This made him squint his eyes. Are these unknown substances causing death?

When he told Han Yifei his guess, the latter also frowned.

"There are four people."

Han Yifei looked at the test report and said to Xiao Chen.

"Well, let's focus on communicating more with their families."

Xiao Chen nodded.

"I'll meet the four of them alone and see if I can find out anything."

"good."

But what disappointed Xiao Chen was that he didn't find any abnormalities in these four people.

"Yifei, where are those drugs? Give me some."

Xiao Chen thought for a while and said to Han Yifei.

"Huh? What to do?"

Han Yifei was curious.

"I'll ask Su Qing to help me analyze it and see if I can find anything."

Xiao Chen lit a cigarette and said slowly.

"good."

Han Yifei nodded and asked someone to get a small packet of powdery substance.

"Do you still need me here? If not, I will leave first."

Xiao Chen looked at Han Yifei and said.

"Well, you go ahead and do your work. If anything happens, I'll call you."

Han Yifei nodded.

"good."

After Xiao Chen said a few more words to Han Yifei, he left the police station.

He thought for a while, and without further ado, went straight to the resort where Su Qing's laboratory was located.

When he got there, he called the landline number Su Qing told him.

"Hey, Xiao Chen, what's wrong?"

Su Qing answered the phone.

"Huh? How did you know it was me?"

Xiao Chen was surprised.

"Only you know this number...and it's also displayed."

Su Qing said slowly.

"All right."

Xiao Chen nodded.

"I'm at the resort and I have something to ask you about."

"Huh? Okay, I'll pick you up."

After Su Qing finished speaking, she hung up the phone.

Soon, Su Qing appeared.

"What's wrong?"

"Let's talk after we go in."

Xiao Chen shook his head and said.

"good."

A few minutes later, the two returned to the laboratory. Xiao Chen took out the packet of powder and handed it to Su Qing.

"What's this?"

Su Qing took it, looked at it, and smelled it. It was colorless and odorless.

"This is the drug I was talking about."

Xiao Chen looked at Amelia Su and briefly explained what happened just now.

After listening to Xiao Chen's words, Su Qing frowned.

"Some unknown substance?"

"Yes, they found some unknown substance in their blood. As for the tests for these drugs, the results are not yet available."

Xiao Chen nodded.

"You want me to analyze these drugs?"

Su Qing asked.

"Well, I want to know its composition, and how it can make people calm down instantly in such a painful state... No, it's not accurate to say quiet, it should be said to be peaceful! That kind of state is like...

…I can’t tell, anyway, the scene is very weird.”

Xiao Chen frowned and said.

"serene?"

Su Qing was also stunned.

"Would it have a calming effect, that's why..."

"No, the sedative effect only makes people quiet, it has nothing to do with this."

Xiao Chen shook his head.

"Well, let me analyze it."

Su Qing nodded and put the things in her hands on the test bench.

"how long will it takes?"

Xiao Chen asked.

"Three to five days."

Su Qing thought for a while and said.

"OK."

Xiao Chen nodded, he also knew that this thing was not that simple.

If it were that simple, the Longhai police would have figured it out a long time ago, and they wouldn't have been talking about it for several days without having any clue.

While Xiao Chen was chatting with Su Qing, Han Yifei also reported the latest situation to Zhang Jianming.

After Zhang Jianming heard this, he realized the seriousness of the problem and reported it to the Ministry of Public Security without delay.

In just one hour, a certain deputy minister of the Ministry of Public Security issued an order to investigate and find the source in the shortest possible time!

The deputy minister even said that if necessary, someone from above would be sent to investigate.

Han Yifei was also in Zhang Jianming's office at that time, and she also heard what the deputy minister said.

After she finished listening, she objected directly without waiting for Zhang Jianming to speak.

The deputy minister was quite angry at first, who could talk to him like this?

But when he found out it was Han Yifei, he immediately lost his temper. He couldn't afford to offend the eldest lady of the Han family!

At Han Yifei's request, she took full responsibility for this case!
