"What is a ghost face?" Zhao Yu still didn't understand.

"Ghost faces are a special pattern on the wood. They look like grimaces. The more grimaces they produce, the more valuable they are!" Cui Lizhu introduced, "Also, the porcelain placed on his furniture is each of the fine products worth hundreds of thousands or even millions. I think, either, Yuan Juncheng's wife did not tell the truth to us; or, Yuan Juncheng did not tell the truth to his wife!"

"Oh...that is," Zhao Yu nodded, "Yuan Juncheng's collections are all good goods, and it is very hydrated to donate them to museums! But... they are cultural relics experts themselves, so it is not an exaggeration to create a few collections!?"

"Boss," Choi Lizhu said with a worried look, "I'm a little confused now! Did Yuan Juncheng be murdered? This idea was quite firm before, but now it seems a little blurry..."

"Oh? Why do you say that?" Zhao Yu asked.

"Look," Choi Lizhu analyzed, "Yuan Juncheng was involved in something at his own home. When his wife came home and found out, he could still tell that his heart was uncomfortable. Think about it, if someone murdered him, why didn't he tell the murderer?

"Maybe...we can explain it by the murderer's explanation of the murderer's confusion and drug him!" Cui Lizhu frowned, "But what medicine is so powerful? Can a healthy person die of a heart disease? At least...I have never heard of it!"

"Indeed!" Zhao Yu nodded. He had never heard of such advanced poisons in the world? If Yuan Juncheng was poisoned, then the hospital would definitely find out during the examination!

"But..." Choi Lizhu turned and said, "If Yuan Juncheng died naturally, it doesn't seem to be very similar! He can still speak when he is sick, so why don't you call for help immediately? So... Boss, I'm really confused now!"

"Oh!" Zhao Yu shook his head and sighed, "It's a pity that the body was not subject to an autopsy. We missed the important evidence collection!"

"The body has been cremated, right? Tsk tsk..." Cui Lizhu smacked her lips, "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 could get any new news 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 family on the day of the incident?"

"Yes!" Cui Lizhu nodded, "Boss, do you think, if there is such a murderer, would he be Yuan Juncheng's acquaintance? Otherwise, how did he enter Yuan Juncheng's home?"

"I think it's unlikely that an acquaintance will commit a crime!" Zhao Yu inferred, "Since Yuan Juncheng did not mention the framed incident before his death, it means that he had never seen the murderer!"

"Then this murderer must be not simple, right? He can open the door of Yuan Juncheng's family and kill him without knowing it!" Cui Lizhu was worried, "Is there really... such a person?"

"Yes!" Zhao Yu also sighed heavily, "What I can't understand now is what the murderer did this is what purpose? If Yuan Juncheng was murdered, why would the murderer kill him in this way? Secretly poisoning, car accidents, or other means, but he was at Yuan Juncheng's home and pretended to be a heart attack..."

"Hey? Could it be... what kind of chronic poison is it?" Cui Lizhu guessed, "The murderer had never been to Yuan Juncheng's home that day. He just poisoned Yuan Juncheng in batches and eventually poisoned him to death?"

"I have thought of this too!" Zhao Yu frowned, "But if it was a chronic poison, Yuan Juncheng would have to react a little, right? But his health has always been good!"

"Well...so!" Cui Lizhu nodded.

"The thing I can't understand the most is why the murderer killed him?" Zhao Yu said again, "Even if it's to find treasure, there is no need to kill anyone?"

"Murder means silence, will it..."

"You mean, Yuan Juncheng knows the secret of the treasure? He was killed and silenced?" Zhao Yu shook his head, "He is the former director of the museum. If he knew the secret of the treasure, would the treasure have been discovered long ago?"

"This...this is so strange!" Cui Lizhu was shocked, "Treasure, killing, what's the matter with this?"

"Or..." At this moment, the two had arrived at the entrance of the community. Zhao Yu said, "Let's split into two groups! Go and retrieve the community surveillance, I'll go to the hospital!" As he said, Zhao Yu looked at his watch again, "When my people arrived in the afternoon, we will feel more relaxed, but now we must do it ourselves!"

"Oh, okay!" Cui Lizhu snapped her fingers readily and turned to find the community property.

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

...

At 2 pm, in the corridor outside the blood laboratory department of Fengping Central Hospital.

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

The doctor told Zhao Yu that when he was rescued, he had performed a blood test on Yuan Juncheng. The hospital clearly stipulated that they were worried that there would be errors in the patient's blood sample test. Generally, blood samples would be kept in the blood laboratory for one to two months. After confirming that there was no dispute, they would be disposed of through professional channels.

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

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

Fortunately, although it has been a month and a half since Yuan Juncheng's death, the samples are still preserved in the laboratory intact!

Zhao Yu couldn't help but secretly glad that he had made his wise decision. Fortunately, he took Yuan Juncheng as the first investigator. If he had been a few days later, this only blood sample would probably not exist!

"Hey, Forensic Gao, why are you... still in Gaolanqi?" Zhao Yu asked familiarly at the phone.

"Writing a report for the fire case!" Gao Facai was as serious as before, "There are some evidences that cannot be grasped correctly, and they need to be tested in depth! Well, I saw Officer Miao just now! Why are you two not together?"

"I'm in Zhaoyun Province!" Zhao Yu smiled, "Did you see the test form I gave you just now? I have another case here. Please help me see if there is any problem with that order, right?"

"Oh... you can't stay idle!" Gao Facai exclaimed, "Okay, I'll see now!"

"By the way, Lao Gao!" Zhao Yu looked around and asked in a low voice, "Ask you something, do you know, is there any medicine in this world that can kill heart disease but cannot be detected?"

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

"Well... the person has been dead for a long time, and it has been cremated!" Zhao Yu replied helplessly, "But the deceased should have no allergic symptoms!"

"Do you have a history of heart disease?" Gao Facai said again, "If the deceased had serious heart disease before his death, then injections of dopamine or potassium, as well as some drugs that cause blood dilation, will cause the disease! If the injection content is well controlled, it is not easy to collect evidence."

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

"That won't work!" said the forensic doctor. "If the injection amount is too high, it will be easily detected. Moreover, it may not necessarily lead to death! If other poisons are used, it will be easy to test!"
