In an instant, Qi Wanli thought a lot.

Yan Baichuan, the old housekeeper, knew through the dark yuan when he saw it for the first time, this is a hidden master, a martial artist, with the strength of a sixth-order mid-stage Xuanjia master, but it seems that he suffered a lot of injuries in his early years, and there are many dark diseases in his body.

Of course, this is not important, the important thing is that from the perspective of Yan Kai calling the old housekeeper "Uncle Baichuan", this old housekeeper should have been in the Yan family for many, many years, and may even have watched the current brothers and sisters of the Yan family grow up, and he has enough emotional motivation to keep the weakest and most helpless fourth lady in the family.

And, he has that ability.

The old housekeeper of the Yan family has the ability to send people out in the layers of encirclement of the family, and at the same time, he also has the strength to highlight the encirclement under special circumstances.

Of course, Yan Baichuan's momentary emotional fluctuations don't prove anything, and it is impossible for Qi Wanli to run to the old housekeeper in private to solve this matter in a daze.

It can only be said that with a breakthrough, everything is easy to do.

Qi Wanli remained silent, and continued to chat with Yan Kai, and after Bao Youwei and Wang Lu arrived, they turned the topic to exchange cultivation experiences, and as "Bai Yao", they pointed them out.

It wasn't until late at night that they went back to their rooms that Qi Wanli really started his investigation.

He put on his mask, changed into loose-fitting clothes, walked into the garden, lit a cigarette, and walked leisurely.

Through Dark Yuan, he already knew that Yan Baichuan was in front of the garden at this time, and he didn't know what he was doing.

Sure enough, after not walking a few steps, he could see the old housekeeper squatting among the flowers, facing him sideways, and was busy with his head down.

"It turned out to be Dean Bai. ”

Yan Baichuan stood up without changing his face and saluted respectfully, but Qi Wanli could clearly feel that the attitude of this old housekeeper was different from when they first met in the morning, and there was a trace of indifferent estrangement.

Qi Wanli didn't care, he smiled, stepped forward, said hello and asked, "I can't sleep and come out for a walk...... What is Steward Yan doing?"

"This flower bed is Miss Four's favorite flower bed before her death, every flower was planted by her own hands, and the small one is just to take care of Miss Four. Yan Baichuan said lightly.

"Steward Yan really has a heart. Qi Wanli said with a smile: "It just so happens that the dean of this country also promised Uncle Xiaoguo to help check the whereabouts of the maid, I wonder if Steward Yan can help?"

"Dean Bai, please speak. Yan Baichuan bowed his head slightly.

Qi Wanli said: "It's nothing, I just want to see where the maid used to live, see if she has any common things, and learn about her daily habits, which will be very helpful for me to judge her thinking habits." ”

Yan Baichuan hesitated.

"That's right. Qi Wanli didn't wait for him to respond, and continued to ask, "What's the name of that maid?" ”

Yan Baichuan frowned and said, "Her name is Xiaoya...... She is Miss Four's personal maid, and she usually lives in the same room with Miss Four. ”

Qi Wanli smiled: "Please lead the way with Steward Yan." ”

Yan Baichuan hesitated for another half a second, and could only lead Qi Wanli forward.

Judging from the scanning analysis results provided by Dark Yuan, this old butler's heartbeat accelerated slightly, and his breathing was only so rapid for 0.25 seconds, and then he was suppressed by his powerful body control ability of a sixth-order martial artist.

It can be said that he completely controlled his expressions and movements, and that hesitation was reasonable, and normally speaking, no one could see anything wrong from his performance.

But no matter how powerful he is, it is absolutely impossible to imagine that Qi Wanli has the means to monitor such subtle and in-depth changes in himself!

Along the way, Qi Wanli quickly threw a few questions lightly, and Yan Baichuan answered them all fluently, but Qi Wanli was already confident.

This Yan Baichuan housekeeper should answer completely according to the answers given by the Yan family, all the answers have almost no loopholes, and all of them can be logical and self-consistent.

Even after a few months have passed, Qi Wanli can completely imagine how the Yan family has arranged everything, and it is impossible to find out any clues at any time and when anyone comes.

But Qi Wanli is different, he is a person who has known the answer for a long time, but he just deduces the process of solving the problem from the answer.

Xiao Si, that is, Yan Zhiyi's original room, is also on the fourth floor, at the end of a separate corridor, with the door locked.

"Dean Bai, do you need to call the other family members and maids for questioning?" Yan Baichuan asked without a trace.

Qi Wanli smiled and shook his head: "People's memories can go wrong, but things don't. ”

After the door opened, he swept around from left to right, and the dark element had already completed the analysis. However, of course, he can't just look at this and start asking, it's too fake.

So, Qi Wanli touched left and right, as if he was seriously investigating the case.

This room is very large, more than 100 square meters, it is a huge suite with a side bedroom, according to Yan Baichuan, that is the residence of "maid Xiaoya", but Qi Wanli only glanced at it, and knew that it was cleaned up later, and everything was arranged later, not the original appearance.

He walked in, and after groping for a while, he blinked and asked, "Steward Yan, can I ask you a few questions?"

"Dean Bai, please ask. Yan Baichuan bowed his head.

Qi Wanli casually played with some of the knick-knacks in the side bedroom, and asked, "Where did the case happen at that time?"

Yan Baichuan said: "In the fourth lady's house, the gangsters broke through the window, cut the throat of the fourth miss, and then escaped through this window. ”

"This is the scene of the crime, and the scene has not changed?"

"No, after the yamen investigated the case at that time, the fifth master ordered this room to be sealed off because of sadness, and no one was allowed to enter or leave, and he was not usually allowed to talk about this matter. ”

"How did Xiaoya escape at that time?"

She was frightened, screaming and running out, there was chaos in the house at that time, everyone's attention was on the fourth lady's side, no one paid attention to her, and when everyone reacted to ask her, she had disappeared, and when she asked later, she knew that she had escaped from the house. ”

Qi Wanli looked at the broken small window with his hands behind his back, and then looked at the unwashed blood stains splashed on the wall and the ground, and shook his head.

"Steward Yan, where and what were you doing at the time?"

Yan Baichuan frowned: "Dean Bai, what was the little one doing at that time, does it matter?"

"Hehe, ask casually, I just want to see if you have any clues, Steward Yan. Qi Wanli smiled and said, "If you remember, tell me, it doesn't hurt." ”

Yan Baichuan sighed and said: "At that time, the second master was heartbroken and almost unconscious, the little one was assigning someone to take care of the second master, and the fifth master was in a hurry to enter the palace to report to the queen, and let the little one arrange the carriage. ”

"Really?" Qi Wanli asked with a smile, "Then who went after the murderer at that time?"

Yan Baichuan replied: "It's our Yan Mansion's secret envoy......"

"Oh, but I heard that it was the Yamen who solved the case?" Qi Wanli said with a smile: "According to the information I heard from Uncle Xiaoguo, that murderer is a bold fourth-order Sky Walker, although his strength is good, it is barely possible to sneak into the Yan Mansion, but after killing the fourth miss, he can actually escape from the pursuit of your Yan Mansion's powerful secret envoy team?

Yan Baichuan was stagnant.

Qi Wanli didn't give him a chance to think at all, and immediately asked, "Who is the leader of your secret envoys, I want to see him." ”

Yan Baichuan said: "It's Wei Ping'an, he went to look for Xiaoya......

"Find a maid to ask for a powerful envoy?And now this maid is most likely in the capital, and a large group of secret envoys of your Yan Mansion can't find her?" Qi Wanli asked: "Is the secret envoy raised by your Yan Mansion too weak, or is this maid actually a hidden anti-investigation master?"

Without waiting for Yan Baichuan to speak, Qi Wanli took a step towards him, frowned, his voice was amplified by three points, and asked: "You said that you arranged miscellaneous things in the mansion at that time, but those trivial matters don't need to be ordered by your old housekeeper Yan personally, you are a person who has carefully taken care of the fourth lady's flower bed for months after her death, and you are also a sixth-order master, will you let her murderer escape?"

Yan Baichuan didn't expect Qi Wanli to break his strength, he was shocked in his heart, and subconsciously retorted to the question behind him: "I don't have ......"

"You didn't, that means you went to chase it?" Qi Wanli narrowed his eyes: "The dignified sixth-order Xuanjia master, plus a group of secret envoy masters, can't even catch up with a fourth-order murderer?"

"You said that the scene of the crime here has not been touched, but the blood stains are splashed in the direction of the window, extending to the edge of the window, if the gangster is breaking through the window, killing people and then escaping through the window, even if he dodges the splash of blood, it is impossible to completely avoid stepping on or touching the bloodstains when leaving, but these bloodstains are not defective, they are natural, if it is a throat cut, it should be a throat cut from behind, and it is from the door, these bloodstains will be so perfect. ”

"Yan Baichuan, you're lying to me. ”

The more Qi Wanli spoke, the colder his voice became, and his eyes bloomed with a light that shocked Yan Baichuan, a sixth-order Xuanjia Master, as if he had completely seen him through!

"Dean Bai, there is no evidence for empty words, please be cautious. Yan Baichuan said astringently.

Qi Wanli squinted again.

"Really?" he sneered, "Is there no basis for empty words? Then please answer my question above, why can you mobilize a group of secret envoys at any time in your Yan Mansion, but you can't prevent a fourth-order murderer?"

"If you can't answer, I can only think that you Yan Baichuan has a problem, you murdered the fourth lady, and made up so many reasons to fool others, and killed Xiaoya, the only maid who witnessed the incident, creating the illusion that she was hiding...... In that case, why do you still take care of the flower bed for Miss Four? is it because of guilt?"

"Or is that Xiaoya actually your person at all, the person you placed next to Miss Four, and after cooperating with you to kill someone, she was hidden by you?"

In fact, he is talking nonsense, including the reasoning above, which is nothing more than the reasoning process made up through some clues after knowing the result. Even if it is a real detective, it is impossible to immediately deduce the real result when he sees some traces like in those movies, and Qi Wanli does not have this ability, the most powerful criminal police detective he has ever seen, also needs to use a lot of tools to really achieve perfect reasoning.

"Don't talk nonsense!"

Yan Baichuan was finally angry, his eyes were full of anger, and the murderous aura on his body appeared!

"Hey, old housekeeper Yan, what's the matter with you. Qi Wanli sneered: "Even if what I said is true, you don't have to be so excited, right? You are a conspirator for doing these things, is it so unprofessional?"
