Haoyu reminds everyone to be careful, no matter what, to ensure life and safety first.

After a break of ten minutes, the group continued to walk towards the second floor of the entire building - until I reached the inside of the building, I realized that it was wider than it looked from the outside, and the inside was crisscrossed by a series of quilts, and I didn't know what it was designed for.

When I climbed the stone steps on the second floor, Haoyu in front of me suddenly stopped again, and at this moment, my attention was on him.

"What did you see again, Brother Haoyu?" I hurriedly asked.

"Director Hu, something may have happened to them!" With that, Haoyu dodged half of his body, and then I saw a bloody scene,—— there was half a human leg on the ground.

This leg was torn from a point of five or six centimeters slightly up the knee, and it was torn off by force, looking at the unevenness of the tear, and there was a large pool of blood around it.

Everyone was on the alert again, and they tacitly worked in groups of three or four, pointing their guns at different positions.

And yet there was nothing around.

Haoyu gently walked to the side of the broken leg and squatted down.

"It was preliminarily concluded that this was a male leg, and judging by the degree of skin aging, it should be between twenty-five and thirty-five years in age......"

Speaking of this, Haoyu paused.

I guess what he thinks: if the deceased is between twenty-five and thirty-five, it should be ruled out that it is Director Hu.

This is probably a blessing in misfortune - it's not that other people's lives are not valuable, but if someone has to die, then it's better not to be Director Hu, because his role is greater.

Haoyu paused for a moment and continued to analyze.

"The transverse surface of the broken leg is uneven, as if it was torn by some beast."

At this point, he paused again.

My mind fluttered.

When it comes to beasts that can eat people, I think most people must first think of tigers, lions, and then wolves and leopards, as for such an underground ancient city that has been closed for thousands of years, there should be no fierce animals on the ground such as tigers and lions.

Generally speaking, animals that can burrow into the soil are small, such as marmots, moles, rats and other books, or smaller reptiles such as lizards and snakes.

The thought of snakes makes me feel a thrill.

If it's a snake, it all seems to make sense, I've seen huge snakes a few times before.

"Could it be a snake?" Thinking of this, I blurted out.

"Snake!"

Haoyu's brows were also twisted.

"If it's a snake, this snake ...... How big does this snake have to be? ”

After hesitating for a moment, I didn't tell me about my previous experience of seeing the big snake, for fear that they would be afraid.

Haoyu asked his two subordinates to cover the stump with a white cloth, and at the same time told everyone again that they must pay full attention to the movements around them.

Keep going up.

The stone steps under his feet were mottled and full of cracks, and there were a few more bloody footprints in the upper footprints.

Everyone was holding guns, especially Haoyu at the front, and it could be seen that his whole nerves were tense.

Fortunately, all the way to the second floor, there were no more accidents.

When he reached the second floor, he had just taken a few steps when Haoyu stopped again.

I subconsciously looked at the ground where he was alive, but this time there was nothing.

"Brother Haoyu ......"

I just asked him softly.

"Don't you think the building we're in at this time is very strange?" Haoyu turned around, scratched his head and asked us.

"What do you think of?" Lao Kong asked him rhetorically.

"I thought it was strange to get into the building...... I always feel that the layout of this building is a little ...... But I just couldn't remember...... I feel as if the pattern of some large ancient tombs in the former Qin Dynasty is just much larger than that of ancient tombs. ”

"Tombs?"

Several people in the crowd exclaimed almost at the same time.

"It shouldn't be! This is obviously a castle, how can it be an ancient tomb? Lao Kong also shook his head, expressing disbelief.

Haoyu replied: "Of course, this is just my feeling - ten years ago, I once cracked a huge cross-provincial tomb robbery case, when the tomb robbery gang hid in the ancient tomb in order to escape for their lives, and there was no way, so we followed in......"

"Brother Haoyu, the ancient tombs in my country are all underground, but this building is built on the ground, like a castle...... How could it be an ancient tomb? Besides, I didn't find a coffin or anything like that. ”

Haoyu smiled bitterly: "Aren't the pyramids of Egypt built on the ground?" Actually, I just thought about this, and casually said this, I don't know much about this, and it's best that we can find a few old professors as soon as possible, maybe they can help us solve our doubts. ”

Continue to walk along the footprints on the ground, about a hundred and fifty meters, only to see the footprints enter the back of a door.

This is a room.

The door is of stone, and if you look closely at the ground, there are traces of rubbing.

Everyone was happy, and Haoyu waved his hand to ask everyone not to make a move.

The stone door is blue-brown and consists of two halves of stone slabs, and the door is tightly seamed.

Haoyu took out a Swiss Army knife and tried to reach into the gap between the stone door and the door frame, but after several attempts, he didn't get in.

Haoyu gasped.

"It's so tight!"

Lao Kong behind him also said: "With such a high level of construction, I am afraid that for today, ordinary construction companies can't do it." ”

Haoyu waved his hand again, motioning for everyone to take a few steps back, and after we took a few steps back, he put his left face on the stone door and listened a few times, then retracted his face and knocked lightly a few times.

"Director Hu—are you inside?"
