The two of them rushed directly from the general sanatorium to the jungle tribe, and after not seeing each other for more than half a month, the bar did have some changes. A wanted notice was posted on the door of the bar, and as before, Ouyang Lan was arrested. The bar was far less crowded than before, and a glass door at the door had been spent, looking like it had been hit with a blunt object similar to a safety hammer.

Instead of rushing into the bar, they pretended to be passers-by and walked around the bar to see if there were people watching. Sure enough, in a tall building with the main entrance obliquely upwards at forty-five degrees, someone was standing by the window, observing something with a telescope, and after seeing Chen Ziqiang's sight, he immediately shrank back, sneaky.

Under a tree half a meter away from the back door, there was an old man who set up a stall selling some trinkets, but he swept his gaze to the back door of the bar from time to time, and as long as there was a little wind and grass, he looked there vigilantly, and knew that he was watching when he looked closely.

Feng Jun said angrily: "Big brother is right, the bar has already been monitored, and they are waiting for big brother to throw himself into the net." ”

Chen Ziqiang was relatively calm, he patted Feng Jun on the shoulder and walked towards the door of the bar, "Let's go first and have a look, and then ask Xiaojun about the situation." ”

The two security personnel almost shouted out in surprise when they saw that it was Chen Ziqiang and Feng Jun, but Chen Ziqiang stopped them in time and said in a low voice: "Shh~ Conduct a security check." ”

The two security officers understood, took the detector to screen them, and then let them go. When Chen Ziqiang and Feng Jun walked into the bar, one of the security guards also walked in.

"Brother Qiang, Brother Jun, you are back, what about Brother Dong, why didn't you come back with you?" The security personnel seemed to have finally looked forward to their arrival, and kept thinking about it.

Feng Jun glanced around and asked, "What about Xiaojun?"

The security officer hurriedly pointed to the second floor and replied, "He is in the office on the second floor." ”

Xiaojun is the captain of the bar security team, and when the three of them left, he was specially asked to handle some affairs in the bar on his behalf. When they came to the second floor, the office door of the security room was closed, Feng Jun stepped forward and knocked on the door, got the consent of the inside, and opened the door to enter.

Xiaojun was checking the video at the computer desk, and when he saw their boss coming, he hurriedly got up to greet him: "Brother Qiang, Brother Jun, why are you back?"

"Brother Dong is still dealing with some things outside, but the people are already under the river, what are you looking at?" Feng Jun said as he walked over and saw that there were a lot of video files on Xiaojun's computer.

Xiaojun replied with a smile: "Brother Jun, I have copied all the videos in the monitoring room for nearly a week, and I am checking things." ”

Feng Jun immediately sensed something strange and turned around and asked, "What's going on?"

"Well, I was doing a careful patrol around the bar this morning and noticed some strange footprints at the back door, it looks like it's been a bit of a while, I'm weird, it's not usually people going to that place, so I wanted to see if there was anything on camera. Xiao Jun recalled the situation he had discovered during his patrol in the morning, his brow furrowed slightly, and an ominous illusion floated on his face.

Feng Jun analyzed and said: "You mean, someone goes to the back door of the bar? it is impossible for customers to go there, only our internal personnel, in this case, have you ever asked your internal personnel?"

"I've asked, but no one has been there, so I suspect it's an outsider, and the insiders are fine, but if it's really an outsider, I'm afraid someone is not good for us. ”

"What do you mean?" Chen Ziqiang then asked rhetorically, he felt that Xiaojun had something they didn't know.

Xiao Jun returned to his computer and replied while operating the mouse: "Not long after you left, the police from the city bureau came to Dong Ge many times, saying that he was suspected of intentional homicide, and said that there was evidence, I still know Dong Ge's character, I believe that he was blamed by someone, so I am afraid that someone will be unfavorable to Dong Ge." Look at this video, these people are the people who came to us from the city bureau to find Dongge. ”

Chen Ziqiang found that there was a familiar figure in the police team of the city bureau in the video, which was Yang Ziming, who had been on a mission with their sister-in-law Ouyang.

Yang Ziming is the captain of the criminal police team, and it can be said that the city bureau is in charge of the criminal police investigation, and his presence at the scene shows that the city bureau attaches great importance to this matter and has certain evidence.

But it is impossible for the eldest brother to be suspected of intentional homicide, where did their so-called evidence come from? Chen Ziqiang and Feng Jun fell into contemplation at the same time, this matter is too strange, it seems that there is a huge black net, trying to trap their eldest brother Qi Dongsi in it, this must be a conspiracy. Like Xiaojun, they believe that Qi Dongsi is blamed.

The few of them stayed here and looked at the next videos together, hoping to find some useful information from them, but they didn't see any suspicious person pass through the back door of the bar, let alone determine who left the footprints.

"Let's go to the back door and have a look. Feng Jun suggested.

Xiao Jun took Chen Ziqiang and Feng Jun to the back door, Xiao Jun remembered that place, he had made a mark, but this time he came to the mark and found that the footprints were gone!

"This ...... How is this possible? I saw it in the morning, and I left a mark. Xiao Jun looked at the surroundings of his mark in bewilderment, and there were indeed no footprints from before.

Chen Ziqiang and Feng Jun also felt incredible, of course they believed Xiaojun's words, but there were no footprints in half a day, so someone must have erased them, but after looking at the surveillance before, they didn't find anyone who appeared here, what the hell is going on?

This strange phenomenon, they reported to Qi Dongsi after they went back, and Qi Dongsi's expression was as surprised as they were, but he quickly fell into his own rational analysis.

Leaving footprints means that someone must have been, and the footprints suddenly disappeared mysteriously, but no one was seen deliberately erasing these footprints, did the footprints really disappear by themselves?

"This phenomenon is easy to explain. Suddenly, Ouyang Lan's voice came from behind them.

Ouyang Lan walked over to the three of them with a smile, looking much more energetic than before, she saw the puzzled and expectant gazes of Qi Dongsi and the others, and continued: "Have you ever seen the font that disappears automatically? This is a technique that we often use in the process of criminal investigation. Generally speaking, a pen can leave traces on the paper because these handwriting contains chromogens, the more concentrated the chromogenic substance, the more stable its chemical properties, and the handwriting will be very clear, and if the chromogen is chemically unstable, it will slowly decompose and eventually disappear into the air when exposed to high temperature or water. ”

Qi Dongsi suddenly realized: "You mean, this footprint is equivalent to a disappearing font, and the suspect used this unstable chromogenic substance to smear on the sole of his shoe, so that the footprints formed in this way will eventually disappear, right?" ”

"Clever. ”

"So as long as we keep looking at the surveillance video, we'll be able to find the suspect. ”

At this time, Qi Dongsi remembered something in his mind, when he first came to Jiangxia, a person had asked him to look for some special colors in the market, and at the same time, a sentence that seemed very interesting now sounded in his ears: "Anything that is unstable will eventually disappear, including love, friendship, and even family affection." ”

"No need to look for it, I already know who left the footprints. Qi Dongsi said confidently.

The three of them gathered around and asked in unison, "Who is it?"

"Old man. ”

"Old man, is that old man with a strange temper who often meets you secretly?" Feng Jun didn't have a very good impression of that old man, and even looked down on him a little, because this old man often called Qi Dongsi.

"Yes. ”

Ouyang Lan suddenly remembered the inference he had made before, this old man was likely to have a certain relationship with the Ningzhou carrion case, and he was the key figure in it, so he said: "Didn't you say that you could introduce me to meet that old man when you were in Honggang before?"

"Well, I said, in this case, I'll contact him in the next few days to see if I can arrange for you to meet. ”

Qi Dongsi originally planned to wait until Ouyang Lan's turmoil passed before arranging a meeting, but looking at it now, it seemed that the old man was already in Ouyang Lan's turmoil, so he decided to arrange it as soon as possible, as if it was to explore the wind in advance.

"By the way, Xiaolan, we've found out where your dad is. ”

"Where?" Ouyang Lan was wanted because she cut off all communications, in order not to implicate her family, she had not contacted her family, so she didn't know where her father was, she desperately wanted to know the location.

"General sanatorium. ”

Ouyang Lan's heart trembled when he heard the name of this place, generally only very serious cases will be sent to the general sanatorium for treatment, where there is the most advanced medical team, Ouyang Lan can't help but worry about his father's physical condition.

"I ...... When can I go there?" Ouyang Lan knew that if he wanted to see his father, he might have to trouble Qi Dongsi and them again, and he was a little embarrassed to talk about it all of a sudden.

However, Qi Dongsi was very good at taking care of Ouyang Lan's emotions, and he said very easily: "You can go whenever you want." ”

"Really, is it safe outside?" Ouyang Lan confirmed to Qi Dongsi.

Qi Dongsi confidently promised: "Whether it's safe outside or not, I will guarantee that you are safe." ”

Ouyang Lan trusted Qi Dongsi 100%, of course she hoped to see her family sooner, "Then let's go tonight." ”

Qi Dongsi didn't want to disappoint Ouyang Lan, so he immediately agreed, as for how to send her over, he needed to personally investigate and understand the entry process of the general nursing home, which Chen Ziqiang did not pay attention to.
