Yang Zesheng had seen the two things in Qi Jing's hand, which were worn by Ye Han when he was traveling in China.

The ornament on the key ring is a kettle similar to a small gourd. It has a strange shape and is painted with strange yellow and blue pigment patterns. In fact, it looks no different from ordinary handicrafts.

The pink bead string looks like glass beads at first glance, but if you look closely, you will find that there are actually some white stripes mixed inside, two of which have a faint crack. Because of this, Yang Zesheng did not take these beads seriously, thinking that they were just a few bucks that could be seen everywhere, just like the kettle on the key ring.

"This shouldn't be cheap."

Qi Jing didn't have any in-depth research on ore, but when he was aided by Yunnan, he had a good relationship with some local people selling jade, so he just learned two tricks.

This bead is obviously not jade, and he doesn't know what it is, but at least he knows that the price is definitely not comparable to the kettle ornament, and it won't be too cheap: "This kind of stone is not a gem, it will have flaws, and the quality is too single, but it is made by hand. And the portion is not light, what mineral should it be."

After looking at Qi Jing who raised his hand and weighed him, Yang Zesheng was puzzled: "What does beads have to do with her heart?"

"Then I don't know..."

Qi Jing said this, but in his opinion, anything he didn't know could actually develop into clues, and sometimes he would miss it if he didn't pay attention.

After experiencing so many things before, it would be difficult for him to find clues if he hadn't been suspicious. If he could not find any clues, there would be no traceability and diagnosis later.

Now most of Ye Han's personal belongings are ordinary daily necessities, which look clean and does not affect his heart. After a meal, these three things in front of him were the most suspicious: gourd-like kettle decorations, red beads and a faint tea-scent on his clothes.

If the origin of the thing is unknown, it may be toxic if used too much, and the specific symptoms of poisoning are caused.

In Qi Jing's memory, there seems to be only one poison that can cause organic changes in the heart, cadmium. When it comes to cadmium, we have to mention that in Japan, the group cadmium poisoning incident was not a joke. (1)

But after all, it was back then, so it was wrong to label old things.

However, the spirit of Japanese craftsmanship has long been engraved into the bones. After the accident happened, the company involved actively handled related matters in accordance with judicial procedures. After the number of plaintiffs exceeded 500 and the number of lawyer team exceeded 300, they finally bent down sincerely and assumed the corresponding responsibilities.

In fact, there are still some objections to whether the pain is really caused by cadmium wastewater, but after losing the case twice in a row, the company did not struggle anymore.

Anyway, the poisoned civilians have already died almost.

From the perspective of symptoms, cadmium poisoning does cause pain in the bones and joints, and the pain will gradually increase, and even breathing will be painful in the end. In a sense, Ye Han's muscle pain may also be bone pain, after all, the symptoms of the ribs have always existed. (2)

However, Qi Jing had done a muscle strength measurement at the beginning, and there were some problems with Ye Han's muscle strength.

Moreover, cadmium poisoning not only damages joints and heart, but the first thing to invade is actually the kidneys. There are no symptoms caused by kidney damage, and I have never done any urine routine after being admitted to the hospital: "It seems that they will have to check for urine routine tomorrow, and heavy metal poisoning must also be checked..."

Qi Jing sighed, this "round check" was still effective.

Including viral myocarditis caused by influenza virus and drug-induced heart disease caused by drugs, he now has a third direction.

Judging from the clues in hand, the possibility of the first two is very low. Viral myocarditis starts rapidly and the influenza course is very long. It should not be like Ye Han now. The latter requires the existence of related drugs. But after searching for it, they did not gain much.

Of course, Qi Jing won't remove them immediately.

In nature, it is not just influenza that can cause viral myocarditis, coxsackie, parvox, adenovirus, rubella, EB, giant cells, etc. All of this is possible. The symptoms of chronic myocarditis are indeed mild, and it is normal not to detect them in normal times. The medicine is even more complicated. Maybe Ye Han put the medicine at home, but this trip did not bring it at all.

Compared with these two, poisoning of foreign items may be more reliable.

"By the way, have you seen these beads and hangers before?" Qi Jing asked.

"I've seen this several times." Yang Zesheng has never been interested in these things. "At first, when she was in love with her for only two months, she came to see me from the United States. I saw this string of beads, which looked quite beautiful. I also asked, and she said it was given to her by her senior sister."

"How long has it been?"

"It's more than a year ago...I forgot how long it took."

"How long have you been in love?" Qi Jing suddenly asked an irrelevant question, which made Yang Zesheng a little surprised, "What are you afraid of? I'm just gossiping, just ask, you were digging my old secret just now."

Yang Zesheng thought for a while and replied, "It's been two years."

"She is in the United States, you are in Australia." Qi Jing was quite surprised, "You are actually in a long-distance relationship."

"Yes, what's wrong?" Yang Zesheng didn't care much about this relationship. "I am studying in Australia and I can't live without it. When I was in love, I said yes and would live together after I graduated."

Qi Jing hummed softly, disagreed with this: "Now you have graduated, and you haven't seen you two live together."

Yang Zesheng was so embarrassed that he quickly retorted: "What I meant to live together is to end a long-distance relationship!"

"Okay, okay, I won't be kidding." Seeing that he was a little anxious, Qi Jing changed his question, "How do you meet normally?"

"Should she take a vacation, she can take paid leave for two months every year." Yang Zesheng said, "Otherwise, I can only wait for me to take a vacation, which will only take about one month a year. After all, what I research is special and I have always been very busy."

When Qi Jing heard this, he seemed to have thought of something and did not rush to say it. After finishing a little bit of thinking, he said, "Then you only met for two months a year?"

"Where is it?" Yang Zesheng shook his head, "I have to have a rest when she comes, otherwise what should I do when I come? It will take only more than a month to do it."

"...So that's how it is." Qi Jing couldn't help but ask, "You have lived separately this month?"

"yes."

Seeing that he was eager to speak but stopped, Yang Zesheng asked, "What's wrong? Is there any problem?"

"Oh, nothing." Qi Jing pretended to look at the beads in his hand and whispered, "You didn't ask what material it was or where I bought it, which made me very passive."

"It's just beads. Why do I ask this? What if she thinks I'm troublesome?"

"Forget it, this thing should not be difficult to check. I'll just call and ask my friend." Qi Jing sighed and picked up the keys again. "As for this ornament, it looks like a small gourd foundation, and the paint on it should be fine. Let's just treat it as an ordinary handicraft for the time being..."

Among the three things, he was concerned about the smell of this perfume. Only perfume can cover the whole body for a long time and is more likely to produce toxicity. However, Qi Jing lacks the knowledge of foreign perfumes and cannot recognize what the smell is, so he can only give up.

"It's getting late, let's finish the work."

“Have you found it?”

"It's okay, but..." Qi Jing shook his head, "The clues are a bit messy, I have to go back to the room and think about it. By the way, what time will the Xincai Super League be determined tomorrow?"

“Ten o’clock in the morning.”

"Oh, I got it."

Ye Han didn't have many things, and the room was not big, so the search work ended shortly after the beginning. On the contrary, it took even more time to restore the object to its original state. Qi Jing was too lazy to do such things, and Ye Han was not his girlfriend. After getting the exact time for color ultrasound, he patted his butt and returned to his room.

It was already eight o'clock when Yang Zesheng finished cleaning up the scene. The Japanese ward had already been cleared, and all family members had to leave. At this time, Lu Zishan also left the hospital and took the subway to return to Park Hyatt Hotel.

However, after going upstairs, she did not go back to her room No. 5003, but went to the 51st floor and knocked on Qi Jing's door.

"You're finally back, where's the phone card?"

"It's been changed back." Lu Zishan shook his cell phone, "Where are you here? How are you checking the room?"

"It's okay, I'm a little clue, but the specific details are not clear yet, so I need someone to help me." Qi Jing lay back on the bed and asked, "Have you seen a string of pink beads that Ye Han wore?"

"I haven't seen it before." Lu Zishan put down her bag and shook her head, "Pink beads? And pink jade?"

"That's not jade." Qi Jing gently rubbed his forehead, "I always feel it looks familiar. I must have seen it before. The name is right next to my mouth, and I can't call it."

"Does this bead have anything to do with her illness?"

"I think it will be a little bit related, but..." Qi Jing shook his head and asked again, "By the way, have you smelled tea-scented perfume before?"

"Tea flavor?"

"Actually, it can't be said to be a tea in the strict sense, it's quite similar." Qi Jing scratched his head, feeling that he had entered a dead end. "The taste of this tea is quite strange, I just don't know where it is strange."

"Oh, you've forced yourself too hard, so let's talk about it when you check it out tomorrow." Lu Zishan comforted, "When this matter is over, I have a troublesome customer here to ask you for help."

"Just hepatitis C last time?"

"Yes." Lu Zishan stretched and poured himself a glass of water, "Anyway, it's a strong woman."

"What did you say you're taking this job?" Qi Jing complained, then flipped out the communication list on the phone screen, "I talked to her last time, and the requirements are really high."

"It's boring to always do domestic medical disputes." Lu Zishan changed her clothes and hair, turned around and went into the bathroom, "You have a company, and you may have to cross-border in the future, and I have to transform as well."

"Okay, it's up to you."

Qi Jing listened to the sound of water in the shower, staring at a person in the address book and hesitated more and more. Although his face was thick enough, he could not always stare at someone to help him. He had to be able to cut leeks with a certain degree. If he injured the sheepskin or dig the roots of the leeks, it would be troublesome.

"Forget it, I'd better think of another way..."

Just as I said this secretly, a phone call suddenly came in, and the person was displayed on the call reminder.

Qi Jing knew that he wanted to take the path of sustainable development, but he couldn't stand others coming to him for free, so he quickly answered the phone: "Oh, Mr. Han, what gust of wind blows you?"

Li Han actually wrote this phone call from the master to ask for guilt, and he was slandering words and waiting to say it. He never thought that the other party would not give him a chance to speak, and he just greeted him: "I just said to you, I wanted to call you to chat with you, but I didn't expect you to call me..."

As the saying goes, don’t hit people with smiley faces.

Maybe because he stayed in Japan for too long, Qi Jing also learned this set of things, and the transition was very fast. After a few words made Li Han faint, he immediately entered his own topic: "Mr. Han, you are knowledgeable and knowledgeable. I am now facing a difficult problem, so I want to ask you."

"Uh, um, what's wrong?"

"You have handled so many major cases, you should have been exposed to perfume, right?"

"I have been in contact with it. Although I don't have it in the textbook, I still have to learn it when it's time to practice." Li Han felt something big, and hurriedly asked, "Aren't you in Japan? Have you encountered a case again? Why are you the same as Conan!"

"It's not a case." Qi Jing quickly denied, "There is a young patient with a bad heart."

"Oh, then what? Is there a problem with the perfume?"

"This is the first time I smell this perfume, and it has a faint tea smell."

"Tea? That should be a green fragrance." Li Han said, "Perfume is divided into six types according to the different materials of its manufacturing: flower fragrance, green fragrance, fruit fragrance, cypress, oriental fragrance and aldehyde fragrance."

“Where is the brand?”

"How can I know the brand? I'm not in Japan!"

Qi Jing was also helpless. After all, he was not around and could not distinguish it: "Then let me ask the other one, a string of pink beads, have you encountered it when you work?"

"What material is it? Gem?"
