The final destination was a rather ordinary-looking ranch, and of course, now the rancher has been relocated elsewhere. The entire ranch has been completely isolated. Although he felt that something was wrong, Xing Jie couldn't say anything. After all, there is so much that is being excavated now that the world cannot be known.

The whole grassland can be said to be flat and vast.

It's just a place that is being cared for, but it's a hill that looks very ordinary.

The people of the 925 and reserve battalions are in charge of guarding here, and everyone who enters, no matter what their identity, must verify their identity many times.

As for the personnel sent by the Eighth Division, it is not only because of the shortage of manpower, but also because the three major organizations have just begun to accurately divide labor, with the Eighth Division mainly responsible for foreign countries, while the 925 and Reserve Battalions have taken care of the country. Of course, mutual assistance between each other is still necessary, otherwise the whole market has more wolves and less meat, and it is really not enough.

This point has been implemented very tacitly as early as three years ago.

The eight places sent a few people over, mainly to show their existence.

"Is this a tomb?" Xing Jie said in surprise as he looked at the hill there.

In Chinese history, except for the Tang Dynasty, which would open a mountain as a tomb, other dynasties basically looked for a place with excellent feng shui to use as an imperial tomb.

For example, Qin Yingzheng built his tomb in Lishan, and then the emperors of the Han Dynasty built it in Bailuyuan. As for the matter of building the Imperial Mausoleum, I haven't heard much that the grassland herdsmen have done this.

After Xing Jie crossed the cordon, he saw the dug gate at the bottom of the hill at a glance.

"It's not a tomb, it's an underground palace, a very pure underground palace. Except for a sacrificial altar in the main hall, there are no gold or silver sacrificial vessels, which is unique in the sacrificial culture of various periods. An attaché from the Eighth Division said.

Xing Jie nodded and walked in directly.

The whole underground palace is not large, except for one main hall and two side halls. There is no other layout.

It can be said that it is concise to the extreme.

"When you came in, was there this bronze fragment on top of that altar?" Xing Jie asked with a frown.

"That's true, but there are many sacrifices in the side hall. However, they are all large quantities and are quite common pottery utensils. The attaché replied in a timely manner.

Pottery? Although this thing is very common, it is only here in the Xiongnu? And there are a lot of them?

Although Xing Jie felt that it was a little unusual, it was too late to think about these questions now. After putting on a set of body armor, he led a ten-person team led by a tiger and directly entered the black hole behind the altar.

"Tiger, since this time it is the main force of the reserve camp, why didn't you see Yang Ming's kid? This time it's their home field, there's no reason not to work, right?"

He and Dazhi went in first, but only one word came out, saying that it was too dangerous inside. And then there was no letter. ”

Xing Jie nodded, held the gun, and rushed forward in a hurry with the most standard fighting posture.

"Brother Jie, the sign is obvious, we are not on the wrong path. ”

"Damn, the designer of this dungeon is psychopathic. Who's going to build a kilometre-long underpass? Isn't it crazy?"

"Tiger, can you shut up? So far, it's ten kilometers away. However, judging by the meandering nature of the passage, it should have been an underground river. This is a big deal, and this amount of work is an unprecedented huge project even with modern technology. ”

Several people sat on the ground, tired and panting.

On the one hand, I was nervous, and on the other hand, I was angry. No one expected such a situation to happen.

Originally, I thought that there was a labyrinth under this hill, but I didn't expect it to be what others thought it was.

Nothing, nothing but dark passages, no traps, no enemies, nothing but distances that no one else could imagine.

After nearly ten kilometers of high-speed progress under high mental tension, everyone was exhausted.

Xing Jie was also angry and wanted to laugh. This is the first time this has happened in so many years. I scared myself, and I was scared of mental tension. If this gets out, your face will be lost.

What the hell is this Mao Dun doing for three generations?

You are nomads, horseback archery is your business, why can't you build this underground tunnel?

Is it enough to build this thing?

In history, although the three of their ancestors and grandchildren were not like each other, they were desperately stubborn in the Central Plains. Well, I can't help it. But you can see how good they really are from their respective opponents.

Tou Mandan Yu is against the First Emperor! How hard Yingzheng's wrist is, there is no longer verbose here, but what is the result? After fighting with Meng Tian for so many years, although he was chased like a rabbit, he still established the Xiongnu, and until the death of the First Emperor, this Mandan Yu still did not die!

As for Mao Dun, who is suffering from advanced obsessive-compulsive disorder, he is even more dicked, and he is facing the veteran rogue emperor Liu Bang! The two of them fought in the dark of Baishan Mountain. Well, in fact, Liu Bang was surrounded, let's say this to give him face. (Note 1)

As for Ji Man, and Emperor Wen of the Han Dynasty, that's right, it is Emperor Wen of the rule of Wenjing. The big one is also the head breaking the blood flow. Later, he summed up the 16-character policy of 'the enemy advances and I retreat, the enemy is stationed and disturbs me, the enemy is tired and I fight, and the enemy retreats and I pursue'.

But they are amazing, and they have not heard of how much they have achieved in infrastructure!

As for this tunnel, it is impossible for them to make it out at all! If nothing else, let's just say that it is waterproof, and after so many years, this tunnel is still extremely dry, without the slightest sign of water leakage. Forget about other places, but what kind of place is this? Wu Yannaoer! The Hetao Plain within the territory has the reputation of being plugged into the south of the Yangtze River.

What's more, Xing Jie had just roughly estimated that according to the path they had experienced, they had crossed at least two rivers! But even so, there was still not the slightest sign of water seepage and leakage! It was a miracle that they could do this thousands of years ago!

Then let's talk about the basic structure of this tunnel, which is two meters high and about three meters wide, all of which are paved with terracotta bricks two feet square. Xing Jie could know at a glance that the four corners of the tunnel could be kept at 90 degrees, and the horizontal and vertical would not exceed two degrees!

Such a standard is simply unimaginable.

It's not that they are underestimating the three of them, they can't build such a tunnel if they are tired. Don't say anything else, just talk about this clay brick, Xing Jie touched it hard and delicate, and it was sound to the touch, although it was not as good as the gold bricks laid in the Jinluan Palace, but compared with the Qin bricks, it was almost the same!

Where exactly does such a super-high-standard tunnel lead? Why is there still no sign of the end of the 10-kilometer journey? There is no trace of the rest except for the special sign in the reserve camp.

Xing Jie's mind kept thinking about what might happen.

I used to think that this steppe people lived and fought and killed, and there was nothing remarkable.

But now it seems that they are a little too simple.
