"Such a big lake on the map!"

"Is it possible to take the waterway instead of the dry road?"

Lin Qiye suddenly had an idea.

"If there are aquatic monsters or demons lurking under the Emerald Lake, and they happen to have the ability to dig water channels... then the water channels at the bottom of the lake are the most secret!"

"Although it is very difficult to operate underwater, with the cunning level of the mind flayers, they will definitely operate from underwater. Not only can they maintain a high degree of concealment, but they can also use sewers to cover their eyes and ears, allowing humans to waste time in the sewers.

!”

"For example, right now, the human demon hunting group has been searching the sewer system for two weeks, but still found nothing, buying the Mind Flayer precious time!"

Lin Qiye suddenly realized.

Seize the fleeting breakthrough.

"Emerald Lake covers an area of ​​800 acres, with a maximum water depth of 80 meters. It is a natural lake. There have been no evil spirits and monsters in it for many years. Moreover, human hydrology monitoring is extremely strict, so it is basically impossible to quietly dig underwater channels.

"

"It will definitely leave a mark!"

Lin Qiye's eyes were blazing. At this time, his thoughts were extremely smooth.

Immediately open the hydrological records of Jiangcheng in recent years.

as expected.

Lin Qiye discovered something unusual.

"Ten years ago, or even five years ago, the water level in Emerald Lake would surge by about three meters every time there was a heavy rain. But in the past three years, every time there was a heavy rain in Emerald Lake, the water level only fluctuated by 10cm..."

"Based on the data analysis of the heavy rain a year ago, the water level should have risen by five meters, but it only rose by 10cm."

"If there is a problem, there must be something wrong. If there are aquatic monsters digging tunnels below, they will definitely work during heavy rain periods. They will use the heavy rain to cover up the underwater movements.

Lin Qiye smiled slightly.

Basic guesses came to mind.

"So, what kind of aquatic monster is it that works underwater?"

Lin Qiye frowned and thought.

There are not many monsters that can open channels underwater.

Lin Qiye opened the news from three years ago.

Browse one by one.

In the midst of complicated information.

Lin Qiye noticed a piece of news.

"An unknown collapse occurred in a limestone vein outside Jiangcheng, death toll: sixty, serious injuries: twenty-one."

Investigation showed that the bottom of the limestone vein was swallowed up by unknown creatures, and the entire mine suddenly collapsed while the miners were digging.

Because the height of the fall reached more than 200 meters, sixty-four miners fell to their deaths.

After an investigation by the Demon Hunting Group, the result was that some unknown monster caused the mining disaster.

"This mining accident is definitely related to the creatures under the Emerald Lake. The mine is 226 meters high, 300 meters wide, and 600 meters long. To swallow so much limestone minerals, a passage must be built.

So...what monster needs calcium carbonate to grow?"

this period of time.

Lin Qiye studied like crazy.

It finally worked.

Several images of monster beasts appeared in Lin Qiye's mind.

"Is it a coral monster? Some hard coral monsters need calcium carbonate to build their skeleton when they grow."

"Under the control of the mind flayer demon, the coral monsters can indeed work together to construct a passage. It is even possible to construct an elevator passage.

The Blue-Winged Wolf King might have come quietly from inside Jiangcheng through the lift channel!"

While muttering to himself.

Lin Qiye made a bold guess.

Although, this is just speculation.

But his intuition told Lin Qiye that he was getting closer to the truth.

Under the Emerald Lake.

There must be a group of coral monsters opening a passage.

As for how the coral monster entered the Emerald Lake and how to open a passage, Lin Qiye didn't know.

but.

None of these details matter anymore.

The important thing is - Lin Qiye thought of a 'targeted plan'.

"If it is a coral monster digging a tunnel underneath, it will be easy to deal with. Coral can hardly walk and its strength is not high. It would be too easy to crack it."

Lin Qiye smiled slightly.

He stretched lazily.

Then.

Holding a copy of "One Hundred Thousand Whys", I walked out of the room.

In the living room.

A team of seven, including Father, Mother, and Uncle Zhao, were sitting around the map of Jiangcheng, pointing and talking.

Apparently he was looking for a breakthrough.

at this time.

Father Gu pointed to the Emerald Lake.

"With two weeks of work, the sewer can be cleared for the time being."

"Except for the sewers, there is only the Emerald Lake, right? Is there a possibility that the monster entered Jiangcheng from the bottom of the lake?"

Hear the words.

Captain Zhao shook his head: "Dig a passage at the bottom of the lake? Isn't it too difficult? Not only is it easy to fill with water, but the sediment at the bottom of the lake is not stable, and it will collapse if you are not careful..."

"Under the influence of so many unfavorable conditions, digging a passage from the bottom of the lake that can allow the Blue Winged Wolf King to pass through will definitely cause some movement that the awakened ones will notice, right?"

"But the awakened ones checked the bottom of the lake and found nothing unusual, right?"

"I don't think it's credible to dig a channel from the bottom of the lake."

Uncle Xiong also shook his head: "What aquatic monster is qualified for this project? A sea crab, or other monster that can dig caves? There seems to be no similar monster, right?"

Opposite Uncle Xiong.

Uncle Li used a portable computer specially used to perform tasks and called up a series of information.

After looking at it carefully for a while, he finally raised his head.

"A year ago, Jiangcheng's Demon Hunting Group investigated the bottom of Emerald Lake and found nothing unusual. The terrain at the bottom of Emerald Lake has not changed much. The underwater biota are all very normal. It should not be a problem at the bottom of the lake."

Hear this sentence.

Lin Qiye shook his head slightly.

Looks like I have to be Conan for once.

Unfortunately, there was no sleeping needle. Lin Qiye could only stand up and said with stern features: "It must be at the bottom of the lake."

Lin Qiye's sudden voice interrupted everyone's discussion. They looked surprised and turned to look at Lin Qiye, who had a serious face.

"Xiao Shaoshang, what are you talking about?"

"Are you talking to us?"

"Yes, my point of view is that the channel must be at the bottom of the lake. You can search for the hydrological changes of Emerald Lake in the past three years and the past ten years. You will understand when you see the hydrological changes."

Hear the words.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Uncle Li immediately used the computer to retrieve the data on hydrological changes.

But I watched it for a while.

Everyone's expressions were still blank.

"Is there any way?"

"I don't see any clue at all..."

Aunt Zhou, the wet nurse, raised her eyebrows and racked her brains, unable to figure out what secrets were hidden in these data.
