Detectives of Detective World

The investigations of both sides have progressed in stages at the same time, which should be a gratifying thing.

But instead of double the exhilaration, this double progress is endless emptiness.

Because both the sodium carbonate found by Tang Ze and the alibi about Yamamura Kage found by Gongchang Criminal all pointed the prisoner to a prisoner with professional knowledge.

It is equivalent to saying that after the interrogation of Yamamura Shadow, Tang Ze judged that what the other party said was the truth, and the inference that he was not a prisoner was confirmed.

Although this guy is a potentially pleasant criminal, he is not a criminal.

Of course, although the other party cannot be arrested just because the other party has dangerous thoughts, the necessary follow-up is still needed.

After exchanging information with the other party, Tang Ze reminded Chief Gong of the police department that he must send someone to pay more attention to the other party, and then hung up the phone.

"What are we going to do next?"

Seeing that Tang Ze finished the phone call, Takagi said with some distress: "Although it is known that the ignition point was caused by a substance containing sodium carbonate, it is very likely that the suspect is also a professional.

But there are too many candidates who meet the conditions, and we have no way to start now. "

"Suspects can be ruled out slowly, but for now, let's start with channels."

Tang Ze thought for a while and said, "After all, even if the fire is caused by sodium carbonate, all the substances in it cannot be the same.

If we can find the same fire as the sample collected, then the channel is identified, which should narrow the scope to a certain extent. "

"Sodium carbonate is not so easy to get." Takagi said suddenly: "It is indeed a good way to start from this aspect."

"In fact, it is very simple for professionals. As long as there is a certain acid and glycerin, nitroglycerin can be made."

Tang Ze said: "For example, 50% of enemas are glycerin, which can be said to be easy to buy.

After a while, we will go to the pharmacy, buy all the enemas on the market, and then compare it with the sodium carbonate on hand after an experiment.

As for the things that acid is not so easy to obtain, it feels that the prisoner has what he has on hand. We can replace it with several common acids. "

"So, do you have to trouble Mr. Saito?"

Hearing this, Takagi looked at Tang Ze and said, "You just said to let him rest, are you planning to let him take on this huge workload?"

"That's not true." Tang Ze waved his hand and said, "For such a simple comparison task, just leave it to your subordinates. Let's go and buy an enema first."

After going around Tokyo with the funds and buying all the brands of enemas, the two returned to Kesouyan and began to squeeze the labor force of their employees.

Fortunately, the operation of the scientific research institute is in good condition, and the advanced technology has also provided logistics services for the Metropolitan Police Department, and the personnel are also recruited again and again.

Coupled with the task assigned by Tang Ze, his immediate boss, the efficiency is still very high.

The exhaustive method quickly produced results with the cooperation of the human sea tactics, but it was disappointing that the various combustion residues they tested were completely different from the fire scene.

Although it is true that sodium carbonate is formed, other trace impurities are completely different.

These trace impurities are equivalent to a kind of "fingerprint". Only when the same substances are fused and burned will they get basically the same magazines.

Without this impurity, it is equivalent to the prisoner not using these things to make nitroglycerin.

"That means it wasn't nitroglycerin that caught fire?" Takagi said with disappointment after getting the results of this large-scale experiment.

"No, the general direction is correct."

Tang Ze shook his head and said, "But we still don't know what the specific manufacturing materials are. This is a good thing and a bad thing."

The good thing is that the prisoners use special materials to make nitroglycerin, and if they can find them, they can directly lock the prisoners.

But the bad news is that it's like looking for a needle in a haystack, and if you can't find the special material, nothing starts.

Sure enough, even though Tang Ze finally brought Saito Hiro to think about it, he still didn't think of what special material the prisoner used to synthesize nitroglycerin.

And this kind of thing should be very common.

For example, a chemistry teacher, although it is indeed easy to come into contact with acids that can synthesize nitroglycerin, these things are strictly managed by the school.

If you don't want to be discovered, you can only use things that are easier to get your hands on.

With full of doubts, Tang Ze returned home.

"You're back. Aunt sent crabs from Hokkaido today. Let's have this for dinner."

As soon as he entered the door, Tang Ze saw that Ayako was busy working. He also put down his work and walked into the kitchen with a smile: "Crabs, it's really good, I haven't eaten it for a long time."

"According to my aunt, they are all freshly fished and then refrigerated, and then expedited to deliver." Ayako smiled.

"But why did I only know about this kind of thing last." Tang Ze glanced at the king crab in the foam cooler and said speechlessly.

"Prove that I am the master of the family." Ayako said proudly: "You no longer have the right to speak!"

"It's easy to say, but the right to speak in the bedroom must be mine."

Tang Ze smirked and stretched out his arms to hug Lingzi, who was slapped with a slap by the other side and gave a blank eyeball: "I know what I think about every day, and I haven't eaten yet."

"Okay, eat and eat." Tang Ze said with a smile: "I'll change my clothes and come over to help later."

"Then I'll make the miso soup, and leave the crabs to you." Ayako pointed to the side: "The knives are already prepared over there."

"OK."

Tang Ze went to the bedroom to change his clothes into home pajamas, and then began to dismember the crab.

Tang Ze's mother sent king crabs, which are the most plump from November to March every year.

Although it is a bit late now, it is still in time for the season.

Tang Ze first removed the crab's claws one by one, and then he cut them open one by one with scissors. Although it was troublesome to handle, Tang Ze gained a little more motivation when he saw the crab's legs full of crab meat.

On the other hand, Ayako wrapped the crab meat prepared by Tang Ze in a coat and processed it.

The king crab crab roe is not the best among the three major crabs in Hokkaido, but the plump meat of the crab legs is a must.

Tang Ze was looking forward to making it into tempura.

Of course, Tang Ze specially left three sections to split it. After a little roasting, he smeared mayonnaise on it, intending to taste the taste of baked crab legs.

As for the crab yellow in the middle, although it is not as good as the other two crabs, it cannot be wasted.

Tang Ze first cleaned the stomach and gills, and then began to examine the crab roe.

Unfortunately, due to the season, the crab roe is not so full, almost one third empty.

Gu 粨

Tang Ze used the shell of the upper body as a small bowl and poured all the crab roe into it.

Because Ayako had cleaned the crab shells before Tang Ze came back, she didn't have to worry about hygiene.

At this point, "one crab and three eats" is done, but when Tang Ze has dealt with these two things, Ayako's side has just started.

After all, these two of Tang Ze's are baked, and you can wait to eat them when you put them on top.

But tempura is a kung fu job, and it is not so easy to fry tempura with just the right temperature.

Of course, Ayako's cooking skills can be said to be full, and the tempura is fried just right.

But the first thing the two ate was crab meat tempura. After all, the two took too long to bake, but they were ready to eat right out of the pan.

The delicious crab meat and noodles bloom in the mouth, and it can be said that it is very delicious with rice.

Then came the crab meat baked with mayonnaise. Because it was his first experiment, he didn't dare to do more but just tried the taste.

Take out the baking pan, the original crab meat has been covered with golden brown.

After biting into the shell that looked like grilled cheese, an aroma erupted in the mouth immediately, and the roast was so rich that the mayonnaise and crab meat fused, instantly grabbing the stomachs of the two of them.

"This is delicious." Ayako's eyes lit up after tasting it: "Where did you see the good way?"

"My friend told me." Tang Ze perfunctory, it can't be said that he learned from eating and broadcasting in his previous life.

The two worked together to sweep away a few crab legs. Of course, most of them were eaten by Tang Ze. With his current physical fitness, his appetite was actually quite large.

"I'll go get the crab roe, and we'll eat crab roe bibimbap."

Tang Ze got up and went to the kitchen, but when he came back, he saw that Ayako was gesturing around with the flowers she brought back yesterday.

"I was eating, why did you get up?"

Tang Ze looked at Ling Zi, who seemed to be choosing the location of the flower pot, and said in surprise: "Also, what are you doing with that pot of flowers?"

"Eh? Didn't your friend give you this?"

Hearing Tang Ze's words, Lingzi held the flower with a surprised look on her face: "You brought it back after you finished drinking yesterday. I thought you went to a friend's house for dinner, and your friend gave it to you."

"Ah, I forgot to mention it yesterday when I was so excited." Tang Ze patted his forehead and told Ayako what happened yesterday.

"It turned out to be given to Sato Criminal. She gave it to you to reject Mr. Shashima."

Ayako looked at the flowers in her hand with a pity: "It's a pity that the flowers are so good that they haven't been given to those who have owners.

It can be seen that Mr. Shashima is very attentive to fertilize and water the flowers. "

"and many more."

Tang Ze stopped what he was doing and turned his head to look at Ayako: "What did you just say!?"

"Huh?" Ayako repeated subconsciously after seeing Tang Ze's words: "I said such a good flower..."

"It's not this sentence." Tang Ze interrupted Lingzi's words, "It's the next sentence."

"I said that Mr. Shashima is very attentive in fertilizing and watering the flowers." Seeing Tang Ze's stunned appearance, Ayako didn't look strange, but she was very cooperative and repeated her words. again.

After all, for her, having a husband who is a criminal is like this, and occasionally there will be occasions where she reminds the other party with a casual sentence.

If you guessed correctly, the other party will be thanked by the other party for their contribution.

And just as this thought fell, the next moment Ayako felt that the whole person was being hugged.

"Thank you very much, you are my lucky star." Tang Ze kissed Ling Zi on the cheek: "You have made a great contribution!"

"It's good to be able to help you." Ling Zi smiled at Tang Ze's excited look: "As a thank you, you can quickly resolve the case and then take a vacation."

"Okay." Tang Ze just nodded, his nose moved slightly to look at the crab shell on the side with the crab roe, his face changed: "Oops, the crab roe has been roasted."

In a hurry to rescue the crab yellow, Tang Ze tasted it and breathed a sigh of relief.

Fortunately, it was only slightly overcooked, with a slight bitter taste, but it was not scrapped.

After stumbling over the rice and adding a little seaweed and sesame seeds, Tang Ze tasted it and breathed a sigh of relief.

Fortunately, a little bit bitter but has a different flavor, which is not bad.

Feed Ayako a couple of bites with a spoon and let her taste it, and the rest of Tang Ze directly swept it away.

After dinner, the two went out to watch an opera, and then returned home leisurely.

Although Tang Ze came up with a breakthrough clue through Lingzi's inadvertent reminder, Tang Ze didn't lose his temper so much that he didn't even care about life, so he plunged into work.

Moreover, this verification also requires a huge workload, and it will not be urgent for a while.

The next morning, Tang Ze didn't go to work early, but took a rest at home after eating, and didn't go out until eight o'clock.

And his destination is not the Metropolitan Police Department, but Tokyo's largest fertilizer store.

That's right, what Ayako said yesterday reminded him of an important piece of information, or let him come out of his misunderstanding.

Glycerin can be easily obtained in enemas, and although simple "acid" is not so easy to obtain, some things have "acid" attached, which can achieve the same effect.

And horticultural fertilizers are one of the most common substances that may contain the element "acid".

With a big wave of his hand, Tang Ze bought all the fertilizers on the market, and asked people to put things in the trunk of his bike.

Fortunately, although there are a lot of fertilizers, they are all in small bags. Even a bag of Tang Ze's trunk can be put down. Otherwise, he would have to hire someone to drive a truck to send it to the scientific research.

However, when he came to the laboratory department with a large amount of fertilizer ~www.NovelMTL.com~ still caused a wailing.

After all, the previous workload was enough to destroy them. I didn't expect to do it again this time, and the workload was even greater.

After all, this time, it is to mix fertilizer and enema, and then see if it can match the magazine at the crime scene.

Just thinking about that huge combination makes everyone's scalp tingle.

"Okay, I know that this time the workload is heavy, I will give you overtime pay."

Tang Ze hugged the pot of flowers and said with a smile: "It's hard work, now go to my car and pick up the fertilizer, and by the way, buy something to eat and drink, I'll treat you."

Hearing Tang Ze's double encouragement, the faces of the researchers brightened.

But thinking of the terrifying workload, everyone still couldn't help sighing.

And after Tang Ze became the shopkeeper, he felt more and more that it was a wise choice to promote the establishment of "Kesou Research" at that time.
