The young lady is a detective in a vest

After finishing speaking, Qiao Luoling turned around and walked inside.However, a voice came from the door immediately, and it was very loud.This voice is not someone else's, but Zhen's happy one.

Zhen Xing was very eager and said, "Qiao Luoling! Open the door quickly! It's me!"

Hearing the voice of her best friend, Qiao Luoling immediately ran to the door of the villa, as if she saw a life-saving straw.

During this period of time, she was tortured by her mother's isolation every day, and there were a lot of things in the principal's office of Jianghe University, which weighed on her shoulders. Qiao Luoling was almost out of breath.

At this time, my best friend just came to the door by herself, so I had to have a heart-to-heart talk.

Qiao Luoling quickly opened the door, and suddenly saw Zhen Xing Xing, and ran into Xing Xing's arms.

The two returned to the living room, Qiao Luoling was still holding Zhen Xingxin's hand.

Qiao Luoling was quite strong just now, and has always been very strong, and rarely cried, but this time, Qiao Luoling was actually happy to see Zhen, and cried without saying anything.

Zhen happily reached out her hand and patted Qiao Luoling's shoulder lightly.

Zhen Xingxin patted his back while comforting Qiao Luoling: "Don't be sad any more, just let your condolences pass, and tell Principal Jiang to take care of himself."

　After hearing this, Qiao Luoling cried even harder.

Indeed, during this period of time, Qiao Luoling's heart was very painful.

On the other hand, Qiao Luoling just couldn't figure out why his brother had such a hard life!

The two chatted for a while, and suddenly Zhen happily looked around and found that the two men had disappeared.

Where did these two men go?
Zhen was happy and got up immediately.

Zhen happily searched around and came to the door of the room of the deceased Qiao Yuxuan.Dangzhen was so happy to look inside, she was dumbfounded all of a sudden.why?

Because of the scene in front of her, Zhen Xing felt a little horrified.

What is the scene in front of you?

It turned out that Bai Ziqi and Dong Hanying were fighting together, holding hands and kicking.

What are the two comparing?Are you comparing strength or fighting?Or, are two people intimate?

When thinking of this, Zhen happily shook her head, laughed, and said, "What are you two doing? Are you dancing pas de deux?"

Hearing Zhen's happy words, the two men, Bai Ziqi and Dong Hanying, quickly let go.

Why are they fighting together?

The reason was that both men came to the room of the deceased Qiao Yuxuan and checked the footprints on the floor.

Use a magnifying glass to take a picture, and use a special tool to lift the footprints on the floor.

Except for Bai Ziqi's footprints, there were no other people's footprints on the floor.why is that?
No, no!
There were indeed footprints of another person, but they were very vague, and that was the footprint of a kind of fur slipper.It can be seen that the wool slippers were worn by the deceased Qiao Yuxuan.

Excluding this kind of footprints, only Bai Ziqi's footprints remained.

And Bai Ziqi's footprints are particularly obvious, they are the footprints of leather shoes issued by the Xueyuan Road Police Station, so there is no need for testing or comparison, it is Bai Ziqi's footprints.

Besides that, there is no third kind of footprint.

So the murderer has no footprints?
Is the murderer really a ghost?
Floating in through the window, avoiding all monitoring, of course ghosts can't see it, so flying in and killing people, and then leaving quickly?
And without leaving any traces?

Both Bai Ziqi and Dong Hanying found it incredible.

Especially Dong Hanying looked at Bai Ziqi suspiciously and said, "Bai Ziqi, there are only your footprints on the ground, so the murderer must be you!"

After Bai Ziqi heard it, she immediately became very angry: "Dong Hanying! What are you talking about?!"

"I said, you are the murderer!" Dong Hanying pointed at him without hesitation.

"Others can doubt me, but you can't doubt me!" Bai Ziqi was furious.

Dong Hanying sneered and said, "Why?"

"You!" Bai Ziqi gritted her teeth angrily, and stared at him fiercely.

Unexpectedly, Dong Hanying made another cut.

"Bai Ziqi, I don't mean to doubt you now. I just think that besides the deceased Qiao Yuxuan's footprints, there are only your footprints. To say you are the murderer is my normal reasoning, do you know?"

Dong Hanying is not suspicious anymore, it is certain.

The more Bai Ziqi heard it, the more unhappy she became.

At first I thought that Dong Hanying had always been skeptical, but now Dong Hanying actually said that he was sure.

Bai Ziqi immediately raised his hand, wanting to hit someone.

Dong Hanying also raised her hand, and immediately grabbed Bai Ziqi's arm.

Bai Ziqi felt very painful, and immediately grabbed Dong Hanying's arm with her other hand.

Similarly, Dong Hanying also felt extremely painful.

Specifically, both Bai Ziqi and Dong Hanying couldn't move their four hands.

You grab my arm and I grab yours.You grab my wrist, and I grab your wrist, and then, the only thing that can move is the feet.

Bai Ziqi is agile, but Dong Hanying's skill will not lose to Bai Ziqi at all.

The two started to move their feet.Dong Hanying pushed Bai Ziqi's right foot with her left foot.Bai Ziqi stretched out her left foot against Dong Hanying's right foot.

The two of them have been competing there for the strength of their feet, and whoever has more strength will be able to survive.

As a result, they continued to resist tenaciously until Zhen Gaoxing appeared at the door of the deceased Qiao Yuxuan's room, and Bai Ziqi and Dong Hanying did not let go.

After letting go, Dong Hanying felt her whole body tingling; Bai Ziqi also felt very uncomfortable and her whole body was stiff.

Zhen happily watched them separate before walking in.

Seeing that neither of them spoke, Zhen Xing put his hands on his chest and looked at Bai Ziqi.

I saw Bai Ziqi's bewildered face, she pouted, but didn't speak.Dong Hanying didn't bother to talk to Bai Ziqi, and he didn't even say a word.

Zhen happily shook her head, smiled wryly, and said, "What do you two mean?"

Dong Hanying still didn't speak.

Bai Ziqi immediately turned her head and looked at Zhen Xingxin confidently. He was sure that Zhen Xingxin would believe what he said.

Full of confidence, Bai Ziqi immediately said, "Happy, do you know what Dong Hanying said to me?"

Zhen nodded happily, and said, "Tell me, let me see who makes sense!"

Bai Ziqi was very confident, looked at Zhen happily, and said, "He actually suspected that I was the murderer. Because there are only my footprints and the fuzzy footprints of the deceased Qiao Yuxuan's fur slippers in this room. Strictly speaking, I am the only one." Human footprints are complete."

When Zhen was happy to hear that, she immediately stared at Bai Ziqi with suspicious eyes.Then, without speaking for a long time, she turned around slowly and looked at Dong Hanying.Dong Hanying nodded vigorously.

Seeing the actions of the two of them, Bai Ziqi suddenly became very annoyed.Bai Ziqi was really angry.

Before saying this, he was very confident.He thought that Zhen Xing would be on his side, but now he didn't.

All right!Since Zhen is happy and believes what you said, then I have to explain the professional knowledge.

Bai Ziqi coughed twice, successfully attracting the attention of Zhen Xingxin and Dong Hanying.

Zhen Xingxin and Dong Hanying turned to look at Bai Ziqi at the same time.

Bai Ziqi looked at Zhen Xing Xing, he was very concerned about Zhen Xing Xing's expression and eyes.

At this time, Zhen Xingxin really looked at Bai Ziqi seriously.

Hearing Bai Ziqi's cough, Zhen knew what Bai Ziqi wanted to say when she was happy.

Because it's always been that way.

Before Bai Ziqi made a speech, she used to cough twice to attract everyone's attention.It's like talking on the radio and suddenly playing some music to attract the attention of others.

Zhen Gao just looked at Bai Ziqi like this, and didn't say a word, not much.

Of course Dong Hanying didn't want to talk either.Mainly because she doesn't like talking to Bai Ziqi.

Because Dong Hanying felt that based on his own judgment and these useful evidences, it was indeed Bai Ziqi who was suspected of correct reasoning.However, Bai Ziqi actually doubted and denied it out of feelings.

That is to say, when investigating the case, Bai Ziqi actually got mixed up with personal feelings.

When investigating a case, what is important is the evidence. There are Bai Ziqi's footprints on it, which means that the murderer may be Bai Ziqi.It's normal to suspect him.However, Bai Ziqi didn't think so.

Bai Ziqi felt that if he was a brother, he shouldn't doubt him.

So neither is wrong.It's just that the starting point of the two people is different.

Bai Ziqi coughed twice, and said frankly, "You two, do you think that the presence of my footprints on the ground proves that I am the murderer?"

Zhen happily tilted her head, very puzzled, and said, "Isn't it?"

On the floor of the room, I found your footprints, and then there are the vague footprints of the deceased himself, which shows that the murderer is very likely to be you.Since there is no third footprint, how do you explain it?

When Bai Ziqi heard this, she felt even more uncomfortable.However, Bai Ziqi still had to use professional knowledge to explain and prove her innocence.

Bai Ziqi was very wronged, but she responded rationally: "I'm glad, you are still a detective no matter what. Although your business is not very good, you should know some basic knowledge."

Hearing Bai Ziqi's words, Zhen Xing became very unhappy.How to go?Now that you yourself are a suspect, you are still educating me?Are you even laughing at me for not having a business?Where do I have no business?I'm just helping you investigate the case for free, for whom?Isn't it for you?Zhen was so happy that she couldn't express her grievances.

Zhen happily smiled bitterly, and said, "Why don't I understand? Tell me! How much do you understand!"

Zhen Xingxing glared at Bai Ziqi very unhappy, as if she must listen to Bai Ziqi's explanation!
Bai Ziqi was very confident, nodded, smiled, and said calmly, "Happy, have you forgotten that under normal circumstances, a professional killer will not show any flaws."

Zhen Gaoxin pressed him with a puzzled face.

"That is to say, he will not leave any fingerprints or footprints wherever he passes." Bai Ziqi continued to answer professionally.

After Zhen was happy to hear it, she rested her cheeks and thought, why?
Zhenxin immediately turned her head to look at Bai Ziqi's puzzled face, and said, "Bai Ziqi, how did the murderer come to the deceased Qiao Yuxuan's room?"

If he wants to kill someone, he has to stand somewhere, right?

He was going to pass through the room, and even if he escaped from the window, his feet should also be on the window, right?
Or he crawled over it, but when he got down, his toes should touch the ground, right?

Bai Ziqi pointed to another footprint on the ground, and through the magnifying glass, Zhen was delighted to see a blurred footprint.Specifically, it doesn't look like a footprint.why?

Because it was the footprint of a pair of fur slippers, which was very incomplete.

Zhen Xingxin didn't know what Bai Ziqi asked her to watch.

She dismissively pushed away the magnifying glass.
