One sorrow seed is enough for her for nearly ten years." Wang Dong raised his finger and said, "Although this possibility is very small, there are so many wonders in the world. Maybe there are such magic girls? Right?"

"If so, what?" Apricot Sakura looked at Wang Dong in confusion. She didn't understand what the meaning of Wang Dong mentioned this - what is the difference between using more and less? Don't you all use it?

"Think about what you did in the past... Oh, think carefully about the relationship between the magic girl and the witch. In order to maintain the balance of quantity between the two, do the Cupids have to balance the speed of the magic girl becoming a witch and the speed of the witch being hunted by the magic girl in a certain proportion?" Wang Dong spread his hands and looked through all the truth, and said naturally: "But - I mean - if - if there is really the magic girl I mentioned, wouldn't it mean that other magic girls have become witch-like, and she can still be as quiet as the soul gem? She cannot produce the resources needed by Cupid."

"So...father, what do you want to say?" Because he could not observe the energy changes like Wang Dong, Yukinoshita Yukino, who was already confused, frowned and asked.

"What I want to say is that in order to maintain the balance I just mentioned, the Cupids have made a balance mechanism in the magic girl's soul gem - or hands and feet." Wang Dong's face showed a sarcastic smile and said, "Kupi is really a powerful creature."

"The balance mechanism is the one you just mentioned, the one with the scale upper limit reduced?" Apricot Sakura asked hurriedly.

"That's right." Wang Dong nodded his head and said with a sneer: "That mechanism is probably like this. If a magic girl purifies his soul gem, the mechanism will begin to work. If it detects that this soul gem is often contaminated and often needs to be purified, then it will only reduce a very small part of the scale upper limit. If it detects that the soul gem is very contaminated and the purification needs are very little, it will reduce a large number of scale upper limits in one breath..."

"I understand." After Wang Dong's words fell, Yukinoshita Yukino nodded immediately and said, "In other words, by changing the total amount of filth that the magic girl can accommodate, we can control the speed of the magic girl's witch becoming, right?"

"Bingo." Wang Dong snapped his fingers quickly and said, "That's it. If this magic girl often uses magic to stain dirty, the scale will be slower, and if a magic girl is slower, the scale will be slower."

"Wait...that...what is the point of lowering the scale?" Sakura Akiko covered her head. She had never been to school, so she was a little confused about this knowledge.

"It's very simple. For example, if you could have accommodated 1,000 points of dirtyness, and if you use magic once, you will reach the limit if you use magic twenty times and have to purify it?" Wang Dong asked.

"Uh...yes." Akiko Sakura nodded - fifty times twenty is one thousand, she still knows how to calculate this.

"So, suppose that after you purify a few times, the upper limit of 1,000 points dropped to 900 points, a hundred reduction, which means that the number of times you can use magic power has been reduced by two times, and it has become eighteen times." Wang Dong said.

"Uh..." Akiko Sakura scratched her head-one hundred times, so the reduction of one hundred times was reduced by two times, and the reduction of twenty times was eighteen times... Yes, there is nothing wrong!

"And when you continue to use magic and continue to purify, your scale gradually decreases, drops..." Wang Dong looked at Sakura Apricot with a serious face and said word by word: "So assuming that when your scale limit drops to two hundred points, or even one hundred points, does it mean that if you use magic twice or three times, you will have to purify it?"

"I understand..." Wang Dong said this, and of course Akiko Sakura understood. She said with gritted teeth: "In other words, the decrease in scale means that the demand for the seeds of lament has increased, right?"

"That's right." Wang Dong nodded and said, "The speed of the scale drop depends on the degree of pollution you are. Magic girls like you and Mami who often use magic to fight will have a much slower decline in scale. If there are magic girls who rarely use magic and have no dirty long-term problems, their scale will drop rapidly."

"No wonder the number of magic girls and witches has always been in a delicate balance. So that's the case?" Apricot Sakura was very angry. This was the kind of angry look that only those who found out that they were fooled.

"Ahem, the point is not here, but now your scale has been restored." Wang Dong coughed twice and said proudly: "I just discovered that I can not only help you purify the filth, but also restore the scales that have been reduced by using the seed of lament. Therefore, your soul gem will become so clean after purification!"

"Teacher, you have this function!? It's so awesome!" The worship in Bamamei's eyes almost turned into a substantial light and enveloped Wang Dong.

"What is this function? Do you think of me as a washing machine?" Wang Dong reached out and knocked Bamami's head in anger, and said, "Okay, the matter has come to an end first. Tell Xingzi about the details and I'll go cook."

"Yes~~" Mami nodded with a smile. After watching Wang Dong walk into the kitchen, she took Sakura Akiko's hand and Yukinoshita Yukino sat at the dining table together.

"Who is your teacher?" Sakura Akiko's face was filled with a subtle expression at this time - roughly the same as the expression of the author when she saw the Bie Yunjian with an amplitude of 19.

The left eye says "Damn how is this possible" and the right eye says "Damn it is absolutely impossible".

"I met the teacher two years ago..." Since Apricot Sakura raised this question, Mami simply started from the beginning, and told Sakura Apricot what happened in the past few days two years later.

"Extra... alien!?" Apricot Sakura opened his mouth and held it in a long time before he could put it in a sentence: "I'm a little studying, I'm a fool?"

"Do you think ordinary Earthlings can detect the energy changes in the soul gem?" Yukino Yukinoshita glanced at Sakura Akiko and said, "And you have seen Earthlings transform into a washing machine to wash your soul gems?"

"No..." Akiko Sakura shook her head and muttered, "But... aliens or something..."

"Isn't Cupi an alien too?" Mamami looked at Akiko Sakura strangely and asked, "Why did you accept the fact that Cupi was an alien so simply, but it is so difficult to accept the fact that the teacher was an alien?"

"Isn't this natural! The form of Cupi can tell at a glance that it is not a creature on the earth!" Sakura Apricot looked at Mamami with confidence and said, "How can you tell someone's animation on Earth like a rabbit and a cat? You don't open your mouth and talk, and you can still talk about other people's animation?"

"...What you said makes a little sense..." Yukinoshita Yukino covered his face and said speechlessly: "My father, I blame you for looking like an earthling, hahaha..."

Then, an hour and a half later, Apricot Sakura knelt in front of Wang Dong with a pious look on his face, holding his hands and fingers together and pressing them on his forehead. In the eyes of Mamami and Yukinoshita Yukino, he whispered: "The God of Food from the Food Planet, I believe you are an alien! This dish should only be available in aliens, and I have never seen the Earth before!"
