Zhang Yu and others were looking at the belly of the mountain and checking the surrounding stone walls. At this time, Chengjue said in a small voice: "This cave looks like it was dug by hand, but I don't know what kind of person can do such a huge project."

"Manual digging..." Zhang Yu pondered and glanced at the four holes on both sides. With his experience of often going down to various caves, he could naturally see that there were indeed traces of manual digging here.

Not only that, he soon discovered that the ground under his feet was not flat, with rut marks. After stepping on it, Zhang Yu was able to confirm that the rut marks under his feet were very hard. It would definitely not be left recently, but was fixed in such a few years.

Meng Xing'er walked to Zhang Yu and whispered: "Have you discovered anything?"

"This place is definitely not newly dug. It is hard to say when it was dug. But I think it is important to find Bao Jiayin and Leng Lingxue first," Zhang Yu said in a low voice.

"That's right." Meng Xing'er nodded.

Zhang Yu looked down at the compass in his hand. The pointer on the compass pointed to the right rear. This is normal. He had already found the location where Bao Jiayin was, but he could not find the entrance.

"Go from here." Zhang Yu pointed to the hole on the far right. Although he didn't know whether this choice was correct, he could only walk like this.

He took the lead in walking towards the rightmost entrance, and the others followed behind. After entering the cave, his eyes were dark again. Zhang Yu did not use fire to illuminate it, but just closed his eyes and felt everything around him with his heart. Ah Gou walked in front, like a pioneer in the way.

As several people walked forward, they could feel that the road under their feet was a downhill, but the slope was not large and belonged to a gentle slope. After walking for a while, Zhang Yu felt that the surrounding area suddenly became wider.

When he opened his eyes, he could not see anything because he could not feel any movement around him. Zhang Yu lit a fire talisman again and threw it into the air as a lighting.

With the light, everything around you can see clearly. Here is another mountain belly, which looks much larger than the previous one. There are five holes on the surrounding stone wall. In addition to this, you can actually see a wheelbarrow lying on the ground, three broken picks, and a disintegrated iron bed in the corner.

Zhang Yu immediately walked over and looked at the things in the corner. The others followed and looked down.

After only a few glances, Chengjue said, "The wheelbarrow and pickaxe are already rusty, and the same is true on the iron bed. With these rust alone, it can be roughly determined that these things can be at least five or six years old."

"That's right." Zhang Yu nodded, and then saw that there was a stone inside the wheelbarrow.

He bent down and reached out to grab his hand from the car. The stone was not big, with a metallic atmosphere, and the color was a little yellow.

After looking at it for a few seconds, Zhang Yu said: "This should be ore, maybe copper ore."

"Ore..." Chengjue, Meng Xing'er and others looked at the stone in Zhang Yu's hand.

"This place is done by artificially, and there is also ore. I guess someone was mining here a few years ago. Now it should be an abandoned mine." Zhang Yu said.

"What I said, how could it be so big..." Meng Xing'er muttered.

"No matter how big it is, we must find the person." Zhang Yu put the ore in his hand on the ground, then looked at the Bazi searching for the horoscope, then pointed to the hole at the far right and said, "Let's go, let's follow this path."

Agou was also smart. When he saw Zhang Yu pointing at the entrance of the cave, he walked to the entrance and sniffed it.

After Zhang Yu and others stepped forward, it slowly walked forward. Zhang Yu and his friends followed A Gou all the way along the cave. The cave extended very long this time, but from the direction, they were indeed heading towards the direction where Bao Jiayin was before. Not only that, Zhang Yu could also confirm that the road under his feet was slowly downhill and had a subtle curvature.

After walking for a while, Zhang Yu suddenly felt something hit his calves. He instantly confirmed that it was Ah Gou who hugged his legs.

How could Zhang Yu not understand? This must be because Agou had discovered something. Because he knew that there was danger here, he did not dare to yell, so he could only react like this. Zhang Yu immediately stopped and said in an extremely low voice: "Stop."

When the people behind heard his voice, they stopped quickly.

"Don't move for now, I'll go to the front and take a look." Zhang Yu said again in an extremely low voice.

"Yeah."...The others just responded softly with their nasal tone and did not speak.

Now Agou has put down Zhang Yu's legs. Zhang Yu slowly took a step forward, and Agou immediately walked forward slowly.

Each person and the dog walked very slowly, making almost no sound. The front was still pitch black, but not far away, Zhang Yu found that the surrounding area became spacious. Not only that, he even felt the breathing of someone in front of him.

Moreover, the breathing sound does not seem to belong to one person, but to two people.

As soon as he noticed someone's breathing, Zhang Yu immediately stopped and listened carefully. He could quickly hear that the two people's breathing was completely done with their noses, and it seemed quite uncomfortable.

Zhang Yu directly showed off the money sword, and the money sword shot out, and then turned into 108 copper coins, surrounding the place where he breathed in front. Because his eyes couldn't see it, Zhang Yu could not say that he could hurt people directly, at least he had to ask why.

In addition, in this place, Zhang Yu could only feel the existence of these two breathing sounds, and there seemed to be no other movement around him.

He then lit a fire talisman and threw it into the air. With a "puff" sound, the fire light ignited, and he could see everything here clearly. Although it was a bit rash to ignite the fire, he was confident that if the people here dared to shout, he would be able to make the other party speechless as soon as possible.

However, when he saw the person in front of him, he was stunned and couldn't help but exclaim, "Ling Xue!"

At this moment, there were two people in front of Zhang Yu. The two people were obviously back to back together, wrapped in a large quilt, tied with a rope. The person opposite Zhang Yu was Leng Lingxue, with thick tape wrapped around Leng Lingxue's mouth.

The fire lit up, and Leng Lingxue also saw Zhang Yu opposite her. Her mouth was sealed with tape and she couldn't speak. Instead, she made a quick sound from her mouth, "Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

Zhang Yu snatched it up in two steps and quickly reached out to tear the tape on Leng Lingxue's mouth. Good guy, this tape can have six or seven layers if wrapped around it. Zhang Yu was worried that he would hurt Leng Lingxue's face with other means, so he could only tear off the tape layer by layer.

Just as he teased the tape, a "whimper" sounded behind Leng Lingxue.
