"I wonder who it was. What kind of fight did you have? Do you even have the strength or the ability to use it?" Yu Jingyan rebuked.

Silang: "Brother Yu, listen to me. When I was waiting for you guys in the police station, I suddenly sensed a killing intent coming from the surroundings, you should know that I am very sensitive to killing intent, so the moment I stepped out of the police station, I saw a figure quickly escaping, I didn't think too much, and chased after him, that person was very fast, he turned seven corners and entered an alley, I caught up to him and found that he was already waiting there, in the darkness I couldn't see his face clearly, and asked him who he was. He didn't say anything, and directly brandished his dagger towards me.

Yu Jingyan frowned, although Silang's words were simple, Yu Jingyan knew very well just how powerful Silang was, who had the Evergreen Saber in his hands, was. It was rare for a person to be able to escape from Silang's blade.

"What are the characteristics of that person?" Yu Jingyan asked.

Silang: "Adult male, tall and big, other characteristics I don't know."

Jeb immediately called his colleagues, telling them to carefully look for the identities of the people fighting Silang.

"I can't believe he dares to mess around in front of the police station. Who is that guy?" Jeb said.

Silang shook his head. Yu Jingyan was also confused, he stared at Silang for a while, but in the end, he did not start discussing about this issue. Instead, he changed the topic and said: "Let's go to the hospital to look for Dong Chun first."

Silang: "Brother Yu, did you guys find out anything from Ze Cheng about him attempting to kill Dong Chun?"

"No, I can only confirm that Ze Cheng hates Dong Chun to the core. Sigh, Silang, you should be more careful in the future. Yu Jingyan said.

"Who?" Silang asked.

Since Jeb was present, Yu Jingyan did not go into details, and instead took out his phone to call Chen Xi.

"Hey, Lao Chen, where are you?" Yu Jingyan asked.

"Zhang Si's grilled meat, I've just finished roasting it, what, you guys want to come back for dinner? "In that case, let me roast some more …" Chen Xi said.

"No, immediately come to the police station, don't stay here alone, Silang was just attacked, the opponent is very strong, I'm afraid you will be in danger." Yu Jingyan said.

"Holy shit, he'll be here soon!"

A few minutes later, Chen Xi arrived at the entrance of the police station, the skewers still in his hands.

On the way, Yu Jingyan explained the situation with Ze Cheng and also mentioned the matter of Silang's attack. He warned Chen Xi to be careful.

"Putting aside the fact that Silang was ambushed, how do you think that Ze Cheng had a deep grudge with an old man?" Chen Xi asked.

Yu Jingyan was also very confused, looking at it now, there was a deep grudge between Ze Cheng and himself, but their life and social background did not have any sort of connection, so how could these two people, who had nothing to do with each other, have a grudge?

When he arrived at the people's hospital's neurology department, Dong Chun was lying on the sickbed, staring at the ceiling in a daze.

Yu Jingyan and the others observed outside for a while, before Chen Xi asked: "If Ze Cheng really wants to kill Dong Chun, you can do it during the surgery."

Yu Jingyan: "That won't do, during the operation, there are too many eyes, nurses, assistants, anaesthesia and more are all in the operation room, even if Ze Cheng wanted to kill Dong Chun, it would not be easy to find an opportunity to do so."

Chen Xi: "Can't you just cut open the artery with one slash?"

Yu Jingyan: "Even if you say that, in that case, it wouldn't even be considered a medical accident, and would directly become a murder. "I think, although Ze Cheng hates Dong Chun, he doesn't want to kill him immediately, that's why he would do such a thing with the medicine. If he could use the medicine to kill Dong Chun, Ze Cheng would have a chance to disguise his murder as a medical accident, what do you think?"

Chen Xi: "I don't know."

Jeb accepted Yu Jingyan's words, thinking that Ze Cheng had wanted to take care of Dong Chun secretly. However, he did not expect Dong Chun to be saved, and only after he realized that his actions had been exposed, Ze Cheng would admit that he had deliberately increased the quantity of the medicine.

After looking through Dong Chun's medical records and basic information, Yu Jingyan decided to go into the ward and chat with Dong Chun.

Pushing open the ward's door, Yu Jingyan and the others came to the sickbed, and after observing Dong Chun's situation, Yu Jingyan's face became ugly, Silang's, and Chen Xi's face revealed surprise.

"Hey, do all three of you know him?" Jeb asked in a low voice.

The three of them shook their heads at the same time. The reason they revealed such an expression was not because they recognized Dong Chun.

Rather, it was because the three of them simultaneously discovered that the soul in Dong Chun's body was not complete …

Yu Jingyan saw that the soul in Dong Chun's body, from his chest all the way to his head, had completely disappeared, and everything below his chest was still there. In other words, Dong Chun's soul was incomplete, and the missing portion had disappeared without him knowing.

Silang and Chen Xi's eyesight were limited, and could not see the truth as clearly as what Yu Jingyan could see, but they could more or less see that Dong Chun's soul was incomplete.

"Dong Chun?" Yu Jingyan opened his mouth.

Dong Chun slightly turned his head on the sickbed, and an old face entered everyone's eyes. He looked to be in his seventies, with a face full of wrinkles.

"Doctor, are you looking for a room again?" Dong Chun said vaguely.

Yu Jingyan knew very well that the Dong Chun that was not in a good mental state would treat them as doctors, so he said: "It's fine, it's just looking around, how do you feel?"

Dong Chun pointed to his abdomen. His abdomen was a wound that had not fully healed after the operation, and was still covered with gauze. "It's a little painful."

"Oh, this is a normal postoperative reaction. Is there anything else that feels uncomfortable?" Yu Jingyan asked again.

"It's gone, it's still okay …" "Hey, who are you guys? Are you guys here to search?" Dong Chun asked again.

Yu Jingyan and the others looked at each other, knowing that old man Dong Chun's memory was extremely poor. He had just treated them as doctors, and now he had forgotten their identities.

"Right, let's come over and take a look. How do you feel?" Yu Jingyan repeated.

"Oh, it hurts here …" Dong Chun pointed to his abdomen.

"Do you know Ze Cheng?" Yu Jingyan asked.

"Ze Cheng... Ze Cheng... Is it my clan's Ze Cheng who sold vegetables? " Elder Dong Chun asked with a blank expression.

"It's Ze Cheng from the general surgery of the People's Hospital, Doctor Ze Cheng." Yu Jingyan said.

The old man shook his head. I don't know, I've never been there. Are you looking for Ze Cheng? Then go to the hospital, he isn't in my house … Oh yeah, my house's young man selling vegetables, Ze Cheng, are you looking for him? "

Yu Jingyan frowned, he pointed to Dong Chun's abdomen and said: "The Ze Cheng I'm talking about, is Ze Cheng who will be treated by the people's hospital."

"Operation? Do you want an operation? No, I'm afraid of pain. I don't want an operation... "Who are you?" A new blank look appeared on Dong Chun's face …

Looking at the incoherent old man Dong Chun, who was unable to communicate with him, Yu Jingyan understood that he couldn't get any useful clues from him. He then helped the old man cover himself with a blanket, and indicated for everyone to leave the sickroom.

"Doctor, have you finished your rounds?" Before leaving, Dong Chun asked again.

"Finished."

Everyone went to the on-duty doctor's office and communicated with the doctor in charge of Dong Chun's condition.

"Doctor, how is Dong Chun?" Yu Jingyan asked.

Doctor: "Although Dong Chun has been diagnosed with Alzheimer's disease, but from some details, he doesn't seem to be that kind of patient. I don't know if it's a special case or if his previous diagnosis was wrong."

"What does that mean?" Yu Jingyan asked.

Doctor: "The patients with Alzheimer's disease are divided into three stages. The first stage is classified as moderate to severe, and judging from Dong Chun's short-term memory loss, he should be classified as moderate Alzheimer's disease, but his ability to function is not affected, he can take care of himself, he can urinate normally, he can walk around, he can even buy things on the streets. Just based on his ability to function, he should be classified as a first stage, a mild Alzheimer's disease.

Yu Jingyan nodded his head: "I understand, either my diagnosis was wrong, or it was a special case, right?"

However, in front of the Officer Jeb, it was not good to say anything more. He continued to introduce: "We are a neurologist, and are mainly responsible for the symptoms of Dong Chun's Alzheimer's disease. As for the abdominal surgery and the drug poisoning after the surgery, I don't really know much about it.

"Lao Yu, where do you think we should go investigate?" Jeb asked.

"What's your name?" The doctor suddenly asked Yu Jingyan.

Yu Jingyan scratched his head, thinking that the doctor was not that narrow-minded. Just because he had expressed his opinion, why did he ask for the name?

"My name is Yu Jingyan, what can I do for you?" Yu Jingyan said snappily.

You are Yu Jingyan! Disrespect, disrespect! I have long heard from colleagues that you used a folk method to remove rare live intracranial parasites for patients. I am sorry, Mr Yu, I did not know that it was you. The doctor stood up and bowed towards Yu Jingyan.

Yu Jingyan blushed, he knew that the doctor respected and respected his because he helped Cheng Dawei get rid of the Gu Worm, and said embarrassedly: "You are too courteous, I am just a bystander, I can't compare to your Academy …"

"Mr Yu, you are too modest. Since you were able to extract the intracranial parasites for your patients without having to undergo surgery, I believe you have a very good understanding of the brain. I have a question, which is if the hippocampus of the patients with brain diseases is removed, will they completely lose their memory?" Mr Yu was too modest, the fact that you were able to remove the intracranial parasites without having to undergo surgery, you must have a very good understanding of the brain.

Yu Jingyan looked confused, then smiled and said: "We will discuss this issue in the future. I came this time mainly to help Officer Jeb investigate the matter of Doctor Ze Cheng giving Dong Chun the wrong amount of medicine."

The doctor immediately nodded his head, and looked at Yu Jingyan with eyes full of worship, and said: "Oh, it turns out to be that matter. Speaking of it, it's strange, Doctor Ze Cheng has a good reputation in the hospital, and does things very seriously, he started working two years earlier than me, and has not had any problems for many years, but he actually drugged Dong Chun wrongly, sigh, no one is perfect, it's possible that because he's too tired, and can't avoid making mistakes."
