Chapter 351: Spiritual Bone and Yin Qi

These giant skeletons stood motionless, their bodies crystal-clear like white jade, but the aura they emitted had reached the late-stage Qi Refinement level.

Wang Yu muttered in his mouth, the banner in his hand grew in the wind, turned into a zhang-high size again, and with a 'boom', was inserted directly into the ground.

Then he formed a seal with one hand and pointed at the bone banner.

With a 'whoosh' sound.

A gust of grey hazy Yin wind blew out from the banner, sweeping across the bone piles around.

The crystal-clear white bones in the bone piles instantly bounced up, sticking to these giant skeletons one after another, and dissolved and deformed.

Grey light flickered on the surface of the giant skeletons, and soon thick bone armor with thorns condensed, and at the same time, various bone weapons appeared in their hands, some with giant bows a zhang high, some with bone shields half a meter thick, and some with giant blades nearly two zhang long.

The aura on these giant skeletons also rose by a large margin, reaching the late-stage Qi Refinement level.

"Go!"

Just at this moment, Wang Yu formed a seal and pointed at the bone banner.

With a 'puff' sound.

The pitch-black banner surface fluttered, and a white bone gate pattern appeared hazily on the banner surface.

The next moment, all the giant skeletons' bodies trembled, turned into balls of grey Qi, flew into the sky, and threw themselves into the giant bone gate one after another.

Only to see that on the pitch-black banner surface, there were instantly more giant skeleton patterns in the bone gate, looking like they were rushing out from the gate.

At the same time, grey-white inscription phantoms also appeared on the banner surface, overlapping, as many as twenty-five.

This banner had actually completed the fusion of the White Bone Human Demon and the Yin Soul Banner, and had already reached the second-rank mid-grade level.

The reason why such a demon path artifact would appear in the login hall was naturally because the second-rank spiritual bones of the second-rank wind-fire bone blade that Wang Yu had personally refined could be copied in this space.

With an unlimited amount of second-rank spiritual bone materials, it was naturally not a difficult task for him to refine high-quality White Bone Human Demons and Yin Soul Banners here.

As for the Yin Qi needed for the two to be nourished, it was essentially just a mutation of heaven and earth spiritual Qi. As long as one used these second-rank spiritual bones to arrange a simple prohibition of fierce baleful wind and water, the Yin Qi contained within could be converted bit by bit.

Of course, the higher the rank of the spiritual bones used for this conversion, the better. Using the effect of a whole demon beast skeleton was also better.

This small means of converting Yin Qi was not only used in large quantities by demon path disciples, but there were also many records in the classics of the Great Ming Four Sects, and many secret technique methods also required Yin Qi.

Although the Yin Qi converted by this method was limited, and wanting to maintain it at a certain level required consuming quite a few spiritual bones every day, and it could not be compared with the Yin lands and Yin pools of those demon path sects, it was enough for him to nourish his own artifacts.

After all, the spiritual bones he could copy in the login hall were unlimited, making the Yin Qi endless, unlike those demon path Yin pools and Yin lands, which required constant investment of Yin-natured materials to maintain, and at the same time had to supply the common consumption of dozens to hundreds of disciples.

These demon path disciples wanted to enter these Yin pools and Yin lands, and also needed to pay contribution points and spiritual stones; it was not something they could use just because they wanted to.

Of course, besides these means, demon path cultivators also often liked to use one-time slaughter to obtain the Yin Qi needed for cultivation.

This method could also obtain quite a lot of pure Yin Qi at one time by directly refining the remnant souls of living beings.

Wang Yu naturally would not adopt this method, and could only use the method of converting spiritual bones to slowly accumulate Yin Qi.

The White Bone Human Demon and the Yin Soul Banner he nourished in his real cave dwelling were still a bit short of fusing into the White Bone Yin Demon Banner, also because of the lack of Yin Qi.

The Yin Qi converted by first-rank spiritual bones was far worse than second-rank spiritual bones in both quantity and purity, causing the quality of the White Bone Human Demon and the Yin Soul Banner nourished in the cave dwelling to always be a bit short.

On the contrary, the White Bone Human Demon and the Yin Soul Banner in the login hall, because they directly used second-rank materials, satisfied the requirements for fusion as soon as they were refined.

After he fused them directly, he obtained the second-rank low-grade White Bone Yin Demon Banner, and with an unlimited supply of Yin Qi, he even nourished this artifact from the fifteen-inscription level to the mid-grade twenty-five-inscription level in just a few short years.

But even so, in the real world, the spiritual stones he had spent on purchasing spiritual bones over these years had already reached an astonishing figure, and the cultivation of the Chiyang Great Art was an even bottomless pit, making the spiritual stones and contribution points on his body almost completely empty.

Even if it weren't for the fact that he had quietly become a second-rank alchemist two years ago and sold a batch of unused second-rank pills at a nearby market, he would have long been worried about spiritual stones.

As for the contribution points exchanged by first-rank artifacts over these years, they were far from enough to make up for the gap, and he even owed eighty or ninety thousand contribution points at the General Affairs Hall using his status as a true disciple.

Not long ago, Wang Yu had also made up his mind to find a good opportunity to show the sect his ability to refine second-rank artifacts.

After all, he had been constantly practicing in the login hall over these years and could already easily refine more than a dozen types of second-rank artifacts.

Among these second-rank artifacts, he almost had no possibility of failure for low-grade artifacts below twenty-four inscriptions, and he had a seventy or eighty percent success rate for two or three types of mid-grade artifacts.

For the high-grade artifact with fifty-two inscriptions that he practiced the most, he only had a thirty percent chance of refining it at one time.

It seems that whether it is improving artifact refining or alchemy ability, there is only one way: practice makes perfect.

But Wang Yu did not expect that before he had time to do this, he would first encounter the major event of the demon path formally invading.

This made him somewhat hesitant about whether he should still reveal his second-rank artifact refining ability.

Wang Yu thought about this matter, feeling his head swell a bit. After taking a deep breath, he still focused his attention on the second-rank mid-grade White Bone Yin Demon Banner in front of him.

He looked at the rolling black mist of Yin Qi nearby, and looked up at the high place again.

Only to see that ten-plus zhang high in the sky, there was also rolling black Qi and gusts of Yin wind.

Wang Yu then patted the giant banner in front of him with one hand, injecting pure magic power into it.

The grey-white inscription phantoms on the banner surface turned simultaneously, gathering in the same place, and the previously disappeared bone gate phantom appeared on the banner surface again.

"Whoosh!"

The bone gate phantom trembled slightly, and a stream of grey light filaments sprayed in all directions.

Wherever the light filaments passed, the mist transformed by Yin Qi was swept away, rushing toward Wang Yu's location like a tide, and all of them sank into the giant bone gate phantom.

In just a few breaths, all the black mist was sucked clean by the giant bone gate.

Without the obstruction of the black mist, a semi-circular, inverted, semi-transparent light shield covering an area of one mu appeared in the surrounding void.

Outside the light shield, the familiar silver hall could be vaguely seen.

After the giant bone banner sucked in so much pure Yin Qi, the pitch-black banner surface glowed with a layer of faint light, but after Wang Yu formed a seal with one hand, it disappeared together with the giant bone gate phantom.

Beckoning again, the giant banner shot into the sky and was inserted back onto the bone altar like a black light.

Wang Yu looked at the void that had become empty, his expression unchanged, stepped on the ground with his toes, muttered in his mouth, and injected a burst of magic power under his feet.

The next moment, four black array disks slowly emerged from the ground at the four corners inside the light shield, followed by streams of grey light columns spraying out from them, shooting into the sky.

"Woo-woo!"

Under each bone pile, large patches of grey light array phantoms appeared, and strange sounds came from them.

Streams of thick black Qi emerged from the bone piles in large quantities, sinking into the void, and the bone piles also flew rapidly to become shorter at a speed visible to the naked eye.

Until these bone piles were nearly half smaller, Wang Yu sensed the Yin Qi contained in the void with his divine sense, and then stepped on the ground with his toes again.

"Puff!" "Puff!"

The light columns and the patches of grey light arrays all dissipated instantly, and those black array disks sank into the ground again and disappeared without a trace.

Inside the light shield, it became filled with black Qi again, but the purity of the Yin Qi was less than one-third of what it was before.

After all, this means of stimulating the power of the prohibition to accelerate the conversion of Yin Qi at one time consumed more spiritual bones. Under normal circumstances, no cultivator would do such a thing of killing the goose that lays the golden eggs.

It was only in the login hall that Wang Yu did not care about this bit of spiritual bone consumption, so he would activate the prohibition once every time he logged in to accelerate the nourishment progress of this White Bone Yin Demon Banner.

Wang Yu was really curious, in the login hall, to what level could this second-rank artifact be cultivated in one breath?

Is it second-rank high-grade, or top-grade?

Or could it break through to the third-rank artifact level?

During this process, besides being able to obtain some experience in nourishing artifacts and avoiding making mistakes in the real world, another reason was that this White Bone Yin Demon Banner was somewhat special, and had a big difference from other artifacts he refined here.

Wang Yu thought of this, grabbed into the void with both hands, and crystal light flashed in his palms, and each object began to be condensed out of thin air.

One was a white bone blade, with cyan-red glow curling on the surface; it was exactly that wind-fire bone blade.

The other was a miniature banner a foot long, with a bone pole and a black banner surface; it was exactly the White Bone Yin Demon Banner!

But the former quickly became clearly visible and was finally condensed out, while the latter remained blurry and shaking, and with a 'bang', it dissipated and disappeared. ===== CHAPTER 352 =====
