Chapter 161: The way to pass the game~

The dark steel room is sealed off. A giant blue clock emits an eerie glow and becomes the source of light. After the Truth Clock has spoken, Fu Wenduo opens his mouth and asks the same questions as in the previous round, unlocking the suppression of the player in the world of Truth. Having been freed, Tang Mo takes one step in front of the Clock of Truth, and stands beneath the huge clock.

The next moment, Tang Mo reached out and passed through the clock of blue light.

His hand steadily touched something, Tang Mo closed his eyes and sighed softly. He curled his lips and snapped this door open.

The sound of the door opening was heard in the room, and at that moment, Zhao Xiaofei and Li Miaomiao were still standing in the same place with confused faces. Even though they could move their feet freely, they were still staring at Tang Mo's back. They had not yet recovered from the dramatic change they had just experienced.

...... What do you mean the second round of hide-and-seek is over?!

They hadn't even started the game of hide-and-seek, they hadn't even entered a single corridor, they hadn't left a single footprint, so how could the second round of the game be over?

But the truth clock did not lie, and there was certainly no way they could win this round of the game again.

Zhao Xiaofei and Li Miaomiao bit their lips, racking their brains as they tried to figure out what was going on.

Tang Mo said, "Sure enough, directly opposite is this staircase."

Immediately, everyone came back to their senses and rushed over. No one expected that there would be a small door behind the clock of truth that was extremely well hidden. After opening this door, Li Miaomiao looked at the scene outside the door and said in dismay, "Is this ...... another staircase? As if remembering something, Li Miaomiao quickly ran to the door on the other side of the room, the door they had just entered, and opened it.

The two doors correspond remotely.

Take one of the stairs down and you can go straight into the room with the truth clock. Do not turn back and follow this room forward, through another door, into a second staircase and up the stairs to the first floor.

The room with the truth clock becomes a middle passage, linking the two staircases together.

Zhao Xiaofei felt as if he had grasped the key: "You have to find this door to get through the game of hide-and-seek and find Schrödinger?" Judging by Tang Mo's reaction, that would be the case. But she still doesn't understand, "Why are we already losing now? We haven't even started our second round of hide-and-seek yet."

Tang Mo: "Because when we stand in this room, it means that it is no longer possible to find all the rooms."

Zhao Xiaofei froze abruptly.

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

Everything is actually very simple.

"During the last round of games, I asked Li Miaomiao to ask the truth clock a question."

Li Miaomiao recalls, "I was asking how we could get through this game of hide-and-seek."

Tang Mo nodded: "Yes, that was your question. But then after the truth clock gave its answer, The black tower blocked the answer for the sake of fairness of the game. We didn't hear any answers, The black tower told us that the truth clock's answer was correct, that it wasn't lying, and that was the end of the question."

Everyone still remembers this and they were all so angry that they wanted to smother The black tower with Schrödinger's cat food.

Li Miaomiao: "So what?"

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

Tang Mo laughs: " The black tower blocks the answer, but it doesn't block the answer before the truth clock says a word."

The crowd began to ponder what exactly the Truth Clock had said then, when a deep, male voice rang out, "It said that there was only one way to pass this game."

Tang Mo looked up at Fu Wenduo and after a moment he said, "Yes, it says there is only one way to find Schrödinger."

Li Miaomiao is still a bit confused: "There's only one way, then what?"

"And then, this method The black tower has already told us."

After a long time, Li Miaomiao and Zhao Xiaofei said in unison: "Rule number seven, look in all the rooms and you'll find Schrödinger?"

"Right." Tang Mo said, "Schrödinger can lie, the truth clock can lie. The black tower, however, never lies. It only conceals conditions, lays traps, reduces the amount of information available to the player, and even misleads the player. But it will never lie. So there is one and only one way to get through this game - look in all the rooms and you will definitely find Schrödinger. Then the problem is simple - it's a one-stroke problem. But then again the problem is a bit complicated, because the castle can never be walked through in a single stroke."

Four hours earlier, after Tang Mo had listened to The black tower explain the rules of the game, making sure that each corridor could only be walked once, he was reminded of a graphical problem he had encountered during his civil service exams when he graduated from university.

The librarian at Suzhou is a career position and requires an examination. The graphical question looked extremely complex, with each of the four options having interlocking lines. It required the selection of four figures that could not be drawn in one stroke. It took Tang Mo five minutes to choose the correct answer, and it was then that he sensed that there must be some kind of theorem in the one-stroke problem.

It occurred to Tang Mo that if Chen Shanshan had been allowed to come along and participate in the tower attack, the game would have been over long ago.

Tang Mo didn't know what this theorem was when they started the tower attack game. As they walked out of the kitchen in search of Schrödinger and a map of the Iron Fortress, Tang Mo drew various mental pictures of the theorem as they walked. After the five players had finished the first floor, Tang Mo had also found the theorem and had argued it himself. But then the problem came.

This fortress can never be walked through in a single stroke.

Because it has two staircases.

"Any closed figure that wants to be walked through in one stroke requires one prerequisite: it can only have 0 or 2 odd intersections in its intersection. Other than that, any figure that does not meet this condition can never be completed in a single stroke."

An odd number of intersections refers to an intersection where it has an odd number of lines. Take Schrödinger's Iron Fortress, for example, before Tang Mo finds the second door hidden in the Truth Clock room, which is an odd-numbered intersection. From this point there are a total of three ways to go: up the stairs, left into the corridor, and right into the corridor.

Zhao Xiaofei and Li Miaomiao were unable to prove the theorem at once, but they worked out a few shapes in their heads and found that they all fitted the theorem.

Zhao Xiaofei said: "If this is true, there are two staircases in this castle. Each staircase has an odd number of points on either side, and in total ...... has four odd points. It's simply impossible to walk through all the corridors without turning back!"

"So there are two odd dots that can definitely become even dots." After a pause, Tang Mo looked at Fu Wenduo for a moment.

Ten minutes earlier when they had reached the bottom of the second staircase, Fu Wenduo had whispered in Tang Mo's ear. He said that in this position now, the room with the truth clock was to their left, directly to the left.

The conditions for being able to find this hidden door are in fact extremely demanding.

First of all, the player has to be clear that there is one and only one way to find Schrödinger, and that is to look in all the 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 floors in the first round of the game, they have to know the theorem of the one-stroke problem and they have to discover the truth in the second round of the game, find this hidden door and turn this steel fortress into a viable one-stroke figure.

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

Tang Mo has been thinking about how to turn four odd dots into two. He would not find that the two corridors actually corresponded directly, with the room of the truth clock sandwiched between them.

All of the above are required. Even if the player leaves the room without asking the truth clock questions when confronted with it, and simply wins the quiz, he will not find the truth.

Tang Mo: "Having zero or two odd points is only the first condition for completing the one-stroke problem. The second condition is that our starting point must be some odd number of points. We can't just go anywhere in the second round, because for the third round, we have to start from some fixed point. Otherwise even if we find the truth by then, we will not find Schrödinger as long as we do not start walking from an odd numbered point."

Tang Mo chose to enter the room of the truth clock at the beginning in order to determine the true singularity.

The Truth Clock room is located at an odd numbered point. This odd numbered point is not a true odd numbered point, so even before their second round has started to go, it is already impossible for them to win the game. This is the truth that Tang Mo wants to know from the truth clock.

Grea's voice rings out with laughter: "This is Schrödinger's fortress, and it can of course move freely in every room. So without searching all the rooms, it can hide in any room that the player hasn't been in. Only by searching all the rooms will it not dare to cheat ...... This is an interesting game, great Lord Schrödinger."

"You shameless humans!!!" The little black cat snarled. But no one would give it face.

Already knowing the way through, they also found this small hidden door through which the five players left the room in turn, ready for the next round of the game.

Before leaving the room, Tang Mo turns his head to look at the truth clock.

The seconds clacked away on the huge blue clock. This clock seems like an ordinary clock, as it says at the beginning, it tells the time accurately for the great Lord Schrödinger. Schrödinger only needed it to tell the time accurately, and perhaps it doesn't need it now.

It can't be a coincidence that the Truth Clock was placed in this particular room.

Tang Mo walks out of the room, smiling and shaking his head.

The black tower turns a blind eye and lets the Schrödinger cheat, allowing it to move around the 108 rooms as it pleases. The black tower will then also give the player a hint. The truth clock is a hint. If it hadn't been placed here, the game would have been much more difficult. Tang Mo would not have known the real way through, and Fu Wenduo would not have been impressed enough to make sure that the left and right staircases corresponded to each other.

The five players reached the top of the corridor and Li Miaomiao wanted to go further when Tang Mo stopped her.

Tang Mo looked up and said, " The black tower, can we just abandon the second round and start the third round of hide-and-seek?"

The little black cat roared, "You bastard!!!"

In an emotionless voice, The black tower said, "Yes. Please ask the player to confirm the abandonment of the second round."

Tang Mo: "We give up."

"Ding Dong! The second round of hide-and-seek is over and the player has failed. After a ten minute break, a third round of hide-and-seek will be forced."
