When Wan Yaochen came back, Song Qingyun simply drew a few strokes on the paper beside him.

No one could tell what she was drawing.

Wan Yaochen came back and the subsequent interrogation ended quickly.

"Xiao Wan, remind him to keep a close eye on this person." Song Qingyun warned in a low voice.

Wan Yaochen responded and ran quickly to find someone to make arrangements.

Soon, Lao Li and his team who had gone out to search came back.

Old Li looked hopeless.

Emma, ​​that taste is really... Forget it, memories are painful, just forget it.

Song Qingyun looked at the notebook that had been marinated on the table and instantly empathized with Lao Li.

She waited a moment before picking up the notebook, reading it quickly, then putting it down and picking up a pen to quickly write down a few time points.

Song Qingyun said nothing and went to Shen Weidong’s office.

"Sinking situation." Song Qingyun quickly drew a few circles.

"A few days after these time points, there were attacks near the steel mill, thefts at the cotton mill, and clashes between intruders and security guards at the machinery plant."

"I saw this when I was looking through the files in the archives. There were no casualties at the time, but everything was recorded."

The security personnel of these factories had reported to the Public Security Bureau, so Song Qingyun could see it.

Shen Weidong looked solemn, “So it seems that this incident is definitely not an accident, but may be an invasion by enemy agents.”

"For these other time points, our bureau's archives don't have any relevant records. I don't know if there's anything that hasn't been reported, or if it involves the military but has been suppressed." Song Qingyun said.

Shen Weidong stood up with the paper in his hand and said, "I'll ask the army to investigate, and then have people go to several factories to conduct in-depth investigations at the corresponding time."

Song Qingyun nodded.

"Any clues about Ruo Kui's case?"

Song Qingyun responded in a low voice, "Got it. Li Long told me what those two people looked like. I'm going to start drawing their portraits when I get back. I'll ask Li Long to confirm them after I finish the portraits."

"I doubt someone would want to kill someone to silence them during this time."

"I'll make the corresponding arrangements. You and Wei'an should go home and accompany Ruokui first. Chengwu is back. Let him come over. We need his cooperation on some things."

"Okay, let's go and get Chengwu back." Song Qingyun responded and turned to walk out.

When she reached the door, she remembered that she had run back directly while in class.

"I'll call Director Zheng."

“Okay, you can use my phone.” Shen Weidong said, turned around and walked out the door.

Song Qingyun called Zheng Xing's office at the provincial department.

The call was connected quickly.

"Weidong, how's it going? Did you find any clues?"

"Mr. Zheng, it's me, Qingyun."

"How's the baby?"

"It's a minor injury, just a little frightened." Song Qingyun said hurriedly.

"Sorry, Director Zheng, I was in a hurry at that time..."

"I understand. This is human nature. Who could have imagined that the enemy would be so arrogant?"

"You should rest at home for a few days, spend time with your children, and cooperate with Weidong and the others. I will ask other teachers from the Criminal Investigation Department to give classes to everyone." Zheng Xing said.

Song Qingyun was touched. She felt that all the leaders she met along the way were particularly good.

"Thank you, Director Zheng."

"We're family, so if you need any help, just tell Weidong. I've already told him to cooperate fully at all costs."

"The military has also been notified. This matter must be thoroughly investigated and all those shameful people hiding in the darkness must be brought out." Zheng Xing said in a deep voice.

Song Qingyun hung up the phone and took two deep breaths before going out to find Xia Weian.

The two exchanged glances and without saying much, they left the Public Security Bureau together and returned home.

Han Chengwu and Xia Ruokui were talking in the living room.

Han Chengwu held Xia Ruokui's hand the whole time. He was really scared!

Xia Ruokui: Actually, I don’t seem to be that scared anymore.

But seeing the people around her so nervous, she felt indescribably warm in her heart.

Song Qingyun told Han Chengwu that Shen Weidong asked him to go to the Public Security Bureau.

Han Chengwu gave Xia Ruokui a few more instructions before getting up and jogging to the Public Security Bureau.

After arriving at the Public Security Bureau, Shen Weidong immediately assigned Han Chengwu a task, asking him to coordinate the cooperation between the public security and the army.

The person who came to cooperate with the work from the army was a deputy regimental commander. The army took the attack on military dependents very seriously.

Even if they are not in the same military region, as long as they are military dependents, they must be protected.

No soldier can stand the thought of fighting on the front line while someone behind them is about to attack their family members.

Originally, a battalion commander was arranged, but the deputy regimental commander specially asked to come, so the leader let him come.

The handover between Han Chengwu and Deputy Commander Zhou went very smoothly.

Deputy Captain Zhou didn't say anything, he just focused on cooperation and getting it done.

Li Long was placed in a solitary detention room with no one around him.

Five police officers and five soldiers stood at the door, each of them armed with live ammunition and in a strict protective posture.

The food he ate was purchased by people arranged by the public security and the army, and was prepared personally under the supervision of the chef of the public security bureau.

Then they send it over.

It can be said that every detail has been taken care of.

Everyone Li Long comes into contact with must be strictly registered.

Including the comrades who came to bring him food, under such strict protection, no one could hurt Li Long.

However, in the fifth hour after being detained, Li Long suddenly smashed his bowl in front of the police and soldiers who were guarding him.

Everyone was startled, but quickly opened the door.

However, before the prison door was opened, Li Long cut his carotid artery with a sharp piece of porcelain.

He was already dead when the emergency doctor arrived.

When he died, he pointed his finger out the window and closed his eyes.

This change made everyone feel depressed and frustrated.

Why did Li Long suddenly commit suicide?

Everyone who came into contact with Li Long was strictly scrutinized by them.

Moreover, both the public security and the army sent people to supervise each other. Even in this situation, someone could still use certain means to force Li Long to commit suicide!

They could all see how much Li Long valued his life.

If he had not been determined to die, the explosive force that burst out at that moment would not have been enough to sever his aorta.

What means did that person use to make Li Long willing to die!

Who is it?

Shen Weidong was so angry that he smashed the porcelain cup in his hand.

Deputy Captain Zhou was also furious.

The two men took a deep breath and quickly placed all those who had come into contact with Li Long under solitary confinement, awaiting interrogation.

Han Chengwu's expression became increasingly serious...
