Lightning and thunder.

Storm and storm.

The heavy rain showed no sign of stopping, but it was getting heavier and heavier. The mudslides leaked from the top of the cliff became more and more fierce. The huge rocks wrapped in them were often hundreds or even thousands of tons, rumbling down, and the raised parts on the cliff bounced away, then hit hard on the slope below. The ground was trembling, and then rolled into the deep ditch, as if thousands of troops were galloping down, with an extremely terrifying momentum.

Yan Ruyu, who was already restless, couldn't sleep. The huge rocks that kept rolling down made a sound of the sky and the earth cracking, and she couldn't sleep anymore. She simply put on thicker clothes and crawled out of the tent and sat next to Han Xinghai to burn the fire.

"Can't sleep?" Han Xinghai asked casually.

Yan Ruyu nodded, held her elbows on her legs, held her chin with both hands, and stared at the burning bonfire with bright and charming eyes staring at the burning bonfire.

"Han Xinghai, will this cliff be smashed by a huge rock?" Yan Ruyu asked with a worried look on her face.

"The protruding rock is very thick, with a tight texture and a stable structure. It has been tested for thousands of years and will not collapse."

"What if?"

"If... if it appears, we will have to be buried alive." Han Xinghai smiled bitterly.

"Han Xinghai, do you still remember the magical door at the base of the river?"

"Um?"

"It would be great if we could have that door, and in this weather, we could summon that door, and then, open it, and go to a sunny beach, or a picturesque prairie, how wonderful it would be!"

“It may appear in a hundred years and a thousand years.”

"What do you mean is that humans can achieve it?" Yan Ruyu asked in surprise.

"Yes. In fact, that is also a leap in space development technology."

"What's the principle?" Yan Ruyu asked curiously.

"I don't know exactly, it should be a space technology similar to the space ring and the space button... The space ring and space button that place things are a stable subspace developed by humans, and that door is a passage for humans to find other places. I guess that the door is actually similar to the legendary teleportation array. As long as people walk into that door, they can reach the world that the door can go to..."

"If there is that door, wouldn't we be able to travel to any of the universe?" Yan Ruyu tilted her head and looked at Han Xinghai.

"Theory is, but the actual operation may not be the case, because the universe is too vast and the planet is too big. If you want to achieve this step, you must master the data of each planet, such as the coordinates of the universe, whether there is an atmosphere, whether it is suitable for human production, whether there are beasts rampant, and whether there are other human civilizations... In short, this is a very complicated thing, just like the rail trains from the seven major star fields more than 10,000 years ago. You are not only building a train, but you also have to build tracks, the station has a central control base, etc., and there will be a series of logistical support..."

"I understand, what you mean is that behind that technology, it's not as simple as a door."

"Yes."

"But what if the base's technology has reached the point where it can grasp the data of any star in the universe in an instant?" Yan Ruyu asked.

"This possibility is not ruled out, but I personally think it is unlikely to appear."

"Why?"

"Because the universe is not stable, it is constantly expanding, and in this expansion, countless local data are changing, such as antimatter fountains, the starry sky swallowed by white dwarfs, and a large number of asteroids and meteorites rushing around in the universe. They are changing the big data of the universe at every moment. Therefore, judging from the knowledge I have mastered, no matter how powerful a civilization is, it is impossible to master the data of the entire universe. At most, it is to simulate a large environment, and local details are simply uncontrollable."

"But why are the seven major star domain data provided by your Dark Ark in a very stable state? Also, our source star has existed for at least billions of years, but there has been no change in the source star..."

"Isn't this mudslide and the huge rocks wrapped around the change of the Source Star?" Han Xinghai interrupted Yan Ruyu's words.

"ah……"

"In fact, whether it is the universe or the planet, it changes every moment, just the difference between the big environment and the small environment. Think about it, there are countless stars burning in the universe. They are either in the peak period of life or in the decay period, and their changes will affect the environment of the surrounding planets... Even if there is no life around them, it is very likely that it will affect the visual effect of our eyes when we watch the starry sky at night."

"How to affect?" Yan Ruyu asked curiously.

"The starry sky we see at night is actually the light emitted by many stars burning, but this does not mean that these stars are still burning. Perhaps, they had already burned the fuel on it billions of years ago, and the starlight we see arrived here only billions of years later."

"Wait, is there fuel on the stars you mentioned?" For Yan Ruyu, she was very interested in everything Han Xinghai said, because after all, she lived on a planet where industry was in the enlightenment stage. In the past, she had no access to this astronomical knowledge at all.

"This... I want to mention the hundreds of thousands of years after the Big Bang, because the expansion of the universe caused the temperature to decrease, free electrons and hydrogen ions combined to form neutral hydrogen atoms, and the original fuel of the star was born. After the Big Bang, due to the fluctuations of quantum, it was amplified to the macroscopic scale. After the big bang, some places with relatively high density began to collapse slowly. Finally, they were attacked by gravity, and eventually caused high-temperature and high-pressure gases, inducing the generation of nuclear fusion and forming the first generation of stars..."

"You know so much." Yan Ruyu looked at Han Xinghai, her bright eyes full of admiration.

"No, I don't know much. All I'm talking about is some knowledge in books, and I'm just superficial memory... In fact, until now, I don't understand the principle of nuclear fusion." Han Xinghai smiled bitterly.

"It's already amazing, I don't know anything."

"You are really amazing. Under such conditions, you can figure out some of the instruments and equipment on the Dark Ark by yourself..."

“…”

...

The two of them chatted casually, but the rain stopped slowly and the mudslide did not roll over their heads.

The noisy world that was originally rumbling suddenly became quiet, and the originally dark sky revealed a clean blue sky.

Looking at the blue sky, the two of them suddenly realized that it was not night now.

Rumble...

Just as the two of them looked up at the sky, suddenly, there were loud noises coming from the ravine, deafening. The two of them looked down subconsciously and saw a cavalry with distinct armor under the ravine, galloping wildly...
