A few minutes later.

The third son has already returned, with an extra backpack on his body, and he doesn't know what to put in it.

"Master Cao, it's time to go."

Seeing Cao Qing's stunned appearance, the third son couldn't help but feel a little strange, stretched out his hand and patted him a few times before waking him up, and asked, "What's wrong with you?" ”

"Oh, it's okay, think of something to figure it out."

Cao Qing shook his head, but there was a hint of expectation in his eyes.

For everything Yan Jun said, in fact, he already believed most of it, and the only thing that needed to be verified was the so-called Yongguo.

As long as there is a clear written record in the ancient city, then all the speculations can be justified.

Although the third son was a little puzzled, Cao Qing said so, so he had to suppress the curiosity in his heart and walk to the front to lead the way for the two.

Soon, the three of them reached the exit of the cliff mountain road again.

"It's a fucking dead man's city."

Even if he was mentally prepared, when Cao Qing really saw the ruined ancient city under his feet and the dead people in the city, he was still shocked.

After robbing the tomb for so many years, the level of horror brought by this scene is definitely in the top three.

"Master Cao, look over there, the architectural style of this ancient city doesn't look like the cemetery we saw at the foot of General Mountain that time?" The third son pointed to the distance and discussed with Cao Qing.

What the General's Mountain Cemetery was, Yan Jun didn't know, he couldn't understand what they were talking about, so he simply carried the mining lamp and studied the cave.

There are no signs of tools cutting through the surrounding rock walls, more like a natural cave, but the trail they are on clearly shows signs of being hewn, and it is similar to this mountain road.

Yan Jun counted carefully, there were about seven or eight, extending from all directions, leading to the bottom, as if they were specially designed to facilitate passage.

On top of that, a spiraling downward plank path has been carved out of the cliff face, and several intersections are right on the edge of the plank road, and you can jump up the next step, enough to accommodate three or four people to pass side by side.

Looking at the plank road, Yan Jun seemed to have a scene hundreds of years ago in front of his eyes.

Countless mediocre people are busy day and night, carving a path to the outside world on the rock wall.

This scene is even more shocking than the ancient city in front of you.

"Be careful."

"Master Yan, what are you doing?"

Almost subconsciously, Yan Jun jumped directly from the rock protrusion without even thinking about it.

It's just that this sudden scene scared Cao Qing and Sanzi enough, and they thought that Yan Jun was corroded by evil qi and couldn't think about it.

It wasn't until he stood firmly below that the two of them breathed a sigh of relief, but a little fear could still be seen in their slightly pale faces.

It's not like they've never seen this kind of thing, and many guys with weak psychological tolerance often do some amazing things after being strongly stimulated.

And the two of them were talking patronizing just now, and they didn't realize the situation below.

"I'm fine, Uncle Cao, there is an ancient plank road below, which can lead directly to the ancient city below."

Yan Jun stepped on the plank road a few times, although it had been hundreds of years, there was still no damage to the plank road, and it could fully bear the weight of dozens of people, so he raised his head and said to Cao Qing and Sanzi above his head.

"Ancient plank road?"

Hearing Yan Jun say this, the two of them noticed his feet.

"Really, I said how to go down this hellish place."

"This plank road can't be specially built to lead to the outside world, right?"

Both of them are old rivers and lakes, and they guessed the purpose of the plank road at once, especially after walking on the plank road, looking at the road under their feet that was cut out on the cliff, they were even more shocked.

"It's all chiseled out with a chisel."

"I don't think it's going to be a few decades, and it's hard to complete such a big project, right?"

casually touched the uneven and scattered stones, Rao is the silent nature of the third son, and couldn't help but say with emotion.

Cao Qing shook his head and said, "It's hand-chiseled!" ”

"But do you see the scale of the ancient city below? I estimate that the population at the peak of that time was tens of thousands, or even less, and it would be difficult for me to chisel such a plank road for decades. ”

"I said, you two, now is not the time to discuss this, shouldn't we hurry down and take a look?"

Yan Jun on the side was stunned.

If people who don't know their identities hear the conversation between Cao Qing and Sanzi, they probably think that they are from some archaeological research institute.

Leave these things to those who do academia and research, okay?

"Master Cao, do you think this is an occupational disease?" The third son glanced sideways at Cao Qingle and said.

"Okay, hurry up, stop it, listen to Yan Ye, hurry down, there's not much time left for us."

Sanzi nodded, turned on the headlamp and walked to the front of the team, his expression was no longer as relaxed as just now, his eyes were sharp and fierce, staring at the surroundings deadly, not letting go of any trouble.

And he held a boning knife in his hand that he didn't know where to go, and there was a cold light on the blade, and no one dared to underestimate its sharpness.

This is the old rivers and lakes, and when it is time to do the right thing, he will never be careless.

Yan Jun walked in the middle of the team, and he didn't dare to relax at all, so he was responsible for looking left and right.

As for Cao Qing, he was the rear of the team, guarding against movement behind him.

Walking along the plank road, there was a slight sound of wind from time to time in the surrounding darkness.

If there is wind, it means that the cave must have figured it out to the outside world, which means that they don't have to worry about the poisonous mist and miasma that will accumulate after the corpse decomposes.

The third son who walked in the front always maintained a high level of tension, Yan Jun noticed that when he walked, his body would even bow slightly, his feet firmly grasped the ground, and the whole person was like a strong bow ready to attack, which could jump at any time when he encountered danger.

"No, it's weird!"

Suddenly, Miko's footsteps stopped abruptly, and his right hand was raised high, clenched into a fist.

Yan Jun and Cao Qing, who were already on the same string, saw this scene, and they all quickly stopped and quickly leaned together.

"What's wrong? Sanzi, did you find something? Cao Qing's face was solemn, and he asked in a low voice.

"Master Cao, have you noticed it, the wind around you is gone, this place is so quiet."

The third son didn't even look back, but Yan Jun could see the nervousness and confusion on his face through his side face.

As soon as he said this, Yan Jun and Cao Qing suddenly reacted, the surroundings were too quiet, and the wind that they could hear when they came down just now also disappeared.

On the dark plank road, only the breathing of the three of them could be heard obviously becoming a little rapid, but other than that, there was no sound around at all, and the silence was a little weird.

"It seems to be."

"What's going on, isn't this place a little too quiet?"

Darkness, burial chambers, silence.

If these three words are released separately, they are not too scary, but when put together, they will make people subconsciously associate some bad things.

Even old guys like Sanzi and Cao Qing are solemn at the moment.

"Gollum ——!"

Just when the atmosphere gradually became tense, suddenly, a fierce scream suddenly sounded.

It was like a ghost scream, sharp and scary, especially the scream that kept echoing in the empty cavern, just like ringing in the ears of the three of them.

Then there was a rapid click, the speed was amazing, one moment it was still a few meters away, and the next moment it seemed to run dozens of meters away.
