Gu Yu breathed a sigh of relief and climbed up with his hands on the stone platform next to him. He listened to the long stone platform roads arched like an overpass, crisscrossing like a net, connecting the entire mountain from bottom to top.

"What a big deal."

He sighed in his heart and turned on the walkie-talkie:

"The cave is about fifteen meters under the water. You can follow the suction force after diving for five meters. The mountain is safe and you can rise out of the water immediately after being sucked into the cave."

The water inside the cave is as high as outside the cave, so once you enter the cave, the water will surge up in a moment.

Soon, the fat man appeared inside the mountain, staring at a searchlight with his big head.

Guyu greeted him over, and the two sat on the stone platform waiting for the others.

After a while, everyone was in their seats and sat on the stone platform. They all admired Gu Yu's courage. They used the searchlight to observe the interlaced overheads above their heads, and couldn't help but be amazed.

However, while amazed, he was full of doubts.

These strip-shaped stone platforms are vertical and horizontal, with railings on them, which are obviously formed by artificiality, but why do you need to hollow out the mountain like this? Any building has its function, even if it is a temple, but they cannot see what its significance is here.

Indeed!

Such a long stone platform that is crisscrossing across the top and bottom has no other meaning than being able to walk on it.

It cannot live in, there are no statues, and it looks like it is digging.

But Guyu and Mr. Ling did not have such doubts in their eyes.

Gu Yu found that Mr. Ling seemed to penetrate everything, and he took it for granted, because Mr. Ling, who was young, was too knowledgeable and quick-witted.

But Mr. Ling was also aware of Guyu, and was slightly surprised.

He secretly asked:

"I have an IQ of 280. I can only tell why I came here and how did he do it?"

Obviously, Mr. Ling can judge through observation that Guyu's IQ will definitely not reach a stunning level, at most, the genius value line is 140.

As for the IQ of the ordinary people, plus Guyu's age, deducting the childhood and the more than ten years wasted in school, Mr. Ling did not think Guyu could master such complicated knowledge.

You should know that to be able to judge the reason why this mountain requires mineralogy, biology, architecture, archaeology, etc. With the IQ of an ordinary person, he will never be able to master so much in his entire life.

But he was sure that Guyu must have had an insight into everything here, otherwise he would not have been so calm.

So, Mr. Ling felt that he had fallen half of Guyu's head, because Guyu had no doubts in his eyes, and he still had doubts about Guyu, which formed a gap.

For some reason, Mr. Ling subconsciously asked Guyu:

"Mr. Gu, where do we go next?"

Guyu pointed to the depths of the dark mountain and said:

"The answers are all in the way, you will know if you continue."

Mr. Ling was sure that Guyu's sect knew why the mountain was hollowed out like this.

"Mr. Gu is also good at mineralogy, biology and archaeology?"

Gu Yu shook his head and said:

"I dropped out of school in my second year of high school and I haven't learned anything, but I can drive an excavator."

Mr. Ling wondered:

"Then how do you know that going deeper is the answer?"

Gu Yu said inexplicably:

"Isn't this what life is like?"

A very philosophical sentence, but it gave Mr. Ling a clear answer.

"Oh, it turns out that he is so heartless."

At this time, when Dachuan heard the two of them talking, he judged that Mr. Ling had already understood everything here, and Guyu was the ignorant and fearless person, so he asked:

"Mr. Ling, do you see why this is built here?"

Mr. Ling nodded, stroked the sitting Shitai and said:

"It can only be built like this, not intentional, but must."

Li Xiaohua couldn't help but ask:

"But, why?"

Mr. Ling pointed to the lateral stone platforms and said:

"Those stone platforms are all fossils that wood has turned into over the years. Do you understand?"

His eyes fell into deep thought, and finally Dachuan's eyes lit up and he said in surprise:

"Mr. Ling, you mean, we are sitting on the branches of a huge fossil tree?"

"ah?"

"Oh my God, no?"

"Then, how big is this tree? It's taller than a mountain."

Mr. Ling nodded calmly and said:

"Yes, we are walking deeper on the branches of an ancient giant tree that has become fossils. We will see the main pole of the tree fossils. I believe that the inside of the main pole is the core of this mountain building, where we will know what the function of this mountain building is."

Gu Yu walked in front of him. When he heard Mr. Ling's words, he was extremely surprised. Fortunately, he turned his back to everyone, and others could not see his expression and expression.

"I have the ability of infrasonic waves to hear the outline of this huge tree. If it weren't for this, I would never be able to judge what this is based on my vision. Mr. Ling's knowledge is too terrible."

Mr. Ling's head that knew everything made Gu Yu feel inexplicably dangerous, but he really didn't understand why he had such emotions towards him.

And at this moment, Gu Yu must have one point, that is, when Mr. Ling first appeared in front of him, he had already subconsciously felt this danger.

Otherwise, he would never hide his abilities so deeply.

Because Guyu is a person who likes to show off!

"Why do you feel dangerous? It's so strange! But Mr. Ling is not as good as me after all. He thought this huge tree was fossil, but he didn't know that the main pole of this tree is still alive..."

With a hint of superiority, Guyu felt much better inexplicably.

Xiao Man'er followed Gu Yu, and then took two steps quickly, shoulder to shoulder with Gu Yu.

She knew very well that it was definitely the safest to be by the side of Guyu at this time.

After walking along this stone platform for more than ten minutes, everyone's searchlight saw the black cylinder standing in the distance.

They can't see how tall the top is, and they can't know how tall the big tree is.

But they were sure that they could not see the height at the end, but in fact they were just the canopy, while more tree poles were deep in the water and even extended to the ground.

This is the height they cannot measure at this moment.

After walking for a few more minutes, they came to the connection between the branch and the main pole.

When they came to the side of this huge cylinder, the searchlights on both sides looked over and there was no edge. It was unimaginable how thick the huge fossil of the huge tree was.

At the connection between the branches and the main pole, that is, at the end of the railing stone road, there is a moon arch, which has no door leaf, and can be directly entered.

Looking up, you can see that there is such an entrance at the end of each branch, just like an irregular tower.

One branch and another tower.

When they came to the main pole, they relied on the searchlights to illuminate the interior a lot.
