In the dim stone cave, the jumping flames illuminated the coldness on the faces of Tie Lan and the others.

"Boy, you're looking for death!" the Iron Barbarian smirked.

"What did you do to me?" Ao Zhan stared at the Heavenly Witch Drum in Tie Lan's hand, knowing that the problem was with her.

"It's just a poisonous Gu. Tie Lan said indifferently, "I'm looking away, let's say, who are you?

"Hey, you don't pee like you are now, and you deserve to threaten me?" Ao Zhan looked hideous.

Tie Lan sneered and sneered, "No matter what it is, it's not like you, a bedbug. Oh, you're not even a bed bug, just a humble ant!"

"Hahaha, I'll let you know who the real ants are!" Ao Zhan went crazy and slammed his fists into the hole in the wall.

'Bang bang bang!'

Ao Zhan went berserk, slamming desperately, ignoring the bloody fists, and making a lot of movement.

"Hah, are you fool hurting yourself?" the Iron Barbarian laughed.

"You're stupid! He's luring the Black Iron Knife Centipede over!Stop, stop him!" Iron Lan yelled angrily.

At this moment, there was a rustling sound in the cave, and all the people who had encountered the black iron knife dragon immediately changed color, and understood that the monster was already very close.

"Hey, hey, hey, if you're not afraid of death, just shake it slowly!" Ao Zhan yelled and left.

"Damn!" Tie Lan was furious, but she could only choose to flee for her life in the face of the black iron knife that was about to arrive.

Ao Zhan and the Tie family ran one after the other, followed by the extremely fast black iron knife centipede.

"Help me, save me!ah......h

The black iron sword dragon tore apart the one-armed iron warrior who was left behind, and the sword of this warrior could not pierce the carapace of the black iron sword dragon at all.

The Tie family was so tired and worried about their own safety that no one turned back, let alone came back to save him.

In a short distance, six of the remaining eleven Tie family members died, leaving only Tie Lan, Tie Feng'er, Tie Manzi and the other two.

Ao Zhan ran wildly all the way and took the lead to the end of this section of the passage. In this relatively large cave, there is a small hole that can only be leaned over to continue walking, and it can be seen from the passage that the stone wall is very thick and solid.

"You can only take one step at a time. After muttering to himself, Ao Zhan climbed in.

The rock wall has a metallic feel like iron to the touch, revealing a cold chill. The light at the entrance of the cave in front of Ao Zhan made Ao Zhan look forward to it.

"It's been going down, how can there be light?" Ao Zhan couldn't help but have some doubts in his heart as he advanced.

Half an hour later, he crawled out of the narrow hole and came to a strange place.

It's a beehive-like space, filled with regular grottoes that can accommodate one person to stand, and there are estimated to be hundreds of them. Ao Zhan felt it carefully, and there was a wind blowing out of it. In the middle of this space, there are huge Nether Stones densely embedded, these Nether Stones are round and full, and the inside is actually glowing.

"The Nether Stone here is of a higher grade. Ao Zhan just sighed, and then put his mind on those holes again. In his opinion, if he can't get out, no amount of Netherstone will be useless.

"It's windy, which means that these holes are connected to the outside world!" Ao Zhan's eyes lit up. "It's a pity that I don't have a bracelet like Tie Lan, and I can't take much Netherstone ......"

"There's light ahead, hurry up!" Tie Lan's shout came from inside the cave.

"It's okay, this stone wall is very hard, and that beast can't get in!" Tie Feng'er said lightly.

Ao Zhan's face turned cold, "It's really ghostly, I have to quickly dispose of the poisonous Gu on my body, otherwise I will be subject to her everywhere!"

Breaking dozens of Netherstone stones, Ao Zhan drilled into a windless grotto, and walked hundreds of meters inside before stopping.

He concentrated and meditated, pulling the blood droplets and essence blood in the dantian, carefully searching for every part of his body. But after a few weeks, he didn't notice anything unusual.

"I perceive it with my own essence and blood, if there is Gu poison in my body, it is impossible not to find it. Now there is only one possibility, and that is...... Gu poison is in my blood!" Ao Zhan's expression became even more relaxed.

His exercises are to constantly refine the blood of the body, which is used to promote the growth of the physical body and cultivation. In addition, his alchemy can not only refine the blood of others, but also his own. Therefore, it only takes a little more effort for him to get rid of the toxins in his blood.

With the help of the pure energy of the Nether Stone, he constantly tempered the blood around his body. Later, he even forced a part of his blood out of his body, suspended it in front of him, and slowly tempered it.

"Boy, get out of here! I'm going to scrape you alive!" the Iron Barbarian's voice echoed.

"Don't shout, he's not stupid, how can he come out?" Tie Lan was in a bad mood, the casualties this time were too great.

"This guy is decisive and ruthless, and he is by no means a good stubble. Hu family, when did there be such a number one person?" Tie Feng'er frowned, as if caught in a memory.

"Sister Lan, look, it's the ultimate Nether Stone!" the remaining two Iron Family martial artists shouted at the same time.

"As I expected, there is a superb Nether Stone in this Netherstone vein. Don't worry about that kid, mine first, anyway, the black iron knife can't get in for the time being. Tie Lan gave the order.

"It's a pity that there are only five of us left, and we can't mine much. The Iron Barbarian sighed.

"This vein has been discovered by us, you can collect as much as you can this time, and wait for the next time the family master comes to remove the black iron knife centipede, this vein is my Tie family!" Tie Lan said nonchalantly.

Tie Feng'er and the others all laughed when they heard this, they all had storage bracelets, and they were already able to make a lot of money this time. Wait for the next time the family master comes, the black iron knife is not a threat.

"My Tie family is destined to rise, and I can already see the future of Black Iron City for the next hundred years!" Tie Lan became excited.

As time passed, the five Tielan had filled their storage bracelets to the brim. They sat contentedly cross-legged, eating dried meat and other dry foods.

On the other side, Ao Zhan's eyes were closed and his face was pale. A large cloud of scarlet blood floated in front of him, wriggling like a demon, and a stream of bloody gas filled the entire grotto.

Three drops of purple-black blood were squeezed out, and when they dripped down, they were burned out by an invisible fire. The blood became more and more bright red, and the wriggling became more and more violent. Ao Zhan's hands kept moving, pinching and blasting the Nether Stone one after another, using the pure and powerful spiritual power in it to maintain the consumption of one-third of the blood out of the body.

Twenty-eight Nether Stones were exhausted, and this time his blood refining was also over. The Gu poison of the Heavenly Witch Drum was all eliminated, and his whole person was relaxed.

"Although the Gu poison has been lifted, I can't have a head-on conflict with the Tie family now. Let's walk along this grotto first and see if we can get out. Ao Zhan made a decision.

Although he was unwilling, he couldn't help it, now one of the caves with the most Nether Stones has been occupied by the Iron Family, and although his strength has improved, it is impossible for him to confront them head-on.

This way was a long walk, and when the cave was open again, Ao Zhan was stunned.

He was back in the grotto, the hive-like space!

"Why did you come back again?" Ao Zhan was taken aback.

At this time, in the middle of this space, the five members of the Tie family, who were eating and drinking, raised their heads when they heard this.

"Damn it, it's you!" the iron brute threw away the jerky in his hand, and his eyes seemed to be about to burst into flames.

"Kill!" The remaining two Iron Family warriors immediately jumped up, wanting to jump into the entrance of the cave where Ao Zhan was. In their opinion, Ao Zhan, who has no cultivation and is poisoned in his body, cannot pose a threat at all.

"Get down!" Ao Zhan burst into a shout as he kicked out like lightning.

This powerful kick instantly kicked the chest of the lightly attacked Iron Family Warrior, kicking him down and smashing him to the ground. He vomited blood, his bloodshot eyes widened, and his pupils were full of surprise.

"Beware, he hid it before!" Tie Lan glared at the Iron Barbarian.

"No way! I've checked, he doesn't cultivate at all!"

"Idiot, he must have a treasure of suppressive power!Tie Feng, capture him!" Tie Lan shouted, flipped his hand and took out the Heavenly Witch Drum, and shook it violently.

The Iron Family warrior who landed at the entrance of the cave had a cold face and waved his sword casually. He had already heard the sound of the Heavenly Witch Drum, and he was not worried about Ao Zhan's resistance at all.

"Hehe, do you think I'm still subject to Gu poison?" Ao Zhan saw through Tie Feng's mind and sneered with a smile.

"Why are you ......" Tie Feng's face was full of consternation.

"You go and ask Hades!" Ao Zhan yelled, stabbing out at the same time.

"You're looking for death!" Tie Feng was momentarily stunned, and his anger burned again.

He also stabbed it out!

Facing the extremely fast enlarged sharp knife, Ao Zhan pinched it with his left hand, causing Tie Feng to freeze his body.

Almost at the same time, Tie Feng, who was facing a life-and-death decision, let go of the back side, and the knife that should have pierced his heart was only pierced in the shoulder.

"You, you ......" Tie Feng covered his wound and looked at Ao Zhan in horror.

Ao Zhan was still holding the war knife tightly at the moment, blood was spilling on his left hand, he was smiling strangely, and a frenzy flashed in his eyes.

A strong sense of fear surged in Tie Feng's heart, he felt as if he was being stared at by a bloodthirsty beast, and the hairs on his body stood up.

Although Ao Zhan's cultivation is not high, he suppressed Tie Feng in terms of momentum.

Seeing that the other party's heart was in turmoil, Ao Zhan struck while the iron was hot, and suddenly launched an offensive, using his unique method - blood alchemy!

His blood-stained left hand clenched into a fist, and a wave of heat suddenly rose from inside the cave. At this time, Tie Feng was horrified to find that the blood around him began to flow wildly.

"What's the matter, how could I be like this, how could I be like this?!" Tie Feng's eyes widened, staring at his palms.

He could clearly feel that the blood in his whole body was boiling, as if he had received some kind of summons to burst out of his body.

He began to have convulsions, gradually losing control of his physical body, only to feel that his head was getting heavier and heavier, his spirit was getting more and more tired, and he could not even give birth to the desire to live.

Tie Feng's face became more and more pale, and a body of blood quickly rushed out of the blood hole in his shoulder, like a spiritual snake, surrounding Ao Zhan's side.

"Hey, congratulations on becoming the first person in the Netherworld to be refined by my blood, Blood Burst Technique!" Ao Zhan sneered, and his palm squeezed again, detonating the remaining blood of Tie Feng and exploding it into a pile of minced meat.

After Tie Feng died, most of the refined blood was condensed again, squirming around Ao Zhan's body. Ao Zhan excitedly picked up the storage bracelet in the flesh and blood, and took it in his hand without hesitation.

"It's a pity that there is another bracelet. Ao Zhan shook his head and looked at the Iron Family warrior who had been seriously injured by him earlier.

"Tiefeng?!"

There was a loud roar, but it was the Iron Barbarian and the others who jumped up when they heard the exclamation. The three of them smelled the bloody smell of the sky, and saw the minced meat all over the ground, and they couldn't help but churn in their stomachs.

"You killed Tie Feng?" Tie Lanqiao's face was cold.

"Did you believe me?" Ao Zhanwei laughed.

"Pretending to be a ghost, can you kill Tie Feng?" the iron barbarian didn't believe it. He prefers to believe that it was the Black Iron Knife Centipede who did it, and the grotto here is open enough for the Black Iron Knife Centipede to pass.

"Sister Lan, Tie Feng's bracelet is in his hand!" Tie Feng'er said with a frown.

"Hand it over!" Tie Lan also found out, and immediately roared.

", you have the ability to take it yourself. Ao Zhan scolded.

"You're looking for death!" Tie Lan was furious and took out the Heavenly Witch Drum and shook it violently.

"Ahhh

"Your Gu poison...... Why, how could it be?" Tie Lan was stunned, this was the first time her Heavenly Witch Drum had failed.

It stands to reason that Gu poison sneaks into the bloodstream, and if there is no antidote, it will be difficult to get rid of it for life.
