At this time, I heard Chen Ying say again: "According to my previous estimate, the murderer only needs to survive the second moment of Zichu to the first moment of Zizheng, and this game will be completed." And he chose this time to commit the murder, and it was expected that during this time period, there would be no night watchman. ”

Pei Shu nodded with a calm face: "This fang is extremely cunning. He knew that the guards and servants on duty at night were divided into two shifts, and the second quarter of the first month was the time for the shift. ”

"That's it." Chen Ying's voice was calm and calm: "The murderer is bold and careful, and he anticipates the enemy first, and he does have some means, but Ah Shu doesn't have to be discouraged." ”

She looked at Pei Shu, and her eyes danced with a star-like glow: "No matter how bold and careful the murderer is, he will finally show his feet." For example, the words I just said out loud are a precept for medicine. ”

"What do you mean by that?" Pei Shu looked at her in confusion, his eyebrows twisted into knots: "I thought that you just turned over and over and said loudly that this case was an accident, and you couldn't find any clues, and you were confusing the real murderer hiding in the mansion, didn't you?" ”

Chen Ying let out a "hmm", admitted his speculation, and said: "From the perspective of probability, it is relatively common for the murderer to return to the scene after the crime and observe everyone's reactions as a bystander, so as to obtain a strange psychological satisfaction. Naturally, in this case, the murderer should have obtained this satisfaction earlier, but, it didn't take long for me to suddenly appear. ”

She slowed down her speech and showed her usual smile on her face: "Even if the murderer didn't know who I was before, at this moment, he must have known about it. And my words should soon reach their ears. If I were the murderer, what would I do after learning all this? ”

She turned her eyes to look at Pei Shu, and her smile became more and more strange: "I think that from today onwards, I will ignore this case and be a man with my tail between my legs." Because any superfluous things and superfluous words will bring danger, after all, there are still better stories of my detective. ”

At this point, her smile deepened: "In this way, Ah Shu only has to make a list of people who appeared at the scene after the crime and then didn't pay attention to the case, and there is a seventy percent chance that the murderer will be framed." ”

"I see." Pei Shu said thoughtfully.

Chen Ying thought for a while and added: "Also, if someone didn't live in that compound originally, but came to watch after the crime, Ah Shu also needs to pay attention to this kind of person." ”

"It doesn't have to be." Pei Shu shook his head and frowned two long eyebrows: "I wanted to say it since I first started, the scope of the murder suspect can be narrowed down a little more." The murderer could only be someone from that compound. ”

"Oh?" Chen Ying was a little surprised: "How do you say this?" ”

Pei Shu tilted the corner of his lips, and his smile was a little strange: "Just now, when we went back and forth between the main house and the courtyard where the crime occurred, you should have noticed that this road has to pass through two courtyards. ”

"That's true." Chen Ying said, frowning lightly: "In this way, the two places are quite far away." ”

"It's a long way off." Pei Shudao, his smile changed, and he actually laughed at himself: "Because, the two courtyards in the middle are uninhabited at all, and they are guarded by secret guards day and night." I'm afraid that someone will sneak in and assassinate Qian Tianxia, so I put all the people on the periphery. ”

He slowly lowered his head, and the corners of his lips hooked a bitter arc: "It's just that I have tried to guard against it, but I only guard against the outside and not the inside, and I still let the ghost inside." ”

Chen Ying disagrees.

"I think it's a blessing in the midst of misfortune." Her face was relaxed, and even a little happy: "If the scope of suspicion is narrowed, the possibility of catching the murderer is greatly increased, and it can take less time to screen the suspect." ”

"I hope so." Pei Shu twisted out a smile vigorously, obviously not wanting Chen Ying to worry, but quickly cheered up again, and said: "Those secret guards are not bad, and they are in groups of three and monitor each other, I think the possibility of a murderer among them is low." And with them, the murderer could not sneak in from the outside, only the people in the compound. ”

Chen Ying nodded silently.

According to Pei Shu, one thing can be reversed:

The murderer should not be a guard.

Even the secret guards are in groups of three, monitoring each other, presumably the same is true of the night guards, if the murderer is one of them, whether on duty or not, the movement will be greatly restricted, and the possibility is very small.

Thinking about this, Chen Ying asked Pei Shu again: "Does Ah Shu have anyone he can trust?" ”

"Yes." Pei Shu said immediately, his eyes became cold again: "Why did Ah Ying ask this?" ”

Chen Ying said: "I have a method to quickly identify the murderer, but this method is only suitable for a small number of people. ”

She stared at Pei Shu with a solemn expression: "The first thing Ah Shu has to do is to lock the suspects in single digits - that is, no more than ten people. Within this range of people, my method is feasible, otherwise the scope is too large, and it is easy to lose sight of one or the other. ”

When Pei Shu heard this, he subconsciously went to hold the hilt of the sword, and his long eyebrows loosened slightly: "Don't hide it from Ah Ying, I am also worried about this, and I want to ask you to solve your doubts." ”

"It's actually not difficult, there's a logical reason, just use it." Chen Ying smiled, raised his hand and lightly swept his temples: "Earlier you said that something happened to Penglai, let's make a fuss about it, you just need to ...... like this"

She leaned into Pei Shu's ear, whispered a paragraph, and finally took a few steps back, looking up at him with a smile: "When this word spreads, you just have to send someone to keep an eye on the suspect, whoever can't hold his breath will be the murderer." ”

Pei Shu only nodded again and again, admiring and delighted, and was about to speak, when a commotion suddenly came, mixed with Lang Tingyu's loud voice.

"Lord Chen, Lord Chen, you walk slowly, this road is very slippery, and I will help you later." As he spoke, the sound of chaotic footsteps came and went, and he was already outside the curtain.

With a "whoosh", Lang Tingyu probed in, quickly scanned the situation in the house with lightning speed, and then his face relaxed, turned around and opened the door curtain, and spoke so loudly that it could collapse the beams:

"Master Hou, Master Chen, Lord Chen has arrived-"

The voice is as rough as an old duck, and it drags up a long note, which is full of twists and turns, and the waves are magnificent, which can simply lift people a few times.

Lang Tingyu didn't notice it, desperately squeezing his eyebrows at Pei Shu, and his eyes rolled so much that he almost couldn't come back.

Pei Shu glared at him with a dark face, and before he could say more, he strode forward, and a tall figure had already stepped into the door, the fiery red official robe was scorching, and the aura of a cold bamboo was lined with a cold atmosphere, and the house was bright and cold.

"The little nephew has seen Shibo." Pei Shu bowed and saluted, with a face that was always a little arrogant, and he was already twelve points solemn at the moment.

He was answered with a heavy "hum".

The person who came was Chen Shao.
