In fact, our country's law recognizes gender reassignment. If someone suffers from gender cognitive impairment, after gender reassignment, they can go to the public security bureau with a gender identification certificate from a tertiary hospital to change the gender on their ID card.

However, although the law allows it, in the eyes of many people, transsexuality is basically equated with perversion.

After Xie Jingchen heard Liu Lirong talk about Liu Zhi's gender change, he knew that he had thought wrong before.

When I saw the case of Luo Qingqing before, I thought the murderer might be in a similar situation to Luo Qingqing, but in fact it was very different.

Luo Qingqing was born male and psychologically male. Due to the influence of drugs she received during pregnancy, she developed female signs.

Liu Zhize was born male and psychologically female. After transitioning, he changed his gender and became female.

In addition, Liu Lirong showed Xie Jingchen a series of evidence such as chat records, which showed that Liu Lirong, Liu Hong, and Sun Guifang had not met each other in recent years and only relied on online text communication.

If the deceased were Liu Hong, Sun Guifang and their children, the first suspect who killed Zhou Yang and Fang Ling would be Liu Zhi.

Transgender changes the body structure, not genes and facial features.

Comparing the photos of Liu Zhi before his gender transition, we can see that his eyebrow shape is exactly what Fang Ling said during his lifetime, which is a unibrow.

Xie Jingchen exchanged information with Sun Wu who came to pick him up, and immediately identified the suspect. The rest was the arresting work.

Wang Zixian didn't know yet that Xie Jingchen and Sun Wu had identified the suspects who killed Zhou Yang and Fang Ling, and he was investigating at Professor Pei's house.

At that time, Professor Pei's wife Feng Guanghua's death occurred in a pseudo-secret room, and Wang Zixian wanted to find out how the murderer could escape.

Xie Jingchen had previously speculated that the murderer might have been hiding in Feng Guanghua's home from the beginning, which Wang Zixian also agreed with.

Because the time is really too short.

From the murder to the escape, he even cleaned the bottom of the iron pot that was the murder weapon and put it back on the stove. This whole process was completed within twenty-three minutes, or even less.

The detail that made Wang Zixian confirm this was the tea on the desk.

After all, Feng Guanghua was the professor's wife, and she still did a good job in hospitality. At least all the guests who came could drink the tea she brewed.

At that time, Xie Jingchen and Xiao Zhao came together, and Feng Guanghua entertained them briefly and poured them tea.

However, there are three of them, but there are four teacups on the coffee table in the living room.

Except for the two cups of tea that Xie Jingchen and Xiao Zhao did not drink, the tea cup used by Feng Guanghua and the extra one were all empty.

Wang Zixian guessed that before Xie Jingchen and Xiao Zhao arrived, Feng Guanghua already had a guest, but she didn't know why he wanted the previous guest to hide when a new guest arrived.

Since Su Ye's fingerprints were found in the small room where Feng Guanghua died, he had been suspected before, but now Wang Zixian felt that the "guest" could not be Su Ye.

Su Ye is a student of Professor Pei Chengjing. He is said to be a student, but in fact he is almost half a son. Su Ye will often appear at Pei Chengjing's house, and sometimes even eat and live in Pei's house, almost like half a master.

If it were Su Ye, Feng Guanghua would not serve tea in the living room and there would be nothing to hide.

So, what kind of guest must be hidden and cannot be seen by outsiders at all?

As early as when Professor Pei's body was first discovered, Su Ye came to help the Pei family take care of the funeral and took the academic information that the Pei family needed to keep confidential back to the school. Feng Guanghua's matter probably had nothing to do with academics.

Could it be a lover?

Probably not. It is true that a lover's words should not be seen by outsiders, but he would not drink tea in the living room so politely.

Is there anything that Feng Guanghua cannot let outsiders know?

Does this matter have anything to do with Professor Pei?

Wang Zixian remembered that Xie Jingchen had suspected Feng Guanghua at that time. She had the motive to kill Lin Ruirui. Could it be that the "guest" was the murderer who paid for the murder?

Just guessing

I think, since the identity of the murderer cannot be determined, we still need clues and evidence.

As for how the murderer escaped after committing the crime, Xie Jingchen had previously speculated that he escaped with the help of a rooftop.

Wang Zixian is also planning to start from the rooftop first. Whether it is confirmation or elimination, it will be an effective result.

The old community where Professor Pei's home is located all has six floors.

It is said to be six floors, but in fact there are seven and a half floors. Residents on the first floor have a garage downstairs, and residents on the sixth floor have a rooftop and a small attic upstairs.

Due to various reasons such as lighting, humidity, and floor height, the most expensive and easiest-to-sell houses of this kind are often three- and four-story houses.

Each of the first to fifth floors has its own advantages, and the sixth floor is often the last one left.

For sales reasons, there are many sellers of six-story properties who buy six and get seven for free on the sixth floor.

In other words, if you buy the sixth floor, you will get the seventh floor for free.

There is at most a small attic leading to the rooftop on the seventh floor.

The same is true for the sixth floor of the building where Professor Pei's family lives. The small attics on the sixth and seventh floors belong to the same family and have direct access to the rooftop.

Wang Zixian went upstairs and knocked on the sixth floor, but no one answered. Then she went to the property management company to check the owner's information.

Due to the murders that occurred in the community in the past few days, many families felt unlucky and moved away. The houses were sold at low prices, and the owner information was updated several times.

After checking the information, I learned that the owner on the sixth floor was the real estate speculator who rented out the garage on the first floor.

That real estate speculator is used to being a landlord. He takes out a loan to buy a house, rents it out immediately after buying the house, and uses the rent to repay the mortgage. This is a common practice of many real estate speculators.

Naturally, he also rented out the house on the sixth floor.

The real estate speculator was not in the city. After checking the tenant information remotely across the city, he told Wang Zixian that his tenant had just checked out more than a month ago, and asked him to go to the property to get the spare key.

Go inside and check.

There was something as big as the death of a person downstairs. If he hadn't found out earlier, it would have been difficult to rent out his house.

Wang Zixian took the key given by the property management and entered the door on the sixth floor.

The room on the sixth floor is similar to Professor Pei's house. It is quite large and has an extra indoor staircase leading to the seventh floor.

There is indeed a small attic on the seventh floor.

There is a door in the small attic, which can be opened directly to the rooftop. This door is a security door, and it can only be opened from the inside after it is locked.

There are three such small lofts on the rooftop, and each sixth-floor owner of this house has one.

One of the attics has been renovated into a fully transparent glass flower room, with a variety of flowers growing in it. The light from the roof is very good, and the flowers grow well and look pretty good.

In addition to the small attic, many ropes were pulled on other parts of the rooftop for drying clothes.

After looking around on the rooftop, Wang Zixian determined that in addition to the three attics, there was also a simple, locked, rusty metal escape passage on the side of the building.
