Chapter 205: 148 Big Hanging Case Small Hanging (4100)_1 Chapter 205: 148 Big Hanging Case Small Hanging (4100)_1 Meanwhile, a symbol appeared underneath the entry.

The symbol was made of densely packed faint red patterns.

Casio’s gaze shifted slightly, and he understood the symbol’s meaning.

“Upgrading limit in progress…

There is still room for the Stone Armor Skill to improve…

Lack of Disaster Essence…

Upgrade failed…”

Casio quickly grasped the meaning of the system’s response. The spiritual blood produced by the Wisdom Rune could be used to elevate the limit of one’s abilities, for instance, it could raise the two-layered Hard Qigong Stone Armor Skill to three layers. Of course, a prerequisite was that the ability being improved still had room for development.

The failure of the final elevation was quite normal since he only obtained a tiny bit of Disaster Essence. If merely killing a member of Alpha’s Direct Bloodline could elevate an ability, Casio would have already established an unbeatable foundation.

Every technique could be elevated to its limit, thus clearing the path. He only needed to cultivate in an orderly manner and follow the path.

Casio sighed softly and shifted his gaze.

“Huh? Why is there a plus sign on Elephant Soul Secret Technique?”

He raised his eyebrows in surprise and refocused his attention.

“Elephant Soul Secret Technique: Insect Bite 66.7%+ (Three layers in total)”

This time, the plus sign appeared not within the skill layers but within the skill progress. Casio attempted to add a point again.

The entry of Elephant Soul Secret Technique immediately became blurry.

A light blue pattern symbol appeared below.

“Breaking through the bottleneck in progress…

Yet to reach the bottleneck…

Lack of Disaster Essence…

Breaking through failed…”

Well, it could be used to break through a bottleneck?! Casio’s eyes widened as he immediately started to further explore the system.

After a while, Casio discovered another function.

In the top right view, the entries for Wind Elephant Secret Martial Art and Stone Armor Skill were simultaneously blurred and flickered, showing signs of merging.

A pale yellow symbol appeared at the bottom.

“Skill fusion in progress…

Both skills are in conflict, hence poorly matched…

Lack of Disaster Essence…

Fusion failed…”

Casio immediately decided to retract his previous statement; “What’s the point of this thing, it’s annoying to even look at.” In contrast, the Wisdom Rune was incredibly useful.

Although it couldn’t directly enhance Casio’s strength, its other auxiliary abilities were undoubtedly game-changing.

First, it could raise the limit of a technique.

Second, it could inspire breakthroughs.

Third, it could fuse highly compatible techniques.

As of now, these were the three aspects that Casio had figured out. Their abilities were indeed related to the Wisdom Rune and Spiritual Blood.

He wondered if there were any hidden features to be found.

Of course, the Wisdom Rune did have limitations.

After obtaining the first strand of Disaster Essence, Casio reinterpreted the information of the Wisdom Rune and got more feedback. In ancient myths, everything cycles unceasingly, like a constantly rotating Ouroboros. And the time taken for the entire world to complete one cycle is one year, which is when Ouroboros circles back to its original position.

That is to say, after the Wisdom Rune produces Spiritual Blood once, it will enter a long cooling period of one year.

In other words, Casio can only use the Wisdom Rune once a year. After storing up enough Disaster Essence, he can choose any one from the three functions, after which the rune will lapse into silence.

His fiery excitement slightly subsided, as he calmed down. Indeed, the Wisdom Rune, being a product of a mysterious civilization, likely wouldn’t have incredibly powerful abilities without a cost.

The only thing capable of that would be the Retrospective Ability.

The Retrospective Ability that Casio possessed was incredibly unruly, even able to directly manifest a real era from history. Everything he cultivated there, he could bring back to the real world.

This was clearly unmatched by the Wisdom Rune for the time being.

“Wait a moment…”

Casio suddenly realized something. He immediately had a question: Which has a higher priority, the Retrospective Ability or Wisdom Rune?

It should be the Retrospective Ability, Casio tended to believe.

Then the question arose, does the world of different retrospective eras count as one world? And what about the original real world?

“In ancient myths, everything cycles unceasingly, like a constantly rotating Ouroboros. And the time taken for the entire world to complete one cycle is one year, Ouroboros circles back to its original position.”

Theoretically, a person resides in only one world, and time is continuous. But what if someone resides in more than one world? With time being haphazard and disjointed?

Would that cause a bug? Continuously refreshing?

For example, Casio is currently in the “Bronze Ring World fifty years ago.” He has used up the Wisdom Rune’s one elevation opportunity. If he immediately returns to the “Real World”, will the Wisdom Rune refresh instantly? And if Casio then enters the “Wind Elephant Ivory Pendant World seventy years ago”, will the Wisdom Rune refresh again?

This seems to be a bit out of line with the rules and principles.

But in fact, it should be reasonable, if the Retrospective Ability has a higher priority than the Wisdom Rune. The lower level surrenders to the higher level, the Wisdom Rune surrenders to the Retrospective Ability. And the Retrospective Ability is an unruly game-changer; it does not follow the rules and principles.

It should be this way… this needs further verification through experiments.

Upon thinking this far, Casio suddenly realized that he seemed to have exploited two bugs. Once with the Shadow Demon, and the other time with the Wisdom Rune, if successful. Both exploits were based on the Retrospective Ability, for which Casio was very grateful.
