Once, I wanted to be a good person

But this approach can be used later to lock down suspects, though it’s too complex to prove assumptions in the early stages.

So Fang Ze came up with a second idea: to inspect the soles of the crew members’ high heels.

The train Fang Ze was on is a magnetic levitation train, and the track retains certain magnetism even when powered off.

And many women’s high heels have iron plates on the soles to prevent wear. So... if the train from a couple of days ago was indeed a projection, then when these crew members "boarded the train" for checks over the past two days, they were actually standing on the tracks.

Under the influence of magnetism, the soles of these crew members’ high heels could also become magnetized, so it would only require testing with an iron wire.

Thus, Fang Ze went to the crew members and asked them to take off their shoes, using iron wire to test them.

Luckily, three of the six crew members had iron plates on their high heels, and as expected, they were magnetized during testing.

This proves that these crew members were indeed not on the train in the past two days, but were working on the tracks.

This also proves that the train has been a projection for the past two days.

After listening to Fang Ze’s account, before Chairperson Liu could react, Black Shark couldn’t help but clap his hands and say, "Ingenious! How come I didn’t think of this method!"

Saying this, he also commented, "So, after proving that the train over the past two days might have just been a projection, we can enlarge the surveillance footage, find the edited traces, and discover the actual time of the crime."

"After that, by viewing other area surveillance from before this timeframe, we can identify those with suspect profiles."

Fang Ze nodded, "Yes."

Saying this, he glanced around the secret platform and added, "Moreover, not only can we find suspects through surveillance, but there are likely suspects on-site too."

"Because, if this case is truly as I theorize, then after the projection disappears, a technological device must be lurking somewhere on this platform."

"This device is the greatest flaw in this plan, so someone is bound to come and destroy it."

Upon hearing Fang Ze’s words, Chairperson Liu, who wasn’t too knowledgeable about crime-solving, asked curiously, "Why not use Extraordinary Artifacts instead?"

Fang Ze replied with a smile, "Because technological devices are more covert."

"Even if Extraordinary Artifacts have limited capabilities, they theoretically leave traces of the Power of Laws fluctuations. The Security Bureau can easily figure it out in such a short time. However, technological devices are different. As long as they are small enough and concealed, they are hard to discover and easy to deal with afterward."

After Fang Ze’s words, Chairperson Liu pondered briefly and then asked, "Then... how do we find this second accomplice?"

Fang Ze replied, "Use the Lie Detection Treasure."

Chairperson Liu, hearing this, couldn’t help but say, "I’ll have someone prepare it right away."

However, Fang Ze simply raised his hand, "No need for such trouble; I happen to have a Lie Detection Treasure on hand that we can use immediately."

The Lie Detector Treasure Fang Ze held was the [Lie Rootless Vine] he had acquired in the Outer Realm. This plant’s capability is simple; whenever it detects someone lying, it converts their lies into random babble like "Ah bah ah bah."

Not long ago, when Fang Ze tested Elder Councilor Chen, he already planted it in his ear. So, he can use it directly now.

Upon hearing him have a Lie Detection Treasure at hand, Chairperson Liu became interested, curious about the next steps. So, he suggested, "Shall I gather everyone and start lie detection now?"

Originally, he thought his proposal was entirely reasonable, but Fang Ze still shook his head, "No need. First, send someone to bring the supervisor of this secret platform over; I’ll ask him first."

Upon hearing Fang Ze’s request, Chairperson Liu then realized Fang Ze already had a prime suspect. Consequently, he quickly summoned individuals from the Security Bureau to call the supervisor over.

Shortly afterward, the platform’s supervisor arrived beside them—a middle-aged man who was the first to receive reports and criticize the crew members earlier in the morning.

The middle-aged man came to Fang Ze, sweating profusely, belly sticking out, gasping for breath. He glanced at Chairperson Liu and Fang Ze, then at the surrounding Security Bureau and Special Service Department Commissioner members, greeted them politely, "Council Members, what can I do for you?"

Fang Ze scrutinized him briefly, nodding slightly. His suspicion of the supervisor stemmed from ample reason.

Firstly, he learned that this platform was managed by this supervisor, thus granting him ample opportunity to aid in this case.

Secondly, although every on-site individual could potentially destroy evidence, those who contacted the platform earlier remain more suspect as the risk diminishes significantly.

If the mole were a Security Bureau commissioner, the mole might not arrive before station staff discover the device.

Consequently, those most suspect on-site include the supervisor and the six crew members.

Having probed the six crew members earlier, none turned out to be suspects, making the supervisor Fang Ze’s primary suspect.

With this in mind, Fang Ze regained focus and asked the middle-aged man, "What is your name?"
