"..." Jiang Xia thought for a while, but in the end he didn't say anything: it would be difficult to go back the same way now, so why don't you just go deeper down the cave and get out on the other side.

Based on current trends, there should be some good stuff over there.

Conan, Maurilan, and Suzuki Sonoko saw Sachiko Nakamura who was in a strange state. After asking about the situation, they suddenly felt that something was wrongtheir ankles were wet by the flowing sea water.

"...you have to leave quickly, the later it is, the harder it is to leave!"

was about to take Nakamura Yukiko to the boat when suddenly there was a loud bang.

The sea surged, the sea water poured in from the outside, and was enlarged by the accumulation of narrow caves. A wave hit hard, and the boat parked next to it was overturned by the waves, and it was knocked upside down.

When Mao Lilan turned around, he saw a shadow looming over him.

She was taken aback, and flew to throw away Yukiko Nakamura next to her. The old boat brushed past them, smashed against the hard rock, and thumped twice, and the boat board actually cracked a gap the size of a slap.

Suzuki Sonoko was stunned for a while, and said sadly, "What quality is this ship!"

Jiang Xia sighed: "It was originally a garbage ship. It was exposed to the wind and the sun all the year round. It's normal to forget to maintain it... When you go out, let the owner replace it with a new one."

Conan looked at the sea and the shadows in the depths of the cave, his expression became heavy: "Let's think about how to get out first."

Maurilan supported Sachiko Nakamura, his face was pale, and he blamed himself: "I didn't dodge it just now, just try to catch it."

Jiang Xia: "..." Calm down, you don't have such a high defense setting.

"With the current tide and water, and the reefs outside, it may not be easy to swim out." Jiang Xia suddenly pointed to the depths of the cave, and changed the topic, "Have you found it? There are fireflies in the cave."

Suzuki Sonoko glanced up and secretly wiped away tears: "Indeed, it may be more romantic to die next to fireflies than to swim out..."

"..." Conan looked at the classmate who had lost his desire to survive early and started to organize his clothes, and his eyes jumped: "Brother Jiang Xia probably wanted to say, we can go from there.

"According to the Sachiko method, this sea cave is filled with high tide sea water twice a day. In this environment, it is unlikely that fireflies will settle in the area around the entrance of the cave.

"The entrance of the cave is far from the sea, and there are no other fireflies on the shore. They should not have flown in from the sea, but from the passage on the other side."

Mao Lilan vaguely understood and was pleasantly surprised:

"In other words, as long as we follow the cave to the depths, we can find the land and the exit on the other side? But... what if the gap can only allow fireflies to fly in, but not allow people to pass through?"

Jiang Xia remembered that she was going to pick up the boat with her bare hands just now, and said casually, "Then smash the hole open."

"Break open?" When Mao Lilan heard this, he looked down at his fist. After a while, his eyes gradually became firm.

"...Wait, I'm joking." Jiang Xia worried that he had accidentally awakened something terrible, and said sternly, "Actually, when I was driving over the bridge yesterday, I saw a small lake diagonally below, around the lake. There are glowworms - if you count the location, it's probably across from this cave.

"And this morning, there were people in the hotel who fished in that small lake. I have seen their catches, and they were all large sea fish. It should be that when the tide was high, the fish swam into the cave filled with water, and the tide was low. It was swept to the other side of the lake. At present, it seems that after falling out from the other side, even the very large fish have no scratches at all, and the hole must be much larger than the fish itself."

He gestured the size of the fish: "In short, that should be the range we can pass."

decided to go deep into the cave, and a few people took Nakamura Sachiko, who was still wobbly, and entered the cave behind.

The passage is dark and long, but not silent. As I walked deeper, I could hear the sea behind me slowly rising.

This sea cave is not small, and the inside is like a huge labyrinth with countless forks.

Fortunately, there are fireflies to guide the way. The five people moved forward smoothly by finding the place with the most fireflies.

Although Conan's watch is illuminated, this environment is inevitably disturbing.

Suzuki Sonoko followed Jiang Xia forward, and whispered with a sense of urgency: "I always feel that there are fewer and fewer fireflies. What if I can't see them later and can't use this to find a way?"

The time in the cave is not infinite - the sea could come up at any moment and fill it up. If they took the wrong fork and entered some dead end, they probably wouldn't have the chance to look back.

"No fireflies?" Jiang Xia thought for a while, "Then throw stones to listen to the echoes, observe animals - such as fireflies or birds feeding in holes, look at the direction of moss or other plants falling down, and the traces of water flow on the rocks." Finally, let The foggy dogs flew one by one at the fastest speed to see which road was the most suitable for people to walk.

If Fog Tengu is not enough, add mermaid and spider lady.

Jiang Xia silently gathered up his clothes while watching the ghosts floating around busy.

walked forward for a while, behind the side of the raised rock, a strange thing appeared.

It was a pink plastic thing. If you put it outside, the color looks cute. But it suddenly appeared in this desolate seaside cave, and everything suddenly became weird again.

Conan ran over curiously, illuminated it with a flashlight, and looked at it carefully: "It's a dead swimming ring."

While speaking, he had already thought of the reason why this thing appeared in the hole: "The garbage that should be floating in the sea was washed in with the high tide. Other small pieces of debris would recede with the tide, or get stuck in the hidden In the gap, this one is relatively large, and it is very conspicuous after it gets stuck... eh?"

As he was talking, Conan's eyes suddenly landed on one place.

He originally thought that this was a deflated lifebuoy that was accidentally cut by a reef after drifting away.

But at this time, if you look closely, there are no scratches on the lifebuoy, but there is a pinhole in the corner.

In an instant, all kinds of information are quickly stacked and combined.

Conan's mind had a flash of lightning: "I understand!"

Suddenly there was a shutter sound next to it.

Jiang Xia took a few photos of the lifebuoy, then put on gloves, bagged it up in a ball, and stuffed it into his backpack: "Go quickly when you understand, the sea is coming soon."

Conan was stunned, and the excitement just now became dull in an instant: "...You understand too."

Jiang Xia glanced at him, not wanting to discourage classmates Kudo's detective enthusiasm: "I don't understand, I just saw that it was destined and wanted to take it out."
