Tokyo Ghost Story Capture Master

In any game that is linked to numbers, there is a secret to winning.

This is also related to the sequence of moves in the game.

The rules have been figured out. As long as the final key can be turned, Dazai Shuu will win.

There is no limit to the number of times you can turn the key, but only the third level can be turned all at once. The keys on the other two levels cannot be turned all the first time.

It is also not possible to turn the key on the second floor and the key on the first floor in one turn. You can only turn the key on the same floor.

After Osamu Dazai turned the key, Mary-san turned the remaining keys somewhere.

"Oh, I understand." Sasakura Mana thought thoughtfully after listening to the rules, "Then what will happen if Miss Mary turns the last key?"

"We may not be able to catch her tonight." Dazai Xiu shook his head.

He really wants to catch Miss Mary. This opportunity will never come again!

Since Miss Mary turned the two keys on the second floor, it was now Dazaishu's turn.

In this game, what he wants to know is whether he can win next.

The way to judge is simple.

As long as the number of keys on each floor is converted into binary, you can calculate whether Dazai Shu has a chance of winning next.

There are three keys on the third floor and five keys on the second floor. Suppose there are also five keys on the first floor.

3, 5, 5.

Converted into binary, they are:

11, 101, 101.

Add these three numbers together, and if one of the resulting numbers is an odd number, whoever attacks first will have a sure way to win.

Dazai Shu told Sasakura Mana the rules.

"Huh? How did you calculate this? How can you be sure that this is the case?" She didn't understand.

Osamu Dazai explained: "The person who attacks first turns the key using the binary calculation method so that the single digit of the added number becomes an even number, and then passes it to the opponent. In the end, he will definitely get the last key.

"If you don't believe it, let's try it!"

In order to study the rules, the two sat on the floor.

Dazai Shu took back the Cerberus and turned it into thirteen teeth, and then placed it on the ground according to the distribution of keys on each floor.

Just like the previous action, first, he took away the three teeth on the third layer.

Then, Sasakura Mana took away the two teeth on the second level.

This is the first round of action.

What remains are the three teeth on the second layer and the five teeth on the first layer.

Now it's Dazai Shu's turn.

The binary number of 3 is 11, 5 is 101, and the added number is 112. There is an odd number in the number, so it is sure to win.

He took away two teeth from the first floor.

This leaves only three teeth on the first floor and three teeth on the second floor.

The binary number of 3 is 11, which adds up to 22, and the ones digit is an even number. It's Mana Saakura's turn.

She was already going to lose no matter what.

Looking at the teeth on the floor, Saakura Mana simulated all the possibilities, and she suddenly realized.

The score is exactly the same as that of Osamu Dazai!

Sasakura Mana raised her head and looked at Dazai Shu with wonder and admiration, admiring her very much.

Not to mention that he can think of a way to crack it, he can maintain such a level of calmness in the weird rules and at the same time, he also has the ability to think flexibly.

As expected, professionals are professionals, and there is a fundamental difference between them and the cliche spiritualists on the Internet and in society.

"Do you understand?" Dazai Xiu stood up and retracted all the hell dog teeth.

Sasakura Mana nodded slightly and stood up, "Then how many keys should we turn now?"

"What we should do now is not to turn the key, but to see how many keys there are on the first floor."

"Yes!" Sasakura Mana nodded quickly.

She became slightly excited.

The originally frightened mind regained its activity slightly after thinking about it just now.

While going downstairs, Dazai Shu said:

"When we came, we had already turned three keys on the third floor, and two of the five keys on the second floor were turned by Miss Mary.

"So we know there are three keys left."

The binary version of 3 is 11.

The key lies in the number of keys on the first floor.

After all, they were just simulating. They just assumed that there were five keys on the first floor. The actual situation may be different and must be investigated on the spot.

"If we were to turn the final key, the number of keys on the first floor should be something other than three."

If the number of keys on the first floor is 3, the binary sum of the number of keys on the second floor is 22.

It’s just impossible to win.

"The game itself requires us to get to the second floor to realize its essence. On the third floor we only see the keys. Who knew it was a Nim game?

"Therefore, it is inevitable that I turn three keys on the third floor, so the keys on the first floor should be designed not to have three keys, giving us a chance to break through."

As they spoke, they walked to the first floor.

Sure enough, I saw the same circuit board.

"You, you are really amazing." Sasakura Mana couldn't help but sigh again.

"Hmph, it's not bad. After all, it's my job to eliminate ghost stories, and it involves a lot of rules. Of course, I will have a certain level of reasoning ability."

Dazai Xiu raised the corners of his mouth confidently and opened the iron cover in front of the circuit board.

I saw three keys inside.

The two of them were speechless: "..."

……

In the dim room, stood a slim figure. She was wearing a gothic lolita-style dress with black and red lace all over the skirt. From her exposed jade-white calves, she wore a pair of red high heels.

Her face was expressionless, her brown eyes stared straight ahead without moving, and her skin was so white that she didn't look like a human being, just like the cold snow.

Her long hair reaches her waist, but it looks very stiff and lacks flexibility and flexibility.

"Hello, I'm Dazai Shu.

"I'm at your door."

A man's voice came from behind the door.

Click, the door handle turns.

The door to the room she was in opened automatically.

It was only then that she finally trembled slightly. She slowly turned her swan-like snowy neck at an unnatural degree, and her eyes turned away.

Even without any change in expression, her doll-like face would still make people think she was surprised.

She looked towards the door.

"Hello, I am Dazai Xiu, and I am here in front of you."

I saw Dazai Xiu really standing at the door, leaning against the door frame with his arms folded, looking coldly at Miss Mary inside.

Similarly, Sasakura Mana was also nearby, huddled behind Dazai Shu and peeking in, "This is Miss Mary's true form..."

Sasakura Mana's cell phone rang again. She quickly took it out and dialed, and heard a voice from the other end:

"Hello, I am……"

"Okay, no need to say anything." Dazai Xiu raised his hand to interrupt what Miss Mary wanted to say.

"Do you want to know how we found your location and opened the door to your location?

"Oh, it's actually very simple. After all, it's a weird story about rules. You can just break it according to the rules."

It was a little late, so Dazai Shu yawned a little tiredly. It was already time to go to bed at this point.

Working overtime is still a bit hard.

He seemed relaxed and indifferent.

At the end of the rules, Osamu Dazai should have turned the two keys on the first floor.

Then Miss Mary turned the two keys to the second floor.

This leaves only one key for the first level and one key for the second level.

Only the keys on the same floor can be turned in one round. In any case, the person who can turn the last key should be Miss Mary.

But why was Dazai Shu the one who opened the door?

Miss Mary released her senses and went to the corridors of the three floors through her clones.

She saw it.

In the corridor on the second floor, inside the circuit board.

Three of the keys were covered with wire.

The three keys were tied together with wires. When Miss Mary turned the two keys, the remaining key was also moved.

So, without her knowledge, she turned the three keys on the second floor with her own hands.

Dazai Shunori turned the last key on the first floor and opened the door to Miss Mary's location.

This guy……

Miss Mary stared at him.
