The collapse in the depths of the cavern came without warning, and everyone fell immediately downwards as soon as their feet were empty. The glow of the searchlight vanished at once, and everyone was completely plunged into darkness.

Wu Yun is naturally no exception. He fell heavily on his back down. The only thing I was thankful for was that the ground was very soft. Before he could shout, countless clouds of sand and dust rushed to his face, and many small particles poured directly into his large mouth. The bitter feeling was like sand. But maybe it's a good expectation, after all, he has never tasted the sand, and naturally he can't tell the real taste of the sand.

"Help~~" The sharpest of them is naturally little Lori Wendy. She kept shouting, completely lacking the power of the thousands of horses just now. Although the others couldn't tell the difference, it could be heard from the cursing tone that everyone had suffered the same fate.

A small pillar of light lit up not far from him, and when he saw this ray of light appearing in the darkness, everyone's noisy voices disappeared at once.

"It's good that there's sand down there..." The fox's voice came from the light, and it was only then that Wu Yun could see that the source of the pillar of light was emitted by a flashlight.

"It's kind of weird... This sandy place... The pillar of light shone up and down, and the fox said in confusion, "Be careful, everyone, don't slide down." ”

At this time, Wu Yun found that the sand under him did have a large slope. Fortunately, the friction between the body and the sand can barely keep me from slipping.

"It's so dark here~" Wendy said with a little cry. Although she is very tsundere and can fight, there is no way to hide the fact that she is just a little girl. Just when everyone is helpless. A faint yellow light slowly emerged on the dark ground.

"Poof~" A square object with a soft glow came out of the sand not far away, and everyone was shocked. Wu Yun recognized it at once, this was the metal box that had been with Wendy all along. It had been silently following the back of the line since it entered the cave, so much so that Wu Yun had almost forgotten its existence.

"Vivien~" Wendy shouted excitedly, and the box popped out of the sand, and it slashed past Wu Yun, rushing not far behind him. A small figure pounced. The moment it received the little master, the surface of the box suddenly emitted a dazzling light, and it was like an artificial sun, which immediately illuminated the place where everyone was as bright as day.

Although everyone has been fighting in the cave for a long time, due to the limited strength of everyone's lighting equipment, no one has seen the whole picture of the cave, and now with the help of the metal box. Everyone was immediately fascinated by the scene in front of them. Everyone landed in a huge yellow sand pit, and Wu Yun immediately felt that he was on the edge of a huge sand funnel. The sand all around it flowed down at a very slow speed, and at the bottom of the pit was an eerie circular opening, about the size of the entrance to an anthill, and the reason why it was weird was because the vicinity of the cave gave people an extremely smooth feeling. At this time, Wu Yun discovered the subtle difference in this sandy area, the closer to the entrance of the cave, the finer the sand particles became. Is it naturally formed here or is something made of it? A question popped up in Wu Yun's mind.

"Can we still go up?" The grizzled Carlos asked the crowd not far away. At this time, everyone looked upwards and could only see the yellow sand walls around them.

"Is there sand like this under the ground where we just stood?" The fox cleared the sand from the shotgun. "No wonder it suddenly collapsed."

"There's no way we're going back." The squad leader added, "There's no need to go back." ”

"That's right, we're just going to move forward with our heads down." The fox looked at the hole below and muttered, "This isn't the entrance to hell, is it?" ”

"What will happen if we slide down?" Wu Yun's tone trembled slightly, he hoped that he was delusional, but his body did have a downward trend, but there was nothing around to grasp, and he immediately realized that his situation was extremely bad.

Everyone was shocked, apparently they were all aware of the problem, and the fox reacted immediately, and he picked up his shotgun and aimed it at the sand around him. Suddenly there was dust around him, and craters the size of a basin immediately appeared beside the fox. He stepped into the crater closest to him, and his sliding body immediately settled there, and the people around him understood his intentions at a glance. They all crawled towards the nearby craters.

Wu Yun and Wendy's location was far away from everyone, and the fox really couldn't shoot at the ground near them, because the scattering area of his weapon was very large, and if one of them didn't get it right, it would hurt them.

The squad leader unfastened his belt, pulled out a gray rope from it and tied it around his waist, and he threw the belt towards Wu Yun.

Wu Yun reached out and grabbed the belt thrown by the other party, and wrapped it around his arm a few times. His body finally stopped sliding, everyone was finally safe, and the fox breathed a sigh of relief.

"There's no way we can do that," Carlos suggested, "and it's only a matter of time before we fall." ”

"Then you can't just jump like that." There was a hint of helplessness in the squad leader's tone. "Do you remember when I said there was a powerful guy? I doubt it's here. ”

"Do you still have that rope?" Carlos looked at Wu Yun and asked the team leader.

"We all have military ropes hidden in the belts of our uniforms." The squad leader immediately understood his plan.

He nodded at the soldiers behind him, one of whom untied his belt and handed it to Carlos.

Carlos pulled out the rope and tied it to his body. Then the end of the rope was handed to the soldier.

"Look at the rope, I'll go and investigate." Several soldiers held the rope firmly in their hands. Carlos tugged on the rope hard, and when he confirmed, he began to slide slowly towards the hole.

I have to say that this is indeed a sound approach. Wu Yun admires these people's ability to act and adapt. This can only be tempered in a long battle.

"Be careful." The squad leader's face was heavy, he obviously didn't approve of this approach, but he had no better choice but to let him take the risk.

"It's fine." He had reached the edge of the hole, and he felt as if he was being pushed towards it. "Just remember to pull me back and you'll be fine."

With that, he jumped down from the hole, and the surrounding area was calm, and only the faint sound of sand grinding could be heard. Only a gray rope trembled in the sand, and everyone couldn't help but sweat for Carlos below.

"It's still too dark down there." Carlos's voice sounded faint through a large layer of sand. This is also to be expected.

"This is ... Hurry up.. Pull me! Suddenly Carlos's screams were heard below, and several soldiers hurriedly pulled the rope, which was stretched straight. Apparently there was no way to pull him up all at once.

"Ah~ Hurry up, it's coming!" The fox rushed over and grabbed his rope, but it didn't move. The crowd could only watch as he kept shouting.

"Snort~" Suddenly, his voice stopped abruptly. A stream of bright red blood spurted out of the cave like a fountain, and although the amount of blood seemed very large, it was a flash in the pan against the backdrop of the huge hole in the background.

Rao was like this, and the blood still stained all the edges of the cave in front of Wu Yun red. The fox and the soldiers finally pulled the rope. The feeling of watching them exert force is obviously much lighter on the end of the rope. They immediately retracted the rope, and with the blood-soaked rope came up ,—— Carlos' bloody lower body, which had been cut off at the waist! The legs that were still shaking were hanging there like a damaged doll...
