At a quarter past ten o'clock in the evening, Luo woke up and came to the outpatient building of the People's Hospital. He didn't go straight into the building, but walked around the outpatient building.

Luo woke up and listed Tong Susu as the first suspect, and the purpose of his coming here was to find a method and path for Tong Susu to be out of everyone's sight for one to two hours, and to reach the scene of the crime quickly and covertly. As for what method Tong Susu used to kill Cao Leping, it would not be too late to make an inference after Zhang Xiaoling had completed the autopsy.

Luo Xing had his own speculation in his heart: Tong Susu had worked in the surgical emergency room for many years and was used to seeing life and death. This kind of tempering between life and death will make Tong Susu have a strong nerve and calmness that ordinary people can hardly achieve.

With her experience and knowledge, if she wants to kill Cao Leping quietly, it should only be a matter of choice of means, and there will be no deviation. And in the whole process of implementing the case, she only had two links: how to hide her whereabouts and how to go back and forth to the scene. So you have to focus your limited time on these two aspects, looking for methods and validating hypotheses.

It was not yet late at night, and there were still crowds of people gathering outside the outpatient building. Luo woke up, found a long row of lounge chairs in the corner at the edge of the small square, sat down, lit a cigarette, and quietly observed. The entrance to the outpatient building has a large awning, which is brightly lit and equipped with cameras. There are also a lot of people coming and going, and this is not a suitable place for hidden access.

In the center of the small square there is a small flower bed, around which several paths lead in all directions. The outpatient building is located on the west side of the entire people's hospital, facing south from the north to the north, and is not a separate building. The rear of the building is connected to the inpatient department on the north side by an enclosed flyover on the second floor, while the first floor is not connected.

The building of the inpatient department is adjacent to Xiwai Street, with only a fence in between. This section of Xiwai Avenue is a two-way, four-lane closed section, and there is no overpass or underpass between it and the railway bureau compound on the north side of the road, making it almost impossible to pass through. The nearest overpass and underpass to the west side of the clinic building are 200 meters further west.

Luo woke up and lit another cigarette and took a few big puffs. According to the scene described in Liu Erzhuang's interrogation transcript, when Liu Erzhuang entered the scene, the other suspect had already completed the procedure for the murder of Cao Leping and was arranging the traces of the scene that he had already planned. Liu Erzhuang's sudden intrusion caused the arrangement process to be unexpectedly terminated. But this suspect was in danger, and faked another more perfect murder scene under the pretense of Liu Erzhuang's hand.

According to Liu Erzhuang's break-in time (3 o'clock in the morning), the first suspect at the scene has stayed at the scene for at least 30 minutes to complete the entire murder process. If the suspect was Tong Susu, then she should have left the hospital around 2 a.m. and returned to the hospital before 4 a.m., and then appeared in the public eye as usual. It will take no more than 30 minutes each way.

Luo woke up and walked around in the direction of Tong Susu's dormitory. Tong Susu's dormitory is located at the southernmost end of the hospital, in the opposite direction to the crime scene. This distance is even more impossible, could it be that she has used other means of transportation to shorten the time?

Luo woke up and walked back while thinking, the complex environment of the hospital is indeed difficult to achieve a long period of silent concealment. If his previous inference is true, and Shao Guowei finds Tong Susu on the return trip and threatens him, then Tong Susu should also pass through the West Gate on the return trip. Could it be that Tong Susu took a different path when he went to the scene of the crime than when he returned to the hospital? This is a risky plan, and the unfamiliar environment will multiply the risk of accidents.

What reason or method did Tong Susu have to enter the scene of the crime from the east side? Not to mention whether Tong Susu would act like this, but he already felt bold enough to imagine this. After thinking about it for a while, Luo woke up and decided to take a look in the direction of the east gate.

The east gate is the main entrance of the People's Hospital, close to the West Second Ring Road. Luo woke up and counted the time as he walked, and it seemed that his judgment was wrong. It took Luo twenty minutes to wake up just from the outpatient building to the door of the east gate, which was the result of his calculation after speeding up his cadence. If you go further north to Xiwai Street and cross the road before entering the crime scene, it will take about 30 minutes even if there is a bicycle or other means of transportation.

Although this time consumption is still within the range of the highest estimate, it can be basically ruled out. Because killing people is not going to the free market to buy groceries. After arriving at the site, it is necessary to make various preliminary preparations such as stabilizing emotions, observing the situation, and recovering physical strength, in order to reduce the chance of accidents during the implementation process. Therefore, no matter how tedious the preparation work is, it is necessary to prepare in advance.

Luo woke up and walked back with some disappointment, and the time was close to twelve o'clock in the night. The number of pedestrians on the road has decreased significantly. Nearly two-thirds of the way back, Luo woke up to find that from a small forest on the north side of the road, a young man and a woman had emerged, one after the other, who were supposed to be lovers. And what they traversed was an inconspicuous path, a path that was tread by only one person.

Luo woke up and walked towards the dark path. It is a very dense forest, planted with some pine and cypress trees, and some walnut and date trees in between. There are a few low shrubs here and there, which are quite dark. After turning over a small gentle slope that was not too steep, Luo's eyes lit up, and the corners of his mouth hooked a trace of clear arc.

At about one o'clock in the morning, Luo woke up and pretended to be haggard and came to the emergency registration office in the outpatient building, "Doctor, I have a little hypoglycemia. I had a bit of a heat stroke at noon today. See if you can hang a hanging bottle for me and inject some glucose water or saline. I felt bad. Luo woke up in Mandarin with a southern accent and dressed himself in dust.

"No, what's the fight? Still sugar water? We're here for an emergency, and you're wasting our resources and time. Just go back and eat some sugar and get some sleep. The eldest sister in charge of registration smashed Luo Xing's little plan with righteousness and solemnity.

"You see that my family is out of town, and the accommodation on the construction site is not very good. I'm here for a little bit of work, and by the way, it's time to rest. It won't take much of your space, just add a little money. You're just thinking I'm unconscious, or I'm going to lay you down now?" Luo woke up and squeezed out a smile that he thought was charming, and began to play the scoundrel. (This book has been renamed "The Last Logic" and signed and released on Iron and Blood, I hope everyone will cheer you on then.) ）

Twenty minutes later, Luo woke up with a drip bottle in one hand and swayed all the way to the observation room of the emergency department. There weren't many people in the observation room. Luo woke up and found a place near the door, hung the drip bottle on the stand and slowed down the speed of the drip, and began his observation with half-squinted eyes.

At this time, there was no urgent situation to deal with in the emergency room, and it seemed very quiet. There were only two young nurses in the disposal room talking in low voices. I didn't see Tong Susu. Luo woke up and simply began to pretend to sleep and waited patiently, and after a while, he really fell asleep.

A rush of footsteps and muffled whirring woke Luo from his slumber. When I looked at my watch, it was already two and ten o'clock, and I slept for forty minutes before I knew it. What a delay. Luo woke up and stood up, and saw four or five people pushing a stretcher cart and walking briskly through the corridor and into the emergency treatment room under the guidance of a small nurse. Listening to the words and talking to the meaning of this is a person injured in a traffic accident with skin trauma and internal bleeding.

At this time, a pretty figure appeared in Luo's awakened sight. Tong Susu calmly pushed the door out of a nurse's rest room at the north end of the corridor with a standing "idler stops". Dressed in a light blue nurse's uniform and a white nurse's hat, her slender figure of about 1.65 meters looks outstanding. Luo's awakened gaze was always on Tong Susu's feet.

Tong Susu walked quickly to the injured person's stretcher cart, glanced at a few people, and then motioned for the little nurse to help. The victim had symptoms of internal bleeding, and blood foamed from his mouth from time to time. To transfer the injured person from the stretcher truck to the disposal table, a high level of skill is required to avoid secondary injury to the injured person. The little nurse didn't dare to move, and several friends of the injured around her also looked nervous, but Tong Susu's glance seemed to have magical magic to make this small restlessness instantly calm down.

Tong Susu came to the side of the injured person's head and examined it for a few seconds, then nodded slightly to the little nurse, and then put her hands under the injured person's body. One hand supported the neck of the injured person and supported the head very skillfully, and the other hand supported the sacroiliac joint of the injured person near the position of the upper spine. In the tacit cooperation of the little nurse holding the leg of the wounded, the injured person was quickly and smoothly transferred to the operating table. All in one go, clean and beautiful.

Luo's eyes lit up instantly.
