Chu Zhenhuan did not hide anything from Zhang Yu. Qin Yu also knew that Zhang Yu was someone Chu Zhenhuan trusted very much. So, after Chu Zhenhuan finished speaking, Qin Yu added: "Our Integrity Inspection Bureau is now secretly monitoring that Brother Ming. We have not found any close contact with anyone. In addition, Wang Ci really got the internship confirmation letter given to him by Zhenhai Medical University today, and he can go to the Medical University for internship tomorrow. However, we have not found out yet. Who approved Wang Ci to intern at the Medical University for internship. Of course, if you really want to investigate, you are not unable to find out. Just investigate rashly, it is very likely that you will be alerting the snake and let the big fish slip away."

"So that's it..." Zhang Yu nodded and said, "I accidentally discovered that the person who helped Wang Ci operate the stock was Mr. Cao from Guangcai Investment Company on the 20th floor of Double Star Building. This person is simply indifferent to his work, so that Wang Ci's source of income can make sense."

"There is such a thing..." Qin Yu took a deep breath and then looked at Chu Zhenhuan.

Chu Zhenhuan was also shocked, thought for a while, and said, "What is the origin of this Cao? Can you find out?"

"The time is too short, and it has not been found yet. But I can be sure that there must be a big fish behind this person... because he had already eaten stocks of Wudang Group, Changxing Hotel Group, Changjiang Tourism Group, and Feihua Decoration Group a long time ago, so that he could make a fortune by making a big fortune and help Wang Ci make five million in the stock market at once. However, there must be not many people who can know about the conspiracy of the Qi family. Mr. Cao can understand everything. Without a sure source of information, it would be impossible to accomplish this." Zhang Yu said seriously.

"It has something to do with the Qi family..." Chu Zhenhuan pondered.

"There is no conclusive evidence to prove this yet. It is too difficult to say whether it is the Qi family..." Zhang Yu said with no certainty.

"It really needs to be true evidence..." Chu Zhenhuan nodded slightly.

Qin Yu, who was sitting on the side, said, "Director Chu, look at us now and we will arrest Mr. Cao directly. Can we ask for some things..."

"It is easy to catch people, but it will move your whole body with one move... When he is captured, the others will definitely get news. If they all run away..." Chu Zhenhuan shook his head slightly, he looked at Zhang Yu and said, "Xiao Yu, how did you find out these news?"

"I went to the Double Star Building to work as a night security guard yesterday. When I went to patrol on the 20th floor, I accidentally heard it..." Speaking of this, Zhang Yu suddenly remembered the notepad I saw at night, and he continued: "By the way, I saw a notepad with Wang Ci's name last night. On that notebook, I still remember the names of many people. But the things recorded in this notepad are very strange, and I can't understand what it means at all."

"Oh?" Chu Zhenhuan hesitated for a moment and said, "What are you writing?"

"The ones written on it are dates and numbers written on it are afterwards. Some people have a long time, while others have a short time. Wang Ci's record is at the end, and the time starts in November. I remember that the initial ones written on it was 0.2, 0.2, 0.5, and then it becomes 10, 1, and the last one, which is yesterday's record, is 50."

"50?" Chu Zhenhuan pondered and said, "As far as I know, the money in the stock account that Brother Ming gave to Wang Ci seems to be 5 million."

As soon as he said this, Song Feng, who was sitting next to Zhang Yu, immediately shouted: "It's the account book!"

"That's right! It's very likely the account book!" Qin Yu also said.

"Open book?" Zhang Yu was stunned for a moment and said, "This will be an account book..."

Chu Zhenhuan nodded and said, "The account book will involve very important interests. It can also be said that it is a kind of evidence that can be used to restrict the people in the account book. Because if you do bribes, especially by using this method of stock trading, the source of the property can be explained very clearly. Only those who know the account book know how to operate can you explain the bribery clearly. Wang Ci's last account was 50. In fact, to put it bluntly, it is to use 100,000 as a unit, and 50 is equivalent to 5 million. What you mentioned before should be 20,000 and 50,000. You just said that one of them is 10, which should be 1 million, which can be roughly equal to the value of a Maserati. Of course, the difference is the same as that."

"I think so too..." Song Feng said.

Qin Yu was so energetic that he said, "Have you brought this account book out?"

"I didn't dare to bring it out. If the Cao surnamed today was discovered, wouldn't it be alarmed? And at that time, I didn't know what it was." Zhang Yu said.

"It is indeed not suitable to bring it out." Chu Zhenhuan said: "However, Xiaoyu, you can copy this account book. The people in the account book must have been bribed. If they can be beaten up, the mastermind behind them will probably not be able to escape even if they want to."

"This is easy to deal with. The account book is in his office cabinet. I'll go there again and copy the things." Zhang Yu said confidently.

"I really didn't expect that this case would be very troublesome, and it would take at least a considerable period of time. As a result, it was a coincidence that you accidentally found an important clue. It seems that it was exactly the same as the saying that good and evil will be rewarded in the end, but it's just that it's too late and early." Chu Zhenhuan said with emotion.

If you want to copy it, it is very easy in this day and age. You just need to take a picture with your mobile phone, and everything can be solved, saving time and effort.

Qin Yu looked at Chu Zhenhuan again and said, "Director Chu, I think in addition to copying the account book, someone needs to be sent to investigate the person named Cao."

"We must investigate him... but I think we can't let our people do it this time..." Chu Zhenhuan said.

"If our people don't let them do it, then who will do it?" Qin Yu wondered.

"In the investigation of Wang Ci, I actually encountered other people installing monitors in his car. The man quickly turned off the monitors, which made us lose the signal of tracing. From this, we can see that the other party not only has strong anti-reconnaissance ability, but also has a very good understanding of our Integrity Inspection Bureau. I am worried now that there will be their people in our house. So..." Speaking of this, Chu Zhenhuan looked at Song Feng and said, "Captain Song, I want to leave it to you to investigate Mr. Cao's affairs."

"No problem!" Song Feng agreed immediately.

"You are the captain of the criminal police team, and you must be experienced in this kind of investigation. However, I still want to remind you that it is of great importance and you must not leak information in this matter. The person sent to the investigation must be trustworthy and must not be discovered by the target!" Chu Zhenhuan said solemnly.
