The primordial era began with the Upper Cave Man.

The tributary of the past that was still flowing had no intention of entering it, but after noticing Luo Zu's observation, it tried to absorb Luo Zu's thoughts directly. After Luo Zu resisted several times, he finally managed to separate a wisp of his thoughts so that he would not be entangled by it.

As for why He took away Luo Zu's thoughts, Luo Zu could guess roughly that He probably wanted to understand the "outside world".

Spacetime is indeed wondrous; though abstract, it is composed of countless substances.

Some beings, when studying spacetime, believe that spacetime only exists when they become conscious and begin to observe it; when they fall into a state of utter stillness, devoid of any thoughts, and cease to employ any means of observation, then spacetime ceases to exist.

However, the two ancestral witches, Zhu Jiuyin and Dijiang, who are the embodiment of time and space, have never made any statement on this matter.

Otherwise, this would certainly be a classic "paper" that is well worth learning from and studying the long river of time.

Luo Zu actually agrees that time is an observable phenomenon formed by the movement of matter.

However, this makes spacetime seem contrary to our own nature, since even without observation, things like "history" will still be formed.

Therefore, Luo Zu felt that the so-called external force of observation should be further eliminated. There is no need for observation. As long as matter is still in motion, time exists.

As for whether "time" is still called "time," that's just a name, it doesn't matter much.

When a person is weak, the name is important, but when a person is strong, the name is irrelevant. That is how time is, so no matter what it is called, it will not change its essence.

Of course, the current time should be called – Zhu Jiuyin.

And another stream of time, still flowing from the past, is called—

"The Candle Dragon!"

But isn't Zhulong just Zhujiuyin? In many ancient legends, Zhulong is another name for Zhujiuyin, or Zhujiuyin is another name for Zhulong.

"Myths and legends are always ambiguous in oral tradition. Fellow Daoist Luo Zu, you are attached to appearances."

The one who followed Luo Zu's words was an ethereal figure that emerged from the long river of time.

"Zhulong? Or Zhujiuyin?" Luo Zu tried to see through the fog and get to the essence.

Unfortunately, due to the separation of time and space, and the heavy fog, even though He has now embarked on the path of tracing back through time, He still cannot see through the thick fog.

"Starting from Zhangwei Mountain and ending south of Zhongshan Mountain, it holds a candle in the darkness and light; heaven and earth have gods, and that is the only one."

Therefore, He is Zhulong.

"Fellow Daoist Luo Zu, Zhulong has long since passed away. He was originally one of the eighty-one transformations of Pangu. Later, he followed the mandate of heaven and transformed into Zhujiuyin. Therefore, Zhulong and Zhujiuyin are one family. You don't need to think too much about it." The figure then sent another string of words.

This is even more interesting. So if He is neither Zhulong nor Zhujiuyin, then who is He?

"I wonder which Hunyuan you are, my friend?" Luo Zu's words carried a strong sense of probing.

"You know me." But He still wanted to speak in riddles.

"Rahu?" Luo Zu's heart skipped a beat as a name came to mind.

"That's right," the other side replied.

"That scoundrel Hongjun is truly ruthless. If I hadn't seized Zhulong's body in my early years, he would have vanished without a trace by now," Rahu said quietly from behind the layers of mist.

Although His words filled Luo Zu with a lot of speculation, it still made it hard for him to believe that He was the legendary Rahu.

Although he found this tributary of the past under the guidance of the Killing Road, who knows if some powerful figure might be manipulating things in the dark?

The cautious Luo Zu would not trust a "stranger" so easily.

"So, the conflict between the Dao and the Demonic Path from back then was real?" Luo Zu wanted to probe further.

"What is this talk of Tao and Demon? Am I Tao? Is He Demon?" Rahu sneered.

"You are the demon, He is the way," Luo Zu corrected.

"What is demon? What is the Tao? Aren't demon and Tao one and the same?" Rahu argued.

"Heaven and earth give rise to yin and yang, male and female, black and white. The Dao is born from chaos and nothingness. So where does the demon come from? Yin and yang are one, so how can the Dao and the demon not be one?" Rahu wanted to continue arguing.

"This humble one is utterly ignorant of the mysteries within. I only know that there was a struggle between the Dao and the Demon in the past, and that the Dao Ancestor prevailed, causing the Demon Ancestor to cease to exist. I wonder if the Demon Ancestor remembers the difference between the competition between you and the Dao Ancestor in the past and the current struggle between the Lich and the Demon?" Seeing that one test had failed, Luo Zu restarted another round of probing.

"Fellow Daoist Luo Zu, I now also call you fellow Daoist, so why would I call you fellow demon?" Luo Hou asked in return.

"No, that hasn't happened before," Luo Zu could only reply in agreement.

Luo Hou then added, "Fellow Daoist Luo Zu's affections are quite active in my Candle Dragon River. I wonder if you would be interested in coming to visit as well?"

Luo Zu dared not accept this invitation; who knew what Luo Hou would do to him once he entered this hazy river of time?

"The Demon Ancestor is so willful, may I ask if he knows where the Ancestor is now? Will He discover you?" Luo Zu asked again.

Rahu replied, "How do you know whether I have also been turned into a puppet by that scoundrel Hongjun?"

Upon hearing this, Luo Zu's heart sank. These powerful figures were known for their irrational strength, and who knew if Luo Hou's words were true?

Who knows, the Dao Ancestor might want to create another river of time to conduct a different comparative experiment.

"How does Fellow Daoist Luo Zu know which dimension the River of Time is in?" Luo Hou suddenly asked.

"Isn't it right here in the chaos?" Luo Zu replied casually.

This isn't entirely nonsense. The primordial world was in chaos, so wasn't the river of time in the primordial multiverse also in chaos? It's just that Luo Hou asked which dimension.

"Fellow Daoist understands my meaning. There's no need to pretend to be confused. The establishment of dimensions is not something that happens naturally. It is the product of countless Great Daos weaving and weighing each other." Luo Hou revealed this information to Luo Zu at this moment.

"I hope the Demon Ancestor will offer more guidance." Luo Zu followed the situation and addressed the matter at hand.

"There are nine dimensions, but time is not in any of them. Otherwise, if it could penetrate all the dimensions, then those higher dimensions would collapse because they would have to bear so many fellow Daoists."

"Therefore, time has its own dimension, neither within nor outside the nine dimensions." Rahu's words only added to the confusion.

However, Luo Zu was no ordinary person and would not be confused by this. As a Taiyi, he had cultivated for a long time and had an understanding of spacetime dimensions and the nine dimensions. Therefore, he also understood Luo Hou's meaning: left and right are like waves that sweep across the water surface without leaving a trace.

"Time and space are the most mysterious things. There shouldn't be any great Dao in them, but it's like the Great Dao of Limitlessness..." Rahu paused here.

Luo Zu understood; this was a subtle dig at him, after all, he was the Lord of the Limitless Dao. (End of Chapter)
