Hei Niu panted and crawled back, looked at me and Gao Moli, and said with a few sighs of relief: "Damn, Xiao Gu and I crawled and found that you two were gone, and I thought that you were caught by a female ghost and went back to warm the bed, and I was trying to go back to rescue you, but I didn't expect that you two big men were hiding here and chatting, I wondered, what is there to talk about!" ”

Gao Moli shook his head slightly, signaling me not to tell Hei Niu about the conversation just now.

I didn't know what to do myself, and I didn't know how to talk to him.

I cleared my throat and said to the black bull, "Well, I didn't say hello and slowed down a few steps because I didn't think there was any danger in this black hole." ”

"It's one thing whether you're in danger or not, you two can't be unorganized. Next time I fall behind, I won't look for you at all. The black bull said, turning his sturdy body and continuing to crawl forward.

I didn't see Gu Yixin, and after inquiry, I learned that Gu Yixin's foot was accidentally sprained and was waiting for us at a fork.

With the black bull here, I naturally don't want to ask Gao Moli any more questions. But after some conversation just now, I felt that Gao Moli behind me was as mysterious as a mystery, and I couldn't help but want to look back at him.

The diameter of the black hole is only two meters wide, and it is a little suffocating to climb up, and at this moment, I feel like a ground rat shuttling through the ground, wandering through the narrow tunnel.

After climbing for five minutes, the black bull suddenly stopped and said in surprise: "Huh? Where did Xiao Gu go? ”

When I looked up, I saw that the black hole had a bifurcation, two channels of the same thickness, leading in two diametrically opposite directions, forming a "T" shape with the one we are in now.

The passages inside the meteorite are the same, winding and twisting, like a maze, if you accidentally go astray, you are likely to be trapped in a circle inside the meteorite, and it is difficult to get out again.

"Didn't you say she was left waiting?" I squeezed in front of the black bull, looked at the two holes and asked him anxiously.

"Of course I said, it seems that there is another undisciplined master. But this little girl has a broken foot, she shouldn't be able to go far, or let's look for it separately? The black bull said as he went to the black hole next to him.

I pulled him back and warned him that the black hole in this meteorite is unpredictable, and if we get separated again, even if we find Gu Yixin, we will have to go back and find another person.

"You wait, I'll take a look." Gao Moli said, and before we could answer, he flashed into the black hole beside me.

Gao Moli is quick to act and has strong adaptability, and he used to explore the way, but at this time, I felt strange when I looked at his back, and I had an indescribable feeling in my heart.

Seeing that Gao Mo was far away, Hei Niu sat on the ground and asked me in a low voice, "Old Su, what did you talk about with your little brother in the back just now?" ”

"Don't ask, I'll tell you when I figure it out."

"It's okay, but there is one thing to say first, since the black robe that the little brother Shun came out has already been given to us, you are not allowed to shout to return it to him. According to my estimate, this thing can almost be exchanged for a single-family villa in Ziyu Villa in Beijing! ”

It turned out that Hei Niu didn't notice Gao Moli's abnormalities at all, but he was full of thoughts about the black robe, for fear that I would insist on returning it to Gao Moli, so he gave advice again.

"Good. However, wait for the black robe to score and give him some money, if he needs it. ”

After all, I analyzed it with Hei Niu, and according to Yixin's personality, if it wasn't for the emergency, she would definitely not act without authorization. It must have been in the ten minutes or so that the black bull went back and forth, something happened that forced her to break her foot and continue to move forward.

I shouted a few times at the two holes, but there was no response, it seems that Gu Yixin has already walked far away, maybe she has already set off when Hei Niu just left. Thinking about it this way, if you want to catch up with her, you really have to race against time and seize the time. If there is a fork in the two black holes, then the chances of us converging are small.

Suddenly, the light flickered, and Gao Moli returned, "There is a mark in front, it seems that she left it." With that, he turned and walked back towards the black hole.

The black bull and I hurried after him, and after a few minutes of climbing, we found scratches on the wall of a hole around a corner, which were very shallow and messy, and were obviously carved in a hurry.

Hei Niu took down the tactical spotlight above my head, shone on those scratches and said, "I didn't expect Xiao Gu to be such a beautiful girl, and her handwriting was so sloppy, even I, a cursive expert, sighed to myself." This, this seems to be the word 'mouth'? Could it be that she said to wait for us at the exit? ”

The black bull pointed to the last word and asked me, I carefully distinguished, that word is indeed a bit like a mouth, but the first two words are not distinguishable.

"Look at it from a distance." Gao Moli reminded me, then turned the corner and walked forward.

I took a step back and looked at the symbols left by Gu Yixin again, and suddenly found that these traces on the wall were not Chinese characters, but English letters: USO.

USO is the abbreviation of "unidentified diving object", could it be that Gu Yixin found an unknown diving object? However, this is clearly a passage inside the meteorite, how can there be water?

Hei Niu said worriedly: "It's bad, that little girl has been trapped in the tunnel for a long time and has hallucinations." I've heard before that when people stay in cramped and depressed places for a long time, schizophrenia, their brains will come up with something that they think is real. Alas, if I had known that she was running around, I would not have left her there alone. ”

I told Hei Niu that Gu Yixin has often received militarized training since she was a child, and her psychological quality and physical fitness are stronger than ours, she will not collapse easily, and she must have encountered an emergency.

As he was talking, Gao Moli shook his wolf eyes at us from thirty meters away. The Black Bull and I immediately rushed over and found a transparent soft door blocking the entrance to the cave.

The soft door is like a crystal waterfall, isolating the icy pool from the black hole of meteorites.

I took a look through Gao Moli's wolf eyes, and ten meters away from the soft door was the rock wall of the mountain, and there was a black hole in the rock wall, which was like a giant beast with its mouth wide open, quietly waiting for its prey in a waterhole.
