I saw the medicine apprentice bring a bucket of water from the inner hall, and before Yan Qingyu could give an order, he splashed it at Doctor Zhao without saying a word.

Doctor Zhao was woken up coldly, opened his eyes, and saw Yan Qingyu, he screamed in fright, "I said, I will say everything, say everything." ”

Yan Qingyu walked to the stool, shook the hem of his clothes and sat down, crossed Erlang's legs, and spat lightly as if nothing happened: "Say it." ”

An Wanqing hid the dagger in her cuff, settled down, and turned her head to look at Zhao Yan.

Nangong Qi glared at Yan Qingyu fiercely, and also turned his head to look at Zhao Yan.

At this moment, Zhao Yan was tortured by Yan Qingyu, he was wet, his thighs and left hand were bloody, he was half-paralyzed on the ground, and said with a painful face: "Five days ago, a masked man woke me up from my sleep, and he threatened me with my wife's life, saying that he wanted to help him kill four people......"

The three of them were surprised.

Four people? Naturally, the murderer did not kill according to the five elements.

"And then?" Nangong Qi urged.

Zhao Yan collapsed on the ground and sighed lightly, "He used my wife as a threat, and I had to obey his arrangement." That night, he threatened me not to report to the police or he would kill my wife, and in order to control me, he took my wife, along with the books of my medical practice that I had kept for many years......"

"Books?" Nangong Qi frowned, "What account book?" ”

"In our line of work, every time we treat a patient, we will make detailed records, after all, we are doctors, and in case something happens, there is a basis for it. I have to keep a daily record of what medicine the patient takes, what the symptoms are, and when they come to the doctor. Zhao Yan explained.

"In other words, the murderer chose four patients from your account book as the targets of his murder." An Wan Qingdao.

Zhao Yan nodded sadly.

"Do you know what the murderer's purpose was? You can't find four people to kill for no reason, right? An Wanqing frowned, feeling a little depressed, "If you say that Gongzi has offended someone this Tuesday, it is credible." However, this Miss Li has been sick since she was a child and stays at home, so she must have no enemies. ”

"Obviously, the murderer's purpose is not revenge at all!" Yan Qingyu spoke.

"The night before, he asked me to help him kill the second son of Zhou Shangshu's mansion, and ordered me to help him kill Miss Li at noon today, after I killed the second son, I didn't want to cooperate with him anymore, he had to let me go to the Li Mansion to lure Miss Li's personal maid away on the grounds of follow-up, and he did it himself."

Speaking of this, Zhao Yan sighed bitterly, and pleaded with a pleading face: "Killing people pays for life, I know, I only ask the Overseer to save my wife." ”

"Ben asks you, have you ever seen a murderer?" Yan Qingyu asked.

Zhao Yan shook his head, "He is masked, but looking at his appearance and listening to his voice, he looks like he is in his forties." ”

"Has he ever come to you since?" Nangong Qi asked.

Zhao Yan shook his head, "After I left the Li Mansion, I went back to the Jishi Medicine Hall in fright, and I never dared to go out again." ”

"In other words, you don't even know why the killer killed these four people? I don't know, who will the murderer kill next? Nangong Qi frowned, it seems that this case is a bit tricky.

Zhao Yan nodded, "I know, that's all." ”

After speaking, Zhao Yan seemed to think of something, and recalled: "By the way, I remember that he seemed to have said that he only needed to kill four people, and if no one cracked the case, it would become a mystery for the ages." Even if he cracks it and catches him, he will also win. He said he deliberately left clues and whether he was caught, or not, he won. ”

"What a mess, this person is probably a perverted murderer!" Nangong Qi snorted coldly.

"Is there a second book?" Yan Qingyu frowned and asked.

Zhao Yan nodded again and again in fright, "When the patient comes to see the doctor, the medicine apprentice will record the patient's condition." At night, I always picked up the lamp and re-transcribed it. ”

"Bring another book, and the governor will take it with him." Yan Qingyu ordered.

When the medicine man heard this, he hurriedly got up and went to get the account book.

"The killer did leave clues. The first case, water and gall, there is gold, wood, water and fire. The second case, fire, heart, knots and threads......" An Wanqing took a deep breath and frowned: "These are clues." ”

"However, he wants to kill four people, and now there are not enough clues, and we can't catch him at all." Nangong Qi frowned, snorted lightly, and sighed helplessly, "This murderer is heinous, you can't wait for him to kill four people before solving his mystery." ”

"Dare to openly provoke the Imperial Jin Army, if this governor does not catch this person, he is not worthy of being the overseer of the Imperial Jin Army." Yan Qingyu clenched his fists, his green muscles burst out, and he gritted his teeth.

Nangong Qi frowned and glanced at him.

"The Overseer sees it too?" An Wanqing turned her head to look at Yan Qingyu.

Heart, the famous and unfazed Lord of the Imperial Jin Army who can provoke is so angry, this murderer can be regarded as having some ability.

"You can tell if Ben Du is dumber than you?" Yan Qingyu raised her eyebrows and looked at her, looking angry and unpaid.

"See what?" Nangong Qi asked.

"This case is complicated, and it will definitely alarm the Imperial Jin Army. The murderer killed people indiscriminately, and it was clear that he was targeting the Imperial Jin Army. If the Imperial Jin Army can't solve the case, its prestige in Kyoto will naturally be sharply reduced. ”

Speaking of this, An Wanqing frowned and shook her head in confusion, "It's just that there is one point, I don't understand, why would the murderer think that even if he was caught, he would win?" ”

An Wanqing was strange in her heart, and she couldn't figure it out.

It wasn't just her who was also puzzled, Yan Qingyu was also a little puzzled.

Yan Qingyu's pupils sank deeper and deeper, and he had a vague sense of foreboding, always feeling that a cloud of mist was slowly shrouded, and a large net was rushing towards him......

Seeing that Zhao Yan couldn't ask anything, the three of them had no choice but to go home.

Inside the carriage, the three of them were speechless, and their moods were different, but they were all suppressed by an inexplicable sense of tension.

Back at Zhou Shangshu's Mansion, the three of them sat together and discussed the case, but they always felt that something was missing, and the clues could not be connected.

The next day, as soon as the sky was bright, the three of them all came to the pavilion in the backyard.

"Morning, Governor." An Wanqing had no choice, so she could only give Yan Qingyu some face.

Nangong Qi didn't have to give anyone face, "So early, can't you sleep?" ”

Yan Qingyu would not give him face, and looked arrogant, "This governor has a habit of getting up early. ”

An Wanqing glanced at him secretly, speechless in her heart. Obviously worried that he wouldn't be able to sleep on the case, and he would still want to save face. Today is the deadline, and if the case is not solved, I am afraid it will be ......

"Overseer, there have been four murders, and now there have been two, if there is a third murder, you can ......"

Before An Wanqing could speak, he saw Mo Ting hurriedly running over, "Overseer, just now, I received a report......

The three of them were all startled, and at the same time turned their heads to look at Mo Ting, who was panting.

Mo Ting breathed a sigh of relief, and without waiting for Yan Qingyu to speak, he frowned and said hurriedly: "Master, Liu Yuanwai, who is located on Donghua Street, died in his room, and the deceased is extremely similar to the death of Gongzi and Miss Li of the Li family, it must be a serial murder case." ”
