After Li Muran and the Thousand Illusion Fairy were ready, they separated outside the cave.

Li Muran flew in the direction of the Chaotic Stone Valley of the Dragon Field, while the Thousand Illusion Fairy took the dragon soul and flew in the opposite direction.

A few days later, Li Muran came to a dense forest near the Troubled Stone Valley, and in order not to attract the attention of those beast monks in the Troubled Stone Valley, he didn't dare to get too close. He hid in the dense forest, quietly waiting for the message from the Thousand Illusion Fairy.

At the same time, the Thousand Illusion Fairy came to a very remote and desolate place. This place is extremely far away from the dragon field, there is no teleportation circle nearby, and even the heaven and earth vitality is relatively thin, few monks come here, and high-level demonic beasts are also very rare.

"This position is almost the limit of what the two of us can use to use the Wings Double Flying Technique, so let's attract the Black Demon Dragon King here, right?" said the Thousand Illusion Fairy.

"Okay!" the dragon soul said: "It's so far away from seeing Long Ye, and it's so remote, as long as you can turn the tiger away from the mountain and lure that traitor over, you should be able to buy a lot of time to find the black dragon stone!"

Just in case, the Thousand Illusion Fairy laid layers of defensive formations nearby. Although it is impossible to really block a dragon king of the Mahayana period, as long as it can be delayed for a while, it is enough for Li Muran to perform the technique of wings and double flight, pick her and the dragon soul from here and directly teleport to Li Muran's side.

After spending a lot of time and laying out a few sets of magic circles, the Thousand Illusion Fairy said to the dragon soul: "Black Flame Daoist friends can come out!"

The dragon soul immediately turned into a demon dragon phantom and flew out of the small ding. He took a big gulp of the demonic qi around him, and said leisurely: "I haven't felt the breath of this heaven and earth for a long time! After this exposure, the traitor will know that the old decay has not yet fallen, and he will definitely do everything possible to hunt down the old decay." ”

"However, as long as you let the old decay retrieve the black dragon stone, and then hide and completely fuse it, you will be able to greatly increase your strength!

......

At the same time, far away in the largest palace of the Black Dragon Tribe, the largest tribe of the beast clan in the Dragon Clan's territory, a middle-aged monk with a burly figure and black and gold armor suddenly changed his face.

He took out a fist-sized blood-red magic bead from his arms, and the base of the magic bead was a black dragon several inches long that was entrenched. The blood-red magic bead also flashed with a flashing red light, which was quite weird.

"I actually sensed that guy's breath again!" the middle-aged monk muttered, "Strange! In that Heavenly Tribulation thousands of years ago, this king personally saw him being shattered by the Heavenly Tribulation's body of the Demon Dragon, and he had already lost his breath, why did his aura appear again?"

"Decades ago, on the Miryuno, his aura appeared for a while, but immediately disappeared again. This king rushed there to investigate carefully, but he couldn't find any clues, and thought that the inducted Yuan Soul Bead was out of the pool. And now it's happening again! Is it wrong again?"

The middle-aged monk waited quietly for a moment, and the red light emitted by the magic bead became more and more obvious, and gradually stabilized, no longer flickering. And the entrenched black dragon actually slowly opened his eyes, and the divine light in his eyes became brighter and brighter.

"There should be nothing wrong with it! it's his breath indeed!" the middle-aged monk's heart sank, and he couldn't help but recall some of the past.

"Back then, the lord of Duanmu Island calculated a hexagram for him, saying that it was too vicious, and there would be a catastrophe but he could survive in a desperate situation, is it really as his hexagram said, he has not completely fallen?"

This was the most worrying thing for the middle-aged monk for thousands of years, and when he thought of this, he felt a little uneasy.

"In any case, let's go and take a look! If he's still alive, let him die again!" said the middle-aged monk coldly.

......

The Thousand Illusion Fairy and the Dragon Soul floated quietly in the magic circle, each closing their eyes, letting go of their divine thoughts, and probing their surroundings.

Occasionally, some low-level demonic beasts flew nearby, sensing the powerful aura emitted by these two, and they all fled away in fright. This made the already extremely remote ancient times even more silent.

Suddenly, the Thousand Illusion Fairy sensed a powerful aura appearing in the distance, and she immediately opened her eyes: "Black Flame Daoist, is it the Black Evil Dragon King here?"

"Exactly!" said the dragon soul, "but his breath ......"

"Then get out of here immediately!" the Thousand Illusion Fairy then took out a transmission note, activated it, and whispered.

As soon as she had done this, that powerful aura suddenly turned into a black shadow and appeared hundreds of feet in front of them.

The black shadow turned into a burly middle-aged man covered in black and gold armor, his eyes flashed, and he stared coldly at the dragon soul beside the Thousand Illusion Fairy.

"You old fellow, you really aren't dead yet!" the middle-aged man snorted coldly, he was none other than the Black Dragon King

"The great revenge has not been avenged, how can the old decay be willing to die!" the dragon soul responded, at this time he sensed the powerful aura emanating from the black evil, and his heart was shocked:

"What's going on? With his qualifications and comprehension, being able to advance to the Mahayana stage with the help of old decay thousands of years ago is already considered the limit! How come it is that after thousands of years, he is already a mid-Mahayana monk! What kind of opportunity did he get?"

The Black Demon Dragon King glanced at the Thousand Illusion Fairy and the formation in front of her, and sneered: "This king still thinks that you have invited some kind of master to help you, but you are actually just a junior in the demon body stage! Do you think that this ordinary formation can protect your safety? With only three or two moves, this king can break it!"

As soon as the Black Demon Dragon King spoke, his body immediately changed, turning into a black-scaled demon dragon that was a hundred feet long, grabbing his claws and striking towards the formation light shield.

With two loud bangs, the first layer of the formation light shield was immediately shattered under the slap of the giant claw, and it collapsed into bits of magic light, which disappeared.

The Black Demon Dragon King spewed out a large area of raging black demonic flames with a "whew" again, rolling towards the second layer of the formation light curtain.

The power of this black demonic flame was so powerful that it directly burned the second layer of the formation light curtain completely, and it didn't even last for a breath.

"Black Dragon Flame!" The dragon soul was shocked: "The old man didn't teach you this magical power back then, how did you comprehend the old man's unique magical power?"

The Black Demon Dragon King sneered, there were only the last two layers of formation light curtains left in front of him, although these two layers of formations were slightly stronger, but with his magical means, it would only take a little more time to crack them!

"Could it be that you have already fused the old man's black dragon stone?" the dragon soul felt a chill in his heart. If it weren't for the fact that the other party had already fused his own Black Dragon Stone, I am afraid that he would not be able to comprehend his unique magical power Black Dragon Flame, and even if he could barely grasp it, it would be impossible to exert such a powerful power.

The dragon soul can't invade the opponent's body with divine thoughts, so it can't be detected. And the person in front of him does have a lot of blood connection with himself, if he fuses his own black dragon stone, there will be no rejection.

Seeing that the Black Demon Dragon King had cracked the first two layers of the formation, the Thousand Illusion Fairy couldn't help but be shocked: "The strength of this Black Demon Dragon King is much stronger than the Black Yan Daoist expected, I hope Mu Ran can cast the spell in time!"

The Thousand Illusion Fairy secretly held seven or eight spiritual fire beads in his hand, if the Black Demon Dragon King rushed in, these spiritual fire beads with strong self-explosion power could slow down the other party a little.

However, at this moment, above the head of the Thousand Illusion Fairy, a spatial vortex suddenly appeared without warning.

The power of space here was visibly distorted, and a hole the size of a zhang appeared in the void, like a bottomless vortex.

"I want to escape!" The Black Dragon King was startled, and hurriedly attacked the last two layers of magic circles with all his might, and under the continuous slapping of his claws, the light curtains of these two layers of formations were quickly shattered.

However, at this moment, a ray of light was projected from the whirlpool, enveloping the Thousand Illusion Fairy.

"Write down your life for the time being, one day the old decay will take it away!" the dragon soul snorted coldly, and also returned to the small ding in the sleeve of the Thousand Illusion Fairy.

The next moment, the glow rolled up and disappeared into the whirlpool, and although the Black Demon Dragon King had just broken the formation, he could only watch the whirlpool disappear into the void.

"What kind of strange space secret technique is this, I didn't even see her cast a spell, and I actually teleported away out of thin air! Could it be that someone else responded?" The Black Dragon King turned into a human form, his brows furrowed.

"Hmph, what about escaping! As long as you know that you are not dead, this king will chase after you relentlessly, and one day he will kill you!"

The Black Demon Dragon King was about to leave, when suddenly his mind moved: "No, he set up a formation here in advance, it seems that he expected me to be able to track his breath here. Why didn't he hide honestly and let me know that he was still alive?"

Thinking of this, the Black Evil Dragon King felt a pang in his heart, and hurriedly took out the Yuan Soul Demon Bead from his arms, and after playing a magic trick, the Demon Bead glowed with a layer of shining red light, and the black dragon entrenched at the base of the Demon Bead swam along the Demon Bead, and finally stopped on the Demon Bead, with its head facing a certain direction.

The Black Veil Dragon King thought carefully in this direction, and suddenly suddenly realized: "Oops, I actually fell for their tricks! It turns out that he deliberately lured me out so that he could find the remaining half of the black dragon stone!"

"The remaining half of the black dragon stone should be in the Troubled Stone Valley, where there are countless rocks, I have personally searched for many times, and sent a number of subordinates to search for many years, but I have not been able to find it, but after all, he is the original owner of the black dragon stone, and he can easily sense it. Just give you an hour or two, and you'll probably get it!"

"But if you want to go to the Troubled Stone Valley from here, I'm afraid it will take a few days, even if you use the Demon Dragon Escape, it will take at least half a day, and there is no time to stop it!"

Thinking of this, the Black Flame Dragon King hurriedly took out a dark golden high-level transmission note from his arms, stimulated it, and commanded in a solemn tone: "Fourth Elder, immediately lead your cronies to guard the Chaotic Stone Valley, and if you see any Terran monk or a monk pretending to be the former Black Flame Dragon King appear, you will be killed!"
