Chapter 204 - 204 Ding Your external device has arrived (4100)_2

Chapter 204: Ding! Your external device has arrived (4100)_2 Chapter 204: Ding! Your external device has arrived (4100)_2 Cold sweat covered his back densely.

He didn’t know what he was afraid of, but an inexplicable fear crawled over him, causing goosebumps to rise all over his body.

Casio slapped his aching head, the fragmented information he had previously seen quickly blurred, like a dream.

He stood in place, dazed for half a minute, before realizing that the amber-colored pool water had completely disappeared. He was standing on the empty surface of the pool, the carved mouth on the wall in front of him had vanished, replaced by a smooth, cold, black wall.

He tried bouncing and found the suction at the bottom of the pool was completely gone.

Casio immediately jumped up and clawed at the edge of the pool.

With a flip, he stood on the hall floor. He glanced down and saw the hall’s surface filled with incomprehensible lines and symbols. However, it appeared to have been destroyed, with large blank areas and lines that abruptly ended halfway.

“Huh?”

Casio noticed a palm-sized black Ouroboros symbol burnt into his chest. The snake’s eye and scales were masterfully depicted, reflecting a black-purple light from different angles.

“What is this?”

He reached out a hand to touch it, finding nothing abnormal.

Casio lifted his head and suddenly focused on the top right corner.

An Ouroboros symbol was hanging prominently: ∞.

He paused, then tried focusing on the Ouroboros symbol as he used to. Immediately, a flood of chaotic information surged into Casio’s mind, making him sway slightly.

The symbol was known as Ouroboros, the blood chalice that brewed the blood of longevity. It was also a wisdom rune guiding the climb forward.

Ouroboros came from the mysterious Oyon civilization. It was said to be one of the infinite and endlessly distant five keystones.

Then followed a pile of cryptic and tongue-twisting words.

In the end, the icing on the cake was one sentence.

Draw from the essence of disasters, brew the blood of the spirit.

So…

What is the essence of disasters? And what is the blood of spirit?

Is this some kind of riddle?

Casio could guess a bit about the blood of spirit – it should be something beneficial. As for the essence of disasters, he was utterly clueless. Was it the Obsession Energy needed for retrospective ability? The two didn’t seem to be the same thing; the difference was somewhat big…

While Casio was pondering, he seemed to hear that vague voice encouraging him to live again. The shadow in the fog, what was it plotting? Guiding him to this relic and bestowing an unknown wisdom rune.

Although it seemed like a good thing, Casio hated the feeling of being manipulated and controlled by others.

It made him feel like a dangerous pawn.

Casio was somewhat worried inside, but quickly brushed off the emotion. After all, he was in the Era of Retrospection.

This was a historical scene from fifty years ago!

Even if there were any schemes or cunning tricks, they would all be ineffective the moment Casio returned to the real world.

Even if he died in the Era of Retrospection, it wouldn’t matter.

At most, it would be considered a failed retrospection, one that didn’t bring back any strength.

This time, Casio’s retrospection was not time-bound. He even reserved enough Obsession Energy for a subsequent retrospection.

The dangers of the Shadow Demon in the future were within manageable limits.

Theoretically, Casio didn’t need to have any other concerns.

“Forget it, I’ll worry about it after I get out.”

He decided on the next goal. This relic was filled with dangerous white beetles running rampant. It wasn’t the best time to explore.

Casio did not want to collide with those beetles again. He took a deep breath, found an exit and quickly entered it.

Half a day later, in the middle of a cave. Casio sat on the ground to rest, a bottle and a piece of worn parchment in front of him. He never expected to acquire the secret medicine that he had stumbled upon at dusk. After dodging many traps he also obtained a parchment from the same stone chamber.

The language on it was incomprehensible, but it seemed to be related to the secret medicine.

Casio was delighted to find these two items, as it meant he wasn’t far from the cave exit. But the greater the hope, the greater the disappointment. Casio still found himself going in circles in the passageway.

It was like a labyrinth with endless twists and turns. No one could tell where they were, or how far they were from the exit. In such situations, the only option was to keep trying.

Fortunately, Casio was already a master of fist techniques, capable of living without food and sleeping rough for half a month without danger.

He still had plenty of time.

Several days passed, and Casio stood at a crossroad, hesitating. He was on the verge of developing decision paralysis; the environment and passages were the same, without any change.

The path ahead could be a trap, or it could be fraught with monsters.

All along the way, both Casio’s spirit and physical body had somewhat exhausted, and his appearance had visibly become haggard. Especially because the ruins were dangerous, he would wake up immediately at even the smallest rustle of wind, which irritated him even more.

He exhaled a breath and looked at the upper right corner.

The Wisdom Rune remained unchanged without any feedback. It just hung there, unnecessarily taking up a slot.

What’s the use of this thing? It’s annoying just to look at it.

With no outlet for his frustration, Casio slowly stretched out his hand and made a hand knife to carve a cross mark on the wall. This somewhat helped him navigate the ruins.

That was better than doing nothing at all.

Suddenly, he paused his drawing finger. He held his breath and listened intently. A few seconds later, Casio pressed his right cheek against the wall.

His brow furrowed, and his eyes seemed to light up gradually.

Dense blood-red light instantly covered his entire pupil.

Bang!

The rock exploded, and the wall shook violently.

A full-strength Iron Fist, like a pile driver, punched through the hard wall and thrust out like a black python.

His fingers caught an ellipse-shaped object and pulled it in.

The head of a Blood Clan youth got stuck in the hole, his eyes continuously rolling back in his head, looking like his neck was about to be snapped off.

“Excellent!”

Casio laughed loudly and punched the youth’s head back in.

The rock-white muscles then swelled up, and his huge figure like a wild cow, charged fiercely at the wall.

Boom! The dust fell like rain, and he ended up in another parallel passage. Three surprised Blood Clan youths were beside him.

Finally… finally… I’ve taken a big detour…

A relieved look appeared on Casio’s face, and the corners of his mouth drew a slight smile involuntarily. Seeing his indifferent look and his companions on the ground, the three Blood Clan youths roared and charged at him, their figures swelling and distorting.

They all turned into red and black bat monsters.

Casio clenching his itchy fist. He didn’t know whether it was due to being cooped up for so long, but he found the ugly Blood Clan in their blood-filled state oddly endearing now.

So endearing that it made one want to shatter their bones inch by inch with a fist, to sever those strong muscle fibres with a hand knife, and those three round heads look so much like fragile watermelons…

Casio yearned to vent out the violent killing desire in his heart.

This time, it had nothing to do with the Shadow Demon. It should…

Wham! Wham! Wham!

The wall let out three muffled noises. Several Blood Clan heads were brutally pressed against the wall by the Iron Hand, leaving blood-soaked depressions and cracks. One of them was even directly killed by Casio’s immense force.

“Awesome…”

Shaking off the blood on his hand, Casio twisted his neck, making a continuous cracking sound. He was about to pick up the two still alive Blood Clan members when he suddenly noticed a change in the Wisdom Rune at the upper right corner. It was no longer stagnant!

On the right side of the Ouroboros shaped Rune, a blank progress bar appeared. It was long and thin. On close observation, there was a tiny bit of blood-red color at the end of the bar, suggesting a slight progression.

“So, does Disaster Essence have something to do with dark creatures?!”

Casio immediately made connections.

Blinking his eyes, he noticed more changes.

“Stone Armor Skill: Major Accomplisment (Two layers +)”

A barely visible plus sign had appeared after “Two layers,” which sent a thrill through Casio’s heart and left his mind reeling.

“Ding, your cheat has arrived…”

Dismissing the hallucinatory sound in his ears, Casio felt a little parched in his throat.

A moment later, Casio tried to focus his attention on the plus sign. In an instant, the entire phrase of the Stone Armor Skill became blurred.
