"That's not true, in the past year, I have not been in good health, I have been hospitalized twice, during the hospitalization. The two children have been arranged for nurses to take care of me, but my wife is still not at ease and has to go to the hospital to take care of me. ”

"My daughter Yaohua lives near the hospital, and my wife lives at Yaohua's house at night and accompanies me at the hospital during the day."

"Your two elders have a really good relationship, they are really in love!" Zhao Zimeng sighed.

"Young couples are old companions, if they dislike each other when they are old, wouldn't they be worthy of their oath when they were young." Professor Cai glanced at Aunt Cai affectionately.

"Professor Cai, when were you hospitalized twice?"

"Once at the beginning of the year, old woman, what month is it?"

"Yes—it's the beginning of March!"

"Yes, it's the beginning of March. Stayed in the Nine Heavenly Temple. ”

"What time was the second time?"

"The second time was - the end of August and the beginning of September, and I stayed for eight days."

Zhao Zimeng couldn't help but think: This time is very close to the time when the Cai family moved. That's when the gang of tomb robbers probably infiltrated No. 117 and finally determined the location of the cave entrance.

"Aunt Cai, haven't you been home in the past eight days?"

"Back - back twice, got some clothes." Aunt Cai replied very cautiously.

"Professor Cai, Aunt Cai, when you came home from the hospital, was there anything unusual in the house?"

"No—nothing out of the ordinary, my wife is a clean-loving person, and the things in the house are still in their original places, and if someone touches them, she will be able to see them."

"Yes! It is true that no one has touched the contents of the house. Aunt Cai said.

"Oh, have the floor tiles in your room changed? I mean: have you ever been pried on? ”

"Absolutely not, I have a habit of cleanliness, and on the first day I got home, I cleaned all the houses and found no signs of pried floor tiles." Aunt Cai is very sure.

"Well, is this No. 117 only for you and your old family?"

"Yes, I like to be quiet, when I paint, I don't want anyone to disturb me, I can't even have noise, my wife and I are the same character, we just fancy the quiet environment of No. 117, so we decided to live there." Professor Cai said.

"We heard that there was another person living in it later." Zhao Zimeng is talking about Rao at a glance.

"Half a year ago, Xiao Rao in the village moved in. His younger brother got married, there were many people in the house, he came to discuss with me, and the neighbor Lao Cao also helped to intercede, Xiao Rao He wanted to make a transition in my house, as long as he found a house, he moved away immediately. ”

"He said that he just slept on the 117th, ate at his parents' house, and usually worked a lot of overtime in the unit, so he wouldn't spend much time there."

"We saw that Xiao Rao was quite thoughtful, not like the kind of noisy person, so we agreed. Of course, we are also a little selfish. Professor Cai told the truth.

"Selfishness? What do you mean by that? ”

"Comrade Zhao, that's the case, in the past year, our old couple has not been in good health, in case one of them is sick, and the other person can't move, a young man lives in, and he usually has a care." Professor Cai said.

"What unit does this Xiao Rao work in?"

"He himself said that he worked at the Zhongguan grain depot, and he had to work two or three night shifts a week, and he didn't have anything to do in normal times."

"I think this young man is quite good, since he moved in, he has taken over all the things that my family has done to change gas and buy coal-based."

"People are also diligent and often clean the yard; When he was at home, he mostly stayed in the house and read, very quiet, not the kind of crazy person outside, he never brought anyone into the door, very conscious. Professor Cai seems to have a good impression of this Rao.

"Yes! The old man was sick this time because Xiao Rao and I sent him to the hospital, the first night he took care of the old man, our family Yaohua saw it, and quickly hired a nurse to take care of the old man, Xiao Rao saw that there was a nurse, so he went back. ”

"The old man and I couldn't get enough of it, so we gave him a painting." Aunt Cai also likes this young man.

Rao also mentioned that Professor Cai gave him a painting.

"Xiao Rao helped us a lot this time, he helped us move things, and later sent us to Hoop Bucket Lane. After the family moved, he left without even eating, what a good boy. Professor Cai said.

"In what month did Rao Glance live in No. 117?" Zhao Zimeng continued to ask.

"I moved in half a year ago, in April this year. Wife, am I right? ”

"Yes, Xiao Rao moved in in April." Aunt Cai repeated.

"Well, I understand, when did the demolition of this Huaigu Village begin, do you remember?"

"The demolition started in September."

"When did you hear about the demolition?"

"It spread in March of this year."

There was news of the demolition in March, and this Rao moved into No. 117 in April. This can't be a random coincidence, right?

After this conversation, two people came into Zhao Zimeng's sight: one was Professor Cai's second son, Cai Yaohui, who knew both archaeology and cultural relics identification.

He is in the antique business, is it possible that opening an antique shop is a pretext, and secretly doing it is a business of reselling cultural relics?

This person is suspected of committing a crime, Zhao Zimeng did not break the casserole and asked in the end, Cai Yaohui should have the key to No. 117.

During Professor Cai's hospitalization, he had the conditions and enough time to go to No. 117 to determine the location of the thief cave.

The other person is the tenant Rao Guan, No. 117 has always been only lived by Professor Cai and his wife, this person suddenly moved in, and the check-in time is such a coincidence.

As a tenant, Rao Guanguan must have the key to No. 117, and when Professor Cai is hospitalized and Aunt Cai is not at No. 117, Rao Guanguan is also qualified to sneak into Professor Cai's room to do this.

He has been living in No. 117 for a while, and he should be familiar with the environment around No. 117 and the situation in the courtyard, and the suspicion of this person cannot be ruled out.

Thinking of this, Zhao Zimeng suddenly became excited: the tomb robbers may not need to sneak into Professor Cai's room, the entrance of the robbery cave is only three or four meters away from the tomb door, and the distance between the back wall of the main house and the backyard wall is five or six meters, as long as the tomb robbers find the location of the tomb entrance, they can determine the location of the robbery hole.

Zhao Zimeng suddenly found that he had a very big negligence, and a cool air suddenly appeared from his back.

The location of the ancient tomb is under the bamboo forest and woods behind the courtyard wall of No. 117, according to the distance between the entrance of the robbery cave and the entrance of the tomb, it can be known that the entrance of the tomb may be in the courtyard wall of No. 117, and the tomb robbers can only determine the specific location of the cave when they determine the direction of the tomb and the location of the entrance of the tomb.

And to determine the direction of the tomb and the location of the tomb entrance, this matter is not too difficult, as long as you use the Luoyang shovel to make a few holes above the tomb road and the tomb entrance.

If this judgment is true, then there must be a cave left by tomb robbers within the walls of the backyard of 117.

Before entering 117, the tomb robbers must have dug caverns near the tomb passage and the tomb entrance.

According to Professors Nie and Jin, the tomb robbers determined the specifications, grades, direction of the tomb and the entrance of the tomb through caving, and only when the direction of the tomb and the entrance of the tomb were determined, the tomb robbers would begin to implement their tomb robbery plan.

In the previous investigation, he actually ignored this, and he decided to go to the crime scene again.

Zhao Zimeng got up to say goodbye and quickly ended the conversation with Professor Cai and his wife.

Professor Cai sent Zhao Zimeng out of the alley, and he said to Zhao Zimeng: "Comrade Zhao, if you have any questions, you are always welcome to come to Hoop Bucket Lane." ”

"Thank you and Aunt Cai. Goodbye, Professor Cai. ”

Zhao Zimeng pushed a little way, and after seeing Professor Cai walk into the alley, he took out the Xiaofu machine (a mobile phone in that era) from his pocket and dialed the phone on duty at the Dongcheng District Police Station: "Hey, is it the Dongcheng District Police Station?" ”

"This is the duty room of the Dongcheng District Police Station, who are you?" A man's voice came from the other end of the line.

"I'm Zhao Zimeng of the Municipal Criminal Investigation Team."

"Captain Zhao, hello, I'm Chen Baobao, the duty officer, what's the matter with you?"

"Is your Director Zhang at work?"

"Director Zhang just entered the door."

"You ask him to answer the phone."

"Captain Zhao, wait a minute, I'll call Director Zhang."

Chen Baobao put down the phone and ran out of the duty room to call Director Zhang, his voice was very loud: "Director Zhang, Captain Zhao's phone." ”

This was followed by the sound of running, followed by the sound of panting.

"Captain Zhao, I'm Zhang Minghuai, please speak."

"Director Zhang, you can bring someone to the scene of the crime now, protect the scene, and we will be there in a moment."

"Understood. I'll bring someone there now. "Director Zhang didn't ask any questions." Judging from the tone and content of Zhao Zimeng's speech, the situation is very urgent.

Zhao Zimeng exhaled, then put the little fortune machine into his handbag, and rode the bicycle and sped forward.

At this time, it was already about 7:10, and it was the rush hour for work, and the cars on the road were passing one by one, and on the bicycle path, the traffic was moving in one direction, and on the sidewalk, the people going to work were in a hurry.

The life of the day began with a sound and a bright start.

Zhao Zimeng's first thought was to call the Dongcheng District Police Station, because they were relatively close to the scene of the crime.

Normally, workers on the demolition site would not have started work so early, but if the deadline is particularly tight, it is difficult to say, the police have already inspected the site, and all work can be carried out as usual.

At 7:45, Zhao Zimeng rode his bicycle into the gate of the criminal investigation team.

Zhao Zimeng had just pushed the bicycle into the carport, and Ling Hu Yunfei and Xiang Daimo also came on bicycles.

"You guys came just in time, Dai Mo, you go to drive the car, Yunfei, you go upstairs and take a look, there are a few people called a few people." Zhao Zimeng stepped forward.

"Team Zhao, what's the situation?" Xiang Daimo said.

"Let's talk about it in the car."
