This invisible barrier is related to the level of cultivation of the monks, as long as they reach the late Yuan Dan stage, they can easily break through. If the cultivation is insufficient, there are some powerful magic weapons in hand, and there are also considerable opportunities.

Han Shi stood in the distance, watching coldly, the clouds above his head seemed to be just a thin layer, but the power of heaven and earth contained in it was extremely powerful, and people who were not strong enough could not even take a step, and at the same time, with his eyesight, he had already discovered that there were countless caves on the surface of the giant peak, and the wind whistled out from time to time in these caves, and the inside of it was curved and uncertain, and he didn't know where it led, which was the same as the record in the jade slip.

Many monks who were not strong enough looked at the clouds ten zhang above their heads, and their eyes showed unwillingness.

After a long time, I still had to give up, and after retreating a distance, I chose a cave and walked in, after all, this is a once-in-a-century opportunity, and if I miss it, no one wants to.

With Han Shi's strength, it is not a problem to break through the clouds, but for him, at the moment, the most important thing is to collect the Thundercloud Order, judging from the records in the jade slip, at least eighteen are needed, and in addition to the two in his hand, there are still sixteen missing.

He stepped forward, turned into a streamer, and silently followed one of them into the cave, with his stealth skills, it was extremely difficult to be discovered, and at the same time, his right hand swiped in mid-air, and the shadow sword suddenly came out, this sword only appeared at the moment, and its outline could be seen vaguely, and it turned into invisible in less than half a breath, completely lost its trace, and it was difficult for ordinary monks to detect even if they used their spiritual sense.

After ten breaths, Han Shi walked out of the cave slowly, his face was calm, but there was an extra thing in his hand, which was the thundercloud order that originally belonged to the monk.

That person, Han Shi didn't take his life, just knocked him unconscious, after all, killing for no reason was not Han Shi's intention, it's just that after taking away the person's thundercloud order, an invisible force was generated from the void, and after taking the person into the air, it disappeared, obviously, after losing the thundercloud order, the repulsive power that triggered this thundercloud secret realm was teleported out.

Han Shi glanced at the thundercloud order in his hand, and a ray of essence suddenly burst out in his eyes, he hadn't looked at it carefully before, only that every thundercloud order was the same.

But after putting the three thundercloud orders together, he found that each thundercloud order has a slight difference from the other thundercloud orders, this difference, just like human skin, at first glance, there is no difference, but if you refine it, you can see the difference in texture.

After Han Shi pondered for a long time, he waved his sleeves and put the three thundercloud orders into the storage bag, at the moment, this difference didn't know what Han Shi meant, so he simply didn't think about it, and collected all the eighteen thundercloud orders first.

Ordinary Yuan Dan monks, to Han Shi, did not pose any threat, often did not even see Han Shi's figure, he was slapped on the vest by his palm, fainted.

These monks, how could they never have imagined that here, they would be remembered by a person whose strength is equivalent to that of the Yuanying monk, this is really a disaster, Han Shi has never killed these people, he is not a person who is easy to kill, but he has never been soft on those who have the opportunity to kill him, from the time he first appeared in the abandoned place, he killed the thief Hong Fei, you can see one or two.

Seeing the sixteenth person lying down softly in front of him, Han Shi exhaled lightly, this kind of forcible seizure always feels a little jerky to do, he shook his head and showed a wry smile, in the hands of this unconscious monk, there were actually four thundercloud orders, obviously this person snatched them, no wonder this person was able to make some reactions when Han Shi approached, this person's strength is indeed higher than other Yuandan monks.

In this way, in Han Shi's hands, there were a full twenty-one thundercloud orders, and after holding those four thundercloud orders in his hands, Han Shi turned his eyes and looked at the cave in front of him, he tracked this person here, in order to beware of this person finding out, unconsciously, at least a thousand feet away.

This cave, there are many bends in the curve, but in the end it still leads to the bottom, and the temperature around it also becomes cold as the terrain decreases, this cave is very strange, he exudes his spiritual consciousness into the depths, but only ten zhang, and then slowly dissipates, so that he cannot know the situation in the depths of this cave.

"Let me try to see if what is said in the jade slip is true or false. ”

A strange light flashed in Han Shi's eyes, and under the grasp of the void in his right hand, eighteen thundercloud orders suddenly rose out of thin air, and Han Shi's figure flashed rapidly, almost at the same time, a little above the eighteen thundercloud orders, and the positions of the points were different.

"Close!"

Han Shi grabbed it again, and eighteen thundercloud orders were sucked into his hand, arranged neatly, and his exuding spiritual consciousness gradually merged into it along the position he pointed.

After a while, he popped out a finger on the eighteen thundercloud orders, and suddenly flew out a faint phantom shadow, its shape, just like a small thundercloud order, seeing this thing appear, Han Shi's eyes lit up, which was completely consistent with the description in the jade slip, with this thing, he could guide the spiritual consciousness to the hidden place under this giant peak.

Han Shi's mind moved, a spiritual consciousness attached to the phantom, the phantom flickered, and flew towards the depths of the cave, the length of the cave is extremely long, and it extends in all directions, like a labyrinth, there are countless twists and turns, and the phantom is also constantly moving forward, gradually fading, weakening, just at the moment when the phantom is about to disappear completely, finally with the spiritual sense, rushed out of this almost endless cave.

Before he even had time to inquire about anything, he only felt an earth-shattering roar and an indescribable picture, and then disappeared completely.

Han Shi couldn't help but take three steps back, blood flowed from the corners of his mouth, this roar was not real, but sounded in his heart, in it, Han Shi heard anger and unwillingness, and even faintly called for help.

In that picture, Han Shi saw that a strange beast of thousands of zhang size was lying on the ground, if its shape was countless times smaller, it was very similar to the turtle, and the top of the beast's head had countless hideous sharp thorns, flashing cold light, this kind of sharp thorns not only had on the top of the head, but also on the limbs and tail, but from a distance, the back shell was very similar to the turtle shell, so it was easy to be mistaken for a turtle.

In the middle of the back of this beast, there is a dry skeleton sitting upright, and the hands are in a pinching posture, obviously this person died very suddenly, there must be something strange.

And on the ground where this beast is lying on the ground, there are countless thunderbolts flickering from time to time, the thinnest one, also has the thickness of the bowl, intertwined, forming a thunder net, this thunder net from time to time emitting a sizzling sound, at the same time, there is white smoke rising under the beast's body, disappearing under the drift, and this beast will also let out a slight tremble.

According to the appearance of this beast, it is very similar to the rumored Xuanwu, except that the limbs and head and neck of this beast are like a puddle of mud, clinging to the ground covered with thunder nets, as if there are no bones in it.

Han Shi groaned, subconsciously rubbed the thunder cloud order with his fingers, and the afterglow inadvertently swept the luster on the surface of the token, suddenly, his eyes changed, and an extremely bold conjecture arose in his heart, if he hadn't learned the secret in the gray jade slip, he wouldn't have such an idea.

Suddenly, a huge roar came, such a level of sound was by no means ordinary, Han Shi's complexion changed slightly, he turned around and took a step, and flew towards the outside of the cave at great speed, that Xuanwu also seemed to sense Han Shi's existence, and after letting out a few roars again, he fell silent.

Han Shi stepped out, and then came to the clouds above his head, his left hand was pushed out, and a mighty Yuan Force suddenly pierced through the clouds, and a hole the size of a zhang appeared, and his figure flashed, and he passed through the hole, and the hole, after Han Shi passed, was immediately covered by the nearby clouds again, as if it had never appeared.

Through the clouds, the entire mountain peak is in full view, although it is called the top of the mountain, but the land in front of you is still dozens of miles wide.

At this moment, a man in black stood in the air on the top of the mountain, pointing to the sky, just looking at this figure, there was a feeling of looking at the world, dozens of miles away from the man in black, there were several figures looking at the man in black, talking to each other in a low voice from time to time, but looking at the man in black without blinking, for fear of missing something.

I saw that with the man in black pointing in the air, in the endless sky, dark clouds suddenly appeared from the void, and once these dark clouds appeared, they began to rotate with each other, and soon formed a huge whirlpool, and it was constantly getting bigger.

"Heavenly Tribulation, this person is going to spend the Tribulation here......"

Han Shi's face froze, he already knew that if he wanted to break through to the Yuanying realm, he had to cross the Five Elements Wind and Thunder Tribulation.

Regarding this tribulation, Wu Tian once told him about his own experience, so that he had some expectations for the tribulation, and today he can see the tribulation of others with his own eyes, and as a reference, he is confident that he will have ninety percent certainty to survive his five elements wind and thunder tribulation

The black-colored whirlpool kept expanding, and finally fixed at a radius of twenty miles.
