In front of the laptop in the administrator's room, Yumi grabbed her hair and went crazy in front of the computer interface.

Above is an interface for entering an 8-digit password......

"Please enter the 8-digit password, only Yodo-kun, you can't enter the wrong ......" Sato looked at the prompt on the interface, frowned and looked at the silent administrator, "What do you mean?" Is there a place for the envelope in the computer? ”

"That's what happened," said the old man, averting his eyes to the joke, "the hint of the password is in this room, and I won't say anything else." ”

"Damn!"

Yumi glared at the old man in annoyance and picked up a piece of paper full of strange patterns.

"Only the square paper in the garbage basket is suspicious, but what is it painted on it? I can't read it at all! ”

"That's the password for passwords, isn't it?" Sato asked and looked at Gao Cheng, "Joto." ”

Fortunately, the detective was brought over, so it shouldn't be a big problem......

"I can't solve the code." Gao Cheng ignored the stunned Sato and the two, looked at the code paper and shook his head.

It's all messy symbols, and there are no rules, even if Conan comes, I'm afraid it will be difficult to unravel, this dead old man is testing Yumi, it's a dilemma at all.

"Huh?" Yumi's face was ugly, "Can't you even understand Joto?" ”

"It's true that I can't read it, but," Gao Cheng's gaze swept across the room, "I probably know how to interpret it, generally speaking, this kind of garbled code will have a decryption paper to cover the useless code, but there is only this one piece of paper in the room, so I can only think of a way from this paper itself......"

"Decryption paper?" Yumi was stunned, "Will you use shogi to cover it?" The shogi board in the middle of the room is so eye-catching, it's like saying, 'Hurry up and see me,' and it feels like a hint......"

"Although I don't know much about shogi, the code should have nothing to do with shogi," Gao Cheng glanced at the old man who was yawning deliberately, and continued, "The reason why I have to think of a way from this code paper itself is actually because there are hints on the code paper. ”

"Hint?"

"This paper is a copy, if it is really a code drawn by the old man, there is no need to take it to the copy shop to copy, and the general copy is a rectangular A4 paper, this paper is cut, deliberately cut into a square......"

Gao Cheng looked at the old man whose face changed slightly.

The rationale for this...... What disappears after copying is the traces left by the draft, and there may even be creases, and the design of the square probably needs to be folded to unravel the code, so that the original creases cannot be left. ”

"yes!" Sato was surprised, "Is that what it means to find a way out of the cipher paper itself?" But how do you fold it? ”

"I don't know, I haven't played origami," Gao Cheng said with a smile, "Time is limited, and now is not the time to discuss this, in fact, even if you don't unlock the code, it's not that you can't find the envelope." ”

"W-What do you mean?" Yumi, who just wanted to try origami, stopped.

"You can reach the end point step by step, but you don't necessarily have to be led by the nose," Gao Cheng walked past the old man with sweat on his forehead and looked at the air conditioner that was not working, "When I first entered the room, there was still residual temperature in the room, and the air conditioner should have been turned on, but when we came, it was turned off, and the room was not turned on again after it became cold, which is one of the doubts......

"Then there is the strange request of the computer interface, which must be entered by Dianjun, that is, the American police officer who is called Cha Cha by the old man...... There would be this strange request, and it seems that there is some other reason besides the hint and the envelope clue.

"Then it's ......"

Gao Cheng smiled at the old man: "When I entered the entrance just now, the old man seemed to have unintentionally collided with Officer Yumi, on the whole, the letter should be on Yumi now, you used the usual method of stealing before, and secretly stuffed the envelope on Officer Yumi, the reason why you turned off the heater was also to prevent her from taking off her coat because it was too hot." ”

Because of the little ** pass, he noticed the old man's hands and feet at the first time, but he was not sure if he was stuffed with an envelope......

"Ahh Yumi exclaimed and took out the envelope from the inside pocket of her coat, "It's really here!" ”

"Great," Sato said happily for his friend, "The venue for the battle of the king is at the Niya Hotel in Kanagawa Prefecture, and the lunch break is until half past one in the afternoon, so there is still plenty of time, so let's get over it, Yumi!" ”

The old man's face was complicated, and he looked at Gao Cheng's gaze as if he was facing a great enemy: "Damn, I remember!" You're the detective, aren't you?! ”

"I'm sorry," Gao Cheng chuckled as he watched Yumi leave in a hurry, "However, Officer Yumi is not a chacha, just a girlfriend who Haneda Hideyoshi fought for, and is more important than any shogi." ”

Chacha, that is, Yodo-kun, Asai Chacha, the side room of Toyotomi Hideyoshi during the Warring States period of Japan, and the biological mother of Toyotomi Hideyoshi.

This old man's opinion on Cha Cha is actually very problematic, indeed, Cha Cha is known as the first evil woman in the Warring States, but this statement is quite biased and belongs to discrimination against women.

There are very few black materials for tea and tea in history, noble birth, not much to say about upbringing, and the early years were ill-fated, the elders were either executed or committed suicide, and she survived alone with a few younger sisters in the chaotic era of the Warring States period, and she was a very strong woman.

When he was forcibly accepted by Hideyoshi as a side room, Chacha's only request was for Hideyoshi to find a good family for his sisters, and after that, he loved his family in every way.

Not only is it good for his family, but Chacha also cares about his subordinates, and when Osaka Castle fell, he still cared about the safety of his maids...... Excluding other aspects, Cha Cha is not a bad girl no matter how you look at it.

Chacha is called an evil girl, the main reason is to interfere in politics, the three evil women in Japanese history basically have been involved in politics, in addition, there are some unfounded wild history anecdotes about Chacha.

After Hideyoshi's death, Chacha took his son Hideyoshi orphans and widows to power, and there were Owari factions fighting against the Omi faction inside, and the Tokugawa family was eyeing each other outside, the situation was quite complicated, and it was normal to interfere in politics, because Toyotomi Hideyori was different from Hideyoshi, and his ability was quite mediocre.

Chacha's biggest mistake was to expect too much from his son and resist the Tokugawa family for the sake of the Toyotomi family.

If in the conflict between the Toyotomi family and the Tokugawa family, Chacha finally obeyed Tokugawa Ieyasu, did not fight the Osaka battle, and gave up the country that Hideyoshi had played, he might not have the name of a wicked woman, and he would not end up burning himself with his son in Osaka Castle.

Interestingly, Chacha is generally described as a wicked woman, that is, from the Edo period when the Tokugawa family was in power, and it is even said that Chacha cuckolded Hideyoshi and was a woman, and Toyotomi Hideyoshi was not Hideyoshi's own son.

The history of the whole world is probably like this, the winner is king, and Gao Cheng, who is proficient in "Japanese history", can see it very clearly.

As for what the old man said, the vicious woman who made Taiko, that is, Toyotomi Hideyoshi, lose his ambition...... It's even more interesting, Chacha is the eldest daughter of Ashi, the first beauty of the Warring States period, and she was taken by Hideyoshi because she was very similar to her mother, and she has no room to make her own decisions.

"Humph!" The old man was dissatisfied, "You're harming Taige!" ”

"Don't talk nonsense if you don't know anything, uncle," Gao Cheng's smile remained unchanged, "Maybe you really like shogi, but Haneda Hideyoshi is not really Taiko, not Toyotomi Hideyoshi, and I'm not wrong, the reason why he wants to get together the seven crowns is because of Officer Yumi." ”

"That's right," Sato walked to the entrance and glanced at the old man speechlessly, "During the last celebrity battle, Taiko celebrities won because of Yumi, and it seems that every time they use Yumi's photo as a talisman, but it fell that day, and it still relied on Yumi's kiss...... That's what I've heard Miike say. ”

Gao Cheng stared at Sato, who suddenly explained.

Miike Miaozi, the childhood sweetheart of Chiba, has always been patrolling with Yumi, a very good girl, and she actually has gossip attributes.

Could it be that gossip is a common denominator among girls in this world? He thought that it was only the garden that gossiped with Yumi.

……

"Didn't you say you'd come over later?"

Chiba sat stupidly in the living room, watching the paused TV screen and taking another sip of water.

"It's too long, it's been more than an hour......"
