Chen Nan did not answer Jiang Lili's question directly, because at that moment, he was carefully analyzing the surveillance footage.
He could clearly make out the young worker's features, and he could also see the powder-like substance he had scattered into the soup pot.
The Eye of AI had already been activated. With his improved strength, these eyes could now distinguish far more things.
Through his visual system, AI's analysis had basically confirmed that the powder was poppy husk powder.
It seemed everything had finally come to light, but he still needed to find that young worker. With that person's testimony, everything would fall into place.
The only difficulty now was how to find him.
Throughout the Qingyang Kingdom, every citizen's identity information was entered into the Patrol Bureau system. Citizens needed identification for travel, lodging, and everything else. Under this one-person, one-ID system, once someone was identified as a criminal, it was nearly impossible for them to flee.
Because they could not even use the most basic means of transportation.
Naturally, there were also some vagrants within the Qingyang Kingdom whose identity information could not be recorded. After all, society might have considered them barely human, so they had no need for identity information.
Chen Nan estimated that this young worker could not possibly be someone without identity information. To find him, they only needed to search through the nation's identity records. In fact, they could narrow the scope down: first search Wu City, then search the identity information of citizens in Hualong Prefecture, where Wu City was located. That should be enough to find him.
To confirm this, Chen Nan asked Jiang Lili, "What was that person's accent like? Local or from elsewhere?"
Jiang Lili thought for a moment before saying, "He was definitely from our Hualong Prefecture.
