"Everyone, do you like fishing?"

The next day, Fang Zheng just walked into the student union room and threw out these words, which directly confused the girls in the student union room.

“I like fishing.”

Ignoring the puzzled looks of the girls, Fang Zheng continued speaking.

"It's really satisfying to see those big fish that are completely clueless and take the bait, then realize something is wrong and struggle, but in the end they can only let me do whatever I want."

“……???”

The girls looked at each other, not knowing what Fang Zheng was going to say. In their memories, Fang Zheng didn't seem to be the kind of person who liked to talk about this kind of topic. However, Fang Zheng didn't care about their gazes at all, but walked in front of Nanakusa Mayumi and placed a few documents on the table.

"So, President, shall we go fishing?"

“…”

Nanakusa Mayumi did not answer Fang Zheng's question immediately. Instead, she curiously picked up the documents and looked through them. However, as she looked through them, Nanakusa Mayumi's expression became more and more serious, even a little gloomy. At this moment, Shiba Miyuki, Nakajo Azusa, and Watanabe Mari also noticed that something was wrong with Nanakusa Mayumi's expression, and they immediately became nervous.

After reading all the documents, Nanakusa Mayumi closed her eyes, took a deep breath, and then looked at Fang Zheng again.

"Is this true?"

"uh-huh."

Fang Zheng snapped his fingers and said nothing.

"What's wrong? Mayumi?"

At this moment, Watanabe Mari also looked at her friend in confusion, while Nanakusa Mayumi said nothing, but silently handed the document in her hand to Watanabe Mari. After reading it, the latter also showed a solemn expression. Then the document was passed to Ichihara Suzune, Nakajo Azusa and Shiba Miyuki respectively. After reading the contents, everyone's expression changed slightly.

"Where did you get the news?"

Watanabe Mari also restrained her expression at this moment and looked at Fang Zheng seriously, who shrugged his shoulders.

"Insider information cannot be disclosed for confidentiality reasons."

"Okay... I won't ask, but this is indeed a big deal."

Watanabe Mari also knew that she couldn't get any words out of Fang Zheng's mouth, so she looked at Nanakusa Mayumi again.

"What should we do now? It's fine if we don't know, but if this really happens, then we should have a solution."

"I will discuss this with Chief Jumonji and make a decision."

Nanakusa Mayumi was not the student council president for nothing. Although the news Fang Zheng brought was earth-shattering and frightened her, after coming to her senses, Nanakusa Mayumi quickly made a decision. She rarely tightened her face and glanced at everyone in the student council room.

"Only a few of us know about this. You are not allowed to spread it outside. Do you understand?"

"Um!!"

After reading the documents Fang Zheng brought, everyone knew how serious the matter was and nodded. However, Shiba Miyuki seemed a little uneasy and asked.

"Can't we take action first? If we really let them act, it will bring chaos and danger to the entire school..."

However, in response to Shiba Miyuki's question, before Nanakusa Mayumi could answer, Fang Zheng rolled his eyes.

"Only when the fish take the bait can we be sure there are really fish in the pond. You can't just fry the fish without even seeing the shadow of the fish. Alerting the fish will only cause more trouble."

"I agree with Kasugano-san."

Nanakusa Mayumi also nodded.

"Things that didn't happen, didn't happen after all, and we can't do anything about it. But now that we know the other party's plan, we have enough ways to take countermeasures."

Mayumi Nanakusa made the final decision, and the others had no objections, so they naturally agreed.

In the following days, everything was as usual, and Fang Zheng was slacking off as usual. Apart from being lazy in class, he assisted Shibata Mitsuki and Chiba Erica with their academic tutoring, and occasionally participated in small secret meetings held by Nanakusa Mayumi, the general manager of the club alliance Jumonji, and the discipline committee chairman Watanabe Mari.

Of course, for Fang Zheng, the current focus is naturally still on guiding the four girls in their studies.

This was actually not difficult for Fang Zheng, because the magic setting of this world was simply a high-tech version of the superpowers of the Toaru Majutsu no Index world, which was equivalent to adding an external auxiliary calculation output device to those who had special abilities. Well, Fang Zheng thought that he could consider spreading this world's calculation device when he returned to the Toaru Majutsu no Index world. At least it was more reliable than the "Fantasy Hand".

And the so-called "magic" in this world, in Fang Zheng's view, is just a form of developing and applying super powers.

Therefore, what Fang Zheng is doing now is to develop the abilities of the girls and make them better at using their own "magic".

For example, the one in front of us, Honoka Mitsui.

"Light waves are actually a very versatile type of magic."

Looking at the twin-tailed girl in front of him, Fang Zheng began to explain carefully.

"To be honest, I think the current magic courses are incomplete in many aspects. They should first teach students to understand the nature of their own abilities, and then extend from this point. Guangjing, you are a good example. The optical system has a wide range of uses, but you only use it for flash magic, which is a bit of a waste."

"But... I don't know much about these magics..."

Honoka Mitsui looked confused, while Fang Zheng shrugged.

"No, it's not a question of understanding magic, but understanding 'light'."

"Light?"

"That's right."

Fang Zheng nodded.

"Manipulating the vibrations of light waves. Once you understand how light works, you'll find that you can use it in many ways. For example, you can distort light or synchronize it with the surrounding light waves to hide yourself, like this."

As he spoke, Fang Zheng snapped his fingers, and the next moment he instantly disappeared in front of Mitsui Honoka. Seeing this, Mitsui Honoka's eyes widened in surprise.

Then the next moment, Fang Zheng appeared again.

"Or, you can adjust the frequency of light waves to create illusions."

As he spoke, Fang Zheng pointed his finger, and then a unicorn appeared out of thin air and came in front of Honoka. Honoka was stunned and speechless at the pure white unicorn in front of her.

"It is also possible to transfer light wave signals from far away, just like live TV broadcasts."

Fang Zheng waved his hand, and soon, the scenery in front of the two of them suddenly changed from the original training ground to an outdoor sports field in the school. Students running around and training could even be seen all around.

"The application of optics is the result of hundreds of years of research by humans."

Fang Zheng snapped his fingers again, and soon, everything in front of him disappeared again.

"So I think this is a good direction. If you want to improve your power, you must have an objective and rational understanding of your abilities. From this point of view, I actually don't like the current way of categorizing magic."

“Is there something wrong with the classification method?”

"Of course, something like the Light Wave Vibration System sounds too high-sounding. People tend to give it a subjective impression when they hear a new term. This is why your ability improvement is limited to this level. Even if you don't realize it, you will subconsciously regard the term 'Light Wave Vibration System' as a more difficult existence. If you were simply told that you are an 'Optical Ability User', perhaps you would be more relaxed."

Having said this, Fang Zheng chuckled.

"Perhaps it would be more appropriate to call you 'Pretty Cure'?"

"B-beautiful girl or something... it's too, too unsuitable for me!"

Hearing this, Honoka Mitsui's face suddenly turned red.

"Compared to Shiba-san, I'm nothing..."

"But you are also very cute. Don't underestimate yourself. There is no comparison between lilies and roses. Different people have different tastes."

“Wuwuwu…”

Seeing her friend blushing, Kitayama Shizuku next to her also spoke hurriedly.

"But Kasugano you're amazing, being able to use this kind of magic so smoothly, are you also a user of light wave vibration magic like Honoka?"

"Hey... this is a long story."

Having said that, Fang Zheng suddenly revealed a deep expression, sighed deeply, and then he looked at Mitsui Honoka.

"Mitsui, you may not know this, but in fact... I am your half-brother!"

“Hey…Hey hey hey ah!!?”

Hearing this, not only did Mitsui Honoka scream, but even Chiba Erica and Shibata Mitsuki, who were originally doing practical training nearby, looked over in surprise, and Kitayama Shizuku was even more stunned.

Under the gaze of the four girls, Fang Zheng sighed and put on an expression of great pain.

"You may not know this, but I was born into a wrong family. I shouldn't have existed, but I ended up here. And I didn't expect that my sister would be here too. That's you, Honoka!!"

As he spoke, Fang Zheng held Honoka Mitsui's hands, and the latter's eyes rolled around and her face turned red.

"Is this true? I actually have a brother? Are you really my brother?"

"Oh, of course it's... fake."

“…Huh?”

"Okay, just kidding."

Looking at Honoka Mitsui who opened her mouth wide, Fang Zheng chuckled and let go of his hand.

"As for why I can use light magic, I can't tell you, but I can tell you that I can use not only light magic, but also magic of each of your factions smoothly and freely. This is why I have the confidence to teach you... You don't think I'm just making fun of you, do you?"

“…You must be kidding.”

Hearing this, Honoka Mitsui did not react, but Chiba Erica next to her covered her mouth in surprise.

"Can you use all of our magic?"

"That's about it, so don't worry. As my guinea pigs, I will also tailor a magic system suitable for you as a reward. How about it? I think you should have no objection."

"Of course I have no objection. I can even say that I would love to have it. But...how can you achieve this? Ordinary magicians, no, even those powerful magicians I know, can't achieve this, right?"

"Hehe, that's because I'm stronger than them. It's a very simple answer."

"What are you kidding..."

“——hiss, hiss, hiss!”

However, before Chiba Erica could finish her words, suddenly, the horn made a shrill noise, followed by a loud voice coming from it.

"All students in the school!"

“Woooooa ...

Hearing the shrill roar, the girls hurriedly covered their ears, but fortunately, the announcer seemed to realize that there was something wrong with his volume and quickly lowered it.

"——Excuse me for being rude just now, everyone in the school. We are an alliance of people with the goal of abolishing discrimination in school."

"...An alliance of people with aspirations?"

"What is this?"

Hearing the voice coming from the loudspeaker, the girls looked at each other, while Fang Zheng crossed his arms and listened to their speeches with great interest.

“We demand to negotiate with the student union and the community alliance on an equal footing!”

"Haha, that's really interesting."

Hearing this, Fang Zheng sneered, then he turned around and gestured to the girls.

"Sorry, I have something to do and I have to leave first."
