Secondary metal materials have great utility for the current Ye Nan.

At this moment, after refining all the remaining array weapon fragments in his body, the injuries on his body had recovered as much as seventy or eighty percent.

The little bit of flesh grew unusually fast, and the blood in its body had begun to glow a faint golden color, as if it were a metal solution.

Ye Nan wiped the blood stains on his body slightly, and then looked at the corner of the space.

In this corner, the souls of Ying Chang and others have been included in it.

Ying Chang and the others were strong, and their soul bodies were extremely condensed, almost comparable to Yin Souls.

Ye Nan's soul power was released at this moment, and the soul threads wrapped these souls in the blink of an eye.

After advancing to the second stage of soul devouring, Ye Nan's soul power did not increase significantly, but its degree of condensation was several times stronger than before.

At this moment, in just a quarter of an hour, the souls of Ying Chang and the others were completely refined.

"The soul power of an ordinary spirit pattern master is a whole, and it cannot be separated, even if you use your soul power to control a weapon, you can only control one thing. And my soul has become inextricably linked, and when it is strong enough, it can control several weapons at the same time!"

Ye Nan's eyes burned, he knew that the inextricable benefits were not limited to this.

If Ye Nan was able to cultivate the soul attack technique in the future, then these countless soul threads could even use several techniques together without affecting each other.

After pondering for a moment at this moment, Ye Nan took out the inky black ball again.

This ball can release the killing space, and the horror in it has already been experienced by Ye Nan.

Several cracks appeared on the orb again. The four spirit patterns on it were also much darker.

"This inky black orb is a damaged artifact. Only by absorbing metal energy can it show its power. And the blood in my body has metallic energy. I don't know if it will work on this ball!"

Ye Nan carefully looked at the jet-black ball, and then bit his finger and dotted it on the ball.

Traces of blood continued to seep down the fingertips into the ball, and Ye Nan's soul power spread out, sensing it finely.

There are still countless bubbles inside the sphere, and each bubble is like an independent space. When Ye Nan's blood seeped into it, it was quickly absorbed by one of the bubbles.

"It worked!"

Ye Nan sensed this scene, and his face was slightly happy.

Swish!

That's when it happened. Ye Nan's soul power was suddenly bounced out, and then he saw a light curtain rushing out from above the inky black ball, reflecting in the air.

"It's ......"

Ye Nan's eyes narrowed, and he stared at the light curtain in mid-air.

This light curtain is pitch black, and there are circular spaces on it, and there are hundreds of them.

At the moment, most of the many circular spaces were dim, and only two were somewhat anomalous.

One of them was extremely bright, while the other flashed scarlet, and the light of the Dao jumped endlessly.

"Could it be that these hundreds of circular spaces are all killing spaces!"

Ye Nan thought of a possibility, and his heart was shocked.

He saw that the brightly lit space should be the one that had been activated. And in that space, there was a scarlet swirling bubble in a sphere that was probably absorbing its own blood.

"Hundreds of killing spaces, if this sphere is complete. Then how terrifying its power will be!"

Ye Nan was a little undaring to imagine at the moment, every killing space could definitely wipe out a star powerhouse, and if hundreds of them joined forces in one place, the terrifying scene made his scalp a little numb when he thought about it.

"Strange! There are obviously only four spirit patterns on this ball, which means that when it is complete, it is only a low-grade treasure weapon, how can it have so much space for killing!"

Ye Nan immediately frowned, a little puzzled, and immediately took the ball in front of him and looked at it carefully.

"Huh?"

Suddenly, Ye Nan actually found two faint traces from below the four spirit patterns above the ball.

However, the traces were already in tatters, and they could not be integrated into one piece.

"It's actually two hidden spirit patterns, no wonder!"

Ye Nan suddenly realized at this moment that when this round ball was complete, it was not a low-grade treasure, but a high-grade treasure with six spirit patterns, but the two hidden spirit patterns on it were completely damaged.

"Treasures can only be refined by spirit pattern masters, and this high-grade treasure weapon, the person refining it must be a high-level spirit pattern master!"

Ye Nan secretly said in his heart that it was a pity, although there were only two hidden spirit patterns damaged on this high-grade treasure, its value was no longer one in a hundred, and now this round ball was equivalent to the defective product in the lower-grade treasure.

"Most of the space above this light curtain is useless, but it should still be able to excite a few more, and raise the quality of this ball to the rank of low-grade treasures!"

Ye Nan's eyes sparkled, and then he looked at the circular space full of scarlet.

Ye Nan's finger was still on the ball, and the blood was constantly absorbed by the bubbles in the ball.

An Hour......

Two Hours......

......

Time passed slowly, and when four hours passed quietly, the second killing space was still not stimulated.

Ye Nan's expression was a little sluggish, the blood in his body was now absorbed too much by the bubble, but it was no longer enough to support it.

Seeing that the second space showed no signs of being stimulated, Ye Nan could only sigh lightly and detach his fingers from the ball.

"It seems that it is not so simple to stimulate this second space!"

Ye Nan could only hope to find some spiritual weapons for this second killing space to absorb metal energy.

After thinking about it, Ye Nan put away the ink-black ball, and then his figure flashed and walked out of the internal space.

The soul power was dispersed, and Ye Nan's soul silk could already pass through the inky black stone gate and sense the scene outside the cave hall.

At this moment, the warriors in the corridor outside had already left cleanly, and he was the only one left in the entire cave.

Ye Nan didn't leave there, and then stared at the demonic energy in the cave hall thoughtfully.

This demonic qi was cold and cold, and there was a faint trace of decay in it, as if it had existed for countless years.

"There are no demons or monsters here, how can there be so much demonic energy!"

Ye Nan was very puzzled. The footsteps are moving slightly. Walk slowly through the cave hall.

The size of the cave hall is thousands of feet. The interior is extremely empty, and the patterns on the surrounding stone walls are also mottled and cannot be seen clearly.

The floor of the cave hall is paved with black stone slabs, and its material is the same as that of the stone door, which also has the effect of isolating soul power.

Da Da Da ......

The sound of Ye Nan's footsteps was extremely clear, and he kept walking, as if he wanted to find the source of this demonic energy.

Boom......

At this moment, when Ye Nan's footsteps stepped on the ground again. He stopped for a moment.

"There's something weird about this slate!"

The sound of Ye Nan's footsteps before was extremely solid, and it was obvious that the ground was below. And this black stone slab actually made a hollow sound, obviously there was another mystery underneath.

Although he found something strange, Ye Nan did not rush to open it, but took the lead in sitting cross-legged on the ground, and the flame in his palm flashed, and began to compress the flame beads.

The scene below is still unknown, whether there is a demon in it, Ye Nan is not sure, he can only prepare for the worst now.

With the Soul Eater advancing to the second stage. Ye Nan now compressed the flame orb with great ease. At this moment, it only took half a day to compress as many as 100 pieces.

Protected by numerous flame orbs. Ye Nan took out the ink-black ball again, and slightly touched it, and the killing space flashed.

It was only at this time that Ye Nannan grabbed the gap in the stone slab with his palm and opened it.

Call!!!

At the moment when Ye Nan lifted the stone slab, the billowing cold demonic qi rushed from below, which was extremely terrifying.

"That's amazing!"

This demonic qi was already so thick that it was eroding the human body, and Ye Nan quickly took a few steps back and dodged away.

"With such a strong demonic aura, what is underneath?"

Ye Nan was very puzzled, it was not the first time he had seen such a strong demonic qi. At the bottom of the Netherworld Pool in the Demon Valley, where many demonic old men sealed by spirit patterns were located, the intensity of the demonic qi was comparable to that of this place.

"Could it be that this place is also a place of seals?"

Ye Nan's eyes flickered, but he was a little hesitant whether to go down.

The demon old man he had encountered in the Netherworld Pool before could be said to be the most powerful existence that Ye Nan had encountered, and he was as weak as an ant in front of him.

And at this moment, if this kind of monster is also sealed below, Ye Nan is afraid that he will not have such good luck.

Snort!

Just when Ye Nan hesitated, he saw a flash of transparent energy on his body, which transformed into a transparent light mask to protect his body in the blink of an eye.

"This ......"

Ye Nan was surprised in his heart, this transparent energy was nothing else, but the energy that poured into his body when he just entered the Broken Blade Cliff, and it was also the basis for him to control many demon beasts here.

After this energy entered his body, he stayed quietly in the dantian, but he didn't want to move at this moment.

Ye Nan stretched out his palm towards the place where the demonic qi was, but found that this energy light shield could completely resist the demonic qi and prevent it from eroding his body in the slightest.

"Curious!"

Ye Nan's eyes flashed slightly, and he made a decision in his heart at the moment, and his body jumped into this cave in a single stroke.

The demonic qi in the cave was tumbling, and its intensity was already enough to isolate soul thoughts, and Ye Nan could only detect two feet away from his body.

"Destined person, you're finally here......"

At this moment, a deep voice of vicissitudes resounded, making Ye Nan's body stunned.

A ghostly light flashed in his eyes, and his pupils came out.

At this moment, the rolling demonic qi around his body could no longer stop Ye Nan's sight, and his eyes looked at the front of the cave.

I saw that on the stone wall in front of me, the inky black chains were vertical and horizontal, locking an old and withered figure to it.

The figure's hair was gray and gray, its head drooping, and its entire body seemed to have begun to deform and twist.

"Who are you?" Ye Nan stood quietly in place, but his heart was already full of energy.

"Destined person, the old man has finally waited for you......"

As the old voice resounded again, the figure's head slowly lifted, and its gray hair fluttered on both sides, revealing its face.

Seeing this countenance, Ye Nan's body shook violently, and he only felt pain like a knife in his heart.

"Grandpa Lin......" (To be continued......)
