The group hurried to the sand dunes in front, Lin Song ordered Zhang Feiyu and Wu Meng to stay on the sand dunes as reserves, and Lin Song took the snow wolf to the side of the sand dunes, under the cover of the dark night, and came below.

The ruins of the ancient city of the Yue Clan had been submerged in a sea of sand before, and Lin Song only discovered it when he came to the ruins. Those tomb robbers used ** to blow up a dome-like structure, allowing the sand on it to leak in. From the ground, it looks like a bottomless pit sleeping between the crevices of the dunes. It was like an eye, peering into the sky above.

And next to this 'bottomless pit', there is a towering wall, Lin Song guessed that this place should be the city wall of the ancient city of the Yue Clan.

Before setting off, Lin Song had browsed some documents about the ancient city of Yueshi. Lin Song knew that the height of the walls of the ancient city of the Yue clan was much higher than that of the Central Plains.

According to the regulations of the Chinese year, the length and height of the city walls of the national capital, state and county capitals and other places have corresponding regulations. In addition to being easy to manage and build, this is also the importance of 'etiquette' in the Central Plains culture.

Legend has it that the ancient city of Yueshi was the largest city in the world at that time, and its specifications were even close to the size of the Han Chang'an City. You must know that outside the vast and sparsely populated country, many countries may not build such a city with the strength of one country.

Moreover, the walls of the ancient city of Yueshi have a very interesting feature. That is, the city wall of the ancient city of Yueshi was not only built as a military fortress, but also opened up a lot of horse paths, lanes and other places above the city wall, and on both sides of the horse road lane, there were rooms to use as private houses!

In other words, the walls themselves are part of the homes of the inhabitants of the city! Moreover, the city wall was divided into many layers, and below the top dwellings, it was the place where the garrison stayed.

This design is said to be due to the fact that the trade in the Western Regions was prosperous and the space in the city was limited, so many foreign merchants and travelers lived on the city wall.

Thinking of this, Lin Song hurriedly said to Wu Meng: "If this is really the city wall of the ancient city of the Yue Clan, then this city wall should be empty, and there is a place to climb up from the side." ”

"You mean, we're going to climb up now?" Wu Meng said: "Shouldn't we just deal with those guys below?" ”

"What's the hurry, it's too difficult to get close to them silently in the open area, and looking at their appearance, they should be probing the surrounding terrain now. We'll go up first, and it won't be long before they'll have to follow. Lin Song said.

Wu Meng nodded: "I understand, you mean, let's go up first and prepare the encirclement and ambush!" ”

"That's right, that's what I meant." Lin Song said directly.

After making up his mind, Lin Song took the lead and let the snow wolf explore the way in front, and the two comrades-in-arms in the back followed, everyone looked forward little by little along Sha Qiang, and suddenly, they heard Wu Meng say: "Boss, look at this!" ”

Lin Song hurriedly turned around, and saw that there seemed to be something under the sand wall. It looks like a vine.

"In this kind of place, there can't be vines, such a long strip is not broken, then it can only be ......" Lin Song said as he blew a breath, and suddenly revealed an iron chain that was still shining with cold light.

"Sure enough, this is it!" Lin Song said: "Follow the chain and climb up." ”

At this moment, the wind and sand rose again, and the sound of the iron chain being dragged was blocked by the wind and sand, and Lin Song and the others climbed up very smoothly. Just about ten meters away from the root of the wall, Lin Song found that a hole appeared on the sand wall.

Lin Song dragged a few comrades to climb in, and Wu Meng couldn't help but ask, "The ancient city of the Yue Clan has disappeared for thousands of years, why is the iron chain still the same as new." ’

"The ancient city of Yueshi is buried underground, and the oxygen content in the sand is very low, and it is extremely dry, and it is almost impossible for the iron chain to be oxidized." Lin Song said: "And the smelting technology of the Yueshi was quite clever back then, I think there may be other ingredients in this iron chain to prevent oxidation and rust." Okay, let's not talk about that, they seem to be here! ”

Everyone hurriedly listened, and sure enough, they heard footsteps from below.

"I've heard rumors a long time ago that inside the walls of the ancient city of the Yue Clan, there is a pedestrian passage that leads directly to the bottom. Most of them just used the detector to find the entrance to the passage. Lin Song said: "Ready to do it." ”

Everyone nodded, and hurriedly dispersed, and after about ten minutes, they heard the footsteps below getting closer and closer.

Lin Song raised his arms, shook his fists, and signaled everyone not to worry about it first, and wait for all the other parties to come up.

Finally, the people hiding in the corner saw a figure come up, and after taking two steps, they nodded to the people behind: "Come up." ”

Immediately afterwards, four or five more people rushed in, and these people walked into the corridor inside the city wall, and Lin Song followed the light of the flashlight in their hands and saw these people clearly.

It's all foreigners, and these guys really aren't from the archaeological team! Lin Song saw these guys walking forward slowly, as if looking for something.

"Do it!" Lin Song shouted, rushed out of the corner directly, grabbed one of the members of the other party who fell behind, and hammered it with his fist behind his ear.

The guy fell directly to the ground, the person in front reacted and hurriedly turned around, Lin Song saw clearly, these guys were all armed with firearms!

Their action of pulling out their guns was also seen by Wu Meng, who unceremoniously pulled the trigger in another direction, and three people fell down in an instant.

There was only one person left, running towards the hole on the side, and was about to pass through the doorway, when suddenly an arm stretched out from the side and stuck it his throat, and with a bang, the man also fell to the ground.

"Three...... Four...... Five, no! There are only five people, and they should be six people, right! Lin Song said.

At this time, there was a rush of footsteps below, no, he was going to escape!

Lin Song hurriedly rushed up, but at this time, the snow wolf actually rushed out of the city wall directly, and after sliding down for a distance along the outer wall of nearly ninety degrees, he rushed back directly, and a miserable scream came from below. Lin Song and the others hurriedly ran down, and saw that the man had fallen to the ground unconscious.
