"Let's go, let's go!" Seeing Song Yun's uncertain expression, Li Shishi, afraid that Song Yun might change his mind, grabbed his hand and pulled him deeper into the cave.
Song Yun thought for a moment; it was just a hundred meters. It probably wouldn't be dangerous, so he calmed down, hurried a few steps ahead of Li Shishi, then took out his cellphone equipped with a high-power flashlight from his pocket and turned it on.
The flashlight was quite powerful. After walking about twenty meters, the surroundings visibly darkened. Song Yun suddenly stopped, then dug into his jacket pocket and pulled out a bundle of thin rope.
"What is this for?" Li Shishi asked curiously.
"It's for saving our lives in critical moments," Song Yun explained as he unraveled the rope and tied it to a huge stone pillar. After securing one end around his waist, he said, "All set. Let's go."
"Wow, you look so professional! But, Song Yun, is this thing reliable?" Li Shishi tugged at the rope and asked.
