Since there is no harvest from the retreat, there is no point in sitting in the mountains in a daze.

"Hey"

Putting away the enchantment, Lu Xiao teleported to Yongzhen's side in the next second.

At this time, Nagama was still visiting the Fushimi Inari Taisha Shrine and was walking past the famous Senbon torii gate.

Lu Xiao, who suddenly appeared beside him, surprised Yongzhen: "So fast? What were the results of the retreat? ”

"Completely fruitless."

Lu Xiao shook his head helplessly: "The consolidation of the realm is going well, but I can't find the inspiration for a breakthrough." ”

"How so?"

Yongzhen was a little stunned: "Didn't you say that after obtaining S-level skills, you can speed up the progress of stepping into the Divine Domain?" ”

Lu Xiao smiled bitterly: "I don't know, maybe I'm in a hurry, and I don't have enough understanding of the power of time and space." ”

"Hah"

Fenrir yawned and rubbed against Lu Xiao's leg to greet him in this way.

Squatting down to help Fenrir's chin scratch the itch, Lu Xiao sighed: "Forget it, just like Consus said, let's relax in this world." ”

"It's fine."

Yongzhen took Lu Xiao's hand and continued to move forward: "Fushimi Inari Taisha is the finale of my visit to Kyoto, and after that, let's go back to Tokyo to find Xiaoyu, I don't know if she has encountered anything interesting over there." ”

Lu Xiao rolled her eyes: "What other interesting things can there be in the virtual world, does it matter if you can't get out of the game?" ”

……

Fushimi Inari Taisha is an ancient shrine dedicated to the god Inari.

Inari is one of the most popular shrines in Japan with the highest incense burning, and is one of the most incense-burning shrines in Japan, where a large number of pilgrims come every year to pray for a good harvest, prosperous business, and abundant wealth.

After accompanying Yongzhen through the Senbon torii gate, the two and one wolf have arrived at the top of Mt. Inari, and from a high vantage point they can overlook the main building of the shrine below.

Lu Xiao looked at the shrine below and closed his eyes to feel it.

Sure enough, there was no breath of any gods.

"Well, satisfied!"

Yongzhen stretched his body comfortably: "Okay, don't think about it so much, let's go back to Tokyo." ”

"Maybe Xiaoyu can make some suggestions for your situation."

The corners of Lu Xiao's mouth twitched: "I hope she didn't become a waste fox when she wasn't addicted to virtual games." ”

Contrary to Lu Xiao's expectations, when he teleported to the target location according to the coordinates in front of Yuzao, Xiaoyu actually did not enter the game, but sat on the sofa and frowned in a daze.

"Virtual World...... Can it be considered a world that exists independently? ”

The broken thoughts in Yuzao's mouth made Lu Xiaoleng pause, and the inspiration that he had been looking for before finally flashed.

Yongzhen didn't notice Lu Xiao's situation, she stretched out her hand and shook it in front of Yuzao.

"Xiaoyu? What are you doing? ”

"Huh?"

Before returning to the god of Yuzao, I found that Yongzhen and Lu Xiao had come back at some point.

"Huh? Why did you come back so soon? Isn't Lu Xiao going into retreat? ”

Yongzhen shook his head and said, "He said that if there is no inspiration, we will ......"

Yongzhen, who turned around, found that Lu Xiao was standing in place, and his spirit was a little trance.

“…… Inspiration? ”

Tamamo nodded: "Maybe, it's hard to say about inspiration, and I haven't been able to catch the key to breaking through the Nine Tails." ”

Having just returned to the villa that Tamamo had bought, Fenrir fell asleep on the ground again.

"Here we go again."

Yongzhen shook his head helplessly, ignoring Lu Xiao who had settled down for the time being, and half-squatted beside Fenrir with Yuzaoqian, carefully absorbing divine power from its body.

After about a quarter of an hour, Lu Xiao finally woke up from his contemplation.

"I've got a way!"

Pacing in the room by himself, Lu Xiao said with words in his mouth: "Assuming that the virtual world is also a special space that exists independently, if I can enter it in the flesh and feel its special rules, maybe it ......."

“…… Ha? ”

Yuzao looked at Lu Xiao in amazement: "You want to enter the virtual world in the flesh?" Your brain doesn't ...... Wait a minute. ”

Tamamo had been thinking about this before, and she had a premonition that her fate was in the virtual world.

But not the virtual world of SAO.

"Hmm"

Yuzao squinted his eyes and thought about it for a while, and when Lu Xiao came back to his senses, he asked, "Can you let us jump directly into time in this world?" ”

"Yes." Lu Xiao looked at Yuzao in confusion: "Which time do you want to go?" ”

"Three years later."

A gleam flashed in Tamamo's eyes: "The time when the underworld world was secretly built." ”

“underworld……”

Lu Xiao listened to Yuzao's request and suddenly showed a sudden expression: "I see, the world where there is really an artificial soul, where is your chance?" ”

Underworld is a world secretly formed by the Japanese government in order to develop highly intelligent unmanned weapons, and they want to cultivate artificial intelligence with human-like thinking in this virtual world.

This is the alicization plan.

Lu Xiao had been a light of Sword Art Online before, and had a relatively in-depth understanding of the alicization plan.

To put it simply, the quantum calculus core left behind by Akihiko Kayaba captures a strange existence called quantum light.

After secret research by scientists, it is generally believed that quantum light has a structure extremely similar to that of the human soul.

This discovery inspired Japan's top brass, which did not have military power, to circumvent the defeat treaty in World War II by creating highly intelligent unmanned weapons.

The NPCs of the Underworld, referred to as UW, are completely different from SAO, GGO, and ALO.

They are by replicating the newborn baby souls, converting them into quantum light shaking light and putting it into the UW world, and then using the time scale acceleration technology of SoulTranstorstl to speed up the time flow rate of the UW virtual world, so that these baby shaking lights can grow up quickly under the guidance of the official staff.

But just as they were about to reap the results, Seijiro Kikuoka and Ken Higa, who were leading the experiment, discovered a problem.

When the inhabitants of the UW world learn that they are copies of someone else's soul, they will invariably fall into self-doubt and confusion, and eventually their shaking light, or artificial soul, will collapse.

Again, human beings are selfish, and everyone wants to be a unique being.

When one day they learn that they are just copies of someone, it is only natural that there will be wavering and self-doubt.

This is one of the reasons why human cloning is officially forbidden to exist in various countries.

The fate in front of Tamamo may be related to the human soul, and even she herself can't say why for the time being, so she can only have a rough premonition that her fate comes from the UW world.

It is not so easy to send the physical body into the virtual world through spatial teleportation, there is a dimensional wall between the two worlds, and it is equivalent to a three-dimensional person who wants to enter the second dimension, and can only succeed by humanizing his own piece of paper.

Breaking through the dimensional wall, Lu Xiao thought that this was the last task before he stepped into the divine domain.

Being able to freely enter and exit the two-dimensional world from the three-dimensional dimension means that Lu Xiao can also step from the three-dimensional to the higher fourth-dimensional, or even fifth-dimensional, and the degree of control over the power of time and space will make a qualitative leap as a result.

Lu Xiao had no way of knowing what the fourth dimension was like, and it was naturally impossible to comprehend what he didn't understand.

UW is a different virtual world, at least Lu Xiao can understand its principle of existence, and have the opportunity to touch and experience it directly, so that he will not be clueless.

After clearing his thoughts, Lu Xiao regained his energy.

"Tell me when you're ready, I'll ...... at any time"

"Wait."

Yongzhen suddenly raised her hand to stop, and she pointed to Fenrir, who was still not in good shape: "Before we go, we'd better solve Fenrir's problem first." ”
