My skills are all passive.

After leaving the secret realm, Hao Yun can return to the supernatural world.

Recruit a large number of people, go back to the secret realm, and conduct a comprehensive excavation of the ruins inside.

In this way, efficiency can be increased, but this method is also a last resort.

Until the last moment, Hao Yun did not want to leave the secret realm empty-handed.

As for Hao Yun's decision, Nan Nan did not have any objection, and then turned around and continued to search in the hall.

After Hao Yun's eyes fell on the stone statue in the center again, a bold idea suddenly appeared in his mind.

As we all know, such stone statues are generally good places to hide things.

What's more, such a broken place in front can produce such a high-value elixir, not to mention this more precious place.

If there are no treasures, it is indeed difficult to convince the public.

Since they did not find anything outside, it means that the protected hidden location is relatively hidden and has not been found by others.

Thinking of this, Hao Yun suddenly jumped into the air and jumped behind the stone statue to take a closer look.

After knocking with his hands, he found that there was indeed a vacuum sound under the stone statue, indicating that the ground should not be solid.

This discovery immediately made Hao Yun ecstatic, thinking that he finally had a new clue.

"Come here quickly, I found the location."

In addition to being happy, Hao Yun hurriedly shouted to Nan Nan who was still searching, then put the God-killing Gun behind his back, hugged the stone statue with both hands, and moved to the side.

The material of this stone statue must not be ordinary stone, so there is a feeling of being heavy. Even Hao Yun, with such a strong force, seemed particularly strenuous when holding the stone statue.

Of course, Hao Yun also understood that there should be a mechanism in this place, but he didn't know how long it would take to continue looking.

So Hao Yun finally took this method and decided to use force to move the stone statue directly, so that at least some time could be saved.

At this time, Nan Nan, who was far away, also ran over after hearing Hao Yun's shout.

"It's really heavy, but I finally found it." After taking great pains to move the stone statue away, a stone cave about one meter wide came into Hao Yun's sight.

This made Hao Yun very happy.

He couldn't help but mutter.

This stone cave is unfathomable, and there are no steps inside. I don't know what is underneath.

At this time, Nan Nan, who came over, suddenly took the initiative to suggest: "Let me go down and explore the way first?"

Hearing this, Hao Yun couldn't help but be stunned: "You want to take the initiative to go down, aren't you afraid of danger?"

No one can guarantee whether there is danger under this unfathomable stone cave, but Nan Nan actually took the initiative to propose to go down, which is really beyond Hao Yun's expectations.

After all, there is a great possibility that she will die directly after going down.

And Nan Nan is very clear about this truth, but she also knows that if she can't show her value, then once something happens, she may be abandoned by Hao Yun.

Once you leave this hall, you may be attacked by monsters outside, and finally there is no way to successfully reach the exit of the secret realm.

So even though she knew there was danger under the cave, she had to be the first to go down and show her value to Hao Yun.

Although this was a gamble, there was still a high probability that she could survive successfully.

At this time, Nan Nan did not give Hao Yun any chance to hesitate. After finding some ropes and other things in the hall and putting them together, she threw them into the cave and slid down along the rope.

"It's really interesting."

Seeing Nan Nan's quick movements, Hao Yun couldn't help but shook his head, and then made a torch with the candlelight in the hall and slid down along the rope.

After falling down for about a few dozen meters, Hao Yun finally stepped on the ground.

Under the light of the fire, he could see Nan Nan next to him.

"Are you okay?"

Perhaps because Nan Nan's movements were so quick just now, Hao Yun's favor increased, so Hao Yun took the initiative to care.

Nan Nan smiled and replied: "Don't worry, it's safe down there."

After confirming that Nan Nan was not injured and there was no danger around, Hao Yun walked in front holding a torch and continued to move forward along the passage.

After careful observation, Hao Yun found that the stone wall of this passage should be made of a special material, which was very cold to the touch.

There was no way to predict the direction of the passage, which was similar to some kind of underground maze.

In this way, after advancing for nearly a thousand meters, the originally narrow passage suddenly became wider.

And a black and gold stone door appeared in front.

"It's sealed. What is inside? Let's find the mechanism first."

After sensing the stone door with his hand, Hao Yun found that the material of the stone door was harder than the strength, so he could only tell Nan Nan to look around to see if he could find some mechanisms to open the stone door.

In theory, the closed nature of this underground passage should have mechanisms in the stone door and nearby. As long as they can be found, they can open the stone door and continue to move forward.

Although Hao Yun didn't know what was behind the stone gate, he had to give it a try in order to find new clues.

Perhaps there will be new clues behind this stone door, which may change the current predicament.

Nan Nan had no complaints about Hao Yun's instructions, and then he touched the stone wall with both hands, trying to see if he could find any clues or mechanisms.

As for Hao Yun, he also released all his perception abilities and used them on the stone wall to find the mechanisms in the stone wall.

I don't know if it's because the stone wall has a kind of blocking effect on telekinesis, so Hao Yun's perception ability can only act on the surface, and there is no way to go deep inside, so it can't play any role.

In this way, the two of them searched for twenty minutes, but still found nothing, and Hao Yun's patience was gradually exhausted.

Intend to use violent methods to see if it can be cracked.

"Push back first."

After letting Nan Nan retreat a few steps and make a safe distance, Hao Yun directly punched the stone door.

And he also used his own critical hit.

The embarrassing thing is that after this punch, the entire stone door and the passage did not move at all, without any damage, as if all the power was absorbed and dissolved by the stone door.

This made Hao Yun quite surprised, and he couldn't help but sigh: "How could this happen?"

"What is the material of this stone door?"
