This figure attracted the attention of Lin Feng and Xiahou Wen.

They looked quickly in the direction from which the sound came, and indeed there was a deep pool in that place, because there was a grotto that was half covered by water, so they got a pump and kept pumping water.

They wanted to drain the water so that the cave at the bottom would be completely exposed.

In fact, this work has been going on since yesterday.

At first it was just a small pump working.

But later, they found that such a small water pump would not work at all, so the staff of the Divine Investigation Bureau coordinated and transferred some water pumps from the relevant construction units.

Two large pumps enter the water and start pumping.

After about a night of this, until just now, the cave below was finally revealed, and it was a statue of a Bodhisattva.

In addition to this Bodhisattva statue, next to the Bodhisattva statue, in the lower place, there is also a cave.

Now.

The cave is only half exposed, and the Buddha statue in it is not visible for the time being, although this cave may also be a very deep cave.

Lin Feng jumped to the side of the waterhole from above, and behind, Xiahou Wen also followed, and the staff next to him said that the two pumps worked at the same time, and the effect was okay, but there was too much water in this place, as if it couldn't be pumped out.

After the water level reached this place, it had not gone down for a while.

The staff asked.

"Do we want to keep pumping?"

Xiahou Wen said directly.

"Of course you have to keep smoking!"

"The more difficult it is, the closer we are to the answer!"

Xiahou Wen's words are true, Lin Feng also feels that the answer may be in this cave, the dragon bone Luoshu, born when encountering water, Li Wei's tomb is very likely to be built under the waterhole, so the one below may not be the cave, but the entrance to Li Wei's tomb.

And some of the Buddha statue caves built on these rocks are to confuse people and make people mistakenly think that these are Buddha caves, so as to achieve the purpose of protecting their tombs from being discovered.

Said the staff.

"Our two big pumps are running at maximum power, and the water is draining very fast. However, I observed that half of it had disappeared, and the water level in this pool had not gone down at all!"

Xiahou Wen said.

"If the water level can't go down, it must be that the horsepower is not enough."

"I remember when I was coordinating the high-powered pumps, I brought in 10 pumps from a construction company. Now, with those ten pumps in use, I don't believe that the water level in this pool will not go down!"

The staff was surprised that all ten of the large pumps were used, and almost the entire waterhole was filled.

But now this situation, if there are not enough pumps, there is really no other way to solve it.

Then.

Lin Feng jumped up in the air and landed in the cave in the waterhole.

He pressed his ear to the stone wall and listened carefully.

The water pump is too noisy.

Lin Feng ordered.

"Turn off both pumps first!"

Those people looked at Xiahou Wen, and Xiahou Wen said directly.

"This is called Lin Feng, Mr. Lin, he is my Xiahou Wen's boss, in the future, his order will be my order, you don't need to ask me!"

They really didn't know Lin Feng, but Xiahou Wen's words made these people's views of Lin Feng, a young man, directly change very much.

The men immediately moved and turned off the electric switch.

When the pump is turned off, the water level should normally be reversed, but if you look closely, the position of the water surface of the pool has not changed without drainage. It's like, there is no difference between pumping and not pumping.

In fact, it certainly isn't.

Lin Feng looked at Xiahou Wen and said.

"Steward Xiahou, you flush a stone into the pool, try to get as close to the cave as possible!"

"Good!"

Xiahou Wen quickly squatted down, picked up a stone, aimed at the vicinity of the cave where the water level was relatively deep, and threw it in.

Boom!

Ripples rippled in circles on the water.

Lin Feng stuck to the stone wall, listening carefully to the subtle movements. Lin Feng's power of the five senses was very powerful, and when he could hear it, everyone else held their breath and remained quiet.

Within this mountain, there is an echo.

After listening, Lin Feng seemed to have an answer, he reflexively exerted his strength, and jumped out from that side.

A staff member of the Psychic Bureau next to him said.

"Unexpectedly, Mr. Lin is young and knows how to listen to the mountains?"

Lin Feng had naturally heard of the word Tingshan, when he was imprisoned before, when he was learning some antique knowledge, he had learned the techniques of some tomb robbers, and Tingshan was a way to find tombs in the mountains.

When Mo Ziyan trained Lin Feng's five senses of hearing, the method used was the method used by tomb robbers in the old days to train the ability to listen to mountains.

The real masters of listening to the mountain, most of them have a very high status in the Tumen.

This kind of person doesn't need to go to the tomb, they just need to help their family sect or team go to the mountain, and after determining the location of the tomb, he will call it a day, and the rest of the dirty work will be done by others.

Listening to the mountain master, most of the tombs found are large tombs.

This kind of person, combined with feng shui and stargazing, will continue to look for the best rocks on the mountain after entering the mountain, especially the kind of mountain stone, which is the kind of stone that can connect the mountain rock formation, to knock, and listen to it.

The slightest change in sound can be used to determine whether there are tombs in this mountain.

Even, judge the size and location of the tombs in this mountain.

Generally, this method finds large tombs, and when the tombs are built, they often cut off those even mountain stones, and even, directly hollow out the mountains and chisel out the tombs, so as to establish an underground palace palace.

Whether the rocks have been chiseled or not, the listeners can hear when they strike with the stones.

Of course, these are to be combined with ancient feng shui and stargazing, if not, some of the places that have been chiseled may also be artificially mined caves, or natural karst caves.

The method Lin Feng used was really listening to the mountain technique.

So, Lin Feng smiled and said.

"It's just a little trick to carve insects."

The man waved his hand and said.

"Little Mr. Guo Qian, this mountain listening technique is said to have been lost for many years, you can listen to the mountain at a young age, and admire it below!"

In fact, in Lin Feng's opinion, this kind of mountain with a water hole is the easiest mountain to hear, the water hole leads all the way to the depths of the mountain, and if you throw a stone into the water, you can hear the movement in the depths of the mountain very directly.

It was verified just now, and sure enough, the grotto at the bottom was not carved with a Buddha statue, but directly led to the depths of the mountain.

Keel Luoshu is born when it meets water.

Li Wei's understanding is to bury his bones and Luo Shu in the water, so as to seek his descendants and develop again. In fact, Li Wei's water burial behavior, Shen Wansan, the richest man in the Ming Dynasty, also did so.
