We have a level system in place for mankind.

After defeating the alien beasts of the Giant District, we took a look around Ye Su City.

There is no longer a definition of the territory of foreign beasts, but since there is an environment that is easy to live in for foreign beasts, many foreign beasts have moved into the mountains and forests.

However, even where it was a city, the buildings have collapsed and turned into a forest with trees. Moreover, it was not an original tree, but a mutated tree.

Small animals and wild animals such as boars, deer, and bears have also increased rapidly, and seem to be feeding on aliens. The breeding power of rabbits was particularly high, and they were frequently seen in Ye Su City. It seems that the rabbit, which was kept by pets, has become wild.

It feels like the ancient Earth has been restored, but the alien beasts, who lost their guardians in battle with each other, seem to have begun to act entirely on their instincts.

The surviving Cyclops were scattered as soon as the Guardian died. Aliens are likely to be the majority of extinct species, but some will survive and settle on Earth.

Kojiro, the only remaining Guardian is the Guardian of the Demon Ward, what should we do?

"I don't think that Guardian is going to break the transfer dome." Defeat the Guardian at that time. I'm tired today. "

Kawai also nodded. We went back to Yashiro and headed home. Children's voices can be heard from a nursery school near home.

My house is located near the center of Yashiro, so the number of nursery students and nursery teachers is increasing.

The log house has a large garden with many fruit trees. It was planted at a time when food was still insecure.

They include persimmon, raspberry, olive, and biwa. These fruit trees originally existed in the food area, and although they differ in appearance and color from those found on Earth, their taste for fruit is similar. It is conveniently called by the same name as the fruit of the earth.

When I entered the house, Mecca and Coletica were doing their homework at school.

Welcome back.

"Welcome home."

Elena's voice comes from the kitchen. I hear you're preparing dinner. When Kawai and I sit on the sofa, Maka brings her homework.

"Brother Kojiro, tell me this."

Which one?

It was an elementary school student's problem, so I managed to answer it.

Agarta thinks it's peaceful, but he remembers what Japan is like. I don't think that Japan, which has become a house of alien beasts, will return to its former world.

Kawai also ate together and then went home. The kids went to bed and started talking about me and Elena being the only ones.

What happened to Ye Su City?

“The buildings are falling apart, and the land is starting to become a forest. We'll be back in the woods in a few years."

Elena looked lonely.

“When will we be able to live again?”

"Scholars say that it will be thousands of years sooner or tens of thousands of years later. It seems that the poison in the air will be purified."

Because the poison hinders the health of pregnant women and makes it difficult for them to become pregnant, the humans remaining on the planet will be extinct.

“What happens to people in countries that don't have unrestricted crystals?”

"We are discussing this with the United States, but there is an opinion that Japan and the United States will provide those countries with unrestricted crystals."

However, if the alien beast is destroying the transfer dome, isn't it not enough to provide unrestricted crystals?

"That's right, but we can't protect you." Even if they survive, they may not return to Earth. ”

The baby cherry began to cry in the children's room. Elena gets up and goes to apologize for the baby.

When I was alone, I thought about how many transfer domes I needed in Japan. I couldn't protect all of them, but I wanted to secure about twenty of them.

The next morning, when I went to Misaki, I thought about it with a difficult face.

"What's the matter?"

"The alien beasts started destroying the transfer dome all over Japan." That's why I needed a team to protect the transfer dome. "

I told Misaki what I thought yesterday. [M]

I see, the priority is to protect the 20 transfer domes that I think are necessary.

“Yes, that would be less of a burden.”

"As a result, the remaining metastatic dome becomes extremely small."

When Misaki tried to return to Japan in the future, he thought it dangerous to have fewer transfer domes in the passage.

Once you've dispersed your forces, you won't be able to defend what you can defend.

When I said that, Misaki sighed and nodded.

“You're right. I know, but I'm worried. The Mofabar tribe has prepared a food area for us, but like a tyrannical landlord, I don't think we should tell them to leave right away.”

"The time concept of the Mofabar race is different from ours. If you say right away, it could be a hundred years from now."

When I asked Commander Rebius of the Mofabar race when I would be able to live on Earth, he told me that he would wait a moment, but that he would come back. Wait a minute, it's going to be tens of thousands of years ahead.

But I wonder if it's okay. Some alien beasts have giant beasts that are over 10 meters in length.

I'm starting to get a little worried. Can you defeat it with the [Plasma Cannon] or [Dark Phase Cannon]?

At that time, I remembered the three-dimensional crest of "Charged Shot". It feels like a three-dimensional sigil used in combat, but I don't know how to use it.

I tried to throw some force into the sigil structure made from this three-dimensional sigil, but there was no response. It seems that the energy used is different.

After talking to Misaki, I went to the 3D sigil lab. There, several researchers are working on a three-dimensional crest. Among them, I went to the Nakagawa researcher who was studying the three-dimensional crest of "Charged Shock".

Nakagawa-san, did you find anything out?

"One thing. The word 'Ecurel' appears in the 'charged strike' material, but the same word also appears in the three-dimensional seal called 'Myriad Core'."

The three-dimensional sigil of "The World Core" is like something that generates a lot of energy, but I didn't know how to use it.

It's the 'Myriad Core', and it's a strange three-dimensional crest.

The crest structure is ready, do you want to see it?

"Oh, let me see."

When I looked at the sigil structure of the "World Core" that Nakagawa researcher showed me, I was connected to the knowledge of "advanced knowledge (three-dimensional sigil)" engraved in my brain.

I understood how to use the 'Myriad Core'.
