As things developed to this point, Fang Zheng could almost guess what was going on.

Obviously, the magical girls in this "backside world" have a set of cruel survival rules. The creature called QB makes them sign contracts and become magical girls by satisfying their wishes. However...

"She is a little girl after all. Once you hear something like this, you know it will not end well."

Fang Zheng shook his head helplessly and then sighed.

"Hey? Teacher, how did you know?"

Hearing Fang Zheng's sigh, Xiaoying couldn't help but ask curiously, and Fang Zheng shrugged his shoulders.

"Although I don't like that thing called QB, I admit that one of its words is correct, that it helps those girls fulfill their wishes, so those girls must accept the result of the exchange. But the little girl is still a little girl after all. Anyone who is a little mature will carefully consider the matter of fulfilling any wish."

"Why, teacher?"

At this moment, Chise also raised his own questions out of curiosity.

“It’s very simple.”

Fang Zheng sighed.

"You may not know this, but in other worlds, it is not difficult to make wishes come true. For example, in my world, mages and warlocks can learn spells called 'Limited Wishes' and 'Prayers'. In the world of Xiao Hei and Illya, there is a 'Holy Grail' that can make any wish come true."

"Hey? Is there anything like this?!"

Hearing this, the girls were stunned. Even Homura Akemi, who was standing silently nearby, looked at them in surprise.

"But do you think that's a good thing?"

At this moment, Xiao Hei sneered and spoke.

"In fact, anyone who pursues this kind of result will end up in a tragic end."

"Why?"

“It’s very simple.”

Fang Zheng snapped his fingers.

"Because when you made a wish, you only thought about the result, not the process."

"…May I ask what this means?"

At this time, Homura Akemi, who had been standing in the corner in silence, suddenly asked, and Fang Zheng glanced at her and continued speaking.

"It was once recorded that a wizard performed the 'Limited Wishing Spell' and made a wish that 'I want to become the richest person in the world'. How do you think this wish will come true?"

"Um……"

Hearing Fang Zheng's question, the girls frowned and thought hard, and then Nanoha spoke.

"Will it be like in fairy tales, where there will always be gold and silver treasures in his pocket and he can never spend them all?"

Then Sakura also gave her answer.

“Perhaps a mountain of gold will suddenly appear in front of him?”

"All of these are possible, but the results show that there is another outcome."

Having said this, Fang Zheng smiled slightly.

"He was transported to a world full of gold, silver and treasures. How about that? This can be considered as the fulfillment of his wish."

"Well... then what? How's that wizard doing?"

At this moment, Zhishi also looked at Fang Zheng curiously and asked, and Fang Zheng chuckled.

"Dead."

"Why……?"

Upon hearing this answer, the girls were all stunned.

"W-why?"

"Because there was nothing but gold and silver treasures, the wizard starved to death while holding the gold."

"this……"

"That's right, because when he made the wish, he only thought about money. He didn't consider that in addition to money, he also needs more things, such as food and resources. These are the basis for a person's survival. Without these, even if you have a lot of money, it is still meaningless."

As he spoke, Fang Zheng snorted and glanced at Illya and Xiao Hei.

"In their world, someone once tried to use the Holy Grail to achieve world peace, eliminating the desire for fighting and war. But do you know how the Holy Grail intends to fulfill his wish?"

"……?"

"Kill them all."

Fang Zheng spread his hands again.

"As long as we kill all the people in the world, there will naturally be no more fighting and war among humans."

"hiss--!"

Hearing Fang Zheng's answer, everyone gasped.

"Fortunately, he was stopped in the end, so the world did not have the peace he wished for. But all this tells us a truth, that any goal can only be achieved through your own efforts. Many times you have to remember that if you rely on external forces to realize your wishes, then it is very likely that the situation will become completely different from what you imagined."

As he spoke, Fang Zheng looked at Homura Akemi again.

"Because, after all, the hand that grants wishes is not on your body, so it is naturally impossible for it to be as you wish."

“…”

This time, the girls fell silent and said nothing.

"alright."

Seeing that the atmosphere was a bit depressing, Fang Zheng clapped his hands and stood up.

"We have a general understanding of the situation now, but this is just information we have heard. We still need to practice to determine the exact situation."

"What are we going to do, big brother?"

Xiao Hei raised his hand curiously and asked while jumping around.

“The first is the most critical point.”

Facing Xiao Hei's question, Fang Zheng raised a finger.

"That QB said that all witches are transformed from magical girls. Although this seems to be true at present, seeing is believing. So what we have to do next is to find a witch and see if she is transformed from a magical girl."

"You are not planning to communicate with the witch."

Hearing this, Homura Akemi couldn't help but speak.

"Those witches can't communicate with us at all. They are left with only despair and anger. There is no way to talk to them!"

"I have my own way."

Fang Zheng obviously would not change his mind because of one or two words from Akemi Homura. Of course, even if the witch could not communicate with words, it would not be a big problem for Fang Zheng, but...

Thinking of this, Fang Zheng once again glanced at the bracelet in his inventory.

Forget it, forget it, it’s going to rain and girls are going to get married, it’s all fate.

“I want to go too!”

However, to Fang Zheng's surprise, at this moment, a strange voice suddenly came from the other side. He turned his head and saw that Tomoe Mami had woken up at some point and was standing up with the help of the wall. She looked as if she had been seriously ill. Her face was pale without a trace of blood. But even so, Tomoe Mami still looked at Fang Zheng with a firm and persistent look.

"Please take me with you. I am familiar with this place. I know where the witches are!"

"good."

In response to Mami Tomoe's request, Fang Zheng nodded nonchalantly.

"In that case, let's come together."

"etc!"

However, just as Fang Zheng finished speaking, the door was suddenly pushed open, and then Sakura Anzi popped her head out from outside the door, holding a chocolate bar in her mouth.

"You guys seem to be talking about something very interesting, why not add me in?"
