After signing the contract, Fang Zheng drove back to the research institute with Ruiko, Kuroko, and Kiyama Haruo. As soon as they entered the gate of the institute, they saw Ram and Rem standing there, and they bowed to Fang Zheng together.

"Welcome back, Master Fang Zheng."

"Welcome back, Master Fang Zheng."

"Well, I'm back. Has the person been sent here?"

Fang Zheng nodded to the two maids and then asked. Hearing his question, Ram also gave a quick answer.

"Yes, Master Fang Zheng, the person has been delivered. Rem and I personally escorted him. The journey was smooth and there were no problems."

Ram and Rem have been in this world for half a month. Although they were not used to it at first, they quickly adapted to the environment of this new world.

After all, people in the fantasy world are more adaptable than those in the scientific world. For Ram and Rem, the things in this world are quite special, but not so special that they overturn their common sense. Not to mention, there is not even a person in this world who can fly in the sky...

As for those people with special abilities, in the eyes of the two, they were no stranger than magicians and elves.

In fact, even the current Ram, if we don't consider the magic power reserve, she can fight with Misaka Mikoto.

"Very good, let's go."

After listening to Ram's report, Fang Zheng nodded, and then led everyone to the depths of the research institute. Hei Zi and others followed Fang Zheng to the depths of the research institute in confusion, and then Fang Zheng opened the door and led everyone into one of the rooms.

"This is……"

Seeing the scene in front of them, Kuroko and Ruiko were both shocked. They saw a room similar to a large hospital ward, with more than a dozen devices similar to freezing chambers, and in these freezing chambers, there were boys and girls who were not much different from their age. At this time, the two of them had already guessed that these should be the children that Kiyama Haruo mentioned.

"Mr. Fang Zheng, have you known this for a long time?"

Shirai Kuroko reacted quickly. She immediately looked at Fang Zheng in surprise and asked her question. After all, based on what Shirai Kuroko saw just now, when they came back, the two maids had already brought the person over. That meant that before Fang Zheng set out to look for Kimura Haruki, he already knew about Kimura Haruki!

"Of course, knowing yourself and your enemy will ensure victory in every battle. Do you think I just rushed in out of boredom? I'm not Misaka Mikoto."

Fang Zheng chuckled. He had already investigated the location of these children and obtained permission from the tree diagram designer. Then he asked Ram and Rem to pick them up. Now it seemed that everything was going well.

"Well……"

Logically speaking, Shirai Kuroko should have immediately refuted Fang Zheng's slander against her beloved elder sister, but she... really didn't have the confidence to do so.

After all, what Fang Zheng said was true.

After casually saying "heizi", Fang Zheng turned around, took out a small gadget from the side and threw it at Kimura Haruo.

"Here, a portable personal terminal. You can use this."

“That’s it…?”

Looking at the strange machine in her hand, which was only slightly larger than the GBA, Haruki Kiyama was also confused. She reached out and turned on the switch, and soon a holographic projection screen and keyboard appeared in front of Haruki Kiyama. Of course, Haruki Kiyama was not too surprised by this. She quickly reached out and tapped on the virtual keyboard a few times, and then Haruki Kiyama's eyes suddenly widened.

"This, this...how is this possible?"

Just now, Kimura Haruo had only tested the computing power of this strange machine and input a set of data to obtain the result. Logically speaking, even a tree diagram designer would need several hours to obtain the result. But what Kimura Haruo did not expect was that as soon as he pressed enter, the result appeared in front of him instantly!

This is simply impossible. How can such a small box have such a high computing speed? Could it be that...

Thinking of this, Kimura Haruo's face changed drastically. She looked at Fang Zheng with a pale face.

“You’re using a quantum system?”

"Haha, of course, who still uses those antique supercomputers these days?"

Fang Zheng snorted softly.

"A 1,500-bit quantum computer is enough for you, right? If you can't come up with one, I think that's your own problem. Don't blame me."

"No, I won't!"

At this moment, Kimura Haruo was so excited that her hands and feet were shaking, and even her walking was a little deformed. Kimura Haruo held the personal terminal carefully as if it were a treasure, and placed it gently on the table, as if it was a glass product that would break if a little more force was applied.

"I will definitely wake up those children, thank you!"

After saying this, Kimura Haruo bowed deeply and respectfully to Fang Zheng, then sat down on the chair and began to work quickly.

Seeing this scene, Riri Saotome came over curiously.

"Mr. Fang Zheng, is your little box really better than the tree diagram designer?"

“Of course, technology is advancing.”

Fang Zheng laughed and thought he was joking. He was using a quantum computer, and the designer of the tree diagram was at best a supercomputer with a silicon-based chip. What was the use of that?

In Fang Zheng's opinion, only an illiterate like Aleister who has no culture, no knowledge, and no skills would come up with such a stupid idea to launch the tree diagram designer into space in order to prevent it from being stolen. The development of science and technology is geometric. What can a supercomputer based on silicon chips do, no matter how powerful it is?

Let alone quantum systems, if a carbon-based chip is commercialized, this broken computer will be a junk that no one wants even if you give it a lot of money. Only an idiot magician like Aleister would be so stupid as to treasure such a thing that may be completely obsolete in a few years.

This is the same level as those idiots who thought their Ruby graphics cards were forever, but were beaten by GTX to the point where they couldn't even find their mothers.

Academy City is thirty years ahead of the outside world. If you continue like this, you might wake up and find that they are thirty years ahead of you.

Of course, if you put your supercomputer on the ground, at least you can pull it out and upgrade it when technology innovates. But you insist on launching it into space... Hahahaha, even an idiot can't think this way.

This is also why Fang Zheng can do whatever he wants to the tree diagram designer. The computing power of the two is not at the same level. It's just like an ape-man with a stone axe fighting against a sky rail gun. Fang Zheng didn't even use his strength and it fell down. As for the guardian hacker, it's also useless. Only the skills of both sides based on the same foundation are meaningful. My speed is 100 million times yours. Even if you hone your skills to the pinnacle, no matter how high your martial arts skills are, you can still knock me down with one shot.

"Okay, let's stop here for today. It looks like she will be busy for a while."

Fang Zheng glanced at Kimura Haruo who was already working, then quickly looked away and looked at the two girls in front of him.

"You can go home too."

"Hey? Are you going back now?"

Hearing Fang Zheng's words, Saten Ruiko immediately screamed.

"Mr. Fang Zheng, didn't you say you wanted to train us how to fight?"

"It's late today. Come earlier tomorrow morning."

Fang Zheng glanced out the window and saw that it was already evening. Shirai Kuroko also glanced at the time and his expression changed immediately.

"Oh no, the door is under control... Then, Mr. Saten, Mr. Fang Zheng, I'll take my leave first!"

After saying this, Shirai Kuroko turned around and left in a hurry, and Saten Ruiko could only nodded helplessly and left the research institute.

Frankly speaking, Ruiko Saten did not sleep well that night. What happened to Haruki Kiyama made her feel a little uneasy. She had never thought that there was such a dark side under the Academy City, and she had never thought that those crazy scientists would do such a thing to a group of children.

All of this made Ruiko Saten unable to sleep. She didn't know how long it took before she fell into a deep sleep...

The next day, when Saten Ruiko arrived at the institute, she was still a little tired. However, after entering the institute, Saten Ruiko quickly cheered up and was then taken to another laboratory by Ram.

"Ah, Mr. Founder, good morning."

"Hello, Tears."

Facing Lei Zi who was full of energy and greeted him, Fang Zheng nodded, while Lei Zi looked around.

"Where's Dr. Kiyama? Have those children woken up yet?"

"It's not that fast, you think this is a magic trick."

Fang Zheng shrugged.

"According to Kiyama Haruo, it will probably take another week or so... But it doesn't matter, it's better to be safe than sorry. Okay, now let's talk about you."

Hearing this, Riri Saotome quickly cheered herself up. Then she saw Fang Zheng make a gesture, and soon, Ram and Rem each came to her with a strange object.

"This is……"

Riri Saten blinked, looked at the long sword in Ram's hand, then looked at the thing that looked like a staff in Rem's hand, and scratched her head a little puzzled.

"Mr. Fang Zheng, what is this?"

In Saten Ruiko's opinion, these should all be weapons. Does that mean she should fight with weapons? But doesn't that mean she should use her abilities?

What is going on here?

"Considering your situation, you are not good enough to use a groundbreaking fighting method, so I think it is better to just use the existing one."

As Fang Zheng spoke, he looked at Saten Ruiko, smiled slightly, and spread his hands.

"Okay, then choose between Wind Sword Master and Storm Fury."
