On the other side, Zuo Yu's figure appeared in the direction where Yi Yuntian had just killed.

Gee.

Zuo Yu looked at the location he was just now, where it was as if it had been drilled by a giant drilling machine, and an abyss appeared that could not be seen at a glance.

Black holes.

And the countless rifts next to it are recovering at a speed that is within the reach of the naked eye.

"Obediently, your move is ruthless enough, if you hit it, you won't be flattened! No, if you are flattened, it will be light, and there should be no scum left. ”

Zuo Yu couldn't help shaking his head: "It's okay if it's not good, this trick is good for special relativity." ”

Recalling the moment of lightning just now, the special theory of relativity was turned on, and the shocking blow of Yi Yuntian's fast streamer approached the tip of his nose, but it seemed that time and space had come to a standstill, and he easily dodged it with a random thought.

But......

"Huh, where are you?"

"I'm here!"

There was a dull sound from under the abyss, and suddenly a fierce body rose into the sky and appeared in front of him.

The bursting aura came to the face.

However, on Yi Yuntian's handsome face, he was disgraced.

Zuo Yu smiled: "Damn, brother, how deep you go into it this time, don't poke a hole in our Earth Sect Divine Realm." ”

Belch......

Yi Yuntian has a black line, and the rolling evil qi seems to be a little weaker.

A little helpless, but also a little surprised.

"Just now...... How did you hide from it? I'm ...... already there."

"Haha, you don't understand this, do you? I just used a great figure named Albert Einstein in later generations to understand the theory of relativity created by the universe and space! This first form of relativity is called special relativity. When I was in high school, I read a book that said that within the scope of special relativity, time also becomes a real thing, which can be stretched and contracted. ”

Yi Yuntian was confused.

He is an ancient man in China thousands of years ago, and he has not returned to the earth since he was condemned to death by heaven and soared through thousands of years of resentment. For the past hundred years, he has been practicing penance in the Divine Realm of the Earth Sect, so naturally he doesn't know anything about Einstein.

And the true meaning of time, which has been realized by later generations, is even more unknown.

In fact, time does not exist in the first place.

Time is the movement of all things in the world.

The sun rises and the moon sets for one day, and the earth revolves once for a year. A hundred years is a century...... Wait a minute.

These are all definitions made by mortals in order to measure the changes in heaven and earth.

However, time itself is nothing, it does not exist like a single plant or tree.

It is entirely possible for mortals to change the definition of time, even if the sun rises and the moon sets in a year, and the earth orbits in one day, it makes no difference. It's just a different title.

The actual meaning is still the same.

The true nature of a day refers to the exchange of yin and yang between heaven and earth, while the year refers to the cycle of change of the four seasons.

These things are real, the difference between day and night is visible to the naked eye, and the changes in the seasons of spring, summer, autumn and winter are palpable, which is also the constant change of everything.

It's movement.

Time is the measure of the speed of this movement.

In other words, if the sun rises and the moon sets, the day is still a day, but in fact the time of the day is compressed. If you slow it down, the day will lengthen.

But the rising sun and the setting of the moon are the cycles of heaven and earth, and they do not change easily.

Even if it changes, mortals can't perceive it.

Only a hundred years ago, Albert Einstein spied into the mysteries of the universe through an unprecedented "thought experiment" and discovered a way to change the speed of change.

Although this method has been known by the earthlings, it is still in the verification stage, let alone mastered, due to the limitations of earth technology.

However, this is the Supreme God Realm, and the theory of relativity actually entered the Divine Realm Library with a touch of aura that comprehends heaven and earth. Zuo Yu consumed a full ten percent of the aura of the water of faith, and only then did he incorporate the content of the theory of relativity into the exercises.

What we have just used is the special theory of relativity, which redefines time in the theory of relativity.

At this time, Yi Yuntian frowned and pondered for a while, and suddenly his eyes lit up: "Compress time...... Could it be that this is the legendary day in the sky and a year on earth? Your special theory of relativity allows you to be in heaven and space, but you are spending time on earth?

"Huh?"

Zuo Yu was stunned for a moment and gave a thumbs up: "I'll go, brother, you can be so understanding." I'm thinking about how to explain it to you, I didn't study hard when I was in school, I will use this exercise, how to explain it can make you understand it, it's not easy. When you say that, you make me clear. In fact, there is a movie in later generations that probably explained it, called Interstellar. The protagonist and his gang go to a planet with a strong gravitational pull, and then the gravitational pull of that planet can stretch for a long time. Two hours on that planet is equivalent to about ten years outside. This is the embodiment of special relativity in nature!"

Belch......

Speaking of this, Yi Yuntian was confused again.

Zuo Yu waved his hand casually: "Okay, okay, don't study this complicated theory, you just need to know what is going on." As for the movie, I'll see if I can get it for you. ”

"Good!"

Yi Yuntian was also unambiguous, and nodded directly.

Anyway, that is to say, Zuo Yu's exercise can change time.

But after thinking about it like this, Yi Yuntian suddenly seemed to understand something: "Zuo Yu, I finally understand, why you can defeat me with one move." Since you have mastered such a magical technique, can't you travel through time at will? No matter how swift the enemy's attack is, you can easily dodge it, and in the same way, you can attack the enemy in this way, and the opponent can't even resist?"

"Well, that's okay, but it's not that simple. Zuo Yu shrugged his shoulders, "Look at the distance between us, it's only twenty or thirty meters in total, right? I was going to try the trick just now, so I used all my strength." Twenty or thirty meters is almost my current limit, and this move has almost exhausted the aura in my body. So I didn't hold up any defense just now, and it was just to save aura. ”

"What's more, I even have to save defense, do you think I really want to turn this move into an attack, is it even more impossible to maximize the attack range of this move? If you encounter a strong enemy, if you want to inflict fatal damage, I'm afraid that the limit distance is only a few meters left. This is more than the qi barrier of a strong master. ”

"I see. ”

Yi Yuntian nodded, and shook his head helplessly: "But this is enough, when it comes to life and death, let alone a few meters, even a few millimeters can determine the outcome of the victory." Hey, it looks like I'm even farther away from you. Forget it, then there is no need to fight again, I will completely lose today!"

After saying a few "snorts", the evil qi on his body dissolved.

There was no more disbelief on Yi Yuntian's face.

"Hehe, don't be so frustrated. There are two tricks in this theory of relativity, and I still have one trick that you don't know!"

"This ......"

Hearing this, Yi Yuntian's face completely collapsed: "One more trick?"

"That's right, but this second trick is the opposite of the first, and it's called general relativity. It's just that in the narrow sense, it is aimed at oneself, and in the broad sense, it is aimed at the outside world. ”

Zuo Yu said and took a slow breath, he didn't lie.

The special theory of relativity just now really exhausted his body's veins and spiritual energy, and at this moment, his spiritual sense flashed, and he absorbed all the remaining three or four percent of the water of faith in the Faith Divine Tripod on the spiritual platform.

It can be regarded as recovering nearly half of the energy.

And the water of faith slowly seeped out again, and it seemed to be a little faster than before, but after all, it was not that fast, and it would take a few hours to accumulate ten percent of the first weight of the God of Faith at this speed.

"But I'm running out of strength right now, so I'll show you a chance later. ”

"Hmm!"

Yi Yuntian nodded, and came to Zuo Yu, with a look of envy: "I didn't expect you to master such a magical technique, even if it is so difficult to use, but it will definitely achieve unexpected results in an emergency." ”

"Haha, if you want to learn, I can teach you too. ”

Belch......

Yi Yuntian shook his head regretfully: "Impossible." Zuo Yu, you have just come to the Supreme God Realm not long ago, I am afraid that you still don't know the things in the treasure of the God Realm, and if you want to cultivate, you rely on innate comprehension. What you comprehend can only be cultivated by yourself, and even if you tell me the content word by word, I will not be able to practice. The same is true of what I have learned. ”

"Whoosh!"

At this moment, a Japanese voice came from the stage, and Zuo Yu looked at it and was happy: "Damn, there are still island people here!"

"Ha Yi!"

The Japanese ninja warrior immediately said a word, and then spoke in a lame accent: "Zuo Yusang, Yiyun Tiansang, we are the original sword saint Tsukasa Yuan of the island country!
