The whole cave can be described as clean and tidy, not even a trace of dust, but there is only a small grass growing tenaciously in this dark corner.

"Third Master, why didn't you remove this little grass before?"

Li Mu turned his head and pointed to the small grass in the corner of the wall and said.

"Little grass, where is the grass, we've never seen any grass?"

The third master was a little surprised, and looked at Li Mu's fingers, only to see that there was a very thin grass there, as if it was a breeze blowing, and it was about to be uprooted.

Then the third master's eyes looked at the people behind him, and all of them shook their heads lightly after seeing the little grass, it seemed that they had never seen this little grass.

"Brother Li, is there any mystery in this little grass?"

The third master felt that there was something wrong with Li Mu's words, and then tentatively spoke, could it be that this little grass contained what kind of formation could not be achieved?

"Hehe, the existence of this tree proves that what I said before is not bad, every time you enter the cave is not the cave at the right time, so none of you have found this grass, but it is precisely because of this grass that we have not found the wrong place to find our way back. ”

Li Mu turned his head and said with a smile.

"You mean, this grass?"

The old lady on the side also looked at the grass with a puzzled face.

Although this old lady's cultivation had reached the consummation of the Breaking Dan Realm, his soul power was far less powerful than Li Mu's, so he didn't understand what that little grass represented at all.

"Old lady, you might as well take a closer look at where the roots of that little tree are, and you can also try to see if you can pull it out with all your might. ”

Li Mu smiled slightly, and then spoke mysteriously.

"I'll see!"

The old lady bent down and took a closer look at the little grass, and saw that the roots of the grass had grown directly in a rock without any gaps.

Then he raised his head suspiciously, and looked at Li Mu again, and the latter just smiled and nodded.

The old lady stretched out her hand, grabbed the two delicate green grass blades with her index finger and thumb, and gently plucked them.

"Huh?"

After exerting two fingers, the old lady realized that the tenacity of the little grass was far greater than its appearance. Immediately, he increased his strength, but the grass still did not move.

"It's weird!"

The old lady let go of his mouth and couldn't help but exclaim.

"I'll try!"

The third master stepped forward excitedly, Li Mu nodded slightly, and then the third master bent down and directly pulled the leaves of the grass vigorously and pulled it up.

But the grass remained unmoved.

"Xiao Li, what is the reason for this?"

The old lady asked with a smile, and he suddenly felt that there was this young man, and it seemed that they were really not far from leaving this space.

"Old lady, the reason is very simple, this stone wall is indeed connected to a place with a strong aura, and this little grass does not belong to our space, but to another space, in other words, this little grass does not exist in the first place!"

Li Mu's words completely stunned everyone present, this grass is not this space, why can two people completely seize it?

"Because that's just a projection of grass!"

When the words fell, Li Mu waved his arm slightly, and the grass disappeared completely!

"This.... How so!"

The people present immediately looked at the place where the grass grew, and they felt that everything they had seen today could be described as weird.

Of course, Li Mu naturally wouldn't tell them that it was Yinjing who found this grass abnormal, not him.

Li Mu discovered the time circle at the entrance of the cave, but he couldn't find the time circle in the cave, it seems that the energy of this space is indeed a serious chaos, so he will allude to all the formations closest to them.

"And how are we going to open this passage and go back?"

Hearing the third master's question, the people around them nodded in unison, because they were most concerned about this issue.

"All I can say is as much as possible, because I'm not sure!"

After speaking, Li Mu turned around, made a specific seal against the wall, and then slowly closed his eyes.

"Li Mu, you are now using your soul power to explore that stone wall, if you use your spiritual power to probe, they will not find the entrance to that passage even if they use it for hundreds of years!"

The voice of the silver mirror sounded in Li Mu's mind.

"Good!"

Then the soul power in the Mud Pill Palace slowly swam out, and then went towards the stone wall.

"Hmm!"

When Li Mu's soul power had just touched the stone wall, a stinging pain was transmitted in an instant, making Li Mu snort.

"Brother Li, are you okay?"

Looking at Li Mu, who was pale, the third master on the side couldn't help but shout.

"Little San, don't worry, wait a little longer!"

The old lady's eyebrows frowned slightly, obviously quite anxious about what happened to Li Mu.

"What the hell is on this stone wall, and why do I feel so much pain!"

Li Mu controlled his soul power and searched the passage on the stone wall inch by inch, but in his mind, he communicated with the silver mirror.

"This stone wall connects the two spaces, so there is too much energy turbulence on it, although there is no feeling when you touch it with your hand, but the soul power comes from your Mud Pill Palace, do you say there will be a feeling!"

Yinjing rolled his eyes, for example, the palm of his hand and the skin on his face, can it be the same thick?

Li Mu ignored the implication in the tone of the silver mirror, perhaps he had long been accustomed to this kind of silver mirror, and as time passed, Li Mu's soul power had gradually become accustomed to those stings.

"It's been an hour, why hasn't this Brother Li reacted yet!"

The third master glanced at the entrance of the cave anxiously, in another hour, the sky will be bright, but Li Mu has not reacted yet, but looking at his face, it seems that it is not as pale as just now.

"What's the hurry, we've been waiting for hundreds of years, are you still afraid of these last few hours?"

The old lady looked at Li Mu with an indifferent face, there were too many surprises that this young man brought him, and listening to what he said, it seemed that he wanted to join the hidden world, if he could really go out, he must talk to Long Guang, and he would definitely pull this Li Mu to the Shenlong clan, and it was also a matter of interest for the Shenlong clan to have such a genius.

Hula!

But at that moment, a sudden sound came from the wall, and then the sound grew louder and louder, and finally it turned into a loud roar......
