Su Huilan and Aoki were a little excited, if Ivan and Boris appeared on the island, then it was likely that Situ was also there, and even the entire expedition team was on the island.

Aoki asked, "How far are we from where the wreck of the research ship was found?" ”

He didn't do much research on ocean currents and sea search and rescue, but he had a clear idea, and both Su Huilan and Petru knew about it, especially Petru, whose home was the ocean.

Petru understood what he meant, and immediately checked the current specific location through the GPS system, and at the same time opened the navigation chart and asked them where the wreck of the research ship was found.

However, to his surprise, he suddenly found that the GPS system was out of order and could not find any signal. He turned on the other communication equipment on the ship, how could a great pirate like him not have advanced equipment on his ship? But the problem is that no set of devices can be connected to satellites in the sky.

"What the!" Petru slapped the instruments in the cab hard, "Did we enter some radio blind spot?" I can't get any signal! ”

Su Huilan also took out a small signal receiver from her box and connected it to her PAD, and the result was the same.

Aoki looked at the fog ahead and remembered what happened to the research ship: "It must be the relationship between these fogs." ”

Su Huilan nodded and said, "We may have fallen into some spatial bubble. ”

"Space bubbles?" Petru had heard Su Huilan talk about those three-dimensional and two-dimensional conjectures, and these nonsense scientific knowledge was even more terrifying to his ears than hearing the legend of the sea monster, "So what now?" To the island or to retreat? Do you want to wait for the fog to clear? ”

Su Huilan said: "It is estimated that it is too late to retreat, and it is impossible for us to find this island in fog-free weather, do you think about it last time when it was foggy?" ”

Petru nodded: "That's true. ”

Aoki said, "Didn't you always have the location of this island, and you didn't notice that the GPS was out of order before?" ”

"I didn't pay attention, although the GPS was always on, I drove the boat by feeling a lot," Petrux said. You know it's dangerous for a pirate to run away with GPS, people like us can travel the world with a chart. As for here, I found it according to those sheepskin charts, and later after leaving the island, I checked the positioning, and the GPS was good at that time, but it was far away from the island, and I calculated the location of the island according to the ship's route and speed, which is basically the same as the mark on the chart, and I think our current position will not deviate to any point. ”

Aoki said: "Well, then according to the position on your chart, you know more about maritime affairs, and calculate whether it is possible for the people on board to drift here after the wreck of the research ship." ”

Su Huilan operates directly on her PAD, which has a map software inside. She shifted the map to the area where they were now located, and pointed her finger at the location where the wreck of the research ship had been found, an uninhabited reef southwest of the Bass Islands, just south of the Tubuai Islands.

Then she marked two points on the map according to the old charts and the locations that Petru had mapped, and asked Petru: "This is where we are now, this is the position of the triangle on the chart, right?" ”

Petru looked at the coordinates displayed on the PAD: "That's right. ”

Su Huilan got Petru's confirmation, and after a few more operations, a straight line was connected between the three points, and a circle appeared in the center of the circle with the position of the triangle, and the other two points fell within this circle. Then, there were some color changes of warm yellow and warm red in the originally blue sea area throughout the circle.

Aoki didn't know what kind of map software this was, he thought it was very advanced, and guessed that it was some kind of software for military or scientific research, but he didn't know why Su Huilan, a philosophy professor, would understand these things. But he can't even solve the mystery of himself, so he doesn't think much about other people's affairs.

Su Huilan pointed to the center of the circle on the map and said: "Judging from the target of the research ship and the description of Captain Church's diary, the area where the accident occurred should be the location of the seabed ruins, that is, the triangle marked on the chart, near the intersection of 30°S latitude and 150°W longitude." ”

She pointed to another point, "This is where the wreckage was first found, about two hundred nautical miles from the accident site. This is where we are now, about 150 nautical miles from the site of the accident. But the two places are far apart, about four hundred nautical miles. Petru, in your experience, the ship had an accident in this location, and the wreckage and drift was not possible to drift to both places at the same time. ”

"It's hard to say, you have to take into account ocean currents, monsoons and all kinds of possible weather effects, but also calculate the time, you give me too little information," Petru said. ”

Su Huilan pointed to the changing colors on the map and said, "This is a simulation of the monsoon and ocean currents in this area for nearly half a year, and the data I just obtained from the US Weather Service before I came. Red and yellow are current changes, and white is larger-scale cloud changes, including tropical cyclones and storms. ”

"Oh, what software are you? That's great! Can you get one on my boat too? Petru exclaimed.

"If this mission is over and we are all alive, I'll help you get Lavier out of the Egyptian prison, and if you still want to be a pirate at that time, I'll pretend to be one for you." Su Huilan said, "But let me tell you, this thing was made by the U.S. Navy." ”

"Oh, forget it, then." Petru immediately said, "This alone is not enough, I also need to know the course and time of the ship you are talking about." ”

Su Huilan said: "The specific route is not clear, more than half a year has passed since the scientific research ship was lost, but we later received a brief radio wave from them, and the time and location of its accident can be roughly determined. ”

"According to the captain's diary, the last thing that happened was Christmas Day." Aoki added.

"Christmas ......," Petru said after staring carefully at the climate change displayed on the PAD, "judging from my experience, there is no problem with the location of the shipwreck, and I think you should have found more drift." ”

Su Huilan nodded and said, "But no body was found." ”

"It's normal." "It's two hundred nautical miles from the sea where the accident occurred, and the currents here are less than two knots, and they don't go in a straight line, which means that the drifters may have to drift at sea for seven or eight days to get there, and by the time you find them, more than half a month has passed, and if there were corpses, they might have been eaten by sharks or something." ”

"Is it possible that they will come here?" Aoki asked.

Petru shook his head and said, "Unless they have a lifeboat, or like Professor Su said, this is a space bubble, and since it's a bubble, then who the fuck knows if he's floating around!" ”
