Bai Youwei spread out the pictures she drew for everyone to see.

"We have been walking for so long and have now figured out that there are twelve horizontal rooms in total. If we mark them according to the number sequence of 1-12, the Taurus will stay at No. 2, and we are now on No. 12.

Suppose the Taurus does not move any time he eats, and it has to walk at least 8 squares to catch up with us."

Bai Youwei pointed at the teleportation point with her finger.

"According to common sense, this is a distance that cannot be caught up in any case, but there are unknown number of teleportation points in the maze. If I were a Taurus, I would choose a location not far from each teleportation point, predict the player's whereabouts, and then select the corresponding teleportation point.

Therefore, if you want to avoid being caught up by the Tauren, you must meet at least two conditions.

First, avoid all teleportation points;

Second, avoid all blind spots.”

Chen Hui said hesitantly: "But now... we are both near the teleportation point and very close to the dead corner..."

Bai Youwei thought for a while and said, "Let's go west and then north. If this maze is a 12x12 square, then we only need to go nine times and we will reach the end."

"Are you sure it's 12x12?" Du Lai asked.

"I just said that there is a possibility." Bai Youwei said, "Whether it is a maze or a game, you usually prefer regular shapes. The most common one is a square. Now we know that there are 12 locks and 12 keys, and the horizontal room also happens to have 12 clothes and trouser racks. If there are also 12 vertical ones, then the maze is likely to be a square."

Leonid asked: "So what if you know it's a square?"

"Not what." Bai Youwei lowered her eyes and whispered, "At least we will not be forced into a dead corner when the Tauren chases us."

"But..." Chen Hui hesitated, "If we want to confirm this... we will at least go to the dead corner again."

They have already walked through two "corners". To prove that the maze is square, at least one "corner" needs to be determined.

When you walk into a "blind corner", you are very likely to be surrounded by the Minotaur.

Bai Youwei thought for a while and said calmly: "There is nothing we can do about it. Even if we know that the dead corner cannot be left, in order to clarify the location of each key, we still need to search every room in the maze."

"Then let's go." Shen Mo said lightly, "Go out as soon as possible."

Bai Youwei glanced at him and said, "Let's go west."

The group advanced westward and when they were putting chickens, Du saw a key in the stone chamber on the west side, so they advanced another square and got the sixth key.

"I'm a little convinced now that this maze may be 12x12," Du said.

Asarina asked him, “Why?”

"Because the probability of encountering a key is very high." Du Lai raised his lips, "If the number of rooms here is as high as 1,000, or 10,000, it is almost impossible to pick up the key by luck, right? But if it is 12x12, then the total number of rooms is 144. Excluding the room at the teleportation point, the probability of picking up the key... may be around 10%.

"Is 10% very high?" Chen Hui couldn't help asking.

Du Lai smiled and asked her: "Do you know the Double Color Ball?"

Chen Hui nodded, "I know, what's wrong?"

"The lowest prize for the Double Color Ball is the fifth prize, with a prize of 5 yuan, and the probability of winning is about 6%. "Du said, "The probability of us picking up the key is much higher than the probability of winning the Double Color Ball."
