Wan Gui's house was empty, and no jewelry was found in his room, and when he inquired around, the neighbors said that he had not returned overnight, and no one knew where he had gone, and there was no news from the east and west gates.

When Nie Xiaohu was depressed, Shi Yuning suddenly slapped his head, "Tiger Head, this Wangui is a good friend of Yan Yufeng, and he often goes to her, so I also know a little bit about this person, this person has two major hobbies, one is women, and the other is..."

"Gambling!" , Nie Xiaohu blurted out.

"A tiger head is a tiger head!" , Shi Yuning raised his thumb.

In the largest providence gambling house in the county, the sound of pushing cards, the sound of dice, shouting five and six voices are mixed together, crying and laughing one after another, and the people who have lost red eyes are sweating here to their heart's content, and send a lot of their hard-earned money into the banker's pocket without realizing it.

In a corner of the noisy casino, there is an iron door, at this time the iron door is open, inside is a counter, separated from the outside by an iron fence, an old man in the counter is holding a pair of jade bracelets in a careful look, outside the iron fence a middle-aged man is carrying a burden on his shoulders, nervously looking at the old man in the counter.

"The best mutton fat white jade, the head of the water is very sufficient, but there are slight flaws", the old man nodded, muttering to himself.

"How, how much is it worth?" , the voice of the man carrying the burden was full of anticipation.

"Three hundred and fifty taels, I'll pay the most here," said the old man, putting the jade bracelet back on the counter.

"Okay, okay! Take the money! The middle-aged man's eyes lit up and he said excitedly.

"I'll give you a thousand taels!" , a cold drink came from behind the middle-aged man.

"Really?!" , The middle-aged man turned around happily, and when he saw the person who spoke, the expression on his face immediately changed from joy to consternation, and then to frustration, the whole person wilted, and with a "snap", the burden on his shoulders slipped to the floor.

After handing over Wangui and the stolen jewels to Sun Bingying, it was already three or four o'clock in the afternoon, Nie Xiaohu first arranged for Shi Yuning to go to investigate Qiu Shi's recent situation, and then rushed to the home of Dr. Gong Changye non-stop.

"Doctor Gong, Qiu Hua's illness has been treated by you for a long time?" In a small pharmacy, Nie Xiaohu sat face to face with a long-haired old man and asked.

"It's old decay," Miyano replied with a nod.

"Tell us what you know!"

"Hmm", Gong Changye stroked the long beard under his chin, and said slowly: "I have known Qiu Hua's father for a long time, Qiu Hua's child was raised by me watching her, this child has suffered from asthma since he was a child, and as he grew older, his condition did not improve, I checked the medical books and studied a lot of prescriptions, but they did not have much curative effect, I am ashamed of the old decay!" Gong Changye shook his head with a guilty face.

"Then what is Qiu Hua's recent condition, has it reached the point of fatality?"

"Recently, I have been to see Qiu Hua a few times, although it is still the same, but the condition is still very stable, it should not be, but asthma is also difficult to talk about, if it is suddenly stimulated by the outside world, the condition worsens, and the sudden attack may not be."

"Outside stimuli? What do you mean? ”

"For example, smoke, hot and cold temperature changes, or inhalation of odors and so on can irritate the patient."

"But...", Miyano seems to have remembered something?

"But what?" , Nie Xiaohu's eyes lit up.

"On the night when Qiu Hua had sudden asthma, Qiu Shi knocked on my door in the middle of the night, saying that Qiu Hua was sick and asked me to go and see, but when I arrived, it was already late, and Qiu Hua had already died, but Qiu Hua's situation at that time made me feel a little puzzled."

"Oh? Tell me about it. ”

"Hmm", Gong Changye nodded, frowned and said, "Generally speaking, people who die from asthma should have symptoms such as purple face, hands and feet due to suffocation, protruding eyes, and open mouth, although Qiu Hua also meets this kind of symptoms, but what makes me feel strange is that Qiu Hua's mouth is tightly closed, and I found two white silk threads between Qiu Hua's teeth, very similar to those on a towel, as if they had bitten a towel or something like that before he died, In addition, I found blood stains in the nails of Qiu Hua's hands and ten fingers, which really puzzled me. Gong Nagano shook his head as he spoke.

"I see."

Nie Xiaohu nodded, frowned and thought about it, and suddenly seemed to think of something, muttered for a while, and then asked, "Doctor Gong, did you just say that you and Qiu Hua's father are old acquaintances?" ”

"Well, that's good."

"Then do you know any family heirlooms of the Qiu family, such as gems or something?" , Nie Xiaohu asked, looking at Gong Changye with expectant eyes.

"How do you know?" , Gong Changye was stunned for a moment and asked rhetorically.

Hearing this question, the question in Nie Xiaohu's heart was settled, and he couldn't help but smile with satisfaction, "I'm just hearsay, I just want to ask you for verification." ”

"Yes, the Qiu family has a treasure", Gong Changye nodded and said, "It is a rare gem, called a cat's eye, it is expensive, it is handed down by the ancestors of the Qiu family, Qiu Hua's father has never mentioned this matter to outsiders, and there are only a few people who know about it, but whether this gem was passed on to Qiu Hua or Qiu Shi, this old man does not know." ”

"Thank you, Doctor Gong!" , Nie Xiaohu has already got the answer he wants, and he is about to leave.

"Nie Zhutou is not polite, if he is old, it is also an honor for him to be able to provide a little help to Nie Zhutou!" , Miyano said with a smile.

"Tiger head, find out!" At this time, Shi Yuning strode in.

"Qiu Shi opened a small shop, doing a timber business, and the original business was quite passable, but half a year ago he had a serious illness, I heard that there is a medicinal material called A Hibiscus in the medicine, Qiu Shi was addicted to this A Hibiscus after he got well, and he had to smoke it every few days, and this A Hibiscus was expensive, and Qiu Shi's financial resources couldn't afford it at all, just a month ago, he actually sold the store, in order to buy A Hibiscus, it was really unpredictable."

"Fleur? What is this? Nie Xiaohu frowned.

"Why does it sound so drug-like?" , Nie Xiaohu thought to himself.

"Hibiscus is a kind of medicinal material, which was introduced from Persia, with analgesic, detoxification, antidiarrheal and other curative effects, and is commonly known as the 'universal antidote', but it can only be used in small amounts each time, and the patient is very addicted to the large amount, and it is extremely difficult to quit, and long-term smoking of Hibiscus is extremely harmful to the body", said Miyanagano with his eyes slightly closed.

"Isn't this just a drug? I rub! I didn't think there would be drugs in the Tang Dynasty! Nie Xiaohu's eyes lit up, and he stood up suddenly, his eyes flashing with excitement.

"Little stone!"

"Tiger Head!"

"You rush home now, grab Qiu Hua's painting and your son's wooden sword, and then rush to Qiu Hua's house to fight with us, and we'll go over now!"

"Understood!" , Shi Yuning agreed, frowned, and left with a puzzled face.

Under the guidance of Gong Changye, Nie Xiaohu and others came to the door of the small courtyard where Qiu Hua and Qiu Shi's sisters and brothers lived, the courtyard door was open, and the courtyard was like planning to plant trees, large and small soil pits were everywhere, and everyone just arrived in front of the courtyard gate, and they heard "Oh!" from behind the house. Poop! Voice.

Nie Xiaohu smiled slightly, and led everyone around the small building, and saw that in the southeast corner of the backyard, a person was holding a big hammer, and he was smashing a stone on the ground that was the size of a small table.

"What are you doing here?" , Nie Xiaohu asked with a smile.

Qiu Shi, who was concentrating on smashing the stone, was startled by this sudden question, and hurriedly stopped and turned his head to look.

"Original... It turned out to be an official, looking for me to have... Can I help you? Qiu Shi wiped the sweat from his neck, nodded and asked with a smile.

"You smashed this big rock so hard, it can't be that there is some treasure hidden in it, right?" , Nie Xiaohu smiled mockingly.

"Which... What's the treasure there, I just see it in the way and want to smash it", Qiu Shi put down the hammer in his hand, and came to Nie Xiaohu while wiping his hands on the hem of his clothes, although he had a smile on his face, he smiled extremely unnaturally.

"Don't bother, the gem is not in it", Nie Xiaohu said lightly.

"How do you know?" , Qiu Shi blurted out reflexively, and then closed his mouth, a trace of panic flashed in his eyes.

At this time, Mao Guangjian suddenly turned around for some reason and ran towards the room.

Nie Xiaohu sneered and said lightly, "Say it." ”

"Say... Say what? Qiu Shishi laughed twice.

"Tell me how you killed your sister!" , Nie Xiaohu said coldly.

"What? This... This? Qiu Shi took several steps back one after another, sweating faintly on his forehead.

"Tiger head, chair!" At this time, Mao Guangjian ran back again, carrying a chair in his hand and placing it behind Nie Xiaohu.

Nie Xiaohu nodded with satisfaction, and looked at Mao Guangjian.

"Where does this start, Lord Official, you can't just talk about it! As we all know, my sister died of a violent illness! Qiu Shi's voice was full of panic.

"Tang Yibin!"
