No wonder Dong Zheng was a little confused. The Red Party criminals secretly escorted to Shanghai from Nanjing were more or less found to have some connection with Shanghai, so they were escorted to Shanghai for secret interrogation.

This person was just a Red Party arrested at the Red Party Xiaguan Transportation Station. On the surface, this person had no connection with Shanghai.

"His glasses." Yuan Ziren showed a complacent look.

"Glasses?" Dong Zhengguo was slightly surprised.

Yuan Ziren opened the drawer and handed a small round glasses to Dong Zhengguo.

This is an old glasses, which are seriously worn and have a broken leg and are wrapped with tape.

"Here." Yuan Ziren pointed, "This is Hengdali's glasses on Nanjing Road, with marks on them."

Dong Zhengguo looked carefully and saw the English name of ‘hopebrother’s’, which is the logo of Hendale’s glasses.

"Based on this alone, I'll say that this person is related to Shanghai..." Dong Zhengguo frowned slightly, "If I remember correctly, there should be Hendali's shop in Nanjing."

...

"Brother Dong, these glasses are very old." Yuan Ziren smiled slightly.

Dong Zhengguo was shocked and nodded, "Brother Yuan is indeed meticulous."

The Hengdali Glasses Store in Nanjing has only been newly opened in the past year. Judging from the wear level of this person's glasses, it has been used for at least two or three years, so this pair of glasses can only be configured in the Hengdali Glasses Store in Shanghai.

"Maybe, Brother Yuan, you are catching a big fish." Dong Zhengguo glanced at Shang Jiayuan who had fainted, thinking about it.

"It's not known whether it's a big fish." Yuan Ziren shook his head, "But, this mouth is indeed hard enough."

...

In the evening.

Cao Yu left the office, stretched and went downstairs.

"Team leader Cao, go home."

"A bachelor, what's the house?" Cao Yu yawned, "Go to Xianlesi to dance."

"Team leader Cao really knows how to enjoy it."

"Go and go, just enjoy dancing?" Cao Yu laughed, "You guy is also a man who has never enjoyed his happiness."

"Team leader." Xie Xiaqing came up and nodded at Fan Jixian, who was in the Operations Division beside Cao Yu.

"Team Leader Cao, you are busy." Fan Jixian said.

"I'll be a party the next day, so I'll have a few cups together." Cao Yu nodded and said.

Seeing Fan Jixian waved his hand to respond, Cao Yu then winked at his subordinates.

The two walked in the yard, and there was no one else around.

"Tell me." Cao Yu said.

"Guo Huaijing is not at home." Xie Xiaqing said, "This guy hasn't been to the headquarters for two or three days."

"Are it two or three days?" Cao Yu asked.

"It should be two and a half days." Xie Xiaqing said.

"I received my salary yesterday, but Guo Huaijing didn't come either?" Cao Yu asked with a frown.

"No." Xie Xiaqing shook his head, "I asked, no one has seen him."

"You go to the General Affairs Office to check the salary statement and see if Guo Huaijing's signature is on it." Cao Yu whispered.

"Team leader, do you suspect Guo Huaijing has any problems?" Xie Xiaqing handed a cigarette to Cao Yu and asked carefully.

"If you ask you to check, just check it, there is not so much nonsense." Cao Yu glared at Xie Xiaqing.

"clear."

...

Half an hour later, Xie Xiaqing appeared in Li Cuiqun's office.

"Cao Yu is secretly investigating Guo Huaijing?" Li Cuiqun looked up at Xie Xiaqing.

"Yes, Director."

"Did Cao Yu say why he should investigate Guo Huaijing?" Li Cuiqun asked again.

"No." Xie Xiaqing shook his head, "Team Leader Cao only asked me to check Guo Huaijing, and nothing else said."

"Did Guo Huaijing come to receive his salary yesterday?" Li Cuiqun asked.

"I've received it, I have a signature." Xie Xiaqing said, "However, my subordinates looked at the signature carefully. The signature should be signed by the agent, not Guo Huaijing's own signature."

"Hmm?" Li Cuiqun glanced at Xie Xiaqing, then rang the bell, "Come here for the salary and receive the detailed list."

Soon, Zhang Lu personally brought the detailed list from the General Affairs Office. He looked carefully and found that Guo Huaijing's signature was indeed signed by the agent.

It is not surprising that the agents at the agent headquarters sign on their behalf when they receive their salary. The agents at the agent headquarters do not work regularly and often ask someone to receive their salary. Some agents are not literate, and the General Affairs Office often helps sign and record accounts.

However, Li Cuiqun soon noticed that on the previous salary signing table on the detailed list, Guo Huaijing signed the salary himself, which shows that this person has the habit of receiving the salary himself and signing it in person, and this time is the exception.

This attracted Li Cuiqun's attention.

...

"What are Guo Huaijing doing these days?" Li Cuiqun asked.

"I don't know." Xie Xiaqing shook his head. He thought for a while and said, "Section Chief Dong has often been away from the headquarters these days. I guess he is following Section Chief Dong to work on the matter."

"You mean, Dong Zhengguo hasn't come to the headquarters these days?" Li Cuiqun asked immediately.

"I don't know if I have come or not, but I haven't seen you." Xie Xiaqing said.

"You go to see Cao Yu later and report to him about getting a salary and signing." Li Cuiqun said in thought, "In this way, you can find a way to find out from Cao Yu and see why he investigated Guo Huaijing."

"I understand."

After Xie Xiaqing went out, Li Cuiqun walked out from behind the desk. He stood at the window and looked out the window and fell into deep thought.

"Zhang Lu."

"gentlemen."

"Do you know what Dong Zhengguo has been busy with these days?" he asked.

"I don't know." Zhang Lu shook his head and asked, "Sir, do you want me to check it out?"

"Go." Li Cuiqun nodded.

Here, Xie Xiaqing found Cao Yu and reported to him the results of the investigation and signature of the salary.

"The signing?" Cao Yu frowned slightly.

"Yes, team leader."

"This guy has always been the most active when paying wages, it's weird." Cao Yu murmured.

"Team leader."

"Um?"

"Is there anything wrong with Guo Huaijing?" Xie Xiaqing asked again.

Cao Yu winked.

Xie Xiaqing hurriedly closed the door.

...

"On the day Liu Wuliu died, someone saw a person who looked like Guo Huaijing appeared nearby." Cao Yu said with a serious expression.

"The team leader suspected Guo Huaijing..." Xie Xiaqing's face changed slightly.

The team leader mentioned Liu Wuliu, who was a spy who invaded the agents' headquarters of the Red Party. He was discovered by the agents' headquarters and sent someone to arrest him secretly, Liu Wuliu had already committed suicide by taking poison before breaking the door.

This incident caused Li Cuiqun to be furious, believing that there was a leak of news. The secret agent headquarters had identified the matter, but found nothing.

"It's hard to say." Cao Yu shook his head with a serious expression, "It's about colleagues. You know what I know about this, just investigate it secretly."

"I understand."

Seeing Xie Xiaqing leave, Cao Yu narrowed his eyes. As he expected, Xie Xiaqing should have secretly reported the matter to Li Cuiqun.

He had long discovered that Xie Xiaqing was actually Zhang Lu's man, and deliberately pretended not to know.

He wanted to attract Li Cuiqun's attention to Dong Zhengguo and lead Li Cuiqun into the trap, but he could not throw Dong Zhengguo out directly. This was too obvious, so he chose to start with Guo Huaijing, a subordinate of Dong Zhengguo.

A cigarette was lit, and Cao Yu's eyes were deep and solemn.

...

French Concession, Baier Road.

Yanqingli, No. 389.

Cheng Qianfan got out of the car and said to Li Hao, "You go home and tell Ruolan, just say I'm busy with official business tonight, rest in the police room, and I won't go home."

"Yes, Brother Fan." Li Hao nodded, "Brothers..."
