It was extremely tough and radiant.

His right eye seemed to have turned into a blazing sun!

Beside the red-headed ghost, Aiden felt like he could melt and dissipate at any moment!

How could this be?

A question popped into his mind.

An intense scorching fiery energy as such was the most effective at countering ghosts and they would want nothing more than to avoid it – how could the red-headed ghost possess such a method?

Could it be that he was not a ghost?

Suddenly, Aiden felt a sharp pain in his right eye!

It was as though something was going to fall from his socket.

He could not stop it even with his eyes closed!

"Ah!"

Aiden yelped in pain as his right eye swelled uncontrollably as though it was about to explode!

His body shuddered and finally, he opened his eyes, unable to hold on any longer.

His right eye had turned a sinister shade of white as well.

It was completely white!

It was as though something was floating within and was fused with his right eye.

The glow in the red-headed ghost's right eye dissipated as he glared at Aiden's right eye intently while nodding. "Indeed!"

The red-headed ghost curled his finger.

A jade-white cobblestone that sparkled and glowed fell out from Aiden's right eye and hovered in midair.

The swelling sensation vanished completely.

As though a weight was lifted off his shoulders, Aiden fell to the ground and sat limply while panting heavily.

"This stone.."

According to his memories, this white stone was retrieved from an old ruin but it could not be stored in a storage bag and he did not know what purpose it served either.

When Aiden picked it up, the stone vanished bizarrely!

Immediately after, he felt a sharp pain in his mind and almost fainted. Thereafter, a secret skill appeared in his mind – the Illumination Sword Formation.

At that time, he had a hunch.

It seemed like that stone had burrowed into his body!

To think that it would fall out from his right eye now!

The red-headed ghost held the white stone with his fingertips and rubbed it gently with a forlorn look, as though he had picked up a treasure.

"What's that?"

Aiden could not help but ask.

"Legend has it that in the depths of the universe's void currents before life was born, everything was chaos. As time passed by, chaotic, opposing energies were created from the chaos."

"At their extremities, the powers of Extreme Dark and Extreme Light gathered endlessly, forming two terrifying existences known as the Extreme Dark Illumination and Extreme Light Nether Glow!"

The red-headed ghost's voice sounded, as though he had passed through time and was describing obscure secrets.

"The powers of the Illumination and Nether Glow were so frightening that they shrouded the universe and extended through the trichiliocosm. The sun and moon of the world are created from a trickle of power from the Illumination and Nether Glow."

"A trickle of power?"

Aiden was shocked.

Be it the sun or the moon, the power they contained was something that Aiden would never be able to reach given his current training realm.

The only way he could train with the essence of the sun and moon was after he trained an Essence Spirit and turned into a fiend demon.

The power of the sun and moon was extremely massive and endless.

But now, the red-headed ghost was actually saying that the sun and moon above them was merely created by a trickle of power from two frightening entities!

The red-headed ghost laughed. "The universe void currents are so great that you can't possibly imagine them. There are a trillion other entities like the world. In other words, there's also a trillion more of the sun and moon that you're seeing right now!"

Aiden was dumbfounded.

Everything that the red-headed ghost said had completely unearthed all his knowledge.

After pondering, the red-headed ghost continued, "Of course, those are only mystical legends that no one can verify. Or rather, those that can verify them are not in the world and have already ascended to the upper world."

After pausing for a moment, the red-headed ghost looked at Aiden deeply. "That red-robed woman definitely knows about these things."

Aiden remained silent.

After looking at Aiden for a long time, the red-headed ghost closed in. His eyes blazed with the flames of gossip as he asked curiously, "Little monk, what's your relationship with the woman? Why did she help you so much?"

After holding it in for five years, the red-headed ghost finally popped the question.

Aiden was stunned.

Master and disciple?

On the surface, both of them were like master and disciple. However, Aiden had never been taken in as her disciple officially.

In the depths of his heart, he did not want to acknowledge them as master and disciple either.

historical

Friends?

They couldn't be considered as that.

Benefactor?

Sort of.

That question stumped Aiden for a moment.

"Hurry and tell me! You're killing me!"

The red-headed ghost scratched his ears and cheeks impatiently.

After pondering for a long time, Aiden said slowly, "She.. she is an important friend."

The red-headed ghost shuddered with an agape mouth and his eyes widened massively.

Swoosh!

The jade-white stone in his hands dropped to the ground at the same time as his jaws.

A moment later, he gulped and the way he looked at Aiden gradually changed as he praised, "Little monk, you've really got guts.."

Aiden pointed at the jade-white stone on the ground and asked, "What does that stone has to do with the Illumination and Nether Glow that you mentioned?"

After pondering for a moment, Aiden said again, "I once obtained a secret skill from that stone, the Illumination Sword Formation."

"There's no mistake,"

The red-headed ghost nodded. "This should be the legendary Illumination Stone."

"Illumination Stone?" Aiden frowned.

The red-headed ghost replied, "There's different sayings as to where the Illumination Stone came from and how it was formed. Some people theorize that it was formed from the Extreme Dark energy of a world while others think that it's a speck of dust from Illumination."

"However, it's undeniable that the Illumination Stone is related to the Illumination. The Illumination Sword Formation that you comprehended should be a secret skill that someone comprehended using the Illumination Stone."

Aiden went deep into thought.

Indeed, when he released the Illumination Sword Formation, it was like a blazing sun and the sword energys resembled the rays of the sun as well.

The red-headed ghost continued, "The secret skill that I'm about to impart you is related to the Illumination Stone as well. In the past, the person who created this secret skill also comprehended it through the Illumination Stone.. this visual technique!"

Visual technique!

Aiden's eyes lit up.

Visual techniques were also secret techniques used to train one's eyes.

It did not matter if they were immortals, Buddhas or fiends nor did it matter if they were humans or demons.. divine formulations to train one's eyes were the rarest types of legacies!

That was because for every race, their eyes were the weakest parts of their bodies!

For tempering of flesh and blood or refinement of tendons and bones, if any issues cropped up during training, be it whether they were severely injured or their bones and tendons were snapped, everything could be recuperated to a complete recovery as long as it was adjusted in time.

However, a mistake in the training of one's eyes would lead to a huge problem – blindness!

The eyes were simply way too fragile.

For mortals, a single breeze was enough to cause them to close their eyes instinctively.

Their eyes would feel discomfort even with a grain of sand inside, let alone endure training.

The reason why visual techniques were so rare and precious were because few people would dare to risk their eyes to try and create a secret skill.

If any mishaps happened, they would go blind before their secret skills were even created.

Although the Ancient Primordial Dragon Manual was powerful, there was no legacy of a divine formulation for eye training.

The visual techniques spread in the training world had varying strengths and their directions were different as well.

The more famous ones were those such as the Bewitching Eye, Enraged Diamond Gaze and Flaming Golden Eyes.

Warriors versed in visual techniques were definitely stronger than anyone else of the same training realm in terms of combat strength!

That was because visual techniques were instantaneous and were the most difficult to defend against.
