Luo Ning frowned. She had only thought that the robber sneaked in through the refrigeration passage, but where did he enter the refrigeration passage? She didn't think about it carefully.
"Leng Yan!"
While he was thinking about it, Luo Ning saw Leng Yan coming with the blueprints, and immediately waved him over. With this gesture, he really didn't regard himself as an outsider. He treated him as a big CEO, just like he treated his subordinates.
Leng Yan stepped forward funny. Luo Ning took the drawing and looked at it again. He was not polite at all. This scene almost made Qian Xuesen and others who came with Leng Yan almost be shocked. They secretly praised this policewoman for being really good.
They were so bold to treat Leng Yan, the great CEO, like this. However, Leng Yan didn't show any sign of it. Naturally, they didn't say anything more. They just looked at Luo Ning with a different look. He could treat their CEO like this, and it seemed that he
Not angry yet, the relationship between the two must be simple.
Not only Qian Xuesen, but also Zhang Shengli showed a slight surprise, but when he glanced at Qian Xuesen and others, he didn't say much, but nodded to Leng Yan as a greeting.
"I understand, the robbers did not enter the refrigeration passage from the seventh floor, but from the eighth floor. The seventh and eighth floors share a refrigeration system... The eighth floor is the clothing area, and there are only cameras in a few large passages.
, much easier to operate." After looking at the drawings again, Luo Ning suddenly said that although the Zhongyu Building uses central refrigeration, when it was originally designed, in order to save money, not every floor had a refrigeration system.
system, but adopts the design of two floors sharing one refrigeration system. It happens that the seventh and eighth floors share the same refrigeration system. Now Luo Ning finally knows why there is a refrigeration system on the eighth floor's safety passage.
There are traces of wiping. The robbers entered the refrigeration passage from the eighth floor, entered the jewelry store through the air outlet, stole the property, and then returned the same way.
Thinking of this, Luo Ning looked at Leng Yan differently. She hadn't noticed before that when Leng Yan gave her the blueprint, she folded it carefully and found out that this double-layer shared the same refrigeration system settings.
But she didn't care at the time. Looking back now, it turns out that he already knew all this.
How did he do it? Even an old detective like Zhang Shengli had no clue about a case, but he could easily see through it. This is amazing, and he himself could understand such complicated drawings. What kind of person was he?
What kind of person?
At this moment, Luo Ning was full of curiosity about Leng Yan. She realized that Leng Yan was not as simple as she imagined, nor was he an ignorant and ignorant playboy in her impression. Although he was a carefree, disgusting and rogue man, he also had real talents.
With real materials, at least in terms of analysis and judgment, and looking at drawings, there is a set of skills.
"Let's go to the eighth floor and have a look!"
Zhang Shengli greeted and everyone headed towards the eighth floor. Luo Ning was half a step behind. She looked at Leng Yan curiously. This time she did not push the drawing directly to him, but handed it to him and quickly walked
Catch up with Zhang Shengli and others.
Now that the case has a direction, it will be much easier to continue the investigation. With the veteran detective Zhang Shengli here, it only took half a day to lock in a suspect, Huang Yonggui. Huang Yonggui is the owner of a clothing store on the eighth floor. This man loves gambling.
He owes a lot of debt, and he also studied civil engineering in college. He has both the motive and the brains to commit a crime.
The police took Huang Yonggui under control and he soon confessed.
