From being threatened by Gu Immortals on the Forgotten Peak in the Qingxuan World with the wind, and then informing Zhang Lu, to the time he pretended to ascend and left Qingxuan, it was about a month or so, and then he practiced in the Qingqiu World for three full years. So how much time has passed in the corresponding super-three-dimensional world?

Recently, Zhang Lu was commissioned by Sanwu to record in detail the speed of the passage of time in each three-dimensional world—of course, the forty-three places (including the earth) that were inhabited by humans and had immortal cultivation inheritances discovered and monitored by the "Xuanqi Realm"—for comparison. Of course, the so-called "laws of heaven and earth" in each world are fundamentally the same, but the forms of expression are very strange, and the various weights and measures, including the way in which the length of time is recorded, are certainly completely different.

Theoretically speaking, the vast majority of the lower realms have a basic unit of time for the year and the day, but not necessarily the month and the hour, and the difference between the shortest and longest years and days is more than ten times!

Fortunately, the immortals have mastered such a fixed measure independent of all walks of life, that is, feeling.

People naturally have a sense of the speed of time passing, but it is very inaccurate, and it will produce great errors depending on different situations. It's like the example Albert Einstein half-jokingly gave when you sat across from a beautiful woman for an hour and it felt like only a minute had passed, and a minute in front of the fire felt like an hour had passed. This is how idioms such as the so-called "living like a year" came out.

However, the ability of immortals to control themselves is far from being comparable to that of mortals in flesh and blood, and the accuracy of perception of everything outside the body and even the entire universe is even more extraordinary. Perhaps when super-three-dimensional beings set foot in the real four-dimensional or higher-dimensional world, it will be difficult for them to accurately sense the speed of time passing, but only in the two dimensions of super-three-dimensional and three-dimensional, there is no external force that can interfere with their ability to sense.

Therefore, taking one-ten-thousandth of the super-three-dimensional collapse year as the basic unit, Zhang Lu recorded the specific length of each three-dimensional world year and day, and handed it over to Sanwu for research. However, Zhang Lu himself does not have any hope for what results Sanwu can study, although Sanwu has read a large number of earth science books, after all, it is still a wild way of civil science, and if he really wants to explore the entire three-dimensional system, it is estimated that he will have to wait for a real earth scientist to soar.

However, some simple conclusions can also be obtained, for example, those who have cultivated to the gods in the Qing Xuan World can live for three hundred years, but this is only the local time record, and if it is converted to earth time, it will be more than five hundred years. The Tianyuan world has entered a no-man's land, and the lifespan can be 170 years old, which is close to 500 years if converted to earth time. From this, it can be seen that no matter what the speed of the planet's revolution and rotation is, the average lifespan of ordinary humans and the average lifespan of top cultivators are actually not very different.

In addition, the flow rate of time between the super-three-dimensional world and the three-dimensional worlds, as well as between different three-dimensional worlds, is uneven and cannot be directly compared. In fact, Albert Einstein has long proved that the flow of time is uneven, so the flow of time in two different worlds is like two irregular curves, you can't divide them evenly, and then correspond to the cutting points one by one. For example, one year in Tengaki may be exactly the same length as two years in Qingxuan, but the next year may only be equal to one and a half years in Qingxuan......

Of course, this refers to the conclusion that a person can travel back and forth between Tianyuan and Qingxuan, but it is impossible for the humans on Tianyuan and Qingxuan to feel that the speed of time in their world has changed, and similarly, Zhang Lu measured it by one ten-thousandth of a super-three-dimensional collapse year, and although there is a small error in the results, there is no change in general.

This is because a single planet is too small a time system, and its time flow rate is relatively close to equilibrium. However, when the time of the two worlds is compared with the overall time system of the two different three-dimensional universes, the flow speed is like a turbulent wave, sometimes peaking and sometimes troughing, which is not only extremely uneven, but also almost irregular......

There is a conjecture that time is created with movement, and when something is absolutely still, time will also come to a complete standstill - like the previous generations of the Pocket Earth World that has been ripe.

However, when you look at the waves up close, they are undulating and undulating, but from a distance, they are still as smooth as a mirror. Perhaps a more appropriate analogy: an object may have a bumpy surface under a magnifying glass, but it may appear extremely smooth to the naked eye. The same is true of time, the flow of time in the universe seems to be by no means uniform, but the larger the scale it is measured by the higher dimensional beings, the closer it is to uniformity.

This larger scale is the basic time scale of the super-three-dimensional - the collapse year. Unlike mortals, the time sensed by immortals is not a small-scale or small-time system of one or two planets, but a large-scale and large-scale time system of the entire super-three-dimensional universe.

This is also the main reason why the "Xuanqi Realm" cannot make a complete work schedule for the monitoring of each Nether. The cultivators they chose to travel through and give guidance often accepted the task for a period of one year or six months, but it was impossible to set an alarm clock in the super-three-dimensional world, but only to set up a sensor device in the three-dimensional world, and when the time was approaching, they would notify Suo Tai that they knew. Therefore, it often happens that the time points of the two worlds are very close, resulting in the situation that the immortals must change shifts and substitute shifts.

Immortals don't make up for their names, but want to disguise the legendary gods of the world, to a certain extent, to make up for this shortcoming-even if they all claim to be Taisu, in fact, they have changed to different immortals, hidden behind masks, anyway, mortal cultivators can't tell the difference.

So Zhang Lu recently took the initiative to expose himself, and Suo Tai and the others were very disapproves, but based on their trust in Zhang Lu, they also allowed him to cross the line to do some experiments, so they still pinched their noses and endured it. They also have to go to Zhang Lu's class at some times, but they will never follow the example of the East and destroy their identity—Zhang Lu has what he deserves, so that only he can exert enough influence on those cultivators......

However, in general, time is moving forward, and even immortals cannot travel back in time - just like crossing the International Date Line from west to east, although you have to turn back a page of calendar, it is impossible to really go back to yesterday...... "Mysterious World" uses different time systems to travel activities, and it is only the time that stands still on the surface, and it is impossible to turn back time.

There is only one exception, that is, the Pocket Earth World, because it is in the gap between the two dimensions, and the seal of the Gu Immortals is equivalent to basically cutting off the implicit connection between the Earth and the super three-dimensional world and other three-dimensional worlds, so Zhang Lu and the others can return to the real Earth through the Pocket Earth World, and it is possible to break through the time barrier and return to the "past" even repeatedly. This is a strange phenomenon that even immortals can't understand, and it is estimated that the Gu Immortals who set up the seal and the Gu "Sin" of the pouch world also made all this by mistake, which is worthy of careful study by future earth science immortals......

Having said that, in the last three years or so of Suifeng 3D's life, Zhang Lu returned to the super 3D world, in fact, only a short period of time has passed. He didn't try to search for that Gu Immortal - the super three-dimensional world was so vast and immense, and it took almost no time for an immortal to move between different positions in the same quadrant, how could he really find a needle in a haystack, or a needle wandering around?

He just hurriedly contacted Wei Qiang and San Wu to inform them that a new crisis had arisen. The three of them gathered together, and after listening to Zhang Lu's detailed explanation, Sanwu couldn't help frowning: "I'm ...... There are still relics in the Emperor Dare Party, and it is obvious that they have also sent a wisp of thought on the seal, so they can sense that one end of the seal of the Qingxuan World has changed...... What should we do? Can we continue our project?"

The corners of Wei Qiang's mouth twitched: "You two, you used to be rough and aggressive, but now you encounter a little difficulty but are helpless - left-leaning adventurism has become right-leaning capitulationism, you have inherited Wang Ming's mantle!"

Zhang Lu glared at him: "I just reported the situation, I didn't say that I wanted to shrink, why did I surrender?

"In a sense, I am in the open, and the enemy is in the dark," Wei Qiang said with a grin, "Then we need to force him out quickly, and only by attacking him head-on while the other party is not fully prepared, we will have a chance of winning." If the legendary Imperial Party appears in full force, it is estimated that we will not be able to cope with it, but fortunately, a ...... has just appeared."

San Wu still frowned: "You mean...... They may not all have their minds on the seal, maybe only the one who is awakened?"

"I can't guarantee it, but it's very likely, otherwise, it is estimated that a group of Gu Immortals will surround Sui Feng, or follow the wind and be threatened by the queue of several Gu Immortals in a row. ”

"If you think about it like this, he's really miserable......"

"If you and I are that Gu Immortal, what will we do next?" Wei Qiang continued, "It must be the same as Zhang Lu who came to discuss with us, looking for his former companions everywhere." As far as the immortals we have come into contact with so far, there is no trace of the Imperial Party, so it can be seen that they must have scattered everywhere and gone into seclusion, and it will definitely take a certain amount of time to find Quan. Then let's make a time difference and force him to come out to face off head-on before he finds his comrades. ”

Zhang Lu asked, "Then how do you force him out?"

Wei Qiang smiled slightly: "Isn't this easy, let's just lift the seal!"

"You mean, do something to those two uninhabited sealed planets?"

"Not bad," Wei Qiang looked at Zhang Lu, "How is it, how many companions can you entangle now?"

Zhang Lu pinched his fingers and counted: "Not enough...... But if you wait a little longer, I can gather three or five more people...... But even so, if the Imperials are more connected to each other than you and I think, and they do come in groups, or most of them, we are still in danger...... What's the best solution?"
