Renxi City and Hanyuan City are close to each other, as long as we start now and take the highway all the way, it will take less than three hours to reach Xiaohe Town.

Hong Haonan got in touch with the police in Hanyuan City while we drove off.

Now there have been two poisoning cases in Renxi City, and although we have some clues, the facts of the cases are still not very clear, and we have not even grasped the exact evidence.

So I asked Lin Zifan and Jiang Tingbai to stay in Renxi City to assist the local police in continuing the investigation, and I took Li Meng and Xue Hang to drive to Xiaohe Town in Hanyuan City.

In the car, neither of us spoke. I went to Xiaohe Town again after many years, and even I didn't know why I had to return to Xiaohe Town.

Is it just because the net was collected here in the past? Or is it because his friend Ye Yun disappeared in Xiaohe Town?

So what can I prove or understand when I return to Xiaohe Town this time?

Nothing was known, but my gut told me that I had to go to this place.

Because this place is the beginning of everything, there will also be some relevant clues about the Hexagram Organization here.

Li Meng didn't speak, because she knew the purpose of my trip, and she knew that my brain was still very chaotic at this time, and my thoughts were not clear.

Xue Hang didn't speak because he didn't like to talk in the first place.

Also, since the establishment of the Serious Crime Team, everyone has experienced so many cases and things, Xue Hang believes in me very much, and he believes that I must have my own reasons for doing this.

Since I don't want to say, it's useless for him to ask.

In this way, the three of us sat in a civilian police car and set off together towards Xiaohe Town, Hanyuan City.

Soon, we received a call from Hong Haonan, who said that the local police had found Lin Kangcai's current address, and then I received a location.

After setting the positioning to the navigation destination, I subconsciously increased the throttle and the police car sped away.

After arriving at the address of Xiaohe Town, we were faced with a four-story residential building with local characteristics. I don't know why, the buildings in Xiaohe Town look relatively dilapidated and old, and there are very few high-rise buildings, basically at a height of about five floors.

There was also a lot of commotion in the streets, and everyone was speaking in dialects they didn't understand. Everyone is dressed in a very local culture, and everyone likes to wear a straw hat on their heads.

According to the police investigation, Lin Kangcai lived on the second floor of this residential building.

There was a slight knock on the door, and there were several crunching noises from the tin door.

The gate has two levels, the outside is an iron rusty door with a railing, and the inside is an equally worn and painted wooden door, and there is a small window on the wooden door that replaces the mirror on the security door.

After a while, the small window of the wooden door was opened, revealing a pair of eyes and a small half of a face.

"Who are you looking for?" A man's voice came, and it was no surprise that the person who was talking to us was Lin Kangcai who we were looking for.

"May I ask if it's Lin Kangcai?" I made up my mind and asked seriously.

"I'm Lin Kangcai, who are you?" The man confessed his identity and turned to ask us.

As long as it's Lin Kangcai, I made up my mind, took out my police ID, and said seriously: "We are from the Public Security Bureau, and there are some things that we need to know from you." ”

Lin Kangcai looked through the small window on the wooden door, his eyes kept spinning, he first looked at the documents in my hand, and then at the three of us.

In the end, Lin Kang retracted his head and closed the small window on the wooden door.

Immediately after, he opened the wooden door, and then opened the outer wooden iron door, and we entered Lin Kangcai's house.

Xiaohe Town is close to the southwest border, the weather is very hot, because of the characteristic geographical environment, the air here is very humid, which makes people feel very unaccustomed.

Walking into Lin Kangcai's home, it is a very typical layout of a small local building, the structure of the house and the furnishings in the house, which has the feeling of an old movie.

The whole house is very long, and in the center of the living room is an equally narrow coffee table, which is covered with a floral tablecloth. Next to the coffee table is a brown wooden openwork sofa with a long cushion on top.

If you look in this direction, you will find a green painted wooden window, with three windows, all of which open outward, and the narrow windowsill is full of green plants such as orchids, and the long leaves hang down, and there are no flowers in sight.

There is not much furniture in the house, the TV, refrigerator, and wardrobe are covered with square scarves, which is full of age.

In short, all this shows that the owner of the house is a retired old man who still retains the living habits of the older generation.

Lin Kangcai is such a person, his home dress is very casual, white hurdle vest, gray casual shorts, holding a worn-out pu fan in his hand, blowing an electric fan that seems to strike at any time.

I really can't imagine that such a person is a person who can use his own chemical technology to refine D products.

Maybe this is the big hidden in the city? I secretly smiled bitterly in my heart.

"How many police comrades are looking for me?" Lin Xingxing suddenly asked us, and very politely adjusted the angle of the electric fan to let the fan cool us.

Xiaohe Town is really hot, and now we are sweating, it is really the kind of heat that is uncomfortable, no energy, and I don't want to say a word.

Facing the electric fan, I took a deep breath and asked seriously, "Do you know Ye Junxi?" ”

"Ye Junxi?!" Hearing this name, Lin Kang directly showed an expression that was almost shocked.

I don't know if it's because he didn't expect us to mention this name, or because he himself and Ye Junxi have some past that people dare not recall.

I nodded and repeated the name: "That's right, it's Ye Junxi." ”

Lin Kangcai blinked, nodded slowly, and said lightly: "I know, he is my former student." ”

"According to our police investigation, you have a history of making and smoking D products yourself." I said in a deep voice.

Hearing this, Lin Kang smiled a little embarrassedly: "At that time, I accidentally refined the D product, but I don't know if it was not, driven by curiosity for a while, I tasted it and smoked it......"

"It is precisely because of this incident that Ye Junxi, a 'chemistry genius' who was pinned on by the school, dropped out of school, do you know about this?" I looked at Lin Kangcai and asked a very critical question.

The swing speed of the pu fan in Lin Kangcai's hand gradually slowed down, and the emotions in his eyes were a little complicated, and then he let out a long sigh: "I only found out about Ye Junxi's withdrawal from school later." I didn't expect that one of my wrong actions could bring such a big blow to him, I am sorry for my position as a teacher, I am sorry for being a role model, and I am sorry for the bad influence on students......"
