God does not love the world [unlimited]

Trekking for hours in the snow is hard to fathom.

After Shi Yu said that sentence, he didn't care whether the two people present agreed or not, and shrank himself into the quilt.

Ji Congyang froze for a few seconds, stood up lightly, walked to the door, exchanged glances with Qiao Yan, and left the room one after another.

The moon outside the window slanted from the center to one side, fell below the sea level, and the sun rose and the moon set.

Shi Yu opened her eyes from the drowsiness, stared blankly at the wall of the room for a few seconds, lifted the quilt and sat up.

Fortunately, as I said before, he didn't stay in the snowfield for too long, and he was sent in time. When he woke up for the first time, his skin still had frostbite pain, but now he was a little dizzy except for his head. It's all right.

Leaving the room, the medical staff on duty looked over and greeted him.

Shi Yu just pushed open the door of the infirmary when he bumped into someone.

Ji Congyang had an apple in his mouth, and when he saw him open his mouth subconsciously, the apple almost fell out of his mouth.He quickly caught it: "Are you awake? Are you going out?"

Shi Yu hummed.

There is no heating in the corridor. 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 run normally.

He glanced at the thin sleeves and asked, "Are there any vacant rooms on this ship?"

"Yes!" Ji Congyang replied reflexively, and hurried to remedy, "Wait, I'll go to the front desk to ask for you, and I'll be right back!"

Without waiting for an answer, he ran away like a gust of wind.

Ten minutes later, Shi Yu got the reissued ferry ticket and the key to the guest room distributed.

"I still have to add clothes, right? I'll go to the duty-free shop to buy them for you!" Ji Congyang led him to the room before running away.

There are few types of clothing sold on the cruise ship, even fewer casual ones, and the labels were not even torn off when the items were finally delivered.

Shi Yu used a fruit knife to remove all the clothes tags and threw them into the washing machine, and then replaced them after drying.

Ji Congyang finished eating apples in the living room, ate two packs of biscuits and drank a box of juice, and when he came out, his hair was still dripping.

He thought of the opponent's performance in the previous few games, and found that the one he was following really liked cleaning, otherwise he wouldn't have to wash up whenever he had the chance, no matter if he was sick or injured.

But what was amazing was that when it came to the bloody and muddy situation, the other party was not like the cleanliness he had seen in the past who couldn't bear a little dirt at all, on the contrary they adapted quite well.

what is this?

Ji Congyang peeled the oranges and pondered over and over again, always feeling that his idol had a lot of secrets.

Shi Yu was looking at the sea below the boat.

Because of the cold weather, the salty smell in the sea breeze is not obvious. When looking down, you can only see the dark tide underneath from the outermost layer.

He thought of the snow field he was in before he came, his eyelashes half drooping.

One is at sea and the other is in the snow.

Is it random, or is there some undiscovered connection between them?

After thinking for a moment, he entered the room again and closed the French windows.

The room on the cruise ship is the most upscale, and there are some scattered fruit and snacks on the plate on the table. Ji Congyang has almost solved it in such a short time.

Shi Yu and the pile of peel bags on the table were relatively silent for a while, and finally left a sentence: "Remember to throw it in the trash."

Ji Congyang looked at the table, feeling a little embarrassed for the first time: "I'll clean it up now."

He picked the pile of rubbish in the trash can again and again, seeing that the other party was about to enter the room again: "Aren't you planning to go to the restaurant for dinner?"

Shi Yu looked up at the wall clock: "The restaurant is still open at this point?"

"As long as you have money." Ji Congyang walked to the door of the room and waved to him, "I'll take you there!"

■

Qiao Yan, who had been missing all morning, appeared at the dining table, glanced at the two people on the table, and kicked the stool: "Go in."

Ji Congyang moved the fruit plate in front of him into the empty seat by the window together with others.

Qiao Yan sat down at his seat and took out a map of the sea area: "The control room of this ship is at the bow of the third floor underground."

"An guard?"

"There are no less than ten staff members passing by here." Qiao Yan took out the compass again, "There are a total of eight crew members stationed inside, not including those who may enter and exit at any time."

"What's the matter?" Ji Congyang concentrated on peeling melon seeds, "Who can beat your speed when you wear ice skates? Can these ten people stop you?"

Qiao Yan was noncommittal, took out a pen and circled the Nansha waters on the map: "When the cruise ship is moving forward, the angle of the compass will be slightly skewed."

He dialed the pointer, watched the red end stop, and turned the dial in a direction parallel to the small arrow on the map: "Every time you sail for a while, the pointer will deflect back to the original angle. This time the big deflection should be It was the cruise ship that went to the boundary in this space, and then came back from the other side of the space.”

Ji Congyang stopped peeling melon seeds, blinked blankly: "...ah."

Qiao Yan casually drew a line in that circle, the tip of the pen paused in the middle of the line segment, and drew a vertical line: "I can roughly estimate the direction that the cruise ship will need to change next, but I don't know how long it will take. , during this period of time, I am afraid that the staff on board should beware of manipulating it."

Ji Congyang was stunned watching from the side: "Wait a minute, why can this be confirmed?"

"Using one vertex of the South Pole triangle, one side of the triangle determined by the sailing speed and time, and three angles determined by the compass, we can determine the azimuth and distance from the South Pole to the current section of our journey." Qiao Yan moved his brush like flying on the map , "Didn't your idol say it before, this space can be regarded as a closed circle. Although I don't know the radius of this circle for the time being, as long as the cruise ship walks to the midpoint of the chord in the circle, directly set the course Turning [-] degrees, the direction straight line must pass through the center of the circle."

Looking at the lines on the map, Ji Congyang's mind became 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: "...Huh?"

Shi Yu: "Direction."

Ji Congyang: "...Huh??"

Qiao Yan nodded: "Even if it turns [-] degrees, I don't know whether it should be turned clockwise or counterclockwise, because there is only one chord length known so far, and it is impossible to determine which side of the chord the center of the circle is on."

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?"

"Nine ten minutes or so."

Shi Yu lowered his eyes and remained silent for a moment, then said, "North turn, 26 nautical miles."

Qiao Yan tapped the pen tip on the paper, and blurred out an ink dot: "Why is it 26 nautical miles?"

Shi Yu lowered his head and took a sip of the soup: "In the closed space I was in before, the length of the space radius would take 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 and understood: because the snowfield environment is too extreme, the speed of human beings in it cannot be measured by the normal walking speed of human beings.People with good physical fitness can walk ten kilometers in two hours in reality, but in that environment it is very likely that they can't even walk one kilometer.

He brought back the crooked topic: "So you want to use your space as an analogy? But the diameters of the two spaces are obviously too far apart."

"This is a game." Shi Yu said, "The system puts players here in the hope that the players will complete the task. It is impossible for people to be delayed for too long due to objective reasons, so the players have to catch up at any point in the closed space." The time to the exit of the closed space should not be much different."

"Since the size of the space between the two places is not equal, it will be scaled up according to the speed of the player, and the time required will remain the same. Suppose this closed space takes two hours to travel at the original speed of the cruise ship, and the radius is 28 nautical miles. The distance from the middle point to the center of the circle is about 26 nautical miles."

Qiao Yan asked again: "Then why did you go north of the string?"

"Guess." Shi Yu said, "Assuming that it takes two hours to reach 28 knots from the circumference to the center of the circle, if you enter the control room and speed up the cruise ship, you can completely shorten this distance to one hour. If you make a mistake, the cost is not high. You can turn back in time."

"I'll go directly to the control room later," Qiao Yan put down his pen, "Are you going to stay on this ship?"

"You didn't intend to take him with you in the past?"

"When the cruise ship reaches the center of the space, and his position on the ship overlaps with the center of the circle, he will be sent out automatically. There is no need to accompany me."

Shi Yu raised her eyelashes lightly: "If you don't want to be separated from him, my suggestion is to take him with you."

Joe hated making a move.

Shi Yu: "The control room is at the bow of the ship on the third floor underground, and the dining room is at the stern. Even if the height difference between the two places is not considered, the pure horizontal distance is tens of meters apart. The moment the deck you stepped on overlaps with the center of the circle and you are sent out of this space, there will be a long time lag between you and him reaching the center of the circle."

Once there is a time difference, the two leave this closed space one after the other, and it is hard to say whether they will be sent together after going out.

must reach the center of the circle at the same time.

Qiao Yan stopped and frowned slowly: "If it's just because of the time difference, even if we stand together now, there will be."

"That's at least smaller than the prow and stern of a ship, and it can be ignored during navigation." Shi Yu's tone was flat, using declarative sentences, "You should be even more afraid of taking risks."

Qiao Yan didn't 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 has been busy around him all morning.

The two fell silent.

Ji Congyang looked at this and then that, twisted up the melon seeds on the table with complicated emotions and swallowed them.

[Seeing Ji Congyang's expression, I'm sure I'm not the only one who can't understand what they're saying. 】

[I thought it was crazy enough for Shi Meiren to calculate the size of the closed space by her own steps in the snow, but now there is another one?Why does it feel like the whole world knows how to use a few numbers to deduce the scope of an entire area, but I don't? 】

[Just relying on the ship’s cycle in a closed space to deduce the azimuth and distance of the center of the space by geometric methods, I can understand the principle if you tell me the method, but if you let me think about it, I’m afraid I won’t be able to figure it out until I die method.These two people reacted too fast, how did they grow their brains? 】

[The most terrible thing is that this group game has only started less than a day ago, and it is like this now, what can be done later. 】

[There is no need to worry about others, at least in our opinion, no matter how incomprehensible the current situation is, it will not affect people's success in it, just follow the live broadcast with peace of mind. 】

[In the end, they still decided to leave this space?I originally thought that I was going to follow the life route here and decided to give up watching other players' split screen. Now I'll stay and observe for a while. 】

[Don’t forget that if you want to go to the control room, you have to find a way to deal with the nearly twenty professionally trained and physically strong crew members who are armed with weapons, and get control of the cruise ship for at least two hours. Whether you can get out is another matter. . 】

[So, is this going to start a group? 】
