Working from sunrise, resting from sunset...

The world is mysterious and yellow, the universe is vast and vast...

Spring and summer?21?Winter, seasons change...

Yuan Fei remembered that he was tired and fell asleep, but unexpectedly, he was in a strange place now, with many messy words appearing in front of him. These words were dancing in front of him. This should be...

Dreaming, right?

This dream is so strange. Yuan Fei could actually know that he was dreaming. This is simply...

But suddenly, I saw Mr. Cheng. This guy was wearing clothes from unknown dynasty. Baibaihu. What was he going to do?

"Ten! Ten are right! Five during the day and five at night, how great! Haha..."

Ten? What is this talking about?

But soon, the old man seemed to have transformed himself and questioned himself.

"No! Hundreds are right! It should be hundreds!"

Hundreds?

But this is not over yet. The old man seemed to have changed his outfit and said.

"No! Sixteen! Sixteen!"

But this...

"No! There are twelve! Twelve are right!"

Sixteen? Twelve?

What is this old man doing? Was he crazy?

Yuan Fei really couldn't understand, but suddenly, the old man changed his clothes again. This time it was interesting. He was wearing ancient official uniforms, and the old guy was wearing an official hat on his head!

I saw Mr. Cheng looking at something, then shouting for life, "Ha! It's time, noon!"

Noon?

Hearing this, Yuan Fei immediately ran over to take a look. After seeing this, he immediately understood!

The thing that Mr. Cheng looked at was a wooden pole, but at this time the shadow of the pole was very short and almost overlapped with the pole. When Mr. Cheng saw Yuan Fei, he pointed upwards...

sun!

Noon is of course the moment in the sun. At this time, Yuan Fei understood a little, that is what Mr. Cheng just said, and it is probably all time, which is our timing exhibition.

1o hour, 1oo engraving, or even 16 hour, and later 12, these are the timing methods that have appeared in our history, but why did Mr. Cheng tell himself about these?

Of course, Yuan Fei did not forget the thing he discussed with Mr. Cheng before. Time flies quickly on this xn7693 planet. Now what Mr. Cheng shows him... are all time! But these...

Yuan Fei still didn't understand, but Mr. Cheng was interesting.

Woo~ Woo~

"This is the Greenwich Time Train. Do you want to get on the train sir?" Mr. Cheng turned into the conductor and called Yuan Fei to let him get on. He was a complete old driver...

It was really interesting. A steam train appeared in front of Yuan Fei. This... I had a dream, so I naturally thought that I could have anything. Of course, Yuan Fei did not forget what Feng Luan had said before.

"Old man, should I kill you now?" Well, what Mr. Cheng is doing now is to communicate with Yuan Fei in a spiritual way.

But Mr. Cheng laughed, "Haha... you kill it, it doesn't matter, the old man is not a human being!"

That's right. This old man is not a human, he is an immortal, or a shameless person!

"I won't joke with you anymore. What do you want to say to me?" Yuan Fei stopped beating around the bush and went straight to the point.

"Boy, I'm opening you!" Mr. Cheng smiled again, and then a lot of things appeared in an instant.

Eastern Time…

Farlockford Time…

Tokyo time…

Finally, what was particularly interesting was that with a bang, Yuan Fei's eyes changed again.

"The lamb skewers! The lamb skewers!" Mr. Cheng wore a small hat, a young man's robe, and a crappy accent, and barbecued there!

"You, you..." Yuan Fei wanted to scold him, why are you pretending to be Afanasi!

"Aha, I'm Uncle Avatar! My mutton skewers are simply, tsk tsk tsk tsk..." This old man is quite immersed in the show.

"..." Yuan Fei's expression...

But as the old man looked at the watch, "Hey! Our sun is setting!"

This is...the time displayed on this watch is 9 o'clock!

At this time, Yuan Fei's mind seemed to explode somewhere, and he only heard him say, "Mr. Cheng, what you want to say is that the definition of time is different?"

"Ahh! You kid is really good, not bad, hahaha..." Old Cheng laughed and pointed at Yuan Fei with the mutton skewers in his hand.

In an instant, the picture in front of him seemed to disappear suddenly. At this moment, Old Cheng was standing in front of Yuan Fei, and the two of them seemed to be in the universe, with countless stars floating around them!

"Boy, have you thought of it?" Mr. Cheng still smiled that way.

"..." Yuan Fei's mind was running at this moment!

My human definition of time is different. Historically, it has been changing. In the past, humans always looked at the sun, just like a sundial. In this way, every region has its own time. Thinking about the present, the people on this planet are also humans, and the time they are in is much faster than ours, but this is different...

"Is it just a definition?" Mr. Cheng's voice came again.

Right! Is it just a definition?

Yuan Fei naturally thought of the example mentioned in "A Brief History of Time", which was to let a pair of twins live on the mountain and the other on the plain, and then the two people would have one old and one old and one slow, and the other old and one old on the mountain would have a faster time.

In addition, two identical clocks that walk very accurately are placed on the top and bottom of the water tower, and the one below walks slower.

Obviously, even on Earth, time itself is different, and we humans are still constantly defining our time.

The definitions of time shown by Mr. Cheng are all the various definitions of time in human history. We used to look at the sun, but later timers such as clocks appeared. However, even if there are clocks, they do not completely unify the time, such as the Eastern Time of the United States. In addition, from ancient times to the present, the meaning of unit time is different.

In ancient times, humans had almost no gratitude for a second because they could not do anything at all. But later, on the 21st century, that second was long, and they killed an opponent on the field and killed a person with guns. In addition, the amount of transactions in the stock market in one second was so scary!

"This planet, the time of xn7693 itself is different from that of Kiba Star!" Yuan Fei said.

"That's right, so..." Mr. Cheng continued.

"So, this planet is an experimental star!"

"Ahhh! That's right!"

Mr. Cheng clapped his hands happily, but Yuan Fei was not very excited at this time, but instead he fell into deep thought!

The deduction just now is actually very simple. It starts with the basic situation. Let’s talk about Kiba Star, which is an extreme earth planet. The definition of “similar to the earth” is naturally to have an atmosphere, water, and vegetation... But now, there should be one more condition, that is...

Time is similar to the earth!

Yes, what a simple truth, but this truth was ignored by Yuan Fei. Even Yuan Fei was sure that most people on Kiba Star ignored it.

Then, if this time is similar to the earth, you can draw a very interesting conclusion...

At this time, human science and technology level can allow humans to live on the Muchang Star 260,000 light years away from the Earth. So, with the size of the original Milky Way and the current Andromeda Galaxy, such stars carry planets, and then the planets have the conditions for survival, there must be many such planets.

However, these planets are likely to have problems with time!

Either it is fast or it is slow. Yuan Fei still remembers a classic science fiction movie that was remade many times, called "Interstellar", one of which is full of water, and the time of that planet is...

So, these planets became experimental stars, just like this xn7693. However, there is a condition for this deduction, that is... the polar terrestrial planet of Muchang is the only one!

By the way, the time of the Muchang Star is similar to the time on Earth... Yuan Fei was very clear at this time that it could not be exactly the same. It was impossible for two completely the same planets in the universe, and the time on it could not be exactly the same.

But!

If there is a problem with this premise, then what if there is more than one planet similar to Earth's time?

This idea... For some reason, Yuan Fei felt inexplicable fear!

If there are polar Earth planets other than Kiba Star, it must be not an experimental star, which is similar to Kiba Star, but... why don't we Kiba Star people know?

Could it be...

Yuan Fei felt that other extreme earth planets should exist because this is a vast universe. The Milky Way is more than two million light-years old, and the Andromeda galaxy is almost as big as this big, and how could it be that large or such a vast star field not exist?

"Boy, it's already great that you can understand so much now. Although you haven't understood the key essence, it's OK. Don't think about it anymore." Mr. Cheng's voice appeared again, interrupting Yuan Fei's thinking.

"Mr. Cheng, can't you tell me directly? Can't you explain the final answer?" Yuan Fei said helplessly.

"Boy, you have to understand it yourself, because only this is the best and most meaningful..." After Mr. Cheng said, he seemed a little distracted, and then said, "Haha, even if I want to explain, hehe..."

this……

Yuan Fei wanted to say something, but suddenly, there was a harsh sound in his ear.

Beep! Beep!

"Tip: The star rating task changes, the Black Iron Star's star rating team is about to reach 6xn7693. The original tasks of each class of Kiba Star remain unchanged, and they compete with each class of Black Iron Star, adhering to the principles of fairness, justice and openness. Both sides must... "

This is what Yuan Fei gave with his badge, and this...

Black Iron Star?
