After a while, Sun Datou took the lead and walked to the huge stone and exclaimed: "This stone is really big!"

Hearing what Sun Datou said, several other people following him came over one after another.

Before, when I was about thirty meters away, I felt that the boulder was very big. When I got closer, I felt more intuitively that the boulder was huge, like a hill, and it looked dark, which made people feel a sense of oppression involuntarily.

"Huh? There is a crack next to this boulder!"

Sun Datou suddenly discovered the clue and exclaimed.

Hearing what Sun Datou said, several people following him came over one after another.

Sure enough, a crack appeared on the top of the boulder near the stone wall of the sinkhole.

The crack was not big, and it looked like it could only fit two fingers.

But this crack is very long. From the top of the boulder, it snakes upward along the wall of the sinkhole. It is at least tens of meters long by visual inspection.

"This crack seems to have just formed not long ago!"

Sun Datou shined a strong flashlight on the crack, and after observing carefully for a while, he suddenly said this sentence.

"Uncle Big Tou, how did you tell that this crack was just formed?"

Hearing what Sun Datou said, Lan Qingling couldn't help but ask him.

"Here, take a closer look. There are some gravel chips on the ground under the crack. They should have fallen when the crack opened."

Sun Datou answered like this, and shone a small flashlight with a strong light on the surface.

Everyone's eyes also followed the light beam and they saw some gravel chips on the ground, falling on the withered vines and thick fallen leaves everywhere.

"If this crack had already formed, the fallen gravel would have been covered by vines and fallen leaves."

Sun Datou explained it this way again.

"Uncle Sun's explanation does make some sense! The hunter's observation skills are extraordinary!"

Yu Baiying also agreed with Sun Datou's explanation and even praised him.

"Hehe...these are professional habits."

Sun Datou replied with some embarrassment.

"If this crack is new, how did it form?"

Lan Qingling raised this question again.

"Um...I don't know at the moment."

Sun Datou responded helplessly.

"This new crack will definitely not appear for no reason. It should be caused by some reason!"

Hua Canghai, who had been silent until now, suddenly interrupted.

"Old Man Hua, do you see the reason?"

Lan Qingling immediately asked Hua Canghai out of curiosity.

Hua Canghai did not answer Lan Qingling's question, nor did he pay attention to the crack, but circled around the boulder.

Lan Qingling pouted her little mouth and muttered in a low voice with dissatisfaction: "Old Man Hua always likes to do such appetizing things!"

Hua Canghai didn't seem to hear Lan Qinglingfa's complaints. Even if he did, it didn't matter. He was used to it anyway.

After walking around the boulder several times, Hua Canghai suddenly said: "This boulder is not a natural thing here."

"Uh... Mr. Hua, are you saying that this huge boulder is not naturally formed under this sinkhole, but is a foreign object?"

Sun Datou was shocked when he heard this and asked Hua Canghai Road like this.

"Yes!"

Hua Canghai nodded, his tone quite affirmative.

"Old Man Hua, are you kidding me? For such a big stone, if not hundreds of tons, it must be dozens of tons! Who would be so bored as to carry it into this sinkhole?"

Lan Qingling didn't believe Hua Canghai's judgment, so she retorted.

"I don't have time for jokes!"

Hua Canghai replied, and then said: "Look carefully, first of all, the color of this boulder is different from the color of the stone walls around the sinkhole, and there are traces of artificial work on the boulder."

After hearing what Hua Canghai said, everyone noticed that the stone walls around the sinkhole were gray in color, while the boulders were dark black. The colors between the two were indeed different.

Sun Datou knelt down and held up a small flashlight with a strong light to shine on the bottom of the boulder.

Following the light beam of a strong small flashlight, Sun Datou observed carefully for a while and discovered that although the surface of the boulder looked uneven, there were several pits at some locations at the bottom.

Sun Datou counted carefully and found that there were eight pits in total. They were evenly distributed at the bottom of the boulder, and there were some traces of digging.

"Sure enough, this huge boulder was not formed naturally, but was transported here!"

Sun Datou also came to this conclusion and murmured: "It's really strange. Who brought such a huge boulder here and how did it get here? And what's the purpose?"

Hearing Sun Datou's exclamation, everyone was puzzled.

After all, it is difficult to transport hundreds of tons of boulders to the bottom of a sinkhole as deep as 200 meters, even with modern heavy-duty vehicles.

What’s even more strange is who brought the boulder here? What’s the purpose of doing so?

So many questions are unimaginable...

Su Yuan also circled around the boulder and observed it carefully, because he felt that the boulder was not only abrupt, but also had an indescribable strangeness.

"Brother, this big stone is pitch black, what's so interesting about it?"

Lan Qingling followed Su Yuan step by step, mumbling questions to him.

Su Yuan shook his head and replied: "There is something weird about this stone..."

"What's weird? Why can't I see it?"

When Lan Qingling heard this, she immediately opened her eyes wide and stared hard at the boulder, but she couldn't figure out why.

Su Yuan didn't reply. After walking around the boulder, he suddenly leaned down, stretched out his right hand and started groping for the bottom of the boulder.

After groping for a while, Su Yuan's right hand suddenly touched a sunken spot.

The concave position was just the size of a palm, so Su Yuan subconsciously pressed his right hand into it.

Click!

A strange sound sounded, and the boulder shook.

"Huchi..."

Immediately afterwards, a dark wind suddenly surged out from above Su Yuan's head.

Su Yuan hurriedly looked up and saw a puff of gray-white mist pouring out from the crack.

After the mist overflowed from the cracks, it quickly condensed in mid-air and formed more than a dozen mist clusters of different sizes, spiraling upward toward the top of the sinkhole.

After the dozen or so fog clouds rose to the top of the sinkhole, they suddenly dispersed.

In an instant, a vast and thick fog filled the sky above the top of the sinkhole.
