The primordial era began with the Upper Cave Man.

Time is becoming increasingly worthless, Luo Zu has often lamented in recent years.

Moreover, the act of tracing back to the past always made him feel like an "archaeologist".

Because such rubbings are not simply a return to the past, but a thorough review of everything that happened during that long period of time, leaving no detail unexplored. Although some history may be covered up, distorted, or even intercepted by certain important figures, in general, the vast majority of the history of that period will still be unearthed by him.

During this excavation process, he had to create three more great universes within the Primordial Spirit Universe, each filled with the thoughts of intelligent giants, specifically for storing this information.

The amount of information contained within is enormous, and this doesn't even include the "future" tributaries of the past timeline. However, these tributaries have all been eliminated, so the corresponding information could not have been unearthed by Luo Zu.

However, sometimes we "accidentally" unearth some "future" branches from the past, and then obtain some surprising information from them.

For example, the shady past of certain important figures selling hooks...

Or perhaps a great figure hidden in the dust of history.

Even the physical remains of some deceased great figures before their reincarnation.

Some innate spiritual treasures concealed their physical forms, and then their primordial spirits reincarnated and began to cultivate again, but failed to achieve enlightenment and returned to retrieve their physical forms.

During this long period of fifty million years, Luo Zu discovered fifteen innate spiritual treasures and hid his own body in the "future" branch of the abandoned past timeline.

These innate spiritual treasures are of good quality. Even though their primordial spirits took away half of the innate spiritual restrictions, they are still of a grade no lower than that of mid-grade innate spiritual treasures.

Unfortunately, the primordial spirit has already shed its shell. Even though its grade is no lower than that of a mid-grade spiritual treasure, its power may not be able to reach the level of a mid-grade innate spiritual treasure.

Luo Zu did not take these innate spiritual treasures; who knows if they were bait, specifically used to catch a big fish like him.

After all, there are quite a few ruthless people in the prehistoric world, and quite a few of them use themselves as bait. Among the Wu and Yao clans, there are many Golden Immortals and Taiyi who rely on the power behind them to use themselves as bait to lure a large number of their own people to come and eliminate them.

In short, neither the Lich nor the Lich race has a very high floor.

Otherwise, he could not have become the overlord of the primordial world.

Besides these special cases, Luo Zu also discovered that some ancient beings were hidden in the annals of history, cautiously avoiding the reckoning of their enemies.

For example, a certain dragon ancestor who wishes to remain anonymous, a certain phoenix ancestor who also wishes to remain anonymous...

These once powerful figures, who led the way in an era, are now all huddled together, barely surviving.

Logically speaking, with their abilities, they shouldn't be so humble, but they've offended many important figures these days, so they have no choice but to keep a low profile.

Moreover, their versions of Taoist practices have become outdated, especially after the entire system became rigid. It's difficult for a large ship to turn around, and with such accumulated problems, they can no longer keep up with the changing times and the replacement of Taoist practices.

If you fall behind at one step, you fall behind at every step, and gradually these old guys will even be unable to keep up with the younger generation.

Even now, with the iterative updates of cultivation methods, the cultivation realm is actually declining.

"The past is truly wondrous, to the point that we can still witness such secrets," Luo Zu remarked with deep emotion.

In recent times, in addition to tracing back to the past, Luo Zu has also been studying the discovery of the battle between the seven Taiyi masters.

One of the major discoveries was the killing immortal technique refined by the demonic blade of the chosen one, which he personally selected.

This guy kills without blinking an eye, he kills gods and ghosts alike, he doesn't care what you are, as long as you stand in his way, he won't hesitate for a moment to kill the enemy, if he lets him live, he will die.

The Demon Blade's ideology, nurtured by the unique environment of that vast universe, was indeed somewhat extreme.

However, Luo Zu thought it was too extreme. There were a thousand ways to deal with enemies, so why kill so many people?

Luo Zu had already brought the Demon Blade out of that vast universe and taken him in as a disciple.

However, after accepting the Demon Blade as a disciple, Luo Zu noticed that something was wrong with him.

More accurately, there is something wrong with the path of slaughter.

The Slaughter Path cannot be considered an innate path, but it originates from the Destruction Path. This path is an innate path, and it is currently occupied by the Styx Ancestor.

However, the path of slaughter itself has great potential, and now the Free Heavenly Demon Mara has used it to achieve the Taiyi realm.

In the future, it may be possible to use this to prove the Great Luo, but the Dao is ever-changing. Now, the Blood Sea's position in the prehistoric world is precarious. Above it is the Sea of ​​Bitterness, which fights against the negative aspects of all living beings, and below it is the Netherworld and Yellow Springs, which steal the souls of the living. It even has to give up its title as the lowest place in the prehistoric world. The Blood Sea now has to live a very frugal life.

If it weren't for the Styx Ancestor creating a separate multiverse and using it to stabilize the Blood Sea, his old lair might have slowly fallen into the Netherworld and sought refuge with the Earth Goddess.

However, the demonic blade that Luo Zu acquired had nothing to do with the Styx Ancestor, nor even with the Free Heavenly Demon Bo Xun, who also belonged to the Great Dao of Destruction.

It is related to the legendary Rahu.

This being, who only exists in "rural novels," was a peerless figure who could rival the Dao Ancestor in the pursuit of Dao. If He had won back then, it's possible that He would be the one sitting in Zixiao Palace now.

The reason why he could be associated with the Demon Blade was because when Luo Zu was fighting, he temporarily lent him the Xishui Sword. The Xishui Sword contained the Zhuxian Sword Formation that Luo Zu had passed on to him for refining. The Demon Blade was not bad in talent, and he actually learned this technique when he used the Xishui Sword.

When Luo Zu learned of this, he immediately felt a sense of unease. His heart, which had never skipped a beat in countless ages, suddenly skipped three beats, as if giving him a warning.

He became alert, and at that moment, most of his attention was focused on the demonic blade itself, rather than on the Taiyi battle.

However, the Demon Blade was "too powerful." Even without the subsequent help of its master, it continued to kill, and with the help of luck and strength, it directly won the championship of this battle.

In order to prevent the Demon Blade from falling into the hands of others and being used against Luo Zu, he had no choice but to take it as a disciple and, incidentally, destroy the Great Thousand Universe.

Moreover, he didn't hypocritically rescue the creatures. After all, he had watched with his own eyes as the demonic blade killed billions of lives without stopping it, so why should he pretend to save all living beings in the universe?

After receiving the Demon Blade, he used it to deduce the Great Dao of Slaughter related to him, and Tuoying's past cultivation gradually reached the level of 50 million years ago.

Then he unexpectedly discovered a "future tributary" of the abandoned past.

But now, through his research on the Killing Road, he has discovered the unusual nature of this tributary.

It seems He hasn't stopped flowing into the past, hasn't dried up, and continues to flow slowly... (End of Chapter)
