When he returned to the Chen family, it was already late, and Li Lingyun was arranged to rest in the guest room of the Chen family's villa.

When he was about to fall asleep after taking a shower, his mobile phone rang, Li Lingyun opened it and found that it was a message from Yang Ruoxi.

"Did you sleep?"

The information was very simple, but Li Lingyun was surprised, Yang Ruoxi, an iceberg beauty, has never taken the initiative to contact others, usually at this point, either she fell asleep, or she found something and worked tirelessly.

"I'm about to sleep, what's wrong? The big beauty hasn't rested yet, what are you busy with so late?" Li Lingyun replied with a message, and he didn't even notice that he was slowly changing.

After waiting for a while, I found that Yang Ruoxi had not replied to the message, it seemed that she also felt this change, and Li Lingyun would never greet each other on weekdays.

"I haven't slept yet, I'm thinking about something. Yang Ruoxi sent a message.

Li Lingyun hurriedly replied with a message: "What can't you think about tomorrow, staying up late is not a good habit, especially for beautiful women." ”

Yang Ruoxi on the other end didn't seem to be interested in this kind of unnutritious chat except for the surprise at the beginning, and simply sent a message: "Didn't you find anything unusual?"

"What's unusual? Big beauty, you have to give me some hints, I don't have any direction. Li Lingyun immediately became interested, a woman like Yang Ruoxi would not generally be untargeted.

At this time, the mobile phone rang, and it was Yang Ruoxi calling.

Li Lingyun pressed the answer button, and then heard Yang Ruoxi's somewhat sleepy voice coming over: "You haven't come back tonight, if you're still outside, let's see what's different around you." ”

Li Lingyun glanced around, then opened the window and said with a smile: "Don't play dumb riddles, big beauty, I'm in someone else's house now, this is a villa area, it's very empty, and there is no figure outside, what are you letting me see?"

Yang Ruoxi was silent for a moment, and then a cold voice came: "Then look up, if you haven't found anything unusual, you have to move out from me." ”

Yang Ruoxi is arrogant, she can see the people she can see and live with, if there is no expectation, it is absolutely impossible.

All in all, if you want to live with Yang Ruoxi, in addition to having a common hobby, you must also have matching strength, Li Lingyun is because there is a lot of ancient knowledge for Yang Ruoxi to absorb, Yang Ruoxi is not opposed to living with him.

Li Lingyun looked up at the sky as prompted.

The bright moon hangs high, sprinkling a cold glow.

It doesn't seem to be any different, but since Yang Ruoxi said so, it means that something must have happened, Li Lingyun's brain is running at a high speed, he didn't cast ancient spells, and he didn't use any spiritual power, if that's the case, even if he finds something, it means that there is still a big gap between him and Yang Ruoxi.

Feeling it a little, Li Lingyun thought about it, took out his mobile phone and looked at the time: "Something is slightly wrong, this is a little faster, why is the position of the moon still so low?"

"You've noticed it, in fact, this change has already begun, but I only found out recently. A little more time every day, it is difficult to find subtly, only by observing often, over time will you find and have doubts. "Yang Ruoxi is a meticulous person, sleeps late every day, and if there is no special thing, his life and rest will be very regular.

At one o'clock in the middle of the night, the moon is still very oblique, and at this time in the past, it is basically the middle of the moon, but at this moment the height is still like the sunset.

"I was surprised by a little extrapolation based on what had been recorded in the last few days, and what I came to was shocked. Yang Ruoxi organized the language and said: "If you don't look at the artificially set time, all this is actually no different, we all work during the day and rest at night, but if you look at the time that it is thought to be formulated, the situation is different." For example, now the working hours are eight hours a day, and the end of work is usually at five or six o'clock in the afternoon, and then the evening time is self-arranged, but in recent days, I have found that the evening time has become a little more, although it is only a little more, but for astronomy and geography, it is enough to attract attention. However, I have not collected enough data to prove my suspicions. ”

Yang Ruoxi's meaning Li Lingyun can probably understand, as a researcher of astronomy and geography, the slightest change needs to be paid enough attention, maybe it is a big discovery.

Today's situation, judging from the conclusion that Yang Ruoxi has reached, is that the time of the day has become longer, usually twenty-four hours a day, and even if you have to be precise, a day is less than twenty-four hours, so there is a saying that the month is small and the month is big, that is, the month is thirty-one days big and the month is thirty days small.

The current situation is that the day has exceeded 24 hours, and if you have to put it carefully, the time of the day is now 25 hours, and the working hours of people are still the same, still 8 hours, and the extra hour is used for rest, day after day does not seem to make a difference. But if you think that the set time is twenty-four hours, day after day, the time will become very inaccurate, and even more so when it is displayed on the mobile phone, every day is an hour slower, and after a few days, you will find that it is one o'clock in the night, but the moon is still in the treetops, which is a qualitative change that occurs after the accumulation of that hour, filling the time of the day into the night.

"What do you think is the reason for this change?" asked Yang Ruoxi on the other end of the phone.

"There are many reasons for the longer days and nights, and it is not yet known for certainty. Generally speaking, only the change of the four seasons of the year will produce the length of the day and the short night or the length of the day and the length of the night, that is, the length of the day and the short night in summer, and the short day and long night in winter, but this is the change of the four seasons, not every day, which conflicts with the current situation. Li Lingyun had thought a lot in an instant, and at the same time, the curiosity in his heart was gradually aroused, he had been trying to find the difference in this world, and now it was finally beginning to emerge.

"The reason for the change of seasons is that the earth rotates, and in the final analysis, it involves the gravitational repulsion of the sun and the earth, and I am not proficient in physics, so it is difficult to find the root of the problem. The problem at hand is that the day and night are getting longer at the same time, and the problem is relatively simple. The rotation of the earth is one day, and part of the theory of this rotation speed is also based on the sun as a reference, we will not talk about it for the time being, but from the perspective of the earth itself, it is that the earth's self-transformation is slow, and only when it slows down, will the day and night become longer at the same time, and there are many reasons for the slow self-transformation of the earth, but what we can think of at this stage should be the same. ”

Li Lingyun knew it in his heart.

The Earth's self-transformation is slow, so the day and night hours of the day will become longer.

Li Lingyun believes that there are many reasons for the slow self-transformation of the earth, but at this stage, everyone understands only one, that is, tides.
