The three of them ate dinner and rushed to Dr. Nan's office, just as they were about to enter the door, they heard a burst of laughter in the room, and there seemed to be a woman's voice during the period.

Fat man a face doubt, after all, the whole information heart and the male bathhouse, it is not easy to find a mother sparrow, this time there are guests to find Dr. Nan or a woman, is it really his "old girlfriend"?

Fat man fucked his head, not like!

The voice was very young, and the fat man looked back at Zhou Hai, and saw that his face was slightly suspicious, and instantly ridiculed his heart.

He pointed to the room in a low voice and asked, “Do you know the sea?”

"The voice is familiar, but this man should be in the provincial city?"

He said that he had just left to knock on the door, and did not expect the door to open in an instant, Dr. Nan tugged at the head to see Zhou Hai, and a face of surprise reached out to pull Zhou Hai into the room.

"Come, say Cao Cao Cao Cao, and see if this is the doctor of the week I told you."

With the introduction of Dr. Nan Wudao, sitting on the sofa, an old man looked over, the old man looked at the same age as Dr. Nan, but also a white hair, the suit of the body is full, let people have a little more British gentleman feeling.

The woman next to her was not old, and the old man had a five-pointed god, and the able-bodied zi-laid hair was accompanied by a small slap, with a hint of childishness, and at this time, his chin looked at Zhou Hai with interest.

Zhou Hai glanced at Dr. Nan Wudeo, saw that he did not introduce the meaning, slightly narrowed his eyes, can not introduce himself, indicating that this person must be familiar with himself, if it is said that there is only one person who knows and has not met.

Zhou Hai walked toward the woman, and said with a slight head: "Hu forensics, this is yours..."

Unwilling to wait for Hunan to react, the old man sitting on his side laughed up.

“Hurry up and give your granddaughter money, you’ve lost!”

This boy is really powerful, it is just a child who has just realized that the child is pursuing, and this ability to observe and analyze is really eye-catching!”

Dr. Nanwulu walked quickly and quickly stopped Zhou Hai before he spoke, because if he followed Hunan to call himself an instant to become a small generation of people, this verbal loss he did not want to eat, after all, this old man suppressed himself for a lifetime.

"Chou Hai you call this old thing Dr. Hu or old Hu, don't call Hunan Grandpa, in fact, little Hunan also called her Dr. Hu, old Hu, so don't mind."

The fat man behind Zhou Hai hurriedly bowed to Hunan's grandfather.

“Husday, good old man!”

Zhou Hai almost laughed out, fat man is afraid of his straight man cancer, quickly make a demonstration, Zhou Hai looked at the Hunan who is staring at his own, toward Hunan's grandfather again.

“Husday, good old man!”

Dr. Nan Wukou was relieved, greeted the people to sit down, and Hunan looked at Zhou Hai with a suspicious face.

"Well, I heard Dr. Nan say some things, so that you can easily tell what you know?"

The fat man looked at Zhou Hai, saw that he did not stop his movements, and said all the progress of the case in the past few days, especially the discovery of the afternoon.

This made Hunan and his grandfather a little shocked, and then Hunan, under the motion of Hu Lao, opened a laptop computer and found a picture.

Hu Lao pointed to the two pairs of the computer, pointed out the position of the circle with different colors, and said:

“I’ve seen some of the pictures I’ve seen!

You see here, in this cross-linked position, there is a pause to reverse the action, such as if the right hand to write this position will be very smooth, and the left-hand book seems to be a bit of stutter, but you see these two fonts have such a stutter state.

And the rest of the right I made with different colors, there are similar places in it, although not very obvious, and deliberately avoid the habit of writing, but I still think it is written by the same person."

Hu Nan saw Zhou Hai close to the computer, especially the right eye from the computer, carefully look at the calligraphy work, medical record card and the message next to the six-pointed star, Hunan micro-scratched eye, is Zhou Hai's left eye vision problem?

After watching it, I looked up at the old man again.

“Do you mean that these writings come from the same hand?”

Hu nodded, "Ninety percent sure it's the same person, but some are right-handed writing, some are left-handed writing, but they are all written by the same person, and these writings have different ages."

To get such an accurate answer, you can prove that Yang Duxiu is the mastermind behind this serial case, and the murderer of the Lu Xi case and Dongbin case, Zhou Hai suddenly thought of the chemical molecular analysis below the keyboard.

Quickly touch the phone, find this picture, and hand the phone to Dr. Nan.

"I forgot to ask you, Dr. Nan, that the papers seem to be counting on something, and I've looked at a record of similar experiments, but I have a lack of knowledge about it, and I hope you will see it."

Nan Wukou took the phone and looked at it and directly threw it to Hunan.

"You don't have to put a professional staff, to let the South-South look, to know that her university is a pharmacy major, but later changed to this."

Zhou Hai looked at Hunan, originally she was also changed, can do today's position, it can be seen that she is also a very hard-working person.

Hu Nan looked at the molecular formula again, turned the laptop around, searched it, saw the results sluggish, and estimated it on the paper again.

“This is a purification test, which is being used for purification, which is the process of mixing impurities, but only 2h+k2co3 is produced chemical products.”

The fat man was a little confused, and looking at this long string written by Hunan, it was a embarrassed expression.

“What’s the matter, to say it’s bad?”

Zhou Hai patted him on the shoulder and explained: "This is potassium, no wonder I feel familiar, it turns out that he did not finish the final calculation, I seem to have seen this chemical formula in the laboratory of the eldest sister, but I do not know whether it is consistent."

Hunan looked up at the sea.

"This is a complex, the added impurities will be slightly different, don't tangled these, but I am interested in how he synthesizes it, from where to get the raw materials?"

Zhou Hai recalled a little, "before I was in the case of the poisoning of the Tuping, I always thought that the murderer would be exposed to the work of gold mines, after all, it is not very easy to get these compounds, and some of the old mining of the gold mine can still get the best things."

Hunan nodded and shook his head again.

"No, if the mine gets the ** things will not be calculated in this way, after all, the purification process is still very strict, simple equipment can not be completed."

“Did you find the killer’s studio, or the location of the synthesis?”
