Perhaps life in the wasteland is too cruel and indifferent, and even the people from the world where biochemical weapons run around are physically and mentally exhausted, and they spend more time recuperating here than expected...... However, Leon and Ada still have to go back after all, and Leon's words are naturally to report back to the U.S. government, as for Ada, well, even Leon doesn't know whether she is a free person with no affiliation or a senior employee of a mysterious organization, so he can't predict what she will do.

But

“…… Are we leaving, too? ”

"...... Leeds?"

There seemed to be more than two of them leaving the Overworld.

"Don't get me wrong, Brother Bing, I'm not trying to drive away you, a teammate who can't be crooked, the most enthusiastic in fighting, and the most diligent in building," such a teammate left and didn't know where to find another one, "Villager A is the same, if there is not even one villager in the main world, the materials during the time I went to other worlds will be wasted~"

"What the hell is ......?" Manola breathed a sigh of relief, and since she noticed that even her father was looking at her with many strange eyes, she knew that only this world was the best place for her.

"It's just a matter of timeline," seeing that everyone didn't understand it very well, Liz had to explain from the beginning, "You already know that there is no exact time relationship between the other world, right?" ”

"Well, it's better to say that in the science fiction novels I read, I always feel more strange that there is an inevitable time relationship between the two worlds." If it's the setting of 'the human world' and the 'underworld', which sounds like 'everyone is a complete world together', it's okay, but if you look at the biochemical world and the main world, even the laws of physics are different. Everyone knows that there will never be a direct connection between the two, so why should there be a necessary time binding?

Ida nodded. "Listen to Leon, you call this a 'jump crossing'~"

"Hmm...... But what I'm going to say is. Liz clenched her hands into fists and made a 'separate' gesture in front of her, "The flow of time in each world is one-way......

“？”

"For example, as the captain, I don't want you to mess around while I'm having fun alone," even teammates won't allow this kind of thing to ruin their game, "so the earliest time you'll be able to return to the team will be the next time I'm in the Overworld...... Write it down, this is the timeline of the Overworld. ”

Leon nodded, realizing that this was not just an 'example'. Leeds' personality really doesn't let them mess up the journey that was originally going well, and Ada's entry into the team was due to his early greetings.

"And for you, whether you want to come back that day, a month later, or a year later, as long as your thoughts are pure enough when you 'pray', you should be able to return to the Overworld when I 'stop for the next time'...... This is the timeline of your world. ”

"......" Leon shrugged.

"So the question is, what if Manola wants to go home to see her dad when you come back? In the eyes of her, who has always remained in the Overworld. Time had only gone for a few days, and she prayed for the same amount of time to 'your world......"

"The Paradox of Time...... Is it? ”

"It's not just a temporal paradox of 'future' changing the 'past', it's an otherworldly version of the temporal paradox...... Interesting~"

Others finally understood what Liz had pointed out.

But it's up to Leeds to conclude the example: "Yes, Manola has seen it all of you in a few hundred years." If she goes to the world where there is 'you hundreds of years ago', then it is obvious that she will enter the time paradox of the 'future' of the single world and change the 'past'......"

“…………”

"Of course, this kind of time paradox doesn't happen in my world." Liz interrupted everyone's thinking with a smile, but the smile was a little narrow. "Because in this case, Manora can only travel hundreds of years from the beginning, especially after you leave that world. It's perfect~"

“！！！” Perfect fart, two hundred years later, other people's fathers will have no bones left!

All in all, does that mean that other people's timelines affect their own?

"This kind of question will be useful in the future, but it doesn't really matter unless the four of you are from the same world...... Just look at me, can't I just go to your world if I'm fine? Or even if two hundred years have passed in your world, I'm just sorry that Shirley, Claire, and Hindrance Pear have already received their bento boxes before I knew it. "Who knows if they died unexpectedly or if they lived happily ever to old age?

Liz put away her smile and said seriously, "What to say, I don't want you to suffer a tragedy for this reason, so I suggest you follow them...... My gut told me that the two of them couldn't get out for a moment. ”

"Wait, don't tell your inexplicably precise intuition!" Leon was already worried, and Leeds was really worried about an ambush when the U.S. government met.

"Haha, the agent who has returned from another world, this kind of thing can't be avoided~~" Liz smiled, he didn't carry this pot, the person who chose to follow him instead of letting Liz quietly kick himself out of the permanent team was Leon himself, "As for you ......"

“………… I said to my dad and came back right away. Manola lowered her head and said her decision.

"It's good to decide for yourself~" Liz didn't comment, turning his head to look at the silent Klausa.

“…………”

――――――――――――――――――――――――――――――――――

As a result, Krausa also returned to the biochemical world, of course, he did not need to report after resigning from his military position...... He's planning to find a wife and son, right?

said that he abandoned his wife and children for a new ideal in life, but in fact, his ex-wife was unwilling to go with him, and the abandoned party could even be said to be Klausa's side, so he still loved his ex-wife and son a little.

Kraussa doesn't quite believe that Leon and Ada will take the initiative to trap them in this world for a long time, but he also has the same opinion as Lez, sometimes it is not like you can go, and he does not want to lose the opportunity to see his son because of the accident that happened to Leon and Ada, although he made up his mind at the time of divorce and never looked back.

"Day after day, it's only the two of us left~"

"Wang~!" He barked heartlessly every day, completely different from the low whimpering that the dog meat had been whimpering when it was taken away by Leon.

"Haha, I'll take you out to another world to play later, now ......" Liz suddenly pulled out a few pieces of paper, "While no one is watching, I'm going to complete a few big projects that will surprise people!" (To be continued.) )
