Lunch is over and discussions resume again.

"To conclude, the fusion of the world itself can no longer be stopped."

Best of all, Mr. Liberl cut it out that way.

"At the beginning of fusion, the two worlds are about to be reborn as a new one. If we try to force this apart, the two worlds themselves will collapse"

"So how do we stop the invasion of different worlds?

"Of course you have to fight and win."

"... what?

For a moment in that word, I get pounded.

No, isn't that inconsistent?

"Uh... Didn't I tell you there was no winning shot in the fight?

"Yeah, right."

To my question, Mr. Liberl answers normally without changing his complexion.

"Bye -"

"If 'immigration' takes place, to be exact, there's no winning - that's what I said."

……

"If it's before 'immigration' takes place, you guys have plenty to beat. Of course, we need to get ready down there."

……

I mean, what do you mean?

Mr. Liberl laughs at me tilting his neck.

This is it. It's a characteristic of someone who likes to talk.

The one who likes the roundabout and the far-flung way of saying it and doesn't try to draw any conclusions inside.

"... don't waste it, tell me."

"Of course, I'll explain it in proper order. First, before immigration takes place, an advance team of otherworldly people is supposed to come to the world."

"Advance team...?

"Yes, or a full-scale pre-invasion field investigation. Who would be anxious to be suddenly flown into a world they don't know about? To get rid of it, we're going to look into this world once and bring information back."

A reconnaissance unit?

Well, from the other side, naturally?

"I want you guys to fight them. If you win that battle, you'll see hope."

That said, Mr. Liberl took something out of his nostalgia.

It was a round crystal emitting purple light.

But I can understand at a glance that it's not just a crystal.

It's about the size of a baseball ball, but it feels intimidating as if it was relative to a giant monster.

Signs of breath swallowing also come from Ichinose sitting next to him.

"Is that...?

"Master key for performing interference with the system"

"Become...!

Everyone swallows their breath at that word.

It was just a super important item.

"With this, you can interfere with the system your master created.... but there are many constraints."

"Wait, wait. If you have such a handy item, how can you..."

"Why didn't you use it first? That's what you're trying to say, isn't it?

Mr. Liberl keeps blocking my words.

"I told you, there are a lot of constraints. It's not an easy substitute to use. It takes a lot of energy just to reassemble one system. Oh, you can't touch a candle, can you? Because if you touch it without putting up barriers, in an instant, you'll be sucked out of your life force (energy) and mummified."

"Huh..."

I don't seem to be joking.

Skills are still alarming against that crystal.

"... did the otherworlds rewrite the system with it?"

"Exactly - but not exactly."

……

"There are two master keys. One is the spare (spare) I have. And the original (original) is managed by the other person. The system was modified by the original."

"What the..."

You think there are two items that can interfere with the system?

Besides, I can't believe the other world has one...

"It's supposed to be an item to fix the bug. You really did something stupid for me."

Mr. Liberl tells me to throw up.

"I just don't have the energy I need anymore because I've altered it to be convenient for the other guys. So you can assume that they will never do anything more with their master keys."

Rest assured that only there, Mr. Liberl pushes caution.

"That also leads me to the reason I came here, but I'm going to need this master key in order for a different world to move into this world before 'immigration'. Without this, the other world will not be able to move into this world. I mean -"

"... you mean the advance party has that master key?

She laughs at me for saying things earlier.

"Exactly. If we can take that away, we can monopolize system fixes."

"Cheng Cheng, are you saying that..."

I can finally see the story.

If we can monopolize the modification of the system, we can stand in our favor even if other worlds invade us?

"There are limits to alterations, but we can still stop unilateral ravages. If done well, it will also be possible to take it to the first form of dialogue that the master wanted. Especially since it depends on you."

"Pfft, what are you saying? I just saw hope, but it's your word."

There was a grin on Mayor Uesugi's face.

Everyone else's dark expression only brightens up a little.

"So all we have to do is fight that advance and take the master key."

"That sort of thing. There are also restrictions on the transfer, so the number of people sent is precisely ten. I'm pretty sure they're sending them to the best of the best."

But she goes on.

"There's something in your favor, too. First of all, they don't know that you can use your skills to benefit the system."

"Really?

"Yeah, at the time they altered the system, I had some systems overwritten, too. Don't let them find out. That's making skills available to people around the world, and incorporating some original skills. It was tough to incorporate it unnoticed, but, well, they don't know everything about the system either, and I'm glad it worked out."

"Ah..."

So I remembered when I met her.

- "Four Skills" is a skill I created.

- I'm going to do everything I can to make sure these people survive a little bit... I wonder if it paid off a little to see you now or this place.

Is that what you meant when you first met me?

I wonder how much she did for us.

Not so long ago, I guess the deceased master was important to her.

As much as I want to inherit that will and make it happen even by betraying the people of my world.

"And the second. Where and when the advance party will appear. I can also predict this to some extent"

Mr. Liberl holds two fingers.

"The reason for this is because you defeated the 'Divine Tree' Peonie. Did you know that Trent is given the skill of 'alien assimilation'?

"Oh."

I snort.

There must have been a skill with that name that Chairman Fifty Storm used to ask me about when I appraised Trent's status.

Even so, at that point, it was a mysterious skill that I didn't know the details from looking into with the right to ask questions.

"In the world I was in, Trent was a monster with a large number and a wide distribution in the world. In fusion, as an adapter that connects this world to the other, the master gave Trent the skill of 'alien assimilation'. To spread widely around the world and build a network for the system.... Well, it's a skill that disappears from status if the world is fully integrated"

You mean literally 'rooting' the world?

"Hmm," The Tree of God "was particularly influential in that Trent. As long as it disappears, there will be some deflection between the two worlds."

"Is that okay?

"It's no problem. Even if the influence of the Divine Tree is strong, the number of other Trents is enormous. We can cover as much as we want."

Mr. Liberl continues.

"It's just that the effect will have some effect on the metastasis between the two worlds. The system tries to correct deflection, sending the flow between the two worlds to its center. So the destination is limited. I mean, the place where the advance party is sent..."

- You mean the town we were in?

"Exactly. If you're alone, you'll be able to adjust a bit, like me, but a ten-man transfer will definitely limit that destination. There won't be any energy left to regulate the area."

Oh, my God.

I can't believe that defeating Peonie would have such an impact.

... No, thanks to defeating Peonie, you should think you can take the lead on them.

"I found out where it came from. So when's that time of year? You don't think this is gonna work now, do you?

"It wasn't until Chaos Frontier entered the second phase of Continental Fusion that the advance party came to this world. I'm guessing from the system's operational status - maybe six months from now."

"Six months......"

It's the middle of June now.

I mean, is the showdown in December?

"It's the owners of unique skills who want to secure it as a force for war. And in order to make more use of your world's technology, we need to expand this area - the Safe Zone."

... That's a pile of things to do.

But I have to.

Do you think it would be better for the rest of the world?

"Oh, let's do it..."

"Um, we can't just let other people do this to us."

"Uh, I'll do my best, too"

"Haha, nagging, he said he was too nervous"

"Hey, Rich, don't make fun of me"

"Ha, Roppo is the same. Well, are you reliable at times like this?"

"Wow."

"Kew."

"... (sighs)"

Everyone gets up in a mood.

I'm just going to do everything I can to make things clear.

By the winter showdown, we have to have as much power as we can against the elites of the other worlds.

Restoration of modern technology. And owners of unique skills who are awake or will be awake around the world.
