Wu Wei had just crossed the desert at this moment, standing on the edge of the desert, only to see that the road ahead was blocked by the black cliff again, which suddenly made him feel a sense of powerlessness.

Just when he was looking depressed, he suddenly saw a black beetle not far away digging through the black sand and burrowing out from the depths of the ground.

"Yes, since there is no way to go to the sky, then it is okay to enter the ground?" Thinking of this, Wu Wei's eyes suddenly lit up, and he regained his spirits.

These black beetles do not appear out of thin air, but emerge from the depths of the earth one by one, and eventually swarm and coalesce into a terrifying black hurricane.

A single black beetle is very weak, but the hurricane formed by thousands of black beetles is like a huge awl, and it can quickly drill a deep hole in the rock-solid depths of the earth.

"I don't know if that's going to be possible. After Wu Wei groaned slightly, he sacrificed the black short sword, attracting spiritual power to pour in, and suddenly the blue light was flourishing.

Relying on the gourd to draw the scoop, he used himself as the eye of the hurricane storm, and the blue light short sword swirled rapidly around his body, and finally formed a storm layer, and surprisingly, many black beetles that came out of the black sand involuntarily attached to it.

In just a moment, the black hurricane incarnated by Wu Wei was like a spider web full of black beetles, densely wrapped into a huge zongzi, on which there were bursts of palpitating buzzing sounds, and if you didn't probe carefully, you wouldn't know that someone was controlling it.

Wu Wei was in the center of the hurricane at the moment, he could naturally sense the changes outside his body, and with a movement of his mind, the black hurricane formed an extremely sharp impact force, breaking through the ground and breaking into the ground, all the way like a bamboo, almost unstoppable.

"How does it feel like digging your own grave," he sneered at himself as he controlled the eye of the hurricane.

In the end, I don't know how far I went in, Wu Wei only felt that the spiritual power consumption speed in his body was much faster than that of the previous Dao method, and he had doubts, but he had to speed up the speed of drilling into the ground.

"At this point, it is impossible to go back, and the top layer is a layer of sand, which collapses and buries soon after entering. At the moment, he didn't know how far he had gotten in, so he had to burrow deep into the earth with all his senses.

The deeper he goes into the ground, the more he can feel the hardness of the soil rock is getting bigger and bigger, if the front ten zhang is sand, then the next ten zhang is simply a sand and gravel layer, and it is easy for people to feel that Mount Tai is pressing the top in it.

Wu Wei's expression showed a trace of fatigue, and unconsciously drilled a distance of nearly 100 zhang, at this time, the hardness of the sand and gravel layer has exceeded several times that of ordinary rocks, and some of the attached black beetles have broken away, and some have died one by one under the rotation movement of this super load.

"Is it a road of no return?" At this time, Wu Wei was sweating profusely, exhausted, and his face became more and more pale, seeing that the beetles wrapped around his body had almost been exhausted, if he hadn't found an exit, then what was waiting for him would be suffocation in this boundless underground.

Finally, Wu Wei stopped at a hard rock formation, because after drilling here, it seemed that the rock layer in front of him had reached a critical point, no matter how hard he tried, he suddenly couldn't enter half an inch, and he didn't know how far he had gone into the ground in front of him.

"It's a self-digging grave. Wu Wei smiled bitterly for a while, and now he even felt a little cramped in his breathing, and the aura in his body had been exhausted.

Just when he was almost desperate, the old man in the storage bag suddenly said: "Stinky boy, don't drill, hurry up and blast the rock wall in front of me, I can feel a faint fluctuating breath." ”

"Why didn't you say it earlier?"

"Didn't I just find out!"

Wu Wei now felt that it was a waste of time to even take a breath, so without saying a word, he used the only trace of spiritual power left on the spiritual platform in his body, concentrated his palms, and blasted towards the black hard rock formation in front of him.

"Bang"

It's just that under this bang, there was only a dull sound from the ground, and the rock formation in front of him was still intact, and there was no exit.

"Naturally, I felt the breath coming from the other side of the rock wall, this breath is somewhat similar to the purple mist just now, it shouldn't be wrong. The old man of Yin Zhi said with a rare determination.

Wu Wei glanced at it, and stopped talking nonsense, took out several glorious spirit stones from the cloth bag on his waist, and swallowed them without hesitation, he didn't care too much about the use of this spirit stone, but at this moment it became his last life-saving straw.

If what the old man said is true, then it's okay to say, if he perceives wrongly, then waiting for him is buried deep in the ground forever, and the passage dug behind him is also strangely blocked again after the black beetles die one by one, as if it has never appeared.

Thinking about it this way, in the ground here, except for the black beetle that can penetrate it, perhaps any other great magic technique is estimated to be unable to break through it in the slightest, this guess was personally tried by Wu Wei when the black beetle died, so he was so desperate at this moment.

"It seems that we can only use Chaos Qi again. Wu Wei hesitated slightly, his eyes condensed slightly, the previous golden ocean had already shrunk into a small lake, he mobilized one of the few wisps of chaotic qi in the sea of consciousness, and his qi was like a dragon swimming into electricity, and he rushed towards the black rock wall.

"Bang"

Suddenly, there was a violent vibration in the entire underground, and the rock wall in front of him suddenly cracked, and a 'click' tearing sound came out, and a long crack appeared in front of him.

Wu Wei let out a long breath, and suddenly felt a sense of survival after a catastrophe, and at the same time, a refreshing warmth came in from the crack, this warmth was nothing else, just a trace of fresh air.

In front of him was a long passage that only allowed one person to crawl, and the passage led directly to a cave, Wu Wei did not hesitate to burrow into the passage and began to crawl towards the cave.

He could clearly feel the cold bones of the cave wall lying on the rock layer of the passage, and if he looked closely, the layers of rock layers like black jade were like stubborn stones that had been buried for tens of thousands of years.

Soon, he struggled to make his way out of the tunnel of the rock wall, and when he appeared, he was already in a dark open space, and through the faint light he realized that it was actually a small cavern.

It's just that there is silence in the cave, there is no breath fluctuation, and there is no so-called purple mist, and I don't know how the old man of Yin Zhi sensed the abnormality of this place just now, but the only thing to be thankful for is that he no longer has to hold back in the pitch-black rock formation.

"Since there is air circulating here, there must be an exit. Wu Wei crept forward and comforted himself like this. It's just that the cave in front of him is too quiet, so silent that Wu Wei can almost hear his heartbeat.

After feeling a few zhang away, he decided to meditate on the spot first to recover the spiritual power in his body, the spiritual power on the spiritual platform has been exhausted, he is now almost like a mortal with no power to restrain the chicken, until this moment, he really understands the importance of the spiritual stone to the monk.

I don't know how long it has been in this dark cave!

Wu Wei slowly opened his eyes from meditation, his divine sense spread out and swept around, but he still didn't find any movement, looking at the smooth cave in front of him, he suddenly remembered the scene when he was in the underground cave of the ancient battlefield of Leize.

The cavern structure here is almost identical to that there, except perhaps that there is no hot magma here.

After he pondered for a while, he immediately chose a passage to drill into, the size of each passage here was about seven feet, just enough for him to walk upright normally, compared to the dragon vein meridians of the day, this place seemed much narrower.
