There were also huge stones falling down from above, and Liu Ao grabbed the ice silk and climbed up quickly.

Suddenly, Liu Ao felt the weight coming from behind him, and he caught a glimpse of Tong Ying, the girl, who actually followed, seeing that her face was full of panic, she actually stimulated her potential at this time, and her climbing speed was not much slower than Liu Hao.

Lei Mu also rushed over at this time, grabbed the ice silk and began to climb up, but a boulder smashed on his shoulder, causing him to vomit blood.

Finally, Liu Ao climbed out of the hole, but the rotating stone steps up still did not appear.

Tong Ying climbed up after him and said anxiously:

"It's going to collapse here, Brother Liu Ming, do you have anything you can do?"

Liu Ao's eyes were calm, and he began to look for the constantly shaking wall.

Seeing this, Tong Ying also hurriedly stepped forward to help.

Lei Mu climbed up covered in blood at this time, and he heard a 'boom' sound below, and he didn't need to think about it to know that the huge skeleton had completely collapsed.

As for Qi Guanyan and Yunqiu and his wife, most of them have no life to live again.

Suddenly, Liu Ao's hand touched a loose stone, and when he pressed it hard, he heard a "click", and steps began to stretch out on the stone wall.

"Let's go!"

Liu Ao let out a low roar and rushed up.

But it took too much time, and the violent shaking caused many steps to break and fall directly.

Liu Ao is in good shape and keeps jumping and climbing, but Tong Ying is only an intermediate martial artist, and he almost fell down several times.

At this time, once you fall, you will be buried here!

It was Lei Mu's performance that surprised Liu Ao a little.

Don't look at him covered in blood and missing an arm, but he gritted his teeth and jumped and tossed while dodging the stones that fell down, but he was not left behind.

When Liu Ao stepped on the last step and stood at the entrance of the passage again, he finally breathed a sigh of relief, and then ran outside.

The passage is not wide enough, and if it does collapse, there is really nowhere to hide.

In the dark passage, only the panicked footsteps of the three people and the sound of rapid breathing.

Finally, there was a light ahead.

Liu Ao didn't stop, and as soon as he rushed out, he pulled out the sword of Ao, turned around and stabbed into the cliff.

The figure kept falling, and Liu Ao's back was ground by the cliff and bloody.

But this can ensure that Liu Ao will not be smashed into a meatloaf when he lands.

After all, at this height, even if the Martial Spirit Realm falls, I am afraid that he will become a waste.

Just when Liu Ao thought that Tong Ying would be buried here, he saw Tong Ying suddenly throw out a purple soft whip from his cuff, and after wrapping around a boulder, he actually jumped off the cliff.

Liu Ao fell to the ground, his brows furrowed, looking at this posture, Tong Ying was probably about to break most of his bones.

"Help me!"

Tong Ying looked at Liu Ao with a pleading face, the long whip in his hand stiffened violently, and suddenly broke in the next moment!

Tong Ying exclaimed, and the speed of falling was a little faster.

Liu Ao stepped forward suddenly, jumped high, and caught Tong Ying with open arms.

The huge gravity hit Liu Ao's chest, and his arms seemed to be torn off.

Liu Ao snorted, and his body was smashed down.

But seeing Liu Ao bend his knees and fall to the ground, he unloaded most of the huge force, and his body rolled on the ground suddenly.

Despite this, Liu Ao still felt a sharp pain in his chest, and his arms seemed to no longer belong to him.

"Bang!"

There was a loud bang.

Liu Ao looked back in pain, and saw Lei Mu falling heavily on the ground, his body began to twitch, and blood kept gushing out of his mouth.

His axe was still stuck five feet high on the cliff wall, and he held the Taurus Demon Pill tightly in his hand, and his face was extremely painful.

Liu Ao stood up and slowly walked towards Lei Mu.

Lei Mu struggled to crawl back, his eyes full of unwillingness, "The demon pill is mine!"

"You can't be greedy," Liu Ao frowned, "You should know that I didn't stop you from escaping, and I already saved your life." ”

Lei Mu's eyes were bloodshot, and blood flowed out of his mouth.

"I know, but the demon pill still can't be given to you!"

Liu Ao snorted coldly, "Give me a reason." ”

The expression on Lei Mu's face finally softened a little, "I'm going to sell the demon pill and use it to buy the blood tonic pill for my mother's treatment." ”

Liu Ao said 'um', "Don't say I'm not kind, give me the demon pill, and I'll solve the matter of the blood tonic pill for you." ”

Lei Mu's face was hesitant, obviously not believing Liu Ao.

Liu Ao's eyes lit up, "You have no choice!"

Helpless, Lei Mu chose to compromise.

Shortly after the trio left, the canyon collapsed violently, leaving only a huge crater.

Hunter City, the Demon Hunters' Guild.

The old man who was cultivating cross-legged in a room opened his eyes suddenly, his face full of anger, "What a bold man, he actually broke into the Golden Bull Tomb!"

It turned out that the formation at the entrance of the Golden Bull Tomb had always been under monitoring, and as long as the formation was broken, it would be perceived by the people who arranged the formation.

And this old man is a fifth-level hunter of the Hunters Guild, a martial king cultivator, and a third-grade array mage.

Three days later.

The semi-monthly auction in Hunter City was held as scheduled at the Demon Hunter Guild Auction Hall.

But anyone from the Demon Hunter Guild can participate, which is also one of the purposes for Liu Ao to never leave Hunter City.

A few days ago, before he went to the Golden Bull Tomb, Liu Ao learned that there would be a mask auction in this auction.

This is the goal of Liu Ao to participate in the auction.

The auction of the Demon Hunter Guild also looks rough and atmospheric.

An open-air auction hall where tens of thousands of hunters gather.

In the midst of the crowd, Liu Ao stood in an inconspicuous corner, pulled the hat down, and waited quietly.

When a charming woman walks into the middle of the auction room, it means that the auction has officially begun.

Liu Ao was not interested in other things, and when the mask appeared, Liu Ao stared at the center of the field.

Then he saw the woman holding a thin silver mask in her hand, and said with a smile:

"This is one of the only three fourth-grade refiners in our guild, the mask refined by the predecessors of Tiemu, can change the appearance of a total of five times, the use of which I don't need to say more, if you like it, you can start bidding, and the starting price is a thousand spirit stones. ”

This starting price alone brought nine out of nine demon hunters on the scene back to reality.

This thing is good, but... I can't afford it!

"A thousand!"

"One thousand one!"

"One thousand three!"

Most of the people who bid for the price are high-level demon hunters, so they naturally have spirit stones to pay the bill.

By the time the price was called three thousand spirit stones, the voices were getting less and less, and only two middle-aged men were still competing against each other.

Just when everyone meant that this mask was about to be sold, Liu Ao suddenly spoke:

"I wonder if it's possible to barter?"

The woman in charge of the auction chuckled, "Naturally, you can." ”

Liu Ao nodded, "I have something that is inconvenient to display here, can you arrange it?"

"Then please follow me to the secret room," the woman pointed to a wooden house not far away, "and there is a professional assessor inside. ”

In everyone's attention, Liu Ao took a step, crossed the auction hall, and walked to the door of the wooden house.

Pushing the door in, I saw an old man with crane hair and a childish face sitting in this narrow room, drinking tea quietly.

"That mask is made of iron and wood, and it is very valuable, if the things you take out are not worth more than three thousand spirit stones, you don't need to take them out. ”

Liu Ao smiled lightly and took out two things from the storage bag.

One of them was the Taurus Demon Pill that constantly oozes cold air, making this room filled with a layer of mist.

The other is the disciple identity card handled by Liu Ao in Jiuding Academy as Jia Ming.

The old man's gaze fell on Liu Ao's identity card, and he couldn't help frowning, "Disciple of Jiuding Academy?"

Liu Ao nodded, "Isn't it possible for the disciples of Jiuding Academy to join the Demon Hunter Guild?"

The old man smiled, "Of course." ”

As he spoke, he looked at the demon pill in Liu Ao's right hand, the smile on his face suddenly froze, he got up suddenly, and let out a shocked voice:

"It's... Demon Pill!"

Liu Ao nodded, "It's the Demon Pill." ”

You must know that the demon clan that can form a demon pill is at least above the martial king, and the aura emitted by this golden bull demon pill makes the old man of the martial king feel terrified subconsciously.

"Wuhou Realm Demon Pill!"

"How? Can you change that mask?"

The old man swallowed his saliva and said in surprise:

"Would you really like to trade this treasure for that mask?"

Liu Ao shook his head slowly, "One mask is naturally not enough, I also need a bottle of blood replenishing pills, ten thousand spirit stones, and a pair of soft armor above level three." ”

The old man pondered for a moment and nodded, "The Blood Replenishing Pill is not a rare thing, ten thousand spirit stones are also a trivial matter, and there are soft armors above the third level, however, I still need to ask Tiemu if he is willing to exchange." ”

"Of course, if I am replaced, I am absolutely willing," the old man nodded, "you wait here, and I will go back as soon as I go." ”

About half an hour later, the old man returned.

Behind him was a middle-aged man, this middle-aged man was burly, his complexion was dark red, and he looked like a perennial smoke, which was the standard appearance of a refiner.

This person is the fourth-grade refiner, Tiemu.

As soon as he came in, he stared at the Taurus Demon Pill, and when he saw the identity card of the disciple of Jiuding Academy, he snorted coldly, "You are afraid that I will rob your Demon Pill and fail, so you don't need to use Jiuding Academy to press me." ”

Liu Ao's face remained unchanged, and he said with a smile:

"Walking outside, I have to pay more attention, not for seniors. ”

Tie Mu stared at the demon pill, and suddenly frowned, "How did you get this demon pill?"

"Senior, it's not important," Liu Ao chuckled:

"If you don't want to exchange, I'll take the demon pill and leave. ”

Tie Mu fell into deep thought, and suddenly stared at Liu Ao, "This is the demon pill of the demon golden bull!"

Liu Ao's face remained unchanged, "Yes, I don't care about any golden bulls and silver bulls." ”

Tiemu's eyes were sharp, as if he wanted to see something from Liu Ao's expression.

Seeing Liu Ao's indifferent expression, Tie Mu took out the mask expressionlessly, took out a bottle of blood replenishing pill, a silver soft armor, and a storage bag and handed it to Liu Ao, "Changed." ”

Liu Ao smiled freely and directly handed the demon pill to Tie Mu.

In fact, Liu Ao knew very well in his heart that the true value of the demon pill depended on refining it into an elixir, and strictly speaking, Liu Ao was at a loss.

However, Liu Ao also knew in his heart that the demon pill was a hot potato, and the longer it remained on his body, the more dangerous it became.

The so-called innocent husband is guilty of his crimes, this is the truth.
