“This way, the sound signal can then be received by specialized receiving equipment.”

Lin Chuan explained in great detail.

However, such a field was indeed a blind spot for them.

All three had a look of bewilderment on their faces.

They couldn’t understand a thing!

Lin Chuan’s mouth twitched slightly, “Simply put, when the external radio electromagnetic waves come in, it starts working, and through a series of measures, it transforms into a sound signal. Then it is received by specialized receiving equipment, achieving the purpose of eavesdropping.”

The three looked as if they sort of understood, as if they roughly got the point.

He Song nodded, “I never imagined we’d be using such high-tech products.”

Lin Chuan shook his head slightly and smiled, “Captain He, this is a very old product. It’s not necessarily a ‘golden lip’ eavesdropper in the pot of the Drug Enforcement Team; it could be something else.”

“I’m all ears.”

Now, He Song was like a student in a class, humbly asking a teacher for knowledge.

Based on Lin Chuan’s scientific briefing just now, He Song felt that Lin Chuan could be invited to conduct counter-eavesdropping training for Anling Police Station in the future.

Emphasizing professionalism!

Lin Chuan laughed, “The ‘golden lip’ eavesdropper belongs to a passive eavesdropping device, mainly relying on environmental electromagnetic waves or other external energy sources to operate, without the need for an internal battery or external power supply.”

“For example, the Radio Frequency Eavesdropper, which can use cell phone signals, wifi signals to collect energy, and drive the eavesdropping device to work.”

“After disassembling the flowerpot, the technical personnel of the investigation team can then determine what type of eavesdropper it is.”

After hearing this, He Song had an epiphany.

He then cursed angrily, “These criminals have become so cunning in their methods.”

Lin Chuan chuckled.

What followed was much simpler.

The Drug Enforcement Team didn’t need to hurry to dismantle the flowerpot in order to avoid startling the snake. They only needed to confirm the source of this batch of flowerpots, determine the location of the receiving devices for these few eavesdroppers, and they could trace it back to the mastermind directly.

However, with the technical level of the Anling Police Station, determining the eavesdropper receiving device might take a long time.

“Brother Lin.”

At that moment, He Song’s face held a smile as he poured Lin Chuan another cup of tea.

Lin Chuan fully understood He Song’s intention and directly said, “Captain He, you might want to check out the Warm Flower Shop on the street outside your office wall.”

The smile on He Song’s face had yet to fade before it froze.

Had Brother Lin already suspected someone?

Shen Qianqian and Hu Daqiang were also stunned.
