"Maybe it's an echo." Wei Qingyun forcibly explained.

"Echo?" Sun Zhongwen asked.

Sun Meiru didn't listen to Wei Qingyun continue, and shook her head impatiently.

"Yes, the sound can travel far away, maybe it is the sound of birds and beasts from the Ryukyu Islands or the island of Taiwan, this island is full of valleys and gorges, if the conditions are right, those originally distorted sound waves will come out clearly again."

“……”

"Don't believe me? I used to like to climb mountains, and I often heard the sounds of the market and the cries of cattle and sheep in the valley, very clearly, as if someone was talking around me, but those sounds did not happen in the valley at all, and I don't know where they came from. ”

Wei Qingyun was giggling, and people couldn't tell whether he was saying this to liven up the atmosphere or be serious.

It wasn't until they were hungry and drank all the water they brought that the four of them returned in vain.

Back at the offshore platform, it was already past two o'clock in the afternoon. Sun Yaoru insisted that they have lunch and then discuss work.

After listening to the statements of the four people, as well as the few thermal photos taken by Sun Meiru, the reactions of Sun Yaoru and several people seemed too calm.

"What? If there is no response, is it because our story is not exciting enough? Wei Qingyun joked.

"It's not that your story isn't exciting, it's that our discovery is more terrifying." Xie Lingyan glanced at Wei Qingyun, pointed to a technician beside her, and made an exaggerated grimace.

Just when Wei Qingyun and his group were inspecting B-03 Island, Sun Yaoru commanded on the spot, using drones equipped with ultrasonic and sonar technology to survey the entire island chain and establish a complete holographic 3D model.

They also discovered what Sun said, with strong, mixed sound waves filling the entire island with no matching fauna.

There are only a few birds, lizards, rats, etc., which are too far from the huge number of sounds, and the sounds of several animals, such as wild boars, badgers, and antelopes, are not found on the island at all.

Not only that, but they also discovered a huge cavity – something that resembles a cave.

The technician zoomed in on part of the 3D model and pointed out that part of the project, which was where the drone had an accident. There is a "cavity" nearly thirty meters high and three square kilometers in size. ”

When the technician introduced, he emphasized that it was a cavity, not a cave or a cave.

Because this "cavity" is not in the belly of an island at all - it exists above a sea, in the "air".

This cavity was discovered by ultrasonic oscillation.

Sun Yaoru realized the strangeness of the matter, and immediately ordered people to use satellite photography and ultrasonic frequency to make a 3D map of the sea area where the entire island chain is located.

By comparison, it is found that the whole map of the island drawn by ultrasonic frequency technology is nearly ten times larger than the whole map of the island drawn by satellite photography.

In other words, there is an island in that sea that we cannot see.

Wei Qingyun and the four of them were shocked when they heard this, they were the ones who actually crossed the island, if there really were so-called islands and spaces that were not yet seen, in what form did they exist?

Even if it's invisible, the body can't be hidden, they sailed through that sea area, and they have been on the island for so long, if something invisible exists, they should also collide.

Things are getting more and more unbelievable. It's completely beyond people's perception of space.

The atmosphere in the command room was a little low, and Sun Yaoru smiled and comforted everyone in order to break the lifeless situation, and asked everyone what they thought about this matter.

"Let's talk about it, I'm not an expert in physics, and I don't know much about this special space, so you can just say it, and you may be able to find the right answer."

"Mr. Sun," one of the technicians said, raising his hand, "are we going in the wrong direction, why are we dwelling on this issue, aren't we here for the Rising Sun Maru?" ”

"yes, this place is weird, but it doesn't have anything to do with our goals?"

What these two people said is not unreasonable.

In many cases, the immediate difficulties are not necessarily related to our real goals.

They just waste our time and energy and drag us away from the right direction.

Most of the crew and technicians held this view, and there was a lot of discussion for a while, and the command room suddenly became lively.

More and more people tend to search for islands and straits, and if they can't find the ship, they expand the scope and search the bottom of the sea.

It's been almost a hundred years, and no matter how strong the ship is floating on the sea, without any maintenance measures, the rain and wind blow, even if it is not rotten, it will sink early, not to mention that there have been so many large tsunamis, the ship will definitely not be able to bear it.

Sun Yaoru glanced at Sun Meiru, since he came back from the island, he has been frowning and worried.

Sun Yaoru looked at him and opened his mouth, wanting to say a few words to ease his dull mood, but he lowered his head and avoided his gaze, secretly saddened there.

Wei Qingyun insisted on continuing to investigate the island, especially in the vicinity of B-03.

Because there are many secrets involved, and there are many Japanese employees on the ship, Wei Qingyun didn't expand too much, but said that about Yamamoto Kiichi, his life is a huge mystery, and many things about him are beyond common sense.

Therefore, if you want to find the Rising Sun Pill, you must also dare to break the rules, and the more eccentric the place, the more likely it is that the Rising Sun Pill is hiding.

"Hey, yes, I've heard for a long time that the founder of the Yamamoto Foundation is a weird guy, and among the rich, he lives like a hermit, and now there are many Internet reporters who dig up his life as a hype gimmick."

"Oh, too, hey, I've read that post too, there is a guy who picks up the weird old man, and often goes to a sushi restaurant called Jiro to eat sushi, and the owner of the shop also took out a photo of his grandfather and the weird old man."

"No, some people questioned that the photo was fake, it was PS, and the store bought the online reporter to hype."

"Hey, anyway, it means that the old man is a weirdo."

"Yes," Wei Qingyun took the opportunity to interject, "This Yamamoto Kiichi is not only a geek, but also a biological genius, a language genius, can speak several foreign languages, and is a very smart and eccentric person. ”

"Oh, a clever and eccentric fellow, so he probably discovered the secret of this place decades ago and hid the ship in that unseen place?" A guy suddenly said.

"Yes, so that weird place, you still can't give up, but I agree with you, you shouldn't just stare at it, and you should also look for the bottom of the sea."

Wei Qingyun reversed public opinion, although the words of these crew members are reasonable, but there is also a large component of escaping the unknown danger.

They must be encouraged and, if necessary, fooled.

"Tonight, continue to monitor there tonight, and send drones over to take a look." Sun Meiru, who had always refused to speak out, suddenly chattered.

He looked tired and in a trance, and after he finished speaking, he turned around and left without saying hello.

Wei Qingyun glanced at him, guessing that he might not have slept all night last night, and he followed the island to run around today, so he should be tired.

Sun Yaoru signaled that everyone didn't have to disturb him, and let him rest. I arranged the next work by myself.

Divided into two teams, one team remotely controls three deep submersibles to patrol the seabed.

This sea area is not deep, only about 2,000 meters, but the situation is unknown, and personnel are temporarily prohibited from entering the water, and the submarine that originally went deep into the bottom of the sea also returned and docked at the offshore platform.

The second team continued to control the UAV and used electromagnetic induction, ultrasonic, thermal imaging and other technologies to conduct 24-hour monitoring of the B-03 island area.

Wei Qingyun and Xie Lingyan came out of the command room, only to find that the sky was almost dusk, the red sun was like a torch, and the sky and sea illuminated were dazzling golden.

"Wei Qingyun, I'm homesick." Xie Lingyan turned her back to the sunset and leaned against the railing.

"Huh?" Wei Qingyun squinted at her, not quite understanding what she meant.

"Ahh

“……”

"Haven't you ever thought about getting married?"

"Married? Where to get married? I'm a wanted criminal, and as soon as I sign up for the Civil Affairs Bureau, I won't be arrested immediately. ”

"Hey, I said you, this is all a reason for you to refuse to get married."

The two of them talked and laughed, and soon it was time for dinner.

The morale was low first. In order to liven up the atmosphere, Sun Yaoru changed the dinner into a party, these people are used to the sea, all of them have a good talent, singing, talking cross talk, magic, all kinds of things, so lively.

The food was also plentiful, with a lot of freshly caught fish and crabs and a few large lobsters.

In such a scene, everyone left their work troubles behind and enjoyed eating, drinking and having fun.

At this moment, a seafarer suddenly broke in in a panic and turned off the power of the audio equipment, and the air suddenly froze.

"Captain Sun is gone, Captain Sun is gone, there is no one in the dormitory, he can't be found anywhere, and the boat that went to sea in the morning is gone."

The Captain Sun he is talking about is Sun Meiru.
