Siheyuan (courtyard house): My father, Li Yunlong!

The red dot on the detector screen almost coincided with their location, indicating that the signal source was there.

The two exchanged a glance and began to search separately.

Walls, floors, ceilings, the backs of furniture... no corner is overlooked.

The experienced Lin Taotao was particularly meticulous, gently tapping the wall with her fingers to listen for any hollow sounds.

"Here it is!"

Lin Taotao let out a soft cry.

She squatted down next to an old filing cabinet that seemed to be integrated with the wall, her fingers groping along the gap where the cabinet met the wall.

"It's loose; the back is empty."

Li Zhenhua leaned closer and indeed found that the filing cabinet seemed to be movable.

He was overjoyed and was about to push the cabinet open forcefully.

"etc!"

Lin Taotao suddenly grabbed his arm, her expression unusually serious.

She gestured for Li Zhenhua to step back, then carefully squatted down and took out a small mirror and a flashlight from her pocket, using the reflected light to observe the area below the junction of the filing cabinet and the wall, as well as the depths of the gaps.

"Look here."

Lin Taotao lowered her voice and pointed with her flashlight to a very inconspicuous thin line at the bottom of the cabinet, almost blending into the dust.

"A very thin steel wire is attached to the inside of the cabinet. If you forcefully push the cabinet open, and the force is incorrect or the direction is off, it could very likely trigger the mechanism."

Li Zhenhua looked in the direction she pointed and couldn't help but gasp, his back instantly breaking out in a cold sweat.

If Lin Taotao hadn't been so meticulous, the consequences of his rash actions would have been unimaginable.

Lin Taotao held her breath, took a small multi-tool from her keychain, and carefully inserted it into the gap, her movements as gentle as if she were defusing a bomb.

She first cut the thin steel wire that served as the trigger mechanism, and then carefully checked the cabinet door hinges and connections. Only after confirming that there were no other tricks did she signal to Li Zhenhua that it was okay.

"Alright, we should be safe now."

The two of them worked together to slowly move the heavy filing cabinet, revealing a hidden niche behind it, just the right size for an adult to curl up inside.

Inside the niche, a well-preserved old-fashioned radio and a hand-cranked generator are clearly visible!

Although it was covered in dust, the parts were intact, and there was even a small bottle of lubricant and several codebooks next to it.

"Found it!"

Li Zhenhua suppressed his excitement and said in a low voice. Lin Taotao also showed a relieved and accomplished smile.

"That's it! These guys are really good at hiding, they even set a trap, they're cunning."

Having successfully found their first radio station, the two men's confidence soared.

After carefully restoring the site to its original state, they quietly left the abandoned old building.

"What do we do now? Report it directly?"

Li Zhenhua asked.

Lin Taotao shook her head and gave a professional analysis.

"The evidence we've submitted so far isn't sufficient. We only know there's a radio station here, but who's using it? When is it being used? Who are their accomplices? Acting rashly will only alert them. My suggestion is to immediately report this secretly to Director Ma and Section Chief Sun, requesting 24-hour covert surveillance of the area, waiting for them to come to us! As soon as someone uses the radio, we'll catch them red-handed!"

Li Zhenhua wholeheartedly agreed.

"That makes sense! Let's do it that way! Let's go to the administration building first and confirm the other location."

The two took out the detector again and took a detour to the administration building.

Once inside the building, to avoid arousing suspicion, they pretended to be working normally, moving around between different floors.

Sure enough, as they approached the office of Sun Pangzi, the head of the logistics department, the red dot signal on the detector screen became exceptionally clear and strong.

Li Zhenhua's heart sank. Thinking of the logistics director who had greeted him with a beaming smile and warm hospitality on their first meeting, even personally escorting him to his dormitory, he found it hard to associate that slick, fat man with the word "enemy agent."

But the detector's indications are correct.

"The signal source... is in Director Sun's office, or somewhere right next to his office."

Lin Taotao said in a low voice, her eyes sharp.

When the lunch break bell rang, the building gradually emptied out as people headed to the cafeteria for lunch.

After confirming that no one was in the corridor, Li Zhenhua and Lin Taotao quickly opened the door to Director Sun's office and slipped inside.

The office is spacious and clean, with documents arranged in an orderly manner.

The detector led them directly to a tall bookcase against the wall.

Even without Lin Taotao's reminder, Li Zhenhua was extra careful this time. After a thorough inspection, he discovered a hidden compartment behind the bookcase.

The two worked together to carefully move aside several rows of books, revealing a hidden safe-like compartment behind them.

This hidden compartment wasn't equipped with any physical traps, but the lock was quite ingenious. However, this didn't stump Lin Taotao. She once again demonstrated her professionalism, using the tools she carried with her, and after a few minutes of focused work, the hidden compartment was opened with a soft "click."

Inside, there was another set of radio equipment that was smaller and looked more sophisticated!

Next to it were several codebooks disguised as ordinary work notebooks and several slips of paper filled with numbers.

unambiguous evidence!

Li Zhenhua and Lin Taotao exchanged a glance, both seeing the shock and solemnity in each other's eyes.

Lin Taotao carefully checked the radio and codebook, and after confirming their authenticity and danger, she gently restored the hidden compartment door to its original state.

She stood up, dusted off her hands, and looked at Li Zhenhua with sharp eyes.

"What should we do now? The evidence is conclusive. According to procedure, we should immediately take the suspect into custody and report to the higher-level public security department and the Ministry of Industry's Security Bureau."

Li Zhenhua did not answer immediately; his brows were furrowed and his mind was racing.

Lin Taotao is right, this is the standard procedure.

But this completely escalated the situation!

The head of the logistics department at Hongxing Steel Rolling Mill is an enemy agent!

This is absolutely a shocking case!

Once the news spreads, the entire leadership team of the steel rolling mill will face enormous political pressure and scrutiny.

As the top leader, Director Yang cannot escape responsibility for his poor judgment in personnel selection and lax management. Forget about promotion, it's hard to say whether he can even keep his current position.

Sun Weimin, the head of the security department, was the first to bear the blame. With such a major blunder in his subordinate department, he could not escape responsibility.

As the person directly investigating the case, although he has made meritorious contributions, he will also be caught in the eye of this huge storm, and his future situation in the factory will become extremely complicated and delicate.

More importantly, how much impact will this have on the production and stability of the steel rolling mill itself?

In a large factory with tens of thousands of employees, the atmosphere is tense and the consequences are unimaginable.

"Captain Lin."

Li Zhenhua took a deep breath and looked directly at Lin Taotao.

"Following procedures is a matter of course. But have you considered the consequences if this gets out?"

Lin Taotao raised an eyebrow.

"I'm a police officer, and my duty is to find out the truth and fight crime. As for political influence and personnel changes, those are not my priority. Of course, I understand your concerns."
