Lin Yang's body was placed in the interior of the building by us, and the fat man carried Xu Qing on his back, and we had no way to take a wounded person to the original road, so we had to go through the entire ancient city and go out from the city gate.

For the sake of convenience, we did not look for the stone gates opened on the ring building, because when we passed through the third ring building, we found that these stone gates were staggered from each other, and it would take at least a whole day to reach the city gate by the stone gate.

For thousands of years, the facades of these circular buildings may have been destroyed when they collapsed, or they collapsed due to natural causes, or we saw many gaps in the collapse.

The ring buildings are all complete rammed earth walls on the outside, and the inner side of the rammed earth wall is a defensive building, and the inner side is a circle of residential areas. In front of the residential area is the next road. In short, the outer side of the circular building is a tall rammed earth wall.

According to Xue Ning's speculation, a city as large as this could accommodate at least 200,000 people back then, and such a population base was already a densely populated city 14,500 years ago.

The closer he got to the center of the city, the wider the road between the ring buildings became, until almost an hour later, the fat man was exhausted after almost three rings because he not only had to climb the wall, but also had to carry Xu Qing on the side.

"Stop...... Stop for a moment, I'm getting tired and dying. The fat man gasped, and we leaned against the edge of a rammed earth wall.

I cleared the weeds on the ground and asked the fat man to put Xu Qing on the ground, and Xu Qing woke up in a coma all the way. After he was put on the ground by the fat man, I saw that his eyes were wide open and his lips moved slightly.

After a long time I realized that he was talking again, but in a very small voice, and I looked at the fat man and put my ear to his mouth.

"I ...... I'm dying...... Hurry up, this is not a place for the living. ”

When the fat man saw me like this, he leaned his head over, and he asked, "What do you say?" ”

My ears were still close to Xu Qing's mouth, and he kept repeating the words until his voice was too weak to be heard, and Xu Qing then passed out again.

I got up and responded to the fat man: "He said let's hurry up." ”

"I have to go quickly, but I really don't have the strength to do it, fat man." The fat man sat back down.

Xu Qing's eyes were closed again, and his snort was weak. I also see that the fat man is indeed a little tired, and Xu Qing has been carried by him all the way, so it is not good to urge him.

I had a good rest last night, and I didn't waste too much effort after walking so far in the morning, and I basically recovered after stopping for a while, and walked to the side of the building alone.

The building is still the kind of defensive building behind the rammed earth wall that we have seen between us, the degree of dilapidation in this building is very heavy, the roof is basically gone, the sun shines through the hole, and it is not dark inside, and you can roughly see the scene inside.

I stepped into the rotten wooden door frame, which was still very low, separated by wooden partitions into small rooms.

As soon as I entered, there was a wooden table in the room facing the door, one leg had been broken, and the table top was tilted to one side. There are some fragments of porcelain bowls and jars on the ground, which should have been originally placed on the table, because the table top collapsed and fell on the ground and shattered.

The shape of the bowl is not like the usual, the edge of the bowl is very high and deeply concave, if it is not a large mouth, it is more like a cup. There were still some black lumps on the inside of the broken bowl, and I didn't touch it.

Before I knew it, I had followed the passage close to the wall to the deepest part, and I saw a white foot bone at the entrance of the deepest room.

I already had a premonition of what was going to happen in that room, definitely like the bone-strewn room we'd seen before.

At this time, I was not the slightest afraid, and even a little wanted to go over and have a look. Passing through the room between us, I walked uncontrollably to the doorway of the room where a bony foot sticked out.

From this location, I can probably see the panoramic view of the room, there are no other windows in the room, because the outside room window has sunlight coming in, so it is not too dark inside.

As I stood in the doorway, I could feel a cool air blowing out of the room. I was blown by this gust of wind, and my body shivered unconsciously.

There was no other smell in the house, it was somewhat dry. The ground is supposed to be dirty, but slightly blackened, and I'm afraid it's most likely the result of the corpses decomposing.

After looking at it for a while, I noticed that the bones seemed to be a little different from what I had seen in the room before. I leaned into the room with half of my body, and the white bones in the room were piled up very high, about twenty or thirty bodies, most of them still had their heads tilted back, and some of the skeletons had fallen off, but a few of them were under my feet, which were obviously different from the others.

The white bones of those different appearances are basically leaning on the outermost side, and there are no traces of being cut on their limbs, and the most special thing is that their skulls are in different positions, but there is almost no difference in appearance. The white skull bears a blackened mark.

I crouched down to take a closer look, only to see that it was a cylindrical thing inserted into the skull. I looked at it probably metal, slightly black and rusty. It only took me a dozen seconds to realize what this thing was, it was an arrow stuck straight into the skull.

There was a big crack around the arrow inserted into the skull, and I couldn't see anything after looking at it for a long time, only a small part of the arrow was exposed, and the shaft of the arrow should have been rotten a long time ago, so I had the idea of getting the arrow down.

I stepped on one of the table legs outside, only to find that the table was completely decayed, and it didn't fall over because it still had three legs to support it. Looking around and ignoring anything else, he broke off a piece of wood from the wooden partition, which should have been specially treated and quite strong.

The arrow had been inserted into the skull more than half deep, and I wanted to knock it out, but after a few times there was no change at all, and in a fit of rage, a wooden board slapped on the skull, and the arrow actually fell into the skull cavity and fell out of the gaping mouth.

But the skeleton seemed to be decaying, and the skull cracked with a click as soon as the plank slapped down. A piece of debris fell to my feet, and I was so shocked that I almost didn't sit on the ground.

I felt a little ashamed, and quickly said a few words of apology. The arrow was inserted straight into the skull, and it took more than a thousand years to stick it in this corpse, and I did not dare to take it with my hands, so I found two thin branches and clamped them together like chopsticks.

I didn't dare to stay here any longer, and after the light wasn't enough for me to look at the arrow, I left the building.

I just looked at the arrow in the sunlight outside, and the appearance of the arrow made me a little different. It's twice as short as I thought it would be, and it's not like the triangular arrows you often see. It was a long cone, and there were four barbs on the cone that weren't too protruding, and I could probably tell it was a phlebotomy or something.

Because the arrow itself was already wrapped in rust, I used a wooden stick to remove the rust on the tail of the arrowhead, and then I found some artificial traces on the end of the arrow less than three or four centimeters, and I immediately realized that this was a word.

I didn't recognize this word for a long time, the crooked strokes were very simple, and there was no other discovery on the arrow, so I remembered Xue Ning and showed him maybe I could find something.

After returning to the resting position at that time, they were still leaning against the rammed earth wall, their eyes open, and Xu Qing was still unconscious.

"Where did you go?" The fat man asked when he saw me coming.

"Just spin around." I replied and handed the thing in my hand with a stick in front of Xue Ning, and Xue Ning came to his senses as soon as he saw it.

Before I could tell him where this arrow came from, he got it directly, and I saw Xue Ning holding it in his hand and looking at it carefully, so he didn't speak again.

"Where did you get this thing from?" Xue Ning looked very excited, although he was asking me, his eyes were still on the arrow in his hand.

"Found it in the room over there." I pointed in the direction I was coming from.

The fat man was originally there with his eyes closed to recuperate, but when he saw us talking here, Xue Ning still had something in his hand to study, so he came over.

Xue Ning gasped when he looked at it and said, "This thing is a crossbow arrow." ”

That's why this arrow is so small, it turns out that it is a crossbow arrow. Then I pointed out the word I found to Xue Ning.

Xue Ning just glanced at it and said the word: "This is the word "Xuan". ”

The fat man looked at the arrow that snatched Xue Ning's hand and looked at it for a while: "It is indeed a regular script of Xuanzi, and this form is still a Tang Kai." ”

After saying it for a while, the three of us were stunned for a while, still the same question, why did this thing appear here, if it was an ordinary arrow, it would be fine, but it was still engraved with the regular script of the Tang Dynasty, it would be weird.

"Could it be that the Tang Dynasty merchant brought it too?" The fat man said.

Xue Ning immediately shook his head: "This is absolutely impossible. His tone was resolute.

You must know that at that time, swords were legally owned by ordinary people, but this crossbow arrow would never appear in the hands of civilians, let alone in the hands of a merchant with a low status at that time.

There is a clear record in the Tang Dynasty that it is not allowed to make crossbows and armor without authorization, and bows and armor are not allowed to be made without authorization. This thing does not require training at all, and ordinary people can shoot at targets accurately with it.

Then the arrows of crossbow arrows appear here, it must be the army of the Tang Dynasty who came here. Xue Ning roughly talked about why he so decisively denied the fat man's remarks, which was roughly similar to what I thought, only in more detail.

"Do you still have a place where you picked this thing?" Xue Ning was even more excited, and he pressed it down and asked me.

I nodded, and he immediately stood up, and the fat man became interested, and together they pushed me, and told me to lead the way at once.
