Cultivation is just so scientific!

He himself could cultivate half-step fifth grade, but he was acutely aware that he lacked the capability; without IBMz15, without the data center space, he would not be able to refine a half-step fifth-grade corpse.

Yet here, half-step fifth-grade corpse refinings and ghost souls were created en masse.

He even began to suspect that half-step fifth grade was not the limit, for the deeper he delved, the stronger the half-step fifth-grade corpse refinings and ghost souls he encountered became.

Even within the half-step fifth grade realm, there were distinctions of strength; the disparity between the strongest half-step fifth grade and the weakest was as vast as that between the Nascent Soul Early Stage and Great Cultivators.

Nevertheless, here his gains were substantial, having obtained more half-step fifth-grade corpse refining materials than anticipated.

During this period, IBMz15 conducted an analysis and research series on the acquired half-step fifth-grade corpse refining materials.

Through calculations and deductions, a viable plan was determined: refine a fifth-grade corpse refining by utilizing thirty-six portions of half-step fifth-grade corpse refining materials.

As for advancing a half-step fifth-grade corpse refining to the fifth grade, IBMz15’s repeated calculations revealed that the advancement of half-step fifth-grade corpse refining always lacked the most crucial step.

In truth, the key point for a half-step fifth-grade corpse refining to reach the fifth grade lies in its mastery of the rules.

The challenge is that the half-step fifth-grade corpse refining, though intelligent, lacks sufficient wisdom to comprehend the rules; it can only manipulate the rules based on the comprehension from when it was alive.

Thus, despite Li Shiming inscribing billions of “Refining Corpse Rune” into these corpse refinings, it still did not directly elevate them to the fifth grade.

A half-step Great Power’s corpse could only be refined to a half-step fifth grade; advancing further proved to be exponentially more challenging than he had imagined.

This conclusion was reached after acquiring and analyzing actual half-step fifth-grade corpse refining material data via IBMz15.

This compelled Li Shiming to alter his plan; he opted to refine fifth-grade corpse refinings using Great Power corpses and fifth-grade corpses and postponed advancing half-step fifth grade refinings until he devised a feasible improvement plan.

However, the essential prerequisite remained the acquisition of more half-step fifth-grade corpse refining materials.

On the tenth day of traversing the ancient ruins, his pace had markedly slowed.

Not only were the half-step fifth-grade corpse refinings and ghost souls increasing in power, but the detrimental environmental effects upon him were also intensifying.

Now, he did not just contend with half-step fifth-grade corpse refinings and ghost souls; he also had to battle the influence of Yin Cold Energy.

If not for his cultivation in “Heavenly Human Technique,” he might have been forced to activate his defensive shield to its maximum capacity at all times just to withstand the erosion of Yin Cold Energy.

“Hmm!” As Li Shiming was walking, a sudden sensation stirred within him.

With a wave of his hand, one hundred thirty-three Holy Spirits flashed toward the left side.

The Holy Spirits, at present, emanated a sacred glow throughout their bodies, combating the Yin Cold Energy through this method.

On the other hand, the Heavenly Ghost was completely unaffected by the Yin Cold Energy, even seeming to relish the Yin Cold Energy-filled surroundings.

Here, the Yin Cold Energy already contained Rule Power, augmenting its corrosive effect by multiple factors.

The distance for Holy Spirits to perform Space Movement had been reduced to just ten meters; the prohibitions here had likewise strengthened considerably, so much so that even though Space Movement is a natural ability of Holy Spirits, it suffered a notable impact.

While performing Space Movement, the target of one Holy Spirit’s movement deviated automatically from its intended spot.

This situation suggested only one possibility: something lay hidden there, occupying the designated location.

“Indeed!” Li Shiming mused to himself.

Despite immense constraints in the ancient ruins, he could still perceive a faint trace of a special aura.

Utilizing perception here was arduous, so he resorted to the most straightforward method, having the Holy Spirits use Space Movement to tread all areas.
