The truth summed up by the ancient Chinese is absolutely golden, and it only depends on whether future generations can understand it.

"There's no way out, but I'm relieved." Donna's expression became calm and resolute, "What people want in this life is not length, but quality, and it is also a very pleasant and grand thing to be able to go through a reckless journey with a person who is worthy of living and dying together." ”

Lin Xuan nodded: "I broke the cauldron and sunk the boat, but I found a chance to win in advance in a desperate situation." ”

He was still staring at the dark river that couldn't even float with strips of cloth, and secretly sighed at the miracle of nature's creation. The strangeness of this quicksand river is that the sand moves with the water, and the river water is mixed with extremely fine floating sand, and the water and sand are always indistinguishable and mixed together, forming an effect similar to the desert quicksand. The sand particles break up the buoyancy of the water, and once an object falls into the water, it is instantly captured by the sand particles and sinks to the bottom under the action of gravity.

"With the 'Quicksand River' and the 'Flaming Mountain', what can you encounter in the end? Will you sink to the Yama Underworld, or will you become a Buddha in the Western Sacred Mountain? Lin Xuan asked himself with a wry smile.

"Let's go?" Donna asked.

"Let's go-" Lin Xuan turned around, holding Tang Na in one hand and pointing into the distance with the other, "Go and see what kind of world it is!" ”

After about half a kilometer, the cave suddenly opened up and entered another wide space.

Lin Xuan looked up, although he couldn't see the blue sky and white clouds, the top of this space was a complex overlapping structure, like dogs and teeth, and the sky light could penetrate between every two floors. Therefore, he was able to breathe in the fresh air unique to the snow-capped mountains, and his spirits were immediately refreshed.

The space is hundreds of meters wide and has a ceiling height of more than 50 meters. As a rough estimate, the height of the two overlapping layers is 10 meters, and it can be seen from the level of skylight that the structure is not less than 10 layers.

Lin Xuan silently calculated: "If this place is a hundred meters away from the surface of the mountain, it should be located in some undiscovered Grand Canyon. With humanity's own ability to climb, the chances of escaping from there are too slim. However, it is good to be able to breathe real air after all, and it is finally possible to breathe through it. ”

The so-called "breathability" he thinks of refers to geographical space and the long river of time.

"Woohahahaha, woohahaha......" A strange laugh came from the front.

"Is it Luo Yuan?" Donna screamed alarmedly.

Lin Xuan could hear that it was indeed Luo Yuan's voice, but it was a little different. Before, Luo Yuan's voice was low and dry, obviously an ordinary person with no internal foundation, but now it was different, every burst of laughter reverberated in this vast space, as if it had been amplified by the top square sound.

In all fairness, even if Lin Xuan laughed with all his might, it would be impossible to produce such a shocking effect.

The only explanation is that Luo Yuan had some kind of adventure, and in a short period of time, he turned from an ordinary person into a super master with unfathomable internal strength.

When the brave wins on the narrow road, Lin Xuan has no choice, and immediately takes Don Na's hand and rushes forward.

The ground gradually rose, and when they reached a huge "threshold" shaped stone embankment, Luo Yuan's laughter suddenly stopped, but the humming echo was endless.

The stone embankment is about two meters high, stretching more than 100 meters from side to side, and is carved with intricate mysterious patterns.

"It's a kind of text...... It's a mixture of ancient Tibetan and Sanskrit, I can roughly read it, and it should mean ......" Donna hesitated, and walked slowly to the right.

Lin Xuan put his ear to the stone embankment and listened calmly, not affected by those patterns in the slightest.

There was no sound outside the stone embankment, and the previous sounds seemed to have been cut off by a steel knife, and they could no longer be heard, and it completely became a dead and silent world.

Lin Xuan had a strange feeling, just like sometimes he looked at an old-fashioned grandfather clock that had stopped, once the spring of the grandfather clock was released, the hands stopped, and all kinds of noises inside the machine disappeared, and the machine changed from a "ringing and moving" living thing to a dead thing. From life to death, it is only a second or even half a second apart.

From this, he thought of the stone sculptures outside the cave, weren't they also the table clocks that had stopped?

The stop of the grandfather clock leads to the stop of time, and conversely, the stop of time leads to the stop of the clock. So, what is the disappearance of the qiē sound? Could it be that the "clock" that controls everything on the earth has also stopped?

Lin Xuan shook his head and reorganized his thoughts: "The rotation and revolution of the earth are a precise and constant state of motion, which is more accurate than the famous watches of any country on the earth, so the earth talents specially set up the Greenwich Observatory to measure and track its trajectory, and set the Greenwich Mean Time to demarcate the standard time for clocks in various time zones around the world. In this way, the rotation of the earth produces the time of a day and a night, and the revolution produces a year, just like the song "Love You for 10,000 Years" sings——"

The singer who sang that song was a Hong Kong singer that Lin Xuan loved very much, and every time he listened to that song in the past, Lin Xuan's heart was touched.

"If the earth stops...... What would happen if the Earth's axis came to a standstill? Lin Xuan asked himself in a low voice.

The Earth, like the other eight planets in the solar system, rotates around an imaginary axis of rotation while revolving around the sun, which is the rotation of the Earth.

Rotation refers to the rotation of a celestial body along an axis that passes through itself, which is called the "axis of rotation". The Earth's axis of rotation is at an angle of 66.34 degrees to the ecliptic plane, and it crosses the Earth's center of mass. In the same way, satellites, planets, stars, and galaxies all have zài as a form of motion. The time for the Earth to rotate is 23 hours, 56 minutes and 4 seconds, and the time for the Moon to rotate around the Earth is the same as the time it takes to complete one revolution around the Earth, which is 27 days, 7 hours, 43 minutes and 11.5 seconds.

If the rotation stops, there will be no zài for that time on the planet.

It is conceivable that after the earth's rotation and revolution are all gone, it will become a "death star" in the universe.

The word "Death Star" comes from the famous movie "Star Wars", two years after the release of the movie, the "Voyager" spacecraft flew to Saturn, and when the spacecraft sent back pictures of Saturn's moon "Titan", everyone who saw the photos was shocked, because Enceladus is very similar to the Death Star in the movie. Enceladus' diameter on the major axis is 185.5 kilometers, which is not much different from the preset size of the Death Star in the movie.

Herschel crater on Enceladus is nearly one-third the diameter of the moon, making it the largest crater in the solar system in proportion to the planet, with a crater edge as high as 5 km, some craters as deep as 10 km, and its central peak 6 km above the bottom of the crater. If there were an equal proportion of impact craters on Earth, it would be 4,000 kilometers in diameter, more than the width of Canada. The impact event that formed the crater nearly smashed Enceladus to pieces, and the fractured terrain was still clearly visible on the opposite side of the crater, caused by the shock wave that crossed the star after the impact.

"The Death Star? Dead Earth? If the 'big killer' can cause a huge lethality like the Herschel crater impact incident, then the earth will also be broken by the waist and eventually fall ......apart," Lin Xuan frowned, because after too many scattered events were penetrated, the outline gradually became clear, and finally pointed to the terrifying proposition of "Earth Destruction".

Of course, the earth may have experienced a similar "impact and self-explosion" event a long time ago, because as early as August 29, 1984, American scientists proved the "continental plate drift theory".
