"I still need to check that, and I have to do it secretly. Auntie! Where did your group eat and drink during the experiment?"

"Nowhere, it's all in the research institute's cafeteria. However, since we don't have a specific time, the cafeteria prepares our food separately and delivers it to our lounge."

That's right. It has to be done separately. Otherwise, everyone else in the research institute is fine, so why are they the only ones who are having problems?

Who cooks for you in the cafeteria?

Nangong Xi: "Master Chen!"

Where does he live?

"All research institutes are registered."

"Walk!"

We then went to the research institute. Ge Gong, Yuan Li, and I didn't go up; only Nangong Xi went up to take a look.

After she returned, we first sent Engineer Ge and Yuan Li back, and then Nangong Xi and I went to find Master Chen.

In an old residential area, a car was parked downstairs in front of a building.

“It’s up there, 501! Master Chen is also a veteran. He worked in the city government for a few years before being transferred to our research institute.”

I nodded: "Let's go!"

We went upstairs together, and as soon as we knocked on the door, we saw Roger and a policeman inside.

"Engineer Zheng? What are you doing?"

It seems their investigation has reached this point as well.

"Can't we show some concern for our employees?"

Roger raised his hand, which was wearing a watch: "It's so late, isn't Engineer Zheng's reason a bit far-fetched?"

Damn it, I was giving him too much credit.

My heart skipped a beat, and Roger, Master Chen, and the other policeman all froze in place.

I asked Chef Chen directly, "What medicine did you add to the food for the research team?"

With a dazed look in his eyes, Master Chen mechanically said, "There's no medicine, it's all normal food."

Hmm? Looks like it's not him.

Nangong Xi, standing to the side, asked curiously, "What's wrong with him?"

"Hypnosis!"

"Oh? You can do this too?"

I nodded.

Then I asked Roger, "Who ordered you to investigate this case?"

I didn't have a chance to hypnotize someone in the interrogation room just now because someone was watching from the next room. This time, I finally got caught.

"An order from the newly appointed Chief Qi of the National Police Headquarters."

The Director General of the National Police has also been replaced?

"Then why were you so rude to me? Are you so sure there's something wrong with my information?"

"No! This is Section Chief Ma's investigative strategy: to provoke the suspect, making it easier for them to slip up."

I even showed my cow's feet!

It seems the Special Investigations Division is fine; they're focused on solving the case.

This is complicated. Who is trying to harm me?

Are they so confident that they can smear me, force me to disclose information, or prevent the authorities from using my technology?
