Chapter 231 Oriental Chess Club
After understanding the Director's true intention, Chu Lingyun could only give his all to this case.
No wonder he was given such great power. The director must be completely disappointed with the Hangzhou Station, otherwise he would not let a team leader command the stationmaster.
"Yes, I'll get it for you."
Cai Zhengru responded hurriedly. He had already expected that Chu Lingyun wanted to see the files. Since someone was in charge of solving the case, it was impossible for them to just listen to his description. Many things still needed to be recorded in more detailed text.
The file was not thick, and Cai Zhengru was not sure of the exact time when Ren Cheng was instigated by the Japanese, but he had a rough guess.
This period should not exceed half a year. Half a year ago, their investigation on the Japanese was going smoothly, and they even caught two traitors and a Japanese spy at that time.
Nothing went well in dealing with the Japanese over the past six months. Stationmaster Cai had doubts before the order from headquarters came down. After the order arrived, he used false intelligence to finally find out Ren Cheng.
In his opinion, unknown enemies are the most terrifying. After the traitor was exposed, he wanted to use Ren Cheng to provide false information to the Japanese, so as to capture more Japanese spies at one time, and then capture Ren Cheng.
Use the captured Japanese spies to make up for the losses caused by the leak of intelligence.
The ideal is very good, but the reality gave him a heavy blow.
The Japanese spy was not caught and Ren Cheng ran away again. All his efforts were in vain, which put him in a very passive position. If it were not for Secretary Qi's help, he would probably have been caught and taken back to headquarters.
"Stationmaster Cai, let me first look at the specific circumstances of the case."
Chu Lingyun took the file. The case was important. A lot of time had been wasted at the Hangzhou station, and the time ahead was even more urgent. The traitor must be found as soon as possible.
Although the Director did not give him a time limit to solve the case, he was very aware of the pressure he was under at the time and he had to catch the escaped traitor as soon as possible.
"You look first."
Cai Ruzheng nodded quickly, while Zhu Qingze sat calmly beside him. His mission was to protect Chu Lingyun, not to solve the case.
This time, he was not given any new instructions from his superiors, which meant that his mission had not changed. Chu Lingyun would solve the case and he would be his bodyguard. If he was used in the process of solving the case, he could also get some credit.
Who would have thought that there would be cases to handle even in Hangzhou? It was worth it to come here in person this time.
The file does not contain much content and is not complicated.
Cai Zhengru, the stationmaster, was quite capable, using four different pieces of false intelligence to successfully trick the traitor into revealing himself. Unfortunately, upon discovering the traitor, he did not immediately arrest him. Instead, greed took over, hoping to use him as a pawn to lure the Japanese into the trap.
Cai Zhengru wanted to be a chess player, but his chess skills were not good enough. His chess pieces ran out and overturned the chessboard.
Ren Cheng is the deputy team leader of the intelligence group. This deputy team leader was promoted by Cai Zhengru himself. No matter which branch station, the intelligence group is very important and is basically directly controlled by the station chief.
The leader and deputy leader of the Hangzhou station intelligence team are all Cai Zhengru's confidants.
As the deputy head of the intelligence team, Ren Cheng knew many secrets of the Hangzhou Station, and it goes without saying that these secrets were definitely known to the Japanese.
At present, Ren Cheng has not been brought to justice, and it is not clear what specific information he has leaked.
Just looking at the files, the case is not complicated. Ren Cheng was instigated by the Japanese and became a traitor in the Hangzhou Station. Cai Zhengru found him, but he escaped.
However, many details in the file are not clear and are vague.
"Stationmaster Cai, you only searched Ren Cheng's home and checked his hometown?"
Chu Lingyun asked softly after closing the file. Cai Zheng was stunned for a moment, then nodded immediately, "That's right, it's a pity he's not in his hometown, and we didn't find anything useful in his house."
Ren Cheng is from Jiaxing, and his hometown is very close to Hangzhou. Eighty percent of the people at Hangzhou Station are from Zhejiang Province.
When Ren Cheng escaped, he took away all the valuables in his home. He did not return to his hometown. There were not many people in his hometown, only his old mother, and now his mother is nowhere to be found.
Chu Lingyun shook his head secretly, thinking that Stationmaster Cai’s investigation was too one-sided.
Since it has been confirmed that Ren Cheng is a traitor, everything about him must be investigated thoroughly. What's the point of just searching his residence and hometown? Ren Cheng understands the consequences of what he did being discovered, so how could he not be on guard?
"Stationmaster Cai, I want to go to all the places Ren Cheng has been to before. Can you do it?"
The case was important, so Chu Lingyun couldn't continue to be polite and spoke directly to Cai Zhengru.
"Everywhere you've been?"
Cai Zhengru's eyes widened. Ren Cheng was the deputy head of the intelligence team in the station and a senior executive. No one had suspected him before, and no one had tracked him. How could they know where he had been?
Just by looking at his expression, Chu Lingyun knew that he simply couldn't do it. He could only sigh, "If you can't find out all the places he's been to, then go find out where he's been. The more detailed the better. Don't just check inside the station. Send people out and use spies. There's bound to be someone you know who has seen him."
"I understand. I'll arrange for someone to check right away."
Cai Zhengru nodded immediately, picked up the phone on the table and called his subordinates, asking them to send people out and conduct the investigation according to Chu Lingyun's requirements.
Checking whereabouts was a necessary investigation. After Cai Zhengru returned, Chu Lingyun asked again: "When was Ren Cheng's mother taken away? Who took her away? Was it Ren Cheng himself?"
Cai Zhengru had checked Ren Cheng's hometown and found that it was not far away and he could go back and forth in one day.
But no matter how close it was, it was impossible for an old woman to run away without any notification. The most likely possibility was that Ren Cheng himself, or someone else Ren Cheng found, went to pick up his mother.
Ren Cheng is not stupid. Once his affairs are exposed, Hangzhou Station will definitely find his hometown, and then his mother will be in danger.
"He was taken away half a month ago. I don't know who took him away. I'll ask again."
Cai Zhengru shook his head and replied that the person he sent to Ren Cheng's hometown had reported that Ren Cheng's mother had disappeared half a month ago.
Half a month ago, he had just discovered that Ren Cheng was a traitor. Cai Zhengru felt a little regretful at that time. Since he had confirmed that Ren Cheng was a traitor, why didn't he think of controlling his family in advance?
"Ask first."
Chu Lingyun frowned. How did the Hangzhou station investigate the case?
He doesn't even know who took away the traitor mother. If his men go to investigate and don't ask clearly, they will definitely be scolded.
But since Cai Zhengru was not his subordinate and was the stationmaster, he couldn't scold him directly.
Cai Zhengru called his operations team leader. He personally led the team to Ren Cheng's hometown. After asking a few questions, he hung up the phone in a hurry.
"Team Leader Chu, my men were clueless. They only asked if Ren Cheng's mother was home and when he left. They also asked if it was someone Ren Cheng picked up. But the neighbors didn't see Ren Cheng's mother leave and don't know the situation. I've ordered them to go to Ren Cheng's hometown immediately to verify these details again."
As expected, nothing was found. Chu Lingyun sighed slightly. With the working style of Hangzhou Station, he would probably have to rely more on his own people for this case.
Fortunately, Zhu Qing came, so he was not left without manpower.
The ten people brought by Shen Hanwen are definitely not enough to solve such a case.
"Have them investigate as quickly as possible. I also need all of Ren Cheng's phone records at home and in the office, as well as his daily entry and exit records. Please ask the security guard for details."
These are things that are not in the files, so Chu Lingyun can only ask Cai Zheng for them.
"Okay, no problem."
Cai Ruzhi agreed without hesitation, but he didn't really care about it.
Ren Cheng is a traitor. Even if he contacted the Japanese, how could he use his own phone? Wouldn't that leave himself a loophole? In his opinion, there was no need to check the phone at all.
But he is not the one leading the case now, so he can only obey all Chu Lingyun's orders. Chu Lingyun is holding the imperial sword, and he can execute everyone in the entire Hangzhou station, including him, the stationmaster, without reporting to the emperor later.
Even if you don't understand, you can only obey.
These things needed to be investigated immediately, and it would take time to find them out. Chu Lingyun did not intend to waste time, so he asked Cai Zhengru to call a few people from the Intelligence Department to question them.
The place for inquiry was not in Cai Ruru's office, but in another office.
The first person to come in was Fang Hai, the head of the Hangzhou station intelligence team. Chu Lingyun didn't let anyone else follow him. There were only the two of them in the office, and they were sitting on the sofa talking.
This will avoid giving them the feeling of being interrogated.
"Team Leader Fang, I'm sorry, this case is important, and I need to ask you for some information. Please forgive me."
Chu Lingyun took a piece of paper and wrote down the content of the questions himself.
"Team Leader Chu, you're too polite. Feel free to ask anything you want to know."
Fang Hai replied hurriedly. He did not dare to be arrogant towards Chu Lingyun. Although they were at the same level, Chu Lingyun was the team leader of the headquarters and was naturally half a level higher than him.
What's more, Chu Lingyun has great power this time. Even the stationmaster has to obey his orders, let alone them.
"What are Ren Cheng's hobbies? Where do he often go? Has he ever taken the initiative to inquire about confidential information?"
In order to save time, Chu Lingyun asked several questions at once.
"Ren Cheng is usually quite diligent. His hobby is playing chess. When he has nothing to do, he likes to play chess with others. Many people in the station have played against him, but none of them are as good as him."
"I don't know where he often goes, but there's one place he definitely goes to often: the Oriental Chess Club on Wanhua Road."
"Ren Cheng usually keeps a low profile. I haven't seen him actively seeking confidential information. However, as the deputy team leader, many things are kept secret from him, so he knows quite a bit."
Fang Hai answered quickly, and Chu Lingyun wrote down his hobbies and the Oriental Chess Club.
Ren Cheng likes to play Go. There is a Go set in his office and many people know about his hobby.
"Has he shown any abnormalities in the past six months?"
Chu Lingyun continued to ask. Fang Hai thought for a moment and then said, "I haven't seen anything wrong with him. It's just that people from the chess club occasionally call him and ask him to play chess. He even called me once during a meeting."
The chess club often contacts Ren Cheng? This is a clue, Chu Lingyun will write it down first.
"Anything else?"
Fang Hai shook his head and said, "No, he's usually very self-disciplined and hasn't done anything else besides playing chess."
"Where are his family?"
Ren Cheng has a wife and two children, a son and a daughter. His family disappeared with him and is now missing.
"His wife is educated, well-educated, and quite pretty. Many people at the station envy him for marrying such a good wife. However, his wife has never been to the station. I have only seen his wife and children occasionally when I visited his home."
"Does his wife have a job?" Chu Lingyun asked immediately.
"No, the two children are young, and Ren Cheng's mother is in her hometown. She is not in good health and cannot help them. His wife is at home alone taking care of the children."
Chu Lingyun asked a few more questions, all about Ren Cheng's daily life, and then sent Fang Hai out.
The three captains of the intelligence team were also called over by Chu Lingyun and questioned one by one.
Their answers were similar to Fang Hai's. In their impression, Ren Cheng was relatively low-key and had no other activities except his hobby of playing chess.
He never goes to places like casinos and Lichunyuan.
No one had ever seen him smoke opium. In the eyes of many people, he was a good man, hardworking and family-oriented. No one would have thought that he would be instigated by the Japanese and become a traitor.
After asking clearly, Chu Lingyun returned to Cai Zhengru's office.
"The phone records for Ren Cheng's office have been found, as well as his home. They're all here."
When Cai Zheng saw Chu Lingyun, he immediately took out a copy of the phone records.
Ren Cheng made a lot of phone calls. Although the records only cover half a year, they are densely packed to more than twenty pages.
"Stationmaster Cai, please help me check off all the phone numbers in the station."
Ren Cheng is the deputy team leader of the Hangzhou station. There must be many internal calls to him. There is no need to check these. Even if we need to check, it is not the time to do so.
Cai Zhengru called a few people to help, and immediately more than half of the phone numbers in the record were gone.
This shows that the people who usually have main contact with Ren Cheng are still the people in the station.
For the next phone numbers, Chu Lingyun asked Zhu Qing and Shen Hanwen to help him pick out the repeated ones first, and then select the numbers with the most repetitions.
The phone records were quickly sorted out. Excluding his home phone number, the number that ranked first had called Ren Cheng 23 times.
The second digit occurs only 7 times, and this number is three times the second digit.
"Stationmaster Cai, could you please immediately have someone find out where these three phone numbers belong?"
This is Hangzhou, not Nanjing, and people from the Hangzhou station are needed to check these things.
The investigation results of the three phone numbers came out quickly. The number ranked first belonged to the Oriental Chess Club. The chess club did call Ren Cheng frequently, and Cai Zhengru was not surprised by this result.
He also knew Ren Cheng's hobby. Ren Cheng spent half of his time every month in this chess club, and Ren Cheng was familiar with many people in the chess club.
In his opinion, there is nothing wrong with a hobby like playing chess, and it is normal to go to the chess club and communicate with people more often.
Playing chess is an elegant sport. Cai Zhengru also knows how to play it, but his chess skills are average. He even envied Ren Cheng's chess level.
Oriental Chess Club, Chu Lingyun narrowed his eyes.
It is normal for the chess club to contact old customers. People in the club often challenge masters. Ren Cheng is very good at chess. To outsiders, there is nothing wrong with calling him to challenge him.
Cai Zhengru never doubted the chess club.
If Ren Cheng had not betrayed, all this would be normal, but he did. The fact that the chess club called him so many times in half a year is suspicious, and these calls need to be investigated in detail.
There is also the chess club, which also needs to be investigated.
