What was going on?

That girl called Qin Yue fell in front of me just like that.

"Qin Yue!" Zhou Dingshan shouted, and a few of them knelt at the edge of the whirlpool to look down.

The vortex was several meters deep and appeared to be square in shape. Unexpectedly, there were sand dunes beneath this strange rock. Qin Yue had already disappeared.

"Where is he? How could it sink in? " Cheng Faang's eyes kept on looking down, and just as he was about to jump down.

It was obvious that he was more nervous than anyone else. On the way here, he humbly requested for Qin Yue to come. He definitely had some interest in this girl.

Why did this girl fall down just like that? One moment he was asking around behind me, the next he was gone.

Cheng Faang was very excited, so we quickly pulled him back.

"Don't get too excited, we'll think of a way to save her." I said to him.

I took out the Yutian Spear, "Magnification, Swift!"

The Yutian Spear in my hands instantly enlarged and I filled up the gigantic sand pit with my Divine Equipment. The blue light illuminated the deep pit a few meters below.

"Still there?" I shouted down below, almost with all my strength. There was an echo in the pit, and my voice was monotonous for a long time, making everyone's heart sink even deeper into the valley.

I didn't expect so many accidents to happen before we even reached our destination.

"Yue Zhiyun, you can't die! I'll save you! " After Cheng Faang finished speaking, he was about to pull the Yutian Spear and slide into the pit, but I stopped it.

"I'll go in. You wait outside." I told him sternly.

"No, I want to go in. I want to go in and save him." Cheng Faang was very excited, and was about to jump down.

"Are you crazy? Cheng Faang, you have to be rational, your ability is the lowest inside, we still need you to make records on the way here, you should go ahead and take care of the Little Ancestor. He will rescue Xiao Yue. " Jiang Feng was very rational, he pulled Cheng Faang's arm and said.

I patted Cheng Faang's shoulder, "Don't worry, I will definitely save her."

Seeing that Cheng Faang had calmed down, he immediately took out a rope to tie to his body, and tightly embedded the other end of the rope into a large tree behind me.

Afterwards, I firmly fixed the lance into the hard sand. After confirming that it was solid, I slid down.

The more I went down, the wider the sandpit became. How many meters? A dozen meters or so, because my feet haven't hit the ground yet.

I can still feel the soft sand as I slide down, and it's getting harder now. There was sand all over his body.

Once my feet touched the ground, my Yutian Spear was shrunk by me. I turned on the little light overhead and looked up, like a frog at the bottom of a well. There was only a dot at the entrance.

When the lights came on, I looked around. It was wide. To my surprise, it was a man-made basement. Curious, I touched the sand walls. The sand fell off in a flash and I felt smooth.

The so-called sand cave was also known as the sand space.

In the dim light, I could see the faint outline of something on the sand walls. I lay down on my stomach to remove the adherent sand, which turned out to be a totem.

Totem again? These totems are identical to the ones we saw on the male corpse in the grass. Every black totem was emitting a sinister and evil aura.

I lay down on the sand on the four walls. The sand was extremely hard, and it looked very old. The yellow sand had already turned black.

This side was filled with totems, and there were even some inscriptions similar to symbols that could not be understood.

Could this be the underground passage dug out by the Uggawaga people? What was it used for?

At this moment, in a corner not far from me, Qin Yue woke up.

No, he should call him Yue Zhiyun.

"Yue Zhiyun, how are you? Are you alright? " I indifferently supported her. She tilted into my embrace and raised her head to look at me in astonishment.

"You … Why did you come in? Is it to save me? "

I deliberately ignored her excitement and helped her up, "Fortunately, she wasn't hurt. We have to get out of here. "

"It's just that when I fall into the sandpit, the sand is soft, so I'm fine. Why are you so nervous? " She looked at me, confused.

"It's not safe here. "Just look at the totem on the wall." She followed the direction of my finger and looked at the wall. The floor was covered in black totems and strange words. It was as if we were surrounded by them.

"Brother Zu, I see these things very uncomfortable and I'm a little afraid. Let's hurry up and go up." Yue Zhiyun trembled a little after speaking.

"The rough sand on the sand wall is natural, but the surface is covered with totemic symbols, what does this mean? I think this must be the place for witchcraft. " Just as I said that, she grabbed my arm and cast nervous glances at me.

"Brother Zu, this place looks pretty big, and there's no end in sight. I think maybe the people from Uggawaga dug up a concealed underground execution ground? If that's true, then wouldn't there be a lot of lonely ghosts here? " After saying that, she gave a start, causing me to feel a bit nervous.

I raised my head to look at the height before continuing my analysis, "I thought it was only a few dozen meters, and from the looks of it, it should be at least twenty meters. "Even if we have to carve totems and symbols on top of the sand walls, it would take a lot of effort and resources."

"Brother Zu, actually, I am also an archaeologist. I've been involved in archaeology for more than three years, and I've also been to a few small and medium-sized mausoleums, but I've never seen these words before. "So ancient, so old that it was even older than the Oracle Bone …"

At this time, a large amount of yellow sand suddenly fell down without any warning. It was at least six to seven meters high, and this way, it blocked the entrance.

I just pushed her over in the nick of time. We looked at the yellow sand in shock.

Yue Zhiyun released my arm, and angrily and emotionally went forward to pluck and kick Huang Sha. However, the sand didn't respond, as if it was stuck to the ground. She moved for a long time, and only light sand rolled down from the high ground.

"Alright, stop pestering, hurry up and find another exit." I told her with a trace of loss and hope for survival.

We moved forward carefully, and Yue Zhiyun's face turned pale. For before us lay a river.

The river was narrow and not deep, and I looked at her. "The exit here is sealed, and I think Professor Zhou and the others must be trying to figure it out, but as far as I know, it's very difficult. I found a small hole in the sand that was blocked by a lot of sand that I dropped when I slid in. "

"So?" she asked simply.

I touched Barton and paused. "So I think the two caves should be connected. This river should be connected. As long as we swim over there, we will be able to enter the small sand cave. We will be able to find the exit. "

Yue Zhiyun suddenly clapped her hands, "Alright, then we'll swim to the small sand cave before we go out."

"Will you be okay swimming?"

She nodded.

"Just follow me." I dropped a sentence and took a small oxygen cylinder from my bag and put it in her mouth. I bit one and jumped down.

At this moment, she also jumped down.

However, we didn't notice that the black fog that was flowing out from behind us had directly passed through the sand and sand into the small sand cave. It was as though we were waiting for a game of death …
