A small dark tower was suspended in the cave out of thin air, and Ling'er looked at it, but was muttering something with words.

Lingxuzi stood aside and shook his head, just now when he proposed to find another kind of flame like the one in Zhang Hao's body, he also thought of this small tower.

However, when the two of them rushed back to the cave and took the small tower out of the dimensional ring, they realized that things were not as simple as they imagined.

Without Zhang Hao's consent, no one could approach this small tower, and even Ling'er, who had cultivated to an unfathomable level, had no way at the moment.

After trying many times to no avail, the two couldn't help but be a little discouraged.

"Old man, your good apprentice is going to die, don't you really care?"

Ling'er muttered for a moment with words in her mouth, and suddenly shouted with wide eyes.

Lingxuzi was startled by her shout, and thought that Ling'er wanted to run away in anger.

But at this moment, the pitch-black tower suspended out of thin air suddenly emitted a black light, and then enveloped Ling'er in it.

This scene appeared extremely abruptly, and even Lingxuzi didn't notice it in advance, until Ling'er disappeared in front of him, he reacted, and said with a shocked face: "Succeeded?"

Unfortunately, no one in the cave responded except for the small tower that was floating out of thin air.

After waiting quietly for a stick of incense, Ling'er returned here. Seeing this, Lingxuzi just wanted to ask something, but the little girl disappeared in front of her in an instant.

Looking at the cave where he was the only one left, the old man sighed again and again. But when Ling'er came back again, she was carrying Zhang Hao, who was already unconscious, in her hand.

It seems that this girl used some violent means.

Lingxuzi hurriedly stepped forward and asked, "Master, what are you ......?"

The little girl didn't seem to have the heart to explain to him, and said coldly: "Follow me!"

Seeing this, Lingxuzi didn't dare to ask anything, so he followed behind her in response.

When the two of them approached the small tower, a black light curtain suddenly enveloped them, and the next moment, Lingxuzi found himself on the first floor of the Hongmeng Fire Tower.

But at this moment, there was an old man standing at the entrance, and his face was blurred, as if an invisible energy was distorting the space near him at any time.

It's close at hand, but when you look closely, there's a haze.

Lingxuzi looked at the old man with a shocked expression, and asked Ling'er, "Master, is this ......?"

"See for yourself, old man!"

Ling'er didn't pay attention to him, but gently put Zhang Hao on the ground and snorted at the old man.

And the old man didn't talk to the two of them, he walked directly to Zhang Hao's side, grabbed his hand and invaded a trace of soul power, and after a while, a smile suddenly appeared on his face, and said, "It's okay, he can still be saved!"

When Lingxuzi heard this person use such an affirmative tone, he was somewhat disapproving, even he, a former alchemy master, didn't dare to guarantee it, why did he say that?

"How sure are you?"

Ling'er didn't have the slightest respect for the old man, and when she heard this, she immediately asked with her eyes fixed.

The old man with a vague face groaned, and then smiled: "Ten layers!"

Hearing this reply, the little girl was obviously relieved, turned her head and said to Lingxuzi: "We will wait here, if he dares to lie to me...... Hmph!"

At the end of the words, there was a little threat, but the old man shook his head with a smile, waved his hand lightly, and Zhang Hao disappeared at the same time as him.

An ethereal and desolate voice sounded at this time: "Don't worry, girl, he is a disciple of the old man, and the old man will naturally not let him have an accident!"

"Master, who is he?"

It wasn't until he was sure that the old man had disappeared that Lingxuzi asked softly.

But Ling'er dropped a sentence without looking back, turned around and walked towards the depths of the Hongmeng Fire Tower: "I don't know, if you want to know, ask yourself!"

Lingxuzi shook his head helplessly, stayed here, and took out the mountains and rivers again. Since Zhang Hao's affairs don't need him to worry about, it is better to do something interesting to pass the time.

The fourth floor of the Hongmeng Fire Tower, if according to the normal way, if Zhang Hao wants to get here, he must first subdue the Yin and Yang Fire on the third floor.

But the old man was able to come and go freely in this Hongmeng Fire Tower, and at this moment, he was directly brought here.

Standing next to the stone monument at the entrance, the old man sighed softly and said in a tone full of desolation: "The fire of reincarnation, the burning of gods and refining knowledge, the reincarnation of eternity, the illusion is born from the heart, I hope you can understand something from it!"

When the words fell, I saw that the old man just lifted Zhang Hao up out of thin air, and slowly sent it in, just when Zhang Hao's figure just exceeded the boundary of the stone tablet, a gray flame suddenly appeared on him, this flame gave people an ethereal and illusory feeling, obviously burning in front of him, but there was no trace of heat coming.

It's as if that kind of fire is separated from people by thousands of mountains and rivers.

Zhang Hao's body suddenly gushed out with a blood-colored mist, and after these blood-colored mist touched the gray flames, they erupted into a sneering sound, and disappeared in the blink of an eye.

At the same time, Zhang Hao's eyes also opened suddenly, and his pupils, which were filled with blood-colored light, exuded a demonic light.

The moment his eyes opened, a ferocious aura was released from his body like an ancient beast awakening.

When the old man saw it, his brows furrowed slightly, and he immediately waved his hand casually, and the gray flames that swirled around Zhang Hao's body suddenly released a terrifying temperature.

Obviously, the kind of gray flame that had no temperature just now was deliberately suppressed by him, but he was able to control the fire to such a point where he could do whatever he wanted, and his cultivation must have reached a terrifying realm.

"Demon demon, hehe, if there is no fire of reincarnation, the old man will indeed have to work hard!"

The old man with a vague face smiled slightly, and then turned around and left the place. The gray flames continued to burn the bloody demonic qi in Zhang Hao's body, and even his body was burned apart by this flame.

Bright red flesh and blood came out from under the cracked skin, but he seemed to be unaware of it, and kept chanting Zheng Yun's name in his mouth, and occasionally let out a hoarse voice: "Kill ......"

This is a world of blood, a sea of blood in the eyes, Zhang Hao stood alone in it, but a voice echoed softly in his mind: "Kill, kill all the qiē, only by killing them, can you live......"

The voice seemed to have a magical power that kept his mind falling.

A figure suddenly appeared in the sea of blood, and this figure had the same appearance as him, but its eyes were as deep black as before.

And the voice continued: "Kill him, you can only get out of here if you kill him!"

"Kill!"

Zhang Hao suddenly let out a roar from his mouth, and then rushed towards the figure exactly like him......

And the voice laughed in his head, as if he was about to see the bloody scene.

But at this moment, a gray flame suddenly appeared in Zhang Hao's mind, and the laughter suddenly stopped, followed by an unwilling roar.

At the same time, the blood-colored evil qi surging on Zhang Hao's body became heavier and heavier, as if he was trying his best to resist the invasion of that gray flame.

But the fire of reincarnation has the ability to incinerate the divine consciousness, but it is immediately revealed, and no matter how angry the demon who controls Zhang Hao's mind roars, it cannot resist this incineration.

The blood-colored glow in the evil aura faded and faded, and finally gradually receded.

Zheng Yun ...... Why?"

Zhang Hao, who was surrounded by gray flames on his body, stood there as if he had woken up, and asked in a muttered voice.

But in the next moment, the blood-colored light in his body surged again, and once this blood-colored light appeared, the little sanity that Zhang Hao had just returned was immediately occupied again, and an ugly roar came out of his mouth: "Kill...... Kill you......"

Time passed quietly under such circumstances, and I don't know how long it took, the smell of blood on Zhang Hao's body seemed to have faded a lot, and even the blood-colored brilliance in his eyes gradually dimmed.

And the gray flame that swirled around him was slowly extinguishing.

The old man who had left earlier suddenly appeared again when the flame of reincarnation was about to be extinguished, and with a slight wave of his palm on Zhang Hao's body, he immediately staggered and took a step forward.

The flame of reincarnation, which was about to be extinguished, burned again, and the terrifying temperature suddenly made his face twist and snort.

After hearing this muffled snort, the old man with a vague face nodded: "It's good to know the pain, hehe, how long does the old man think you can last!"

The mysterious old man said "you!" I don't know if he was talking about Zhang Hao or the demon in his body, in short, after dropping this sentence, he left this place again.

Ling'er circled between the first and third floors of the Hongmeng Fire Tower, but she didn't see Zhang Hao and the mysterious old man, and her face couldn't help but be a little annoyed.

Lingxuzi was concentrating on alchemy, and when he saw the little girl walking towards here with a menacing attitude, his heart suddenly sank. It doesn't matter if there are fluctuations in the heart, but there is a sudden bang in the mountains and rivers, obviously this furnace of elixir has been scrapped.

Ling'er was worried that she couldn't find an outlet, and when she saw that a good furnace of pills was scrapped like this, she immediately roared angrily: "Old man, today this girl wants to teach you how to concentrate on alchemy!"

"Master, I'm ......"

Lingxuzi saw that something bad was going to happen, so he hurriedly jumped up from the ground and hid behind the mountains and rivers, with a bitter face on his face.

At this moment, the mysterious old man suddenly appeared nearby and said with a smile: "The little girl is not very old, but her anger is not small!"

Ling'er, who wanted to be angry, saw this old man, the anger on his face suddenly disappeared, and he hurriedly asked with a smile, "How is he?"

At this time, Lingxuzi also breathed a sigh of relief in his heart, and listened carefully.

"Don't worry, it's just a demon that has just formed, and he will be healed soon!"

The mysterious old man smiled and nodded, then turned to look at Lingxuzi and asked, "Are you an alchemist?"

When he said this, his tone seemed to be asking the elders, but Lingxuzi didn't dare to slack off in the slightest, and nodded hurriedly: "Old ...... I've dabbled a little bit in the next!"

originally wanted to call himself an old man, but when he saw that the other party was not young, Lingxuzi hurriedly changed his words.

"Do you have the elixir you need for the Heavenly Tribulation Pill?"

The mysterious old man didn't care about the change in his title, but asked with a smile.

But Ling Xuzi's brows immediately furrowed, and after a while, he shook his head: "Forgive me for being lonely, I don't know how many pills this Heavenly Tribulation Pill is?"

He has a strong confidence in his alchemy, but Ling Xuzi just thought back to what he had learned all his life, and he had never heard of any Heavenly Tribulation Pill, so he was not convinced, so he spoke sarcastically.

"Hehe, it's also the old man who is confused!"

However, the mysterious old man didn't take his ridicule to heart, and shook his head with a smile: "How could such a thing as the Heavenly Tribulation Pill appear in the cultivation realm!"

When Lingxuzi heard this, his heart jumped slightly, and he hurriedly said, "Could it be that the predecessor is also an alchemist?"

The old man's unintentional words just now seemed to make Ling Xuzi guess something, and his tone became much more respectful when he asked.

"Alchemist?"

Hearing this, the mysterious old man shook his head: "It was many years ago!"

Speaking of this, he seemed to fall into a memory, and stood there quietly, until a while later, he smiled and sighed: "What did the old man do with you, do you have the elixir you need to cross the Tribulation Pill there?"

However, when Lingxuzi heard this, he was stunned for a moment, and it took a long time before his eyes suddenly widened, and his expression was shocked: "Is the Tribulation Pill in your mouth a kind of elixir that can help cultivators survive the Tribulation......
