"Mr. Feng, I'm in." After knocking on the door, Zhong Bo opened the door and entered the room. After listening to the reports of the two guards just now, Zhong Bo came directly to Qiao Feng without much delay, and the seriousness of this matter had reached the point where Zhong Bo had to report to Qiao Feng immediately.

"Ah, Uncle Zhong, just now I asked Xu Yuan to ask you, aren't you ready for the meal or something? What's the matter? Qiao Feng saw Uncle Zhong with a solemn face and asked.

"Mr. Feng, I heard something just now, and I think it's more serious, and it is necessary to tell you about the situation that the guards found during their patrol last night." Zhong Bo said with some seriousness.

"Guards? Tell me, what the hell is going on. Uncle Zhong rarely reported a problem to himself so seriously, so Qiao Feng also understood the seriousness of the problem, and asked seriously at the moment.

"When two guards made their rounds last night, they found that the door to your study was not locked." Zhong Bo said.

"The door to the study is not locked? Was it because you forgot to lock it last night? Qiao Feng didn't care too much and asked, because the work of locking the door was usually done by Zhong Bolai.

"No, I confirmed last night that the door to the study was indeed locked, it was about half past eleven, and the guard found the door unlocked around half past twelve." Zhong Bo shook his head and said, this incident was definitely not caused by his negligence.

"You mean that during this hour, someone opened the door to the study while everyone was not looking?" Qiao Feng asked.

"Probably this is the case, there are only three sets of keys to the main building, one is with you, one is with me, and the other is at the main building supervisor's place, and the main building supervisor has just handed it to me this morning, and there are no other keys other than that." Zhong Bo nodded and said.

"Could it be that someone from outside came in? What did the guard group say? Qiao Feng seemed to realize the key to this matter, it seemed that someone should want to enter his study to find something, so it was a bit serious, who it was, what was the purpose, and what he got was very critical. Qiao Feng also knew that there was a lot of very important information in his study, and once someone else got it, it would be very troublesome.

"The security team just told me that there were no alarms or anomalies last night, and I have asked them to check if the alarm system is broken, and there is no report yet, and I don't think it is very likely that someone from the outside will come in." Zhong Bo reported.

"You mean the people on the inside? It's unlikely, right? Zhang Ziyu: I've been sending someone to keep an eye on me, and I haven't reported anything wrong, and Zhang Ziyu shouldn't be able to get the key, right? What about door locks? Was it forcibly opened? Qiao Feng thought of this, but immediately vetoed it again, the people inside the Feng Mansion had basically been tested by Qiao Feng, and for so many years, Qiao Feng also trusted that these people working in the Feng Mansion would never do such a thing. So the first thing Qiao Feng thought of was Zhang Ziyu, because Zhang Ziyu felt that he had such a motive, and Zhang Ziyu also had such an ability.

"It shouldn't be, the guard said that when he checked last night, he habitually twisted the doorknob and found that the door could be opened, and there was nothing wrong with the door lock, although the room was not checked inside, but a flashlight was used to check at the door, and there was no problem." Zhong Bo said.

"That's strange, if it's not Zhang Ziyu, and it's not someone from the outside, then who else will there be? I don't know how long it has been since such a problem has occurred in the Feng Mansion. Qiao Feng fell into deep thought, and the analysis of many aspects made Qiao Feng unable to think of a reason, he would not take the initiative to suspect these housekeepers and maids in the Feng Mansion.

"I'm going to take a look at the surveillance footage, the camera that was temporarily installed last time should still record it." Zhong Bo suddenly remembered the matter of the monitor and said.

"Well, then you go and see if there is a record, I think it should be an accident or something, and I'll go to the study to see if there's anything missing." Qiao Feng said that he was also a little restless, and planned to go to the study to actually take a look.

"Well, I'll go now, I'll let Du Lei come over by the way, he may have any help with this problem." Zhong Bo nodded and walked out quickly, at present, this matter has been put in the most important position, that is, the summit that will be held in a while has been ranked behind this matter.

Soon Qiao Feng came to the door of the study, first carefully examined the door lock, there was nothing abnormal, there was no damage, there were no scratches, it seemed that there was no trace of being forcibly opened, and when he looked up, there was a small monitor diagonally above the door, which should have been installed before, but I don't know if the road can still work normally now. Opening the door, Qiao Feng did not walk in in a hurry, but stood at the door and scanned the situation in the entire study, observing the ground and the position of the furniture. After confirming that there was nothing abnormal, Qiao Feng walked into the study and came to his desk.

The position of the various things on the table does not seem to have been moved, the safe has not been moved, and there is no trace of being opened, although there is nothing important in the bookcase behind him, Qiao Feng also opened it just in case to take a look, everything is fine, and there is no change since he left last night in his memory, and there is no sign that someone has been here. Qiao Feng sat on the chair and opened the drawer of the desk one by one, there were a large number of documents in it, and there was no way to find which file was missing for a while, but there was no trace of turning, these documents were more miscellaneous, even Qiao Feng himself couldn't remember what the specific contents of these documents were, if you had to find them, you also needed to take them out and find them one by one, yesterday the guard came at half past twelve, and if there was no one in the room at that time, then it means that the person had only been in this room for half an hour. It shouldn't be too late to look for the documents in them one by one.

After the last moment, Qiao Feng used the key to open the long drawer under the desk, and the contents of this one were second only to the contents of the safe. After opening the drawer, Qiao Feng counted it, two notebooks, a USB flash drive, an audio tape, and a kraft envelope, none of these things were missing, and Qiao Feng simply flipped through the stack of documents, and the contract with the organizing committee was not lost, so he was very cautious, Qiao Feng even checked the envelope of the kraft envelope, which was still tightly sealed and not opened.

With a sigh of relief, Qiao Feng leaned back in the chair after finishing his work, and found nothing suspicious after his initial inspection, could it be that he was thinking too much? Or is it really just an accident, maybe it was really Uncle Zhong who forgot to lock it, or the guard looked at the wrong room when he came to check or some other reason, think about it carefully, there shouldn't be so many coincidences, it just so happened that the guard system was broken, the door happened to be unlocked, and that person happened to avoid the guard's inspection and those cameras outside the Feng Mansion.

Qiao Feng relocked the drawer, and was about to put the key back in the previous box when his eyes were suddenly attracted by a strange thing on the table, which should not belong to this room. It's a hair, very long hair, just next to the box with the key on the office desktop, this hair is very long, at first glance it is a woman's hair, this room is generally cleaned once in a while, it has been some time since the last cleaning, this hair can't appear on the desktop, at least not yesterday, and there are no women who have entered here recently, that is, Xu Yuan and the previous head of the main building, but the previous head of the main building is short hair, and the length of this hair is obviously much longer than her hair, Then only Xu Yuan is left, but yesterday Xu Yuan should have just stood in front of the desk and talked to herself, and it was impossible for her hair to fall on the desk.

Qiao Feng gently picked up the hair with his hand and looked at it carefully, this hair was so weird, Qiao Feng couldn't imagine any reason to explain the origin of this hair.

Could it be that someone really entered here last night? Or a woman? I put my hair under my nose and sniffed it gently, there was a floral smell, although it was very light, but I could still smell it, it should be the smell of shampoo, and the smell of shampoo could be recognized on my hair, indicating that the hair had been here for a short time.

Knock knock, there was a quick knock on the door, it was Uncle Zhong, Uncle Zhong walked into the study with a gloomy face, it is rare to see Uncle Zhong with such an expression, obviously there should be something going on.

"Mr. Feng, I just investigated the monitor, although it is not a night vision monitor, but it was recorded, someone did enter the study last night, and when those guards checked, the person was still inside and did not leave, it was after a while after the guards checked, and judging from the picture, it should be a woman." Uncle Zhong said with a bad face.

"I've found the proof, you see." Qiao Feng smiled, pointed to the hair on the table and said.

"Mr. Feng, it seems that someone really sneaked here, or a woman, what should I do?" Uncle Zhong said a little anxiously, there is a lot of important information in Qiao Feng's study.

"Since the guards were still in the room when they came, then there was only one room to hide behind this desk?" Qiao Feng said carefully and analyzed, then his eyes suddenly turned to the only place behind the desk where people could be hidden, lowered his head and looked carefully, and found that there were indeed a few long hairs on the stall that had not been found before, and after picking them up one by one, he found that they were about the same length as the hair he had just found on the desk, and they also had a faint fragrance, which further proved Qiao Feng's speculation.

"Mr. Feng, this" Uncle Zhong walked in and said in surprise when he saw Qiao Feng holding those hairs in his hands.

"It should be that guy's, I've just checked it, and nothing is missing, which means that someone should have taken it down with a camera and didn't take it away, which is a little unusual, female, it's difficult to pass the guard on the periphery of the Feng Mansion, and the hair fell down, indicating that it's definitely not a professional spy like a person, so it's very simple, although I don't want to admit it, but it should be someone inside." Qiao Feng said with a weird smile on his face.
