According to historical records, when Mount Vesuvius erupted, the hot ash engulfed Pompeii, a full 10 kilometers away, in the blink of an eye.

If the heat of the Earth's outer core erupts, at least half of the Earth's surface will be in flames. Geologists predict that if the gravitational forces of the tide do such deadly damage to the earth one day, the breakthrough will be in the depths of the ocean. ”

In short, at the end of the 22nd century, human beings can neither go to the sky nor the sea, and they can only dare to move on land.

Wedell said wistfully: "Life on earth that evolved from water can no longer listen to the sleep song of the waves at night. The sea has become a forbidden place in the human imagination, and they only want to stay as far away as possible. ”

"Sleep Song of the Sea......

Hai Ge's heart trembled slightly. The life before the age of three was like a faint shadow, he couldn't see the content of the shadow clearly, but in this life, he could no longer wave it away.

"But I can go to sea." He said that he had no fear of the theory of the eruption of the Earth's core, "The Fire is the only stronghold set up by the Redeeming Light Organization on the surface of the earth, and I must be optimistic about this stronghold!" ”

"Don't worry, kid, the earthlings' worries about the ocean are just unfounded." Wedel raised his hand and said nonchalantly.

"What do you mean by that?" Hai Ge was stunned.

Wedel looked into the distance and said, "The underground plant kingdom is located in the inner layer of the earth's core, and in the outer layer of the earth's core, there is indeed a hot substance, you have known this for a long time. ”

Haige nodded.

He continued: "But those who think that hot matter will erupt on a large scale due to the gravitational force are ignoring the element that, in the absence of this element, the outer core of the earth will remain in a stable state and will not be directly affected by changes in the earth's surface unless the earth is turned over." ”

"Oh? What is this element? ”

"It's a reaction force equivalent to the gravitational force."

"Reaction force?"

"Yes, it is the relationship between action and reaction that the earthlings call Newton's third law. Although invisible to our naked eyes, it is undeniable that whenever a tidal force acts on the Earth, the Earth gives it back an equal reaction force. The Earth is tidally locked, not because the reaction force given is insufficient, but because its mass and volume are much smaller than that of the Sun. For the Sun to extend the power of the gravitational force all the way to the Earth's core, that force would have to be at least three to five orders of magnitude greater than the current force, and it was clear that the Sun could not do that. What's more, it is also being dragged by the adsorption force of the black hole of the U star, and a large part of the force is dispersed over there, so how can it have the strength to extend its claws into the center of the earth? So I came to the conclusion that the seas on Earth are absolutely safe, and the airspace is the most dangerous place. ”

"I see!" Hai Ge listened convincingly.

Wedell chose the sea as the launch base for the Hoiren, not only because he longed for the mysterious sea, but also because the ocean was safe on Earth on the brink of destruction.

As soon as the conversation changed, Wedel warned Hai Ge.

He adjusted the chart on the electronic display to the Pacific Ocean, so that the glass facing them was covered by the Pacific Ocean, and Haige could even see the trees on the islands in the sea, or the reefs scattered on the shore.

Wedel's hand was pointing at the islands, too.

"Son, do you know how many islands there are in the Pacific Ocean?"

Haige shook his head.

"There are more than 20,000 islands and islands in the largest ocean on Earth," Wedel said. If they are connected, the measurable area can reach 4.4 million square kilometers. My advice to you is to stay away from those islands, and once you're in the ocean, never go to land again until the Hoi is dragging Earth out of the solar system. ”

"There are so many islands, can't I go up to one?" Haige was immediately disappointed. When Wedel reported the number of islands, he was quite happy, and secretly thought that if he was bored on the boat, he could at least find a deserted island with no one to pick some wild fruits or hunt a few small animals, or even lie down on the grass or the beach to sleep beautifully.

Wedel ruthlessly shattered his dream: "Although the Pacific Ocean is vast, there are no desert islands, every island is occupied, as long as you leave the high seas, you will definitely be drawn into the war of mankind, and you will never return to the Fire Man." So, never leave the high seas! ”

Hai Ge stiffly memorized Wedel's words in his head, but in fact, he was secretly thinking to himself, if he found traces of those people in the wolf's den on the battlefield of the Arctic Circle, would he really be able to hold back and not leave the open sea? When he thought like this, the hatred that had disappeared for a long time crept into his eyes again, and his eyes, which shone with happiness, became fierce again.

Wedell pretended not to see anything, and zoomed in on a point on the chart, which showed Burketown, Australia, and Mornington Island, facing Burktown.

He pointed to Mornington Island and said to Hai Ge, "This is where we are now, and this is where the Variable Star 1 spacecraft made a forced landing after passing through the Earth's atmosphere. ”

"Seventy years ago, the first stop on Earth was Australia and not China?" Haige asked in surprise.

Weddle replied, "Yes." Through the navigation map, I saw that there was a large desert in that country, so the temperature was very high. The bottom line is that only indigenous people live in the desert, and the high-tech cities inhabited by humans are far away from the desert, a huge ring that encloses the desert, as if the area is protected. This kind of geographical conditions are undoubtedly the most ideal for me, so I chose there. ”

Haige had never been to Australia, and to be honest he had never left his country, but he had heard that there were still many indigenous people there who had maintained their primitive lives. Another name for the natives is barbarians, so don't they be embarrassed by the uninvited guests who suddenly fall from the sky?

"Absolutely." Listening to Hai Song's question, Weddle replied, "As a hundred years ago, the indigenous people of central Australia lived in tribes and had friendly relations with each other, but there were many times local wars. They have always lived in semi-isolation, but they have long ceased to be barbarians in straw skirts and sticks. In many places, modern communication devices can be seen, and in some tribes, robots are used to assist with farming and harvesting. The weapons they used were no longer just spears with stone knives or flying instruments, but the custom of exchanging messages in mute while hunting is still preserved today. With the changing times, more indigenous people have left the desert area and entered the city to work, study and live, and have made a name for themselves in different fields. ”

Hai Ge smiled and asked, "It seems that you know a lot about the life of the Australian Aborigines, I think you didn't leave immediately after the crash landing, but lived there for a while, right?" ”
