Chiba knew exactly what it was - Japan's most famous gesture signal, the naval gesture flag.

The flag of the naval gesture flag has eight directions: six, seven, half-past, nine, ten-and-a-half, twelve, half-past, three-point, and four-and-a-half. If these eight positions are marked as positions 1 to 8, then the vast majority of flags (29 out of 30 gestures) can be represented by two numbers, while the same majority (28 out of 29 bells) have two different digits, where the right hand is placed in the direction of the smaller number and the left hand is placed in the direction of the larger number.

12，13，14，15，16，17，18，23，24，25，26，27，28，34。。。 The 28 two-digit numbers arranged in this way represent A(1), B(2), C(3), D(4), E(5), F(6), G(7), H(8), I(9), K(0), L, M, N, O, P, Q, R, S, T, U, Y, cancel, numeric symbols, J/alphabets, V, W, X, Z (yes, not in 26-letter order)

The twenty-ninth flag is 11, which means standby, space.

The thirtieth flag is a 90-degree up-and-down movement of the left and right hands (between 2 and 4 for the right hand and between 6 and 8 for the left hand, with the hands remaining symmetrical. ), meaning false.

Conan's flag gesture is the letter K, and the meaning of this flag is - expect conversation. In other words, Conan intends to talk to himself.

As soon as Qian Yu thought of this, he saw that Conan had already walked in front of him.

"Thousand feathers?" Conan asked tentatively, lowering his voice. "Where are you?"

"This kid didn't expect me to understand the flag... Qian Yu shook his head with a smile, walked out, and said in the same soft voice, "Conan, I'm here." ”

"Thousand feathers," Conan let out a sigh of relief when he saw a thousand feathers. "What about them?"

"I arranged for them to hide in the locker room," Chiba asked, gesturing to a few of the locker rooms inside. "What the hell is going on?"

"I just went to the guardhouse," Conan's face immediately turned bad. "The four robbers, one of them is the Kamen Superman who gave us an autograph during the day, and the other three are also wearing the villain costumes of Kamen Superman. The kidnappers tied to the ground were three police officers and an elevator attendant. ”

"Why is the elevator attendant here?" Chiba was surprised. "It's closed!"

"I guess I was kidnapped before I could leave," Conan glanced in the direction of the stairs. "Don't talk about that, follow me to the third floor, where is the survival supply area, there is mineral water and compressed biscuits, and there are tents, so you can survive tonight."

"Won't it be discovered?" Qian Yu worried. If the gangsters also get to that level for some purpose, it is dangerous to use these things with such a swagger.

"The third floor is a sports equipment store, a survival supply store, and a school supply store, all three of which are big and difficult to take, and in the case of only four robbers, they must be the first to get gold and silver jewelry, and then expensive electronic supplies, so it is unlikely that they will come here. As for if they want to find a place to rest, they should go to the furniture area on the 5th floor and find those comfortable beds to sleep in. If they want to find something to eat, they will only go to the supermarket on the second floor, and it is impossible to come here. After Conan finished speaking, he walked in the direction of the locker room, called out Mitsuhiko Ayumi Motota, and the five of them went up to the third floor together.

"It's a compressed biscuit," Chiba put an iron box in front of Mitsuhiko Mototabu. "It's a little dark, and you won't be able to see clearly later, so remember, as long as it's in a metal box like this, it's all compressed biscuits."

"Compressed biscuits? What's that? Yuan Tai asked. Is it a cookie? ”

"It's pretty much the same, but try not to eat too much, because compressed cookies are high in energy... Qian Yu hurriedly explained.

"I think Genta is probably the least suitable person on the planet to eat compressed cookies... The corners of Conan's mouth twitched, and he said. (The characteristic of compressed biscuits is that they can't quench hunger by themselves, but the energy is extremely high, and it is an absolute fattening artifact for a guy like Yuantai who eats until he is full)

"That's right, but we don't have any other choice." Qian Yu sighed. "You three come here, I'll teach you how to eat compressed biscuits."

。。。

"I've put plenty of compressed biscuits and drinking water here, you must hide in this tent and don't come out," Qian Yu said to the three people in the tent after zipping up the two tents next to him. "Conan and I need to go out for help, I don't know when we will be back, you must pay attention to your own safety!"

"Why can—" Before Yuan Tai could finish speaking, Qian Yu choked on a word.

"You're so reckless, the occasion doesn't give you a chance to correct your own mistakes, understand?"

"You are too impatient with him, people will always pass, and then they can change." On the way to the stairs with Chiha, Conan suggested.

"It takes time, and time is what is lacking at the moment." Qianyu stretched the Traceless Umbrella and kept it in a retracted state, and said. "What do we do next?"

"I'm going to fight guerrilla warfare, what do you think?" Conan said what he was going to do.

"Ask for help first, right?" Qian Yu pointed to the top of the building. "Although the phone is cut off, and these glasses are obviously soundproof + bulletproof double glazing from the labels on the edges, the top floor is definitely open, and the success rate of calling for help there is very high, and as long as the door is closed, it is difficult to be found."

"That's fine, then let's go to the top floor first." Conan thought about it and felt that this method was indeed more secure, at least to maximize the chance that the police would arrive to help.

"There's someone on the sixth floor, probably under the gem propaganda slogan," Qian Yu walked to the fifth and a half floors, suddenly stopped advancing, and whispered as he leaned down on the stairs. "Kamen Superman plus a sidekick."

"They're not going to pay attention here, let's go up one level and see if there's any." Conan gestured with his hand, and then tiptoed through the visual blind spot of the two robbers who were looting gold, silver and jewelry.

"Is there anyone on the seventh floor?" The cat walked through the six flights of stairs, and Chiba asked Conan on the sixth and a half floors.

"I guess the remaining two people are in the central control room on the second basement floor, because there's no one here." Conan made an "OK" gesture. "Let's go up to the top floor!"

The top floor is a basketball court, and the entire top floor is surrounded by barbed wire with a height of more than 5 meters. A flatbed cart full of basketballs is parked in the middle of the basketball court.

"This barbed wire fence has to be six or seven meters long, right?" Qian Yu "cut" and said. "How are we going to call for help?"

"When the car passes by, throw the basketball down to get their attention, and then you can call for help."

"What should I do if I smash my car?"

"Anyway, we have recovered so much of the loss of jewelry, they probably won't mind helping us compensate, right?"

"Are you sure?"

"How can I have time to care so much!"
