Before he could stop Beiming's movements, the black pill was thrown out by Beiming.

Unexpectedly, this pill was not only not damaged, but rolled back with bones.

The strength used by the North Ming is not small!

"It didn't even crush like this!"

Du Wenxing suddenly became interested, stretched out his claws and picked it up, this elixir was bigger than his claws, and he needed to hold it with two hands to grasp it steadily.

What the hell is this...... Is it an elixir?

Du Wenxing's eyes showed a look of doubt, how did he look at it, what did he think, the black and round thing in front of him was more like metal!

"Don't look at it, this is a sword pill, not an elixir. Beiming's angry voice sounded, "And it's just a half-finished sword pill, it's useless at all!"

Kenmaru?

Du Wenxing was a little interested, and asked, "What is a sword pill?"

"The sword pill is the main weapon of the sword cultivation in ancient times, this thing is usually in the shape of a pill, the shape is a pill, which means a sword, it can sharpen iron like mud, and it is soft around the ring, and it is an excellent weapon. It's just that you need to control it with a unique technique, and you can't use it. What's more, this thing is still a sword pill that has not been refined, it is only a half-finished product, and it is useless at all. ”

"Oh?" Du Wenxing's eyes flickered, and he asked again, "......What is the material for refining the sword pill?"

Beiming: "Oh, that's not bad, ordinary materials can't withstand the fierce mana of sword cultivation." ”

Du Wenxing's heart moved, and the sword pill was also included in the space ring.

Just because it's useless now doesn't mean it's useless in the future.

What's wrong with the semi-finished product, there may not be no possibility of training it into success in the future!

It doesn't take up space anyway.

After receiving the sword pill, there was nothing worth noting in this Danfang.

Leave!

Du Wenxing walked into another Yongdao entrance in the Danfang.

The road is not long, only about five meters.

Soon I saw the light coming from the exit ahead.

Yo, Du Wenxing didn't dare to be careless, and stood at the entrance of the passage and looked out.

I saw that outside the Dan room, it seemed to be another world.

Vast expanses of dense fog from nowhere, tumbling and surging, obscuring everything, only a straight avenue in front of them.

"Quack, how's that, how does it feel, quack. Du Wenxing asked.

"There shouldn't be any danger. "The North Underworld Returns.

"Are you sure?" Du Wenxing looked at the scene outside the passage suspiciously.

Up and down, left and right, a fog, faintly implying a violent aura, as if as long as the slightest touch, it will attract a thunderous blow.

This should be some kind of formation, right?

After entering this cave for so long, only this formation in front of him is the best preserved, and he doesn't need to experience it personally, and with a little divine sense, his heart has already begun to flutter.

Is there really no danger?

Du Wenxing was a little bottomless in his heart.

But looking around, it seemed that there was no other way to go, so I had to set my eyes on the avenue in front of me.

On the avenue, there is a pitch-black color, and the deep black crystal floor tiles are laid out in a square circle, and the slightest attention makes people dizzy, as if the soul is about to be swallowed in.

Under these black crystal floor tiles, there are streams of black substance like liquid, and a thick evil intent escapes, through the floor tiles, constantly infiltrating the avenue.

On the top of the floor tiles, there is not nothing, on the contrary, there are countless empty figures echoing, distorted faces, terrible howls, as if there were nothing.

Wronged souls!?

Du Wenxing still couldn't help but ask again, "Quack, Beiming, are you sure there is really no danger?"

"Don't worry, these remnants are my food, just leave it to me. "The North Swears by it.

I don't know how many creatures this demon lord killed back then, and the number of remnant souls on this passage is getting more and more, and in the end it is already dense, as if it is endless, and Du Wenxing's scalp is numb.

These remnants seem to be somehow bound to this black crystal avenue, only wandering within this range, but not entering the gray mist on either side.

"Look there—" Du Wenxing said, pointing into the distance.

At the location of Du Wenxing and Beiming, as far as the eye can see, a corner of the magnificent palace looms at the end of the avenue, at the edge of the forbidden gray fog.

Such a magnificent and complete building was not discovered before entering.

It stands to reason that this looming palace is taller and more majestic than the palace that came in before, and should not be obscured.

I guess it's the effect of some kind of formation!

Du Wenxing thought to himself.

Bei Ming also saw the gorgeous hall, and said in Du Wenxing's heart: "This avenue is almost a test. ”

"Test?"

"That's right, it should be the next way of testing for the Demon Lord.

Ahead, it must be the core of the entire cave, and it is also the place where the master of the cave preaches on weekdays.

And this avenue, like the "ladder to heaven" set up by some great sects of the righteous path back then, is a test of the qualifications of disciples who listen to the Tao, as long as they can pass it within a certain period of time, they are qualified to listen to the Dao.

There are a large number of black crystal floor tiles to communicate with the demonic energy filled underground, these remnant souls can be said to be replenished, it is almost impossible to exterminate, and there is no need to extinction, as long as those demon lords can open a way out of the remnant souls in the pile. ”

"That's right. Du Wenxing nodded, and then said, "That's up to you." ”

"I'm coming, I'm coming!"

Bei Ming was not angry at all because Du Wenxing pushed the matter on his head, but was extremely excited.

The pure demonic energy in the bodies of these remnant souls is an extremely rare delicacy nowadays!

The black liquor wriggled, wrapping the toad's whole body, and then jumped to the top of the black avenue with a chirp.

Beiming stretched out tentacles one after another, looking at the large number of remnant souls wandering with light in his eyes, and before Du Wenxing could react, he had already taken care of himself.

Du Wenxing is naturally happy to see it, it is rare for this guy from Beiming to be so active, and he is just a little more relaxed.

Moreover, according to the previous discussion, the energy devoured by the Northern Underworld has its own share.

The tentacles flying in the sky plunged into the remnant souls that surged nearby, like a huge black bewitching flower blooming.

The body of the remnant soul, which was originally built from pure demonic energy, was pierced by this tentacle, but it was like some kind of terrifying plant rooted in the ordinary soil.

In particular, after these tentacles pierced into the remnant soul, they were divided into countless numbers again, as if a dense black root system spread all over the remnant soul's body, as if it was about to shatter it into tens of millions of horrors.

"Hahaha, such a pure demonic energy, it's really delicious, it's so delicious!"

With the clamor of the Northern Underworld, the black flowers composed of tentacles bloomed to the extreme, and the devouring power was also activated to the extreme, as if the endless demonic energy was extracted, and the already dark body became even darker and deeper.

The tentacles that seemed to be full of food and drink were withdrawn, like giant pythons writhing in the air.

And then, one by one, the remnant souls were extracted because of the foundation of the body, even if the demonic energy below was infinite, it was still too late to make up for it, just like the soil dismembered by the dense root system, the grass and trees were gone, the water and soil also collapsed, and they were annihilated in an instant.

Du Wenxing went all the way forward, and the North Ming devoured all the way, a big "chew".
