It turned out that Wu Aiguo was getting anxious because Su He and his team hadn't found the murderer after several days. He also suspected Zheng Jiabao and didn't understand why the police weren't arresting him. Was it because they wanted to protect him?

So he simply called the military.

After the military learned of this, they arranged for the Armed Forces Department to work with the Municipal Public Security Bureau to arrest Zheng Jiabao.

Upon learning this, Su He and the others immediately returned to the Municipal Public Security Bureau.

The officers who arrested Zheng Jiabao were Zhou Yan and other ordinary police officers from the municipal bureau.

As soon as Su He saw them, she asked, "What's going on? Isn't this case our responsibility? Why are you leading the arrests?"

Zhou Yan smiled helplessly at her, "We're just following orders from above. We don't know the specifics, but we've heard that the Armed Forces Department will be interrogating the suspect with us."

Su He frowned upon hearing this; this was far too presumptuous of her to do things her way.

Just as I was about to say something, I saw Captain Chen coming over.

Upon seeing Su He, he said directly, "I already know the specifics. It was pressure from the military. How's your investigation going? If you haven't found the suspect yet, then the armed forces department will have to take charge."

Everyone felt quite aggrieved after hearing this.

Su He frowned and looked at Qi Yang, who nodded at her.

So Su He thought for a moment and said, "We do have someone we suspect, but it's not Zheng Jiabao. However, we have too little evidence at the moment, and this person's identity is special. Without particularly clear evidence, it's not easy to arrest him. So we originally wanted to wait and see."

Upon hearing this, Captain Chen immediately asked, "Who is it?"

"Song Yuzhu"

Captain Chen had obviously seen the case files, and he was taken aback when he heard her name.

After a moment of silence, he finally spoke: "Arrest him!"

"Hmm?" Su He looked at him in confusion.

Captain Chen said directly, "Since you have suspicions, then arrest them. You must find the murderer before the Armed Forces Department does, otherwise the impact will be very bad, and our Criminal Investigation Brigade will be laughed at."

Upon hearing this, Su He and the others realized the seriousness of the situation.

He took a deep breath. "Okay, let's arrest them."

So the others immediately took action, leaving Zhou Yan standing awkwardly in place. Finally, he sighed, shook his head, and left.

After Su He and the others came out, they went straight to the Wu family's house. When they arrived, Wu Aiguo was not at home, only Song Yuzhu was there, which made it convenient for them to move around.

Song Yuzhu was surprised to see them; clearly, she knew about Zheng Jiabao's arrest.

"May I ask what brings you officers here today?"

Su He stared at her intently and said, "I'm here to arrest you!"

"Wh...what? Arrest me? Why are you arresting me?"

"You should know, right?" Su He stared at her without blinking. "You should have guessed why we came to arrest you, right?"

Song Yuzhu's expression tensed for a moment, then she quickly lowered her head and shook it. "I don't know why you're arresting me. I'm not going. I want to wait for my husband to come back. You can't arrest me!"

Seeing this, Su He didn't say much to her, but said directly, "Are you going to leave on your own? Or are you going to be handcuffed and taken away by us? Of course, you can make a scene, and it won't affect us if someone sees you."

Hearing her say that, Song Yuzhu fell silent. She clearly knew she couldn't resist, and finally could only say, "...Then I'll go with you."

Su He nodded, then looked at Qi Yang and said, "Take Wang Jun to the station for questioning as well."

Qi Yang nodded, "Okay, I'll go directly to his factory to find him."

Su He noticed that when she mentioned Wang Jun, Song Yuzhu's face stiffened for a moment.

She seemed thoughtful, and without saying much more, she prepared to leave with her.
