"Where do you get your confidence?" Dong Bingning looked at Ye Yinuo a little speechlessly, Ye Yinuo's statement was indeed a bit appalling.

Ye Yinuo didn't speak, and Wang Han asked suspiciously, "Do you have any important clues that you haven't told us?" ”

"I know, you all know, I don't know, you know, now I just need to know what you know." Ye Yinuo said, turned his head to look at Wang Han and said, "Team Wang, what name are you going to use to involve me in the case?" ”

Wang Han raised his hand and looked at his watch and said, "It's half past two, and it's still too late, I'll take you to meet someone now." ”

"Who?" Ye Yinuo asked suspiciously.

Wang Han said two words: "Gu Lao." ”

"Old Gu? Gu Chengwu? Dong Bingning's face was shocked.

Gu Lao, formerly known as Gu Chengwu, is one of the top two titans in the criminal investigation industry, a native of Qingyu City, one of the first batch of specially invited criminal investigation experts of the Ministry of Public Security, a bureau-level investigator of the Ministry of Public Security, and a senior engineer in criminal technology.

Ye Yinuo is also no stranger to Gu Chengwu, and the people who have been in contact with him through the computer dialogue window have mentioned Gu Chengwu, and the mysterious person who has never met Gu Chengwu should know each other.

Ye Yinuo can also understand Wang Han's thoughts, although Gu Chengwu is now old and has withdrawn from the front line, but if he is a guarantee in his name and recommends an expert to assist the police in handling the case, there is no problem at all, of course, the premise is that the background of the recommended person must be white, which is why Wang Han insisted on Ye Yinuo to clear the suspicion first.

"Well, time is pressing, we'll go now, and we'll be back by four o'clock." Wang Han said and walked outside.

Dong Bingning quickly followed, and asked, "Team Wang, are you planning to hire Ye Yinuo into the detachment in the name of a specially invited expert?" ”

Wang Han nodded and didn't speak, Ye Yinuo also followed quickly, Dong Bingning continued: "But even if you want to hire specially invited experts, you need the consent of the municipal bureau. ”

"That's why I'm looking for Gu Lao." Wang Han said that he had already walked down the detachment office building and came to his off-road vehicle.

Ye Yinuo didn't speak, just sat in the co-pilot, and he didn't need to worry about these things.

"You're watching in the team, call me anytime if there's any situation." Wang Han said and took out the police alarm and put it on the roof of the car, directly turned on the alarm bell, and quickly drove away from the Xicheng detachment.

The alarm bell is loud all the way, the vehicles on the road have given way, less than half an hour, the car is parked outside an old-fashioned villa on the border of Xicheng District, the villa area is not large, it is not luxurious, if it is placed in the countryside, it is an ordinary three-story small building, but it is in the urban area, and there is a small courtyard, it is called a villa.

"Get out of the car, wait for Gu Lao to ask you some questions, you answer truthfully, don't lie, Gu Lao is not only excellent in criminal investigation skills, but also a top psychology expert, if he doesn't like you, I can't help it." Wang Han looked at Ye Yinuo and said, he didn't open the car door in a hurry, it seemed that he was waiting for Ye Yinuo to make a statement.

Ye Yinuo nodded, smiled lightly and said, "I know, don't worry, let's just go to see Gu Lao empty-handed?" ”

"This is our official business, bringing things will become bribery, Gu Lao has been honest all his life, I want to carry things, I have to drive the two of us out." Wang Han unlocked the car at this time, and the two got out of the car at the same time.

Wang Han tidied up his clothes, walked to the gate of the courtyard wall, and rang the doorbell.

"Click!"

The door lock opened, it seemed to be an electronically controlled door lock, Wang Han pushed the door and walked in, and saw an old woman about seventy years old was taking care of a small vegetable garden in the yard, she was sitting on a small chair, and was distributing some seeds for spring ploughing.

The vegetable garden is planted with leeks, white radish, tomatoes, eggplants, and even a wooden shelf, on which there are many winter melon vines, and the winter melons on it are only just blooming.

Seeing Wang Han and Ye Yinuo coming in, the old woman smiled and stood up and said, "Hehe, Wang Han, you haven't been here for a long time." ”

Wang Han walked up quickly and said respectfully: "Master, the student is busy with work, and he has not been able to find time to see his wife and teacher, and he asked his wife to punish him." ”

"Understand and understand, when you become the captain, the work tasks and responsibilities are different, since you are here today, I will prepare a meal, dinner will be eaten here, and you will also accompany you Teacher Gu to have a good chat." The old woman said.

Wang Han hurriedly said: "Master, I came here today for business, and I will go back in a while, so I should not be open, I will visit again when I am free another day." ”

"Okay, okay, then you can go quickly, you Teacher Gu is in the study." The old woman is also very understanding.

Wang Han and Ye Yinuo thanked the old woman, and walked into the hall door of the villa quickly, the decoration of the house is a little quaint, many old photos are hung on the wall, the living room is still a very old TV, without any luxury and exquisiteness, the overall decoration and furnishings are very simple and simple, giving people the first feeling that the family is not rich, and even a little poor.

Wang Han seemed to be very familiar with this villa, turned left and went upstairs, and then turned right to the door of a room.

"Tuk Tuk Tuk" Wang Han knocked softly three times, "Teacher Gu, are you there?" I'm Wang Han. ”

An old voice came from inside: "Come in, the door is unlocked." ”

Wang Han pushed open the door and walked in with Ye Yinuo, and saw a lean old man with gray hair and wearing a Tang costume fiddling with a chess endgame, he turned his back to the door, and asked without raising his head: "Wang Han, do you have nothing to do but go to the Three Treasures Palace, do you have something to ask for?" ”

"Teacher, the student is ashamed, I hope I didn't disturb the teacher Yaxing......" Even though he was the captain of a criminal investigation detachment, he seemed extremely well-behaved in front of Gu Lao, he rushed over in a hurry, and really saw Gu Chengwu, no matter how anxious he was, he didn't dare to show it.

Gu Chengwu still didn't look back, and said in his mouth: "Young man, come, help me see this endgame." ”

"Teacher......" Wang Han said in a low voice, but as soon as he shouted, Gu Lao raised his hand to stop him from continuing: "You have something to say later." ”

Ye Yinuo was also stunned, but there was a monitoring screen in the room, and the screen could see the outside, and from the time they came in, Gu Chengwu already knew that they were two people.

"What are you doing, the teacher told you to come over, go quickly." Wang Han said a little eagerly, he didn't dare to be anxious with Gu Chengwu, but he didn't have that much respect for Ye Yinuo.

Ye Yinuo nodded and walked over, glancing at the chessboard.

There are no more than five flags on the chessboard, with Red having a commander and a cannon and a pawn, with the commander in the center and the cannon in the center of the red side with a foot, and the pawn further and Black's center with a foot.

Black has only two discs, right in the center and right in place.

In Ye Yinuo's view, this is a typical small endgame for Black, and Red must win, but it is just a matter of the number of moves.

Just saw the chess game clearly, but in two seconds, Gu Chengwu raised his hand and swept away the chess pieces on the chessboard and said: "This is a game where artillery forbids a single elephant, red moves first, within ten moves, can red ban black?" ”

The so-called forbidden chess is to make Black have no way to move, and any move he makes is a self-general, and it becomes a dead move.

Ye Yinuo's head thought quickly, and it was only two seconds, and he said directly: "Nine steps is enough." ”

"Oh? Hehe...... Let's talk about it. Gu Chengwu looked up at Ye Yinuo, Ye Yinuo saw Gu Chengwu's appearance clearly, Gu Chengwu's appearance is very ordinary, and his face can't stand the years of suffering, and there are many age spots, the forehead lines on his forehead are staggered, the nose is very large, the skin on his face is loose, and he is engraved with the vicissitudes of history, but a pair of eyes are bright, which makes people feel that there is a bottomless world in these eyes.

Wang Han was a little nervous at this time, he knew Gu Lao's temper, Ye Yinuo's words were a little big, he also knew a little bit about chess, but this kind of endgame that could not be deduced on the chessboard, and it also stipulated nine moves, there were too many combination algorithms in it, not a professional, it was difficult to say it directly, even if it was a professional, there was no way to do it in just a few seconds.

It turned out that Wang Han's worries were superfluous, Ye Yinuo just spoke directly in less than two seconds after Gu Chengwu finished speaking: "Gu Lao, that kid is ugly, the red side will go first, the cannon will be five and eight, the black side will not move like an elephant, it can only be four and five, and in the next move, Black is passive, so I won't say how Black moves, I will say how to move Red." ”

"Interesting, let's talk about it." Gu Chengwu nodded, and there was already a trace of affirmation in his eyes.

"Pawn five into six, pawn six into one, cannon eight into four, cannon eight into six, handsome four back one, pawn six into one, cannon six into eight, cannon eight into two, forbidden chess, black elephant heart is stuck, shogi can not face handsome, any step is a self-general." Ye Yinuo said, as if he was reciting a mantra, his thinking was unusually clear, and his language was even more fluent, which seemed to Wang Han to hear, and he hadn't even figured out how to go.

Gu Chengwu smiled and said, "It's really good, come and sit, set up chess, let's play a game." ”

Hearing Gu Chengwu say that Gu Lao wanted to play a game, he was even more anxious, the game time can be long or short, and now there are so many things in the team, he doesn't have the heart to watch Ye Yinuo and Gu Lao play chess here.

Gu Chengwu's thoughts, Gu Lao naturally understood, he said while playing chess: "Wang Han, go make tea, no matter what happens, you can't be in a hurry, you are the captain of the criminal investigation team, your heart should be more calm......"

After listening to this, Wang Han also nodded silently, but there were thousands of teddies galloping in his heart, but Ye Yinuo said respectfully: "Gu Lao, my name is Ye Yinuo, since Gu Lao has this Yaxing, the kid will accompany you." ”
