Elder Yun held up the tea cup, took a sip of tea, and looked at Lu Chen with a deep look, "This fifth realm is mysterious and mysterious. In terms of many mysteries, it may not be higher than the fourth realm, but it has a unique

The ability of character, idealism refers to the origin."

Lu Chen was a little confused, "This disciple doesn't understand, so I asked my senior for advice."

Elder Yun smiled, it felt wonderful to be consulted by such a spiritual genius.

He put down the teacup and pointed to a leaf floating by in the stream, "Let me ask you, where did this leaf come from?"

Lu Chen looked at the drifting red maple, "Of course they fell from the trees. In late autumn, it's time for the leaves to fall."

Elder Yun took a sip of tea and said, "Do you know which tree this leaf fell from?"

Lu Chen looked at the vegetation all over the mountains and plains and fell into thinking. He seemed to understand what Elder Yun meant by the fifth realm.

"We can go back to the source and deduce the root of that leaf. What does the senior mean, is that the fifth realm is the power of the root?"

Lu Chen asked for advice.

Elder Yun looked at Lu Chen in surprise and nodded, "You are really surprising. You actually already understand the concept of the fifth realm. You really have incredible qualifications."

Lu Chen knew clearly in his heart that his third talent involved the ultimate secret of sword intention. He didn't expect that he already had the supreme inheritance, but he still didn't know how to use it.

He has a natural aptitude for the Soul Intent, but he cannot be said to be proficient in it, especially the Karmic Sword Intent, which he actually only has a partial understanding of.

His cause and effect is not the cause and effect that the Immortal King in the perfect world can derive from looking down at the long river of time and observing reincarnation, but a broader sense of cause and effect, seeing the big from the small, and turning the world upside down from the smallest.

In fact, when adventuring in the perfect world, many masters recognized his sword intention and knew that it was the power of cause and effect. No one seemed particularly surprised, but if they were asked to use it, no one could do it.

Some giant immortal kings understand the law of cause and effect, but they are very superficial and cannot escape from it. This is an almost endless law. Even if they become immortal emperors, who dares to say that they have understood the law of cause and effect?

Lu Chen is naturally like this too. He can apply it in actual combat, but he still doesn't understand its underlying principles.

That's why he needs to come to Xinyi Academy to enhance his knowledge and understanding, which is very beneficial to his growth.

"Senior, I'm sorry. I'm just thinking, why is the power of the root in the first line, and why is it higher than the other four realms and becomes the fifth realm?"

Lu Chen asked for advice.

Elder Yun still pointed to the stream, and saw that the river was flowing countercurrently against the laws of nature. It was like going back in time, reversing cause and effect, and achieving a reversal. However, it was only a slight change to the whole. Therefore, it cannot be said that after he released the power of his soul, the water flow resumed.

It expires in its original position.

Cause and effect were changed and became a new established fact. The natural rules of heaven and earth were changed by this force. The leaf that just crossed the stream passed by Lu Chen and Elder Yun.

"Just now you said that leaves come from trees. You can also use ordinary deduction techniques to know which tree they come from. You can even use the soul of cause and effect to reverse cause and effect, thereby tracing back to the source and returning it to its roots.

On that tree, you will naturally know its origin."

Elder Yun spoke slowly, then changed his tone, "But if I ask you, where did that tree come from?"

Lu Chen thought for a moment, "A tree grows from a seed that takes root and absorbs the spiritual energy of heaven and earth."

"Where do seeds come from?"

Elder Yun asked again. The two of them had not practiced at all to deduce the origin of the leaf. Lu Chen had not used the Karma Blade Intention to reverse evolution, but simply discussed it.

"The seeds...naturally come from the previous tree."

Lu Chen was a little confused, not knowing what Elder Yun wanted to say.

Elder Yun smiled mysteriously, "What about the tree?"

Lu Chen felt his head start to hurt, "Of course...climb a tree?"

"What about the last tree?"

Elder Yun was not in a hurry and asked while sipping tea leisurely.

.

Lu Chen paused for a moment and then said hesitantly: "Go up a tree?"

Elder Yun smiled and said, "It's infinite if we push forward. Where is the root and where is the source?"

Lu Chen was completely confused. After thinking for a moment, he shook his head and asked, "So, is there any difference between tracing the origin of the root-level sword intention and the traditional deduction?"

Any cultivator with a certain level of cultivation knows some deduction skills. Compared to Lu Chen now, the weaker emperors in the world that can cover the sky can deduce ancient and modern times, and are familiar with some things. For the origin of a thing, they can.

By deducing the magic, we can learn where it comes from and what kind of history it has.

For example, Ye Fan once deduced the origin of the Kowloon Coffin in Mount Tai and saw some of the past history. Speaking from a small perspective, it can be said that Ye Fan saw part of the root cause at that time, but he did not reach the source.

And those giants of the Immortal Kings in the perfect world, overlooking the long river of time one by one, are bolder like the Red King, and dare to actually cross the long river of time. Naturally, they also have strong deduction capabilities, and can even directly trace the origin of a thing from the time level.

It would be nice to change the prefix.

In other words, if an ordinary monk asked the question that Elder Ruyun asked himself, he would be able to answer it, and through deduction, he could know where the leaf came from and where the predecessor of the tree came from.

What Lu Chen didn't understand was this. He felt that this was not a special ability. If he traced the source, he could find the source by reversing the cause and effect of the sword and exploring forward. The trajectory could also be traced by deduction techniques.

When Elder Yun heard Lu Chen's doubts, he put down his tea cup, added a new cup of tea for himself, and also gave Lu Chen a cup. Lu Chen thanked him and took it.

He looked at the fallen leaves in the mountains and said, "The difference is that deduction is deduction. Cause and effect reversal essentially has the same theory as deduction. It's just that one can actually affect reality, while the other can only illustratively see and know part of the truth."

, and the root-level soul is truly tracing back to the source, going backwards, wherever the heart goes, and where the mind points, there is no escape, and it goes straight to the source."

Elder Yun's expression was serious, "The so-called root does not exist in theory, but conceptually it does exist. In fact, in the process of tracing back, we can never reach the ultimate root. We can only conceptually

At the same time, this is also a dangerous process."

Lu Chen thought carefully about Elder Yun's words, "Senior said that if you use this ability to trace it back to the source, it may not be the real thing. So can this be called a root-level soul? It's not worthy of the name."

Elder Yun smiled and said, "You kid, what are you talking about? Have you ever seen the true root-level soul? If you had witnessed its miracles with your own eyes and observed its changes, you wouldn't say that. It is not unworthy of the name.

The problem..."

Elder Yun paused for a moment, then pointed to the leaf that flowed back from the stream, "... Do you know what will happen if the root-level soul traces back infinitely and you strike out with an invincible sword?

?」

Lu Chen thought for a moment and seemed to have some understanding in his mind, but he still shook his head and wanted to hear Elder Yun's opinion.

He wanted to say that not only had he seen it, but he could also use it, although he didn't quite understand the principle.

If Elder Yun knew that Lu Chen had used Root Level Sword Intent before, he would probably curse him loudly and marvel at Lu Chen's audacity.

"It will disappear, all existence will disappear, time and space will lose their meaning, everything in the universe, heaven and earth, and even all the heavens and worlds will disappear."

Elder Yun said word for word.

Lu Chen was stunned for a moment, "I just chopped off a leaf, and this is what happens?"

Elder Yun took a sip of tea and said slowly: "According to some theories of the ancient taboo beings, the origin of all things is that all matter and energy have a source, and they may come from one place. You see it now as a leaf, but there are countless

Before the era, it might be a part of the human body. Pushing forward, it might also be the core composed of a certain star... There is no end. Maybe Chapter 1,494: Lu Chen: Yes

no possibility

Yes, that is the theoretical real root or origin, but there is also a paradox."

Lu Chen answered: "Before the origin, where did it come from?"

Elder Yun nodded, "This seems to be a strange circle. It is difficult for wise men to escape. Perhaps only fools can understand it. Let's not talk about the long-term. I will only talk about the present. If you have a sword, you are theoretically invincible. Use the root of the sword to cut to the direction.

The root of this leaf will be traced upward until you stop exploring the root."

After Lu Chen listened to Elder Yun's explanation, he suddenly felt a little scared. He had used it foolishly before, relying entirely on his feeling, and not paying attention to how far the source of the sword intent could be traced.

If you don't control yourself well, won't you become the great sinner responsible for the destruction of all worlds?

"Boy, what's that expression on your face?"

Elder Yun was a little puzzled by the change in Lu Chen's eyes. Shouldn't the emotions that should be shown now be shock, yearning, admiration and other emotions?

"Senior...I would like to ask you for advice..."

Lu Chen hesitated and spoke, "If, I mean if, there is a person who doesn't understand the root soul very well, but he uses it..."

Before he finished speaking, Elder Yun sneered and shook his head: "That's impossible, your kid's assumption is not valid."

Lu Chen was a little embarrassed, "So I said it's if, senior, just treat it as a hypothesis."

"It's impossible even if it's hypothetical. How can someone who doesn't understand the deep meaning of the source use this ability?"

Elder Yun shook his head again.

Lu Chen was a little confused, "Senior, please listen to what I have to say. It is assumed that someone used it, but he didn't understand how terrifying this power was, so he used it like that, and with a powerful sword, he killed an entire world.

Will there be any hidden dangers on behalf of the will?"

Elder Yun looked at Lu Chen with a strange look, "What kind of proposition are you talking about... Even if what you said is possible, if this is the case, most of the world will disappear, along with the other world.

If the upper universe and space related to the birth of the universe are powerful enough, it may trigger a super chain reaction and cause a large-scale collapse."

Lu Chen's heart tightened and he continued to ask for advice: "Wouldn't it happen that the worlds disappeared like what the senior said?"

Elder Yun shook his head and said with a smile: "As I just said, the prerequisite for that situation is that you have an unrivaled slash, because when all things are traced back to their source, you will always encounter powerful creatures in the process.

If you can't wipe him out with one knife, you'll have to stop."

Lu Chen breathed a sigh of relief and asked again: "In other words, the power of that knife will be gradually weakened and dissipated in the process of tracing its origin?"

Elder Yun took a sip of tea and said, "You are right to understand this. Generally speaking, encountering obstacles will always consume a certain amount of strength.
