Zheng Haishan stared at the shoe repairman for a while and asked, "If you're not repairing shoes, is there any other rhythm you were using?"
"No, it's always been like this, what's wrong!"
"Nothing?" Zheng Haishan said as he walked out of the shoe repair shop, stood in front of the supply and marketing cooperative building, put his hands on his hips and looked around.
I want to find that knocking sound from earlier.
But apart from the shoe repairman's hammering sounds, there was nothing else around. What was the other party's intention in trying to get their attention?
Normally, people would secretly send out codes, afraid of being seen. But these guys did it differently, sending out codes with the sound of hammering metal.
It's more like a provocation.
The man named Zhang Bo walked up to Zheng Haishan and said, "Based on the radio waves and the voice just now, I can confirm that it was a telegram."
"Where's the launch source?" Zheng Haishan said angrily.
Zhang Bo raised his head, and Zheng Haishan followed suit.
Seeing what appeared to be a signal pole on the supply and marketing cooperative building, Zheng Haishan picked up his walkie-talkie and asked, "Has the support arrived yet?"
A voice came through the walkie-talkie: "Right away."
"Xiao Li, Xiao Zhang, come up with me. Zhang Bo, you stay down here and keep an eye on the equipment," Zheng Haishan said, keeping a close eye on it.
He then led the group to the top floor.
Apart from the signal pole, there is no other equipment on the top floor.
A young man named Xiao Zhang climbed the signal pole, pried open the data box with a screwdriver, and found the repeater inside.
When disassembling the repeater, two signal devices were found.
It's about the size of a matchbox and is connected to a feeder cable.
"Team Leader Zheng, we've found something!" Xiao Zhang shouted.
The three of them began tracing the feeder line to its source, crossing the rooftop and passing through the drainpipe. Further down, they would have to dismantle the drainpipe.
This required working at heights. Zheng Haishan used a walkie-talkie to notify the people below to send ropes. With the support of the workers, there were also many people available.
Then bring the ropes up with you.
After securing the ropes, the guards began dismantling the drainage pipes. They moved swiftly, essentially using brute force to remove them.
The supply and marketing building was four stories high. They found the feeder cable and went through a window on the fourth floor. They ran from the roof to the fourth floor and found a suspicious room. Instead of asking anyone to open the door, they kicked it open.
Upon entering, I saw a jumble of random things, all miscellaneous items.
Zheng Haishan said to the people around him, "Find me a manager or a director. Just find someone who is an official."
A short while later, Lao Lu, the manager of the supply and marketing cooperative, came over.
"What are you doing? Who are you? Let me tell you, I've already sent someone to the police station to report this. Vandalism and looting are illegal!"
Zheng Haishan stepped forward and said, "It's a misunderstanding. Because the case was urgent, we took some measures. Come, let me ask you something."
"Don't ask me who you are yet."
Zheng Haishan took out his ID from his pocket and showed it to Lao Lu, saying, "We are from the Special Investigations Unit. If you don't cooperate honestly, you may be implicated. When it comes to special investigations, it's no use trying to find a place or anything else. We are directly under your command."
This isn't meant to scare anyone. The launch site is currently located at the supply and marketing cooperative, and the origin of the launch is also there. So, this manager must have some connections. Even if he knows nothing, he can't escape blame for mismanagement.
"I don't know if you're telling the truth or not. Let's wait for the police to arrive."
"Once you're here, that's it. There's a feeder cable running from outside into this room. Who usually manages this room?"
"I don't know what line you're talking about. This room is a storage room, with all sorts of random things stored here. Nobody comes here usually."
Zheng Haishan continued, "Who has the key to this room?"
"There's no one in charge of managing it. It's just hanging on the office wall. If you have old or unused office supplies or clutter to put away, you just bring a key to open it."
"Captain, radio station found."
Zheng Haishan was overjoyed and turned to Xiao Zhang and Xiao Li, who were searching inside, saying, "Seal off the scene and take pictures."
After saying that, he turned to the supply and marketing cooperative manager and asked, "Can you explain to me where this radio came from and why it ended up in your company's storeroom?"
"I...I don't know!" At this moment, Lao Lu also saw the green radio and immediately panicked.
A voice came through Zheng Haishan's walkie-talkie: "Team Leader Zheng, two local police officers have come downstairs. They said the manager reported a case and they want to come up and take a look."
"Please come up!"
The local police officer came because the employees of the supply and marketing cooperative had reported a case, so he had no choice but to come. After checking his identification, he knew he couldn't do anything about it.
They were even temporarily requisitioned. Not only the two of them, but several staff members on duty at the station also came to help.
Discovering a radio station within the jurisdiction is no small matter.
Finally, people from the Municipal Bureau also came, bringing with them a team of on-site survey technicians.
Scan for fingerprints and other traces.
I worked until night but didn't find anything of any use.
It's worth mentioning that this is the source of the signal transmission. Not only was a radio found in the storage room, but also a laptop and a large power generator.
These things have all been modified and are buried under miscellaneous items. What can you tell from their appearance?
Or you can flip it out when you need to use it.
"The computer and power supply transmit signals through lines to the signal pole above, which then transmits or receives signals via repeaters."
Zheng Haishan glanced at the notebook, then handed it to Lei Jun, saying, "Can you use your skills to find any valuable clues in here?"
Lei Jun nodded and said, "I'll give it a try. If it's too complicated, I'll have to talk to President Xiao."
"Where is Xiaotian?"
Lei Jun nodded and said, "That's right."
"Alright, it's getting late, let's head out."
