"There is nowhere to find the iron shoes, and it takes no effort to get them!"

Cheng Tian looked at the key in Zhao Tianzhen's hand, put down the flower pot and said with a chuckle.

"Alright, don't be poor, go open the door. ”

Zhao Tian gave Cheng Tian a white look and threw the key to Cheng Tian.

"It's really complicated!"

Cheng Tian inserted the key into the keyhole, then turned it clockwise three times, then counterclockwise, and turned it five times clockwise, and then the door clicked open.

"Xiaotian, there shouldn't be any mechanism in this room, right?"

Zhao Tianzhen cautiously walked into the house, looked around vigilantly, and asked with some concern.

"No, since Uncle Dong made the gate so complicated, there should be no mechanism inside. ”

Cheng Tian shook his head slightly, then walked to the light switch in the living room and turned on the light in the living room.

There is not much difference between the living room of Dong De's house and the living room of Tang Dou Manor, the furniture is all bought by Tang Dou, and Dong De seems to have no interest in fiddling with these things, and he has not replaced them, and there is no other decoration in the room, which is exactly the same as ordinary people.

"Xiaotian, there's nothing here, let's go to Uncle Dong's bedroom to investigate. ”

Zhao Tianzhen checked a little carefully in the living room, and didn't see any clues available, so he said to Chengtian.

"Hmm. ”

Cheng Tian nodded, and went up the stairs to the second floor with Zhao Tianzhen.

Because Dong De has always lived alone and has no friends, the upstairs room has things in his own bedroom, and the rest is empty, not even some of the most commonly used furniture.

"Xiaotian, you can also help me find out if there are any useful clues. ”

After entering Dong De's bedroom, Zhao Tianzhen began to rummage through boxes and cabinets to find clues.

"Okay. ”

Cheng Tian smiled and nodded, Zhao Tianzhen looked for the suitcase of the wardrobe, and Cheng Tian opened the various drawers, and the two of them quickly found something useful.

"Xiaotian, come and see, there are a lot of photos here!"

Zhao Tianzhen found a digital camera and a stack of photos from a mezzanine in the wardrobe, in addition to Dong Qingqing's photos, there are also some photos of ancient tombs.

"Could it be that Dong De really didn't remember the map, and why did he go to the ancient tomb?"

After looking at the photos one by one, he said with a slight frown.

"I don't know, the current clues can't be strung together into a complete story line at all. ”

Zhao Tianzhen shook his head lightly.

"Then let's go ahead and look for it again. ”

Cheng Tian said softly.

"Hmm. ”

Zhao Tianzhen nodded, and the two put the photo on the desk in the room, and then continued to look for clues.

In the end, the two turned the bedroom upside down, and never found anything of value, but they also found a letter that was not sent, and the words "Daughter Dong Qingqing collected" were written on the envelope. Cheng Tian and Zhao Tianzhen hesitated again and again, but finally did not open the envelope, but put the envelope away, preparing to teach it to Dong Qingqing in person after seeing her.

"Xiaotian, it seems that Uncle Dong really didn't leave anything behind. ”

The two searched for about an hour, and by this time it was already dawn outside, and the weather was fine today, and the sun had come out before eight o'clock in the morning, illuminating the horizon.

"Well, it should be like this, but it's a pity that Uncle Dong is dead, leaving too many mysteries to explain. ”

Cheng Tian nodded lightly, and then sighed regretfully.

"Then let's go, let's go meet Dong Qingqing first, and leave it to the colleagues of the criminal police team to search carefully." ”

Zhao Tianzhen said softly.

"Well, let's go. ”

Cheng Tian nodded, and Cheng Tian simply cleaned up the bedroom, took away the photos and envelopes, and then left Villa No. 8 and drove to Chuntian Elementary School.

When he arrived at the gate of Chuntian Elementary School, Zhao Tianzhen showed his ID to the security guard at the door and reported his intention, and the security guard let Cheng Tian drive into the elementary school.

"Room 301 of the classroom dormitory building, this is it, I'm knocking on the door. ”

Zhao Tianzhen and Cheng Tian soon came to the third floor, the first room was 301, and Zhao Tianzhen walked over and rang the doorbell.

"Who?"

Soon a young woman's question came from behind the door.

"Hello, is it Miss Dong Qingqing? I am Zhao Tianzhen, a policeman from the Donghai City Criminal Police Squadron, and I want to ask you about the situation. ”

Zhao Tianzhen thought about the cat's eye at the door and showed his ID, and replied softly.

"Come in, two. ”

It was quiet for a few seconds, and then the door clicked open, and it was the young woman in the photo in Dong De's hand, that is, Dong De's biological daughter Dong Qingqing.

"Hello, I'm Zhao Tianzhen, and this is Cheng Tian. ”

After entering the house, Zhao Tianzhen briefly introduced himself and introduced Cheng Tian.

"Hello. ”

Cheng Tian glanced at Dong Qingqing, smiled and nodded to her.

The real Dong Qingqing is almost the same as in the photo, but Dong Qingqing at this time is a little colder, but it is understandable that it is normal for a person to be in a bad mood for the New Year in the dormitory.

Chuntian Primary School is a relatively famous private school in Donghai City, with strong teachers, the teaching environment is very good, the natural conditions of the teacher's dormitory are not bad, the room is heated, the decoration is also very good, one bedroom, one living room and one bathroom also have a balcony, electrical appliances and furniture are also very complete, of course, it is not excluded that these things are bought by Dong Qingqing himself.

Dong Qingqing looks about his early twenties, with a simple ponytail, wearing a woolen sweater, a pair of beige trousers, slippers on his feet, no powder on his face, a good-looking melon seed face, a pair of bright eyes with softness and a little sadness, slender eyebrows, a small but straight nose, lips with a slight pale pink, skin is also very fair, his hands do not have long nails, he does not wear nail polish, and he does not wear other jewelry except for a gold necklace.

"Do you two want something to drink? I have beer and juice and milk and green tea here. ”

After Chengtian and Zhao Tianzhen sat down, Dong Qingqing, as the owner of the room, asked the two of them with a smile.

"No, just bring me and him a glass of water. ”

Zhao Tianzhen smiled and shook his head.

"Okay. ”

Dong Qingqing poured a cup of hot water for the two of them in front of the water dispenser and sent it to the two of them.

"Thank you. Miss Dong, how long have you been a teacher at Springfield Elementary School?"

Zhao Tianzhen and Cheng Tian took the hot water, thanked Dong Qingqing with a smile, and then Zhao Tianzhen asked Dong Qingqing.

"I've been applying here for more than two years since I graduated from university. ”

Dong Qingqing replied with a smile.

"Do you have any other relatives and family?"

Zhao Tianzhen continued to ask.

"No, I don't have a family after my mother passed away three years ago. ”

Dong Qingqing raised his right hand, stroked the bangs in front of his forehead, and then shook his head lightly.
