Throw the Bottle

Ning Shu took the notebook and looked at it in disbelief, "Wow, you actually drew a map of Southeast Asia and the Pacific Ocean from memory!"

Jiang Yao was also surprised, "Xiao Zhe, I didn't know you had this kind of ability!"

Tang Xiaoguo was very indifferent, "What's so difficult about this, just scribbling randomly, I can do it too!"

Jiang Yao laughed, "Fruit, you probably drew that on the bedsheet!"

Lin Qianqian carefully distinguished, "The geographical locations and surrounding countries are all drawn very accurately! Lu Zhe, how did you do it?"

Lu Zhe of course would not tell them that this was copied from the map provided by the system in his mind.

"I was quite interested in geography in high school!"

Ning Shu thought for a moment, "This latitude should be between 15 and 30 degrees, further south than the Philippines!"

Jiang Yao said, "Then with the latitude, how do we calculate the longitude?"

"Simple!" Lu Zhe drew another vertical line on the map, "Based on the flight path between Pudong Airport and Kingsford Smith Airport, if we draw a line connecting them and intersect it with the latitude, we can figure out our approximate location!"

As he spoke, he drew a small circle at the intersection of the two lines.

"Congratulations, host, for accurately judging the approximate location, +1 potential point!"

Sure enough!

The four girls looked at it, "Where is this?"

"To the west is the Philippines, to the east is Palau and Micronesia, to the south is Indonesia, and to the northeast are the Mariana Islands."

Jiang Yao said, "So the black box really could have fallen into the Mariana Trench!"

Ning Shu asked, "Then which country's territory does it specifically belong to?"

Lu Zhe shook his head, "Unclear, most likely in international waters, but we can be sure that it is definitely not within China's jurisdiction."

Hearing this news, the girls were extremely disappointed!

Tang Xiaoguo sighed, "No wonder the rescue uncles didn't find us, turns out we got stranded out here!"

"Yeah! Based on the edge of this circle, we could be over 800 km away from any country."

Tang Xiaoguo thought for a moment, "800 km? Doesn't seem that far!"

Lu Zhe nodded, "Right, it's not far, about the same as the distance from our capital to Seoul!"

The numbers didn't make much of an impression on the girls, but as soon as a place name was mentioned, the sense of distance immediately came through!

Their little faces turned ghastly pale, "So terrible??"

"There's one more thing I don't understand!" Lin Qianqian thought for a moment, "Since we're in the tropics, it shouldn't be so cold even at night!"

Lu Zhe nodded, "Normally it shouldn't be very cold, but if at the confluence of cold and warm currents, this situation can occur!"

Jiang Yao was curious, "There are cold currents in the tropics too?"

"Of course there are!"

Lu Zhe nodded, "I'm guessing it's where the southbound Kuril Cold Current reaching the Philippines splits into two, and a small branch of cold current flows here, converging with the north equatorial warm current to form the phenomenon of large day-night temperature differences!"

Hearing Lu Zhe's explanation, Lin Qianqian suddenly understood, "I remember now, I read about it in world geography, the Galapagos Islands off South America are like this, where the southbound Peru Cold Current converges with the northbound Equatorial Warm Current, causing huge day-night temperature differences on those islands in the tropics, with both tropical jungles and penguin habitats!"

Jiang Yao exclaimed, "Penguins? Isn't that too exaggerated?"

Lu Zhe nodded, "Compared to the Galapagos Islands, the warm current here is stronger and the cold current weaker, so it's not as cold, but compared to other tropical islands, the day-night temperature difference here is still too big."

Lu Zhe figured out where he was stranded and got a reward from the system!

But he couldn't feel happy at all.

Just as the girls were worried,

Not being in China's territory meant that the country's search and rescue teams would need to go through complicated procedures and restrictions to enter territorial waters, greatly reducing the chances of being found!

Moreover, in this vast expanse of ocean, there were nearly a thousand large and small islands!

They didn't even know which island they were on themselves, so even if the rescue team had all the procedures in order,

Could they search every small island?

Tang Xiaoguo said in a crying tone, "So...we won't be found after all...right..."

Lu Zhe comforted, "Where there are people, there is hope. Don't lose heart everyone! We can send information to the rescue team through our own methods!"

The four girls looked at each other, all with confused expressions!

Jiang Yao asked, "We know, but how do we do it specifically?"

"The most primitive method!"

Lu Zhe shook a bottle, "Let's make message bottles!"

"Message bottles??"

The four girls looked at each other again, all with sudden realization:

"That's right, we can pick up lots of trash bottles on the beach!"

"We also have notebooks to write notes and put in them!"

"More importantly, we can mark our approximate location on them!"

"So it can increase the chances of being found!"

"What a great idea, how did I not think of that!"

"Xiao Zhe, you're so smart!"

Facing the girls' praise, Lu Zhe nodded deeply in agreement.

For message bottles, the most important thing was the bottle!

It had to be sturdy, sealed well, so it could drift across the ocean and reach land!

Since they also needed bottles for survival, and they didn't have too many bottles on hand now, in the end they set aside three relatively clean ones!

Lin Qianqian copied the map Lu Zhe drew three times, and marked their estimated crash site with an SOS symbol!

She also wrote down their number of people, names, and other important stranded information in Chinese and English! When the notes were written, Lin Qianqian handed them to Lu Zhe, "Help me take a look, anything else that needs to be marked?"

Lu Zhe looked them over. Lin Qianqian had already written very detailed information, but there was still one important piece missing: "Qianqian, add one more piece of information: today is June 10th, the sun set at 6:30 last night, and rose at 5:45 this morning!"

"With the date and the precise times of sunrise and sunset!" Lin Qianqian nodded, "This information will be more helpful for the rescue team to accurately determine our location!"

Lu Zhe nodded, "That's right!"

Lin Qianqian added the times of sunrise and sunset according to what Lu Zhe said in all three notes!

"Then...should we throw the message bottles now?"

"It's high tide now, if we throw them out they'll just wash back in! Let's wait until low tide, then throw them! Of course, they could still wash back in, but there's also a chance they'll enter the ocean currents and drift to some part of the world!"

Lin Qianqian nodded, "Okay, got it!"
