Wandao long distance

Chapter 639 Backtracking and Light Cones

When the whole world, only you can perceive the truth...

When only you realize that this void world is being constantly manipulated by someone.

Even if you know that other people have free will, it's just... This kind of free will is weak and ridiculous.

They have free will simply because the Mighty Ones want them to.

If they wanted to, the Mighty Ones could also make the whole world change according to their wishes, allowing those 'free wills' to change at will.

It is easy to modify memory, erase experience, and reshape personality.

When you understand this kind of thing, and at the same time... you also have the perspective of these powerful beings, you will be very painful.

Especially when you are not a powerful person.

You can only watch all this helplessly, and keep repeating the trajectory set by the mighty one.

You have free will simply because they require you to have free will.

If you don't care about anything, then it's okay, you can go crazy, you can vent your pain violently, mess up everything around you, and pour out all your dissatisfaction.

But Li Qi couldn't do it. Opposite him were rabbits and little bastards. If he vented, they would only think that what happened in the past 300 years, the reunion would turn into worry, and the rare joy would be clouded.

Although...it's true that many things happened, but Li Qi really didn't want to do this.

Dozens of times passed.

Li Qi was really tired, and Shen Shuibi asked him dozens of times.

I don't know when it started, the rabbit can always sense that something is wrong with Li Qi, but Li Qi can't say anything.

This is the perspective of the witch god, so don't talk nonsense.

Just as the great witch Chang Xi said, just knowing some things will bring about disaster.

However, after dozens of times, Li Qi woke up.

This time, it was not in Guanghan.

Li Qi took a deep breath.

What followed was not joy, but 'relief'.

Finally... finally.

If it was repeated, Li Qining would keep reincarnating in the battle of life and death, and he didn't want to experience time with his family over and over again.

However, if it wasn't Guanghan, this should be a war zone, right?

He was still looking around when a voice came from beside him: "Li Qi?"

Before Li Qi could speak, Li Shiwei next to him shouted in surprise: "Uncle Bo Yue?!"

Li Qi also found the source of the voice. Not far away, there were some halos of world group formations. This place should be in a certain world, and it is also the kind of world that is about to die.

And at the very center of those halos surrounding hundreds of miles, about seventy miles away from him, Boyue was sitting there.

This is really, a coincidence.

This is probably a real coincidence, because no one will control such insignificant things, and Li Qi has not observed any weird fluctuations in the line of cause and effect, and the witch god has said that from now on, no one can arrange Li Qi's Destiny, Li Qi truly possessed reality and got out of this situation.

That was fate.

"Haha, Boyue, I didn't expect to be working under your hands this time." Li Qi smiled and lifted his spirits, and his numb heart relaxed a little.

People still need some new things to stimulate, and there is always one thing of infinite reincarnation, even Li Qi can't bear it.

And on Boyue's side, while processing the information sent by the World Group Formation, he said: "It's really you, kid, why are you still dragging your family... I can't move, come here."

"What? Are you not happy that I'm here to be your palm killing team? How many people can be better than me?" Li Qi said, and at the same time, he and Shen Shuibi walked away from Lingcha.

Lingcha disappeared the moment Li Qi left.

Guanghan's Lingcha is said to be able to go anywhere, but if you want to go to Guanghan, you have to run by yourself, and you can't teleport it. This is a completely one-way communication method.

"Happy... you bastard, you are already at the fifth rank, can you slow down your cultivation speed?" Boyue sighed, his face was full of exhaustion.

Seventy miles is an instant for the fifth grade, so while speaking, Li Qi has brought Shen Shuibi to Bo Yue.

Although Shen Shuibi has become a mother now and her personality has changed a lot, she is still a restrained and dull person on the whole. She didn't speak, but just pulled Li Shiwei to stand beside her.

Li Shiwei also knew that his father was talking about business with his uncle, so he didn't interrupt, but kept looking around, especially looking at the formations of the world group.

This thing is an upgraded version of the Wudao Shanshui Great Formation, which can deploy the resources of an entire world group, and its effectiveness is terrible. It is the main force against the fortress of the humanitarian war.

"I also really want to calm down, but unfortunately, I might die if I settle down, the situation is forcing me, there is no way..." Li Qi shook his head and sighed.

He tried his best to restore himself to normal and not to be seen by others.

Boyue is only at rank six at the moment, the same as when Li Qi was the conductor.

"Okay, you know it's not very good, but the situation here is not very good, as you can see, my palm killing team has almost lost, so I reached out to the higher-ups for support , you have a lot to do."

"Small things, I just do things when I come here. It really makes me idle and wait to win, but it's not beautiful. How is the situation on your side?" Li Qi sat down and asked Boyue.

Since the two are acquaintances, they didn't have any extra reservations and went straight to the point.

"The opponent is very powerful. I used an ambush to defeat my palm-killing team, which made me unable to contain the humane army. Now I am in a passive situation and it is difficult to break the situation." Boyue said bluntly.

"It's really difficult." Li Qi nodded, he was also played by Liu Junyi in this way.

Liu Junyi first defeated Li Qi's Slaughter Squad, and then used dog-walking tactics to trick the Wudao army into applause. In the end, Li Qi was desperate, and in addition to temporarily mastering the ability of cause and effect, and the third-rank treasure to help him advance, this Only then can Liu Junyi be defeated.

To be honest, Li Qi couldn't play against Liu Junyi in a pure battlefield game.

Boyue continued: "I have tried several times with the demon seed, cutting off many futures I don't want, but it is still difficult to win. Even if I can do it all over again, the opponent has not given me a chance."

These words made Li Qi stunned for a moment.

Wait, he suddenly remembered.

Boyue's demon seed!It can cut off Zhou Guang!And he can do it when he is at the ninth rank.

Is this some kind of special 'traceback'?
It's like my true knowledge rhyme, it is the manifestation of some special power, as a young master, basically everyone has such a skill.

"Wait a minute, don't talk about this, let me ask first, does your demon seed have a range limit?" Li Qi asked suddenly.

"Ah? You have a grudge against me? Are you looking for my footsteps?" Bo Yue smiled.

That's not very polite, asking this is just looking for Bo Yue's weakness.

"No, I recently encountered some things related to you, I will trade with you..." Li Qi also realized that something was wrong with him, but he couldn't give up.

However, Bo Yue waved his hand: "It's okay, between you and me, the ninth rank trusts each other's life and death, how can I not trust you? But do you really need this information? It's even more important than battlefield information?"

At this time, Shen Shuibi was also sensible, coughed twice, and claimed that she wanted to go around to see the formations of the world, and took Li Shiwei there.

Li Qi and Boyue naturally watched her leave, and only Boyue and Li Qi were left at the scene.

Therefore, Li Qi nodded: "Well, this is very important to me, and if I know this, I might be able to help you win the battlefield on your side."

"Okay, I believe you, then you can ask." Boyue was also very straightforward, and directly admitted it.

"It's still the same question, does the demon seed have a range limit?" Li Qi asked.

"Yes, it mainly depends on the pressure of the surrounding heavens, my mana level, and the length of the retrospective time." Boyue nodded: "For me now, if I am outside the domain, if I cut off one second, the coverage area is about 60 miles, but I can adjust it. , if you cut off ten seconds, the coverage radius will be doubled."

"If it is in the world, this number will probably be fixed at around five miles, because I can't support cutting off more time and scope, five miles... the time for backtracking is probably less than an instant, and it can't even be counted as backtracking. It is considered suspended, so there is basically no usability in the world, and the way of heaven in the world is too strong."

Li Qi immediately realized something: "That is to say, this range is linked to time. The longer it is cut off, the larger the range it can affect, and the consumed mana will also increase exponentially?"

"Well, that's it." Boyue agreed, and said: "This range is generally related to the limit of the heaven. I can also manually compress the range, but that requires me to adjust the speed of the limit of the heaven."

With that said, he demonstrated it.

Boyue raised his hand, the demon seed activated, and Li Qi also immediately felt the Zhouguang around him begin to peel off, the range...is the speed of light x time.

Li Qi is a smart person, just this move, he immediately realized the reason.

is the speed of light.

The limit of Boyue's backtracking is the speed of light.

He used the magic seed to go back one second, then he had to go back one second at the speed of light, no matter how much the speed of light was, whether it was changed or not.

Or it can be put this way... What he traced back was the light cone.

All events in the universe spread over time, like spreading around. As time increases, the range of influence of events also becomes larger. When the ranges in each time period are stacked together, a cone is finally formed.

Suppose you light a candle and it spreads light around.

The moment the candle is lit, the light will rush out in all directions, flying at the speed of light, thus forming a continuously growing bubble.

You can never go beyond this bubble, because it is impossible for an object with mass to exceed the speed of light, and it is impossible to exceed the limit of heaven.

You can modify the limit of the heavens, just like all extraterrestrial travelers, but the light will also speed up accordingly, and you have never been able to exceed this limit.

This is the meaning of 'the limit of the law of heaven', which can be modified but cannot be surpassed.

Therefore you cannot escape from this bubble.

Cut each moment of this bubble into planes, and combine them to see a cone, which starts from the candle and extends to the infinite future.

This cone expands from the past to the future time is the central axis of this cone, the sides of the cone are inclined at 45 degrees, because the distance light travels in a given time is absolute, for example light travels one light year in space in a year distance, this cone is the light cone.

The 'point' at the front of the light cone is the cause of the light cone.

The circle behind is all the fruits.

The origin is the beginning of the event, the direction of increasing time is the future of this event, and the direction of decreasing time is the past of this event.

The cause of this event and all the effects on the future are all within this cone, and thus, the causal relationship in the universe is created.

This is the most important law of cause and effect in the universe.

Within the cone of light is destiny.

Any event in the universe can only affect the objects in its future light cone, and all objects outside the future light cone of the event will not be affected by the event.

It is impossible for people outside the light cone to understand what is happening inside the light cone, and people inside the light cone cannot understand the events outside the light cone.

Starting from the light cone, the universe is clearly divided.

Therefore, the backtracking of the demon seed can only backtrack one light cone.

And therefore, the backtracking will not produce any causal paradox, because the things inside the light cone can’t affect the outside, so the partial backtracking will not produce any consequences.

Then... Maybe the backtracking of the mighty ones also follow the same principle?It's just that the technique is more advanced, similar to the comparison between the fire in the primeval forest and nuclear fusion.

Although they all use temperature, the difference is unreasonable.

If so...

Li Qi shook his head.

Even so, there seemed to be nothing he could do.

However, this conjecture should be of some use to Boyue?
So, Li Qi said: "Recently... I have some experience with the line of cause and effect. I suddenly heard that your demon species is like this. I have a guess. Just listen."

After finishing speaking, Li Qi began to give a speech in front of Boyue.

The threads of cause and effect unfold and, at the same time, join together with the 'cones of light'.

Time and space, cause and effect, merged into one at this moment.

It turns out that the line of cause and effect is not two-dimensional.

Previously, Li Qi's understanding of cause and effect was 'cause lines' plus 'effect points', and then tiled out a huge network, but this network is flat and two-dimensional.

But... if combined with time and space?
At this moment, the flat network becomes a "stereo" like a light cone, and the law of causality moves to a new height at this moment, just like a two-dimensional creature has evolved to a three-dimensional one.

However, Li Qi's speech was a bit lame.

He is very familiar with cause and effect, but he doesn't understand the time and space represented by the demon species.

But it just so happened that Boyue understood very well.

Boyue immediately stood up from the world formation and sat down in front of Li Qi.

He also began to give a speech, using his own understanding to supplement Li Qi's lack of understanding of demon seeds and time and space.

The two are one, complementing each other what the other can't, and the understanding of the path of the two of them is fused together in a strange way.

It seems...it should be so ordinary by nature.

Time and space and cause and effect are originally one.

Cause and effect have a strict time relationship.

There must be a cause first and then an effect.

At the same time, the light cone itself is also a manifestation of space, and time and space are integrated, and the relationship between cause and effect in time can also be projected into space and become the trajectory of space.

Yes, time is the trajectory of things moving in space, and time is a movement axis of space.

In this way, the law of causality and the law of space-time can be unified.

To Li Qi, this was just an inspiration.

But for Boyue, it was an opportunity for a breakthrough!
