Chapter 471

Wang Yu stared at the banner in his hand, his thoughts turning rapidly, and suddenly remembering something, he flicked his wrist.

A whistling sound immediately came from the pitch-black banner surface, and gusts of black Qi sprayed out from it.

In the rolling black Qi, three one-horned ghost creatures, over a zhang tall with green fangs, emerged.

These were precisely the first-rank yin ghosts transformed after the yin spirits advanced.

These ghosts were, of course, not the first batch of yin ghosts born from this banner.

Those entry-rank yin ghosts born by devouring living souls while in the Blue Star World had long since been devoured by the more powerful living souls born later.

These yin ghosts were newly born after Wang Yu returned to the Cultivation World and reopened the seal on the yin energy within the banner, allowing the yin spirits to devour each other.

But he had only been back in the Cultivation World for a little over two months, and as for placing the Yin Soul Banner in the yin energy land to nourish it, that was only a matter of the last half-month; how could yin ghosts be born so quickly?

Furthermore, he had not yet put living soul iron into the banner's space.

Could it be that this second-rank Yin Soul Banner had the special effect of accelerating the birth of entry-rank ghost creatures?

Wang Yu looked at the three yin ghosts in front of him, then glanced at the bone banner in his hand, and fell into deep thought.

He could roughly guess the reason for the Yin Soul Banner advancing to a second-rank magic artifact; it was mostly related to the batch of entry-rank ghost creatures born when this magic artifact was in the Blue Star World.

After all, according to the advancement method of the Yin Soul Banner, there was already a path that relied on the banner's natal ghost creatures advancing, which in turn promoted the advancement of the banner body itself.

Although yin ghosts were only first-rank ghost creatures and only a few were born in Blue Star at the time, more than a dozen entry-rank domestic pig souls were born in one go later on.

Since these entry-rank living souls devoured yin ghosts and a large number of yin spirits in the banner space, they could barely be considered the banner's natal ghost creatures.

It was not too strange that so many entry-rank ghost creatures were born in this Yin Soul Banner at once, which in turn forcibly pushed the bone banner to the second-rank level.

It should have been because there was no spiritual energy in the Blue Star World that it forcibly suppressed this Yin Soul Banner from advancing on its own; now that it had returned to the Cultivation World and replenished a large amount of yin energy, it had suddenly born several magic artifact inscriptions and advanced on its own.

With Wang Yu's status as a second-rank artifact refiner, he quickly figured out what was going on, and while suddenly enlightened, he was overjoyed.

The Yin Soul Banner was already a second-rank magic artifact; if it were synthesized into a White Bone Yin Demon Banner now, wouldn't it be highly likely to become a second-rank mid-grade magic artifact or higher?

No, he couldn't use first-rank white bone human demons to fuse with the second-rank Yin Soul Banner now, otherwise it would be too much of a pity.

If he could make these white bone human demons also advance to the second-rank level by forcibly devouring ghost creatures, and then fuse them into a White Bone Yin Demon Banner, wouldn't it be highly likely to reach the second-rank top-grade level?

He knew that the best second-rank magic artifact in his hand, the Mishan Seal, was only a mid-grade magic artifact with thirty-six inscriptions, but it was enough to make most Foundation Establishment cultivators envious.

After all, many Foundation Establishment cultivators spent their whole lives with only one or two second-rank low-grade magic artifacts, and mid-grade magic artifacts were already the ultimate goal most Foundation Establishment cultivators could hope for.

Think of Miao Feng of the Heisha Sect; the two magic artifacts he used were only low-grade, and this was already the wealth he had accumulated over many years after becoming the master of a small force.

However, the thirteen white bone human demons were currently only at the late Qi Refinement level; to advance to the second rank, besides nourishing them with a large amount of second-rank animal bones, he feared the only way was to devour a large number of ghost creatures.

After all, white bone human demons were inherently half-puppet, half-ghost existences, and could also increase their own strength by devouring other ghost creatures.

He happened to have a large pile of living soul iron brought back from the Blue Star World; it seemed highly likely that he could cultivate these thirteen white bone human demons to the second-rank level.

Thinking of this, Wang Yu made a decision. He pointed at his brow with one hand, and with a roll of silver light, a large pile of pitch-black iron blocks appeared directly in front of the thirteen white bone human demons.

Then, he pinched spell techniques with both hands, and his ten fingers flicked out white spell techniques, beginning to add sealing spells of varying strengths to these living soul irons, so that each piece of living soul iron would be unsealed only after a period of time, allowing living souls to appear continuously.

Just as Wang Yu finished adding the spells, from the top piece of living soul iron, rooster soul phantoms, not large in size and emitting blood light, began to fly out.

The thirteen white bone skeletons that had been sitting cross-legged without moving all stood up and directly raised their large hands to grab at these rooster soul phantoms.

In the underground cultivation room.

Wang Yu was toying with a small black leather bag in his hand, even attempting to infuse a wisp of mana into it.

"Puff," a sound.

Fifteen silver inscription phantoms appeared on the surface of the black leather bag. As the bag mouth opened, it sprayed out a gust of black wind, which circled and danced around his body.

In the black wind, dots of crystalline light flickered vaguely; they were actually sparse black sand grains, but they looked exceptionally scarce.

"Interesting."

Wang Yu murmured, an expression of interest appearing on his face.

With his level as a second-rank artifact refiner, he could see at a glance that although this leather bag was only a low-grade magic artifact, it was a very rare type of composite magic artifact.

Whether it was the leather bag or the black sand grains inside, they were actually separate magic artifacts, but after being used together, the power was significantly increased, and it could also be regarded as a second-rank magic artifact.

Most of the original black sand grains had been directly destroyed by the fierce fire of the Fire Flame Blade during his battle, so the remaining few sand grains naturally could not be said to have much power.

But both the leather bag and the sand grain refining techniques had their own unique features, which were quite beneficial for improving his artifact refining arts.

Thinking of this, Wang Yu shook the leather bag in his hand, and the black wind and sand rolled back into the bag.

After flipping his palm, the leather bag disappeared without a trace.

At this moment, Wang Yu silently recited "Login Interface," and with a roll of white light before his eyes, he appeared on the metal chair in the center of the white hall.

He looked at the giant screen in front of him and said faintly:

"Taiyuan, activate the deduction function."

As soon as the words fell, the giant screen in front of him lit up, and a golden mechanical funnel pattern emerged. At the same time, the system's dull mechanical voice sounded in the hall:

"Blue Star Huaguo citizen Ding Yu, Blue Star Alliance special reserve, member of the interstellar tactical mecha squad, number GLX, special authorization level none, possesses temporary deduction authority, remaining times 3, deduction authorization passed..."

"Taiyuan, deduce a second-rank natal magic artifact blueprint; the deduction direction is to maximize the power of the Red Sun Great Art, the inscriptions used should be primarily based on the Fire Flame Blade, the materials used should be primarily second-rank Refined Flame Copper, and the magic artifact type should be primarily attack-oriented, with defense as secondary." Wang Yu's voice was clear.

Since he had already verified that returning to Blue Star to reset the system once could restore the deduction authority three times, he used it once without hesitation at this moment.

He was already at the third level of Foundation Establishment; naturally, he could no longer be without the most important protective treasure, a natal magic artifact.
