Xia Jiali took Yang Yu and Wang Ziwen to the tenth floor of the mine's administrative office building, the information center of Daqingshan Mining Company.

Xia Jiali entered the account number and password at her workstation to log in to the company's OA system. She searched according to the keywords provided by Yang Yu.

In an instant, the document about Ding Shi's personal transfer was retrieved. And the date of the publication of this document is yesterday afternoon, not at all three days ago. In other words, when this document was released, Ding Shicheng was already dead. Obviously, the purpose of this document is to create a reasonable reason for Ding Shicheng to go to Mine 1012.

Yang Yu asked Xia Jiali to generate an electronic version of the document in PDF format, then download it and send it to Yang Yu's mobile phone.

During today's one-day investigation, I did not expect that a breakthrough was made in Ding Shicheng's personnel transfer first. This is a big gain for Yang Yu.

This document illustrates what someone is covering up, and several points are completely clear, the first is that the human resources department was involved in the fraud, and the director of the coal washing plant, Mr. Wang, was also involved in the deception and cover-up. The document was obviously issued yesterday afternoon, but he cooperated with the counterfeiters and said that it was issued three days ago.

And who is the person who instructed the human resources department and Director Wang to commit fraud? Yang Yu actually began to suspect in his heart that it was Ding Zicheng. But there is one thing that is not clear, that is, Ding Zicheng and Ding Shicheng are siblings, and he will not design a game to blow up his younger brother, so it seems that the cost is too great. Or, could it be that Ding Shicheng's death was an accident? These puzzles require Yang Yu to find strong evidence.

Yang Yu also has a clue, that is, the black coal core hidden in the pocket of her jeans. She wanted to find Han Jing from the First People's Hospital tomorrow and ask her to help test what this thing was. If DNA information can be found, it will be possible to follow this clue and find a third person hiding at the site of the 1012 mine explosion. Uncover this mysterious third party.

After a busy day, Yang Yu and Wang Ziwen just returned home in the evening. Ding Zicheng also drove to Yang Yu's house. During the day, Ding Zicheng was not in the city, and no one knew where he went.

Ding Zicheng is visiting Yang Changqing this time. He already knew that Yang Changqing was bailed out by Yang Yu. Ding Zicheng was carrying a few nutritional products in his hand, claiming to be to suppress Yang Changqing's shock.

When Yang Changqing saw Ding Zicheng, his face was tepid. In fact, Yang Changqing was very resentful of Ding Zicheng in his heart. When there was a mining accident in the mining area, he no longer reported it to him, the chairman, as soon as possible, but when he was taken away by the public security, he reported it to Yang Yu. This approach seems to have only one purpose, which is to let Yang Yu return to Hoh.

"Sit down, Lao Xue, pour Zicheng a cup of tea. Yang Changqing asked Ding Zicheng to sit down, and at the same time asked his wife to pour tea for Ding Zicheng.

Yang Changqing lost his previous enthusiasm, and he could hear from his words that he had an opinion on Ding Zicheng. The reason why he is still called Zicheng instead of Ding Zicheng is that it has saved a little face for Ding Zicheng.

"Chairman, I really didn't expect such an accident. My brother was killed on the spot, and I was saddened. At the time of the accident, I was resting at home. Qiao Xisan was seriously injured, he called me and said that there was an accident, that my brother was killed, he was injured, and then there was no follow-up. I thought, since there was such a big accident, Qiao Xisan didn't explain the situation clearly, and I needed to verify it, so when I finished the verification and was about to report to you, the chairman, I knew that the public security had taken you away. The stakes are high, and I can only tell Yang Yu the news as soon as possible. Ding Zicheng had thought about his rhetoric many times before he came, and it seemed that his statement was leaky.

"If Qiao Xisan reported it to you, then who notified the Public Security Bureau?" asked Yang Yu.

"Oh, I don't know, I can only guess. I think Qiao Xisan may not only call me, but he may also call 110, or call the safety production duty room in the mining area. I'm busy running relationships during the day today, and I'm also begging someone to see if the chairman can be released on bail. Unexpectedly, Yang Yu had already taken the chairman out. As soon as I came back, I hurried to see the chairman. Ding Zicheng had already thought in advance that Yang Yu would ask such a question, so he did his homework in advance.

"Why did your brother go to Mine 1012 in the middle of the night?" asked Chairman Yang Changqing.

"That's right, it turns out that my brother works in a coal washing plant. Three days ago, several departments related to the company's operation held a meeting to discuss and decided to outsource those mines that we are not willing to mine ourselves and have a certain mining value. Everyone unanimously recommended that my younger brother Ding Shicheng be in charge of the work of reclaiming the old mine. Three days ago, the Ministry of Human Resources issued a document to transfer Ding Shicheng and Qiao Xisan to the mining department. As a result, the next day, the partners in the community offered to survey Mine 1012. My brother is an anxious man, and he didn't expect him to lead his men to survey Mine 1012 in advance overnight. But no one expected that something would happen in Mine 1012. The death of my brother hit me hard, he only got married last year, and the child is only about a year old......" Ding Zicheng said, pulling out a tissue and pretending to wipe away tears.

Speaking of which, it is clear that I, Ding Zicheng, am a victim. Everything else that was to be asked was pushed back by Ding Zicheng reasonably.

Yang Yu doesn't want to have a showdown with Ding Zicheng now, because it is difficult to reverse the current situation by relying on a personnel transfer document with a date deviation, and it is impossible to completely clear his father's name. Yang Yu secretly warned himself in his heart to be calm. She will continue to investigate further and find more evidence.

Everyone has their own agendas, so tonight's meeting is just a polite cutscene, and even both sides listen to each other's reality. So, in just half an hour, the meeting of the night was over.

Sending Ding Zicheng away, Yang Yu talked to his father again. For the time being, she didn't want to show some of her judgments and collected evidence, and she didn't want her father to get too deep and entangled in this issue.

When Yang Yu talked to his father, he only said something unrelated to the case.

Early the next morning, when Yang Yu and his family were having breakfast, the development of the situation took a big turn.

A group of people carried slogans made of white cloth, one banner read, "Yang Changqing returns my husband! The murderer pays for his life!" and another read, "Parole on medical parole is fraudulent! Skynet is restored and not leaked!". Ding Shicheng's wife was holding a one-year-old child in her arms, with a white cloth tied on her head and wearing filial piety clothes. There was a crowd of people around, including a number of TV and newspaper reporters.

The group blocked the gate of Yang Changqing's villa and set up loudspeakers to demonstrate there.

This scene can be seen by a discerning person at a glance, and this is an organized, premeditated, and targeted activity.

This event didn't just happen at Yang Changqing's doorstep. The second place occurred in front of the outpatient building of the First People's Hospital of Hoh. Dozens of men and women carried banners with black letters on a white background, which read: "Doctor Han Jing falsified Yang Changqing's medical parole!

The third place actually happened at the gate of the Public Security Bureau, and there were dozens of men and women, holding a banner with black characters on a white background, which read, "For the official is not honest, act as the black umbrella of Yang Changqing's murderer!"

In the second and third departments, not only dozens of people were lifting weights to make trouble, but also a number of report letters were sent to the Municipal Commission for Discipline Inspection, the Public Security Bureau's Commission for Discipline Inspection, the Hospital's Commission for Discipline Inspection, television stations, and daily newspapers. The report letter respectively reported that Han Jing had faked Yang Changqing's bail, and that Zhao Yijun, deputy director of the Public Security Bureau, acted as a black umbrella for Yang Changqing.

The demonstrations in the three places were held at the same time to Yang Changqing, and at the same time, the news media cooperated in disseminating them. This series of events instantly caused quite a stir in society.

Before 9 o'clock in the morning, the police car of the Public Security Bureau came to the gate of Yang Changqing's house and took Yang Changqing away again.

Deputy Director Zhao Yijun Shuanggui was investigated by the organization, and Han Jing was also taken to the Public Security Bureau for questioning and investigation.

When Yang Yu saw the police take his father away again, his mother shed tears of despair. The father's case implicated Dr. Han Jing and Deputy Director Zhao Yijun.

These three sets of combination punches knocked Yang Yu unconscious. made Yang Yu instantly feel the seriousness of the matter, which made her feel a sense of powerlessness from the depths of her heart.

She can now confirm in her heart that all this was planned by Ding Zicheng, and these three activities were the reason why Ding Zicheng disappeared during the day yesterday.

During the day yesterday, when Yang Yu was investigating the case, Ding Zicheng was also in contact with the layout of the relationship. I didn't expect Ding Zicheng to do things so absolutely, and he could be so black.

Yang Yu knew that the little coal core and the personnel work transfer letter about Ding Shicheng that he found yesterday were already very weak and weak in front of these big killing moves that Ding Zicheng had sacrificed.

Yang Yu temporarily handed over the small coal core and the personnel transfer letter to his mother for safekeeping. She now understands that at present, she has lost the time to find evidence again, and the only thing she can do is to find Ding Zicheng and ask, what does Ding Zicheng want?

Yang Yu called Ding Zicheng, but Ding Zicheng never answered Yang Yu's call. The reason why Ding Zicheng did this was because he was hanging Yang Yu's appetite. He knew that the initiative and control of things were now in his own hands.

One morning, Yang Yu made more than 20 calls to Ding Zicheng, until it was close to 12 o'clock at noon, Ding Zicheng finally answered the call from Yang Yu.

"Ding Zicheng, I won't talk nonsense to you, you and I know it. Let's talk about it in person. Yang Yu tried to stay calm, but her heart was full of anger.

"Well, you come to my house at one o'clock in the afternoon. But before you come, I suggest you check out the noon news that will air soon. Ding Zicheng hung up the phone after speaking.

After Yang Yu finished making the call, he immediately switched to the local noon news program with the remote control.

“...... I received a report this morning...... The public security armed police thoroughly inspected the 1012 mine of the Daqingshan Mining Company and found that a large number of detonators were piled up in the mine's roadway. Mine 1012 has signed a contract with a third-party company...... Fortunately, there was an insider who reported it in advance, otherwise it would have caused immeasurable losses of people and property...... Our reporter will continue to follow up on the investigation of the case......."

After reading the news, Yang Yu sat down on the sofa in the living room, and her sweat beads flowed down......

"Ding Zicheng, you are a hungry wolf! You are a dead hand! This is to put my father to death!"

Yang Yu closed his eyes, thinking about the noon news just now. She knew that this was a scene directed by Ding Zicheng.

Ding Zicheng wants to cause a bigger mining disaster in the mine, and the greater the disaster, the greater the responsibility of Yang Changqing, as the company's legal person. If Ding Shicheng's death was an accident, then the news just broadcast on the news shows that burying a large number of detonators in the 1012 mine is a deliberate mining disaster. This kind of crime is just too big.

Yang Yu has no other way now, she can only move forward, one step at a time.
