The ambulance from the hospital came and went.

Mrs. Cheng's niece called Cheng Liangbin's wife and cried to inform that the old lady was gone.

Soon the funeral home's car came and went.

Looking at the black car shadow that was gradually disappearing, Ke Yang was even more firm in his judgment.

According to Mrs. Cheng's niece, Cheng Liangbin informed her mother the afternoon before yesterday that she would come to pick her up for heart surgery today. This shows that Cheng Liangbin was sure to raise money for his mother's surgery the day before yesterday.

Cheng Liangbin died suddenly that night, and his deposit balance was less than 30,000 yuan, and he was still 120,000 yuan away from the operation fee, indicating that he did not get the money as scheduled.

"Then it is very likely that when Cheng Liangbin contacted Wu Tongzhou the afternoon before yesterday, Wu Tongzhou agreed to Cheng Liangbin's request......"

Following Ke Yang's train of thought, the more He Zhi thought about it, the more chilled he became.

If it is true as Ke Yang's speculation, Wu Tongzhou also has an unshirkable responsibility for Mrs. Cheng's death.

"Let's go, let's go to the hospital where Dr. Cheng works, maybe there will be some clues left in Dr. Cheng's medical record."

Ke Yang immediately contacted Xiao Nan, and Xiao Nan very happily promised to rush to the hospital to meet him immediately.

Not many patients go to the hospital to see a psychiatrist, and Cheng Liangbin's office is still empty. The director of the hospital office politely invited Xiao Nan, Ke Yang, and He Zhi into the house.

"Dr. Cheng's patient information is in the cabinet, unlike other departments that use computers to manage medical records. The content of Dr. Cheng's conversations with the patients is handwritten, and sometimes after the patient leaves, the doctor will make some additions and notes on the medical records. You have to look at it, but the hospital must fulfill its duty of confidentiality to patients, and hope that patient information will not be leaked to the outside world. ”

After the director of the hospital finished speaking, he took the door and went out.

Xiao Nan and Ke Yang opened the filing cabinet to look through the information, He Zhi sat on Cheng Liangbin's office chair, looked at the recliner in the corner, and imagined the situation when Wu Tongzhou came to see a doctor.

In front of the doctor, what is the situation of Wu Tongzhou's physical disorder?

"Found it!"

Xiao Nan put the medical record in his hand on the table, and Ke Yang and He Zhi gathered around together.

The patient's name is Wu Tongzhou, age 27......

The description of the condition was scribbled, and the content of the two-month consultation was written in a thick book, and some margins were marked with notes in red pen.

"It doesn't seem like anything special."

With the speed at which Xiao Nan flipped through, Ke Yang finished reading ten lines at a glance.

The content of the case is a question and answer between some ordinary doctors and patients, and Wu Tongzhou's purpose is very simple, he wants to cure the physiological dysfunction as soon as possible and give birth to a baby.

"Could it be that we are overthinking ......"

Although Xiao Nan believes that Wu Tongzhou is related to the disappearance of Song Meijun and He Jing, he can't get conclusive evidence, so he can only force himself not to suspect Wu Tongzhou. She admired Ke Yang's reluctance to pursue Wu Tongzhou, so she also tried her best to cooperate with Ke Yang to find evidence.

Today was again in vain, Xiao Nan was a little disappointed.

"Show me again."

He Zhi took the case and flipped it up again.

"Nightmare! Look here......"

In the margins of the last page of the medical record, there is a small red text written like an ant. The word nightmare was circled, and a big exclamation mark was placed next to it.

"Could it be that Wu Tongzhou's illness is related to nightmares? No, I speculated at the time that Cheng Liangbin had discovered Wu Tongzhou's secret. ”

"Then the nightmare of Wu Tongzhou is a secret that can't be said......"

He Zhi and Xiao Nan looked at Ke Yang at the same time.

"It must be! Dr. Cheng didn't write it down on the medical record, but he must have remembered it. ”

Ke Yang said with certainty.

"Then I will immediately ask people to check the call records of Wu Tongzhou and Cheng Liangbin in the past few days."

There seemed to be a dawn in front of him, Xiao Nan picked up his mobile phone and called his colleagues.

Ke Yang reminded: "It is necessary to focus on checking the call records of Wu Tongzhou and Dr. Cheng the day before yesterday. He then added that based on his understanding of Wu Tongzhou, Wu Tongzhou should not use his real-name registered mobile phone number to talk to Dr. Cheng, and they may contact each other through online chat software.

"Whichever way they contact them, they can now find out that the police force has just introduced the latest technology, and the cyber police can access the suspect's online chat history at any time."

Xiao Nan just hung up the phone after explaining the task with his colleagues, and He Zhi's mobile phone rang.

Seeing Wu Tongzhou's name, everyone looked at each other.

"It shouldn't be about Doudou's custody, now Lan Hao is his opponent."

Staring at the phone screen, He Zhi hesitated to answer.

"He should have asked you to ask for guilt, you dealt with He Jing's funeral alone, he, as He Jing's husband, was unwilling to see He Jing for the last time."

Xiao Nan had already heard that Wu Tongzhou had complained about the irregular management of the funeral home, and he was He Jing's family, so he shouldn't have let He Zhi handle He Jing's funeral without notifying him.

Sure enough, Wu Tongzhou accused He Zhi in an unhappy tone, He Zhi was listening silently, and occasionally heard Doudou watching cartoons. I haven't seen Doudou for more than a month, He Zhiqiang resisted the urge to return to Doudou immediately, and after listening to Wu Tongzhou's reproach, he said lightly:

"If you miss He Jing, you can go to the cemetery to see her, she is with my parents now."

There was a sudden silence on the phone, and the voice of the cartoon disappeared. He Zhi's ears were close to the mobile phone, and it took two feeds before Wu Tongzhou's lukewarm voice came. He asked He Zhi to send him the address of the cemetery, and he would take Doudou to see He Jing.

It may be that Doudou heard the words that he was going to take her to see his mother, and Doudou's excited voice came from the mobile phone, but Doudou asked, "Do you want to take me to see my mother?" There was silence on the phone again.

It should have been Wu Tongzhou who covered the microphone, and then hung up the phone.

After He Zhi sent the address of the cemetery to Wu Tongzhou, she couldn't help but want to tell her that it was best not to take Doudou to the cemetery on the mountain in cold weather, but the message on her mobile phone showed that she was rejected.

At dinner, Ke Yang followed his mother in and out of the kitchen, helping to get vinegar for a while, and grabbing to peel garlic for a while.

"Ke Yang, what's going on? How can I go out with you and come back and become a child! ”

Mrs. Ke said while bringing the freshly cooked dumplings to He Zhi, in fact, she was very affected by her son's sudden change. The son has lived alone for more than ten years, and it is rare to cling to her like when he was a child. This feeling made Mrs. Ke feel as if she had returned to her youth.

"No matter how old you are, as long as you have a mother, you can be a baby. Maybe Ke Yang wants to express his love for you! ”

He Zhi understood that Cheng Liangbin's mother's death deeply touched Ke Yang.

"Ah, isn't that what the song says about having a mother's child like a treasure!"

Old Lady Ke laughed from ear to ear.
