"Witch Department, these equipment can be equipped with at least one battalion..."

"Stop, don't touch anything inside, the technical reconnaissance team, enter the field." Wu Xiaoyun shouted coldly. Although the bomb at the door was very ordinary, and people with common sense of explosion could get it out, but who knows what secret mechanisms or traps there would be?

The technical investigation team entered the venue and quickly searched and collected footprints and fingerprints and other related information.

"The Witch Department is very clean and has almost no value." said the technical detective team leader, "From the weapons and the dust on the table, someone has been here recently. The Witch Department, what is this?"

On white gloves, some subtle black particles.

"Is it iron filings?"

"Well, it is the iron filings filed with a steel file. Look at the tools here, this should be the residual iron filings of the gun filed." Wu Xiaoyun looked carefully and said.

"The Wu Chu is really a wise eye."

"Sister Yun, have we found the fierce gun? Could this iron chip be left behind by the fierce gun? The gunman deliberately squashed the number on the gun, so that we can't find the origin of the fierce gun?"

"It's possible, can I make a component comparison?"

"The amount of iron filings is too small, but you can try it, but there is no guarantee of results." said the technical investigation team leader.

“Compare now.”

"yes!"

"Take a photo first, then count the weapons and equipment, register and file one by one, and bring them all back to the Security Command." Wu Xiaoyun ordered.

"yes!"

"Director Bidfer, it's time for us to talk."

"Director Wu, I really don't know that there are arms hidden in this basement, and you also see that the door is locked and cannot be opened..."

"The rust on the lock and the lock core is man-made. Can you tell me, who knows the existence of this key, or who can get this key at will?" Wu Xiaoyun asked.

Since the lock can be opened with a key, the person hiding the arms here must also have a key, otherwise how could he get in and out?

Also, the insiders must be insiders who can enter and exit the exhibition hall freely. There must be people related to gunmen in the exhibition hall. Pan Xiaoyu should not be. Time is not up to date, and these weapons and equipment are definitely not right. They are transported in now.

Judging from the above, no one has cleaned it for at least half a year, and Pan Xiaoyu has been working as a custodian for three months when she came to Wanguo Exhibition Hall.

"In addition to one of the keys in this basement, I have one in the storage room. Because it is piled up with debris, I have never taken it out and used it before."

"You haven't noticed that anyone has touched your drawer?"

"No."

"Confirm not."

"I took over the key from the previous director, and this key has never been moved. If Director Wu hadn't come, I wouldn't have remembered that this key was in my drawer." Bidfer explained.

"Wait, you just said that there is also a key in the storage room?"

"Yes, there is a storage room for all the room keys in the exhibition hall, and even my office is no exception." Bidfer said.

"Mengyu, go to the storage room immediately and see if the key to the iron door in this basement is still there?"

"yes."

About five or six minutes, Ding Mengyu ran back with a breath: "Witch, the key is gone."

"Ma Wu, take Pan Xiaoyu back to ask questions immediately."

"yes."

"Mengyu, inform Song Yunfeng to come back soon and we will go back to the inspection office." Wu Xiaoyun ordered.

Wu Xiaoyun returned to the inspection office and it was almost twelve o'clock. The cafeteria hurriedly ate a few bites of food. When someone came to report, Ma Wu brought Pan Xiaoyu secretly back.

Song Yunfeng also rushed back from outside.

Several main responsible persons involved in the case handler met together to further sort out the case.

"I went to see several witnesses who provided clues. They all said they had seen this young man in a suspender suit and a baseball cap, but the descriptions were somewhat different. Some said it was a young woman, some said it was a man, but they all said it was a man. The man always put his hands in his pockets and never saw him take it out."

"That's the case that this person does exist, but I didn't know where he went, right?" Wu Xiaoyun said.

"Yes, but we made a movement trajectory diagram based on the clues provided by the witnesses. Please take a look at it!" Song Yunfeng handed over a picture.

"According to the time described by the witness, this is the first time the person wearing a baseball cap appears, and then here, the time we took the photo should be at this position... The last one appears..."

“Is there a safe passage nearby?”

"Yes, you can go out from here, but we have been guarding that door. We shouldn't be able to go out from here, but it seems we can go to the second floor."

"You can go to the second floor, there is a staircase here, which seems to be right next to the public bathroom."

"No, if someone really goes to the second floor from here, our people will definitely find it. Do you think the basement is also close to it?"

"Yes, you should be able to pass here!" Everyone recalled the layout in the exhibition hall carefully and found that it was really the case.

"But we didn't find any clues in the basement?"

"How did he leave? Come and go without a trace. Isn't this awful thing?"

"There must be clues that we didn't find. I think it's still in that basement, how did so many arms be transported in?"

"This is too simple. You can create an exhibition and then carry it in, and it has no technical content."

“That’s right.”

"Have the weapons and equipment been checked?"

"After checking, they are all good products, most of them are German products, very good."

"These weapons and equipment must not be purchased through formal channels. It is not easy to find out their source, but these people actually smashed the gun numbers in one fell swoop. This shows that some people know the origin of these guns. There are many arms brokers in Wuhan, but if you want to buy German goods..."

"Look for Hans, I hope he can provide us with some clues." Wu Xiaoyun ordered decisively.

"Okay, I'll go and ask him for tea now." Song Yunfeng stood up and said.

"I brought Pan Xiaoyu back. I will interrogate Ma Wu in person later." Wu Xiaoyun called Song Yunfeng outside and whispered, "You greet him. There will be nothing wrong with me, but make sure she really has nothing to do with this matter."

"Don't worry, Mr. Hu personally made a guarantee for me." Song Yunfeng said.

"I'm relieved." Wu Xiaoyun nodded. This is not a joke. Life is a trivial matter. If it is not done properly, it will cause huge friction between the Kuomintang and the Communist Party.

"I hope Pan Xiaoyu can provide some valuable clues so that we can find the real murderer of the shooting as soon as possible." Song Yunfeng said.

"Hope."

In the inquiry room, Pan Xiaoyu looked like a frightened deer, lowering her head and showing restrained body. She had never experienced such a thing and was completely confused.

"Pan Xiaoyu, please come here, just want to know about the situation from you, don't be afraid."

"I really don't know anything. I'm just a custodian." Pan Xiaoyu explained with a pale face.

"We invited you to come because we wanted to ask you a few questions. As long as you answer it according to facts, we will let you go back to work." Wu Xiaoyun said.

"What do you want to ask?"

"You work in the Wanguo Exhibition Hall, have good friends or people who are closer to you?" Wu Xiaoyun asked in person.

"Friend, I'm in the custody room, and basically no one comes here. If you want to say something about your friend, Qiao Ya will be the one."

"Who is Qiaoya?"

"Joya is the secretary of our director. She is very nice and often talks with me in the custody room. She only talks to me in the entire exhibition hall."

"How many years have Qiao Ya worked in the exhibition hall?"

"She came early, one year."

"How did you know her?"

"I met her during the recruitment interview..."

"Did you know that the pavilion has a basement?"

"I know, when I came, Qiao Ya took me through the entire pavilion. The locks on the iron door in the basement were rusted and the keys couldn't be opened."

"Have you opened it with the key yourself?"

"No, I heard Qiao Ya say that the basement is gloomy. I have been there that time, and I have never been there again."

"So, Qiao Ya knows there is a basement key in the storage room?"

"Yes, before I came, Qiao Ya was in charge of the storage room, so of course she knew." Pan Xiaoyu replied.

"Bring Qiao Ya back now!" Wu Xiaoyun ordered Ding Mengyu.

"yes!"

"After that, did the basement keys remain in the storage room?"

"Yes."

“Has it not been lent out or lost?”

"No." Pan Xiaoyu thought for a while and shook her head.

"Joya is about the same figure as you, and she also likes to use jasmine soap, right?" Wu Xiaoyun asked.

"How do you know that Qiao Ya likes the smell of jasmine?"
