290: The sky turns

At first, it wasn't obvious enough, but the further it went, the more apparent the trend became, similar to these mass-produced Ancestor Realm cultivation techniques.

It was as if someone was observing the cultivators' conditions in real-time and making improvements based on that.

By the late Hundred Ancestor Era, this kind of improvement had reached an extremely sophisticated level.

That period was also when Ancestor Realm powerhouses appeared most frequently and in the largest numbers.

Especially at the end of the Hundred Ancestor Era, there was even a phenomenon where the Eight Ancestors were born in the same period.

It's just that later, for some unknown reason, the other party seemed to have suddenly vanished without a trace, as if they had never taken any further action.

But what was the other party's goal?

To cultivate a large number of Ancestor Realm powerhouses and then have them merge with the heavens and earth.

Doesn't this feeling resemble… Chen De conducting an experiment?

The Hundred Ancestors merged with the heavens and earth, and after reaching a certain degree of integration, a qualitative change occurred once a critical point was reached.

And what the other party needed might have been certain phenomena during the qualitative change.

After recording the relevant data and experimental results, the experiment could be considered complete.

However, this was just Chen De's speculation.

Who could have such a grand scheme, cultivating over a hundred beings comparable to the Heavenly Imperial Realm?

Making them sacrifice themselves, merging with the heavens and earth, just for the sake of an experiment.

Especially considering that experiments rarely yield results from a single attempt.

Even those elementary school-level playful experiments need to be conducted three times for comparison.

And the more rigorous the experiment, the more repetitions are usually required.

If the other party was truly conducting an experiment, there are some things Chen De simply dared not imagine.

Standing outside the Bai Zu Ruins, Chen De frowned and began pacing around.

This was a habit of Chen De's; whenever he encountered something that required deep thought.

Chen De would go to a quiet place and walk in circles around a certain area.

After Chen De had walked for about thirty or forty circles, he stopped.

His hand moved swiftly across his body, separating out a full two-thirds of his black liquid.

This was the maximum amount of black liquid Chen De could separate while ensuring his combat strength.

Based on the current analysis, if it was truly an experiment, Chen De was ninety percent sure that the other party was no longer here.

And the remnants left by the other party might provide great help to Chen De at this moment.

After separating this portion, Chen De didn't hesitate and directly threw him in.

On the other side, Xiao Dou was already waiting inside to rendezvous with Chen De.

After the two black liquids gathered, they randomly found a spot and, using it as a starting point, spread throughout the entire Bai Zu Ruins.

According to Chen De's speculation, if such an experiment truly existed.

Then the other party's stronghold was most likely within these Bai Zu Ruins.

Chen De only needed to search inch by inch, space by space.

With his Evil God Essence's characteristics, as long as it was inside, he could definitely ferret it out.

And so, a day passed…

Three days passed…

Five days passed…

Ten days passed…

Chen De had searched every single corner of the entire Bai Zu Ruins, from inside out, and found nothing amiss.

How could this be? Had he guessed wrong?

Many of Chen De's ideas actually lacked sufficient factual evidence.

Sometimes, looking at it from a different perspective, these clues connecting together also made perfect sense.

Had he really guessed wrong?

At this moment, Chen De looked again at the spatial portal of the Bai Zu Ruins.

That was the original portal, not the passage Chen De had opened by unconventional means.

Currently, this spatial portal still gave Chen De a very complex feeling.

It was as if this wasn't a single spatial portal, but rather two or more overlapped together.

Upon realizing this, Chen De's eyes lit up, and he quickly began to study this portal.

Three days later.

With Chen De's powerful spatial talent and three days of non-stop research.

Chen De finally confirmed that this was not one spatial portal, but two, just overlapped together.

What Chen De had intercepted before was the fluctuation of the Bai Zu Ruins' spatial portal.

It wasn't a coincidence, nor was it bad luck.

The two spatial portals were designed with extreme precision; the spatial fluctuation of the other segment was perfectly overlapped by that of the Bai Zu Ruins.

Anyone who came, without special methods, could only intercept the fluctuation of the Bai Zu Ruins' spatial portal.

And thus, could only enter the Bai Zu Ruins.

But Chen De was different; the Heaven Forsaken Demonic Spider was the strongest demonic beast race in terms of spatial talent in the Four Profound Heavens, and all of them were pure-blooded.

With such ability, it was fine if Chen De didn't notice anything wrong, but if he did, he naturally had a way to decipher it.

The method was also very simple; Chen De didn't have the corresponding password for the spatial portal, which was the activation method.

So what Chen De still needed to do was first intercept a segment of the spatial portal's fluctuation.

He would place it in a specially designed space, preventing it from continuing to spread.

Then Chen De would use his ability to separate the two spatial fluctuations.

Next, Chen De would use the other fluctuation to open a passage of the same style as the previous Bai Zu Ruins.

If the main entrance was difficult to use, then he wouldn't use the main entrance.

He collected the black liquid from the Bai Zu Ruins and cast it into this new spatial portal.

Upon entering, Chen De saw that it was just a small to medium-sized area inside.

Its actual size was only equivalent to that of a basketball court.

It wasn't a high-tech research institute as Chen De had imagined.

On the contrary, it was very primitive, just like normal buildings outside.

There were some scattered papers inside, and it was obvious that anything left behind wouldn't be something important to anyone.

But out of curiosity, Chen De still had Xiao Dou go over and pick one up to read.

"Regarding the cultivation technique practiced by Ancestor Lie, 'Chongguang Bailie Jue', the effect after merging with the heavens and earth is poor, but the time to achieve Ancestor Realm is faster; subsequent cultivation techniques should be adjusted…"

He had already guessed it, so seeing the concrete evidence wasn't as shocking as he had imagined.

Picking up a few other papers, the content was largely similar.

All of them were analyses of a certain Ancestor Realm's growth path, performance after merging with the heavens, and optimizations or adjustments to subsequent cultivation techniques.

Not only that, Chen De also found something similar to a serial number in a certain spot here.

This Sky Vault Battle Shift was indeed a huge experimental ground.

Next, after collecting all the papers, Chen De searched around here again.

He actually found a cultivation technique here; Chen De held it in his hand and looked at it.

A hint of surprise flashed in his eyes, yet he also felt it was only natural.

The name of this cultivation technique was 'Sky Vault Battle Shift', also known as 'Sky Vault Nine Revolutions'.

This cultivation technique was divided into nine levels: Channel Opening, Qi Sea, Origin Core, Divine Infant, Earth Fiend, Heaven Profound, Universal Cycle, Pi Ming Realm, and Ancestor.

But that wasn't the point; it was because this cultivation technique was a genuine cultivation method for the Four Profound Heavens martial artist system.
