No matter what your identity is now, what should be investigated must be investigated.

Li Yang found the doctor, and it was a coincidence that he was about to leave. At this time, he was still the same as he had just rushed out of the fire, his face full of gray and mess.

Seeing Li Yang, he nodded slightly and wanted to leave.

Li Yang grabbed him: "Doctor, wait a moment, I have something to ask you."

The doctor looked at him in surprise: "What's wrong? I think you've followed the police officer, why do you have something to ask?"

"You just went with him to check the scene. The specific situation must be the one you know the most." Li Yang said with a smile.

The doctor held up his glasses and looked at Li Yang strangely: "What are you going to do? Isn't it better to leave this matter to the police? Ordinary people should stay out of it."

"I'm just a little curious. Think about it, if such a powerful fire is just an accident, of course there is nothing to pay attention to, but, do you know?" Li Yang hugged the doctor and deliberately lowered his voice and said, "I just went to see the scene with Officer Feng. Someone deliberately set it to an abnormal state in the firefighting facility, which made it impossible for you to put out the fire as soon as possible!"

"What?!" The doctor looked at Li Yang in shock. Li Yang quickly covered his mouth and pulled him aside.

"I promised the police not to disclose this matter casually. Doctor, you have to keep it a secret for me! Otherwise I will enter the bureau!" Li Yang hugged the doctor tightly, and whispered in a low voice: "We went to the back to see the firefighting facilities. Someone deliberately turned off the fire water pump and turned on the fire hydrant in advance to release the water pressure, which caused the people on the scene to be unable to provide effective rescue when the fire broke out! So now, it is 100% certain that someone deliberately set fire!"

"Deliberately arson!" The doctor looked at Li Yang in shock, "What is he trying to do? Revenge on society?"

Li Yang shook his head: "How can anyone retaliate against society? Thinking about closing the firefighting facilities in advance to make it invalid? If you think of this, it means that he has made a detailed plan! Apart from being an anti-society similar to the clown (DC), there is only one explanation... He is trying to kill people!"

"In the ward where the oxygen cylinder exploded, there was only one patient at that time, that was Teacher Wang! So, that Teacher Wang was very likely to be the target of the murderer!"

"You think about it now. Is there anything special about Teacher Wang's specific information?"

"Uh..." The doctor looked at Li Yang, "Even if I remember something, I should tell the police..."

"You just need to tell them again! I'm just curious, otherwise I wouldn't analyze it in front of the police. Look, isn't that Director Feng interested me? He also took me to the crime scene!" Li Yang said with a smile, "Don't worry, it's purely a personal hobby. Director Feng also agreed to go back and share the information with me."

"Okay." The doctor looked at Li Yang and chose to believe in this man who was brave enough to rush into the fire. "Wait for me to wash up and change my clothes. Anyway, the hospital's work is not done at the moment, and I'm idle."

"Let's go, let's go together." Li Yang patted his pocket and said generously, "I'll invite you to take a shower!"

Li Yang pulled the doctor to a nearby leisure place and rushed in the bathhouse.

The doctor was named Liang Ke. He had been working in this hospital for several years, but he was still a newcomer in the hospital. When he encountered this, he did not recover for a while. However, when Li Yang took him to relax for a while, the urge to find the truth was also ignited in his heart!

"That teacher Wang, whose full name is Wang Demen." Liang Ke sat opposite Liyang, holding the steaming teacup in front of him, and said while recalling, "He seems to be a teacher from No. 1 Middle School and an old teacher. I heard that he has taught books that have been teaching for more than 30 years."

"Teaching for so many years?" Li Yang opened his eyes wide, "That qualification is really old enough. Such an old teacher should be respected, how could anyone want to harm him?"

"Yes, an old teacher." Liang Ke said. Suddenly, he seemed to think of something, but just sighed, but didn't continue.

"What's wrong? What did you think of?" Li Yang felt something was wrong and asked quickly.

"Maybe I thought too much... Maybe I made a mistake..." Liang Ke raised his head and looked at Li Yang and said, "This old professor is probably not a respected person..."

"When he was just admitted to the hospital, his health was not very good, his digestive system was inflamed and his condition was serious, so he has always been my focus. Every time he went to see him, his mental state was quite good, so I could chat with him every time and I knew his identity."

"Later, the family members came, and his students... also came. However, when his students came, someone quarreled with him. The sound was quite loud, but then the man left. I just heard the sound and didn't care about these things. After all, it was the patient's privacy."

"From now on, people will come to visit him one after another, almost every time they are different. It's also a coincidence that no other patients have been arranged to be checked in in that ward, so although there are quarrels there, no other problems have occurred."

"Thinking about it now, this is probably the greatest misfortune. If someone is there and hears the content of the argument, maybe... all this can be avoided."

Li Yang frowned slightly.

There are sometimes quarrels...

I'll go, the range of the murderer is quite large!

"Don't any of those people know their identities?" Li Yang looked at Liang Ke and asked.

"I don't know, I'm just a doctor. I can know that there are so many professions in patients. Where can I go to learn about the information of my relatives? But can't you get the police's intelligence? They should be able to see it when they look at the surveillance!"

Police intelligence... I don't want it for the time being.

"By the way, do you have the address of Wang Demen? If possible, I want to visit the people around him."

"Yes, his address is not very far from my house, so I remembered it after just one look..."

Li Yang recorded Wang Demen’s address and continued to ask: “The fire’s gas induced is because of the oxygen tank. Why did Wang Demen use the oxygen tank?”

"He is not in a mild condition and is weak. I specially asked the nurse to provide him with pure oxygen for a period of noon every day. This is something everyone knows."

"Then it seems that this clue is useless...what is the source of the fire? Have you really not seen where the fire can be caught? Is there any strange plug in the socket?

Something?”

The doctor thought for a while and shook his head.

"No, Wang Demen doesn't smoke. No one has ever smoked in the room when they come to visit him. As for the hands and feet of the socket, cleaning aunts and nurses go in and out of the ward every day. If there is anything wrong, they will report that the possibility of the socket ignition is very low. Moreover, when using the oxygen tank, the air pump on it has been connected to the socket beside the bed. The other socket is far away and is not enough to ignite the oxygen tank in a short time."

"Okay, it seems that there is no way to know the way of committing the crime in a short time." Li Yang took a sip of coffee, "But now it seems that Wang Demen is the target of the murderer. It is very likely that his student will take revenge on him, then it is very likely that he will take action during his hospitalization!"

Liang Ke nodded.

Suddenly, he saw Li Yang's raised head, showing a hint of confusion, but then he returned to normal.

Li Yang saw his appearance, but he didn't care.

"I'll go to Wang Demen's school first to ask... Let's see how the teacher's reputation is."

"Well, I wish you good luck. If you have any news, remember to share it with me." Liang Ke was unable to follow Li Yang to investigate the case, and his face seemed a little disappointed.

Li Yang left the cafe, looked at his wallet, and decisively chose to take a taxi to the school.

Just kidding! What money is saved in dreams!

When I arrived at the school gate, I saw the dilapidated gate, and suddenly, a sense of familiarity came to my heart.

Li Yang frowned. Why did he feel familiar with the school in his dream?

Li Yang didn't think much about it and walked straight to the guard room.

Li Yang, who had done a lot of things to attract business, was very thick-skinned at this time. He was smoking and chatting, and soon, he got together with the security department.

"Teacher Wang Demen!" The security guard took the China handed to him by Li Yang, revealing his burnt yellow teeth, and said with a smile: "He is the older teacher in the school! He taught here before I came to school. Usually, he saw that others were pretty good, and he would greet us every time he passed by, and he had never heard of anything he had."

"Is that true?" Li Yang also picked up a cigarette in his mouth. "Has Teacher Wang always been very nice to students?"

"It's not a good idea, but every once in a while, former students come to visit him." The security guard squinted his eyes and spit out a beautiful cigarette. "Every time he comes, he brings things to him! Hey, this teacher is good. The students he taught can still treat him as half of his parents, and can also give him some things during festivals. In fact, I also had the opportunity to be a teacher back then, thinking about me back then, I..."

Li Yang stopped the security guard with a dark face.

I will never kill you if I give you money!

"Then isn't there any abnormalities in Teacher Wang? Have you ever quarreled with someone?" Li Yang asked in confusion.

The security guard took a deep breath of cigarettes, and a thoughtful expression appeared on his face.

"If you want to say anything... it seems that there was really one time..."

"He's a very beautiful girl..."

"That day, in his office, the two of them quarreled for a few times and were stopped by other teachers."

"I never saw that girl again."
