At this time, in the extreme north, the chasm has long disappeared, and a circular crater appeared on the glacier, and hundreds of meters wide cracks radiated from around the crater, and the power of the explosion was felt almost everywhere on the continent.

Zhang Hao took the seriously injured Lu Li and hid underground thousands of meters away, and the terrorist explosion made them feel a kind of horror.

When some of them had calmed down, the two quietly appeared, and then rushed to the center of the explosion. When they arrived nearby, they were also shocked by the scene in front of them.

"It seems to be a bit loud!"

Looking at the huge pit under his feet, Zhang Hao grinned, he was only thinking about how to kill ten Dacheng Stage Blood Pythons, but he didn't expect that the entire twenty Tribulation Stage Demon Pills would be so terrifying after detonation.

The bottomless chasm is gone, and some broken flesh can be faintly seen in it. Looking at the tragic scene in front of him, Lu Li came back to his senses after a while, and hurriedly said: "The movement is a little bigger, go down quickly, no matter how late it is, I'm afraid it will attract other strong people!"

Hearing this, Zhang Hao reacted, and then hurriedly swept towards the depths of the giant pit with Lu Li.

When he got to the bottom, he spread out the vast soul energy, and searched nearby for a while before he found the ten Dacheng Stage Demon Pills.

The divine consciousness in these magic pills was all badly damaged, and they hid in the crevices of the rocks, obviously planning to escape later.

Zhang Hao found out the ten magic pills one by one, then used the Nine Shadows Heart Fire to refine the divine consciousness in them, and then after dividing them equally with Lu Li, he began to search for the entrance to the tomb of the powerhouse in the underworld.

However, the soul power searched nearby for a long time, and still did not find anything suspicious.

"Let's find the entrance to the tomb from a different angle!"

Lu Li put away the five Dacheng Stage Magic Pills, his gaze scanned around for a moment, and suddenly paused on the blue chains that were half-exposed in the cracks in the rocks.

Seeing this, Zhang Hao also understood that even if there was any entrance here, it would be flattened by the explosion, and ordinary methods would obviously not work.

If it were someone else, there might be no other way to think about it, but he couldn't do it, seeing Lu Li's gaze paused on the blue chain, his heart suddenly suddenly, and then he flashed to the front, and the escape method rose and melted into the rock.

Before entering the rock, Zhang Hao did not leave in a hurry, but used a black war knife to cut off the nearby blue chain and put it away.

Lu Li immediately understood what he was doing, and couldn't help but shake his head, even if those strong people who rushed over after hearing the news found that something was wrong here, it would be difficult to see the flaws again.

The two of them followed the blue chains hidden in the rocks, and went straight down for nearly half an hour before they appeared in an underground cavern.

Looking at the scene that appeared in front of him, Zhang Hao's face showed a look of surprise, and Lu Li was no better than him, constantly looking at the cave with his mouth open.

Blue chains, piercing through the rocks above, stretched deep along the top of the cave, but on the stone walls around the cave, there were some spirit stones, emitting soft light.

There are also battle scenes carved on the stone wall near the two, and the people in the pictures all have unimaginable magical powers.

Zhang Hao's gaze stayed on one of the paintings, and he saw a middle-aged man carved on it, with a mark on his hands, and the people near him all had painful expressions on their faces.

However, Zhang Hao didn't pay attention to the expressions on the faces of those people, his eyes were firmly fixed on the mark in the middle-aged man's hand, and after a while, he said slowly: "Wraith Seal!"

In the picture carved on the stone wall, the mark on the hand of the middle-aged man is the underworld seal method taught to him by Ling'er. Once this seal method is cast, it can forcibly extract the soul origin of the cultivator.

Lu Li's eyes were scanning the pictures on the rock wall, and when he heard his voice, he hurriedly turned his gaze.

However, at this moment, a terrifying aura suddenly appeared on Zhang Hao's body, which was full of coercion, and even he felt unbearable.

Not long after this breath appeared, a woman's figure suddenly appeared in the cave, the green dress continued to flutter with the terrifying aura, mixed with a strand of purple hair without wind, and the originally delicate cheeks were full of cold at this time.

A pair of lilac pupils, staring closely at the picture in front of him, what is even more strange is that the pictures carved on the rock wall seem to suddenly come to life at this time, and under the pale white light of those spirit stones, they begin to change.

"Ling'er, you...... You're finally awake?"

The changing pictures on the rock wall did not attract Zhang Hao's attention, his eyes were fixed on the girl, and his voice was full of excitement.

Lu Li was already suppressed by this terrifying aura at this time, and it was difficult to speak.

Ling'er didn't seem to hear Zhang Hao's call, just stared at those rock paintings, and after a while, frowned and said, "Where is this?"

"The Tomb of the Underworld Powerhouse!" Seeing this, Zhang Hao sighed and told the story of coming here.

But the little girl didn't seem interested in this, with a trace of confusion on her face, and said, "Who are you?"

This sentence suddenly made Zhang Hao stunned, and after a while, he smiled dryly: "Little girl, it's time to joke, now I'm not in the mood to play with you!"

But Ling'er still said in a cold voice: "I'm not joking with you, who are you? Who am I?"

This time, Zhang Hao also noticed that something was wrong, the coquettish look on the little girl's face disappeared at this time, and a deep confusion made her look a little haggard.

At this moment, Lu Li, who was not far away, finally couldn't resist the pressure of the terrifying aura, and knelt on the ground with a plop; "Brother Wudao, can you put away her aura coercion first?"

But Ling'er glanced at him with an extremely indifferent look on her face: "Useless thing!"

Hearing this, Zhang Hao and Lu Li immediately looked at each other, and they didn't know how to speak for a while.

The little girl dropped this sentence, and regardless of the ugly faces of the two, she began to look at the reliefs along the stone wall.

The pictures carved and smashed into the rock wall tell of a terrible battle that was far beyond the limits of what a cultivator could reach.

At this moment, the picture seems to come to life, changing scenes one after another, and when those people inside are fighting, they casually wave a wave of energy, which is to shatter the space near the space.

Mountains and rivers collapsed in the battle, and countless people died like ants, the scene was shocking, but there was a trace of fear.

Unconsciously, Zhang Hao had already followed Ling'er to the last picture.

The middle-aged man in the picture is still the same, but this time he was besieged by dozens of strong men and finally died tragically.

And near those strong people, there were also some people in white clothes, and on the chests of these people were embroidered with a mountain peak pattern that reached into the sky.

When Zhang Hao saw that pattern, his face slowly became gloomy: "Jietian Pavilion, it seems that these should be the scenes of the great war thousands of years ago!"

"What do you know?"

Ling'er withdrew her gaze from the petroglyphs, looked at him coldly and asked. At this moment, the little girl seems to have changed a person, no longer coquettish and willful, and some are just indifferent.

Zhang Hao sighed, understanding that this girl might have forgotten what happened after she met her, and she couldn't help but feel a little sad in her heart.

After pondering for a moment, he told him what he had heard from Lingxuzi about the great war a thousand years ago.

When Ling'er heard the word Underworld, the expression on her face obviously fluctuated, and then she asked in a cold voice, "Is what you said true?"

Hearing this, Zhang Hao couldn't help but snort and scolded: "Although Lao Tzu usually likes to lie, he has never told you a lie, if you don't believe it, I can't help it!"

Ling'er didn't pay attention to his sworn words, but tilted her head to Lu Li, and snorted coldly: "You come!"

Lu Li first glanced at Zhang Hao, and then said what he knew. What he knows is just passed down from others, so it's not very detailed.

The little girl had been quietly listening to Lu Li's story, and suddenly retracted the terrifying aura on her body, looked up at the top of the cave, and said, "There are some people rushing here, you two go with me!"

However, Zhang Hao looked up with a puzzled expression, and there was nothing else on it except for the hard black stone wall.

Just as he was about to speak, he suddenly felt several powerful auras appear above, among these auras, there were people he knew and people he had never seen before.

One after another, a huge divine consciousness kept scanning nearby.

But Ling'er only smiled coldly, and then waved a stream of soul energy and slammed it on those blue chains. The chains suddenly emitted a dark blue color, filling the entire cavern.

In the extreme north, above the giant pit, the space fluctuates slightly, and the Dark Demon Ancestor is the closest to here, but he is the last person to come.

He was accompanied by Magic Night, whose appearance immediately attracted the attention of the others.

The Black Demon Ancestor's gaze swept over more than a dozen strong people nearby, and finally stopped at an old man in a Taoist robe, and said with a strange smile: "Miscellaneous old Dao, I didn't expect that I haven't seen you for more than three hundred years, you are still alive, it seems that the bullshit Dao Sect is really a good place to raise people!"

"Hmph, old devil, I was lucky to spare your life back then, but now I still don't repent, and today the old man will completely eradicate your demon on behalf of the righteous people!"

Not far away, the old man in the Taoist robe sneered, and a huge amount of energy immediately gushed out from his body, blasting towards the Black Demon Ancestor.

However, Lao Motu glanced at him lightly, and snorted: "Magic Night, help the ancestor keep an eye on those guys, today I want to see how far this old miscellaneous hair has reached!"

As soon as the words fell, the Black Demon Ancestor actually rushed forward against that huge energy, and the terrifying aura instantly poured out of his body and collided with it.

"Boom!"

A huge roar suddenly erupted in mid-air, and more than a dozen strong people nearby had no intention of continuing to search and watch the two fight.

At this moment, the space fluctuated again, Tian Ze appeared nearby with an indifferent expression, and when he saw the Black Demon Ancestor's murder, he couldn't help but snort coldly: "Old Devil, Hugh is rampant, the Pavilion Master will send you back to the West today!"

As soon as the cold snort fell, he raised his palm and slapped it wildly towards the Black Demon Ancestor, and the huge palm print slammed into it with a violent sonic boom.

Just as the magic night was about to make a move to stop it, the palm print suddenly exploded with a bang.

Immediately after, everyone saw a sturdy man appear in mid-air, his eyes swept over Tianze with a look of contempt, and laughed: "Receiving the Heavenly Pavilion Pavilion Master in a dignified manner, it is so graceless, no wonder your group of disciples often sneak attack behind their backs, the battle between Lingyangzi and the old black devil, you better not interfere!"

"Mo Fei, do you want to stand with the old devil?" Hearing this, Tian Ze's face suddenly became gloomy, and his eyes stared at the strong man opposite, and shouted angrily.

Those who can get here in a short period of time are all strong people in the Dacheng stage, and these people are all overlords. But at this time, as soon as they met here, they had a big fight.

As soon as Tian Ze's words fell, the space around him fluctuated slightly, and a thin and tall middle-aged man suddenly flashed, and Sen Ran smiled: "Hall Master Mo, this is not your Demon Cloud Palace, I'm afraid it's not good to meddle in other people's affairs, or maybe this gentleman will accompany you through two moves?"

"Hehe, it turned out to be you, the splashed loach, what's the matter, finally planning to join forces with Jietian Pavilion?"

Seeing that the person who came was the Demon Jiao Xingjun, the palace master of the Nine Star Palace in the open sea, he couldn't help but mock.

But a cold voice slowly sounded: "I will accept the life of this loach!"

As the cold voice fell, a woman in a light blue dress suddenly appeared in ......
