Also, Xu Lang is a well-known psychiatrist.

It stands to reason that anyone who can become a psychiatrist should be very sensitive, but why didn't he find out that his son had a psychological problem?

Did you not notice it, or did you notice it and let it develop?

If Xu Lang didn't notice the psychological changes of the original owner, it may be because the other party was his son and subconsciously ignored it, but what about the woman in red?

Even if he doesn't care much about his son, but there is an outsider around his son, no matter how big the person is, he should pay attention to it.

What's more, the woman in red has been in existence for a long time, a full three years.

In addition, Xu Lang disappeared, and he disappeared when the original owner committed the last crime.

Did he disappear, or was he killed by his original owner?

After Xu Lang disappeared, the original owner realized that he was sick, stopped killing, and turned into a detective, is it so sudden?

Most serial murderers are actually addicted, just as people who love to drink have alcohol addictions, and people who love to smoke have tobacco addictions, serial murderers are also addictions, invisible and deadly.

A lot of times, it's not that they want to kill, it's that the addiction hits, and they have to kill someone.

Of course, this may seem like a justification for homicidal maniacs, but it is.

The original owner, as a serial murderer who committed 44 murders in a row in nine years, how could he say that he stopped committing crimes?

Isn't there a need for a process during this time? How did he restrain his homicidal addiction?

Xu Mo couldn't figure it out, how did the original owner do it, in a very short period of time, he transformed himself from a murderer to a detective, and appeared at the scene of the murder many times?

Didn't he know that for a murderer, corpses, blood, and other things would irritate him?

All in all, there are many suspicious points in the original owner's murder diary, and it seems that everyone who appears next to the original owner has a problem.

"Is the original owner sick, or is everyone around him sick? That's a big question. ”

For things that can't be figured out, Xu Mo doesn't think about it for the time being.

When he went out today, Xu Mo planned to adapt to the surrounding environment first and buy some daily necessities.

The place where Xu Mo lives is very convenient.

There are 24-hour convenience stores and supermarkets outside the community, and there are bus stops and fixed taxi ranks not far from the community.

A twenty-minute walk to the west will take you to Silver University.

During this time, you will pass by a large shopping mall, where you can find almost everything you need for life, whether it is jewelry, clothes, or electronic products.

Although Xu Mo had finished backing the online map of Baiyin City these days, he still didn't want to be too far away from home.

On the one hand, he needs to be familiar with the surrounding environment little by little, on the other hand, the city map of Baiyin City is really a bit difficult to explain, many of which have not been drawn into it, and if he wants to be really familiar with the city, he has to rely on himself to explore little by little.

After walking for about ten minutes, Xu Mo arrived at the mall.

According to the icon prompt of the mall, Xu Mo came to the sixth floor.

The sixth floor is full of electronic products, and the clerks here are very enthusiastic, and the first thing Xu Mo said when he saw it: "Little handsome guy, you are here again, what do you need today?" ”

When Xu Mo heard this, he was slightly stunned, and subconsciously asked, "Do you know me?" ”

The female clerk was also stunned when she heard this, looked at Xu Mo in a little surprise, and said, "I'm Lili, you booked a camera and lens with us before, did you forget?" ”

“……”

After listening to the female clerk's explanation, Xu Mo instantly understood that the original owner should come here often, and the consumption every time he came was not low, otherwise the other party would not remember him.

"Oh, it turned out to be Sister Lili, something happened during this time, which caused me to have problems with my memory, I'm really sorry."

"Oh, you don't have to explain, I know, you're a great detective, it's normal not to remember me."

Immediately, the female clerk changed the topic and asked, "What do you want to buy today?" Is it still a lens? ”

"Let's take a look at your phone and computer first."

"Okay, you're here today, the latest silver mobile phone just arrived today, you can just try it."

With that, the female clerk went to the back of the counter to get her mobile phone.

Xu Mo took a brief look at it, and decided to buy this latest silver mobile phone, and by the way, he bought two very button mobile phones.

It is worth mentioning that the world's button phones have not been eliminated, but have developed a variety of different styles, and some functions are better than smartphones.

When buying a mobile phone, Xu Mo reissued a mobile phone card.

After that, Xu Mo bought computers and home monitoring equipment, as well as voice recorders and pocket monitoring probes and other things.

If someone else comes to buy it, the clerk will definitely ask the other party for what it is for, and may even tell the other party directly.

But the original owner is an old customer here, and the female clerk named Lili seems to know that Xu Mo is a detective, so when Xu Mo tentatively asked if there was one, the other party didn't think about it, so he took out the latest product.

After buying these things, Xu Mo bought the 50 fixed focus with an aperture of 0.8 under the recommendation of the other party.

It cost a lot of money just to buy these things, and fortunately the original owner was not short of money.

The reason why he didn't buy a camera was because he really didn't have a shortage of cameras.

The third room in the house is filled with cameras of various brands and models.

It seems that the original owner's choice of photography department was not random, he really liked photography.

The money for these cameras and lenses is enough to buy a house in a good location, and it is no wonder that the female clerk in the mall is so enthusiastic and familiar when she sees him.

After everything was purchased, Xu Mo left in the other party's happy eyes.

Then, Xu Mo went around the mall, bought a lot of small things during the period, and went to the seventh floor to eat a delicious meal by the way.

Not to mention, the food here is still delicious, at least much better than takeout.

In this way, Xu Mo walked around the mall for three or four hours before returning to the community with his things.

When I arrived at the door, the master in charge of delivery also arrived.

After moving everything into the room and sending the master away, Xu Mo called someone from the furniture company to change the door lock.

For someone to be able to enter and leave his house freely, this made Xu Mo very insecure, especially since there were big secrets hidden in the house.

Of course, Xu Mo himself is the biggest secret.

After changing the lock, Xu Mo installed the monitoring probe by himself, except for the bathroom, which was not installed, the probe was installed in all other places, including the bedroom where he slept.

That way, if anyone comes in or out of his house, he will be the first to know.

When all this was done, it was already night, and after cleaning up the room, Xu Mo went out for dinner again.
