The ultrasound examination form found in the backpack was a result from two months ago while the HIV positive test date was a month ago.

Xiao Lou carefully found that the date of these inspection documents wasnt the same. Obviously, Cheng Mu first found out that she was pregnant and then found herself infected with HIV.

From the perspective of time, Cheng Mu couldnt have sex with people everywhere after becoming pregnant. Thus, it was likely that this child was Zhao Quans and it was also possible that Zhao Quan passed on the HIV to her.

Realizing this, Xiao Lou felt the back of his spine become cold. He immediately handed the inspection sheet to Yu Hanjiang. Yu Hanjiang took a careful look at the inspection sheet and whispered to Cheng Mu, HIV, was it Zhao Quan who infected you?

Cheng Mus face had no colour and she nodded stiffly.

Xiao Lou worriedly asked, That the other six girls, did they have a check up?

Cheng Mu spoke softly, After I found out, I asked them to go to the hospital for a check up. They are all fine.

Xiao Lou and Yu Hanjiang glanced at each other. The seven girls actually went to the hospital to check for HIV but in the process of inquiry, they tacitly all concealed it. It was likely that the other six all knew Cheng Mu had HIV and was the most likely to kill Zhao Quan, but they didnt directly give up Cheng Mu out of sympathy or other reasons. They were asked who had the greatest feud with Zhao Quan and they all said they didnt know in a perfunctory manner.

Yu Hanjiang had interrogated a lot of criminals but in the face of this poor woman, he couldnt ask too many questions. He had to whisper, You and Zhao Quan, it isnt simply a relationship of opening a room together. Can you tell us the truth?

Xiao Lou gave her the office seat and handed her a cup of warm water. Miss Cheng, you sit down first and slowly say it.

Cheng Mu took a sip from a glass of water, gently clenched her fists, took a deep breath to adjust her state and spoke slowly. In fact, I have a history of marriage.

X looked at her in an unexpected manner.

Cheng Mu was very pretty with long and curly hair. She was young and only in her early 20s. It was hard to imagine she actually had a history of marriage.

She closed her eyes and whispered, He was a senior I knew when I was in university. Originally, I wanted to take the postgraduate entrance examination but then I found out I was pregnant. I loved him very much so I decided to give up the postgraduate entrance examination and have this child.

He was a hospital intern at the time and didnt have much income. I understood he worked hard so I didnt have a wedding ceremony or take wedding photos. We just got a license and rented a house to live in. It was a bare marriage.

Then he was later admitted to a residency at a hospital and his income gradually increased. He said he would raise me and our child. I stayed at home and did the laundry and cooking for him. I thought life would get better but one time, he said he had the night shift at the home and couldnt go home. I was worried that his stomach wouldnt be well eating takeaway so I personally made dinner and sent it to him, only to find out he was involved with a nurse in his department.

Cheng Mu looked very cold when she mentioned her ex-husband. She had apparently been frozen to this man a long time ago. He actually cheated while I was pregnant. I knew this and collapsed. I was accidentally hit by a car when crossing the road and the child didnt I filed for divorce and he agreed with a few remarks. The marriage dealt a serious blow to me and I became disappointed with men.

She spoke up to here and was silent. Her hands holding the glass of water slightly trembled. After a moment, she adjusted her mood and was calm and cold. I adjusted my mood and went out to find a good job and rented a place. I downloaded a friends with benefits software and made appointments whenever I had physiological needs. It was convenient and fast. I would never get married again and wouldnt have to bear the betrayal of a bad man.

Cheng Mu added, Zhao Quan was the third man I made an appointment with. He was handsome, young and very considerate. Whether in life or in bed, he was the gentlest man I had ever met.

I did have sex with him first and had no feelings, but he was so good at talking. He sent me messages every day with warm questions. If the weather was cold, he would thoughtfully buy me gloves and scarves, personally sending them to me.

He was the type of warm man that girls liked best. He was considerate in every aspect. Sometimes I would get stomach pains during my period and he knew how to take care of me, giving me brown sugar and ginger water to drink.

Once, we were lying in bed and chatting after sex and I couldnt help talking about my bad marriage experience. He gently hugged me and said this wasnt my fault. He loved me very much and would take care of me later. It was better for us to be in a fixed relationship. To be honest, my brain wasnt working and I was really touched by him. I agreed to have a formal relationship with him.

Cheng Mu thought up to here and also felt regret.

In fact, how can a normal straight man know so much about girls cosmetics and even the red colour for our mouths? Most men cant tell what is red, rouge red, sweetened bean paste red, agate red

Zhao Quan knew everything about girls, which means he studied them. Either he was a one in a million man willing to study cosmetics for his favourite girl or he was 99% a scum man with rich experience, allowing him to know a lot. In fact, judging from his behaviour of being on that friends with benefits program, he was more likely to be a slag man.

Unfortunately, I was blinded by his sweet words and ignored this key thing.

Cheng Mus fingernails deeply pierced the palm of her hand before she calmed down. I used to take safety measures when making an appointment with him. I was wary of him in the beginning but he was too good at coaxing girls My ex-husband was a careless person but Zhao Quan was the exact opposite. He always made me feel warm in my heart with small details. Gradually, I let down my guard.

He said he wanted to be with me for a long time and I was shaken.

During that time, we didnt take any safety measures or contraceptives. We played more openly, which was very exciting and addictive. In May this year, I found out I was pregnant. She paused and lowered her head slightly. I was in a very good mood at the time. I had been wounded and found it hard to believe in men. It was Zhao Quan who pulled me out of the mud and made me hope again

In fact, Zhao Quan didnt pull her out of the mud. Instead, she fell into a more terrifying abyss.

Cheng Mu closed her eyes and said, After finding out the pregnancy, I took all my savings and was going to buy a house together after he graduated. I couldnt wait until the baby was born and even selected furniture for the nursery.

Zhao Quan was interning at the company and was very busy. I wasnt in a hurry to tell him about the pregnancy and wanted to wait until the weekend to give him another surprise. Before I could his six girlfriends added me and pulled me into the group.

There was a self-deprecating smile on Cheng Mus face but tears floated in her eyes. Her voice quivered as she exclaimed, I found out that Zhao Quan actually stepped on six boats! When I was pregnant, he was buying a cake for Yue Xiaoquan and celebrating her birthday from 7:00 to 9:00. Then he showed up at my house at 9:30 and went to bed with me! I was so sick that I almost vomited up my meal!

I really broke down at that time. I pulled all the curtains in the room shut and stayed in the dark room all night. I didnt know what did I do? Why do I always meet such men?

She gently held her belly and whispered, The child certainly couldnt be born. He had a relationship with so many people and it was impossible for him to marry me. If the child was born, how could I explain the type of person the childs father was?

Here, she could no longer maintain her calm. Her tears came out uncontrollably like a faucet had opened. Xiao Lou hastily handed her a packet of tissues.

Cheng Mu choked up and wiped away her tears, whispering, Thank you.

She grabbed the warm water and took two sips. Once her calm was restored, she continued, I went to the hospital again. This was my second lost child and I thought I wasnt qualified to be a mother in my life. However, it wasnt over yet. Before the operation, I needed to take a blood test. At that time, I suddenly thought that Zhao Quan had slept with so many people. Did he have a sexual disease? Therefore, I asked the doctor to check it for me.

The result of the inspection was predictable. Not only did she lose her baby, she also got HIV.

Cheng Mus mood at that moment was difficult to describe in words. It was probably the entire world had collapsed.

The first time, she was betrayed by a scum man. She divorced her partner and lost confidence in men. She decided to no longer marry in this life and to live alone. However, Zhao Quans emergence gave her hope. She thought that Zhao Quan could save her and restore her faith.

Her original only sex, no feelings concept started to shake and she fell in love with Zhao Quan. She believed in Zhao Quan and was willing to be pregnant for Zhao Quan. Unexpectedly, Zhao Quan held her high and then dropped her heavily!

This time, her body couldnt recover from the fall. Cheng Mus heart was full of anger from the betrayal and hatred from being infected with HIV. This was enough to support her picking up the butchers knife.

Xiao Lou previously said that the other girls talked about their future, wanting to forget the scum man and start a new life. Only Cheng Mu didnt mention her future at all

It was because she knew that the moment she got on the train, she had no future.

Cheng Mu held a tissue and sobbed, The moment I found out that I got HIV, I completely collapsed

Xiao Lou gently placed a hand on her shoulder and spoke softly, I can understand you.

Zhao Quan destroyed her so she decided to destroy Zhao Quan.

Cheng Mu looked up at Xiao Lou with a bitter smile. I am infected with HIV, dont you think I am dirty?

It isnt your fault you arent disgusting at all. It is Zhao Quan who is disgusting.

Cheng Mu was silent for a moment before saying, I was alone at home all day and had nothing to eat. I was desperate, my mind was a mess and I didnt know what to do. Later in the WeChat group, Si Yi said that we were cheated by a scum man and this was also fate. She organized everyone to eat a meal together while also summarizing the characteristics of a scum man so as to not be cheated later.

I saw the messages in the group and suddenly remembered that I wasnt the only victim. What if the other girls were infected? I quickly sent the results of my examination to the group.

All the girls in the group were furious. They only had Zhao Quan as a boyfriend and they were definitely fine. I took safety measures before dating Zhao Quan. Then where did the HIV come from?

Zhao Quan mustve definitely slept with an unclean woman. Cheng Mu frowned and said, Sister Xiaoyan speculated that it was during the winter vacation of this year. Zhao Quan told all of us that he was returning to his hometown. Maybe he couldnt help sleeping with a prostitute or a girl he knew, got HIV and then passed it onto me.

I had the girls hurry to check. If Xiaoyans calculations were correct, he hadnt passed it onto the other girls. This was because everyone was busy at school and had no time to sleep with him.

Song Xiaoyu directly started crying and went to the hospital again. Everyone went to the hospital to see her while also checking for HIV. At that time, the six girls lined up without saying a word. A few days later, the inspection results came out and everyone got together again.

They were all fine. Perhaps I was just unlucky and didnt use any protection that time with Zhao Quan in bed

Cheng Mu smiled bitterly. We all agreed with the plan proposed by Yue Xiaoquan. We took protection measures, bring a mask and gloves to cut Zhao Quan dozens of times. However, I thought that if the girls really got revenge on him, after some time, he would come out to get revenge on other girls. What should I do if he makes appointments with other women through the friends with benefits software and spread the disease everywhere?

So I said that I have a plan B that can solve all the problems. They asked curiously about the plan and I told them that I would tell them when Yue Xiaoquans proposal was executed and I watched Zhao Quans reaction

I had already decided to kill Zhao Quan but I didnt tell them about my plan because I didnt want to scare them.

It is only by Zhao Quan dying and having his thing cut off that he cant continue to harm girls.

Cheng Mu wiped her eyes and the expression on her face was restored to a calm state. She said, Zhao Quan pulled me down to hell. I should send him to hell and let him go to accompany my innocent child.

She suddenly leaned over and took off the boot on her right foot. There was a portable fruit knife hidden in the delicately beautiful knee-length black boots.

She removed the scabbard and Xiao Lou saw that the sharp knife was covered with blood. Cheng Mu calmly placed the fruit knife on the table and declared, This is the knife I used to kill Zhao Quan. After killing him, I hid it in my boot.

So far, all the other clues of the crime had been found and she actively handed over the tool to commit the crime.

Yu Hanjiang and Xiao Lou were both silent.

Cheng Mu clearly explained and her testimony had no loopholes. It was just that the truth was even sadder. Cheng Mus experience was too painful. She was a very good girl but she met two scum in a row who ruined her life. Finally, she decided to end it herself.

The train to hell, the person who created this image was no longer important. Ultimately, it was Cheng Mu who replaced the desktop photo of Zhao Quans phone. It was because she wanted Zhao Quan to take this train to go to hell and accompany their child.

Xiao Lou and Yu Hanjiang took Cheng Mu to the 9th carriage. They had to pass by the 4th carriage where the other six girls were gathered together. They all guessed that the murderer was Cheng Mu but they didnt want to personally tell the truth.

Cutting Zhao Quan many times, castrating him and finally killing him was the Plan B that would solve everything.

Liu Xiaoyans eyes were filled with tears and she was the first one to walk over to hug Cheng Mu. The other girls also began to walk one by one, stretching out their arms and giving her the gentlest hug between girls.

The passengers were puzzled by this scene and turned to watch curiously. However, they didnt say anything.

Cheng Mu smiled, waved to them and turned to follow Xiao Lou and Yu Hanjiang.

Song Xiaoyu buried her face in Liu Xiaoyans shoulders and secret shed tears. Yu Lin turned her head and clenched her fists while a trace of being unable to endure it flashed on Yue Xiaoquans face. Yan Rurus eyes were red and Si Yi pushed up her glasses, whispering, It is over. Forget that scum and start a new life.

Song Xiaoyu whispered, That what about Cheng Mu?

What about Cheng Mu? She didnt want to start over. She was so tired that she decided to end it. This train was the end of Zhao Quans life but also the end that she chose for herself.

[In the 4 of Hearts secret room, the person who killed Zhao Quan is:

A. Cheng Mu, B. Yue Xiaoquan, C. Yan Ruru, D. Liu Xiaoyan, E. Si Yi, F. Yu Lin, G. Song Xiaoyu]

The familiar prompt on the suspension box appeared again. Xiao Lou and Yu Hanjiang once again looked at the names of the seven girls and tacitly pressed the A option.

[Congratulations to the challengers Xiao Lou and Yu Hanjiang for perfectly clearing the 4 of Hearts secret room. All clues have been found and the instance clearance time is 39 hours, 22 minutes and 08 seconds. The instance clearance score is S grade and the world record for the 4 of Hearts secret room has been refreshed!]

The clearance message popping up on the floating box proved that there would be no more cases on the train.

In the 6th carriage, Li Zhemin who harmed three families was finally killed by Mrs Mei.

In the fourth carriage, the person who pursued the fast sense of conquering girls and stepped on N boats, Zhao Quan was killed by the despairing Cheng Mu.

The direct connection between the two cases was Shu Pings daughter, Shu Xiaomeng, who happened to know the group of female friends.

In fact, on this train, there was only one core theme related to the two cases. This was the train for the funeral of scum men. Cherish life and stay away from scum men.
