Advocate for the deceased

Chapter 389 White spot reappearance (31)

The three of them rushed to Dr. Nan's office after eating, and when they were about to enter the room, they heard bursts of laughter coming from the room, and there seemed to be a woman's voice during the period.

The fat man looked puzzled. After all, the entire information center looked like a men's bathhouse. It was not easy to find a female sparrow. At this time, a guest came to find Dr. Nan or a woman. Could it be his 'old girlfriend'?
The fat man shook his head, not like that!

The voice was very young, the fat man turned his head to look at Zhou Hai, seeing the slight doubt on his face, his heart of teasing immediately flourished.

He pointed to the room with his mouth in a low voice and asked, "Do you know Haizi?"

"The voice is a little familiar, but this person should be in the provincial capital?"

As he spoke, he stretched out his hand and was about to knock on the door, but unexpectedly the door opened instantly. Dr. Nan stretched his head just in time to see the two of Zhou Hai, and stretched out his hand to drag Zhou Hai into the room with a look of surprise on his face.

"Come, come, say Cao Cao Cao Cao is here, and see that this is the forensic doctor Zhou I told you about."

Following the introduction of Dr. Nan Wudao, the old and the young sitting on the sofa looked sideways. The old man looked about the same age as Dr. Nan, with gray hair and a neat suit, which made people feel a little more like a British gentleman. .

The woman next to her was not very old, and she was very similar to the old man. She had short ear-length hair and a small face the size of a palm, with a hint of childishness. She raised her chin and looked at Zhou Hai with interest.

Zhou Hai glanced at Dr. Nan Wudao, seeing that he didn't intend to introduce, he narrowed his eyes slightly. The fact that he didn't introduce himself like this meant that he must be familiar with this person.

Zhou Hai walked towards the woman, nodded slightly and said, "Doctor Hu Fa, this is yours."

Before Hu Nan could react, the old man sitting beside him raised his head and laughed.

"Hurry up, granddaughter, give the money, you lose!

This kid is really amazing, he is indeed sought after by a kid who has just realized the Tao. This observation and analysis ability is really impressive! "

Dr. Nan Wudao walked over quickly, and stopped Zhou Hai before Zhou Hai opened his mouth, because if he followed Hu Nanlai and called himself a member of the younger generation, he didn't want to take this verbal loss, after all, this old guy suppressed him. own life.

"Zhou Hai, you can just call this old thing Dr. Hu or Mr. Hu. Don't call her Grandpa just like Hu Nan. In fact, little Hu Nan also calls her Dr. Hu and Mr. Hu, so don't mind."

The fat man behind Zhou Hai quickly bowed to Hu Nan's grandfather.

"Hi Mr. Hu!"

Zhou Hai almost laughed out loud. The fat man was afraid that his straight man would have cancer, so he hurriedly made a demonstration. Zhou Hai glanced at Hu Nan who was staring at him, and nodded again at Hu Nan's grandfather.

"Hi Mr. Hu!"

Dr. Nan Wudao breathed a sigh of relief and asked everyone to sit down. Hu Nan looked at Zhou Hai suspiciously.

"Okay, let's get back to business. I heard Dr. Nan said something about it. Would it be convenient for you to tell me what you know?"

The fat man glanced at Zhou Hai, seeing that he didn't stop his actions, he told all the progress and discoveries of the case in the past few days, especially the discoveries in the morning.

Hu Nan and his grandfather were a little shocked by these words, and then Hu Nan opened a laptop under Hu Lao's gesture, and found a comparison chart.

Pointing to the two comparison pictures on the computer, Mr. Hu pointed out some places with circles drawn in different colors, and said:

"I took a closer look at the pictures sent by Wu Dao!
Look here, the position of the horizontal folding hook above has a pause and twisting movement. If it is written with the right hand, this position will be very smooth, while the left-handed book will appear a bit stuck, but you can see that these two fonts have such a card. ton state.

As well as the rest of the comparisons I made with different colors, there are similarities in them. Although they are not very obvious, and they deliberately avoid writing habits, I still think they are written by the same person. "

Hu Nan saw Zhou Hai approaching the computer, especially his right eye was very close to the computer, carefully looking at the calligraphy work, the medical record card and the message next to the hexagram, Hu Nan frowned slightly. Could it be that Zhou Hai has a problem with his left eye vision?

After Zhou Hai finished reading, he looked up at Mr. Hu again.

"Mr. Hu, do you mean that these writings are all written by the same person?"

Mr. Hu nodded, "[-]% sure it is the same person, but some are written by the right hand and some are written by the left hand, but they are all written by the same person, and these writings have different age groups."

Being able to get such an accurate answer can prove that Yang Duxiu is the mastermind behind this serial case, and also the murderer of the Lucy case and the Dong Bin case. Zhou Hai suddenly thought of the chemical molecular analysis formula that Yang Duxiu pressed under the keyboard.

Quickly took out the phone, found this picture, and handed the phone to Dr. Nan.

"Dr. Nan, I forgot to ask you before. These papers seem to be checking something. I looked at it like an experiment record, but I lack knowledge in this area, and I hope you can show it."

Nan Wudao took the phone and looked at it, then threw it to Hu Nan.

"You don't need the professional staff, let Nan Nan take a look. You should know that she majored in pharmacy in college, but she changed her career to study this later."

Zhou Hai raised his eyes and glanced at Hu Nan. It turned out that she also changed her career. Being able to achieve her current position shows that she is also a very hardworking person.

Hu Nan looked at the molecular formula, turned the laptop around, and searched for it. He was startled when he saw the result, and calculated it again on paper.

"This is a purification and mixing experiment. It is purified when it is used, and it is the process of mixing impurities when it is used. However, the chemical product obtained is only 2HCN+K2CO3."

The fat man was a little confused, looking at the long list written by Hu Nan with a dazed expression.

"What the hell is this? Just say that the result is not good?"

Zhou Hai patted him on the shoulder and explained: "This is potassium cyanide. No wonder it looks familiar. So he didn't finish the final calculation. I seem to have seen this chemical formula in Sister Zeng's laboratory, but I don't know if it is consistent. .”

Hu Nan looked up at Zhou Hai.

"This is a compound, and the impurities added in it will be slightly different. Don't get entangled in these, but I am interested in how he synthesized it, and where did he get the raw materials?"

Zhou Hai recalled a little, "When I was in the poisoning case in Duping, I always thought that the murderer would work in the gold mine. After all, it is not very easy to get these compounds, and some old mines on the gold mine can still get cyanide. of."

Hu Nan nodded, then shook his head again.

"No, if it is the cyanide obtained from the mine, this method will not be used to calculate it. After all, the purification process is still very strict, and simple equipment cannot complete it.

By the way, have you found the murderer's studio, or the compositing location? "
