After hanging up the phone, Tang Ze got out of the car helplessly and walked upstairs.

Originally, he planned to let Ayako leave work early, but he didn't expect that she was in a meeting. It was obvious that there was an important matter to be resolved. Naturally, Tang Ze would not be so willful as to let her end the meeting like this.

After a tiring day of running around, Tang Ze naturally didn't want to wait in the car, so he simply got on and rested for a while.

When he thought of this, Tang Ze suddenly realized that he seemed to have forgotten to inform Hattori Heiji that the case had been solved, so he quickly took out his phone and contacted Hattori Heiji.

Fortunately, Hattori Heiji didn't know about the situation here, so he didn't care that Tang Ze took a long time to remember him, but turned around and asked about the follow-up of the case.

Because the truth of the case was found from his side and had basically been told by Kato Takanori's father, Tang Ze also briefly talked about the experience of Kuki Ritsuko and Inspector Kakuta and others meeting Kato Takanori when she was a child, and added some information.

"Anyway, thank you for your hard work this time. You've been a great help." Tang Ze said, "I'll treat you to a nice meal next time we meet."

"You're welcome. I've learned a lot from this investigation."

Hattori Heiji said: "That machine that can penetrate the ground to search for bones is really an eye-opener for me.

And the method you mentioned of extracting trace substances from Yakushiji's mobile phone to locate the other party's location even makes me feel like Sherlock Holmes relying on a bit of dirt to trace back to the source!

Even Sherlock Holmes could only identify visible soil, but you can identify things that are almost indistinguishable to the naked eye. This instantly made me feel the power of technology."

"Since you are so interested in these scientific research equipment, why don't I take you to visit the Kesouyan next time?"

Hearing Hattori Heiji's interest, Tang Ze smiled and invited him, "Although the Kansai region is also gradually expanding, many advanced machines are only promoted to other places after they have been verified in use here.

If you want to see high-tech equipment, it’s best to come visit us.”

"Really? It's settled then. It's a deal!" Hattori Heiji's brows lit up when he heard that. "I'll call you when I get there."

"Welcome." Tang Ze responded with a smile.
