It is difficult to estimate the amount of energy consumed by trekking for several hours in the snow.
After Shi Yu said that, he didn't care whether the two people present agreed or not, and curled himself up in the quilt.
Ji Congyang stood there for a few seconds, then stood up quietly, walked to the door, exchanged a glance with Qiao Yan, and left the room one after another.
The moon outside the window tilted from the center to one side and fell into the sea level, with the sun rising and the moon setting.
Shi Yu opened his eyes from his coma, stared at the wall of the room for a few seconds, then lifted the quilt and sat up.
Fortunately, as mentioned before, he didn't stay in the snowfield for too long, and he was sent here in time. Although his skin was still painful from frostbite when he first woke up, now apart from a little dizziness in the head, there is basically no problem.
After leaving the room, the medical staff on duty looked over and greeted him.
Shi Yu had just pushed open the door of the infirmary when he ran into the person coming in.
Ji Congyang had an apple in his mouth. When he opened his mouth subconsciously, the apple almost fell out. He quickly caught it: "Are you awake? Are you going out?"
Shi Yu nodded.
There is no heating in the corridor, and although the temperature is not as extreme as in the snow, it is indeed close to zero degrees Celsius, which is just enough to ensure that the sea water under your feet does not freeze and the cruise ship can operate normally.
He glanced at his thin sleeves and asked, "Is there any vacant room on this ship?"
"Yes!" Ji Congyang replied reflexively, and then hurriedly made amends, "Wait a minute, I'll go to the front desk to ask for you, and I'll be back soon!"
After saying that, he didn't even wait for an answer and ran away like the wind.
Twenty minutes later, Shi Yu received the reissued boat ticket and distributed room keys.
"You need more clothes, right? I'll go to the duty-free shop and buy them for you!" Ji Congyang had just led the person to the room when he ran away.
There are only a few types of clothing for sale on cruise ships, and even fewer casual items. When the items were finally delivered to me, the labels weren't even removed.
Shi Yu used a fruit knife to remove all the tags on her clothes and threw them into the washing machine, waiting for them to dry before putting them on.
Ji Congyang finished eating an apple in the living room, ate two packs of biscuits and drank a box of juice. Then he came out with his hair still dripping.
He recalled the other person's performance in the previous few games and found that the one he was a fan of was really clean, otherwise he would not have to wash up whenever he had the chance, no matter if he was sick or injured.
But the amazing thing was that when he was really in a situation where he was covered in blood and mud, the other party was not like those mysophobes he had seen in the past who could not tolerate any dirt at all. On the contrary, he adapted quite well.
What is this?
Ji Congyang was peeling an orange while thinking, and he always felt that his idol had many secrets.
Shi Yu was looking at the sea below the boat.
Because the weather is cold, the salty smell in the sea breeze is not obvious, and when looking down, you can only see the undercurrent below from the surface.
He thought of the snowy field where he was before he came here, and his eyelashes half drooped.
One is on the sea and the other is on the snow.
Is it random, or is there some connection that has not yet been discovered?
After thinking for a moment, he went back into the room and closed the French window.
The room on the cruise ship was the most luxurious. There were some fruit snacks scattered on the plate on the table. Ji Congyang had almost finished them in a short while.
Shi Yu and the pile of fruit peels and packaging bags on the table were silent for a while, and finally left a sentence: "Remember to throw it in the trash can."
Ji Congyang looked at the table and felt a little embarrassed for the first time: "I'll clean it up right away."
He was shoveling trash in the trash can, and seeing the other person about to enter the room again, he asked, "Aren't you going to the restaurant to eat?"
Shi Yu looked up at the clock and asked, "Is the restaurant still open at this time?"
"As long as you have the money." Ji Congyang said as he walked to the door and waved at him, "I'll take you there!"
※
Qiao Yan, who had been missing for a whole morning, appeared at the dining table, glanced at the two people at the table, and kicked the foot of the stool: "Go in."
Ji Congyang moved the fruit plate in front of him and everyone else to the empty seat by the window.
Qiao Yan sat down at his seat and took out a sea map: "The control room of this ship is at the bow of the third underground floor."
"Is there someone guarding it?"
"There are no less than ten staff members who have to pass through here." Qiao Yan took out the compass again, "There are a total of eight crew members stationed inside, not including those who may come in and out at any time."
"What's the big deal?" Ji Congyang was peeling melon seeds attentively. "Who can beat your speed when you put on ice skates? Can these ten people stop you?"
Qiao Yan did not comment, took out a pen and circled the Nansha Sea area on the map: "When the cruise ship moves forward, the compass angle will be slightly skewed."
He adjusted the pointer and watched the red end stop. He turned the dial to be parallel to the small arrow on the map. "After sailing for a period of time, the pointer will deflect back to its original angle. This large deflection should be because the cruise ship reached the boundary of this space and then returned from the other end of the space."
Ji Congyang stopped peeling melon seeds and blinked blankly: "...Ah."
Qiao Yan casually drew a line in the circle, paused the pen tip at the midpoint of the line segment, and drew a vertical line: "I can roughly estimate the direction the cruise ship needs to change next, but I don't know how far it will go. During this period of time, I'm afraid I have to be careful of the crew on the ship to manipulate it."
Ji Congyang was stunned as he watched from the side: "Wait a minute, why can you be sure of this?"
"With the South Pole as a vertex of the triangle, the speed and time of the cruise as one side of the triangle, and the compass as three angles, we can determine the direction and distance between the segment of our journey and the South Pole." Qiao Yan wrote quickly on the map. "Didn't your idol say before that this space can be seen as a closed circle? Although I don't know the radius of this circle for now, as long as the cruise ship reaches the midpoint of the chord in the circle and directly turns the course 90 degrees, the direction line will definitely pass through the center of the circle."
When Ji Congyang looked at the lines on the map, his mind was in a mess.
Qiao Yan didn't wait for him to catch up with his thoughts: "But there is still a big problem with this."
Ji Congyang: "...Ah?"
Shi Yu: “Direction.”
Ji Congyang: "...Ah?"
Qiao Yan nodded: "Even if it turns 90 degrees, we don't know whether it should turn clockwise or counterclockwise, because there is only one known length of the chord, and we can't determine on which side of the chord the center of the circle is."
Shi Yu: "What is the speed of the cruise ship?"
Qiao Yan twirled the pen and looked at him: "Fourteen knots per hour."
"Compass deflection time?"
"About ninety minutes."
Shi Yu lowered his eyes and remained silent for a moment, then said, "Turn north, twenty-six nautical miles."
Qiao Yan tapped the tip of his pen on the paper, leaving a dot of ink: "Why is it 26 nautical miles?"
Shi Yu lowered his head and drank a mouthful of soup: "In the closed space I was in before, the length of the space radius would take me about two hours to walk at my speed."
"The radius of that space is ten kilometers?"
“It’s all snow there.”
Qiao Yan was stunned for a few seconds, then understood: because the snowfield environment is too extreme, the speed of humans in it cannot be measured by normal human walking speed. People with good physical fitness can walk ten kilometers in two hours in reality, but in that environment, they may not even walk one kilometer.
He brought the topic back to where it had gone off track: "So you want to use your space as an analogy? But the diameters of the two spaces are obviously too different."
"This is a game." Shi Yu said, "The system puts players here in the hope that they can complete the mission. It is impossible for people to be delayed for too long in a certain place due to objective reasons. Therefore, the time it takes for players to reach the exit of the closed space from any point in the closed space should not vary too much."
"Since the two places are not equal in size, we will enlarge them in proportion to the player's speed, and the time required will remain unchanged. Assuming that this closed space takes two hours to travel at the original speed of the cruise ship, the radius is 28 nautical miles. The distance from the middle point of the current journey to the center of the circle is about 26 nautical miles."
Qiao Yan asked again: "Then why do we have to go north of the string line?"
"It's just a guess." Shi Yu said, "Assuming it takes two hours to get from the circumference to the center, that's 28 knots. If we go into the control room and speed up the cruise ship, we can shorten the journey to one hour. If the cost of making a mistake is not high, we can turn around in time."
"I'll go straight to the control room later," Qiao Yan put down his pen, "Do you plan to stay on this ship?"
"You don't plan to take him with you?"
"When the cruise ship reaches the center of this circle, his position on the ship will overlap with the center of the circle, and he will be automatically sent out. There is no need for him to come with me."
Shi Yu raised her eyelashes slightly: "If you don't want to be separated from him, my suggestion is to take him with you."
Qiao Yan paused.
Shi Yu: "The control room is at the bow of the ship on the third underground floor, and the restaurant is at the stern. Even without considering the height difference between the two places, the horizontal distance alone is dozens of meters. If you want to drive the cruise ship to the center of the closed space, when the deck you are standing on overlaps with the center of the circle and you are sent out of this space, there will be a long time difference between you and him reaching the center of the circle."
Once there is a time difference, if two people leave this closed space one after the other, it is hard to say whether they will be sent together after going out.
They must reach the center of the circle at the same time.
Qiao Yan stopped and frowned: "If it's just because of the time difference, it would still happen even if we were standing together now."
"That's at least smaller than a bow and a stern, and can be ignored during navigation." Shi Yu said calmly, using declarative sentences, "You should be even less willing to take risks."
Qiao Yan did not deny it: "I'll think of a way, thank you."
Shi Yu shook his head: "It's to repay his favor."
After all, Ji Congyang had been busy with him all morning.
The two of them fell silent.
Ji Congyang looked at this and that, then picked up the melon seeds on the table and swallowed them with mixed feelings.
【Seeing Ji Congyang's expression, I was sure that I wasn't the only one who didn't understand what they were saying. 】
[I thought it was abnormal enough that Shi Meiren used her own steps in the snow to measure the size of a closed space, but now there is another one? Why does it feel like the whole world knows how to deduce the scope of an entire area based on a few numbers, but I don't? ]
[Based on the ship's cycle in a closed space, the distance and position of the center of the space circle can be deduced by geometric method. If you tell me the method, I can understand the principle, but if you let me think about it myself, I am afraid I will never figure it out. These two people react too quickly, what's wrong with their brains? ]
[The worst part is that this group game has only been going on for less than a day and it’s already like this. What are we going to do next?]
[There is no need to worry about others. At least, no matter how unsolvable the current situation is from our perspective, it will not affect their success. Just focus on watching the live broadcast. ]
[In the end, did they decide to leave this space? I thought they were going to stay alive here and decided to give up watching other players' split screens. Now I'll just stay and observe for a while. ]
[Don't forget that if you want to get to the control room, you have to find a way to deal with nearly 20 professionally trained, strong and armed crew members, and gain control of the cruise ship for at least two hours. Whether you can get out is another matter.]
[So, this is the start of the group? ]
