Stay away from Conan.

It seems that Xiao Ai deliberately waited until Yueshui Nanatsuki left, and Xiao Ai took the initiative to say this.

"what?"

Regarding this, Gao Yuan couldn't help feeling a little surprised and looked down at Xiao Ai, and asked in surprise——

After all, today, Xiao Ai and himself and Yue Shui Nanatsuki acted together the whole time. Why didn't he and Yue Shui Nanatsuki discover anything special, but Xiao Ai did?
"Huh? Didn't you and that lady notice? On this island, there are mudskippers."

Seeing Gao Yuan's puzzled expression, Xiao Ai seemed to be very proud and said.

"Mudskipper?"

Listening to this term, Gao Yuan knew the name of this fish, but he didn't know more about it, and he didn't even know what this fish looked like, so let alone what it meant for the existence of this fish on the island it's -

"The mudskipper is distributed in the Northwest Pacific Ocean, and it is only found in the southern part of Japan. It is not a widely distributed fish."

Xiao Ai smiled lightly and explained:
"And according to the geographical division of this fish, it can be indirectly proved that the Japanese archipelago may have been connected to the next-door continent."

"This……"

The corners of his eyes twitched, and when he heard Xiao Ai talking about such a thing, Gao Yuan couldn't help but helplessly support his forehead and said:

"How many years ago was it? Is it related to what we are currently investigating?"

"It must have been during the Ice Age."

Xiao Ai continued:

"At that time, some rivers flowed from the mainland to the Japanese archipelago, and the mudskipper may have used the river to flow to the Japanese area at that time."

"so what?"

Hearing this, he still couldn't understand the meaning of the little sad words at all, so Gao Yuan could only continue to ask.

Regarding this, seeing that Gao Yuan still couldn't understand what he meant, Xiao Ai seemed to be more satisfied, and said with a slightly raised corner of his mouth:
"Ah? You still don't understand? According to your previous discussion, because you feel that the manpower needed to build such underwater monuments is simply not enough for the residents of the island, right? But if you think about it differently, in the past, islands and Maybe a large number of people came to this island when the mainland was connected!"

"did you mean……"

At this moment, when it came to this point, Gao Yuan finally understood Xiao Ai's meaning, but he still felt a little shocked and said:

"I think the underwater ruins found on this island may really be man-made! But... that time is too early, isn't it? Prehistoric civilization..."

"Prehistoric civilizations built large-scale facilities, didn't they?"

Xiao Ai said:

"Also, I just provided an idea."

"That's it."

Nodding slightly, Gao Yuan replied in this way, feeling that the idea provided by Xiao Ai is not impossible, so he thought about it and said:

"If the underwater monument is really a man-made building, no matter how simple the construction is, then there should be space inside... So, the treasure mentioned in the legend..."

Speaking of this, Gao Yuan's thoughts suddenly froze, and then his expression became serious:

"If it is really confirmed that the ruins are real, then...the missing tourist, Hattori Heiji in distress..."

At this moment, Gao Yuan, who was originally just some conjectures, began to seriously consider a certain possibility——

Although it is said that the investigation of the underwater ruins and the incident of finding out the missing tourists should be two different things, but if the underwater ruins are really man-made structures, perhaps the two incidents are actually related!

For example, on this island, there are really some people who are sure that the underwater ruins are real and have discovered the secrets of the underwater ruins, so in order to monopolize the legendary treasure, that person will send those who almost discover the truth of the underwater ruins, One by one was dealt with, and thus there was an incident of missing tourists.

And if you think about it this way, it is even more likely that Hattori Heiji's encounter today was not an accident!
At the beginning, I thought about it. I and others are here to investigate the underwater ruins, so the idea is to prove the authenticity of the underwater ruins. In terms of rationality, based on Hattori Heiji's observations, I and others feel that the ruins are There is a high possibility that it is a simple rock.

But if some people believed that the ruins were real from the beginning, what would they think?

Thinking of this, Gao Yuan immediately set off and rushed towards Mr. Xiao Bin's diving equipment rental shop by the pier——

Some things may be answered there.

Therefore, after seeing such a big change in Gao Yuan's attitude in a short period of time, Xiao Ai nodded proudly, feeling that what she said just now seemed to have really helped Gao Yuan a lot.

As a result, Xiao Ai was a little proud, and followed Gao Yuan's footsteps, walking towards the diving shop on the island——

"Is Mr. Xiaobin here?"

And when Gao Yuan came to the diving shop and looked at the unlocked shop door, after Gao Yuan opened the door and looked at the lobby inside the shop, only the Miss Xinyuan who he had seen today was there, Gao Yuan asked asked the other party whether Mr. Obama is in the store.

In this regard, the Miss Xinyuan who seemed to be fiddling with something on the table didn't seem to want to move when she heard someone came to the store. The Miss Xinyuan said without even turning her head:
"It's too late today, and we don't rent out diving equipment."

"No, I'm here to ask Mr. Xiaobin about something, not to rent diving equipment."

Seeing that the other party seemed to be busy, Gao Yuan didn't rush to urge her, but he still explained his intention to her seriously, hoping to know the whereabouts of Mr. Xiao Bin.

"Mr. Xiaobin has gone out, I don't know where he went."

And Miss Aragaki still didn't look up, just responded like this.

"Is that so..."

Knowing this situation, Gao Yuan couldn't help being a little surprised, but looking at the lady in front of him, thinking about the morning, when he heard Junya Tokitsu say that the other party seemed to be in the store when there were many tourists on the island. He seemed to be helping, so he also tried, and asked the other party a question:
"Then since Mr. Xiaohama is not here...Miss Aragaki, I don't know if you are clear about one thing. Didn't the island disappear before three tourists? Did the three tourists come to rent diving equipment before? And in the process of diving, did you encounter any situation?"

With that said, Gao Yuan walked a little closer, came to Miss Xin Yuan's side, and asked in a friendly manner.

However, at this moment, after Gao Yuan approached Miss Xinyuan, he finally saw clearly what this Miss Xinyuan, who didn't even look back when she spoke, was busy with——

"Aeromodelling?"

Looking at the parts on the table, Gao Yuan recognized what they were at a glance.

Obviously, when these parts are assembled, it is an aircraft model, and it is obviously a real simulation model with a power system, which should be able to take off by remote control.

So, seeing that the other party seems to be fascinated by the assembly of model airplanes, Gao Yuan thought whether to use this as a topic to get close to the other party, a thought suddenly flashed through Gao Yuan's mind——

"When the eyes are higher than the giants, the three giants are combined into one... Is it possible that the secret of the so-called 'Giant Rock' refers to..."
