The headless zombie still walked a short distance before falling to the ground with a "poof", and finally turned into a pile of ashes in the flames.

Only then did Lu Xu raise his hand at the pile of ashes.

With a "whoosh", a black array flag flew out of it and landed firmly in his hand.

He just looked down at the array flag in his hand a few times, and then flew back with a move.

"Fellow Daoist, it's this array flag, with this array of flags...... "As soon as the short man in black waited for Lu Xu's feet to land, he immediately stepped forward to explain a few words.

But as soon as Lu Xu waved his hand, he directly interrupted the words behind him, and threw the array flag in his hand towards him, and said expressionlessly:

"Don't talk nonsense, open the circle immediately, I warn you, if you dare to play any conspiracy, be careful of your life. ”

"Yes, if you don't dare to do it, your life will be in the hands of Daoyou, and you will never dare to have any other thoughts, and you will immediately cast a spell to open the seal. The short man in black grabbed the black array flag in his hand, looked at it carefully, and then recalled the method of opening the seal that the tall man in black told him, and hurriedly agreed.

Then he immediately walked to the center of the hall, raised the aura high with one hand, pinched the trick with one hand, and punched a few tricks at the formation flag, and began to chant words in his mouth.

The incantation sound is obscure, but it has an indescribable sense of rhythm.

With a "poof", the seemingly ordinary black array flag suddenly burst into brilliance, and became brighter and brighter, and finally broke away from the one-handed control of the short black-clothed man with a tremble, and shot towards the air above the hall.

The black array flag continued to hover in the middle of the hall, and then it spun around, shooting out several black rays of light.

The next moment, countless black runes appeared above the hall, and the black runes kept flickering, and then they spun around the array flag. After a few breaths, all the black runes began to rain downwards and disappeared into the ground.

Then there was a rumbling sound from the ground, and the entire hall began to tremble slightly, and another huge black array emerged from the ground, but the black light turned, and a terrifying forbidden aura rolled out.

Immediately, the concussion in the hall grew stronger, as if something was about to emerge from the ground.

At the same time, the ground in the center of the black array suddenly cracked as if it were torn, and a large black hole appeared out of thin air, and there was a faint sound of ghosts crying wolves howling from inside.

"This is the entrance to the seal?" Lu Xu said as he looked at the big black hole torn in the ground out of thin air, and a trace of fiery flashed in his eyes.

"This should be the place as my companion said, and there can be no mistake. The short man in black looked at the big hole and said with a hint of excitement on his face.

"Oh, since you're so sure, then you go down first. Lu Xu glanced at the short man in black and said lightly.

"Daoist friends want to go down first?" the short man in black said hesitantly when he heard this.

"Why, don't you dare? Or do you have something unspeakable?" Lu Xu said with an eyebrow.

"No, no...... In the lower first down, in the lower this down. The short man in black seemed to know that he had no possibility of opposing at all, and replied with a smile on his face.

Then he took a deep breath, cautiously approached the black hole on the ground, and after a probe looked inside, he gritted his teeth and jumped into it.

After a short while, Lu Xu didn't hear any unusual noise, and then secretly deducted the earth turtle shield in his hand, and flew into the black hole in the same flash.

The black hole was not too deep, and Lu Xu felt that he was just a few breaths, and he came to another hall with a light in his eyes.

But except for a small area controlled by the magic circle at the foothold, the rest of the place was all covered with thick black gas, making it impossible to see the appearance inside clearly.

And the short man in black stayed honestly in the center of the circle.

"Hey, this is corpse qi!" Lu Xu swept away the thick black qi outside the magic circle, and said with a frown.

"That's right, and it's a very strong corpse qi, there must be a powerful corpse refining corpse here, otherwise it would be impossible to have such a strong corpse qi. Could it be ......" The short man in black looked at the black qi around him, and replied with some hesitation.

"Oh, you mean that Jindan stage refining corpse? Hearing this, Lu Xu replied with a sneer.

"Hehe, down there, down here for this corpse. When the short man in black heard this, he couldn't help but have a look of condescension on his face.

But at this moment, the black qi that seemed to be static around him suddenly rolled and surged, and began to gather rapidly in the same direction.

In a matter of moments, the black qi that had originally filled the entire hall all shrank and gathered in a place not far from them, forming a huge black air mass.

In the black air mass, there was a huge copper coffin standing upright, and the lid of the copper coffin had been opened at some point, and there was a person lying on it.

Or to be more precise, it was not a person lying inside, but a corpse.

The corpse had a hideous face, with pointed green hairs all over its body, its eyes closed, and two hideous fangs showing at the corners of its mouth, as if it was sleeping.

And the black air mass only rotated in a few breaths, and then it was completely submerged into the corpse's body.

Lu Xu couldn't help but gasp when he saw such a strange situation.

But before he could react, the short man in black, who had been honest beside him, suddenly jumped out of his side without the slightest warning, and rushed towards the bronze coffin excitedly, shouting excitedly at the same time;

"The green-haired iron corpse, it turned out to be the green-haired iron corpse, and it was really here, great, great. ”

The short man in black moved extremely quickly, and after a few jumps, he had already run a few feet away from the bronze coffin.

Seeing this, Lu Xu's face sank.

But at this moment, the short man in black who was still excited suddenly let out a miserable scream, only to see a thin palm piercing out of his chest, pinching a slightly beating bright red heart between his five fingers.

"How can this be, you...... You should be in a deep sleep...... How could it be possible to wake up. The short man in black could barely believe his eyes, and looked in horror at the green-haired iron corpse in front of him who had opened his eyes at some point.

The one who pierced his heart was the green-haired iron corpse lying in the bronze coffin.

The five fingers of the green-haired iron corpse suddenly closed, and the heart of the short man in black was crushed and shattered, and then his arm jerked suddenly, and the short man in black was lifted by the waist, and then he bowed his head, bit his neck, and sucked blood wildly.

Seeing this, Lu Xu's face changed even more, and he suddenly withdrew the shadowless needle in the short black-clothed human body with one move, and then his body moved, and he flew towards the entrance that came in.

"Bang".

As soon as he approached the entrance, a black light curtain suddenly appeared in front of him, and he bounced it back unprepared.

"Don't waste your efforts, this sealing circle is allowed to enter but not to leave, you want to break the seal in the circle, at least a stick of incense time, do you think I will give you this time. The green-haired iron corpse finally took the blood-dripping mouth away from the corpse, revealing two huge fangs, and said lightly to Lu Xu.

"Are you?" Lu Xu said slowly with a gloomy face, could it be that the other party was really the Jindan period monk of Haotian Sect, then it would be troublesome.

At the same time, Lu Xu swept the three spiral knives in front of him with one hand, and after a slight shake of the sleeve in the other hand, the moon blade flew out of it and began to slowly rotate around his body.

The Void Ape also suddenly had golden hair standing upside down, his eyes flashing with golden light, and he jumped onto Lu Xu's shoulder with a flicker.

"Green-haired iron corpse! Well, this body should be considered a green-haired iron corpse. When I was approaching the end of my life, I had to break the cauldron and do the method of putting death and revitalizing. Haha, I didn't expect that the sky would never stop me, and it really made me practice, hahahaha!" The green-haired iron corpse suddenly laughed wildly when he heard this.

Then the green-haired iron corpse's arm was raised, and a finger was pointed at Lu Xu's side of the void.

"Poof".

A flame came in front of Lu Xu, and it came so fast that he didn't even have time to think about it.

He just subconsciously turned his head suddenly, and the flames flashed tightly in his ears, hitting the stone wall not far behind.

A deep hole as thick as a finger immediately appeared, and at the same time, a large area of the stone wall was burned by the flames and turned into white ash, scattered on the ground. And on the top of the stone wall, a shocking hole was formed.

"Spiritual fire!"

After Lu Xu witnessed this scene, his face immediately changed greatly.

The green-haired iron corpse in the huge bronze coffin suddenly popped out several fingers with a hehe.

The sound of "snort" was loud, and several flames flashed and hit all parts of Lu Xu's body at the same time.

But Lu Xu, who was already prepared, how could he still stay where he was, without thinking, his body suddenly shook, and he appeared a few feet away with a series of afterimages.

Several flames flashed again, causing a few more holes in the stone wall behind them, and then the stone walls that were hit by the flames turned into ashes one after another, and they were cut off more than a zhang thick.

"No, this is not a spiritual fire! the power of a real spiritual fire will not only be to this extent!" Lu Xu looked back and quickly glanced at the stone wall that had been thinned by a layer, and then swept away the flames burning on the arm of the green-haired iron corpse, and immediately said with a narrowed eye.

"Hehe, I am a Jindan stage monk myself, and I have devoured the spiritual fire, you are just a foundation building stage monk, do you still want to escape from my hands and ascend to heaven. This place has been completely banned, and you are destined to be sucked dry of your blood by me. The green-haired iron corpse said with a heaval voice.

Then he bent his five fingers, and the flame in his hand turned into a thin wire of fire, shooting towards Lu Xu.
