Before returning to the office, Tang Ze first went to the large office of the Scientific Research Institute and placed the flowers that Samejima gave to Sato Miwako there.
This large office is where Saito Hiroshi and his colleagues usually handle clerical work or stay when they have nothing to do. There is also a conference table for them to discuss cases after analyzing evidence.
Generally speaking, if there are outsiders here, they will definitely come here. This is why Tang Ze puts the flowers here.
After all, if Samejima continues to follow up on this case, he will definitely come to Kesouyan to inquire about the situation.
And this is the place where the other party is most likely to come. Since Tang Ze promised Sato Miwako to help him refuse, it is naturally most appropriate to put him here.
After instructing people in the office not to touch anything, Tang Ze walked towards the office.
Waiting is the most torturous time, especially when the case is right in front of you and there is no progress.
He always stays calm when facing big things, and he can still remain steady while waiting for Tang Ze.
He spent the morning reading psychology books to pass the time. Just when he thought the day was over, he received a call at four o'clock in the afternoon saying that the results were out.
This result shocked Tang Ze so much that he even suspected that these young people under him had developed a rebellious mentality and were expressing their dissatisfaction in a deceptive way.
"What's going on? With so many combinations, we won't be able to finish testing them even by tomorrow, right?"
After arriving at the large office, Tang Ze looked at Saito Hiroshi standing beside him and asked, "Why are you so fast?"
"Indeed, if you combine more than ten kinds of enema and more than thirty kinds of fertilizer, the quantity is really too much."
Saito Hiroshi nodded and smiled, "My guys thought the same thing at first. When they were assigned tasks, they looked dejected, just like they were on the battlefield.
But when they were doing the experiment, I suddenly thought of something.
That is, many fertilizers on the market today are artificially synthesized and do not contain impurities.
So I asked them to exclude the fertilizer that did not contain impurities from the first test.
This eliminated most of the fertilizers, leaving only three types rich in impurities.
We have been experimenting with the remaining three fertilizers and enema combinations."
"So what's the result?" Tang Ze looked at Saito Hiroshi, but judging from his current reaction, he already had the answer in his heart.
"Unfortunately, the fertilizer you bought combined with the glycerin in the enema produced a completely different burning magazine than the one at the crime scene."
Saito Hiroshi shook his head and said, "Fertilizer is an easier source, but the criminal may have used other methods...
Well, you are a professional after all, maybe there are other ways to use nitroglycerin.
Give me some more time, I'll continue to search for information and see if there is anything that is as easy to get as fertilizer and can achieve the same effect."
"Professionals...fertilizer..." Tang Ze on the side listened to Saito Hiroshi's words thoughtfully.
Although he had known this conclusion for a long time, they had not made any breakthrough in this inference.
But he vaguely felt that this would be a breakthrough, but he didn't have any clues at the moment.
"By the way, I heard that you brought this pot of flowers? And you specifically told me not to touch it?"
Just as Tang Ze was lost in thought, Saito Hiroshi nodded at the flowers on the table and said with a smile, "What do you mean? If it's a gift from your girlfriend, it shouldn't be placed here, right?"
Tang Ze, who was lost in thought, subconsciously fixed his gaze on the flowers. Looking at the beautiful blooming fiery red flowers, a bold idea quietly emerged in his mind.
"I need a favor from you."
Tang Ze's tone was a little heavy. He looked at Saito Hiroshi seriously and slowly stated his request.
When Saito Hiroshi originally agreed, there was a relaxed look on his face, but when Tang Ze finished his request, Saito Hiroshi's pupils shrank and his expression became more solemn.
.........
That night.
It was already 8 o'clock in the evening, long past the time to get off work, and the sky had already become completely dark. Cars were passing by on the road one after another, heading home.
But in the empty scientific research institute, Tang Ze and Saito Hiroshi did not leave.
Not only that, he also called Takagi and Sato Miwako over.
"Sorry to have kept you waiting."
As everyone was waiting in the big office, Samejima Ryuhei walked over quickly and said, "I was planning to come here after get off work, but I ran into Yamamura Kage on the way.
I noticed something was wrong with him, so I followed him. I found out he had some lamp oil and seemed to be looking for someone to set on fire.
"This guy is really unrepentant!" Sato Miwako frowned and asked, "What happened next?"
"I worked with Detective Gongchang's men to subdue him when he set the fire. The fire was newly started, and we were prepared, so we put it out quickly."
Samejima Ryuhei said this while looking at everyone and said, "Then I wonder what experiment you all want me to see?
If it's the starting point of the fire, catching Yamamura Ying in the act should make him confess to something he hadn't confessed before."
There seemed to be nothing wrong with what he said, but Takagi and the other two standing by had strange expressions on their faces and kept looking at Tang Ze.
After all, what the other party meant was that Tang Ze's previous interrogation and questioning were completely unreliable, and this time he caught the other party in the act, so it naturally looked more convincing.
From a normal person's perspective, most people would think that this guy actually set the fire after being caught, so the last fire must have been set by this guy.
