Outside the city was desolate, with the occasional sporadic dead tree, rendered as if it were purgatory in the bone-chilling wind and gray sky. In this silent environment, suddenly there was a sound of animal hooves. In the billowing smoke and dust, many figures can be vaguely discerned.

In the team, Ao Zhan took the lead, followed by the two elders Lei Tong and Lei Dian, but behind him were nearly a hundred black-clothed warriors.

"How far is it?" asked Thunderbolt in a loud voice.

Ao Zhan recalled for a moment, and then responded, "When you get to a forest, it's almost over." ”

"The Netherworld Continent is deadly and silent, but wherever there is life, it is more or less adhering to the heavenly machine, which is extraordinary!"

"According to valid information, the Tie family has already left Black Iron City one step ahead of us, we have to hurry up, we can't let them get it first. Thunderbolt roared.

Ao Zhan couldn't help frowning when he heard this, "I have injuries on my body, I can't speed up anymore, if you want to speed up, you can go first!"

"You can't go it alone, or we won't be able to keep you safe, so go ahead at this pace. With the black iron knife centipede here, the Tie family shouldn't be so easy to get it!" Lei Tong stopped and turned his head to glare at Lei Dian, who was about to get angry.

This scene was immediately captured by the keen Ao Zhan, and he sighed secretly in his heart, "These two people didn't take me seriously at all, if it weren't for the ore vein, I'm afraid this thunder would have to be shot." I don't know how Ao Jue's preparations are going......"

After rushing for a long time, the group finally arrived at the verdant ancient forest.

"It's so full of vitality, no wonder it can give birth to the essence of heaven and earth and such a powerful monster!" Lei Tong sighed with emotion.

"Don't sigh big brother, let's hurry up and enter the ore vein! Ao Zhan, where is the entrance to the ore vein?" Lei Dian seemed calm, but his eyes were shining.

"On the other side of the woods, follow me. Ao Zhan glanced at him and walked forward first.

Ao Zhan's memory is very good, but it took a lot of effort to find the entrance when he stepped on it again.

"It's a footprint, although it's covered, it's not perfectly covered!" Ao Zhan said with a frown.

"Yes, although there are no footprints, the grass in the middle has obviously been trampled on, it seems that the Tie family has already entered! Everyone be careful, beware of ambushes!" Lei Tong looked at it carefully and nodded in agreement, and at the same time glanced at Ao Zhan quite meaningfully, as if he was surprised by his keenness.

"What are you afraid of, I'll take the lead, I want to see what his Tie family means!" Lei Dian sneered and got into it first. He has his self-confidence, and he is not afraid of the iron masters and ambushes.

Seeing this, Lei Tong shook his head, smiled helplessly, and followed closely with his subordinates. Ao Zhan sneered in his heart, and secretly sighed that he didn't know whether he was alive or dead. This hole is so narrow that even if you have thousands of horses, you only need seven or eight people armed with crossbows to defend it. Lei Dian's move is indeed very inappropriate. And Lei Tong obviously saw the power of it, but he didn't stop it, which made Ao Zhan see the sloppiness and arrogance of this team.

"Brother Ao, why is it getting narrower and narrower?" After walking for a while, Lei Tong couldn't help but ask.

Lei Dian, who was in the lead, had a gloomy face at the moment, such a narrow hole, let alone dodging and moving, I am afraid that he would not even be able to retreat quickly. If someone really sets up an ambush, even if he cultivates superbly, he will definitely suffer a dark loss.

"Elder Lei Dian is the first, heroic, and not afraid of everything at all, how can I be embarrassed to say more?" Ao Zhan said sarcastically.

"Hmph!" Lei was angry, but it was not easy to attack, so he could only grit his teeth and snort coldly, and turned his head away.

"Brother Ao, don't be angry, you have penetrated into this vein, and this trip depends on you a lot. Second brother, step back quickly. Lei Tong hurriedly laughed.

"That's all I know, at least that's all I know. Ao Zhan shook his head and said.

"I don't think the Tie family will dare to be cruel to my Excellency Treasure. Lei Dian said unconvinced.

Lei Tong stopped and said loudly, "That's not necessarily, second brother, you stand back and sacrifice the shield!"

"Yes!" As Lei Tong's words fell, a man stepped forward and turned his hand to offer a crystal tortoiseshell shield, covering the entire passage for seven or eight minutes.

"Forward!" Lei Tong ordered with a wave of his hand.

Everyone in the Treasure Pavilion must have been sure in their hearts, and they began to move forward in an orderly manner. After doing this for a while, the ambush that he had scruples about never appeared.

"I said a long time ago that this Tie family wouldn't dare to be unfavorable to my Treasure Pavilion!" said Lei Dianyin and Yang angrily, and glanced at Ao Zhan.

"The low terrain ahead is coming to an end, and if there is an ambush, it must be here!" Ao Zhan said.

"Be on guard!" Lei Tong raised his hand and shouted.

The black-clothed warrior tensed his nerves, holding the tortoiseshell shield steadily, and nearly a hundred luminous stones illuminated the cave as if it were day.

"Hmm, what does it smell like?" Lei Tong stopped and told everyone to stop. At this time, there was a faint strange smell in the cave.

"It's not poisonous, it doesn't have the slightest effect on the body!" Lei Dian sniffed and said.

"Wait, listen, what's that sound?" Lei Tong shouted with a frown.

With the sudden silence, Ao Zhan gradually heard what Lei Tong said.

After only hesitating for a moment, Ao Zhan's face immediately changed, "It's the Black Iron Sword Centipede here!"

"This place is too narrow, move forward!" said Thunder.

"It's too late, second brother, that evil beast is coming! Retreat!" Lei Tong shouted.

"Damn, how could it be so coincidental?!" shouted Lei Dian as he retreated.

"It's probably caused by that strange smell!" Ao Zhan said with a little groan.

"Look!" Lei Dian roared, pointing his right hand straight behind him.

Looking at the situation, a huge centipede with a pitch-black and shiny body chased after it at great speed, and there were tattered half-cut corpses inserted in its many knife feet, and it was impossible to tell the age, but it could only be seen that it was a man who had just died, because it was still bubbling with bright red blood.

The corpse was holding a jade jade bottle in its hand, exuding a strong strange smell, exactly the same as the previous taste.

"Use one life to draw out the knife centipede, and replace us with a surprise, good plan, so ruthless!" Lei Tong squinted his eyes and was angry.

'Puff puff!'

At this moment, their retreat suddenly shot out bursts of arrows, and the Treasure Pavilion martial artists who were caught off guard died tragically more than twenty people in the first place, and they couldn't even scream.

These arrows are jet-black and extremely penetrating, as if they are specially designed to break through the gang and armor.

"Enemy attack, enemy attack!" the person who reacted immediately shouted, and at the same time sacrificed the spirit weapon to resist.

"There, ah!" As soon as someone saw where the enemy was, he was shot in the next moment.

Ao Zhan stood in front of Lei Tong and Lei Dian, but he couldn't see the situation in front of him clearly at all, and only heard the screams getting closer and closer. Behind him, the three impacts of the black iron knife had already cracked the tortoiseshell shield, and it seemed that it could not hold it anymore.

"The front and back attacks are poisonous enough!Hey, in this way, I'm afraid there won't be a few people left in the Treasure Pavilion. Ao Zhan sighed secretly.

There are a hundred martial artists in the Treasure Pavilion, among which there is also a difference between strength and weakness, and nearly half of them belong to mining experts, and they are not strong in martial arts. After these few sharp shots, most of the mining warriors who walked behind had already died.

But they could only rush desperately towards the exit, because in such a small environment, the Black Iron Sword Centipede had taken advantage of the location, and even the two elders Lei Tong and Lei Dian were invincible.

"Rush, rush me!" Lei Tong shouted.

"Rush rush!" Lei Dian was even more anxious.

With such a shout, the warriors of the Treasure Pavilion also went crazy and rushed out desperately. Ao Zhan followed closely, watching the people in front of him die one by one, splashed with blood.

'Bang!'

There was a crisp explosion behind him, Ao Zhan turned his head to look, and the tortoiseshell shield in the hand of the black-clothed warrior was shattered by the black iron knife centipede, and he himself turned into a cloud of blood mist on the spot.

"Not good!" Lei Tong and Lei Dian blurted out almost at the same time.

In the next moment, both of them were reflexive, but in the narrow hole, only Lei Dian was allowed to meet the black iron knife head-on.

The lightning flashed in Lei Dian's hand, and he slapped out a palm in a hurry, hitting the abdomen of the black iron knife centipede, making a crisp sound of hitting the metal.

"What?!" Lei Dian roared in disbelief as he pulled back.

The legs of the black iron knife turned into black light, easily cracking the stone wall, causing the stones to splash.

"Second brother!" Lei Tong exclaimed.

"I'm fine, big brother!" Lei Dian took two more steps back, and Ao Zhan saw that a large piece of flesh had been cut off from Lei Dian's right forearm, and it was dripping with blood.

"Elder is not good, the exit is blocked!" someone shouted in horror.

"What!" Lei Tong raised his eyebrows.

At this time, Lei Dian and the black iron knife dragon came to fight again, but this time the fight was not hasty, and he did not collide with it, but very skillfully avoided the black iron knife centipede's knife legs, and hit a dark energy, through its hard shell, so that its body shook fiercely, and he did not dare to step forward for a while.

"Second brother, you hold it, I'll go open the exit!" Lei Tong shouted.

"Leave it to me!" Lei Dian's confidence suddenly increased after this contact with the Black Iron Knife Centipede.

Ao Zhan didn't speak, and followed Lei Tong all the way to the entrance of the cave with difficulty. Before they could catch their breath, the two were completely dumbfounded.

Blocking the exit was a dark, shiny boulder engraved with strange runes, flickering and flickering. Even though the three Treasure Pavilion martial artists blushed, they still couldn't push the slightest.

"Get up!" Lei Tong snapped and repelled the three of them.

Purple thunder suddenly appeared on the surface of his body, gathering more and more, making a muffled thunder cracking sound, rendering his whole person like a thunder god.

"Open!" Lei Tong burst out with both palms, and his voice became extremely low, as if a spring thunder had exploded in his stomach.

With this palm, Ao Zhan immediately changed color, and sighed secretly, "With such power, if it hits me, you will definitely die!"

'Bang!'

However, after a loud bang, even though the whole cave shook, the strange boulder still did not move.

"What! how can this be?" At this moment, even Lei Tong was not calm.

"Ahh

There was a scream behind him, and it was thunderous.

'Boom, boom!'

There was another bang behind him, the sound was getting closer and closer, and the dust in the cave was getting louder and louder. Lei Dian staggered back, with multiple deep visible bone wounds around his body, and a cut on the left side of his face that extended to his chin.

"Second brother, what's going on?!" Lei Tong shouted.

"Big brother, this beast is actually clumsy! Its intelligence is not low, and it is by no means comparable to ordinary underworld beasts! What's the matter, why hasn't the cave been opened yet?" Lei Dian said in a sigh of resentment.

"This stone is strange, I'm afraid that the two of us won't be able to open it together...... Lei Tong shook his head helplessly, looking at it, there are only half of a hundred warriors left at the moment, and the corpses are all over the ground, and the blood is thick.

"Ao Zhan, what are you doing?" Lei Zhan was silent, but suddenly found that Ao Zhan was sitting cross-legged on the ground, exuding a layer of hazy red light around him, quietly refining the blood all over the ground in the cave.

"Anyway, they're all dead, so instead of wasting it in vain, it's better to refine some flesh and blood power for me and find a better chance of life. Ao Zhan replied indifferently.

Originally, he had some scruples and was reluctant to refine and ingest these essence blood, but there were too many people who died, and all of them were blood-filled martial artists, and these essence blood was enough for him to break through the first order, so he knew that it would anger everyone, but he still did it without hesitation.
