The two didn't say anything more, and quickly corrected Liu Can's dislocated left foot, which helped him up.

It is estimated that Liu Can has been running wildly, and at this moment he has no strength at all.

"Hey, I said that your kid is not a sports student at school?" He Qiang has always been angry that the two failed to run Liu Can.

"No, I'm a child in the mountains, and I've been wild in the mountains and forests since I was a child." Liu Can seemed to understand what he meant.

"No wonder we can't outrun you!" He Qiang was somewhat uneven.

"You came back and broke your foot?" Yu Fei asked.

"I ran in the cave for a long time, but a lot of mountain goods poured out in front of me, and there were poisonous snakes, so I had to run back, and when I came out, I didn't notice that there was a pit here, and I fell directly into it." Liu Can explained.

"How do you know that cave you found is an exit?" Yu Fei glanced at Liu Can sideways.

"You'll understand when you get there!" Liu Can said with a smile.

The cave that Liu Can said is actually not far away, only about 30 meters away from the location of the pit, because there is a huge stone standing in front of the cave entrance, and it is not easy to find the cave entrance if you are not careful.

The entrance to the cave was large enough for four or five people to walk side by side, and the ground was fairly flat, and there wasn't a lot of rubble, but it had been trampled on by the animals.

After the three of them entered, they walked for a few minutes, Yu Fei and He Qiang watched while walking, but they didn't see the reason for looking at it for a long time.

"Liu Can, how did you see that this was an exit?" Yu Fei frowned.

"Since the animal can come in from here, it must be connected to the outside!" Liu Can smiled.

"Nonsense!" He Qiang glared at him, "Do you still need to come here to see this?" Just say it and we'll get it! ”

"No, he should have found something else!" Yu Fei suddenly calmed down, he felt that Liu Can's words should have something else.

"This big brother is amazing!" Liu Can gave Yu Fei a thumbs up, and then squatted down.

"Look, what are these things?" Liu Can shone a flashlight on the ground and pointed to the position of the aperture with his finger.

Yu Fei and He Qiang hurriedly squatted down, looked closely, and found that there were some things on the ground that could reflect light, but these reflectors were extremely fine, and they would never be able to find it if they were not careful.

Because a large number of animals passed by, the ground that had been a thin layer of dust had been trampled on, and the tiny reflections were wrapped in dust.

Yu Fei stretched out his fingers and pressed them on several of the reflectors, sticking them to his fingers.

When he turned it over, he couldn't help but gasp: it turned out to be a few shiny pieces of metallic sand! And, as you can tell from its appearance, it's definitely not natural!

"Hold the grass, how can there be such a thing here?!" He Qiang immediately shouted. "Just look at the color and know it's artificial!"

"As far as I know, there is hardly any metal of such purity among the metals of nature, except for gold!" Liu Can smiled.

"You mean someone accidentally left it here?" He Qiang was still a little puzzled.

"If there is only one place, your argument would make perfect sense, but it is not!" Liu Can stood up with a smile and began to bend over and continue to walk forward. "You come with me to take a closer look."

Although he didn't understand what kind of medicine Liu Can was selling in this gourd, he was telling Yu Fei and the others what he said, and there was the following.

Sure enough, as Liu Can limped forward slowly, Yu Fei soon discovered that the metal sand was actually distributed in a strip-like area no more than five centimeters wide very regularly, extending inward along the tunnel.

"I've seen it, and the metal sand is being sprinkled all the way from the cave hall outside!" Liu Can straightened his waist, clapped his hands, and said with a smile: "This shows that someone has passed by here with these metal sands!" ”

"Yu Zhenxing wants to run a steel mill?!" He Qiang's brain was opened.

"I see what you mean!" Yu Fei already knew what Liu Can wanted to express. "This cave hall is so big, there are no references around, and if there is no one to lead the way, I don't know where to go!"

"What do you mean?" He Qiang was even more confused.

"If I'm guessing correctly, this metal sand should be used to guide the way!" Yu Fei said word by word.

"Clever!" Liu Can slapped his hands and smiled.

"Nima, why didn't I expect it, it's amazing!" He Qiang praised sincerely.

"But that alone doesn't tell you what you judged, does it?" Yu Fei glanced at Liu Can.

"I know what you're trying to say, what do you mean this could be the entrance to Yu Zhenxing's lab!" Liu Can smiled brightly.

Yu Fei nodded, and said in a deep voice: "If it's an entrance, doesn't that mean that those animals before are likely to be raised by Yu Zhenxing!" ”

"No, no, no, those animals are absolutely wild!" Liu Can raised his index finger and waved his hand: "Such a huge amount, not to mention how big the cage is to be built, if you want to raise it, I estimate that billionaires will be eaten poor!" ”

"And when the animals crawled over me just now, I smelled something that can only be found in the mountains and forests! Of course, you may not feel it. ”

"Also, before I ran back, I had actually gone far deeper, not only did there be a lot of forks in this tunnel, but also, a few hundred meters later, there was a scary space about the size of the cave hall outside!"

"No wonder they're using metal sand as a guide marker!" He Qiang sighed: "With such a complicated route and a frighteningly large space, if there is no sign to guide the way, I guess no one will be able to find Yu Zhenxing's hiding place!" If you don't get it right, even going back has become a big problem. ”

"No matter how complicated the route is, as the owner, Yu Zhenxing I don't think he needs a sign to guide the way, and this kind of sign is still so inconspicuous, if you give the animals back and forth twice, I don't think there will be anything left!" Yu Feihu was suspicious: "Yu Zhenxing will be so stupid? ”

"You're not an ordinary brain, you're a good one!" Liu Can suddenly smiled mysteriously: "Yes, this thing should be left by the inner ghosts in Yu Zhenxing's team!" ”

"Haha, the enemy of my enemy is my friend!" He Qiang laughed.

"Not necessarily!" Yu Fei glanced at him, and asked Liu Can again: "But this is not enough to show that this is the exit, right?" ”

"The exit must be the exit, but whether we can pass it or not is a matter of two words!" Liu Can said with a smile.

"No matter, if it's an exit, we might be able to go out, if not, let's go and notify the captain and come directly to arrest Yu Zhenxing!" He Qiang is an anxious person, and he will come as soon as he opens his mouth. "So, whether it's the exit or the entrance, it's necessary for us to go in and have a look."

At this time, if Xiao Ling was here, it would not be a matter at all, but for Yu Fei and the others, it was indeed the truth.

After thinking for a while, Yu Fei also agreed with He Qiang's opinion.

"What He Qiang said makes sense, and it is indeed necessary."

"Anyway, the two of you have weapons in your hands, and it's not easy for me to move now, so listen to you!" Liu Can looked a little helpless, and continued: "If it's really the entrance, we've already found the thing that leads the way anyway, so it's a big deal for us to go back the same way!" ”

"What are you waiting for, hurry up, the longer it drags on, the more difficult it will be for us to find the captain when we turn back!" He Qiang said.

Without saying anything more, the three of them walked along the metal sand on the ground all the way to the depths of the cave.

Because Liu Can's feet had just been corrected and reset, the speed of the three was relatively slow.

As Liu Can said, after more than an hour, they turned around and passed through at least four forks in the road, and finally came to another huge space.

Fortunately, the metal sand on the ground never disappeared, and the more they got later, because there was no trampling on the animals, the metal sand on the ground was easier to identify, and the speed of the three people increased.

After walking for about half an hour, they walked through the huge space and followed the metal sand to a cavern. Before he could take a few steps, Liu Can screamed that his feet hurt, saying that he couldn't bear it anymore and needed to rest and eat.

Perhaps from the beginning of entering the cave, the three of them have been in extreme mental tension, and after eating something, they actually fell asleep collectively. When they woke up again, they found that they had slept for more than eight hours.

This kind of thing was very unexpected for Fei and He Qiang, but Liu Can didn't take it seriously.

The matter has come to this point, and after further discussion, the three of them have no choice but to move on.

The only thing I have to be happy about is that Liu Can's foot injury is basically no big deal at the moment.

Half an hour later, He Qiang, who was walking in the front, suddenly stopped and shouted: "Hold the grass, this time I ran into a ghost, how can there be such a thing here?!" ”
