"Is it within a hundred miles?"

"Hehe, that's not very wide, I'll take this as the center of the circle."

Think of it.

Ding Jian showed the wings of death, and then began to fly out in circles.

Fly, fly, fly.

An hour later.

airplanes

Suddenly, he felt the piece of Innate Overlord Knife Diagram attached to his heart tremble.

Then, it pierced through his clothes and flew out as a streamer.

"Haha"

Seeing this, Ding Jian couldn't help but be overjoyed.

At that moment, he activated the martial spirit, doubled his speed, and flew out immediately after that fragment.

Fly, fly, fly.

It had been flying for about ten miles, and suddenly saw that the streamer turned by the fragments seemed to hit an invisible wall of qi, and with a buzz, it crashed into a black hole.

All of a sudden, the fragment disappeared into the hole.

Ding Jian did not hesitate, and rushed over directly.

The next moment, he also slipped headlong into that hole.

And as soon as he entered it, the hole vanished.

The void was back to its original state.

As soon as he entered the mixed hole, Ding Jian only felt a wave of dizziness attack.

It almost knocked him unconscious.

Fortunately, after a while, everything was back to normal.

At this time, Ding Jian found himself entering an ink-like alternate dimensional space.

The heavens and the earth are dark.

The atmosphere is oppressive.

In the meantime, my heart was inexplicably flustered, and I didn't feel very comfortable.

"There is a black aura everywhere, presumably this is the so-called Black Brake Demon Domain?"

"Well, if you come, you will be safe. I'm going to wander around."

Ding Jian quickly adjusted his mentality, and then, as soon as the Grim Reaper's wings flapped, he flew out.

"Ang"

He hadn't gone far before a low dragon groan reached his ears.

"Well, is that the moan of the demon dragon?"

As soon as Ding Jian's mind moved, he sped up and flew out.

Fly, fly, fly.

When he flew about seven miles away, he spotted a huge black dragon coiling over a mountain peak.

The black dragon, covered with a layer of black and shiny scales, was a little dazzling.

Its appearance looks hideous and terrifying.

Those who are a little timid are afraid that they will be paralyzed by fright at first sight

"Suction"

"The strength is actually at the level of a half-king"

"What a terrible dragon"

Ding Jian thought about it in his heart.

call

And once the demon dragon found him, it flew directly and wanted to swallow him.

"Kill"

When Ding Jian saw it, he let out a low shout, and then drew his sword to greet him.

Soon, the two sides were fighting.

kill

kill

kill

The scene was violent and the weather was scary.

Let's say, once the sixth demon pattern is activated, it contains a demonic power to conquer the world's monsters.

That made Ding Jian like a tiger with wings, and his combat effectiveness was even more fierce.

After about a hundred rounds of fighting, when Ding Jian used a move of Heavenly Thunder into my sword, he killed the demon dragon that day.

"Whew"

"This demon dragon is really hard to deal with."

After killing that demon dragon, Ding Jian almost exhausted the true yuan power in his body.

At that moment, he hurriedly sat down and cultivated.

It took about an hour of cultivation for him to recover.

Next, he flew out again, looking for the piece of Chaos Essence Iron.

He had already determined that the piece of Chaos Essence Iron was in this Black Brake Demon Domain.

Fly, fly, fly.

After flying a few miles, he encountered another demon dragon, and another fight broke out.

This time, this demon dragon is weaker.

Therefore, it is relatively easy to kill.

After about a few dozen rounds of fighting, he managed to deal with the other party.

Not to mention, the Black Brake Demon Domain is extremely vast, almost boundless.

After Ding Jian wandered around for more than ten days, he still couldn't explore the whole picture.

And in the past ten days, he has killed twenty demon dragons before and after.

In the continuous battle, his swordsmanship became more and more proficient, and his strength improved a lot.

And every time he killed a demon dragon, when he was dying, he would ingest it into the anti-dragon space and let Ding Feiyang devour it.

"How long will it take to explore this Black Brake Demon Domain?"

Ding Jian couldn't help but sigh.

And in the next ten days, Ding Jian still persevered in the investigation.

this day.

I don't know if it's morning or afternoon.

Anyway, in this Black Brake Demon Domain, there is no sun and moon, no stars, and the environment always remains the same.

It's not clear what time it is.

Suddenly, something like Optimus Prime appeared in front of him, pitch black, with no head or tail in sight.

"That's a black pillar"

"There are countless shadows of black dragons faintly appearing on the pillar, so is it better to call it the Ten Thousand Dragons Pillar, or the Ten Thousand Demon Pillars?"

"Well, the true qi in my body is faintly fluctuating, and it seems to be longing for something, but that black pillar is the so-called Chaos Essence Iron."

"Well, let Celestial help me confirm it first."

Think of it.

He communicated with the Nine Swords Lord.

And the Nine Swords Heavenly Lord clearly told him that that black pillar was the Chaos Essence Iron.

At the same time, the Nine Swords Heavenly Lord also told him that there were thousands of demon dragon shadows wrapped around that black pillar, and ordinary people couldn't get close to it at all.

If you get closer, you will surely die.

When Ding Jian heard this, he was worried.

However, the Nine Swords Heavenly Lord then said something that made him smile.

What kind of words are you?

At that time, the Nine Swords God said to him: "Little sword, don't be discouraged, if you change to someone else, I'm afraid that you won't have a chance to collect that piece of Chaos Essence Iron, but as for you, you have a great chance." ”

When Ding Jian heard this, he was happy: "Old Jian, how can you say this?"

Nine Swords God: "Because, those dragon shadows are great evil things to others. But for those who have cultivated the Nine Shadows Soul Devouring Technique, it is a great supplement. ”

Ding Jian: "Haha, I understand, thank you for the reminder." ”

Next, after exchanging a few more words with each other.

Ding Jian accelerated and flew out excitedly.

While flying, he communicated with his stepfather Ding Feiyang.

"Father-in-law, how far have you cultivated the Nine Ghost Soul Devouring Technique now?"

"Little Sword, after devouring that ancient spirit beast form martial soul last time, it has reached the level of perfection, and after such a long period of cultivation, it is almost to the extreme. ”

"That's great. Father-in-law, there is a Ten Thousand Dragon Pillar in front of you, with countless Demon Dragon Shadows entwined on it, after you devour it, you should be able to cultivate the Nine Ghost Soul Devouring Technique to the extreme. ”

"Hehe, that's just great"

It's not a lot of work.

Ding Jian approached the Ten Thousand Dragon Pillar.

When he looked closely, he found that the fragment of the Innate Overlord Sword Tyrant was attached to the black pillar.

However, he did not rush up to collect it.
