Asuna sat with a blushing face, holding Zhang Yu's left hand tightly with her right hand. She put her head on Xiuning's shoulder and leaned on her left hand, holding his arm with her left hand.

"Taki, after you leave, only Shino and Yui are with me. At school, I met those friends who were originally in SAO, Kirito-kun, Celika, and Lizbet. But none of these can fill the void in my heart, do you understand?"

Zhang Yu also gently called Asuna's name.

"I understand, Asuna."

Asuna's face showed a well-behaved look, and she snuggled up to Zhang Yu like a bird dependent on her.

"I like you to call me Asuna, but in reality, call me Asuna."

Zhang Yu also showed a smirk on her face, and she gently pinched Asuna's tender cheeks.

"No, I want to call my wife."

"Ah, Yu, you like to tease me. Well, it would be great if you want Yui to be there too. But if she wants her to appear in front of us, you must break the obstacles between the imaginary world and the real world. Although the imaginary realm is becoming more and more ambiguous now, there is still a barrier to the difference in intelligence volume..."

After listening to Zhang Yu's words, Asuna remembered Yui again. So she analyzed the possibility that Yui had appeared with Zhang Yu, which was also one of the homework she had to do every day after Zhang Yu left.

Zhang Yu didn't understand what Asuna said, and looked at her in surprise and asked.

"Information miss?"

His way is to wait for the opportunity to create an artificial human body, or just find a way from the system that allows Yui to live in the real world.

Asuna held Zhang Yu's hand tightly, raised her face and said.

"Yes, for example, shaking hands like this at SAO is different from being in the real world, right?"

"Um……"

Zhang Yu nodded in agreement, and his eyes also fell on the overlapping and tightly clasped hands of the two. Seeing Asuna's right ring finger put the diamond ring shining with crystal clear light, her eyes softened again.

It turns out she has always been wearing it...

For example, the elasticity of the palms when the hands are attached is enough to dispel the body temperature of the cold winter, etc., are all touches that can also be found between SAO characters.

However, the sticky feeling of the skin sucking together, the friction of the palm lines, and the slight pulsation that the two people's blood synchronized are all the feelings that cannot be reproduced by the most cutting-edge complete stealth technology.

"Yes. But in the future, AmuSphere will evolve more and more, and what if the skin feeling and throbbing are completely revealed? At that time, can you tell whether it is a real hand or a game character's hand just by touch?"

"Yes."

Zhang Yu's unconsidered answer seemed beyond Asuna's expectations. She just blinked a few times without knowing what to say. But Zhang Yu stared at her pretty face and added a sentence.

"If you have Asuna, you can tell it. If it is someone else's hand, there may be no way."

As soon as he heard Asuna's hand temperature rise slightly, his whole heartbeat also begins to accelerate. Asuna's face turned slightly red, and she felt a little embarrassed. But she continued.

"It's not just the touch, but also the appearance, sound, taste, smell, etc., which are still quite high in the real world. So... Even if the AmuSphere is equipped with augmented reality function, you can know whether it is a real thing as soon as you see it or touch it."

Amplified reality function means using AmuSphere to combine realistic vision, hearing and digital intelligence in a waking state. As long as this technology can be implemented, current desktop PCs and mobile phones will be eliminated.

Because it can directly represent the imaginary operation screen in sight, you can immediately search for information and send emails, or even add navigation or intelligence tags to the road, which can be said to have infinite uses.

Now, mainstream intelligence machine manufacturing companies such as RECT are working hard to study the body. There are still many problems such as the movement of the body that will cause electronic pulse waves to lose focus or additional large-capacity batteries, so it is still a long way to go to practicality.

“…It’s a pity that some people say that the current helmet-type machines cannot achieve the popularization of amplified reality.

But one day we will find a breakthrough in technology. As long as we can also receive large-capacity five-sensory digital intelligence in the real world... or we can enter a complete stealth state at any time without the need for a bed and power cord..."

Zhang Yu nodded after hearing Asuna's murmur. He understood what Asuna meant.

What should be said is that AR can also be displayed in real life, but it seems that it is not combined with games yet.

Asuna looked at the beautiful and beautiful scenery in the distance, her eyes full of anticipation. She fantasized about the scene of herself running and playing with Zhang Yu and Yui.

"At that time, we will be able to transcend the barriers of the world and be with Yui forever. That day will definitely come..."

"Yeah, sure."

I will let you really see the living Yui, Asuna.

I promise.

Zhang Yu silently made a promise to them, mother and daughter in his heart.

In the past, when Ain Grant remembered his temporary separation Yui, they had also talked similar to what they had just said. Atuna, who noticed this, felt a warm current spreading in her heart, so she continued to lean her head gently on Zhang Yu's right shoulder beside her.

The vow that would meet her again was fulfilled two months later.

So what I said just now will definitely be realized.

The sunset approaching the winter solstice is simply hidden behind the woods in the west like a fall. The flock of birds preparing to return to their nests are flying in the bright red sky.

Hundreds of years ago, there was a castle on the vast grass in front of me, and the people living inside might also look at the sunset. And after hundreds of years, who would look at the red sky in this different world isolated from the torrent of time...

“…………………………………………”

Asuna suddenly felt a sense of nostalgia in her chest, so she sighed softly. Zhang Yu beside her looked at her slightly. The two of them smiled slightly after their eyes met.

"I seem to understand the reason why Shino wants you to bring me here."

"Huh...yes, is that?"

"Well. If the world is composed of a straight line of "time" and a plane of "space", then Tokyo..., that is, the center of our real world, is undoubtedly this place.

Then... Now the imaginary world that is constantly expanding because of "The seed", the central axis is the "castle" that no longer exists. Therefore, this kind of sunset scenery is so nostalgic..."

After listening to what Asuna said, Zhang Yu blinked two or three times, then showed a big smile.

"Yes... I said it too. Actually, I don't have such a specific idea. It's just... I learned something after listening to your speech just now."

"Huh, what's the matter?"

"It's the shape of Ein Grandet. That layer-based conical structure may symbolize the "timeline and space surface."

Asuna nodded slowly after thinking about it.

"That's right... maybe that's true. But in this case, the world that Kayaba Akihiko wants to create will become narrower and narrower, and finally the whole thing will be condensed and destroyed. However, his reservation was destroyed by a big explosion caused by someone in the middle."

The two of them laughed silently at the same time. After a few seconds, Zhang Yu took a strong breath, and then stood up from the bench with Asuna's hand.

"Then we should go back too. The park will be closed at five o'clock."

"Well. Next time I will bring Shino, Liz, Kirito, Celica and the others. It will definitely feel good to eat bento on that turf."

"That's right, wait for spring."
