Chapter 415: Three Hundred Years Later

The true body remained stationed at the headquarters in the Azure Sky World, while the two Primordial Spirits explored separately.

This was the safest method.

Whether it was the Solar Nascent Soul or the Taiyin Primordial Spirit, its combat power was not much weaker than Lin Yuan's true body.

Even if it fell, the true body could condense it back into existence with a single thought.

It couldn't be safer.

Although the level of the Boundless Void was inferior to the Main Universe.

But Lin Yuan never underestimated it; at least the legendary Tier 9 Evil Gods could pose a slight threat to him.

Whoosh.

Whoosh.

Under Lin Yuan's watch.

The Solar Nascent Soul and Taiyin Primordial Spirit immediately left the Azure Sky World.

"Void Secret Realm?"

Lin Yuan's Solar Nascent Soul followed the coordinates within the scroll, rapidly heading toward the location of the Void Secret Realm.

With Lin Yuan's attainment in space-time, the distance from the Azure Sky World to the entrance of that Void Secret Realm would take the Black Demon Pavilion Master five or six days of flying, but Lin Yuan could arrive in just a short while.

"The Void Secret Realm even obscures the memories of entering it, preventing them from being passed outside. What kind of place is this?"

Lin Yuan was somewhat curious.

The Main Universe's Human Civilization could also achieve this, but Human Civilization had Nine Supreme Experts stationed there.

"Also, what kind of benefits can one actually obtain by killing Void Creatures?"

The information within the scroll did not mention any benefits, but Lin Yuan deduced that there definitely were some.

"Could it be the Physical Body of the Void Creature itself, or some kind of Materials treasure?" Lin Yuan thought to himself.

This was also the most normal deduction. Just like how Lin Yuan could study the Physical Body of an Evil God after killing it, the Physical Body of a Void Creature could similarly be studied.

Very quickly.

Lin Yuan stopped.

"Arrived."

Lin Yuan looked toward the Boundless Void in front of him.

But from the exterior, the Void Realm before him had no difference from the Void Realm in other places.

However, relying on the scroll token, Lin Yuan vaguely sensed that a mysterious space was hidden deep within the Void Realm.

To be precise, it was the entrance to the mysterious space.

That is, the entrance to that Void Secret Realm.

"This?"

Lin Yuan's expression changed slightly.

Even without relying on the scroll token, Lin Yuan could perceive the existence of the Void Secret Realm with his own space-time comprehension.

But the more it was like this, the heavier Lin Yuan's heart became.

He could feel that the vastness of the Void Secret Realm could almost be said to be another spatial layer of the Boundless Void.

Moreover, the 'entrance' before him right now was only one of the many entrances to the Void Secret Realm.

Just like the Profound Yellow Secret Realm of the Main World, this Void Secret Realm should have many entrances.

"If I didn't rely on this scroll token, I still wouldn't be able to enter."

Lin Yuan thought to himself, "Estimatedly, only the fifth-level Realm of the Space-Time Fusion Rule would be able to forcibly enter the Void Secret Realm without the aid of a token."

Lin Yuan exclaimed inwardly.

"Then how high must the attainment in the Space-Time Fusion Rule be for the entity that originally created this Secret Realm? Sixth-level Realm? Supreme Powerhouse Domain?"

Lin Yuan did not dare to have any contempt in his heart.

Although many Secret Realm belonged to naturally formed ones, since this Void Secret Realm formed a scene where one could enter directly with a token, there must be Acquired factors involved.

"Let's go in and take a look."

Lin Yuan immediately activated the scroll, and suddenly a suction force surged from deep within the Void Realm, pulling Lin Yuan inside.

If it were his true body, Lin Yuan naturally wouldn't dare to easily enter an unknown Secret Realm like this, but with just a Solar Nascent Soul, he could naturally try and make mistakes as much as possible.

Hum.

Next moment.

Lin Yuan arrived in a vast space.

There was no end in sight in all directions, and black mist occasionally floated in the sky.

"Is this the Void Secret Realm?"

Lin Yuan was very cautious, immediately hiding deep within multiple spatial layers.

Within the Void Secret Realm, it was as if another Boundless Void existed, with numerous spatial layers.

"Where are the Void Creatures?"

Lin Yuan looked out, but did not discover any signs of biological activity.

"Let's explore slowly."

Lin Yuan began to carefully choose a direction to go deeper.

The Void Secret Realm was too vast. Although Lin Yuan could span long light-years in a single step, that was under the condition of traveling.

To find Void Creatures, naturally one had to search bit by bit; otherwise, if Void Creatures were hidden in the middle of spanning long light-years, they still wouldn't be discovered.

One month after Lin Yuan's Solar Nascent Soul entered the Void Secret Realm.

Hum.

Lin Yuan was moving rapidly, but viewed from the outside, it did not cause the slightest commotion.

And tens of thousands of miles away, beneath a black Mountain Peak, a behemoth was staring at the flying Lin Yuan.

Lin Yuan's true body was hidden within multiple spatial layers, but this behemoth could clearly sense the aura of the multiple spatial layers and lock onto Lin Yuan's position.

The behemoth was slowly approaching Lin Yuan.

"That's a Void Creature?"

While maintaining his movement, Lin Yuan had naturally discovered that behemoth approaching him long ago.

With Lin Yuan's perception, even without actively unfolding the World phantom, a radius of billions of miles was as clear as looking at the lines on one's palm, and the possibility of being ambushed did not exist.

"It is indeed significantly different from an Evil God."

Lin Yuan thought to himself. The Void Creature he sensed felt no different from a beast, completely devoid of any rationality, and even approaching while concealing its aura was done purely on instinct.

As for Evil Gods, although most Evil Gods occasionally went mad, they at least possessed rationality.

"It's here."

A moment later, that behemoth had already approached within a hundred miles of Lin Yuan.

Next moment.

This behemoth stopped and no longer approached.

"Hmm?"

Lin Yuan did not immediately strike, instead wanting to see what methods the Void Creature had.

Hum.

An illusory world shrouded down, and Lin Yuan's mental will instantly plunged into layers of illusions.

The scene before Lin Yuan was no longer in the Void Secret Realm, but inside a palace, where charming beauties were approaching one by one, trying to seduce Lin Yuan.

"Illusions?"

Lin Yuan didn't care at all. With his methods, even without borrowing any Soul-defensive secret treasures, he could easily block these illusions.

"Break."

Lin Yuan's thought turned into a sharp blade, easily tearing apart the illusion world before him.

At this moment, that Void Creature was planning to approach, wanting to take the Opportunity to attack before Lin Yuan broke free from the illusion.

It was just that the speed at which Lin Yuan recovered his sobriety was too fast; before this Void Creature could even start approaching again, the so-called illusion had already ended.

"If it's only illusion methods, then stay."

Confirming that this Void Creature did not have the strength to threaten him, Lin Yuan directly attacked.

With a bang.

Majestic World Power surged, and space faintly distorted. Before that Void Creature could even react in time, it fell into the palm of Lin Yuan's hand.

This Void Creature was at least dozens of miles large, but right now under the heavy spatial suppression, it became pocket-sized, continuously struggling in Lin Yuan's palm.

"Hmm?"

"Unable to search the Soul? No specific memory images?"

Lin Yuan attempted a Soul search, but it was of no use.

The degree of chaos in the thinking of these Void Creatures was similar to that of beasts, unable to even store specific memories.

"Kill it directly."

After studying for a long time, Lin Yuan didn't gain much, so he simply followed the information within the scroll and directly killed this Void Creature.

Hum.

At the moment this Void Creature died.

Its Physical Body suddenly began to turn illusory.

"This?"

Lin Yuan frowned.

Once dead, the Physical Body turns illusory and disappears?

Not even leaving him the Physical Body?

Then what were the benefits of killing Void Creatures?

Before Lin Yuan could continue thinking, the completely illusory Void Creature shattered into strands of aura, which then merged into Lin Yuan's body.

"Hmm?"

Lin Yuan was about to activate World Power to expel it. Before its use was determined, such unknown aura could not be absorbed no matter what.

But even World Power could not touch those strands of aura.

In an instant.

Those strands of aura disappeared within Lin Yuan's body.

"Eh?"

Lin Yuan seemed to feel something, "My mental will has improved by a section, is it because of this Void Creature?"

Lin Yuan found it hard to believe.

There were only a few ways to improve mental will.

First, slowly improving over long years.

Second, experiencing various tortures and pains.

For example, when Lin Yuan comprehended that severed body part from the Supreme Powerhouse, enduring the ubiquitous mental will coercion, his own mental will was also slowly improving.

But this method of improving mental will, as Lin Yuan's mental will increased, became increasingly weak in effect.

But now?

Lin Yuan abruptly discovered that after killing this Void Creature, his mental will had actually improved by a section.

This, this, this was simply incredible.

There was no need to say much about the importance of mental will.

It was the core of the Soul. The stronger the mental will, the higher the blessing to all aspects.

And breaking through to the Ultimate Realm also required a strong mental will. If the mental will did not meet the standard, it simply couldn't block the backlash and obstruction from the River of Time.

Most importantly.

Compared to treasures on other material levels.

The improvement of mental will could be directly brought back to the Main Universe.

After all, when Lin Yuan traversed and descended, his main body was his mental will. When the traversal ended and he returned to the Main Universe, what went back was also his mental will.

And during this period, if the mental will gained improvement, it could naturally be brought back perfectly.

Azure Sky World, deep within the Martial Hall.

Lin Yuan, who was originally cultivating and comprehending, suddenly opened his eyes.

"My mental will has indeed increased."

A trace of shock appeared on Lin Yuan's face. With the various intelligence information of the Main Universe's Human Civilization, he naturally knew how difficult it was to improve mental will.

According to the experience summarized by Human Civilization, when a Tier 11 powerhouse impacted the Ultimate, one of the many threshold conditions was mental will, meaning the mental will index had to reach ten million.

This was the threshold. The higher the mental will, the greater the help in impacting the Ultimate.

Lin Yuan had originally been somewhat worried about how to improve his own mental will.

Compared to special life forms like the Four-Armed Divine King, Lin Yuan's biggest shortcoming was that he was too young and had experienced too little time, causing his mental will to lag behind somewhat.

"A great Opportunity."

"That Void Secret Realm is a great Opportunity for me."

Lin Yuan's gaze was slightly burning.

"The main task of the Solar Nascent Soul in the Void Secret Realm is to find more Void Creatures and then kill them to improve mental will."

Lin Yuan immediately made a decision.

The true body comprehended the 'World' Divine Ability imprint, comprehended the Space-Time Fusion Rule, and comprehended many other Fusion rules.

As for the two Primordial Spirits, the Solar Nascent Soul would wholeheartedly search for Void Creatures.

While searching for the numerous worlds of the Boundless Void, the Taiyin Primordial Spirit concurrently comprehended rules and so on.

Just like that.

Time passed quickly.

In the blink of an eye, three hundred years later arrived.
