In the midst of the earth, Zhang Yuanhao found that his spiritual sense sensing range could be increased with the changes in the terrain.

For example, with a granite layer of uniform density, Zhang Yuanhao's spiritual sense can more than double the sensing range, and even if it is a crystal layer or mudstone layer with uneven density distribution, he can also get a gain of three to fifty percent, which is not a surprise.

Moreover, in Dan Yuanzi's memory, if the earth escape supernatural power is combined with the pulse finding technique and the feng shui physiognomy technique, the power will be multiplied, and the monk can rely on his weak cultivation to attract the general trend of the mountains and rivers, and combine the feng shui phase to form a formation similar to the killing prohibition, and kill the enemy at a higher level.

It's a pity that these secret techniques are also extremely rare, and even such a huge foundation as the Medicine King Hall does not have a relevant collection of books, and can only be glimpsed through ancient books.

......

For a whole day, Zhang Yuanhao shuttled through countless rock formations, during which he encountered a lot of mineral deposits, but they were all relatively ordinary metal deposits or low-grade spirit stone veins, and Zhang Yuanhao couldn't look down on them at all.

However, in this process, Zhang Yuanhao unearthed a lot of good things, including several rare spiritual material ores, which are relatively rare in the outside world, and can only be distributed in the depths of the earth.

"Hey, why do you feel a little hot?"

Zhang Yuanhao was in a state of retreat, but he suddenly felt a burst of hot breath coming from front of him, which seemed to be somewhat familiar.

"The lava sea!"

Three big words immediately appeared in his mind, Zhang Yuanhao's eyes narrowed, he didn't think much about it, and immediately fled towards the place where the hot breath came from.

The more he fled there, the hotter Zhang Yuanhao felt, so he had to take out the purple Jiao Fire Fighting Crown from the storage ring and put it on his head, feeling the wisps of purple gas that kept hanging from the top of his head, and then turned into an earthy yellow streamer and continued to escape.

Swish!

Suddenly breaking through the rock formation in front of him, Zhang Yuanhao only felt that a red appeared in front of him, and the earth escape technique naturally dispersed, and his body floated in mid-air.

"Sea of Lava!"

Zhang Yuanhao took a deep breath of hot breath and looked around, but he couldn't see the edge.

Zhang Yuanhao came here, naturally with his intentions.

He was still thinking about the treasures in the Otogi Palace.

Now that he has the Earth Escape Technique, coupled with the ability of the Purple Jiao Fire Crown, he can confidently crisscross the underground world without hindrance, and in the face of the heavy treasures in the Yimu Palace, if he is not moved, it is naturally false.

Flying over the blazing lava sea, Zhang Yuanhao's heavenly eye technique blessed his eyes, and he tried his best to look into the distance, but he could only see the scene fifty miles away.

Promoted to build the foundation, the techniques used by the monks have also been greatly strengthened, and the Heavenly Eye Technique is one of them. Originally, I could see a scene about twelve or thirteen miles away, but now I can clearly see fifty miles away.

"That's ......"

Zhang Yuanhao flew at high speed, and suddenly his eyes lit up, and he saw a grand scene in the distance.

Through the Heavenly Eye Technique, Zhang Yuanhao could vaguely see a huge silhouette phantom fifty miles away, which seemed to be like a demon bird with wings spreading.

Because the sky over the lava sea was shrouded in red fire poison, like a thick fog in the sky, Zhang Yuanhao could only see a rough idea, and he couldn't completely see the appearance of the demon bird, but as soon as he saw this scene, he was full of excitement.

It's definitely the ancestral beast of the Golden Wing Tribe, the big demon named Mur Deer!

Zhang Yuanhao had already memorized its appearance in his mind, and just by seeing some outlines, he could outline its figure.

Gritting his teeth, Zhang Yuanhao shot in that direction.

Over the lava sea, hundreds of miles away.

In the smoke condensed by the crimson fire poison, a golden totem phantom flickered in it, its wings fluttered like a volley, a pair of fierce and strange pupils under its armpits, and a pair of giant claws gave birth to the wingtips, which looked hideous.

Three sturdy figures stood above the sea of red smoky lava, wearing beast robes branded with ancient textures, and simple leather boots on their feet, and their bodies were full of astonishing power, not like the mana of a monk in the Yudan Realm, but they were so powerful that they were suffocating.

The three of them trampled on a vast formation under their feet, and countless totemic methods derived from the formation, like ghosts, surrounded them, only to dissipate like smoke and dust after hitting their bronze skin engraved with strange sashimi.

Looking down at them, it was a different sight.

It was a crimson crater, bottomless, and only a faint red gas could be seen rising from it. Countless lava flows and pours into it, like a huge waterfall, and the endless lava is going nowhere.

And above the giant pit with a diameter of dozens of miles, there is a huge golden egg suspended, engraved on it with strange and simple patterns, and the golden eggshell seems to be made of metal, reflecting the magma rolling down, reflecting the egg body is red.

I saw three powerful monks look at each other, recite a string of obscure characters in their mouths, and then each pinch out a magic trick in their hands, standing silently in the air.

After a long time, three rays of blood light burst out from the chests of the three of them, carrying majestic essence qi and escaping into the golden giant egg floating above the lava crater, and disappeared in an instant.

After the three blood rays shot out, the momentum of the three people in the air was weakened, and the most aging person among them was even more pale as gold paper, and a weeping aura emanated from his body.

Slowly, Zhang Yuanhao's retreat approached the huge sinkhole in the lava sea, and suddenly, the retreat paused, and suddenly stopped.

"Shhh

With the blessing of the Heavenly Eye Technique, Zhang Yuanhao saw the earth-shattering pit more than forty miles away from a distance, and watched the infinite lava pour into it, forming a lava waterfall, and couldn't help but gasp.

The power of Lingbao's self-explosion can be seen.

"That big pit!"

Zhang Yuanhao looked at the huge crater that covered dozens of miles of lava sea with burning eyes, and muttered in his mouth.

Otogi Xinggong exploded by itself, although the center of the explosion was not aimed at the lava sea, but the aftermath also moved dozens of miles below it into a huge crater, Zhang Yuanhao really didn't know how he survived at that time.

Suddenly, his gaze moved, and he saw the golden giant egg floating above the lava waterfall and the three majestic figures that activated the magic circle in mid-air, with a thoughtful expression on his face.

Suddenly, more than forty miles away, a bald-headed and stout man stared at his eyes, as if he was aware of it, and glanced in the direction where Zhang Yuanhao was a little strange, and on the back of his head, a musk deer totem came to life.

Zhang Yuanhao almost looked at him, and quickly staggered his gaze and looked away, but a cold sweat broke out behind him.

It's dangerous!

If Zhang Yuanhao's gaze intersected with the strong man just now, he would definitely be locked in the direction by the latter in an instant, and he would definitely be unable to escape death at that time.

This is the horror of the Jie Dan Realm, or the Immortal Realm cultivators.
