We have a level system in place for mankind.

We return to Japan, transfer from Oshima to the food area, and fly to Yashiro. I entered Yashiro's government building and went up to the seventh floor where Misaki was.

Misaki seems to be busy when she enters the Chief Executive's room.

"Welcome home. How was Australia?"

"It's as planned." But they wanted to move to the food zone sooner rather than later. ”

Misaki stares at me. [M]

Didn't you threaten that the poison in the air was dangerous?

"I told you about the poison, but I didn't lie. I wonder if the Australians weren't aware of it."

Japan is mostly in a state of chains. Only the United States and Australia are in touch.

“What do China and South Korea do?”

"No, you shouldn't know that." If you knew, you'd think I'd help. There's not enough room for that in Japan. "

Misaki leaks a sigh.

"Well, that's right." Isn't it something that other states in Australia will notice? "

“Australia is a big country, so I think it will be fine for a while. By the way, is it okay to pay Australia for food?"

“Don't worry, agricultural production in Agarta is growing at an impressive rate.”

Misaki taught me that electric large-scale agricultural machinery was developed, and large-scale agricultural land development was carried out in Agarta, increasing the production of wheat and rice.

It seems that the production volume is about half a million people more than the demand of the surviving Japanese. You will pay the price for the resources that are dug up in Australia.

“It's like we're still going to have more farmland, but why?”

“It's a spare and livestock bait. I was to raise chickens, branded pigs, Wagyu beef and dairy cows in Agarta."

In Agarta, meat was said to be armored pig, but people who were not satisfied with it decided to bring livestock into the food area.

"It's a luxury." We slaughtered livestock that could not be kept in Australia. "

There was also an opinion that we should let it go naturally, but because it could destroy the ecosystem, we decided to kill it and use it as food.

"By the way, what about the research on communication using" source-rejection wave transmission "and" source-rejection wave reception "?"

I have acquired "Beginner's Knowledge (3D Seal)" and I am researching with Associate Professor Nozaki. While going to Australia, he uses two three-dimensional emblems, "source rejection wave transmission" and "source rejection wave reception", to develop communication means such as email.

Communication over short distances has been successful, and the first source-wave communication in Agarta was "Hello Yashiro". The source wave communication device developed by Associate Professors Nozaki is about the size of a cardboard box containing Mikan.

The reason for this increase is that the crest structure could not be reduced. We are working on miniaturization, but it has not yet borne fruit.

Incidentally, the current international communication is communicated using submarine cables, but since the submarine cable cannot be repaired, there is concern that it will not be possible to know when to contact it.

I am working hard to develop an alternative.

"So, what about the communication distance?"

"I tried to communicate about five kilometers away, but I was fine." Now I'm going to try to communicate at 50 kilometers. "

“It's a hassle. Try it once from the edge of Agarta.”

"That's impossible, isn't it?" It would be about a thousand kilometers. "

At that time, we thought that the source and radio waves were the same, so we underestimated the communication distance. However, I have been able to confirm that the output of the small source resilience output device is capable of communicating at a distance of about 800 kilometers.

In the future, it will be necessary to check how far the communication distance will increase due to the shape of the antenna and the power enhancement.

That said, if we develop a relay device, we will be able to secure communications with the United States and Australia. First, it will be necessary to establish a communication network between Agarta's city states. Since submarine cables have become impossible to communicate with internationally, it is good to say that such a thing has been developed and spread.

◆◆◇◇◆◆◇◇◆◆

After the Kojiros left Australia, the United States sent an investigation team to Australia. It was a regular survey team that was tasked with looking around American-controlled coal fields and mines and investigating recent developments in Australia.

When I first investigated Darwin, I noticed that there were more Chinese people. Carlton, the commander of the investigation team, frowns.

Captain, if you keep this up, Australia will become Chinese.

Sailor Chapman said.

"However, if you don't get the unrestricted crystal, you won't be able to leave the next generation." This place is going to die slowly. "

"Does the state not help?"

Captain Carlton shrugged his shoulders.

“When the poison released into the air was discovered, diplomats from around the world discussed it. At that time, the United States offered to cooperate and respond, but China and Russia refused.”

“Why?”

“I didn't like the idea of being American-led and responding. And it seems that the Chinese here have been abandoned by the mainland Chinese government."

It was the Australian and Japanese governments that took on the American proposal, but the Australian government gave up solving it on its own.

Europe tried to respond on its own, but there is a civil unrest that has erred in its response to the refugee problem. Only the United States and Japan say that migration is going well.

The survey team went around the coal fields and mines, and then checked out Perth Adelaide Melbourne. However, I have no plans to go to Canberra, the capital. The capital was a criminal city dominated by gangsters.

I heard rumors in Melbourne that the Canberras were beginning to move uneasily. Criminals in Canberra are planning to take control of coal fields and mines to take money and food from foreign countries.

Captain Carlton reported to his homeland using Melbourne's submarine cables. The information will be passed on from the United States to Japan, and the cozilos will also know.
