The killing intent formed into almost an oppressive force, attempting to suppress Cain before the fight even began.

Cain, however, was indifferent. Using his Soul Sense, he quickly absorbed pure World Source Law essence into his mental psyche.

For Sky Ruler's geniuses, attempting such a feat would be an immense hurdle. Their attainment with Source Law would barely be ordinary at best. Most would still just be at the Threshold Sucess stage.

The Divine Origin geniuses wouldn't fair that much better as well.

They would merely be above the Ordinary Stage, the Adept Stage.

For those geniuses, controlling World Source Law would still be a great task requiring great focus.

But, how could these stipulations apply to Cain?

Not only had he reached the Advanced attainment level, a stage that generally requires dozens of years. But he had also achieved Large Success!

That wasn't to say it was entirely smooth controlling pure World Source Law essence. There was still a noticeable restriction when comprehending the essence.

However, it was barely negligible to Cain.

A moment later, Cain had already grasped a good portion of World Source Law's essence.

Waves of powerful aura frantically rushed out of Cain, colliding with the surrounding killing intent aura.

With only a faint sound, the killing intent aura was smashed to pieces.

In response, the phantom's killing intent wildly surged. Its aura began to intensify as it similarly pulled World Source Law essence into its body.

At the same time, Cain's palm snapped open. He was second away from gathering a mass storage of World Source Law essence into his palm.

Suddenly then, a thought streaked into his mind.

'I can't use any of my other energies. But can I use my Chaotic Emerald? It is connected to my Soul, and not even a Divine Ruler can perceive its energy. Let's test it out.'

A brilliant green flash sparkled within Cain's purple. His Soul energy split off, going deeper within his Soul's Core.

In an instant, Cain linked to his Chaotic Emerald.

Stimulating it with Soul energy, Cain promptly found joy. There was no restrictive force halting his Chaos energy!

Cain was able to flawlessly pull out 20% of Chaos energy, revolving it throughout his internal body.

Of course, since it wasn't fusing with any other energies, the effect of Chaos energy was significantly weaker. His combat prowess would at most reach the late-tier of Middle Stage Sky Ruler.

However, in a place where everyone was completely suppressed, it was still an immense advantage!

Chaos Spirit Force-Open!

A burst of incredible energy frantically discharged. Cain's aura exploded to dangerous degrees.

Green lights flickered out of Cain's body as a faint green aura shrouded him.

Even though Heavenly energy can restrict Divine Star warriors and even prevent Divine Ruler from forcing their way in the quasi-mystic realm, it was unable to do anything to Chaos energy.

For a brief moment, Cain honestly wonders just what the hell is this Chaotic emerald.

This item just seems far too powerful to be left unchecked. Without this, his cultivation journey wouldn't be anywhere near as smooth.

Still, despite his questions, Cain forced it all down, turning his attention on the Law Phantom.

At this point, the Law Phantom had its white engulfed eyes bursting wide open.

It stared at Cain as if it was a freak.

A moment ago, their aura was utterly equal. And now, it was suppressed to an overwhelming degree!

At the immediate threat of danger, the Law Phantom erupted with all its strength!

World Source Law essence converged around it, rapidly forming into a pure white essence barrier.

Cain didn't dare to wait a moment more. Before the Law Phantom formed another move, he struck out.

His open palm sucked in World Source Law essence, creating a long essence Sword. The essence Sword was similarly shrouded in a faint green glow. Chaos amplification shrouded its entirety.

Flicking his wrist, Cain shot out the essence Sword.

A streak of white mixed with faint green tore through the area. All in a moment, the essence Sword soared a 100-meter distance!

The Law Phantom couldn't react. Its generic face twisted in horror, wanting to dodge out of the way.

But it was too late.

'Ka-Cha!'

The essence barrier shattered like fragile glass. The essence Law Sword tore right through it without any obstruction, piercing right into the Law Phantom's skull.

Without any suspense, the Law Phantom couldn't react.

It was promptly killed by the Law essence Sword; a moment later, its head burst into streams of World Source essence.

Its body soon joined in, imploding into sparkles of twinkling white lights.

Cain had a slight grin, feeling greatly invigorated for the Nightmare Realm.

Truthfully, he would still be able to win that fight easily without Chaos energy. But he would need to expend a considerable amount of Soul energy to fight at full power.

Soul's Core may have an infinite supply of Soul energy reserves. But it is very possible to run out.

In that situation, a Martial cultivator would have no other choice but to wait until their Soul's Core replenishes a reasonable amount of Soul energy.

And even then, the Soul's Core would be in an irritable state. It hasn't experienced any proper soothing rest, which can cause a tremendous drop in combat prowess.

Cain was attempting to make it as far as possible in the Nightmare realm. He didn't care about overpowering since it uses the least amount of energy possible.

Moreover, the later rounds will throw far more powerful Law Phantoms at him. It was best to get sufficiently prepared for that.

As Cain mused to himself, two sudden white flashes sparked right in front of his face. Blinking his eyes, he instinctively opened his palm, feeling an object land in each of them a moment later.

Opening his eyes back open, greed immediately flared within Cain's pupil.

His left hand was holding a bright orange crystal that felt incomparably smooth to touch. It was also exuding a great source of purest Qi energy.

While in his right hand was a beautiful golden crystal that had similar smooth properties. This crystal was discharging an incredible source of Source Law essence.

Cain knew precisely what these items were. 'The orange crystal is a crystal Sun bead. And the golden crystal is a Law Crystal Core! With the crystal Sun bead, my Martial cultivation can shave off even months of time all at once. And with the Law Crystal Core, my mental psyche would experience greater nourishment, and my Minor Laws will have rapid accumulations, extending up to months!'

Both of these resources shouldn't be taken lightly. Not even his grand Huang Dragon Holy Family has a plentiful supply of either resource.

After all, both crystal Sun Beads and Law Crystal Cores are even helpful to Divine Paths cultivators!

'No wonder so many come here at every opening. Just one crystal Sun Bead can perfectly fuse in any Divine cultivator's Inner World, enhancing it by weeks of development. While the Law Crystal Core essence is a great shortcut for Divine Source Laws. Our cultivation can truly soar.'

Cain was filled with eager anticipation. His fists were subconsciously gripping themselves in burning excitement.

And as if responding to Cain's call, the power of space suddenly shifted around him.

The next moment, Cain had teleported into another white area.

Immediately when appearing, Cain felt an essence wrapping around his body, attempting to restrain him.

Law essence Chains had already wrapped around Cain's body. And compared to the previous Law Phantom, this one's strength was notably higher.

Attacking without any warning would understandably cause a fluster.

But Cain had unending confidence backing himself up. A sneer curled his lips, his Soul energy linking to the Chaotic Emerald once again.

Chaos energy burst from Cain, the faint green aura vaporizing the Law essence chains into wisps of white light.

Freed, Cain then waved his hand, shooting out several Chaos amplified Law essence Swords towards the surprised Law phantom.

With a soft pop, the Law Phantom was turned into white lights.

With Chaos Spirit Force amplifying his prowess by at least 10x, Cain was simply too powerful for the early rounds.

Of course, if he didn't have great control, all this power would go to waste.

For now, however, Cain was an unstoppable force.

When killing the Law Phantom, Cain received his rewards before getting instantly teleported to the next round.

What ensured was a repeat of the last two rounds.

Instantaneous killing with little resistance.

From the third round to the fourth round, Cain killed with a casual wave of his hand.

It was only at the fifth round where things became a bit more intriguing.

As he appeared in the fifth round, Cain was once again ambushed by Law essence Chains. The Chains powerfully constricted his body, having considerably more strength than the last four rounds.

And at the same time, a second Law Phantom attacked!

Indeed, for the fifth round, a challenger would need to deal with two simultaneously.

The Law Phantom surged all of its essence, clasping both of its palms outwards as it blasted out a large Law essence Sword.

The large Law essence Sword covered a towering height of dozens of meters, essentially blocking out all of Cain's escape route.

He needed to face both attacks head-on!

But still, Cain didn't become flustered.

Surging his Chaos Spirit Force, Cain coated one of his hands with World Source Law essence and then gripped the essence Chains.

Shattering sounds echoed out as Cain forcefully crushed the essence Chains to bits.

Simultaneously, Cain's second hand shot out an equally large amplified Law essence Sword.

'Bang!'

Source Law essence clashed, erupting in a powerful storm of energy.

The two Law Phantoms had no other choice but to slightly retreat, or else they would be gravely injured by the shockwaves.

'Perfect!' A cold shine twinkled Cain's eyes.

Amplified by Chaos Spirit Force, Cain shot out right towards the Law Phantom that had set up the previous restrictive chains, his body soaring like the wind.

All in a moment, he neared just a few meters from the Law Phantom.

Cain flicked his wrist, discharging a Law essence Chain at lightning-like speeds.

The speed behind the Law essence Chain was slower than the Sword. But the power it exuded was significantly higher!

The various forms of these Law essence attacks are a subconscious move on Cain's part. Each form holds its own unique properties for situations.

Cain had never practiced with this type of attack before. But because his attainment level of the Source Law Path is high, he had an innate feeling on what would be the best option. It was innateness that was engraved into his very Soul!

The Law Phantom did indeed see the Law essence Chain soaring towards its face. In a vain attempt, it clasped its hands together, spewing a vague essence barrier.

The defense was, however, futile.

The Law essence Chain shattered the barrier like glass and continued on to tear right through the Law Phantom's head.

The Law Phantom immediately imploded into wisps of white lights.

At the same time Cain killed this Law Phantom, the other one was already closing in on him.

The second Law Phantom blitz out with incredible speeds, a spiked shield extending from its palm, covering the front of its body.

The spikes on the shield faintly shimmered, evidently charging up an attack. Its power considerably rises, reaching slightly threatening levels.

Cain merely narrowed his eyes and gathered 70% of his Soul energy strength.

Punching out with his fist, Cain exerted far more force when discharging the Law essence Sword.

'Bang!'

The Law essence Sword shredded the Law Phantom's defenses, instantly destroying its entire body into light wisps.
