Nurse Yu came to the living room anxiously, as if she was about to be judged under the gaze of the crowd.

Jian Jing took the initiative to give up her seat, asked her to sit down, and handed her a cup of hot tea: "Don't be nervous, just tell the truth."

Nurse Yu nodded.

Jian Jing asked: "On the day of the incident, at 3:20 in the morning, the alarm on the monitoring device went off. When you woke up, what did you do?"

"I immediately gave the patient a cardiopulmonary resuscitation." Nurse Yu answered quickly.

Jian Jing: "How was the chairman's body at that time? Stiff? Cold?"

Nurse Yu tried to recall for a moment and apologized: "I was very nervous at that time and was always looking at the electrocardiogram. I didn't pay close attention to what you said."

"That is to say, if the body temperature was cold and the neck was slightly stiff, you wouldn't be able to detect it?"

Nurse Yu hesitated for a moment and said, "That should be the case. I performed the cardiac resuscitation through his clothes and didn't touch his skin much."

"Did he close his eyes at that time?"

"Yes."

Jian Jing said, "Let me explain. I have said before that rigor mortis will only appear 1-3 hours after death, and the body temperature is more subtle. Within 10 hours after death, it will drop by about 1°C every hour. Because the eyes are closed, the cornea is cloudy and it is difficult to judge in time."

Jiang Baiyan said, "So, the chairman didn't die at 3 o'clock?"

She corrected, "No, this can only prove that it is not impossible for the time of death to be slightly different."

"What's the meaning of this?" Jiang Lian asked.

"Don't be impatient." Jian Jing continued to ask, "Nurse Yu, you vaguely heard some movement in your half-asleep and half-awake state, right?"

Nurse Yu said cautiously, "I'm not sure, it seems to be the case."

"Then did you hear the sound of glass breaking?"

She thought about it carefully and shook her head, "It seems not."

"Okay, you can go back now." Jian Jing said, "Next, let's sort out everyone's testimony."

She flipped through her notebook and said slowly, "Jiang Ou entered the chairman's room at around 12:20, and then Jiang Xue entered at around 30 out of curiosity, and left in a hurry about 5 minutes later. At that time, Jiang Xue mistakenly thought that the chairman had died, and was very panicked and anxious, so she went to find Mrs. Jiang. Is that right?"

This was the result of the (tearing) meeting (X) two days ago, and it was temporarily unanimously confirmed by everyone.

"Okay, I want to ask you two, when you entered the room, did you find any broken glass and liquid on the floor?" Jian Jing asked.

Jiang Ou said, "I didn't see it."

Jiang Xue also said, "I didn't notice it, so I don't think so."

"But at around 3 o'clock, there were broken glass on the floor, right?" She asked for confirmation.

Jiang Baiyan nodded: "Yes, I remember there was broken glass on the floor, right next to the five-piece cabinet at the door."

Jian Jing smiled and said: "Given the relationship between Jiang Ou and Jiang Xue, I think that things they both deny should be more credible."

No one refuted.

"So, at least at 12:30, the medicine bottle had not been broken. In other words, someone else entered the room during the nearly three hours from 12:30 to 3:20." Jian Jing asked, "Who is this person? Is anyone willing to admit it?"

Still no one spoke.

"Okay, let's put this aside for now. I have another testimony here, saying that at about 12:30, when Jiang Xue entered the room, Jiang Lian was on the phone in the courtyard on the first floor. Is that true?"

Jiang Lian hesitated and nodded: "Yes, I had a phone call with my husband."

"Show me your video," she said.

Jiang Lian went upstairs to get the laptop and opened the video file. There was a clear recording time on it, starting at 12:50 and lasting until more than 3 o'clock in the morning. Both parties were arguing fiercely about something.

Jian Jing glanced at Jiang Lian. She looked relaxed, as if she thought she was no longer a suspect.

Looking at Jiang Qi again, he frowned slightly, as if he was uneasy and suspicious.

Jiang Yu was a little anxious and kept changing his posture.

Mrs. Jiang hugged Jiang Xue's shoulders, as if to support and comfort her.

"It seems that the matter is very clear." Jian Jing said, "The video confirmed my guess. You were the first person to enter the chairman's room."

Jiang Lian immediately retorted: "Nonsense, do you have evidence? Who saw me go in?"

Jian Jing smiled and stretched her body: "Indeed, what I am going to say next has basically no evidence. It is all my wishful guess, but - what's the harm in listening to it, right?"

Jiang Lian said coldly: "I don't want to waste time."

"You can choose not to listen, but you will." Jian Jing didn't take it as an offense, and said to herself, "At 9:45 the night before the incident, you had a conflict with your father. He might threaten to cancel your shares in the group, so after you left, you became more and more scared and decided to stop it."

Jiang Lian stood up suddenly, her lips trembling, her voice sharp: "What benefits did Jiang Baiyan give you? Why do you want to slander me like this?"

Jiang Baiyan leaned his head and sighed sadly: "It's been a few days, can't you see my status?"

"I didn't frame you. Of all people, you are the one in the biggest crisis."

Jian Jing analyzed slowly: "Jiang Qi had conflicts with his father because of his marriage, but that's over. Jiang Ou wanted shares in the water business - the dispute that Jiang Xue heard was you, right? - but the chairman was clear that he didn't intend to give it to him, so dying early would be disadvantageous to him, and he wouldn't have a chance to convince his father again.

"Only you, Jiangshui Group was originally going to be handed over to you, but your father didn't like your husband, but you were unwilling to give it up. Moreover, only the Jiangshui Group, which the chairman regards as his heart and soul, would allow him to change his will on his deathbed. "

She was very determined: "So, you knew in your heart that the chairman was going to change his will the next day, which would definitely be disadvantageous to you, and this was the company founded by your mother and him, and you were even more afraid that it would fall into the hands of Mrs. Jiang and her daughter, so

you had to find a way to stop it. "It just so happened that you knew that Dr. Tao prescribed morphine for him, and maybe explained the dosage problem to you. You kept it in mind and wanted to use this method to shut him up."

Jiang Xue couldn't wait to get up and shouted, "It was you."

"That's too early." Jiang Yu disagreed, "Even if you unplug the monitor as you said before, Jiang Xue would definitely find that the screen was not lit when she went in."

"Be patient." Jian Jingwen did not move, and continued, "You did it, but you regretted it, right?"

Jiang Lian pursed her lips, her face pale, but she said nothing.

"Did you inject one or two? Anyway, not long after, you regretted it, stopped, left in a hurry, and called your husband in the yard, saying that you were possessed by the devil, your father was so good to you, raised you, and cultivated you, but you wanted to kill him. But the matter was done, and you were lucky, thinking that your father would be fine, and went back to your room to pretend that nothing happened."

The living room was silent, and everyone had different expressions.

Jian Jing smiled slightly and slowly revealed the rest: "The second one is Jiang Ou. I guess you didn't go to him to discuss things, but to get something - a mobile phone or a camera?"

Jiang Ou closed his mouth tightly, as quiet as a clam.

"Why did you do this? Because you are unsure. Jiang Lian works in the group, and the content of the will is probably related to this. Jiang Qi established the communication, so it should also be his. Only you have never done anything. How much the chairman gives you depends on luck, and your competitors are Jiang Baiyan, Jiang Xue and Mrs. Jiang. There is too much uncertainty."

As Jian Jing said to Jiang Baiyan before, the key to reasoning in this case lies in everyone's psychological state.

She carefully analyzed Jiang Ou's psychological motivation: "So, in order to take the initiative, you used a trick to install a camera in your father's bedroom and eavesdrop on his conversations with others."

Jiang Xue and her daughter stared at him coldly.

"But you saw a terrible thing - your eldest sister was murdering your father." Jian Jing said, "You must have been frightened after watching the video, but the relationship between you three siblings is very close. Your first reaction was to protect your sister, but with your ability, you were not enough to handle this matter, so you had to find Jiang Qi."

Jiang Ou said: "Whatever you say, I don't admit it anyway."

Jian Jing was immersed in the most pleasant moment of investigation, and waved her hand leniently, ignoring him: "Okay, the second one is over, let's talk about the third person, Jiang Xue."

She widened her eyes: "What does it have to do with me?"

"Of course." Jian Jing curled her lips, "When you entered the room, the chairman must have felt a little uncomfortable and looked like he was about to die. And you have always been very brave, and the chairman dotes on you very much. Maybe you wanted to get closer to see if he was really going to die, or maybe you knew about the safe and wanted to open it to take a peek..."

Jiang Xue's face flushed suddenly.

"Then, something you didn't expect happened - the chairman woke up." Jian Jing gave the answer, and was satisfied to see the other people's faces change.

She looked like a child who had successfully played a prank, and added with a smile: "Of course, it may also be that he looked awake. In any case, you were scared and ran away."

The reason why Jiang Xue left in a panic is a key to this case.

Modifying the will is disadvantageous to Jiang Lian, but beneficial to them. Therefore, on the night of the incident, Jiang Xue definitely did not intend to kill when she entered the room.

Why did she panic?

It is possible that the chairman was dying, but this is inconsistent with the time of death. Moreover, it makes no sense for Jiang Xue not to wake up Nurse Yu and rescue her father immediately.

She dared not speak out, proving that the situation has changed drastically.

The only person who can cause Jiang Xue's situation to completely change is the chairman.

"What will happen if my father sees me stealing a will, or misunderstands that I have committed murder?" Jian Jing vividly describes Jiang Xue's psychology, "The answer is undoubtedly, I will lose my inheritance rights. You immediately found your mother and told her the whole story - Mrs. Jiang, you are the next one."

Mrs. Jiang looked indifferent.

"You know very well that you can't get much from the chairman, so you have to keep your daughter's inheritance rights no matter what. For this, you don't hesitate to kill people."

Jian Jing's speech speed gradually became faster: "You arrived at the crime scene around 1 o'clock - actually, I doubt it, Jiang Lian, did you really see her? Not necessarily, she went downstairs from your room and it seemed that she didn't pass by - Jiang Qi, you guessed it, right?"

Jiang Qi glanced at her, neither admitting nor denying.

"Mrs. Jiang, when you entered the scene, was the chairman awake? Or was he unconscious?" Jian Jing asked the question, but she didn't need to answer it. She said to herself, "It doesn't matter. You have to do something, but you are an accountant and don't understand medical instruments. If you make a mistake and send out an alarm, waking up Nurse Yu, things will be very bad. The simplest and most effective way is to cut off the power supply to the room."

She waved her hands: "That's it, the oxygen tube and the monitoring device are useless. You know he will definitely die tonight, and my daughter's inheritance rights are saved."

The scene was silent.

"The last one, Jiang Qi. You know what your sister has done, so of course you have to cover up for her, and the best way is to frame the enemy and make him lose the inheritance right. In this way, no matter who of you three siblings holds the shares, it will not be considered as a betrayal to your mother."

Jian Jing looked at Jiang Qi: "You have made an internal system for Jiangshui Group, and Mrs. Jiang has worked in the group. Now all companies need to input fingerprints, and that's how you got her right index finger fingerprint - there is only this one fingerprint, otherwise it would be more perfect with the thumb - and then, you used a 3D printer to print out the fingerprint, entered my father's room, opened the safe, and left her fingerprint.

"I think, if I hadn't found the safe, you would have guided Lawyer Li to find it, right?"

Jiang Qi had to speak: "Ms. Jian, you are very smart, I underestimated you. "It's not time to praise me yet. "

Jian Jing paused, "You should have restored the power supply, so you arrived at the scene after the first alarm, but there is still a loophole here."

She looked around at everyone and smiled: "Who broke the medicine bottle?"
