After getting through the initial novelty, Katsuragi immediately returned to boredom with school life, if it weren't for the fact that there were still seven palaces and six flowers in the school, and the blue in his eyes was strongly blocked, he would have wanted to take a leave of absence and go to work on something else.

After a few days of busy classes, Katsuragi also ushered in the weekend he had been looking forward to.

Although the coldest weather of winter has gradually passed, the warmth of spring has not yet arrived, so the clothes of people on the streets have not changed much as always.

"Whew!" Looking at the majestic campus in front of him, Katsuragi was not only a little amazed, but also the top university in Japan, Tokyo Institute of Technology, which is also the world's top university!

Looking at the address on his phone, Katsuragi stepped into the campus, and the school was basically full of young people, although Katsuragi was a little immature in it, but it would not be strange.

"Area B...... The third floor!" Katsuragi slowly walked to the location on the address according to the instructions on the map, he came today to find someone, a famous professor in this school, Toru Shigemura.

"It should be here!"

Standing in front of an office, Katsuragi knocked lightly on the door, speaking of which, it was not easy for him to meet this time, and he also used the identity of the boss of ALO to succeed, after all, he was not a student of this school, and he had no contact with Toru Shigemura.

If he rashly uses his identity as a little bird You Guimu, it is estimated that the possibility of being turned away is very high.

"Please come in!" A calm voice came from the room, and Katsuragi pushed open the door and walked in, a middle-aged man with a beard and slightly gray hair was calculating something at his desk with his head down.

"What's the matter?"

It seemed that he was busy with some important question, and Shigemura Tetsudai didn't look up at Katsuragi and asked, maybe he thought it was a student or an assistant or something!

"Hello, Professor Shigemura, I'm sent by KAMI to learn more about the AR Extended Reality Device!"

Gui Mu didn't care, and said the identity he had arranged for himself straight to the point.

Hearing Katsuraki's words, Shigemura Tetsudai was a little surprised, and then raised his head, and when the two looked at each other, Katsuragi keenly found that Shigemura Teruda's eyes were full of shock, as if he knew him.

"It's you!"

Sure enough, Shigemura couldn't help but say something, which made Katsuragi feel a little puzzled, and couldn't help asking, "Professor Shigemura, do you know me?"

Shigemura Tetsuda's hand holding the pen paused slightly, then stood up, came to Katsuragi's side, invited him to sit down, and said: "Little bird Yu Katsuragi, the survivor of the original SAO, is known as the Demon King!

Katsuragi frowned, did not speak, and looked at Toru Shikimura with an inquiring gaze, quietly waiting for his explanation.

"I know Kikuoka-kun from the Ministry of Internal Affairs and Communications, and I know this through him!" Seeing Katsuragi's eyes, Shigemura Tetsudai didn't hide it, and directly gave an explanation: "Kayaba Akihiko is my student, so when you were trapped in the SAO, I was the first person to be found by the government to help!"

Katsuragi almost forgot that in addition to being a professor at Tokyo Institute of Technology, Tetsudai Shigemura was also the teacher of Akihiko Kayaba, Nobuyuki Sugo and Rinko Kamiyo.

It can be said that Akihiko Aoba was able to develop Sword Art Online without the help of Teru Shigemura, so it is not so surprising that he has some connections with the government.

"That's right!" Katsuragi nodded, no longer confused that Toru Shigemura knew his identity.

"I didn't expect you to be the person sent by the KAMI company!" Shigemura Tetsudai sat opposite Katsuragi and looked deeply at Katsuragi with a strange gaze and said, "There have been rumors that the boss behind the KAMI company is actually a teenager, could it be you?"

"Hmm!?Does it have any effect?" Katsuragi didn't answer, he looked at Shigemura Teru calmly, a little vigilant in his heart, he always felt that Shigemura Toru looked at him a little differently, as if he wanted to get something from him urgently.

"No, it's nothing!" Shigemura Tetsudai was slightly stunned, and then smiled: "I'm just a little curious, I asked Kikuoka-kun about this news before, but he didn't tell me." ”

"It's a company secret, please forgive me for not being able to tell you!I'm sorry!" Katsuragi shook his head, not telling Shigemura that he was the boss behind the scenes, although he felt that the other party had already seen it.

"That's it!" Shigemura didn't mind, pushed down his glasses, squinted at Katsuragi and asked, "Then what is the purpose of Mr. Kotoriyu's coming here today?"

"You can call me Katsuraki!" Katsuragi said slowly, "I want to learn about the AR device you're working on right now!"

"You mean 'Augma'!?" Shigemura didn't seem surprised, or he guessed it when Katsuragi contacted him in the first place using KAMI, but he didn't expect it to be Katsuragi.

"Well, that's right!" Katsuragi nodded, although he had the 'World Seed' left behind by Akihiko Kayaba, as well as the previous SAO data, it didn't mean that he could ascend to the sky in one step and create what he wanted.

Science is rigorous and mutually reinforcing, and Toru Shigemura is the supreme authority on brain-computer interface (BMI) projects in Japan for non-invasive (no biological harm) research, and his research is definitely worth learning from.

"The biggest problem with complete stealth is that the function itself is completely stealth, and VR games are all virtual reality, which is too risky to predict. ”

Shigemura Tetsudai looked at Katsuragi and said flatly: "Although complete stealth is not only a game, but also communication, browsing, information production, etc., but most of the use is only touch and vision. ”

"So in my opinion, it's inevitable to eliminate the completely stealthy method and use more secure AR devices, including games!

Katsuragi looked at Teru Shigemura in front of him seriously, and he couldn't deny that some of the other party's words did make sense, but that didn't mean he completely agreed, especially in terms of games.

If it's really as the other party said, Lanzi and Yuki will be excluded in the first place, with their bodies, they can't complete the game experience in reality at all, and compared to complete stealth, enhancing the real game experience, it's definitely two completely different feelings.

"Maybe!" But Katsuragi's purpose this time was to study the other party's technology, not to discuss the question of who should be eliminated more than AR or VR, so he didn't refute Shigemura's inquiry.

"So Professor Shigemura, to what extent has you studied this product!?" Katsuragi looked at Toru Shigemura, who was sitting opposite, and said in a deep voice: "Maybe our company can have some cooperation with you!"
