Sure enough, it didn't take long for Mu Songbai to walk out of the Lechuan River by himself, and it took no longer than Chen Xinyan, which surprised Yu Lei and Shen Di. In fact, if it weren't for the fact that the two of them were the apprentices of Chen Jun's ancestor, this comprehension alone would make people's jaws drop when put into the outside world.

The Tao of Time is so vast and profound, how can it be so easy to comprehend?

The most obvious manifestation is that although Chen Xinyan has comprehended, he still cannot apply it practically, that is to say, what he has realized is only the accumulation of knowledge, but it cannot be turned into a weapon in the short term. And Mu Songbai has the innate ability to walk in time, and her comprehension of time is applied to this innate ability.

The Tao of Time is vast and complex, and there are many paths just to reach the stillness of time. What Chen Xinshen realized from the Lechuan River is the gravitational attraction of Lethe River, so that the gravitational field changes the speed of time flow to achieve relative rest. Mu Songbai is different, what she sees from the Lechuan River is not a still, gravitational Lethe River, but a flowing Lethe River, so she realizes that she can achieve stillness by reaching the speed of light, and even surpassing the speed of light to achieve time reversal, which is quite compatible with her talent for time and space walking.

Mu Songbai's current chronochronowalking has not yet been able to enter the higher dimensional space to traverse, and the teleportation and obstacle traversal she is currently doing are more of self-decomposition into fine particles and teleporting to distant places for recombination. Only by mastering the way of time and space, it is possible to swim in the long river of time and space, so this realization is far more meaningful to her than Chen Xinyan, at least on the two paths of time and space, she has taken both feet.

"The Lechuan River is one of the magic weapons of the Emperor of the Northern Yin Dynasty, containing the way of time, and everyone will have a different encounter when they enter it. As long as you can rely on your own understanding of time to come out of this Lethe River alive, you will have your own opinions. Just now I watched the process of your enlightenment, and from the point of view of reaching the goal of time being relatively static, Chen Xinyan walked the path of gravity, while Xiao Songbai walked the path of the speed of light. Yu Lei saw Chen Xinyan pull up Mu Songbai, so he explained to the two with a smile.

Hearing this, Chen Xinyan turned around and said with a smile: "Senior, in fact, if you just reach the point where time is relatively still, I not only have an understanding of gravity, but in fact, I also have an understanding of the cold and biting water of the Lechuan River. ”

"The river? The river was cold when I first entered, but it won't be cold after you leave." Mu Songbai was a little puzzled.

"I said that everyone has a different experience, and the Lethe River will manifest into different things according to personal understanding. Yu Lei looked at Chen Xinyan with interest.

"Two paths?" asked Shen Tu suddenly.

Chen Xinyan nodded and explained: "One and a half, in addition to gravity, because of the amazing cold river, I have found something else. All objects on the earth are composed of molecules and atoms, and molecules and atoms have to move irregularly all the time, and the macroscopic manifestation of this irregular motion is temperature. Although the ice is cold, there are still molecules that have to move all the time, but as long as the temperature reaches absolute zero, all the atoms and molecules in the object will be relatively stationary. Our time doesn't stand still, but we look at it as if it's magical. However, Jedi zero is only a concept, but it is difficult to achieve, absolute zero can be infinitely close, but it cannot be reached, so it can only be regarded as half a road. Thermodynamically speaking, entropy will only keep increasing, and the arrow of time will keep moving forward in the senses, perhaps solving absolute zero in order to be complete. ”

"I don't understand. Mu Songbai's little head shook like a rattle.

"Hmph, trail. Shen Tu didn't say disdainfully.

Yu Lei waved his hand to stop the two of them from interrupting, and encouraged: "Let's talk about it, in fact, I am quite interested in the combination of modern science and cultivation. ”

Chen Xinyan thought for a moment and continued: "Entropy is a variable that describes the degree of disorder of a system, the more disordered it is, the greater the entropy, and the expansion of the universe is an entropy increase process that tends to disorder. The entropy of a system does not decrease, and any irreversible process will lead to an increase in entropy, just as a person will grow up, and the glass on the table will not recover. All human cells and ideas are made up of hundreds of millions of neurons, and then refined are composed and generated by a certain number of quanta, and our own individual existence is constantly renewed. In a sense, the current self is not the same as it was seven years ago, just like ......"

"You can't step into the same river twice. ”

Yu Lei scratched his head in embarrassment, and said with a look of adoration: "Although I don't know what you're talking about, I feel like it's very powerful." Our monks perceive the Great Dao of Heaven and Earth, but it is a natural, mysterious, and seemingly understandable feeling, knowing it but not knowing the reason, which is far less thorough than you can see. ”

Being looked at like this by a ghost emperor who cultivated to an unknown height, Chen Xinyan was also a little unnatural, and could only laugh dryly: "This can't be said thoroughly, it's just that the existence and laws of the universe are so precise and wonderful, and even disorder is a kind of order, and if there is no law, it is not a law, so I am thinking about whether all this is a coincidence or whether there is really a heavenly way." In fact, I wonder if our spiritual power is not visible to the naked eye and cannot be observed by the existing science, so it will be a kind of dark energy. I am not completely clueless about the practical application of the comprehension of the way of time, the way of time is also a kind of truth of heaven and earth and the truth of the universe, at least this enlightenment has strengthened my talent for the arrow of absolute truth. ”

"It seems that your second senior brother sent you here, and it is indeed right, come with me, I will take you to meet the Emperor of the Northern Yin Dynasty. Yu Lei sighed, turned around and took the lead, "It's not a secret, the Great Emperor rules the Netherworld, governs all evils, and his cultivation has already taken over the heavens and the earth." As early as a thousand years ago, the emperor went to retreat and practice, just counting the days, the emperor should have been out of the customs a few years ago. But in the first few months, we still haven't waited for him to come out. In the first few years, we thought that the emperor had realized something during his retreat, so we didn't dare to disturb him. Later, we were a little relieved, so we shook the awakening bell at the door of his retreat stone room, but we still did not wake him up. So we went in to check together, but found that the room was in a mess, and the emperor was unconscious. ”

"Could it be that he went mad?" Chen Xinyan was a little puzzled, if it wasn't for the madness, who could have such a heavenly method to make an emperor unconscious.

When it comes to the Emperor of the Northern Yin Dynasty, Shen Di's originally cool face also showed a look of worry, and he took the initiative to speak: "Impossible, when you cultivate to the realm of the Great Emperor, there is no possibility of going mad." ”

"After the emperor fell unconscious after the accident, we thought about it, and since there are not many powerful people in the human world, we asked your master for help and asked him to send his disciples to help. After sanctification, the realm can enter and exit the realm of sleeplessness in the flesh, but due to some ulterior reasons, a large number of sleepless people above the holy realm took the initiative to give up their physical bodies and enter the realm of sleepless with their souls, and no longer go back and forth to the world. Therefore, your master asked the Bright Moon Sect Master, who was still in the flesh, Chen Tafa, to come and help. Yu Lei explained.

"In other words, the second senior brother will also come?" Mu Songbai blinked.

"Calculate the time, it's almost up. Yu Lei looked up at Dongfang and muttered.
