The Earth is Online - Chapter 161

[Chapter 161]

In a dark steel room, surrounded by airtightness. A huge blue clock exudes a faint glow and becomes a light source. After the truth clock finished saying this, Fu Wenduo asked the same question as the previous round, unlocking the world of truth’s suppression of the player. After gaining his freedom, Tang Mo walked to the truth clock step by step, and he stood under the huge clock.

The next moment, Tang Mo stretched out his hand and passed through the blue light clock.

His hand touched something steadily, Tang Mo closed his eyes and sighed softly. He raised his lips and opened the door with a click.

The crisp sound of the door opening sounded in the room, and at this moment, Zhao Xiaofei and Li Miaomiao were still standing in the same place with dumbfounded expressions. Even if they could move their feet freely, they stared blankly at Tang Mo’s back. They haven’t recovered from the great change just now.

…what is the second round of hide and seek game over? !

They haven’t started a game of hide-and-seek, they haven’t entered any corridors at all, and they haven’t left any footprints. How could the second round of the game be over?

But the truth clock didn’t lie, and they certainly couldn’t win again this round.

Zhao Xiaofei and Li Miaomiao bit their lips, racking their brains to think about what happened.

Tang Mo said: “Sure enough, this staircase is directly opposite.”

Everyone immediately came to their senses and hurried over. No one would have thought that behind the truth clock there was a small door that was extremely tightly hidden. After opening the door, Li Miaomiao looked at the scene outside the door and said in amazement, “This is… another staircase?!” When the voice fell, Li Miaomiao seemed to remember something, and she quickly ran to the room on the other side. The door, the one they had just entered, opened the door.

The two doors are opposite each other.

Going down a staircase leads directly to the room of the clock of truth. Don’t look back, walk along this room, through another door, you can go to the second staircase, go upstairs to the second floor.

The room of the clock of truth becomes a middle passage, connecting the two stairs together.

Zhao Xiaofei felt that she had grasped the key: “If you want to clear the game of hide and seek and find Schrödinger, you must find this door?” Judging from Tang Mo’s reaction, it should be like this. But she still didn’t understand, “Why are we losing now? We haven’t even started our second game of hide-and-seek.”

Tang Mo: “Because when we stand in this room, it means that it is impossible for us to find all the rooms.”

Zhao Xiaofei was stunned for a moment.

The two doors were opened together, and two dark staircases came into the eyes of the player. Schrödinger stopped talking, but everyone knew that this irritable little black cat must be staring straight at every player in the room with those big green eyes, staring at the silent cat. blue clock.

Everything is actually very simple.

“In the last round of the game, I asked Li Miaomiao to ask the truth clock a question.”

Li Miaomiao recalled: “What I asked was, how can we clear this hide-and-seek game.”

Tang Mo nodded: “Yes, this is your question. But after the truth clock answered, the black tower blocked the answer for the fairness of the game. We did not hear any answer, and the black tower told us that the truth clock’s The answer was correct, it didn’t lie, and the question was over.”

Everyone still remembers this incident. At that time, they were so angry that they could not wait to use Schrodinger’s cat food to cover the black tower’s face.

Li Miaomiao: “So what?”

The answer is blocked by the black tower, what is the point of this question?

Tang Mo smiled and said, “The black tower blocked the answer, but it didn’t block the answer, what the truth clock said before.”

Everyone began to think about what the truth clock said at the time. At this time, a calm male voice sounded: “It said that there is only one way to clear this game.”

Tang Mo raised his head and looked at Fu Wenduo. After a while, he said, “Yes, it said that there is only one way to find Schrödinger.”

Li Miaomiao was still a little confused: “there is only one way, then what?”

“Then, the black tower has already told us this method.”

After a long while, Li Miaomiao and Zhao Xiaofei said in unison: “The seventh rule of the game, search all the rooms, you will definitely find Schrödinger?!”

“Yes.” Tang Mo said, “Schrödinger can lie, and the truth clock can lie. But the Black Tower will never lie. It only hides conditions, lays traps, reduces the amount of information for players, and even misleads players. But it will never lie. Lie. So there is one and only one way to clear the game – search all the rooms, you will definitely find Schrödinger. Then this problem is simple, this is a one-stroke problem. But this problem is a bit more complicated, because this castle is forever It is impossible to finish a painting in one stroke.”

Four hours ago, when Tang Mo listened to the black tower explaining the rules of the game and determined that each corridor can only be walked once, he remembered a graph problem he encountered when he was taking the civil service exam when he graduated from college.

Librarians in Suzhou are career establishments and require examinations. The figure question looked extremely complicated, with lines interlaced for each of the four options. Its requirement is to select the following four figures that cannot be drawn in one stroke. It took Tang Mo five minutes to choose the correct answer, and then he vaguely realized that there must be some kind of theorem in the one-stroke painting problem.

Tang Mo suddenly thought that if Chen Shanshan were to follow him to participate in the tower attack game this time, the game would probably be over long ago.

When he started the tower attack game, Tang Mo didn’t know what this theorem was. When they walked out of the kitchen, looking for Schrödinger and understanding the map of the steel fortress, Tang Mo drew various patterns in his mind while walking, looking for the theorem. After the five players walked to the second floor, Tang Mo also discovered this theorem and demonstrated it by himself. But suddenly the problem came.

This fortress can never be completed in one stroke.

Because it has two stairs.

“Any closed figure, if you want to complete it in one stroke, requires a precondition: in its intersections, there can only be 0 or 2 odd intersections. In addition, as long as the figure does not meet this condition, You can never finish a painting in one stroke.”

An odd-numbered intersection refers to an intersection that has an odd number of lines. Taking Schrödinger’s steel fortress as an example, this is an odd intersection before Tang Mo finds the second door hidden in the truth clock room. From this point there are three ways to go: go up the stairs, enter the corridor to the left, and enter the corridor to the right.

After the earth went online, the players’ thinking speed improved. Although Zhao Xiaofei and Li Miaomiao couldn’t prove this theorem at once, they thought about a few graphics in their minds and found that they all conformed to this theorem.

Zhao Xiaofei said: “If this is really the case, there are two staircases in this castle. There is an odd number on both sides of each staircase, there are four odd points in total. It’s impossible to walk through all the corridors without turning back! ”

“So, if there are two odd-numbered points, it can definitely become an even-numbered point.” After a pause, Tang Mo glanced at Fu Wenduo.

Ten minutes ago, when they reached the bottom of the second staircase, Fu Wenduo said something in Tang Mo’s ear. He said that at this position, the room of the Clock of Truth was on their left, right on the left.

To be able to find this hidden door, the conditions are actually extremely harsh.

First of all, players must clearly know that there is only one way to find Schrödinger, and that is to search all rooms. Finding all the rooms means that the player has to play a simple one-stroke game.

Secondly, they have to figure out the basic map of the two-story building in the first round of the game, know the theorem of the one-stroke drawing problem, and discover the truth in the second round of the game, find the hidden door, and turn this steel fortress into a Feasible one-stroke graphics.

Finally, players like Fu Wenduo with strong spatial thinking ability and memory are also needed.

Tang Mo has been thinking about how to turn four odd-numbered points into two. He wouldn’t find out that the two corridors actually corresponded, with the truth clock’s room sandwiched in between.

All the above conditions are indispensable. Even if the player is confronted with the clock of truth, he does not ask it a question, but simply wins the quiz and leaves the room, and he cannot find the truth.

Tang Mo: “The odd-numbered points are 0 or 2. This is just the first condition for completing the one-stroke painting problem. The second condition is that our starting point must be an odd-numbered point. We can’t just walk around in the second round of the game, because In the third round of the game, we must start the game from a certain fixed point. Otherwise, even if we discover the truth at that time, as long as we do not start from an odd point, we will not find Schrödinger.”

Tang Mo chose to enter the room of the truth clock at the beginning, in order to determine the real odd point.

The room of the truth clock is located at an odd point. This odd number isn’t really an odd number, so it’s impossible for them to win the game even if they haven’t even started the second round. This is the truth that Tang Mo wants to know from the truth clock.

Grea said with a smile: “This is Schrödinger’s fortress, of course it can move freely in every room. So without searching all rooms, it can hide in any room that the player has not entered. It doesn’t dare to cheat until it has searched all the rooms… This game is really interesting, Your Excellency the great Schrodinger.”

“You shameless humans!!!” The little black cat growled. But no one will give it face.

Knowing the clearance method, they also found this hidden door. Five players left the room through this door in turn, preparing for the next round of the game.

Before leaving the room, Tang Mo turned to look at the truth clock.

On the huge blue-light clock, the seconds ticked by. This clock is like an ordinary clock, as it is said at the beginning, it tells the time exactly for the great Schrodinger. Schrödinger only needed it to tell the time accurately, and perhaps not now.

It cannot be a coincidence that the truth clock is placed in this particular room.

Tang Mo walked out of the room, smiled and shook his head.

The Black Tower turned a blind eye, allowing Schrödinger to cheat and allow it to move at will in the 108 rooms. The black tower will also prompt the player. The truth clock is a reminder. If the truth clock is not placed here, the difficulty of this game will be greatly increased. Tang Mo wouldn’t know the real customs clearance method, and Fu Wenduo wouldn’t be sure that the stairs on the left and right correspond to each other because he was impressed.

The five players walked to the top of the corridor. Li Miaomiao wanted to walk more, but Tang Mo stopped her.

Tang Mo raised his head and said, “Heita, can we just give up the second round of the game and start the third round of hide-and-seek?”

The little black cat roared: “You bastard!!!”

Heita said in an emotionless voice: “Yes. Please confirm to give up the second round of the game.”

Tang Mo: “We give up.”

“Ding Dong! The second round of hide-and-seek is over, and the player fails. After a ten-minute break, the third round of hide-and-seek is forced to start.”
