From the dragon race to penetrate the world

Chapter 1335 The ghost of cause and effect

It was like a dream, Lu Chen wondered if he had seen a ghost.

He circled around the small world and retraced the way he came in.

When he walked to the end of Linzhong Road and heard the sound of the mountain spring, he looked back subconsciously, as if hoping someone would stop him.

But when he turned his head and looked, the river beach where he used to barbecue with the old man was empty, only sand and pebbles all over the ground.

At this time, Lu Chen's mind was in chaos. He remembered what the old man had said to him a few days ago, and discussed the cause and effect.

Because Lu Chen cultivated causal sword intent, but his causal sword intent was learned from a certain version of Plath Lu Chen in the future, and evolved to this point.

He entered the Tao with martial arts and touched cause and effect. In fact, the essence of cause and effect has not yet been fully understood. In the realm of sword intent, he still has a long way to go.

But the old man, as a fairy king-level existence that can traverse the long river of time, of course has a much better understanding of cause and effect than Lu Chen, so he gave some pointers.

He said that experts who have reached a certain level will have different views on karma. Some people are very jealous and do not want to be easily contaminated with any karma, which leads them to sit in the dead all year round and almost never appear in the world.

There are also some people who think that my fate is up to me, unscrupulous, and firmly believe that there is no cause and effect to liquidate themselves, as long as they are strong enough, they will not be afraid of letting others add to their bodies.

The old man in common clothes said that in fact, these ideas have their own reasons, and sometimes it is necessary to think about the essence of cause and effect numbered notation.

Together, cause and effect are always related things, but all related things are generally balanced, and if one side changes, the other side will also cause changes.

Therefore, there is no beginning, no cause and effect, if there is an effect, there will be a cause, and if there is a cause, there will be an effect.

In other words, the effect in the future will also affect the cause in the present, the effect can be first, and then the cause.

The essence of the Dao of Karma lies in this, and the infinite transformations that have appeared since then are the extension of this Dao.

Some people say that the end of science is theology, but Lu Chen also remembered what Chu Zihang said to himself. After theology is thoroughly understood, it becomes science.

In fact, there is no scientific theology in the world, and the essence is the basic truth. As long as you have insight, it is not something to be awe-inspiring and headache.

Back then, when Lu Chen and Chu Zihang entered the hometown of Shenshenli, they discussed the issue of cause and effect. In order to let himself understand some things, Chu Zihang also cited some experiments that mortals had done.

Although simple, it also reflects some truths.

Chu Zihang told him that a scientist in their hometown once conducted a double-slit interference experiment in order to prove that light is a kind of wave, because interference is a unique property of waves.

Chu Zihang told Lu Chen that this was a well-known experiment, but Lu Chen still asked Chu Zihang to explain in detail, I am illiterate, who am I afraid of?

Chu Zihang briefly explained the science to Lu Chen. In fact, he put a baffle with a small hole in front of the ordinary monochromatic light source as a monochromatic point light source, and placed another baffle with two holes in the lighting range of the small hole. A baffle with a small hole, then after the light passes through, it will be used as two secondary wave sources to emit secondary waves forward, that is, spherical waves, forming an overlapping wave field.

At this time, a receiving screen is placed far away, and a group of almost parallel straight line stripes can be observed on the screen.

This experiment shows that light has the nature of waves. It was once believed that light is a wave. It was not until later generations that other physicists completed it, and found that light is a wave-particle duality, because they confirmed the nature of light particles. exist.

It’s nothing to come here. Physicists who are keen to seek knowledge and truth, including many bigwigs from Kassel College, have carried out a series of experiments in order to further understand the truth of the world.

As a result, an astonishing thing was finally discovered, that is, when only one light particle is released at a time, interference still occurs, and multiple bright and alternate stripes appear.

Lu Chen didn't understand when he heard this, because although he is illiterate, he is not stupid. If he learns knowledge patiently, of course he can understand it.

At that time, Lu Chen was only at the level of a great saint, and he was more focused on martial arts. He didn't delve into the essence of the universe, so he didn't study the light of each world carefully. He only knew that the physical rules of different universes were different, but The conversion principle is generally in line with some common sense of modern physics.

According to what Chu Zihang said before, light is a wave-particle duality. Only a large number of photons are emitted at the same time. Because of the fast speed of light and the short distance, they will interfere with each other, but there is only one light particle. How did it interfere?
Could it be that it cannot interfere with itself? As a light particle, can it pass through two slits at the same time?

Then Chu Zihang popularized the superposition state with himself, and took out Schrödinger’s cat he had heard as an example again. The cat is in the superposition state of dead or alive, and only measurement, that is, observation, can make this superposition state collapse.

Here, photons are in a superposition state that passes through both slit 1 and slit 2. As long as you do not measure at the slit, you cannot be sure which slit the photon that reaches the screen comes from. .

Hearing this at the time, Lu Chen immediately captured a photon research. For his cultivation at that time, if it was placed in the dragon universe, it was just a trivial matter, but it was not so easy in the home world.

Because in the super-large world universe, he and Chu Zihang discovered long ago that the propagation speed of light is much faster than their previous common sense. This also explains why there are people fighting in the depths of the universe, and many people can See why.

Lu Chen wanted to disassemble the photon, but unexpectedly found that he couldn't do it, which surprised him at the time.

It's not that he is conceited, but since he stepped on the technology after becoming stronger, he feels that the extraordinary side is the strongest. I can manipulate some elements of nature, isn't it easy to grasp?
Moreover, some secret techniques among monks can indeed turn stones into gold and change the nature of elements. Lu Chen can also do this, but when it reaches the smallest point, he finds that he can't see through it.

He also couldn't understand what people couldn't see through, which made Lu Chen puzzled.

He also had to be patient and listen to Chu Zihang's lecture, and listen to how those great figures in the physics world did their research.

When Chu Zihang mentioned this matter, he also had a strange expression on his face, saying that physicists use light sources to emit only one photon at a time and open both slits, but by placing photodetectors at the slits, it means that every photon can be observed Which slit to go through.

When Lu Chen heard this, he felt a little funny, thinking that physicists really know how to do tricks, why, can it be different?

And limited by technology, in fact, the photodetectors at that time could not capture it clearly.

But the answer Chu Zihang told him next made Lu Chen feel a little weird, because the result was that the interference pattern disappeared, and it just became two simple beams of light!

That is to say, when there is an observer, the photon will not interfere with itself, just like the rules set by the gods, prohibiting mortals from spying on the truth of the world.

"It's quite skinny, just staring at it and not showing your true skills?"

Lu Chen commented this way at the time, he was a big-hearted person, and he didn't feel anything creepy. He firmly believed that with the improvement of his realm, one day he could understand cause and effect, let alone simple natural phenomena?

However, the follow-up experiment that Chu Zihang said next made Lu Chen understand why Chu Zihang told him this story.

Physicists are not reconciled, and must find out the truth of the matter, and have come up with various tricks to fight wits with photons. For example, sometimes the photoelectric detector is turned on and sometimes turned off, that is, "sneak attack"

But the photon is not fooled at all, as long as it is observed, it will not interfere with itself.

How could a group of lunatics in the equipment department of Kassel College be willing, and those old scholars still insisted on figuring out what was going on.

They speculated whether the operation of some circuits in the photoelectric detector affected the self-interference of photons, so they found a member of the secret party of super A grade to assist in the experiment. His speech spirit is a snake, which is a strong information collection The ability to speak.

Due to his high pedigree, his ability is almost psychic. In the state of deep use of speech, he can almost see the trajectory of light, so he was asked to assist in the experiment.

This time, the machine observation was changed to human observation, and the experiment started again, but the result made the group of physicists at the Kassel Institute almost go crazy.

Because when Photon was stared at by the secret party master, he still didn't interfere, and passed by honestly.

Although they know that there are dragons in the world, those people all believe in science. It is said that some people committed suicide by swallowing a gun because their beliefs collapsed.

The experiments did not stop there, and some great scientists started new activities.

The quantum erasure experiment, the blinking experiment, and the delayed selection quantum erasure experiment failed for a long time. It can be described as a battle of wits and courage for more than ten years.

Due to technical limitations, single-photon light sources can be realized with localized defects at the atomic scale. As for the definition of a single photon, it is not so much that only one photon is emitted at the same time, but it is within the limit of the photodetector that only one photon is emitted. .

That is, the card time difference, to complete the so-called individual photon.

In the end, the physicists performed another ultimate task. After the photon passed through the double slit, it was divided into two and converted into two entangled down-frequency photons A and B.

Let A move towards the screen, and B run towards the detector. Since they are entangled before, as long as the state of B is observed, the state of A can be deduced.

But this kind of experiment didn’t work, so they continued to split, and split B into B1 and B2 again, and let them enter a maze. The maze was made of special superconducting materials, and the internal structure was complicated. Even the speed of light was very fast. It takes a long time to come to an end.

They placed detection instruments on some maze paths, B1 and B2 ran randomly in the maze, and the probability of passing different detectors was also different.

The old physicists think that you can't escape now, right?I have calculated you through two floors.

But as a result, photon A still does not interfere.

Lu Chen didn't understand the meaning of this experiment at first, but after Chu Zihang explained it, he finally understood.

Since the maze is very large, photon A is very close to the baffle, so it will definitely arrive on the board first, that is to say, it has already arrived at the station before B1 or B2 is captured and deduced by the detector.

There is a time difference in between!
Because people did not observe the A photon, but only observed the "future" B photon offspring, but this still does not interfere.

Kassel College has strong funds and expanded this experiment. The maze is made of advanced materials, and it is said that it takes 5 minutes for light to pass through.

But A still does not interfere, which is a bit mysterious, just like the descendants of B photon in the future, saying that I have arrived, and telling A photon that someone is observing, please don't mess around.

And if the photons of B's ​​descendants pass through the maze without being captured by the detector, then A will interfere, just like the descendants of B's ​​photons arrive and say, I'm here, no one has discovered the secret, you can mess around.

This subverts the most basic principle of cause and effect, and becomes that there is an effect first, and then a cause.

After listening to it, Lu Chen pondered for a long time, looked at the little photon he had caught, and immediately conducted an experiment with Chu Zihang, the result was the same, as long as they watched, there would be no interference.

And find a mortal child to come and watch, and the child will discover the phenomenon of interference.

Afterwards, Lu Chen was beheaded by Plath Luchen, and he realized the Dao through the Karma Saber Intent, and finally mastered the Karma Saber Intent. When he went to the world of Shrouding Sky, because of his higher cultivation level, he also studied the basic form of the universe.

By the time of the Red Dust Immortal, he was already able to penetrate the world, and even destroying that side of the big universe was not a problem, but observing some basic phenomena, he could only capture half of the mystery.

He feels that the cause and effect is not completely linked to time, so even those strong people who have become immortal kings and can cross the long river of time may not have an insight into the principle of cause and effect, and this road is just on the way.

And now he feels that the old man in civilian clothes he saw is like a ghost in the causality of time, he only exists when he meets certain conditions and observes, otherwise the trace of his existence will disappear.

So is the other party real, or is it already dead, and what I see is just a shadow entangled in some kind of cause and effect?
At the moment when I "looked away", the old man in civilian clothes instantly collapsed into nothingness?

Because Lu Chen reflected carefully, since he happened to meet the old man in civilian clothes until today, he or Xiao Jinlong never left the old man in commoner clothes at the same time. They have always acted as observers.

There are always some super experts who cannot be seen directly, but this is the first time Lu Chen has encountered such a situation. Instead, he is there when I see him, and he is not there when I don't.

Lu Chen had an intuition that the old man still lives here. If we compare it to the photon in the experiment, it is just that the old man has a higher will. At this time, the other party does not want him to observe. There is one condition missing. Just never find it.

Lu Chen used his mana to capture the faint light from the void. With his strength, even in a perfect world, he could do this kind of thing.

He looked at the photon that was continuously circling in his hand, and thoughtfully, he took the little golden dragon and left this paradise.

When he reached the entrance of the valley, Lu Chen turned around and bowed, "The junior will come to visit the senior."

Until he left, Lu Chen didn't know whether what he saw was a ghost or a living peerless powerhouse. He only knew that he was still on his way.

Passing through the boundary membrane, Lu Chen was surprised to find that the outside scene had changed, and it would not be an exaggeration to say that the sea has changed.

Looking at the unfamiliar environment around him, he jumped up and went straight to where Zhangjiacun was originally.

And there was nothing there, only the traces of wind and rain, and the dust covered everything.

Lu Chen raised his hand and used his spiritual power to turn over the ground, only to find the ruins of Zhangjia Village in the past, and some stone tools were buried underground.

He just felt extremely weird in his heart, and immediately cast a derivation technique, trying to restore what had happened in this area.

A scene of colored glaze flashed before Lu Chen's eyes. For a thousand years, the clouds in the sky were receding. The vegetation died and died, and everything seemed to be reversed.

After half an hour, Lu Chen suddenly stopped deduction, he only deduced the scene of a small land in the mountains, he couldn't attract God's punishment, he was just a little melancholy.

I only stayed in that paradise for only one year, but the outside world has already passed 10 years!

Following some clues, he found a large tribe in the central area of ​​the Underworld Mountain Range.

Before asking about some people who work outside the tribe, those people were surprised to see Lu Chen, and they knelt down and kowtowed.

Lu Chen scanned this large tribe with hundreds of millions of people with his spiritual sense, and unexpectedly found a statue made of black iron in the center of the tribe. The statue was carved as if...it was himself.

He was a little speechless, and he didn't know what was going on until the tribal leader received the news and came out to greet him.

This is the tribe after the fusion of Zhangjia Village and the Zhenshan tribe back then. It is now called the Ghost King Tribe, because there were some legends circulating in Zhangjia Village that Lu Chen was the incarnation of the Ghost King in the Underworld Mountain Range.

In the early years, Zhangjia Village received help from Lu Chen, and they worshiped and admired it very much. In addition, Zhang Ling'er became successful in cultivation and unified the major tribes in the Underworld Mountain Range.

Lu Chen only felt weird in his heart, and thought that I did not look like a ghost king, but the supernatural powers he showed awed many tribesmen, and they firmly believed that the ghost king had manifested himself and came to visit his people in real body.

Lu Chen had no choice but to tell me his title. You can worship me, but don't call me anything.

The Ghost King Tribe was renamed the Wushen Tribe, which excited many young guys, because it sounds like a good person.
