When Chu Shi'an and An Shijin came out of the conference room, the last golden light on the horizon was just engulfed in darkness, the dim street lamps on the street were all lit up, and the various neon lights in the city were also shining one after another, and the nightlife was about to begin. The two walked side by side to the elevator, busy all day, both of them looked a little tired. Chu Shi'an frowned, put her hands in her pockets, her lips pursed slightly, there was a little deep thought in her dark and deep eyes, she spoke in a low voice, and she didn't know whether she was saying to An Shijin or talking to herself: "Almost all the in-service doctors have finished the trial, and they still haven't found any useful clues, and it seems that the case is now at an impasse again." An Shijin stood aside and nodded, and sighed softly: "It's better for me to comb through all the clues from the beginning again and see if there is anything missing." ”

"Hmm." Chu Shi'an replied casually, his slender fingertips against his chin, he lowered his head and didn't know what to think about, he still looked pensive, he had already arrived at the elevator entrance, his footsteps still didn't stop, and he was about to hit the elevator door that hadn't been opened yet. An Shijin, who was in the back, was stunned for a moment, and then when Chu Shi'an was about to collide, he grabbed her by the collar at the back of her neck and pulled it back: "Concentrate when you walk, look up at the front, big detective." The corners of An Shijin's lips rose slightly, and he smiled a little helplessly, and the person who was dragged back didn't seem to react, his clear eyes were blank, and he turned his head to look at An Shijin blankly.

"You look stupid right now." The smile on the corner of An Shijin's mouth was even stronger, and she couldn't help but reach out and poke Chu Shi'an's forehead, why did this person still look so stupid, and his usual indifferent and clever appearance was now half gone. "No, we're looking in the right direction, but it's possible that something was missing, but I can't remember it right now." The confusion in Chu Shi'an's eyes dissipated, but as if he hadn't heard An Shijin's words, he focused on talking about the case.

An Shijin frowned, and secretly rolled his eyes, feeling a little unhappy in his heart, it is estimated that there is no figure of her in the eyes of the person who fell into the case, even if he disappears now, this person will not find out. "Ding." The elevator door opened, An Shijin snorted lightly, shook his long hair, and walked in with his head held high and stepped on high heels. After pressing the floor, there were only the two of them in the elevator, Chu Shi'an didn't speak, An Shijin didn't speak, he held his chest and occasionally looked at Chu Shi'an, who had been lowering his head, sighed softly, and then looked up at the number of floors flashing above the elevator in a daze.

About two floors down, the elevator cracked open, and a tall, thin old man walked in with a cleaning cart loaded with cleaning tools and sundries. An Shijin hurriedly got out of the way, dodged to Chu Shi'an's side, and gave way to the old man. However, the corner of his eye swept to the old man's somewhat sluggish footsteps when he came in, An Shijin instantly remembered this old man he had seen, last time at the door of Mr. Tang's ward, the old man's foot was hit by the bottle thrown by Mr. Tang's son, she showed a smile that she thought was gentle and accosted the old man: "Uncle, it's you." You injured your foot last time, and it hasn't healed yet. The old man, who had been keeping his head down and holding the handle of the cart, heard An Shijin's polite question, and finally glanced at An Shijin lazily, there was no expression on his face full of ravines and wrinkles, and there was no other expression in his cloudy and dim eyes, but his Adam's apple moved, squeezed out a little voice from his throat, and responded in a low voice: "Hmm." Then he looked down at the cart and stopped looking up.

Originally, An Shijin also looked at the old man's age, and kindly wanted to ask a greeting or two, to see if there was anything that needed help, but who knew that she was also ignored so much, which made her a little embarrassed and depressed. So for a short time, people who have never been ignored have been ignored twice so openly and secretly. An Shijin lowered his head and coughed lightly for two sentences, not talking much, closing his eyes and recuperating. It's just that after she closed her eyes, the elevator suddenly shook, and she heard a thud, the sound of something landing. Then as soon as she opened her eyes, she saw Chu Shi'an squatting down, picking up a book that had just fallen from the old man's cart and fell at her feet.

The book was very shabby, the title and pattern on it were almost worn out, and it was impossible to see what it was. It's just that when Chu Shi'an picked it up, he accidentally opened a few pages, and out of the corner of his eye, he caught a glimpse of the book that seemed to be densely packed with red pens to make a lot of marks and notes, and before she could see it clearly, the calloused hand that had been old reached over and snatched the book over. The old man who had been keeping his head down and not saying a word finally looked down at Chu Shi'an: "Thank you." Before Chu Shi'an could say goodbye, the elevator door opened, and the old man pushed the car out without squinting.

"This old man looks very withdrawn." An Shijin whispered, looked at the old man's disappearing back, and then pulled Chu Shi'an, who was in a daze again, out of the elevator and towards the parking lot. Chu Shi'an nodded, was silent for a long time, and then spoke: "Sometimes when people get old, they become stubborn and incomprehensible, just like becoming an unreasonable child overnight, and will do a lot of things that seem incomprehensible to us. ”

An Shijin glanced at Chu Shi'an, and after listening to what she said, he joked with interest: "Your current behavior pattern is so incomprehensible, and when you get old, you will probably be a withdrawn and annoying old lady." Chu Shi'an's dark eyes sparkled in the dim parking lot, and then looked at An Shijin with a smile: "I'm a lonely and annoying old lady, what about you, an arrogant old lady with flowers, it doesn't sound very likable." An Shijin raised his chin and looked at Chu Shi'an playfully: "Admit it, you have always been jealous that I am more beautiful than you and more charming than you, even if I become an old lady who is about to die, I am more beautiful than you and more likable than you." ”

Chu Shi'an raised his eyebrows, smiled lightly, and then tilted his head slightly to look at the smiling and smug beautiful woman opposite, and his low and magnetic voice slowly sounded: "Don't you dare to be jealous, I still expect that a hundred years later, you, a beautiful and likable old lady, are willing to raise me, a lonely and unlikable wife." An Shijin's delicate and charming face suddenly bloomed with an extremely amorous smile, and the tall and concave body fell into Chu Shi'an's arms as if it were soft and boneless, hooking her neck with both hands, and exhaling like a lan: "So, are you asking my little assistant for support, big detective." ”

Chu Shi'an's expression on his face remained unchanged, he looked indifferently at the charming woman in front of him who was close to her and her eyelashes were about to poke her face, stretched out his hand and naturally hugged her waist, a smile flashed in his eyes, and he snorted softly: "Hmm." "It's really nerve-wracking, others are raising some pleasing and humorous little white faces, but you can tell me, you have an incomprehensible ice cube face all day long, how can I be willing to support you." An Shijin's fingertips gently stroked Chu Shi'an's chin, and the charm in those seductive eyes was about to flow out like spring water. Chu Shi'an only felt that his heart was disturbed by something in an instant, and the itch rushed straight to his brain, looking at the woman who was smiling like a fox in her arms, Chu Shi'an smiled evilly, leaned into An Shijin's ear, and said in a low voice: "Doesn't my self-taught bed kung fu still satisfy Miss An to be willing to support me." ”

The coquettish smile stiffened on her face, and a faint flush lingered on her fair face, An Shijin glared at Chu Shi'an with disgust, and pushed her away: "Stinky and shameless rascal." At the beginning, she was blind to think that the person in front of her was a serious and cold ice cube, this is obviously a bright pervert who is cold on the outside and complains on the inside, and she thought that she would be able to tease this person often in the future and look at her red-faced, but now the situation has turned over, and the person who blushes every time she is molested is herself. Sure enough, dogs that can bite people can't bark, and those who can hold ice cubes are sullen perverts.

Chu Shi'an looked at the person with a flushed and shy face in a happy mood, and smiled secretly in her heart, from the very beginning she figured out the character of the person in front of her, a paper tiger with teeth and claws, on the surface he looked frivolous, but in fact, he was very innocent inside, and every time she was anti-flirtatious, she blushed, but she didn't know it, she had to bump into it every time, but it was cute and tight.

An Shijin knew that she was molesting this broken jar now, so she stomped her foot and turned her head to leave. Chu Shi'an smiled in a low voice, turned his head and inadvertently caught a glimpse of a car parked on the side, and stopped when he was about to lift his footsteps. An Shijin walked a few steps forward, but he didn't hear Chu Shi'an's footsteps coming, and turned around suspiciously, and saw Chu Shi'an standing next to a black car and turning around twice. An Shijin walked up to Chu Shi'an and asked suspiciously, "What's wrong." Chu Shi'an frowned tightly, and she pointed to the butt of the car in front of her: "Did you see that sticker, did you feel familiar, where have you seen it?" An Shijin looked in the direction Chu Shi'an pointed, and on the trunk next to the license plate, there were a few black and red spider stickers: "It looks really familiar, it seems to have seen it somewhere, but I can't remember where I saw it." ”

"Do you remember a surgeon named Yang Shuo who was examined today?" Chu Shi'an took a deep breath, and his brows furrowed even tighter. As soon as Chu Shi'an reminded him like this, An Shijin thought about it, and her eyes widened with sudden realization: "There is a little spider doll hanging on his keychain, just like this, it seems that this car is his." Chu Shi'an nodded, and the expression on his face became solemn: "During the interrogation today, he said that he had been working for thirty hours in a row, and he had to drive home for an hour, and he had been in a hurry to go back. It stands to reason that he should have left by now, at least not before tomorrow. An Shijin bit his lip and looked solemn: "The person who should have left a long time ago hasn't left yet, is he just..."

"Either way, we must find him." Chu Shi'an took a deep breath, took An Shijin's hand and ran towards the road.

In the dark ward, the old man with a ventilator was lying quietly on the hospital bed, and the electrocardiogram on the side was beating slowly. Suddenly, there was a faint sound of footsteps outside the room, which was getting closer and closer, stopping at the door, and then the sound of the door being opened. A black shadow stretched by the corridor street lamp appeared at the door, silently and slowly approaching the unaware old man on the hospital bed, the white white coat and the tight mask he was wearing, his face could not be seen clearly in the dim room, the sound shadow stood in front of the ward for a while, and then slowly raised his hand, the gloved hand was holding a syringe, the needle was aimed at the syringe pump erected on the side, and the sharp and cold needle flashed a cold light in the dark.
