In the dim and damp cave, Ao Zhan sat in the calf-deep sewage, his eyes closed, and a faint red light emanating from his body.

He has been cultivating since he was a child, and the exercises he practices are very strange, relying on constantly refining his own essence and blood to improve his cultivation, and while he can rely on his essence blood to perform various spells, he can also control the blood in others' bodies to a certain extent.

It was precisely because of this method that he was able to conquer the three small tribes of Chiyan, Xuanyou, and Bi Yao when he was only eight years old, and refine three drops of precious blood.

An hour later, Ao Zhan slowly opened his eyes.

"The aura of the Netherworld Continent is far less domineering than the aura of my Ao Xia Continent, and there is very little resistance to cultivation, with the strength of my physical body, I can arbitrarily absorb and break through in a very short period of time, but the premise is that there is enough aura. Obviously, the aura in this place is limited......" Ao Zhan muttered to himself in a low voice.

He was a little helpless, and the thin aura in the cave made it impossible for him to continue to improve his skills. At this moment, there was only a very small drop of blood suspended in his dantian, less than one percent of his previous cultivation.

"It seems that the only way to move on is to move on. Ao Zhan got up helplessly.

......

On the other side, Tie Lan and his party couldn't help but feel a little anxious when they saw that an hour had passed.

"Damn it, you're not going to die, are you?" said the Iron Barbarian with a frown.

"Don't worry, let me try. Tie Lan stopped and took out the purple Heavenly Witch Drum.

'Bang bang bang ......!'

The Heavenly Witch Drum sounded in a strange rhythm, and at the same time, it emitted circles of purple ripples visible to the naked eye.

"Ahh

Ao Zhan, who was slowly moving forward, suddenly changed his face, covered his chest with a clench, couldn't stop crying in pain, and his seven orifices were bleeding.

Tie Lan and the others, who were standing in front of the entrance of the cave, immediately heard the faint shouts of Ao Zhan.

"Hehe, this kid is really greasy!Sister Lan, shake it hard, let him survive and not die!"

"He's not dead now, and he seems to be lucky, and I think this third entrance is the right way to the vein. Tie Lan was very happy.

"Sister Lan, it's not completely certain yet, I think it's better to send someone to take a look, maybe the journey was safe the previous hour. The other girl was more cautious.

"Feng'er has a point, Tie Shan, you go in and have a look. The Iron Barbarian pointed to a man behind him.

"Me?" the man's face changed.

"Why, don't you want to go?" said the Iron Barbarian, his eyes shining.

The man named Tieshan trembled, gritted his teeth and stopped talking, and plunged into the cave. At this time, the Heavenly Witch Drum in Tie Lan's hand was still shaking.

"Ahhh However, his madness provokes the real danger of this hole.

A pitch-black centipede ten meters long!

This centipede has no eyes, the carapace behind it is like black metal, and the thin legs are like a steel knife, and it can easily cut through the stone wall during its movements, and it is extremely sharp.

Ao Zhan was taken aback, forcibly held back the pain, covered his mouth and plunged into the shallow water. The huge centipede hung upside down on the rock wall, and after listening quietly for a while, it determined the direction of Ao Zhan and was ready to pounce.

Ao Zhan's heart was raised in his throat. Just when he was at a loss, there was a wading sound from inside the cave. The black centipede immediately fell silent and hung silently above the stone cave.

Ao Zhan also found that the pain in his body suddenly disappeared at this time, which undoubtedly won him a glimmer of life.

Tie Shan carried the war knife and walked over with a relaxed expression. He remembered the words of Tie Lan and them, and remembered that the journey of an hour was safe.

But he miscalculated Ao Zhan's travel speed, and it took him less than half an hour to come to the location where Ao Zhan was, under the black centipede.

"Iron Barbarian, I'll go to your uncle! Let Lao Tzu be a pathfinding stone, you fucking remember it for me!" Tie Shan scolded all the way, completely unaware of the danger above his head.

At this moment, the black centipede suddenly attacked. The whole body leaned down halfway, and dozens of thin legs like knives stirred, with bursts of piercing face.

"Huh?!"

Tie Shan smelled a gust of fishy wind and immediately retreated, but even so, his right hand holding the war knife was still stirred up by the dozens of thin legs of the black centipede.

Holding the war knife in his hand, he flew straight to Ao Zhan's side who was hiding under the water. Taking advantage of the loud noise, Ao Zhan dragged his war knife and ran, quickly moving away from the terrifying centipede.

Behind him, Iron Mountain's heart-rending screams kept coming. He had no pity for the Iron Family, just reminded himself that he couldn't stop.

At the entrance of the cave, Tie Shan's screams made Tie Lan and the others turn pale.

Finally, the shouting stopped.

"Why is that kid okay after entering, and Tie Shan died less than half an hour after entering?" Iron Barbarian said in a deep voice.

"I don't know, but it's certain that this road is not safe!" Tie Lan shook her head.

"Sister Lan, let's see if that kid is still alive!" Tie Feng'er hurriedly said.

"I don't think he's still alive......" Tie Lan shook her head, but she still shook the Heavenly Witch Drum.

The strange rhythm sounded again, and Ao Zhan, who was exhausted, immediately shouted heartbreakingly. But in just a moment, he forcibly gritted his teeth and held back, covering his mouth fiercely.

He knew very well that if he alarmed the black centipede, it would only be a dead end!

Because Ao Zhan had walked far away at the moment, and he only screamed, Tie Lan and the others did not hear any sound.

There was no sound, and he died. Tie Lan said with a cold face, and then put away the Heavenly Witch Drum.

"No, Sister Lan, listen, is there a voice?" Tie Feng'er suddenly frowned and listened attentively.

"What's the sound?" the Iron Barbarian listened with his ear pressed to the stone wall.

The voice is getting closer...... The voice seems to be ...... Ah, it's not good, it's a monster!" Tie Lanhua lost her face and snorted.

The Tie family, who had been distracted by this roar, suddenly found that a huge black centipede had come out of the hole, with half a rotten head stuck in one of its legs, and something was chewing in its mouth.

Everyone in the Tie family was pale, and they almost wanted to vomit.

"Black, black iron knife centipede!" Tie Lan also lost his face.

"Run, we're no match for it!" Tie Feng'er shouted.

"Escape to the third passage!" shouted Tielan.

The Tie family reacted immediately. When they came, the road was relatively low, and they could not let everyone run freely, but the low-flat black iron knife could run very fast, which was very bad for them. But the cave that the black iron knife crisscrossed out of was open, which not only made it easy to escape, but also allowed them to get closer to their destination.

After Tie Lan let out a loud roar, before the black iron knife could react, he rushed in first, accompanied by Tie Barbarian and Tie Feng'er. The rest of the Iron Family warriors, six of them were dismantled in an instant.

The black iron sword dragon flew around and rushed into the third cave at great speed, continuing to chase and kill the iron warrior.

Tie Lan and the others were exhausted, and they thought that Ao Zhan was dead, so they never used the Heavenly Witch Drum again. Ao Zhan, who was not tortured, let go of his speed and ran until he reached the end of a section of the cave.

The cave is much more open and filled with an amazing aura.

"The aura in this place is more than ten times more than ten times more than the aura in the previous passage! If I can cultivate here, in less than two years, I will be able to return to my previous realm!" Ao Zhan's eyes flickered, but he knew that he didn't have that much time.

He sighed and looked at the gray stone on the ground.

"Strange, why do I feel the aura on this stone?" Ao Zhan wondered.

He picked up a piece and squeezed it hard. With a 'snap', the gray stone burst, and several streams of gray energy visible to the naked eye fluttered up and slowly disappeared into the air.

"It's aura, very pure aura! It turns out that this is the Netherstone Mine in the mouth of the Tie family!" Ao Zhan suddenly understood, and his eyes lit up.

Nowadays, what he lacks most is energy!

"One more question......" Ao Zhan calmed down and frowned.

After entering the passage, he will suddenly feel a heart-rending pain all over his body for no reason. He had doubted the cave, thinking that the pain that had happened to him was an unknown danger. But when he found out that Iron Mountain was not like this, he began to ponder.

"Tie Lan is so relieved that I came in, I'm afraid it's probably her ghost, that slut. Ao Zhan's face sank like water, "After hearing the man's screams, they must have thought that I was also dead, so they didn't make any more bad ...... That said, now I don't have to worry about it for the time being, I have to improve my strength quickly. ”

After having a plan in his heart, Ao Zhan completely calmed down. He picked up the Nether Stones around him and began to absorb the aura from them.

Since there were no spirit stones in the Ao Xia Continent, he would not absorb them. However, his method is also more direct, which is to pinch and explode, and quickly absorb the aura as it drifts away, but this causes nearly half of the waste.

Ao Zhan's dantian is like a dry desert, and the whale sucks up the spiritual power like water and transforms it into pure energy.

The blood droplets in his dantian continued to grow, and in just two hours, they were already the size of a thumb.

Speaking of which, he was able to absorb energy so desperately, relying on stronger meridians and more pioneering dantian than before. If the others were as crazy as him, I'm afraid they would have exploded and died.

"Time, time, I'm still the most short of time!" Ao Zhan sighed helplessly. He heard the sound of hurried wading, and immediately understood that he was afraid that the Tie family had arrived.

"I didn't expect them to survive. Ao Zhan's eyes had adapted to the dark environment, and he saw Tie Lan and the others who were running wildly from a distance.

He quietly picked up his sword, hid in a corner, and clearly spilled several Nether Stones on the ground.

Looking at Tie Lan up close again, Ao Zhan's heart couldn't help but feel a touch of happiness. Tie Lan and Tie Feng'er's clothes were in tatters, leaking large patches of snow white, and there were obvious blood marks. And the remaining nine Iron Family warriors were either seriously injured or had their hands and fingers broken. Obviously, it was not easy to be tossed by the black iron knife centipede.

"It's unlucky, it's actually an adult black iron knife centipede!" the iron barbarian said angrily.

"The Hu family concealed the facts, this is their revenge! It turns out that half of their people last time were not killed by us at all! It's ridiculous, we thought it was like a divine help......" Tie Lan's face became colder and colder.

"Sister Lan, are you saying that after our sneak attack last time, those Hu family members who were forced into the stone cave were not killed by the Gu poison of the Heavenly Witch Drum, but because of the Black Iron Knife Centipede?" the iron barbarian's eyes widened.

Tie Lan didn't speak.

"I felt a little strange at the time, but at that time we were all immersed in joy and didn't think about it......" Tie Feng'er said with a pale face.

"Sister Lan, look!" suddenly shouted an Iron Family martial artist with a broken index finger on his right hand.

"What's wrong?" Tie Lan's nerves, which had just relaxed, immediately tensed again.

"It's the Nether Stone, there's the Nether Stone on the ground!" the Iron Barbarian roared, his eyes lit up.

"Be quiet, don't bring that monster here!" Tie Lan scolded, took a piece and observed it carefully, and after a moment she was surprised, "It's a medium-grade Nether Stone." It's still scattered on the surface, and this vein is definitely more precious than we guessed before!"

"Sister Lan, the stone walls are full of nether stones, God, this piece is of the highest grade!"

"I found a piece too!"

"I have one here!"

"Quick, fill as much as you can for me!" Tie Lan said excitedly. She had a delicate bracelet inlaid with three emerald gemstones, and in an instant, some digging tools appeared in her hand and threw them to the Iron Barbarian and the others.

Tie Lan and Tie Feng'er lost their female images, like an old man, they threw off their arms and dug, constantly collecting the Netherstone Stone.

Ao Zhan, who was hiding in the dead corner, found out that the entire wall cave was covered with netherworld stones. It's a pity that he can only watch and dare not make any movements.

"Haha, there are more Nether Stones here!" An Iron Family martial artist was in a very good mood, and he came to Ao Zhan's location excitedly.

He squatted down and picked it up, until he reached Ao Zhan's feet.

"Hey, what is this?" he stared at Ao Zhan's leather boots, ready to touch them.

"This is your talisman!" Ao Zhan suddenly spoke, and the sword in his hand stabbed out, condescendingly piercing the man's heart.

"Ahhh

"What's going on!" Tie Lan and the others exclaimed.

Ao Zhan didn't stop, and rushed out with a 'swish', making a 'pop' sound of treading water. As soon as this sound entered their ears, Tie Lan and the others immediately picked up torches and shone them over.

"It's him!" Tie Feng'er said in disbelief.

"He's not dead!" Tie Lan couldn't accept it.

"He killed Shanzi, chase me!" the Iron Barbarian was furious.

"He can't run. Tie Lan shook her head contemptuously, flipped her hand and took out the Heavenly Witch Drum.

'Bang bang bang!'

The strange rhythm sounded again, and this time the distance also made Ao Zhan suffer the most violent torture of the Heavenly Witch Drum Poison.

"Sure enough, it's you slut!" Ao Zhan fell into the dirty water, his face flushed, and he tried to hold back this sentence.
