In the darkness of the underground canyon, a cliff wall was illuminated by the glow of a silver fire, revealing a stone door hidden beneath the insects.

On both sides of the stone gate, there is a stone sculpture of a demonic beast prostrate, with the beast's mouth wide open, as if it is roaring.

Xiao Tenglong's face changed slightly, and he was immediately covered up, and said lightly: "Go in and have a look!"

With that, he took the lead and walked under the stone gate and tried to push it open, but behind the stone gate, it seemed to block the entire mountain wall, and after pushing it for a long time, there was not the slightest gap.

"Get out of the way!" Zhang Hao suddenly shouted, and then slashed down the center of the stone gate, the knife seemed to be unhindered, disappeared behind the stone gate, accompanied by a slight shaking, the stone gate in front of him slowly fell.

Seeing this, a trace of anger flashed on Xiao Tenglong's face, but because Zhang Hao had strength, he was not good at attacking, so he could only suppress the anger in his heart and take the lead in walking.

There was a sudden rumbling sound in the canyon, and then, the whimpering sound appeared again, since the demon beast came out, this sound had not been heard again, and it suddenly sounded at this time, making people's hearts tense up instantly.

Zhang Hao glanced back, under the light of the silver fire, there was an overwhelming black tide surging behind him, in which the ghost crying wolf howl was endless.

Looks like the Netherworld Wind is blowing again!

Xiao Tenglong had already walked into the stone gate, and when he heard that sound, he beckoned him to hurry in and take refuge. And Zhang Hao took back the spark next to him and rushed in.

Kuroshio almost hit the stone wall against his back, and a stream of black gas poured in along the stone door. The two of them casually waved a wave of spiritual power to close the stone gate before they began to look here.

Behind the stone gate, there is a large hall with eighteen steps extending from the front, and at the end of the steps is a high platform.

At this moment, more than a dozen huge stone pillars stand on either side of them, and some moire patterns are carved on the surface. The dome of this hall is topped by stone pillars, and the entire hall is made of stone, which looks very quaint.

The two of them climbed the eighteen steps up the platform, and found a dead man sitting in the center, who looked old, his clothes were rotten, and now only skeletons remained.

Xiao Tenglong saw this skeleton, but his eyes changed, and he looked at Zhang Hao from time to time with the corner of his eye, but the other party always wore a ghost mask on his face, not to see what kind of expression it was.

Seeing this situation, Xiao Tenglong hesitated for a moment and said with a smile: "It seems that this person is cultivating here, I don't know why he went mad, and finally fell into a fall, hehe, speaking of which, you and I are his juniors, let's put away his bones and go out to find a place to bury them in the future!"

With this, Xiao Tenglong stepped forward and wanted to put the corpse into the ring.

But Zhang Hao suddenly sneered and said, "You're here for him, right?"

This sentence immediately made Xiao Tenglong stop there with a stiff expression, looked back at him, and said, "The old man just looks at him a little pitiful, if the little brother has any objections, he can raise them directly!"

But Zhang Hao didn't pay attention to him, but walked straight to the bones, took off one of the rings in his hand, and said, "It's okay!"

Seeing this, Xiao Tenglong's face suddenly became gloomy, and his fists were slowly clenched. At that moment, the place where the skeleton was sitting suddenly sank downward, and soon, a hole leading to the bottom was revealed.

Xiao Tenglong suppressed the anger in his heart, and jumped into the cave first, but before he could land, there was a heavy buzz inside. The voice seemed to ring directly in his head, and a mouthful of blood immediately gushed out of his mouth.

Zhang Hao stood above with a calm expression, a silver flame wrapped around his hand, and the scene that happened below seemed to be unaware.

"Boom!"

An even dull bell rang from inside, and Xiao Tenglong's body was immediately covered with cracks. This is an extremely domineering sonic attack, if you don't cultivate enough, you will be shocked to death on the spot, and he can survive twice, which is already good.

"Boom!"

When the bell rang for the third time, a huge roar echoed throughout the stone hall. Xiao Tenglong, who was in the cave below, had blood flowing from his eyes, ears, mouth and nose at the same time.

At this time, Zhang Hao exhaled, jumped down like lightning, and threw it out.

"Boom!"

Immediately afterwards, the fourth bell rang, and Zhang Hao, who was standing below, immediately felt as if he had been hit by a heavy hammer in his chest, licked his throat, and a mouthful of blood gushed out.

This kind of sound wave, as soon as you get stuck in it for the first time, you will be trapped inside, and the bell rings again and again until it shatters your body.

Xiao Tenglong, who was thrown out of the stone cave, still did not come back to his senses from the bell just now, and lay there with his eyes blank, and the blood slowly oozing out of the seven orifices flowed on the ground, looking very terrifying.

"Boom!"

When the fifth bell rang, Zhang Hao's eyes immediately fell into darkness, and the bells echoed everywhere in his mind.

Almost instinctively, he urged the fire in the dantian to stir up, and the immortal starfire immediately enveloped him, and the silver flame caused the surrounding temperature to rise sharply, and the entire stone cave soon began to melt!

"Boom!"

The dull sound of the bell rang again, and this time, a ripple could be clearly seen in the air spreading from the depths of the cavern, and then slamming into the spark.

The silver flame fluctuated violently with a bang, resisting the sound wave, and Zhang Hao also eased up, coughed lightly, and his body immediately rushed towards the direction where the bell rang.

Whatever it was, it had to be stopped, or it would be stunned to death by a sound wave that was stronger than the other.

Zhang Hao's figure was extremely fast, and with just one breath, he rushed out hundreds of meters and stopped at the end of this stone cave, where a quaint big bell hung and a sloping stone platform under the bell mouth.

At the moment when Zhang Hao had just arrived here, the bell rang suddenly, and there was a deafening buzz on the quaint bell, and then he saw the sound waves surging out from above.

Almost instantly, a wave of terrifying fire enveloped him, and at the same time, the black sword in his hand swept towards the hanging above the bell.

The dull bell was just halfway rung when the giant bell fell!

There are many skeletons carved on the body of the clock, which looks very demonic, and the height of Zhang Hao is almost the same as that of Zhang Hao when it falls to the ground, and the whole presents a dark gold, full of ancient atmosphere.

It had reached the end of the cave, and there was nothing but the bell, and the sound of the bell had disappeared with it. Zhang Hao hesitated a little and then stepped forward to lift the bell.

Looking down, I found that it was empty, and there was nothing inside, and I couldn't help but wonder, what was it that rang it just now?

This place is full of weirdness, Zhang Hao didn't want to stay for a long time, so he simply put away the bell and turned around and returned to the stone hall.

And Xiao Tenglong is still unconscious, it seems that the previous sound wave has caused him a lot of damage.

There was nothing to be seen in the stone hall except for the stone pillars. Just when Zhang Hao frowned and was silent, a piano sound suddenly sounded outside.

At first, the sound of the piano gave people an ethereal inspiration, but in the blink of an eye, the sound of the piano became rapid, with a strong killing intent in it.

Under this sound of the piano, even Zhang Hao's mind was shaken, his heart was full of rage, and various illusions gradually began to appear in front of him. The battlefield is full of carnage, with stumps and broken arms everywhere, blood staining the red dirt, and even the smell of blood in the dirt.

Thousands of people rushed at him with a sudden shout in the distance, drowning him like a torrent. That majestic momentum immediately attracted the killing side in his heart, and after slowly pulling out the black war knife on his back, he rushed towards those troops.

The endless killing made people fall deeper and deeper, and in the end, there was only one thought in their hearts, which was to tear everything they stood in front of them to pieces.

On the battlefield with a shouting that shook the sky, Zhang Hao stood in blood, holding the black war knife in his hand, and the corpses in front of him were already piled up, but people continued to rush forward, and then fell one after another.

The sound of the piano was not covered by the earth-shattering shout on this battlefield, as if someone was playing in your ear, Zhang Hao's eyes had become blood-red at some point, and his body was full of ferocious aura.

Just as he was deeply immersed in this killing, the sound of the piano suddenly changed, like mountains and flowing water, gradually calming his bloodthirsty heart.

I don't know how long later, there was a sudden silence in the stone hall, and Zhang Hao's eyes slowly opened as if he was standing there, the depths of his pupils were actually blood-like, and the black war knife on his back made a buzzing and trembling sound, as if he had just experienced a battle that excited him.

At this time, Zhang Hao's back was already soaked with cold sweat, and he was panting heavily, since he stepped into the cultivation realm, he had never encountered something that made him so wolf.

Especially in the continuous tempering of the Venerable Fire, his mind has long been as solid as a rock, but now in the face of this kind of piano sound, he is still unconsciously deep.

It wasn't until he gradually came to his senses that he turned his cold gaze to Shimen.

The sound of the piano just now came from outside the door, Zhang Hao picked up Xiao Tenglong, who was still unconscious, and rushed out with a dodge, but when he got outside, he was stunned.

Although it was still the same darkness in front of him, he could clearly feel that this was not the canyon he had come into.

A ray of spark rose from his palm, and the silver fire slowly illuminated the surroundings, and what appeared in front of him was an underground dark river, and the strange thing was that this dark river did not flow, as if it was imprisoned by something.

Walking along the rocky beach to the river, with the help of the silver flames, Zhang Hao realized that this was not actually a river, but a kind of stone river with flowing water lines.

If you hadn't seen it with your own eyes, it would have been hard to imagine that such a pattern of flowing water would have formed on the stone, as if the entire river had suddenly been petrified by some ability.

There was nothing else here except Shihe, Zhang Hao tried to walk over from above, but found that his feet had just stepped on the top of Shihe, but they slowly sank down, and a strong energy immediately poured into his body from under his feet.

"Spiritual power?" The moment this strong energy poured into his body, Zhang Hao found that the immortal spark immediately swept it into the dantian along the meridians.

As the Starfire was refined, it was discovered that this kind of energy was exactly the spiritual power required by the cultivators, and it was extremely pure.

As soon as he thought of this, Zhang Hao simply returned to the shore, put Xiao Tenglong down, and jumped into the stone river. The moment he sat down cross-legged, huge energy poured in like a tidal wave, much faster than absorbing the spiritual energy of heaven and earth and cultivating hard.

The Chaos Burning Heaven Determination immediately operated, and the tide of energy that poured into the body was carried by the exercises and continued to circulate in the meridians, and finally merged into the dantian space.

The three venerable fires hovering near Yuan Ying immediately released a huge wave of fire, engulfing the spiritual power that had entered here as quickly as possible.

"Boom!"

Zhang Hao, who was sitting on the stone river, suddenly burst out of a terrifying wave of fire on his body, illuminating the place brightly. Zunhuo continued to refine those petrified spiritual powers, so that they were absorbed by Zhang Hao more smoothly.

Time passed little by little, Xiao Tenglong, who was lying on the shore, frowned slightly, and then came to his senses, but when he saw the three flames on Zhang Hao's body, his face became cloudy.

After hesitating for a long time, Xiao Tenglong slowly stood up, quietly retreated, and soon disappeared into the stone gate, and did not come out for a long time.

And Zhang Hao obviously entered a state of retreat, and he didn't know anything about the outside world, only that he was desperately absorbing the spiritual power pouring into his body.

This state lasted for a whole year, and in this year, Xiao Tenglong never appeared again. The stone river had become much smaller before I knew it.

When Zhang Hao opened his eyes, he found that he had touched the bottom of the river. Xiao Tenglong was no longer nearby, which made him frown, and he withdrew the three kinds of flames that had been rising endlessly into his body, and then headed towards the stone gate.

The moment he stepped into the stone gate, the stone river suddenly let out a deafening rushing sound, and then it was swallowed up by a real torrent......
