Before returning to the office, Tang Ze went to Kesouyan's big office first, and put the flowers that Samejima gave to Miwako Sato here.

This big office is where Saito Hiroshi and the others usually stay when they are dealing with paperwork or when they are free, and there is also a conference table for them to discuss the case after analyzing the evidence.

Generally, if there are outsiders around, they will definitely come here, which is why Tang Ze put 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 where the other party is most likely to come. Since Tang Ze promised Miwako Sato to help him refuse, it is naturally most appropriate to put it here.

After telling people in the office not to touch them casually, Tang Ze walked towards the office.

Waiting is the most tormenting time, especially when the case is in front of you and there is no progress.

Whenever there is a calmness in major events, waiting for Tang Ze is still stable.

In the morning, he read psychology books to pass the time, just when he thought the day would end like this, but at four o'clock in the afternoon, he received a call saying that the results had come out.

This result stunned Tang Ze, and he even wondered if the group of young people under him had developed a rebellious mentality and expressed their dissatisfaction in a foolish way.

"What's the situation, there are so many combinations, you can't finish testing even by tomorrow?"

After arriving at the big office, Tang Ze looked at Hiroshi Saito and asked, "Why is it so fast?"

"Indeed, if there are more than ten types of enemas and more than thirty types of fertilizers to be combined, the quantity is really too much."

Hiroshi Saito nodded and said with a smile: "The boys under him also thought so at the beginning, and they also looked dejected when assigning tasks, just like on the battlefield.

But when I was experimenting with them, something suddenly occurred to me.

That is, many fertilizers on the market are artificially synthesized and do not contain impurities.

So I asked them to exclude the fertilizer without impurities in the first experiment.

And this immediately eliminated most of the fertilizers, only three kinds of fertilizers were rich in impurities.

And our previous time was the combination of the remaining three fertilizers and enemas in the experiment. "

"So what's the result?" Tang Ze cast his eyes on Saito Hiroshi, but judging from his current reaction, he actually already has the answer in his heart.

"Unfortunately, after the fertilizer you bought is combined with the glycerin in the enema, the magazine burned out is completely different from the one at the scene of the crime."

Hiroshi Saito shook his head and said, "Fertilizer is a relatively easy way to get it, but the prisoner may have used other methods...

Well, after all, I am a professional, and there may be other ways to treat nitroglycerin.

Give me some more time, and I will continue to search for information to see what is as easy to obtain as fertilizer and can achieve the same effect. "

"Professionals...fertilizer..." Tang Ze thoughtfully listened to Saito Hiroshi's words.

Although he has known this conclusion for a long time, they have not made any breakthroughs in this inference.

But he vaguely felt that this would be a breakthrough, but he didn't have any introductions right now.

"By the way, I heard that you brought this potted flower? Why did you specifically tell me not to move it?"

While Tang Ze was in deep thought, Hiroshi Saito clicked on the flowers on the table and said with a smile, "What do you mean, if it was a gift from your girlfriend, it shouldn't be here, right?"

Tang Ze, who was in deep thought, subconsciously set his eyes on the flowers. Looking at the delicate and blooming fiery red flowers, a bold idea quietly emerged in his mind.

"I need your help."

Tang Ze's tone was a bit heavy, he looked at Hiroshi Saito seriously and said his request slowly.

When Saito Hiroshi originally agreed, his face was still relaxed, but after Tang Ze finished his request, Saito Hiroshi's pupils shrank and his face became more serious.

.........

That night.

It's already 8 o'clock in the evening, it's long past the time to get off work, the sky is already dark, and the cars on the road are also heading home one after another.

But in the empty scientific research, Tang Ze and Saito Hiroshi did not leave.

Not only that, he also called Takagi and Miwako Sato over.

"Sorry for keeping everyone waiting."

While everyone was waiting in the big office, Samejima Ryuhei walked over quickly, "I planned to come here after get off work, but I ran into Yamamura Kage on the way.

At that time, I saw that he looked a little strange, so I followed him, and then found that he was carrying lamp oil and seemed to be looking for a target for arson. "

"This guy really doesn't repent!" Miwako Sato frowned and said, "What happened after that?"

"I worked together with the bow chief criminal's subordinates to subdue him when he set the fire. The fire was ignited just now, and we were prepared, so it was quickly extinguished."

Samejima Ryuhei looked at everyone and said, "Then what is the experiment that everyone wants to show me?

If it was the source of the fire, the arrest of Yamamura Kage this time should allow him to recruit things that he hadn't recruited before. "

There seemed to be nothing wrong with what they said, but the three of Takagi on the side had strange expressions and looked at Tang Ze frequently.

After all, what the other party meant was to say that Tang Ze's previous interrogation and questioning were completely unreliable, but this time he caught the other party's current action, which naturally seemed more convincing.

From the point of view of normal people, most people would think that this guy actually set fire to it after being caught, so it must be this guy who set it off when the fire failed last time.

It's just that he didn't catch him last time, but this time he caught him, the other party will definitely not be able to deny it.

This is the inertia that most people will have, but saying it now is undoubtedly a bit of a slap in the face of Tang Ze.

"Yamamura Ying's setting fire this time can be said to be unexpected, but it is also reasonable."

Facing Samejima Ryuhei's words, Tang Ze didn't feel the slightest wave, instead he smiled and said: "But the last fire, we can't be so one-sided and think that the other party did it.

We all pay attention to evidence in our searches, and we will not attribute other crimes to the other party just because of one person's evil deeds.

Coincidentally, our discovery this time is also related to the previous case, Mr. Samejima, how about watching the experiment first? "

"Okay." Samejima Ryuhei could only nod upon hearing this.

"It shouldn't be too late, let's start." Tang Ze smiled and walked towards the laboratory, followed by everyone.

After arriving at the laboratory, Tang Ze asked everyone to stand at the door, while he and Hiroshi Saito got busy on the test bench.

"Actually, I called everyone over this time to show you a simple chemical experiment, which is also the real cause of the fire."

Tang Ze mentioned that the white-gloved right hand picked up a round container, which contained white granular substances: "This is fertilizer."

"This is a common enema on the market."

Saito Hiroshi picked up an egg-shaped pink plastic bottle, and opened the **** of the long tube above: "Now we pour these two things into ordinary gelatin capsules."

The so-called gelatin capsule is a transparent medicinal capsule, generally consisting of a cap and a body.

And this is not only used for medicine, some chemical experiments can also use this thing, for example, it is now used to hold liquid enemas and solid fertilizers.

After the two put the stuff in the capsule, they taped it together.

"If this is the case, nothing will happen." Tang Ze showed the two capsules he put in the container to everyone.

"Next, we mixed the two together."

Saito Hiroshi said as he took out a long needle, pierced through two tightly packed gelatin capsules, and placed them on the wooden chopping board in front of him.

The capsule containing the solid fertilizer was naturally unresponsive after being punctured, but the capsule containing the enema was punctured because the closed capsule was punctured, and the liquid in it began to flow.

Soon enough, the enema trickled out, and some began to enter the capsule containing the fertilizer through the hole Hiroshi Saito had pierced.

When the enema and the fertilizer are mixed together, the inside of the transparent capsule immediately starts to turn black, and the entire transparent capsule is dyed black in an instant.

Immediately afterwards, a puff of white smoke rose slowly from the capsule.

Everyone stared at the scene in front of them, refusing to move their eyes away.

People like Miwako Sato and Takagi who didn't understand the chemical reaction, looked at the changes on the tray with unstoppable surprise on their faces.

When the smoke filled the air, a little fire began to flicker in the black-dyed capsule, and it became bigger and bigger with the rapid flicker.

"Bear!"

At the next moment, a huge flame erupted from the small capsule, and the flame even directly surpassed Tang Ze.

A huge flame like a fire snake is burning fiercely, and it has been maintaining a ferocious flame without any sign of weakening.

It's hard to imagine that the chemical reaction between the fertilizer, which is slightly larger than soybeans, is just contaminated with some enemas, and the chemical reaction between the two directly produces such a large firepower.

Everyone watched the flame continue to burn, and finally gradually became smaller, and then they were relieved.

The wooden chopping board was originally covered with a layer of paint and thin planks, but the fierce firepower even burned through the layer of planks on the wooden table, and did not stop until the solid wood below.

This kind of firepower is the reaction of a soybean-sized fertilizer grain combined with an enema.

If this gelatin capsule is filled, it only needs to be combined with a little enema as it is now, and it can be used as a stealthy and fierce fire starter!

Not only that, but such a small fire starter can easily be "destroyed" by a huge flame. After all, there is not much flammable substance in these two gelatin capsules.

It's just an experiment now, and the capsules can be burned up with a relatively small dosage, let alone a larger dosage.

"Mr. Samejima, you look at the burn marks on a wooden board, are they similar to the burn marks at the scene of the fire?"

But facing Tang Ze's words, Samejima Ryuhei just stepped forward to look, but did not speak.

Seeing this, Tang Ze didn't continue to ask questions, but pointed to the tray and explained to the two Takagi who looked at the side with a questioning expression: "Enemas and fertilizers are both harmless medicines.

But there is 50% glycerin in the enema, and some kind of acidic substance in the fertilizer.

When that acid reacts with glycerin, nitroglycerin is produced. "

"It's actually two things that can be bought so easily?" Miwako Sato said in surprise.

"Although it is simple, it is not at all easy to make a fire device if you can think of the combination of the two to produce a chemical reaction." Tang Ze explained with a smile.

"However, the prisoner may not have used this method." Ryuhei Samejima, who was silent at the side, stared at the table, and suddenly said.

"In this regard, we used the exhaustive method to combine a large number of enemas and fertilizers on the market, and compared them with the combustion residues at the crime scene."

Saito Hiroshi nodded and said: "But unfortunately our data is not consistent with the chemical substances left at the fire scene."

"Unfortunately, if we can find suitable fertilizers, we can lock up prisoners through channels." Miwako Sato said regretfully.

"No, we have already found it." Tang Ze said, "We found exactly the same material."

Under everyone's amazed eyes, Tang Ze placed a pot of red flowers on the table from under the table.

"This is..." Miwako Sato looked surprised when she saw the potted flower.

"Eh? Sato-san, do you know this potted flower?" Takagi asked curiously when he saw the surprise on Miwako Sato's face.

Hearing Takagi's words, Miwako Sato had a complex expression on her face, and said with some hesitation, "This potted flower...is given to me by Samejima during dinner that day."

"Eh? Eh!?"

Because Takagi was already drunk at the time, he didn't know about it. After hearing Miwako Sato's words, he looked at Hana and then at Ryuhei Samejima, with a complex expression on his face.

I regard you as a friend, but you are peeping at my girlfriend with thick eyebrows and big eyes! ?

Takagi's face was ugly. He had a good impression of Samejima Ryuhei at first. As a firefighter, he is not afraid of life and death to save people~lightnovelpub.net~ He is also modest when he cooperates. It can be said that he has a very charming personality. people.

But you actually pried the corner of my wall when I was drunk! ?

"Don't think too much, Mr. Samejima just doesn't know the relationship between the two of us, and I have already made a choice."

Seeing Takagi's face-changing expression, Sato Miwako couldn't help but smile, and told Takagi what she did with the potted flower: "Otherwise, why do you think that potted flower is at Karasawa's place?"

"So this is ah…"

Speaking of this, Takagi was relieved, but at the same time, he was also very moved by Miwako Sato's silent rejection of others' pursuit.

But at the next moment, he seemed to react, looked at the potted flower suddenly, and then looked at the silent Samejima Ryuhei, with an expression of disbelief on his face: "Wait... so..."

"I never thought..." Miwako Sato sighed, "It would end like this."
