But Old Lady Tang definitely didn't dare to come out again to do evil during this time, so basically the suspicion of being sad about this old woman can be ruled out.

It's just that in terms of the current situation, Jiang Chen really doesn't know where to investigate.

"At least what is certain now is that this guy's death was not a suicide." Jiang Chen's eyes narrowed.

He already knew roughly what was going on, but he didn't want to talk any more nonsense anyway, he just wanted to find out where the real murderer was.

Soon, Jiang Chen went directly upstairs, that is, the office where this old Zhang fell downstairs.

When Jiang Chen passed, he found that the office was spotless, as if someone had specially cleaned it, but the traces of Lao Zhang's activities here before were still there.

"Who's usually cleaning this room?" Jiang Chen soon found Hu Weidong again to ask.

Hu Weidong also told Jiang Chen's request to his subordinates to do it, and he now has to follow Jiang Chen to investigate.

"I don't know about that, but usually we clean our own rooms, and no one will come out to help." Hu Weidong scratched his head and said.

They are just cosmetics factories, and they are not large business units, so it is naturally unlikely that they will have any too high salaries.

Jiang Chen touched his chin, if this is the case, then it is even more unlikely that this Lao Zhang committed suicide, if it is said that it is no problem to pack up his things before he dies.

But keeping the room spotless was more like a secret than a tidy up, or he didn't even think he was going to die.

Jiang Chen's brows furrowed, he kept thinking about everything that had happened before, he wanted to know what had gone wrong.

"If he invited guests to dinner, it means that he poisoned those people, but Lao Zhang also has this toxin in his body...... If he was really a murderer, how could he possibly give himself that toxin? ”

Jiang Chen's brows furrowed.

Suddenly, he remembered that Hu Weidong had told him that this Lao Zhang was still a subordinate of the deputy factory director.

"Go and call the deputy factory director!" Jiang Chen snorted coldly and said.

But he thought about it for a moment and said directly: "Forget it, let's go straight over!" ”

Jiang Chen also felt that the other party might have to run away if he dragged it any longer, if it was really this person who had a problem, Jiang Chen would be in trouble if he wanted to find this person again.

Not long after, Jiang Chen set off with Hu Weidong.

As for the matter of the factory, after Lao Zhang jumped off the building, many people at the scene were obviously calmer.

It would be more appropriate to leave it to Tang Yanran to deal with it now, not to mention that Jiang Chen also prepared medicine for them, and their hallucinations would be much better if they ate it then.

"So Mr. Jiang, do you mean that they all think they are sick because they are hallucinating?" Hu Weidong looked at Jiang Chen with some surprise and asked.

"Hmm." Jiang Chen nodded.

Hearing this, Hu Weidong also took a deep breath, he really didn't expect this kind of thing.

"I didn't expect anything so magical......" he said in surprise.

"There are more things you can't think of, and that old Zhang jumped off the building because of this thing." Jiang Chen then said.

Hu Weidong was stunned, he didn't expect Lao Zhang to be because of this thing?

"If this is really made by the deputy factory director, then he really damn it!" Hu Weidong gritted his teeth and said.

Lao Zhang is actually very good, but he has some relationship with the deputy factory director, so the two usually get very close.

Jiang Chen didn't speak, he now felt that there must be a problem with this matter, such as this kind of thing that would affect people's senses, Jiang Chen didn't think it was a problem.

"So what do we do now?" Hu Weidong hurriedly asked Jiang Chen.

"Isn't this going to him? When I found him, I naturally understood everything. Jiang Chen said indifferently.

Hu Weidong nodded, and then accelerated to the small factory with all his might.

However, when they arrived, the people in the small factory told Hu Weidong that the deputy director was no longer here.

"He didn't seem to have come back since he went out yesterday morning, and now he can't get through on the phone, so I don't know what he's doing." The front desk was also a little speechless.

The corners of Hu Weidong's mouth twitched when he heard this, and he quickly told Jiang Chen about the situation.

Jiang Chen also frowned after hearing this, and then he called Xiao Hei and asked him to track down the whereabouts of the deputy factory director through the hackers.

Their trip was for nothing, but Jiang Chen didn't give up like this, but went directly to the deputy director's office.

"This deputy factory director usually works here, right?" Jiang Chen asked the front desk.

The front desk nodded, she had brought the two of them over, but she didn't know what was going on.

Jiang Chen nodded, and then he asked the front desk to leave first.

Then he took Hu Weidong in.

"What are you looking for?" Jiang Chen glanced at Hu Weidong and asked.

Hu Weidong was stunned for a moment, and then he nodded and said, "You should know, I will pay attention to it." ”

He felt that it was nothing more than some medicine or something, or something he didn't know and just show Jiang Chen directly.

Jiang Chen also looked at the things in front of him at this time, and then he began to look for them.

More than ten minutes later, the two of them had already searched the office, but they still couldn't find anything useful.

"He's going to leave something behind, at least he's going to leave a trace." Jiang Chen frowned, he didn't believe that this guy was so careful.

Hu Weidong didn't say much, and then he went out with Jiang Chen.

Then the two went to the place where the deputy director usually rested, Jiang Chen continued to go in to look for it, and this time he really found it again.

"There's a package here, half burned." Hu Weidong gave things to Jiang Chen.

Jiang Chen glanced at it roughly, then he sniffed it again, and finally his eyes narrowed.

"Sure enough, there's something wrong with this thing." Jiang Chen sneered twice.

He knew that something was wrong with this thing, and then he also packed it up, and finally handed it to Xiao Hei.

Before leaving, Jiang Chen's heart suddenly moved.

"Follow the breath of this thing, and see if there's anything like it here." Jiang Chen's eyes narrowed.

And all of a sudden, it really made him find something incredible.

Jiang Chen followed his breath and returned to his previous office, and this time, he also found something unbelievable on the ceiling.

"So much?" Jiang Chen found a whole packet of that medicine.

Jiang Chen frowned, he couldn't believe that all this was true, so many drugs, how many people did this harm?

This hallucinogenic drug, as long as it is in a specific situation, can make people fall into a pre-set hallucination, and make people feel unwell, which is pediatric.
