From seeing it

Listening to the barking dogs outside, Sun Tao said anxiously, "No matter who built this, let's leave here first."

Zhou Kesheng hummed and said, "That's right, let's get out of here first."

Sun Tao said: "Then which direction to choose?"

Everyone entered through the blasted gap, and there were dark passages with no end in sight on both sides. No one knew where the two passages led, and which side to choose to leave became a difficult problem for everyone.

Zhou Kesheng took out the compass, looked at the direction above, pondered slightly, pointed to one of the directions, and said: "The passage here is eastward, we choose this one."

Xiao Ling understood Zhou Kesheng's intention in choosing the direction. They entered the sea this time along the direction from west to east. Now this passage is facing east and the other is west. Choosing the passage facing east is equivalent to continuing forward, and going west is equivalent to going forward. is the return direction.

Zhou Kesheng put away the compass, and everyone didn't say much. Sun Tao took the searchlight and led three or four team members to immediately walk forward in the direction indicated by Zhou Kesheng.

Qin Yang led a few team members, waited for the crowd to leave, and glanced at the group of barking pigs slowly gathering outside the gap, and then led the team to catch up with the team.

At the beginning, everyone was worried that the group of barking pigs would pass through the gap and catch up. They didn't want to rush along the huge passageway to the east for about one or two kilometers, but they could no longer hear the barking pigs. They seemed to give up. catch up.

After confirming that the barking pig hadn't caught up with them, the crowd let go. Zhou Kesheng told Sun Tao and the others who were in the lead to slow down, changing their pace from a fast walk to a slow walk.

The parasitism of the lighthouse ghost jellyfish caused everyone's vitality to be seriously depleted. They had just rested for a while, and they were attacked by barking pigs, and then fled all the way here. Everyone was exhausted. This passage has no end in sight, and no one knows how long it is. Zhou Kesheng saw that the faces of the crowd were exhausted, and many of them could no longer support themselves, so they could only stop and rest for a while.

Everyone sat down to rest on the spot, and Sun Tao, Qin Yang and others stood guard with guns on both sides, in case another beast suddenly appeared.

"Xiao Ling, thanks to you just now." Sun Tao looked at Xiao Ling with a hint of shame on his face.

He was on duty with Xiao Ling before, but he fell asleep when he didn't want to. If it wasn't for Xiao Ling's great skill, he was suddenly attacked by a barking pig and could have killed the barking pig. Think, is his dereliction of duty.

Xiao Ling smiled and said, "Brother Sun, why are you being polite, I am also part of the team, this is what I should do."

Wang Lei said: "This sea area is very strange, as if there is no distinction between day and night, and it does not exist on modern maps. It is not surprising that Shenao appeared before, and now this ancient alien species of barking pig appears. There may be other ancient strange beasts. What I am wondering now is who built this tunnel? I am afraid that the ancients did not have such abilities, but it seems impossible to say that modern people... "

This is also a difficult problem that puzzles everyone, and no one can tell the reason.

Li Zhibao nodded and said, "The material used to build this passage is also very strange. It is neither rock nor the building materials we are familiar with today."

Among the crowd, Hu Shengzhe was resting while taking out the pieces of debris he had picked up earlier. These were the wall materials scattered when Sun Tao blasted the wall with explosives. Gradually, a very strange look appeared on his face.

"Old Li, Lao Wang, these are the fragments of the wall that I picked up just now. Take a look, what kind of material are they?" It was given to Li Zhibao and Wang Lei.

Wang Lei smiled and said: "Why, have you discovered some rare rocks again? You are a geologist, let's see what kind of material this is. You are an expert. No one of us can compare to you. You want to test We ha."

Hu Shengzhe shook his head, his face was very ugly, and said: "This is not a rock, nor is it a building material, it is... a bone."

"Bone? What do you mean?" Wang Lei took a fragment and looked at it. He couldn't see what material it was made of, and looked up in astonishment.

Hu Shengzhe took a deep breath and said, "I mean, these...are bone fragments."

As he spoke, he stretched out his hands, made a gesture, and said, "It's very huge...the fragments of an incomparably huge bone."

This sentence stunned everyone. Sun Tao, Qin Yang and the others showed puzzled expressions, wondering if the tunnel was made by crushing the building with countless bones? How many bones are needed for this? I am afraid that Professor Hu will say such bizarre words because of his old eyesight.

However, Xiao Ling, Yu Tingting and others understood the meaning of Hu Shengzhe's words, and expressions of shock appeared on their faces.

Xiao Ling couldn't help but interjected: "Professor Hu, you mean this is an extremely huge bone? These fragments are bone fragments, so we...are we in a bone now?"

As soon as these words came out, everyone including Sun Tao and Qin Yang finally understood, and then they all opened their mouths wide, showing inexplicable shock.

Hu Shengzhe's face was ugly, and he nodded slowly: "I've studied it all my life, and I can't be wrong. These gray and white fragments are indeed fragments of broken bones, and the density of this kind of bone is very high, beyond imagination..."

He stood up while talking, stretched out his hand, knocked on the wall of one side of the passage, and said: "Sun Tao just blasted the wall, and the fragments were bone fragments. There is only one explanation, the so-called gray-white we saw before. The huge wall is actually a bone that is too big to imagine. We blasted a gap in this bone and drilled into this bone. This so-called tunnel is neither a masterpiece of the ancients nor a modern building. , but a... bone."

Everyone was silent, but took a deep breath instinctively.

After a while, Wang Lei murmured: "If this is really a bone...whose bone is it? What kind of creature can have such a huge bone? The road we walked here just now is one or two kilometers long. The length of a bone must be calculated in kilometers at least, so the length of this creature..."

Thinking about it this way, everyone shuddered. Hu Shengzhe is an expert in this field. If he recognized the fragments as bone fragments, he would definitely not go wrong. Make it unacceptable to everyone.

It is possible for such a huge creature to have such a huge bone.

The 100-meter-long giant tortoise that everyone saw before felt that it was so huge that it was beyond imagination. They were amazed that there really was such a giant tortoise in the world. Compared with the bones, the giant tortoise is just an ant, not worth mentioning at all.
