As night fell, four figures hunched over, taking advantage of the deep grass, slowly advanced towards the grove in front of them. The light in the grove is very weak, and the light that can be seen is shining from the house, and the distance that the guards can see is very short, and the more this happens, the better it is for stealth.

The wolf dog's sense of smell is very sensitive, there is a cover of night, it can only cover its figure, and it can't hide the smell, and it is about seven or eight meters away from the grove, and the two wolf dogs barked in the direction of Han Wei and the four of them. The barking of the dog immediately caught the attention of the caretaker, and two flashlight rays could be seen shining in this direction. The other party was a little far away, and he didn't find anything, so he walked this way.

Han Wei, Li Hua and Liu Shi all stopped, lurking in the grass, not even daring to raise their heads, while Lin Xue continued to walk forward alone, and soon came to the side of the fence, the two barking dogs, wanted to rush out and bite her, but they were chained and couldn't take a step forward, otherwise Lin Xue would be torn to pieces.

Lin Xue just glanced at it, the two dogs immediately quieted down, and then turned around, Lin Xue hurriedly lay down, the whole person was hidden in the grass, it was very uncomfortable to lie in the grass, and the bare body was itchy, but he didn't dare to scratch it, for fear of being found and falling short. At this time, several guards came, and the two dogs suddenly began to bark wildly again, but they were biting each other, and the scene was very tragic, and one of them was bitten off half of his ear, and the blood did not stop.

"Okay, how are the two dogs crazy, pull them away."

"What should I do if I go up and get bitten a few bites, just let them call it, don't give me food at night, and it will stop if you don't have the strength."

"Keep yelling, nothing will happen, right?"

"What will happen? Hurry up, starve to death. ”

The sound of talking gradually faded away, the barking of the two dogs was still the same, and not far from them, Han Wei and the four of them had already climbed over the fence and sneaked into the grove. Originally, Lin Xue would return the same way as long as she controlled the dog, but she didn't leave like this, saying that she could lead others away later, and without waiting for Han Wei's consent, she entered the grove. With Lin Xue's help, it must be much better, Han Wei saw that she was in good shape, hesitated again and again, and didn't say anything more.

Quietly approaching the front of several prefabricated houses, you can see that the people inside are eating, there should have been nothing before, the vigilance is very low, and there is no one guarding the door. Vultures and the like were not found, where would they be? All four looked at the tin room, which was the most likely place. Bypassing the prefabricated house, head straight to the tin room in the middle, where the door is closed and the light can still be seen through the gaps.

There was no one guarding the door, so I easily got there, looked through the gap, saw no human figure, and carefully opened the door, trying not to make a loud noise. Now several dogs are barking wildly, and as long as it is not particularly loud, no one will notice the situation here. The door opened, Han Wei and the four of them flashed in one after another, and then closed the door, the movements of the four of them were very agile, especially Lin Xue's performance, which was really unexpected.

The light in the room is not very strong, only an ordinary light bulb, emitting a yellowish light, but this light is enough to see the situation inside, there is a big hole in the middle, it looks like an ancient city, Han Wei, Li Hua, Liu Shi have experienced too much, you can see at a glance that the ancient city in front of you is an antiquity, definitely not a new building.

I have never heard of it, there is an ancient city in the grassland, Ulanqab City is the northern minority Khitan, Jurchen, Tatar, Washuang, Mongolian living place one after another, these ethnic groups do not have the habit of building cities, and the cities built have a certain reputation, in the current location, have not heard of the existence of the city.

Perhaps it is because of the lack of knowledge, there are many things buried in the dust of history, and the fact that they are not recorded does not negate its existence. Han Wei and the four of them walked into the ancient city along the dug steps, and in the direction of the right, there was a hole with light inside, which should lead to the depths of the ancient city. Will the vultures and others be in there? This is highly likely.

After entering the entrance of the cave, the inside is still relatively spacious, more than three meters wide, more than two meters high, the ground is mud, but the two sides are made of stone masonry, all are huge stones, polished very smooth, and many murals are painted on it. Due to the age, the mural is almost invisible, and only some vague outlines can be seen, proving the existence of the mural.

It's not just a matter of age, the murals buried in the ground for many years, as soon as they see the air, they will be damaged, as long as they are not protected in time, they will soon disappear completely, just like the murals in the Dunhuang grottoes, which are completely preserved, only a very small part, and many historical mysteries have disappeared in the long river of time and will never be understood again. The disappearance of these brilliant and mysterious histories has to be said to be the loss and regret of human civilization, and the four of Han Wei looked at the murals in front of them, and they all had some sadness and regret.

Continuing to move forward, Liu Shi habitually walks in the front, which is his housekeeping skill. After walking about fifteen meters, the passage is divided into two, at a ninety-degree right angle, if the vulture comes in, which side will it go?

Carefully inspected the two passages, there are traces of people walking around for a long time, but the straight one, the traces are obviously newer, if the vulture and others really come in, it should be the passage on the right. In the ancient tombs, Han Wei and the others often encountered the situation of choosing one of the two, or even choosing one more than one, which is almost a necessary confusion for large ancient tombs, so once they recognize which one, they will not hesitate anymore and immediately go to the right passage.

The size of the passage, which did not decrease with the depth, walked about a dozen meters, and in front of it were four passages, which were difficult to distinguish from the size and shape. The four passages, on the first one on the left and the first one on the right, are clearly marked, and are circles drawn with a red marker. This circle mark must have been drawn by the people who excavated the ancient city, what does it mean? Are these two the only ones that are passageways, or are these two impassable?

Liu Shi had already checked the traces of the four passages, but the four passages in front of him were paved with stone bricks underground, which was different from the dirt road, and the traces could be seen, but he couldn't tell whether someone had just walked through them. I checked other places, and I didn't miss every detail, but I didn't find any more useful clues.

"Either the soldiers will be divided into two ways, choose one for the unmarked ones and one for the marked ones, and no matter what they find, they will return the same way after five minutes." Li Hua saw that there had been no result, and proposed to go on both sides, leaving little time for them, and the other party might come in at any time.

"It's too dangerous to split into two ways, and we don't have enough flashlights." Liu Shi didn't agree, he came in a hurry this time, and he didn't think that he would come to the underground ancient city, so there was only one flashlight, and the front passages were equipped with lights, so there was no need for flashlights, but the four passages in front of him were all pitch black, and it was difficult to move an inch without a flashlight.

Han Wei also did not approve of going separately, it was safer for the four of them to be together, and they were about to speak, when they heard footsteps coming from behind, and the sound of talking. Someone came in, and if they didn't leave, they would soon be discovered, and they didn't have time to think about it, and immediately entered the first passage on the left. Because he didn't dare to turn on the flashlight, he didn't go far, but he stopped after advancing five or six meters, where there was a small turn, close to the stone wall, and it was pitch black inside, as long as the other party didn't walk in, it was difficult to be found.

Listening to the sound, it was two people who came, stopped next to the entrance of the cave, and then the smell of smoke wafted in, and they actually smoked in it, you must know that the oxygen in it was thin, and there were some flammable and explosive substances in the air, so it was easy to have problems.

"Quickly extinguish the smoke, if the boss finds out, there will be no good fruit to eat."

"What are you afraid of, I don't know when I will come out. You say there's really treasure inside? ”

"Don't change the subject, put out the smoke quickly...... Why are you still on the ground, boss, and they came out and saw it. ”

"I said Brother Ping, why are you so daring...... Don't be angry, I'll pick it up......"

……

Outside, the two talked again, and then left, listening to the tone should be waiting for someone to come out, now it is certain that the vulture must be inside, but which way is the right one?

A few minutes after the two left, Han Wei and the four walked out of the passage, and Liu Shi looked at the other three passages and determined the passage on the far right, which was the direction where the vulture and the others were. When the two were talking just now, they mentioned that the cigarette butts were still on the ground, and the boss would see them when they came out, Liu Shi looked for them nearby, and found traces of cigarette ash in the rightmost passage about two meters away, if it wasn't for this passage, how could the boss see it when he came out? Is it obviously impossible to go out of your way to check the other passages?

The two people who came just now didn't expect that a casual movement would expose the traces of the vulture and others. Han Wei and the four of them immediately walked into the passage on the far right, there was only one flashlight, and they had to slow down to take care of the four people. In fact, the mobile phone of four people can be used as a flashlight, but it is not clear how far it is inside, and it may take a long time to use the flashlight, and now it can save a little electricity.

At this time, the passage is similar to the one that I walked before, except that it is much longer, I can't see any other changes, and the most worrying thing is that there is a fork in the road ahead, if there are four more, I really don't know how to choose.

After walking nearly fifty meters, this is calculated by counting the steps, and there are no traps encountered along the way, so you can keep moving forward at a constant speed, and it is not difficult to know how far you have walked. As worried, he had to face a choice, but there were only two passages, and both of them had stone doors, all of which were concealed, enough for a not very fat person to enter sideways.

There are also iron rings on the two stone doors, which are not traditional rectangular doors, but round, and look at the carvings on them, typical of non-Han style. Thinking that this is the grassland, it should be an ancient city of ethnic minorities, and it is normal to encounter things in the style of ethnic minorities.

I didn't study Shimen too much, this is not what Han Wei, Li Hua, and Liu Shi are good at, if it is Lao Zheng, I will definitely be able to see many useful things from it. Liu Shi tried to push the stone gate, but he couldn't push it, he increased his strength, but he still didn't move, Han Wei and Li Hua shot together, and the stone gate still didn't react at all, could it be that there was an organ control?
