It's a valley with green grass, fragrant scenery and a paradise.

"Everyone, be careful, something isn't quite right here."

Suddenly, Elder Xuan Ming reminded in a low voice.

"Hmm."

Everyone nodded, cautious.

Elder Xuan Ming was the leader of this team, and in their hearts, he had an extraordinary status, so after hearing his words, everyone gathered their minds and became cautiously guarded.

At this moment, the voice of the mysterious old man came:

"Junior, you are finally here, I buried the Heavenly Sect, and I was finally remembered!"

Before the words fell, the originally silent valley became extremely lively, and under the ground, countless demonic qi erupted, like the gates of hell were open, revealing an evil and gloomy smell.

Suddenly, a door opened, and a skeleton shelf flew out of it, all black and swirling with demonic mist, as if thousands of ghosts were condensed, hideous and terrifying.

This skull shelf, about seven feet in size, stands there, giving people an incomparable sense of oppression.

"It's ......"

Lin Han looked at the skeleton with a wary expression.

"Hahaha, don't be afraid. I am the Elder of the Burial Heaven Sect, and this Burial Heaven Ancient Mine was established by me. I know what you're here for, so there's no need to talk nonsense. If you want to enter the Burial Heaven Sect and get the ancestral weapon, you must go through the Seven Refining of the Burial Heaven! ”

The skeleton spoke, its voice hoarse, with a smell of decay and vicissitudes.

"Burial Heaven Seven Refining?"

Lin Han frowned.

"Exactly, the Seven Refinements of the Buried Heaven are presented to you in the form of a small world, and every trial has to enter a new small world."

skeleton says:

"I've been waiting for you for so long."

"But I still have to advise you not to go in, the Seven Refinements of the Burial Heaven, even the masters of the King Realm may not be able to clear the customs."

"You little babies, the cultivation time is short, the foundation is unstable, if you rush in, there is only a dead end."

Lin Han was slightly stunned, he didn't expect this Burial Heaven Seven Refining to be so dangerous.

"Thank you seniors for admonishing me, but I've made up my mind, and I hope my seniors can teach me."

Lin Han hugged his fists.

He is determined to obtain this Burial Heaven Ancestor Weapon, even if the front is full of unknown dangers, he will definitely not flinch.

What's more, this ancestral artifact is related to the life and death of human beings, and if it is snatched by the demon clan, human beings will definitely experience a catastrophe.

"Alas, in that case, then the old man will fulfill you, remember, your time is running out, miss this opportunity, you want to go in again, but there is no chance."

The skeleton sighed, and then, a majestic wave erupted from its body, surging like a volcano.

Immediately afterward, its body was as swift as a tiger, turning into an incomparably brilliant golden light, and rushing towards the mountains in front of it.

After approaching the center of the valley, its body suddenly swelled to a hundred feet, like a giant mountain lying there, and an unimaginable majesty was released, shaking the Eight Desolations.

As soon as it stepped down, a thunderous sound rang out in the void, and a dull explosion resounded.

Immediately afterwards, in the middle of the valley, a monstrous dust was suddenly lifted, and the ground cracked, as if a mountain and river had collapsed.

"It's amazing, is this a true element transformation?"

Elder Xuan Ming couldn't help but swallow his saliva in surprise and said in shock.

Although he knew that this skeleton was the former ancestor of the Burial Heaven Sect, he still felt unbelievable when he witnessed this scene with his own eyes.

This kind of method is really too rebellious.

"This is the true element transformation, a means that only those who reach the king have."

"It seems that the collapse of the Heavenly Sect is not such a simple thing, and it is likely to hide a lost history."

"Otherwise, it is impossible for an ancient inheritance like the Burial Heaven Sect to be destroyed."

Everyone gritted their teeth.

Lin Han looked ahead and shouted at the skeleton:

"Senior, what are the trial methods of the Seven Refining of the Burial Heaven?"

"Haha, I can only tell you that the Seven Refinements of the Burial Heaven are that there are seven small worlds, among which there are trial methods. As for what it is, it's up to you to make it! ”

As soon as the words fell, the skeleton roared in the sky, and then its eyes shot out two extremely bright beams, straight into the nine clouds, as if piercing the sky, causing the resonance of the heavens and stars.

In those two bright beams, there was actually a trace of blood mixed in!

"What a strong evil aura!"

Lin Han was surprised, the evil aura contained in those two beams of light was too strong and terrifying.

"This is the first refining of the Seven Refining of the Buried Heaven - Red Refining, and you have to cross this sea of lava. Only strong warriors can win! ”

The skeleton shouted.

The next moment, the whole land shook violently, and immediately after, a blazing lava lake appeared, exuding a reddish-brown luster, like blood burning.

"Red Refinement!" Lin Han's pupils shrank suddenly.

This is the most dangerous area of the Red Flame Mountain, the magma bred by the fire aura of the Red Flame Mountain, the temperature is extremely high, and ordinary people will melt in an instant when they enter, turning into a pool of blood.

"Ahhh......h

Without hesitation, a group of people flexed their defenses against the lava lake as they desperately fled.

This lava lake is not too far away from them.

But Rao is like this, that kind of scorching temperature still makes people's skin hot and muscles painful, and even some weaker disciples, there is a layer of flames jumping on the surface of their bodies.

Their speed slowed down considerably, and every step they stepped on the rocks made a squeaky sound.

"Juniors, go. Whether you can pass the trial and get the ancestral weapon depends on your creation! ”

The skeleton grinned and showed a row of white teeth, and he smiled.

Lin Han nodded with a wry smile, then jumped into the lava lake.

The fire poison contained in this lake is very deep, and ordinary warriors, even if they are contaminated, will be burned alive.

Fortunately, he has a special physique and has the blessing of the Hongmeng Divine Body, otherwise he would have been left with no bones in the other person's body.

After entering the lake, an extremely terrifying high temperature suddenly swept over, making Lin Han's hairs stand on end.

The surrounding lake water is boiling violently, like boiling water, gurgling and bubbling.

As soon as Lin Han's feet touched the lake, it was as if he had stepped on a soldering iron, and there was a burning sensation.

The soles of his feet were almost burned out, and drops of scarlet blood flowed out.

"What a lake!"

Lin Han gasped, cold sweat dripping on his forehead.

It was one of the most insurmountable tests in the Burial Heaven Ancient Mine, and just by just coming in, he almost burned the soles of his feet.

"Boy, you can't hold on for long, hurry up and urge your divine power to protect yourself."

Elder Xuan Ming reminded.

"Good!"

Lin Han nodded, sat cross-legged in the lake, mobilized the Hongmeng Refining Divine Technique in his body, and wrapped his body.
