[553 Doubtful Points of Death]

Ah Zi's speed was very fast, and after a while, they arrived at their destination.

Although the Du family is not a famous family, because of the rise and prosperity of the family pharmaceutical company in the early years, it still has a certain reputation in the local area, but because of the poor management later, it also fell day by day, and finally led to the collapse of the company, and only recently announced the bankruptcy of the family, and took on a lot of foreign debts.

The Du family has three daughters and one man, and the three sisters are married separately, and the only one left is the husband who Wei An married-Du Sheng.

Du Sheng was selfless and kind all his life, gentle and peaceful, he was a top student in the Department of Psychology, and began to accept the family business after marriage, but he was found to have a serious illness soon after he was newly married.

When Tang Sa introduced these to Yan Xiaoyu, Xiaoyu was already in unbearable pain for Wei'an, and his hands in his sleeves were also clenched into fists, but he was afraid of leaking his expression, so he endured it all the time, and he only felt sad.

"The Du family is in the middle of the road, and there are many foreign debts, but they have not declared bankruptcy, because half a year ago, Master Du took over a new business, intending to use it to revitalize the family business again. However, Young Master Du was stubborn and innocent all his life, and always insisted on not approving the sale of this kind of imported private drugs without a batch number, and the father and son disputed and refused to give in to each other, because of the symptoms, in a fit of anger, the seriously ill Young Master Du decided to try the medicine himself, and later found that there was a difference, so he stopped for a while, but for some reason, after three months, Young Master Du, who was in stable condition, died suddenly. ”

Tang Sa explained, and his eyes fell on the servants of the Du family who were cleaning up and setting up the mourning hall.

Yan Xiaoyu quickly grasped the point of his words, twisted his eyebrows and said, "Then, that is to say, either there is a problem with the medicine, or there is a problem with the people of the Du family." ”

"I have secretly investigated the Du family, the three sisters have loved Young Master Du since they were children, and there is no dispute over ancestral property, only this one son, it is even more impossible for Master Du to poison and eat children, so this problem is obvious."

He paused, and Xiao Yu answered, "It's out of the medicine?" ”

"After a brief investigation, a few months before Young Master Du's death, except for the Du family and some partners who often come and go in business, I only saw two men who behaved strangely at different times."

"Strange behavior?"

As soon as Xiaoyu's question fell, the assistant Ah Zi beside him had already taken out some thick photos taken from the surveillance and handed them over-

The photo is blurry.

I couldn't see the faces of the people inside clearly, but I could see Young Master Du and a man standing in front of a black car talking from a distance.

The man was dressed casually, about 1.8 meters tall, with broad shoulders and slender legs, the standard athlete height, a beautiful hanger, but he could only see his back, not his face.

Xiao Yu flipped down one by one, and when she flipped to the last one, she saw that another man, also known as another familiar figure, came into view.

Leather jackets, hats, gloves, airtight masks.

Although I have never seen his face, there will never be a second person in this same outfit!

At this time, she found out that the location here was an underground parking lot.

This parking lot is not far from City A, and the sanatorium where Zhan Lei is located is right!

Xiao Yu's face turned pale, and he immediately turned around, walked to the corner, and called the dean as Miss Mu's friend.

"Oh, Dr. Yang, he resigned after giving Miss Mu medicine, saying that he was hired by other hospitals for a lot of money, and I can't contact him now! What, medicine? I don't know if there are any drugs for sale, but the medicine he gave to Miss Mu was delivered from Germany, and although I have friends in the military hospital, I mainly rely on Dr. Yang to contact them...... Mr. Zhan, he's fine, he's still lying in the ward, and we've been working overtime to guard him according to Miss Mu's instructions for the past few days. ”

"Okay, dean, thank you, Miss Mu will visit the nursing home in the past two days, and she will decide whether to use new drugs or not."

Hung up the phone, Xiaoyu's face became heavy-

A bold, incredible, and highly probable speculation gathered and formed in her mind, making her chest throb wildly, and making her even more nervous, nervous about what she had been tracking for years, and finally began to reveal its feet and clues......

"Officer Ho?!"

Someone patted her shoulder behind her, looking back, maybe it was because they had waited too long, Ah Zi ran over to call her, pointed to the villa at the main entrance of the Du family and said, "Uncle Tang has already entered, and said that he wants to take a look at Mr. Du's room, do you want to go with him?" ”

Xiao Yu nodded, and stepped on his heels.

Du Sheng's room is very neat, clean, regular and tidy, you can see that it is meticulous and conscientious and delicate, and you can also see some of his innate stubbornness from the neat and uniform placement of books on the shelves.

Because of the name of Mrs. Yan Wei'an, the servants knew each other very well and did not stay, and only the three of them were left in the house.

Ah Zi stood in front of the window and looked left and right, Xiao Yu began to look through some of Du Sheng's writings, and Tang Sa began to check some of Du Sheng's computer information, although they all had passwords, they were all easily cracked by him.

"How, what did you find?" Ah Zi came over and asked, "Will you leave a suicide note or something?" ”

"It's not a suicide, and it generally doesn't leave a suicide note. The results of the examination in the hospital here also showed that half a month before he died of serious illness, Du Sheng also went for an examination, and showed that there was no problem, and the step-by-step treatment was improving, so it was not a case of serious illness. Xiao Yu analyzed, shifted his gaze, and finally settled on a small locked box on the top floor of the bookcase, and walked up.

Ah Ziyan was quick, stepped forward, stepped on the stool and took it down, and handed it to Xiao Yudao, "Do you know how to pick the lock?" ”

Xiaoyu smiled.

He took out a pair of extremely thin and soft iron wire with a curved arc from his pocket, inserted it into a delicately made gold lock, closed his eyes and twisted it, and clicked.

The lock is open.

Ah Zi exclaimed, "Wow, that's amazing!" ”

"It's nothing," Xiao Yu took the wire and didn't care, "This is the basic course of the FBI." ”

Then, Xiao Yu opened the iron box and saw a note full of garbled characters, and without saying a word, he sat down, picked up a pen and paper and began to write and draw.

Ah Zi lowered his head and asked, "What is this?" ”

"The symbolic cipher, which evolved from the Morse code, needs to be cracked."

As she spoke, in just a few dozen seconds, she had cracked out some messy digital English and Chinese character strokes.

There are no rules, no rules.

"Double password", Xiao Yudao, "After cracking, you have to look for the combination law, otherwise, you can't find any useful information." ”
