In the dark steel room,
The surroundings were closed. A huge blue clock exuded a faint light.
It became the light source. After the truth clock finished speaking, Fu Wenduo asked the same question as the last round. Unlock the suppression of the truth world on players. After gaining freedom,
Tang Mo walked step by step to the truth clock.
He stood under the huge clock.
The next moment, Tang Mo reached out.
He passed through the blue clock.
His hand touched something. Tang Mo closed his eyes and sighed softly. His lips curved.
He opened the door with a click.
The clear sound of the door opening filled the room. At this moment, Zhao Xiaofei and Li Miaomiao were still standing in the same place with stunned expressions. Even though they could move their feet freely, they stared at Tang Mo's back. They still hadn't recovered from the huge change just now.
… What did he mean by the second round of hide-and-seek was over?
They hadn't started the hide-and-seek game.
They hadn't entered any corridors at all.
They hadn't left any footprints.
How could the second round be over?
But the truth clock didn't lie.
They definitely couldn't win this round.
Zhao Xiaofei and Li Miaomiao bit their lips.
They racked their brains to think about what was going on.
Tang Mo said, "Sure enough.
There is a staircase directly opposite. "
The group immediately recovered and hurried over. No one expected that there would be an extremely well-hidden door behind the truth clock. After opening this door,
Li Miaomiao looked at the scene outside the door.
"This is … another staircase?!" As soon as he said that, he was stunned.
Li Miaomiao seemed to remember something. She quickly ran to the door on the other side, the door they had just entered from, and opened it.
The two doors corresponded to each other.
If they went down the stairs, they could directly enter the room of the truth clock. They didn't have to look back and walked along the room. Through another door, they could enter the second staircase and go upstairs to the second floor.
The room of the truth clock became a middle passage, connecting the two stairs together.
Zhao Xiaofei felt that she seemed to have grasped the key. "If we want to clear the hide-and-seek game and find Schrodinger, we must find this door?" Judging from Tang Mo's reaction, this should be the case. But she still didn't understand. "Why have we already lost? We haven't even started our second round of hide-and-seek. "
"Because we are standing in this room, it means we can't find all the rooms."
Zhao Xiaofei was stunned.
The two doors opened at the same time, and two dark staircases appeared before the eyes of the players. Schrodinger stopped talking, but everyone knew that this short-tempered little black cat must be staring at every player in the room with its big green eyes, staring at the silent blue clock.
Everything was very simple.
"In the last round, I had Li Miaomiao ask the truth clock a question."
Li Miaomiao recalled, "What I'm asking is, how can we clear this hide-and-seek game?"
Tang Mo nodded. "Yes, this is your problem. But after the truth clock answered, the black tower shielded the answer for the fairness of the game. We didn't hear any answer and the black tower told us that the truth clock's answer was correct. It didn't lie and the question ended. "
Everyone still remembered this incident. At the time, they were so angry that they couldn't wait to use Schrodinger's cat food to hit the black tower's face.
Li Miaomiao asked, "So?"
The answer was shielded by the black tower. What was the point of this question?
Tang Mo smiled. "The black tower shielded the answer but it didn't shield the words that the truth clock said before the answer."
Everyone started to think about what the truth clock said at the time. At this time, a calm male voice was heard. "It said that there is only one way to clear the game."
Tang Mo looked up at Fu Wenduo. A moment later, he said, "Yes, it said that there is only one way to find Schrodinger."
Li Miaomiao was still a bit confused. "There is only one way. Then what?"
"Then the black tower already told us this method."
After a long time, Li Miaomiao and Zhao Xiaofei said in unison, "The seventh rule of the game is to search all the rooms and find Schrodinger?"
"Yes." Tang Mo said, "Schrodinger can lie and the truth clock can lie. However, the black tower never lies. It will only hide the conditions, bury traps, reduce the amount of information players have and even mislead them. However, it will never lie. Therefore, there is only one way to clear the game. Search all the rooms and find Schrodinger. Then the problem is simple. It is a one-stroke problem. However, this problem is a bit complicated because this castle can never be completed in one stroke. "
Four hours ago, Tang Mo listened to the black tower explain the rules of the game and determined that each corridor could only be walked once. He remembered a graphic problem he encountered when he took the civil servant exam after graduating from university.
The librarian in Suzhou was a career establishment and needed to take an exam. The graphic problem looked extremely complicated and each of the four options had intertwined lines. The requirement was to choose the following four pictures that couldn't be completed in one stroke. Tang Mo spent five minutes to choose the correct answer. At that time, he vaguely realized that there must be a theorem in the one-stroke problem.
Tang Mo suddenly thought that if Chen Shanshan had followed him to the tower attack game, the game would have been over.
At the start of the tower attack game, Tang Mo didn't know what this theorem was. They walked out of the kitchen to find Schrodinger and the map of the steel fortress. Tang Mo walked while drawing various patterns in his heart, looking for the theorem. The five players walked through the second floor. Tang Mo also discovered this theorem and demonstrated it himself. Then the problem suddenly came.
This fortress could never be completed in one stroke.
It was because it had two stairs.
"For any closed figure, if you want to finish drawing it in one stroke, there is a prerequisite. Among its intersections, there can only be 0 or 2 odd intersections. In addition, as long as the figure doesn't meet this condition, it can never be completed in one stroke. "
An odd intersection point referred to an intersection point that had an odd number of lines. Take Schrodinger's steel fortress as an example. Tang Mo found the second door hidden in the truth clock room. This was an odd intersection point. From this point, there were three ways to go. Go up the stairs, go left into the corridor and go right into the corridor.
After the earth went online, players' thinking speed improved. Zhao Xiaofei and Li Miaomiao couldn't prove this theorem at once but they thought of several figures in their minds and found that they all matched this theorem.
Zhao Xiaofei said, "If this is the case, there are two stairs in this castle. There is an odd point on both sides of each staircase. There are four odd points. It is impossible to walk through all the corridors without looking back! "
"Therefore, there are two odd points that can definitely become even points." Tang Mo paused and looked at Fu Wenduo.
10 minutes ago, Fu Wenduo whispered something in Tang Mo's ear as they walked to the bottom of the second staircase. He said that from their current position, the room of the truth clock was on their left, directly to the left.
The conditions to find this hidden door were extremely harsh.
First of all, the players had to know that there was only one way to find Schrodinger and that was to search all the rooms. Searching all the rooms meant that the players had to play a simple one stroke game.
Secondly, they had to figure out the basic map of the two floors in the first round of the game. They had to know the theorem of the one stroke problem and discover the truth in the second round. They had to find this hidden door and turn this steel fortress into a feasible one stroke drawing.
Finally, they needed players like Fu Wenduo who had a strong spatial thinking ability and memory.
Tang Mo had been thinking about how to turn four odd points into two. He wouldn't find that the two corridors were actually corresponding and the truth clock's room was in the middle.
All of the above conditions were indispensable. Even if the players faced the truth clock and didn't ask it questions, they wouldn't be able to find the truth if they simply won the question and answer and left the room.
Tang Mo said, "The odd points must be zero or two. This is only the first condition to complete the one stroke problem. The second condition is that our starting point must be an odd point. We can't walk casually in the second round because in the third round, we have to start from a fixed point. Otherwise, even if we discover the truth, we won't find Schrodinger as long as we don't start from an odd point. "
Tang Mo chose to enter the truth clock's room to determine the real odd point.
The truth clock's room was located at an odd point. This odd point wasn't a real odd point. Even if they hadn't started the second round, they couldn't win the game. This was the truth Tang Mo wanted to know from the mouth of the truth clock.
"This is Schrödinger's fortress, so of course it can move freely in every room. Thus, it doesn't need to search all the rooms and can hide in any room the players haven't entered. Only by searching all the rooms will it not dare to cheat … This game is really interesting, Great Schrodinger. "
"You shameless humans!!!" The black cat roared. Still, no one gave it face.
They already knew the method to clear the instance and found the hidden door. The five players left the room through this door, ready for the next round of the game.
Before leaving the room, Tang Mo turned to look at the truth clock.
On the huge blue clock, the seconds ticked away. This clock was like an ordinary clock. As it said at the beginning, it accurately told the time for Schrodinger. Schrodinger only needed it to accurately tell the time. Perhaps it wasn't needed now.
It couldn't be a coincidence that the truth clock was arranged in this special room.
Tang Mo walked out of the room and shook his head with a smile.
The black tower turned a blind eye and allowed Schrodinger to cheat, allowing it to move freely in the 108 rooms. The black tower would also give the players a hint. The truth clock was a hint. If it wasn't the truth clock, the difficulty of the game would be greatly increased. Tang Mo wouldn't know the real method to clear the instance and Fu Wenduo wouldn't confirm that the stairs on the left and right sides corresponded to each other.
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 asked, "Black tower, can we give up the second round and start the third round of hide-and-seek?"
The black cat roared, "You bastard!!!"
The black tower spoke in an emotionless voice. "Yes. Please confirm to give up the second round. "
Tang Mo stated, "We give up."
