Chapter 4664: Found the entrance

"If we follow this speculation, then there must be some suspicious places underwater that are worth exploring."

Cai Dongyi nodded.

"If my speculation is correct, then there must be other dead fish underneath. If not, then it's the possibility Wen Jing mentioned."

Lin Yi and Ning Che thought about it and agreed that this statement was correct.

"Continue to follow the original plan. I'll go down and take a look. You guys guard the surroundings."

"understood."

Lin Yi went down into the water again. While checking the riverbed, he was also looking at the surrounding river walls. Maybe he could find a clue somewhere.

Continuing to check upstream, a beam of light came down from the flashlight.

Soon, Lin Yi's eyes were fixed on the riverbed!

There's a fish there!

Damn!

It sank to the bottom!

Lin Yi swam over quickly and picked up the dead fish.

The feel in the hand is exactly the same as the previous one.

After floating up, Lin Yi threw the dead fish over.

"I picked up another one, let's see what's going on."

The three of them's eyes lit up, which proved that their previous guesses were correct.

There really is some weird place down there where the fish eat the stones and get stuck.

After the autopsy, the situation was the same as before. Ning Che took the stone in his hand, weighed it, and then compared it. It was the same thing.

"I have a feeling that we are getting closer and closer to our goal."

Lin Yi nodded and dived into the water.

As the distance went deeper, he saw several dead fish one after another. This time Lin Yi did not pick them up because the basic situation was similar and there was no need to waste time.

As we go deeper, we can feel the water flow getting faster and the riverbed getting wider.

Lin Yi quickened his speed and swam all the way to the deep pool under the waterfall, but he did not find anything unusual.

After floating up, Lin Yi wiped the water off his face, but did not go to the shore. Several people came over.

"Did you find anything else suspicious?"

Lin Yi shook his head. "That's basically the situation up there. I'm going to go down to the lower reaches to see what's going on, so as to avoid missing anything."

At this point, everyone had no other choice but to give it a try.

After taking a breath, Lin Yi swam downwards again.

As the distance went by, he could clearly feel that the river was no longer so fast-flowing. Lin Yi also tried to slow down and check every place more carefully.

As I was swimming, an obstacle appeared in front of me.

The river was blocked. I swam closer and found that it was a dam built by beavers that blocked the river.

Lin Yi thinks these little animals in nature are quite cute.

The dam has been completed, and it is no longer possible to pass through here. After Lin Yi floated up, he found that the river here was a tributary and he had to go around to the other side.

I took a breath and continued to dive, preparing to change direction.

But at this moment, Lin Yi discovered something different.

A crack appeared below the blocked river channel. The crack had been blocked by branches brought by the otter, but some of the previous appearance and shadows could still be seen.

Lin Yi was very curious, so he swam over and found that the crack was larger than he had imagined, but it was blocked by dense branches. In addition, the water flow here was extremely slow, so no problems had occurred over the years.

Lin Yi's heartbeat inexplicably quickened, and he felt a nervous feeling that the answer to the mystery was about to be revealed.

Gently pushing aside the branches, the appearance of the crack appeared. There were a large number of branches piled up inside, as if it was used as a warehouse.

I gently took out all the branches inside and found that the hole was very deep. I put my whole arm in but couldn't reach the bottom.

He picked up a long stick, about two meters long, and slowly pushed it in, but it still didn't touch the bottom.

This is also in line with ideal imagination.

He thought there was probably something fishy going on here, and perhaps the entrance to the mountain was hidden here.

The crack at the entrance of the cave is not very big, barely enough for one person to pass through.

Lin Yi held a dagger in his hand and cut some of the surrounding soil, so that he could move a little more freely.

Just like that, while swimming inside and clearing the branches inside, Lin Yi was also observing the terrain under his feet. It seemed that he was walking upwards, and at the same time he judged his current location.

The tributaries of the stream have spread to the foot of the mountain, so where I am now is also at the foot of the mountain. If I go further up, I will be able to enter the interior of the mountain.

I have been diving for a long time. Although I have been controlling my breathing rhythm, I still feel a little short of breathing and need to surface for breathing.

But Lin Yi was not in a hurry. He looked down with the flashlight.

The dead fish sank to the bottom of the river because they ate high-density stones and were eventually choked to death.

If this is the entrance, then this kind of stone should exist, otherwise another doubt will arise: where do these stones come from?

Soon, Lin Yi's guess was confirmed.

Several such stones were found in the soil below the cave entrance, and some of them were quite large, about the size of a fist, and quite heavy in the hand.

Lin Yi's expression was relieved, everything was consistent with his guess.

Because the situation was not very good, Lin Yi had to retreat and go to the shore to breathe.

Several people came over and found that Lin Yi was in a rather miserable state.

Not only was my body wet, but there was also a lot of mud on it.

"How did it become like this?"

"Found a clue down there."

Afterwards, Lin Yi took a few minutes to tell the three of them about his findings below, and the three of them were greatly encouraged after hearing it.

"Then there won't be any problem. There is a high probability that the hole leads to the ruins."

Lin Yi nodded and looked at Sheng Wenjing and Cai Dongyi.

"First, go get our communication equipment from the car, and then you two stay up there to guard it. This place is very unsafe. Without anyone up there, we can't rest assured down there either."

"understand!"

At this time, orders must be obeyed and there is no room for bargaining.

The two returned to the car and took out the communication equipment. Lin Yi and Ning Che put them on, then dived into the water and came to the location of the cave entrance.

The two men went deeper inside, one in front and one behind, while shining flashlights forward. They found that it was pitch black in front of them, without any reflective area. This confirmed their previous speculation that the cave was deeper than they had imagined, and the place it led to was most likely the ruins in the mountains.

The two continued to move forward, holding their breath while also speeding up.

About two or three minutes later, the two men floated out of the water, wiped the water off their faces, and breathed in deep gulps of air.

I shone the flashlight and found myself in a dark space...
