"The wrong direction of investigation?!"

Han Bing was slightly stunned and asked puzzled, "Jiarong, what do you mean by this?!"

"In the past few days, when our comrades-in-arms searched the whole city, who were the people who were focused on investigating?!"

Lin Yu asked rhetorically.

"Of course, it's those fifty or sixty-year-old old men, and the slightly hunchbacked ones are the most important targets for investigation!"

Han Bing said in a deep voice.

"Yes, that's it, maybe we checked the wrong person in the first place!"

Lin Yu said in a solemn voice.

"But isn't that what you described to us, that this killer is an old man of fifty or sixty years old!"

Han Bing asked in some surprise.

"Yes, it dawned on me that maybe I was wrong with the message I was sending you in the first place!"

Lin Yu said in a deep voice, "Perhaps, that killer is not an old man at all!"

"You mean, that peddler lied to you?!"

Han Bing on the other end of the phone couldn't help but be stunned, she knew that there was information about the appearance of this killer, and it was Lin Yu told by a hawker.

"There is no problem with the identity of that vendor, he is indeed an early seller, and he has been working on the street for more than ten years, he should be telling the truth!"

Lin Yu said in a deep voice, "It's just that the old man who went to deliver the letter to him may not be the killer, maybe it is just an old man hired by the killer!"

"But didn't you listen to the peddler that this old man walks fast and is very energetic, unlike ordinary people!"

Han Bing was puzzled.

"Yes, it was because of this that I subconsciously decided that this old man was the killer!"

Lin Yu frowned and said, "But it's also possible that this old man has practiced martial arts, or likes to exercise on weekdays? In the eyes of the peddler, it is very different, after all, that peddler is just an ordinary person! And this may be exactly what the killer can create, just to make us mistakenly think that he is this fifty or sixty-year-old old man, after all, from the age of the calculation, the old man's identity is most likely to match him!"

It wasn't until this moment that Lin Yu realized his mistake, and after hearing the peddler's description, he subconsciously made up his mind for this killer.

"If it's true as you said, this killer is not an old man, then how should we focus on the investigation next?!"

Han Bing asked in a low voice, "You can't always focus on the investigation of men, women, old and young, there are so many people, you can't investigate it at all......

They have spent a lot of time and energy on a general survey of the population in the entire urban area, and the energy and time spent on the key investigation will only increase exponentially!

It is simply impossible to complete it in a short time!

"I don't know ......"

Lin Yu couldn't help but sigh, his brows furrowed, and his face couldn't help but be covered with a layer of sadness.

At this moment, he didn't know what to do, because everything about this killer was a mystery!

And now that time is limited, this killer only gave him less than three days, and as soon as the day after tomorrow passes, maybe this killer will strike immediately.

No one knows what he will face in three days.

"This killer is really not in vain, we have searched the whole city for so many days, and we haven't even found any information about him!"

Han Bing on the other end of the phone couldn't help but shake her head and smile bitterly, at this moment, she also admitted that the world's number one killer was indeed more difficult to deal with than the "devil's shadow" who was ranked second in the world at the beginning.

"Don't worry, it's the fox who has to show its tail sooner or later!"

Lin Yu said in a deep voice, "Maybe under such a strong search, he can't bear it anymore, and now is the time for the two of us to compete for endurance!"

"Okay, then I'll notify me now, and then adjust the object of the investigation, and no longer focus on the elderly man!"

Han Bing said in a deep voice, "Instead, focus on investigating people who look suspicious, whether they are men, women, young or old, whether they are Chinese or foreigners!"

"Yes!"

Lin Yu nodded solemnly, "It's hard work for me and my brothers, and I will be grateful to He Jiarong afterwards!"

After hanging up the phone, Lin Yu pondered on the balcony for a while, and after his mother and Jiang Yan and the others got up, he emphasized to his mother and mother-in-law again that he must not go out in the past few days!

Of course, including Ye Qingmei, Jiajia and Yin Er, they all asked for leave at home and were not allowed to go out for a single step!

Although the family was a little unclear, seeing Lin Yu's expression was so solemn, they all agreed seriously.

Soon, three days passed in a flash, and after three o'clock in the afternoon, it was past the last time node given by the number one killer, Lin Yu suddenly became nervous, and kept walking back and forth on the balconies on the north and south sides to observe the situation below the community.

And the people from the Military Aircraft Department also strengthened the vigilance under the Lin Yu community under the dispatch of Han Bing, almost achieving one post in five steps and one sentry in ten steps.

But from the afternoon to the evening, nothing unusual happened.

After the family fell asleep, Lin Yu didn't enter the bedroom, still sitting in the living room watching TV, but he didn't play a sound, and listened to the movement outside the door with both ears vigilant.

Airplanes!

At this time, in the quiet living room, his mobile phone suddenly rang suddenly.
