“…… The four seasons? ”

The moment she heard this name, Xia Xu's heart was filled with a nostalgic emotion, which made her heart seem to melt.

"What a name."

The name was so familiar that she could feel it even if she didn't remember it.

"Hmm. This is a name given to me by someone who is very important to me. ”

The four seasons gaze at Xia Xu close at hand, and even a vacuum cannot block the thoughts contained in words.

"I hope that I can take the place of my departed companions and experience this colorful world with four seasons."

"We really know each other, right?"

Xia Xu raised her hand and touched Shiji's cheek, and for some reason a sad expression appeared on her face at this moment.

"Hmm."

"I'm sorry."

Xia Xu whispered.

"I'm sorry, I have no memories of the past."

"Is that so?"

Shiki immediately accepted Natsuo's claim, perhaps because he also had amnesia when he first came to the Relay World, or maybe he felt that it was a good thing that that sad memories were forgotten.

"I see, please don't push yourself."

Shiki also reached out and gently stroked her face under Natsuo's surprised gaze.

"I'm very happy to see Xia Xu again."

It is the greatest happiness to be able to see each other again, although it is a sad thing to have no memories of the past, but they still have a future.

“……”

Xia Xu was stunned for a moment, then quickly retreated and turned around at the same time.

"Really, it's rude to call a lady by her name."

"Can't you?"

"No, you can't."

Xia Xu, who finally turned around, showed a wicked smile.

"And what should I call it?"

Shiki had a confused expression, and Natsuo seemed to be back to his usual state.

"Hmm...... Just call me sister. ”

"Sister?"

Four seasons thought about it for a while, and it was true that Xia Xu was older than him in terms of age alone.

"Okay. Sister. ”

“……”

"Huh?"

"I didn't hear it clearly."

"Sister."

"Do it again!"

"Sister?"

“！！！”

In order not to let Shiki see his face, Xia Xu turned around again.

(Oops, it's cute!) ）

"Is my sister okay?"

"Huh? No, no! ”

Looking at Xia Xu, who kept waving his hands, the four seasons were full of confusion. It turns out that Xia Xu is such a character?

"You're really a kid you can't be underestimated."

Xia Xu, who had regained his mood, quickly changed the topic.

"Let's do it first. There's still a long way to go. ”

"I see."

Shiki did not refuse Xia Xu's proposal, and the two flew together in the direction of the star.

There are not many things that can be done in the empty universe, and it just so happens that the four seasons can tell Xia Xu little by little about the past.

"That's what happened."

After listening to the narrative of the four seasons, Xia Xu sighed. She didn't doubt Shiki's words, perhaps because it was her own past, even if it disappeared from her memory, it would not disappear in her heart.

"Thank you."

"What?"

"The four seasons have kept their promises very well, and they have worked very hard to experience the world."

"Hmm."

Shiki smiled, perhaps this was the word he had always wanted to hear.

"I won't mention the past anymore, let's talk to my sister about what happened after you came to the relay world."

"Okay."

The four seasons did not refuse, and then elaborated little by little.

“…… That's what I've experienced in the relay world. ”

“……”

“？”

"It's nothing~~~"

I don't know why, I always feel that there are some strange ingredients in the smile that Xia Xu has been hanging on his face after listening to it. Shiki doesn't know if it's his own delusion.

The monotonous voyage continues, as if there are only twinkling stars in the endless darkness, but fortunately, Shiki and Xia Xu are very patient people, and they will not be bored by telling each other about their experiences on the way.

However, this does not mean that astronautics is an easy thing to do, and it is still a state of disorientation.

The danger of the universe being lost is self-evident, with all kinds of radiation, extreme environments, a plasma storm, a celestial collision, all of which can cause accidents. There are also energy-deprived environments in space. The starry sky looks like there are many stars, but they are tens of tens of thousands of light-years apart, and if you are in a low-density area, you may not be able to meet a single planet for thousands of years to replenish.

Even the Middle Circle Interferer is incomparably small in front of the universe.

In the course of the voyage, they are constantly correcting their tracks. After all, they don't have professional equipment in their hands, and it is easy to make errors, and the slightest difference in the universe will be lost by a thousand miles.

At this time, all the knowledge that the four seasons have learned in the past has come into play, by calculating changes in gravity, radiation, brightness, etc., to determine the location of stars. The size of the star and the likelihood of life in the galaxy were also calculated.

Based on the inference of the seasons, this is most likely a red dwarf, less than a quarter of the mass of the Sun. Because it is the star in its final state, it releases quite little heat. The chances of a living planet around such a star are not very high, unless they are artificially modified.

"The Four Seasons have really helped a lot."

During the analysis, Xia Xu also helped provide some calculation tasks, but the physics knowledge depends on the four seasons.

"That's all I can do."

If you are a scholar-type interventionist who takes the path of scientific and technological development, you will definitely know more things.

"It's already amazing. I remember that only one of the Adventure Guilds, known as the 'man at the top of the food chain', once tried to survive in the Middle Circle and finally returned to civilization on his own. ”

"That's pretty remarkable."

In fact, if you don't have professional knowledge, even if you don't encounter a disaster, you may just exhaust the last trace of strength in the universe and die.

Fortunately, they interferers have one advantage over the average human, and that is that the system can bring them back to the relay world. Once the time comes for the next mission to proceed, the system will bring them back, and they will only have to survive until then. And now that the four seasons are in the battlefield world, all the missions that fight the Dominator are not punished, and they will not be deducted from the corresponding reward points if they fail like ordinary missions.

But this is definitely the best policy, which means that they came here in complete vain. It is impossible to accept either the four seasons or the summer.

"Alas. It's a real failure to be calculated this time. ”

Xia Xu tapped his lips lightly, but there was no expression of loss on his face.

"If you are more cautious, you can really avoid it."

Shiki said bluntly.

"Yes, it actually made me so embarrassed in front of the four seasons, I can't do it if I don't get it back."

Xia Xu's slightly narrowed eyes flashed with a dangerous light. (To be continued.) )
