The light of the mobile phone is limited, and it can only shine within a few meters, and further down it is pitch black.

The inner walls of the passage are also made of stones, and it looks like the passage must have been dug for many years.

Xiang Yejun hugged Xiao Muqing, and the two walked towards the depths of the tunnel step by step with solemn expressions.

After walking for about ten minutes, I finally walked out of the passage, and inside was a huge stone cave, which was oval-shaped.

The inner wall of the stone cave is smooth and smooth to the touch, and he looks around in the direction of Yejun's mobile phone flashlight.

"Don't move, you see there are words and graphics on it." Xiao Muqing looked at the stone wall illuminated by her mobile phone, and suddenly grabbed Xiang Yejun's hand, letting the light stay on the stone wall she saw.

Xiang Yejun's cold black pupils also stared at the stone wall motionlessly.

On the stone wall, there are many patterns engraved, which are not complete patterns, but more like an ancient text.

There are shapes like the sun, the moon, people, and so on...... These shapes are strangely distributed throughout the stone wall, as if people from ancient times were recording something in their words at that time.

Xiang Yejun clicked on the mobile phone camera function and took pictures of the pictures and texts on the stone wall.

Xiao Muqing also took out her mobile phone to take pictures of all this.

"This must be the end of the cave, right?" Xiao Muqing was no longer afraid, took her mobile phone to illuminate it, and looked around in the stone cave.

"Yes!" Xiang Yejun replied coldly while taking pictures.

"So what's the sound we just heard? There's no one here at all......" Xiao Muqing was puzzled.

"Let's leave first, I'll ask Mu Ye to bring someone over to investigate." Xiang Yejun took Xiao Muqing's hand and walked out of the cave.

The two of them climbed out of the cave, and Xiang Yejun immediately called Mu Ye.

In less than half an hour, Mu Ye rushed to the mountain behind Xiao's house with his bodyguards and the company's research team, and everyone entered the cave with Xiang Yejun and Xiao Muqing.

A group of people walked into the cave with a whirl.

The bodyguards also lit torches one after another, illuminating the cave.

"Help--help--"

Suddenly, another miserable cry sounded in the cave.

Everyone paused.

Xiang Yejun's ears are extremely sensitive, but he still hasn't heard where this voice is coming from.

"Keep walking!" Speak to the night and command.

Everyone followed Xiang Yejun and Xiao Muqing and continued to walk forward.

Finally returned to the innermost stone cave again, and Xiang Yejun led Xiao Muqing into the stone cave, and Mu Ye followed closely behind......

Next, the bodyguard just wanted to step in, only to hear ...... "dong ......".

The body seemed to have hit something and made a strange noise, obviously there was nothing in front of it, but the bodyguards just couldn't get in.

The bodyguard stepped forward a few more times, "Knock-knock-knock--", which seemed to be like an invisible wall, thus isolating the bodyguard from the outside of the cave.

Mu Ye looked at Yejun, and then stepped out of the stone cave again and stepped into the tunnel.

He came and went as he pleased.

Returning to the cave again, the bodyguard behind him leaned forward, wanting to follow the advance.

With a bang, it was bounced out again.

Still can't get in.

In this way, more than two dozen bodyguards and researchers can't get in.

Xiao Muqing couldn't believe her eyes, obviously there was nothing at the entrance of the stone cave, but why couldn't the bodyguards get in?

After repeated trials and attempts, they all ended in failure, and there was no way but to stand at the entrance of the cave, holding a camera, and taking a clear picture of the words and patterns on the inner wall of the cave, intending to take them back for study.
