"Let's go!" Seeing Song Yun's face was gloomy and gloomy, Mr. Li was afraid that Song Yun would regret it, so he took Song Yun's hand and walked into the depths of the cave.

Song Yun thought for a while and it was only one hundred meters, so nothing happened, so he felt relieved, took a few steps, walked to Li Shishi, and then took out the mobile phone with a strong flashlight from his pocket and turned on the flashlight.

The light of the flashlight was still very powerful. After walking about twenty meters, it became obvious that it became dark around. Song Yun suddenly stopped and took out a bundle of thin ropes from his pocket.

"What is this for?" Li Shishi asked curiously.

"It's for life-saving at critical moments." Song Yun pulled a thin rope away, then tied it to a huge stone pillar, then tied one end of the rope around his waist, and said, "Okay, let's go."

"Wow, it looks so professional, but Song Yun, is this thing reliable?" Li Shishi pulled the rope and asked.

"We will not break if we hang it up. This is a professional utensil." Song Yun said proudly, continuing to walk deep into the cave.

The opening of this cave is very large, but after walking inside, the road inside is very narrow, and it tends to be getting narrower and narrower. After walking about fifty meters, the road is so small that it is only enough for two people to line up side by side.

"It's about fifty meters, and there's no mechanism and nothing. If there's another fifty meters, let's go back." Song Yun said, turning over a corner in front of him. After turning over this corner, a huge pit suddenly appeared in front of him. The entire pit was so big that Song Yun couldn't even guess how big it was. The main reason was that Song Yun had a flashlight in his hand and there were no other light sources.

"It seems that there is nothing to see." Song Yun said, holding Li Shishi's hand.

"Oh, it's a pity that people thought they would have some treasure or adventure." Li Shishi said depressedly, walked forward a few steps, walked into the pit, and Song Yun followed behind him.

"Wow, it's really big!" Li Shishi followed the light of Song Yun's flashlight and looked at the top of the pit. It was about ten meters high, which was very rare in a cave.

The top of the pit is a naturally formed stalactite, and about one hundred meters ahead of the pit are several small holes, and no one knows where these small holes can lead to.

"If this place is developed, it will be really good!" Song Yun looked at the stalactites. The history of this cave must have been very long, otherwise there would not be such a long stalactite.

"Yeah, look at the sand here!" Li Shishi squatted down, grabbed it on the ground, and then handed his hand to Song Yun.

"Sand?" Song Yun was stunned. Logically speaking, there was no sand in such a pit, either stone or soil. Where did the sand come from?

At this moment, a rumbling sound suddenly came from not far away, as if it was thunder. Li Shishi said in surprise, "Whether it rains in winter?"

"My grass!" Song Yun's face turned over, and he finally understood why there was sand in this place!

"Damn it's an underground river!" Song Yun shouted, rushed to Li Shishi a few steps and picked Li Shishi up in the waist. However, the thunderous rumbling sound was still far away a second ago, but after a second, it had already echoed in the entire pit.

"You're cheating!" Song Yun looked helplessly at the huge torrent less than ten meters in front of him, and directly hugged Li Shishi tightly in his arms, then turned around and turned his back towards the torrent. Accompanied by Li Shishi's screams, Song Yun and Li Shishi were directly swept away by this huge torrent.

In less than half a minute, the torrent retreated, and the pit returned to what Song Yun had just come, but Song Yun and Li Shishi had disappeared.

Turn your sight to the second peak.

Near the peak, Zhou Guang and others also stopped because a cave also appeared in front of them.

Outside this cave, it looked much smaller than that of Song Yun's cave. Yamamoto Izuki took the map and looked carefully, then looked at the cave again, and shouted in surprise, "It's just this place!"

"Then let's go in." The Ghost King took the lead in walking in the front, but the God's Pursuit shouted, "Wait a minute."

"What?" the Ghost King asked dissatisfiedly.

"No one knows what the situation is in the cave. The preservation work must be done well!" The God's Psychic said, taking out some bottles and jars from his bag, including oxygen bottles, safety helmets, etc. Anyway, all kinds of tools are available.

After the group of people armed themselves, they walked into the cave together.

"There are many branches in this cave. Remember to follow me when the time comes!" Yamamoto Isaka instructed, "And, it's raining heavily now, so be careful of the underground river."

"I know." Zhou Guang nodded, and didn't want to cause any trouble at this time, so he followed obediently.

Because of the instructions from the map, the group and others walked very fast in the cave. Occasionally, they encountered some forks and other roads, and followed Yamamoto Izuki's instructions. After walking for about half an hour, several people had already entered a very deep place in the cave.

And at this time, in another place.

"Ahem."

In a dark cave, a cough suddenly sounded, followed by another cough.

One male voice, one female voice.

"Song Yun, where is this!" The female voice trembled slightly.

Then, a light suddenly lit up.

"This mobile phone is really good." Song Yun said with emotion with his hand, which was said to be waterproof when he bought it, then looked at Li Shishi and asked, "Are you hurt?"

"No, I just choked a few sips of water." Li Shishi coughed a few times and said, "Song Yun, look, where are we now."

"How do I know where?" Song Yun looked around. Not far ahead of him was a huge pool. According to what happened just now, he was probably washed here by the water flow from the underground river!

Song Yun couldn't help but be glad that his body was different from ordinary people. The violent water flow just now. If an ordinary person was hit directly, he would definitely faint. Although he was in pain, he did not faint after all, otherwise he would have drowned with Li Shishi.
