"What's a grimace?" Zhao Yu still didn't understand.

"A grimace is a special pattern on wood, it looks like a grimace, and the more grimaces you make, the more valuable it is!" Cui Lizhu said, "Also, the porcelain on his furniture is a fine product of hundreds of thousands or even millions." In my opinion, either Yuan Juncheng's wife didn't tell us the truth, or Yuan Juncheng didn't tell the truth to his wife!"

"Oh...... In other words," Zhao Yu nodded, "Yuan Juncheng's collection is all good goods, and there is moisture in the argument that they are donated to museums......! People are experts in cultural relics, so it's not an exaggeration to make a few collectibles, right!?"

"Boss," Cui Lizhu said with a worried face, "I'm a little confused now! Was Yuan Juncheng murdered? This thought was quite firm before, but now, it seems to be a little blurred......

"Oh, why do you say that?" Zhao Yu asked.

"You see," Cui Lizhu analyzed, "Yuan Juncheng had an incident at his own home, and when his wife came home and found out, he could still say that his heart was uncomfortable." If someone murdered him, why didn't he tell the murderer?

"Perhaps...... We can explain it with the statement that the murderer stunned him and drugged him!" Cui Lizhu frowned, "But, what kind of medicine is so powerful? Can a healthy person die of a heart attack? At least...... I've never heard of it!"

"Indeed!" Zhao Yu nodded, he had never heard of such a high-grade poison in the world? If Yuan Juncheng was poisoned, then the hospital would definitely be able to find out when he did an examination!

"But ......," Cui Lizhu said instead, "if Yuan Juncheng died of natural causes, it doesn't seem to be very like! He can still talk when he is sick, so why don't you call for help quickly? So...... Boss, I'm really confused now!"

"Alas!" Zhao Yu shook his head and sighed, "It's a pity that the body was not autopsied, and we missed the important evidence!"

"The body has already been cremated, right?" ...... Cui Lizhu smacked her lips, "So what should we do next?"

"Two ways!" Zhao Yu said decisively, "First, Yuan Juncheng was rescued in the hospital before he died, we should ask the doctor who rescued him to see if we can get any new information, or other evidence;

"Second, we should check the surveillance video of the community to see if there were any suspicious characters in Yuan Juncheng's house on the day of the crime?"

"Yes!" Cui Lizhu nodded, "Boss, you say, if there is really such a murderer, will he be Yuan Juncheng's acquaintance? Otherwise, how did he enter Yuan Juncheng's house?"

"I don't think it's very likely that an acquaintance committed a crime!" Zhao Yu inferred, "Since Yuan Juncheng didn't mention being framed before he died, it means that he hasn't seen the murderer either!"

"Then this murderer must not be simple, right? can open the door of Yuan Juncheng's house, and kill him unconsciously!" Cui Lizhu worried, "Really...... Is there such a person?"

"Yes!" Zhao Yu also sighed heavily, "The main thing I can't figure out now is what the murderer's purpose is in doing this? If Yuan Juncheng was murdered, why did the murderer kill him in such a way? Secretly poisoning, car accidents, or other means, but in Yuan Juncheng's house, he still has to pretend to have a heart attack......

"Hey, will it ...... What kind of chronic poison is it?" Cui Lizhu guessed, "The murderer didn't go to Yuan Juncheng's house at all that day, he just poisoned Yuan Juncheng in batches, and finally poisoned him?"

"I've thought of this too!" Zhao Yu frowned, "But, if it's a chronic poison, how can Yuan Juncheng have to react a little, right? But his physical condition has always been good!"

"Hmm...... It's too!" Cui Lizhu nodded.

"The most incomprehensible thing is, why did the murderer kill him?" Zhao Yu said again, "Even if it's to find treasure, there's no need to kill people?"

"Killing means extinguishing the mouth, will it be ......"

"You mean, Yuan Juncheng knows the secret of the treasure, and he was killed and killed?" Zhao Yu shook his head, "He is the former director of the museum, if he knew the secret of the treasure, should the treasure have been unearthed a long time ago?"

"This ...... This is too strange!" Cui Lizhu was speechless, "Treasure, murder, here...... What will it matter?"

"Or ......" At this moment, the two have come to the gate of the community, Zhao Yu said, "Let's divide the two soldiers! You go to get the community surveillance, and I will go to the hospital!" Saying that, Zhao Yu looked at his watch again, "When my people arrive in the afternoon, we will be more relaxed, but now, we must do it ourselves!"

"Oh, good!" Cui Lizhu snapped her fingers happily and turned to look for the community property.

Zhao Yu stopped a taxi and went straight to the hospital.

......

At two o'clock in the afternoon, Fengping Central Hospital, in the corridor outside the blood test department.

Zhao Yu was hiding in a secluded corner of the corridor, talking on the phone with Gao Facai's forensic doctor. Before that, he got an important clue from the emergency doctor who had rescued Yuan Juncheng.

The doctor told Zhao Yu that when he was rescued, he had done a blood test for Yuan Juncheng. The hospital has a clear rule that they are worried about errors in the blood sample of the patient, and the blood sample will be kept in the blood laboratory department for one to two months, and will be disposed of through professional channels after confirming that there is no dispute.

In other words, although Yuan Juncheng has passed away, his blood sample is still stored in the hospital!

This blood sample is obviously very important to Zhao Yu. If a sample can be found, perhaps the truth about Yuan Juncheng's death can be found!

Fortunately, although a month and a half has passed since Yuan Juncheng's death, the sample is still intact and preserved in the laboratory department!

Zhao Yu couldn't help but secretly congratulate himself on his wise decision, fortunately he took Yuan Juncheng as the first subject of investigation, if it was a few days later, I am afraid that this only blood sample would not exist!

"Hey, High Forensic Doctor, what are you ...... Are you still in Gaolanqi?" Zhao Yu asked familiarly into the phone.

"Write a report on the fire case!" Gao Facai smiled as unexpectedly, "There are still some inaccurate evidence, which must be examined in depth! Well, I saw Officer Miao just now! Why aren't you two together?"

"I'm in Zhaoyun Province!" Zhao Yu said with a smile, "Have you seen the test sheet I just gave you? I have another case here, can you help me see if there is a problem with that list?"

"Oh...... You really can't be idle!" Gao Facai exclaimed, "Okay, I'll watch it!"

"By the way, Lao Gao!" Zhao Yu looked left and right, and asked in a low voice, "Ask you something, do you know that in this world, there is a kind of medicine that can make people die of heart disease, but they can't be detected?"

"Well...... Gao Facai pondered for a moment and said, "The answer is a bit complicated! It depends on the victim's situation, if it is caused by allergy symptoms, it is generally difficult to determine whether he killed him! Does your victim have small acne or edema?"

"Hmm...... People have been dead for a long time, and they have been cremated!" Zhao Yu replied helplessly, "However, the deceased should have no allergic symptoms!"

"Is there a history of heart disease?" Gao Facai added, "If the deceased had a serious heart attack before his death, then the injection of dopamine or potassium, and some drugs that cause blood veins to expand, will cause the attack! If the injection content is well controlled, it is not easy to obtain evidence." ”

"No!" Zhao Yu hurriedly said, "The deceased is very healthy and has no history of heart disease!"

"That's not going to work!" said Dr. Gao, "If the injection volume is too high, it can be easily detected." Moreover, it is not necessarily fatal! If other poisons are used, they are also very easy to test!"

"Oh......" Zhao Yu nodded silently, muttering in his heart, it seems that Cui Lizhu is right, whether Yuan Juncheng died of murder or not, it is really difficult to say!
