Because he usually comes into contact with too many postcards of the Otaru Canal, the postman didn't notice anything special. But when it comes to sending them to mainland Japan, that's really not much, so he keeps a record every time.

According to the postman's records, two of them were actually sent to his home country that day, one of them was for Osaka, and the other was actually for Sapporo.

Because of the intervention of the police, the postman wrote the addresses of the two postcards. The one sent to Osaka was addressed to a female teacher in Osaka, and the police found that it was sent to her by a good friend of hers when she came here for a vacation, and there was nothing suspicious.

This is the second one.,It's sent to a house in the city of Sapporo.,The recipient is called Shuichi Hase.,Unemployed.,The house is the inheritance of his parents.,The main source of income is to do some odd jobs.,No criminal record.,It's a very homely Japanese.。

I don't understand how Zhang Yixin could send a postcard to such a Japanese man? So I immediately asked Xu Jin to contact China and ask them to check whether Zhang Yixin had any dealings with this Shuichi Hasei when he was in China.

As a result, it was found that Zhang Yixin had correspondence with this Hase-esuichi every month for more than a year. Although I don't know what they wrote in the letter now, I always feel that Zhang Yixin's disappearance is inseparable from this guy named Shuichi Hase......

Now that the police have got this clue, they began to contact the police in Sapporo, because they don't know whether Zhang Yixin is dead or alive now, so in order not to startle the snake, the police in Sapporo decided to secretly investigate this Shuichi Hasei first to see if there is anything suspicious about his whereabouts this month.

After a check, I found that there was nothing special about this Hase-suichi for nearly a month, almost as usual, occasionally going out to work as a casual worker, and staying here the rest of the time.

The local police also went to his house under the pretext of checking for termites, but they did not see anything suspicious. After I listened to it, I felt in my heart that the Japanese police were still unreliable, so I went into the house and checked it, and said that there was nothing suspicious?

It seems that if we want to find out if there is a problem with this Hasei Shuichi, we have to check it ourselves, and it all depends on others. So we left our hotel in Otaru early the next morning and drove back to Sapporo.

According to the address provided by the postman, we quickly found the house where Shuichi Hasei lived, and from the outside, it should have been some years old, and it gave a gloomy feeling overall.

The weeds in the yard were tall and dense, and the owner of the house was not a diligent fellow. In order not to arouse suspicion, we only lingered for a moment near the house before leaving.

Because after all, we are not Japanese, so some words and deeds are very easy to attract the attention of others, so Xu Jin drove us to the hotel first.

After lunch, a few of us discussed in our rooms and finally decided to hire a local detective to investigate Hase's whereabouts, which I can promise is much more detailed than the police.

Sure enough, two days later, Xu Jin came to the hotel with the whereabouts of Shuichi Hase, which was found by local Japanese detectives, and we took a closer look and found that this guy only went out to work two or three days a week, all to unload and unload some nearby supermarkets and the like.

It's just a part-time job, but it's stable. Shuichi Hase's entire income comes from this, and when he was hiring, he didn't see Shuichi Hasei come out much, and he hid at home all the time.

His parents both died in an accident a few years ago, and since then, Shuichi Hasei has been living here alone since he inherited his parents' property. Based on his travel time, we decided to visit his house tomorrow while he was going to work outside......

Because considering that Hase's working hours are not fixed, when Ding and I went to his house to investigate, Xu Jin and Uncle Li were responsible for keeping an eye on him so that he would not come back halfway.

After all, this is not China, and it is certainly not so easy to break into a private house in broad daylight. As soon as someone asks us a casual question, we will immediately reveal our stuffing.

But thankfully, during this time period, there are not many people on the streets, most of them are people who should go to work and go to school. Occasionally, a person passing by is also an old man in his last years.

In order not to attract the attention of passers-by, Ding Yi and I quietly went around to the back of the Hase's house, because he had a lot of miscellaneous items there, so after we jumped into the yard, it was easy to find a place to hide. To say that this Shuichi Hasei is really lazy, a good house allows him to live in such virtues!

After that, Ding Yi and I searched in the backyard for a long time and found a back door. It's just that the lock on the door has long since rusted into an iron lump, and the ghost knows how long no one has opened it.

Fortunately, for Ding Yi, this is not a problem, let alone a rusty lock, he can open it even if you die of drought. Sure enough, after a while, I heard a snap, and I saw that the broken lock that had just been hanging on the door had fallen to the ground.

Ding Yi first slowly pushed open the back door and found the end of the corridor. After entering, a musty smell came to my face! Because the orientation of this house is not good, the lighting is very poor, even though the sun is shining outside, but the inside of the house is still cool and shady.

In order to save time, Ding and I went separately, I went up to the second floor to look for it, and he stayed on the first floor to look for it.

There are two bedrooms and a bathroom on the second floor, and each room is a mess, and it seems that bachelors all over the world are the same!

But when I searched all the places I could find upstairs, I didn't find anything, let alone Zhang Yixin, not even a thing for a woman. Who knew that when I was a little disappointed, I suddenly heard Ding Yi downstairs calling me.

After hearing this, I quickly walked down the stairs, but I didn't see Ding Yi on the first floor? Could it be that he went out? Just when I was puzzled, I saw that the kitchen floor was suddenly lifted, and then I saw a figure coming out of the ground.

I looked carefully and found that the person turned out to be Ding Yi, good guy, my little heart was beating with fear from him!

So I said, "I'm going, why did you get down there?"

It turned out that when I went upstairs just now, Ding Yi was looking downstairs by himself, but when he went to the kitchen on the first floor, he found that the floor was empty!
