After a thud, the entire hole trembled. At the same time, Lin Song had already jumped off the cliff.

Lin Song didn't use force when he jumped, the body stayed in the air for a short time, like a meteor, he just thought about falling directly below, half a second before entering the water, Lin Song learned the movements of a diver, tightened his instep, and the whole person fell directly into the water.

Emerging from underwater, Lin Song heard his comrades calling for him, and soon, the snow wolf was the first to swim over. These days in the desert, the snow wolf has been a little unenergetic under the scorching heat. Now in the underground dark river, the snow wolf is like a resurrected dragon, and the dragon is alive.

The snow wolf grabbed Lin Song's collar and dragged Lin Song towards the shore. When they finally came to the shore, Zhang Feiyu and Wu Meng reached out and pulled Lin Song up.

Lin Song looked at the location of the entrance of the cave just now, and said in a low voice: "We can be regarded as blocking those guys on it now, but the question now is, how can we leave this ghost place by ourselves?" ”

Wu shook his head violently: "I fell blindfolded just now, don't look for me for this kind of brain-using thing." ”

Zhao Hu shook his head even more: "Don't look at me." ”

Only Zhang Feiyu frowned and looked at the surrounding environment, and then said in a low voice: "Here...... It doesn't seem to be a natural cave. ”

Lin Song nodded: "Someone finally found out." The embankment of this river is so neat that it is impossible for the bank formed by the impact of ordinary water to be so neat. ”

"Artificial? If it is artificial, who is here to make such a neat embankment? Were you a resident of the ancient city of the Moon Clan? Zhao Hu asked.

Lin Song nodded: "Very likely, you guys come over and have a look." ”

As he spoke, Lin Song walked to the side of the embankment, squatted down and touched it with his hand, and when he raised his hand, there was something blue-gray on his hand.

"I've heard before that the most popular building material used by the people of Yueshi Ancient City is bean soil. The so-called bean soil is actually steamed with beans, ground into powder, and mixed with sand.

The original reason was that the sand was too loose and not sticky enough, so bean noodles were added. As everyone knows, after adding bean noodles, it has become extremely hard and has become a very good building material.

This kind of bean soil, made into a rammed earth-like thing, after firing, it becomes what we see now, and what I have in my hand, if nothing else, is the oxide layer left on the surface of this bean clay brick after thousands of years. Lin Song said.

A few comrades-in-arms nodded and said, "In that case, it means that someone has been here before." No, no, no, no one has ever been here, this place was built by humans. ”

Speaking of this place, Wu Meng frowned, looking very puzzled: "Boss, if you say this, I can't figure it out." Since someone specially built this artificial river, and this artificial river channel still has water in it to this day. So the statement that the people of the ancient city of Yueshi migrated to other places because of drought and lack of water should not make sense, right? ”

Lin Song nodded: "That's right, this is also where I can't help." ”

"And ah, every nation, every country has its own history books. But I found that this ancient city of Yueshi seems to only exist in the descriptions of other countries, and it seems that I have never seen a history book written from the perspective of the native people of Yueshi ancient city. Zhang Feiyu frowned and said: "If it is true that all the residents of the ancient city of the Yue Clan have migrated away, why is there no record at all in history?" ”

"Forget it, we're trying to escape now, not studying history." Zhao Hu said: "Let's hurry up and find a way, let's leave this ghost place first." ’

Lin Song nodded: "Zhao Hu is right, let's find a way to leave this ghost place first." ”

With that, Lin Song asked the snow wolf to help find the exit and see if there was any other way to get everyone back to the ground safely. When the snow wolf was in the desert before, his ability was limited a lot, but now he is in good spirits, and he is searching the scene at the moment, and quickly searching in the dark.

After about half an hour or so, he heard a howl from the snow wolf in front, Lin Song hurriedly ran over, and saw the snow wolf rushing at a stone wall in front of him, snorting, as if he was saying something.

"You mean, this is the exit?" Lin Song asked.

Wu Meng cried with a sad face: "Did the snow wolf get sunburned in the past two days, is this the exit?" Such a thick stone wall, if you can get out here......"

Wu Meng said as he casually knocked on the stone wall with the handle of the pistol, who knows, after the stone wall was knocked, it immediately shattered and looked open, and a lot of debris scattered from it.

"Good guy, this thing is crunchy!" Wu Meng said.

Lin Song leaned in and smiled directly: "This is shale!" It looks very hard, but it has been weathered, as long as you hit it hard, it can be broken quickly, and the snow wolf should be aware that there is probably a big space behind the shale, which should be the exit. Let's do it together. ”

Everyone hurriedly started to knock on it with the hard objects around them, and those shales were really easily broken and scattered by everyone. After a short time, a pit more than half a meter deep was hammered out. Lin Song walked to the shale, put his ears on it and listened, then turned around and let everyone disperse.

After everyone dispersed, Lin Song himself took a few steps back, checked the firearm in his hand, and then raised the pistol and directly pulled the trigger.

The bullets hit the shale and burst out a lot of sparks, and the shale wall behind it collapsed with a bang, revealing an exit more than a meter high!

The exit appeared, and a gust of wind blew outside, and Lin Song was overjoyed: "It's through!" Be careful, go out of here one by one, and beware of the grave robbers. ”

Everyone hurriedly walked out of here, but when everyone came out, they were immediately stunned.

Behind the shale is the inner city of the ancient city of Yueshi! Standing here, you can see the streets and alleys of the ancient city of Yueshi clearly.

"This is a city!" Zhao Hu couldn't help but sigh.

Lin Song raised a finger and led everyone to the ground, and the snow wolf group officially stepped on the ground of the ancient city of the Yue Clan.

"No, this ancient city is really ...... It's so weird! Lin Song couldn't help but say.

Lin Song's words made the team members feel creepy for a while.
