Everyone was stunned when they heard the voice.

This voice clearly belonged to Xiao Zhang!

But how could he be inside this stone pillar?

They are not there.
Zhang Weishan thought about it and looked at the position above his head.

Did he fall from above?
I rely on!

Old Wu had analyzed before that when they came back, the stone steps might disappear.

If they were more cautious, it might still be on top of everyone.

And now Xiao Zhang appeared in this stone pillar again.

That is likely to be when they accidentally fell down when they were looking for a mechanism on the top.

What about Lao Wang?
"It's me! It's us, is Old Wang with you?"

Zhang Weishan hurriedly shouted.

Old Wu on the side also shouted.

"Hey! Can you hear me? Is our old Wang here?"

"Please speak!"

There was silence from the stone pillar.

After a while, I heard Xiao Zhang shouting again.

"I don't know if you can hear it, but I hear your voice!"

"I'm not with Old Wang, he should be fine!"

"I'm stuck here myself!"

"Can you hear me? Answer me, please?"

Everyone was taken aback.

Could it be that this stone pillar is a one-way sound transmission, they can hear Xiao Zhang's words.

But Xiao Zhang couldn't hear them talking!
"Knock knock!"

Zhang Weishan said hurriedly.

Captain Qin directly took out the climbing pick, and knocked twice on the stone pillar.

After these two sounds, Xiao Zhang's excited voice really came from inside.

"Is it you? I heard it!"

"Why don't you talk?"

"I can hear the knocking!"

Captain Qin said.

"This is troublesome, he can only hear the knocking sound, but can't hear us talking!"

"How to do?"

Zhang Weishan also had a headache for a while.

There is no way.

This is the case with one-way sound transmission, he can hear the vibration of the stone pillar itself.

But the voice of speaking cannot be transmitted.

Xiao Zhang was still talking inside, but he couldn't hear everyone talking.

This is the worst.

Thinking about Zhang Weishan said.

"If it is blasted, how sure can it be that the entire stone pillar will not be blown down?"

Old Wu looked at Shi Zhu and said.

"If the fat man is very confident!"

"But I'm not so sure!"

"If you want to keep such a stone pillar from blowing up, you can only make a hole in it like a bird carving a tree!"

"Otherwise it will easily cause a collapse!"

Zhang Weishan said.

"Then leave it to you!"

"Captain Qin and I went to the other side to attract Xiao Zhang and lead him to the other side!"

"You as soon as possible!"

Old Wu nodded.

It's convenient to talk to smart people.

They don't need to explore whether there is any other way.

Because that's obviously not the case.

This stone pillar is a mechanism.

If there is a way other than explosives, it will allow you to enter the interior of this mechanism.

Wouldn't this mechanism have no meaning of existence?

Even where Xiao Zhang is, the agency may not be visible.

The mechanism inside this stone pillar may be hidden in the wall.

thought here.

Old Wu hurriedly took out the small hammer and began to strike piece by piece.

Sure enough, he soon found an empty space under one of the murals.

He broke the surface stone with it.

A fist-sized hole was exposed inside.

It's so deep that you can't see the deepest part.

But this small hole is enough.

He put the dynamite in it.

Then call everyone to avoid.

Captain Qin knocked on the stone pillar and led Xiao Zhang over there.

Old Wu's side detonated the explosives almost at the same time.

Just heard a loud "bang".

With the explosion of explosives.

The entire bronze bridge trembled.

Almost at the same time, the top of the stone pillar was blown open.

It's about the size of a washbasin.

Such a hole is actually not small.

But in front of this big stone pillar, it still looks very small.

The big stone pillar was quiet for a while.

Then a hand came out.

After a while, Xiao Zhang's head poked out from inside.

He covered his ears. Obviously, in such a confined space, the movement of the explosives was very loud.

His ears were bleeding.

In that unsuspecting situation, his ears could not avoid being severely injured.

Everyone saw him dragged out of the stone pillar.

He was covered in slime.

Moreover, there are many maze vines protruding from the stone pillar.

Fortunately, Captain Qin led people to block up the hole in time, so the vines did not crawl out.

After doing this, Xiao Zhang's hearing recovered somewhat.

Zhang Weishan fetched water and a towel, and wiped the mucus off his body.

Xiao Zhang seemed to be out of strength, and sat on the ground for a long time before opening his mouth.

"I really can't hear you talking!"

"Otherwise, if you detonate it, at least tell me in advance, my ears are almost useless!"

Zhang Weishan also said helplessly.

"You can be satisfied if you can come out, in this place, it is not easy to get you out!"

"What's the matter with you guys?"

"What about the old king?"

Old Wu and the others also looked at Xiao Zhang.

Wanted to know what happened.

Why is there only Xiao Zhang here, but no Lao Wang.

Where did Lao Wang go?

Xiao Zhang sighed and said.

"I do not know either!"

"Speaking of this matter, it is extremely complicated!"

After talking about Xiao Zhang, he told the matter again.

It turned out that after they were separated from the crowd, they had indeed found their way up.

And all the way back to the previous cave.

Then they found the drone and told the outside about finding the bronze door at the entrance of Yaoyang.

Let them spread the news as soon as possible, so as to attract Liu Feiying and others.

After doing this, they were going to come back overnight.

After all, spending the night in a cave full of vines is not a wise choice.

After they came down, they were going to come back overnight.

However, after searching for a long time, they couldn't find the stone steps that came down before.

They thought it was too tired, so they planned to rest for one night and look for it the next morning.

But after sleeping for a few hours, Old Wang woke him up by shaking him.

Say something is wrong with this place.

He just got up to pee to see.

The place where they rested is the place where they came down before.

But the stone steps were gone.

They can't go down at all.

The two shouted on the cliff for a long time, but no one responded to them at all.

In this way they have been trapped above for three or four days.

During the period, they even lowered all the ropes on their bodies, but the height was still not enough.

Then they heard the sound of the bronze door opening.

They knew that Zhang Weishan and the others might have progress.

But they couldn't go down, and there was nothing they could do.

Just when they were so anxious that they didn't know how to get in touch with Zhang Weishan and the others.

They suddenly found out.

A passage appeared on the wall that was originally a dead end.

The location of this wall is very special.

It's on the mountain above the bronze gate.

It was what they saw when they first found that platform.

On the gully where the bronze gate is located, there are two platforms on the mountain walls on both sides.

And this crack happened to lead to the interior of the mountain above the bronze gate.

Lao Wang said.

Anyway, this place leads to the top of the bronze gate. Maybe there is a passage in the mountain to connect to the bottom.

It's better to go in and try.

In this way, at least something can be done, so as not to be unable to use any strength in place.

So after the two discussed it, they got into the cracked passage.

The crack channel is narrow, but deep.

They walked for hours to get across.

What appeared in front of them turned out to be a space the size of a football field.
