"But I won't protect myself! What if the killer knew I was looking for her and tried to kill me? "What should we do?" Bing-Er was scared just thinking about it.

"Don't worry, I will protect you from the shadows." She was also very worried about Bing'er's safety, so when she had time, she would definitely secretly protect her.

"You will also say that you will only protect me when you have time. Then, if someone hurts me when you have no time, what should I do?" Bing'er looked at ZhiNing with a hint of anger.

"Sihan stood up from the bed and walked behind Bing'er, putting her hands on Bing'er's shoulders." When my body is better, I will go to the General's Estate to accompany you and protect you, okay? "

Bing'er pouted, looked at Sihan and then at Zhining, then nodded reluctantly. "Fine." Amongst the three of them, she was the most suitable to be a spy in the Prime Minister's Estate.

"Don't worry, I will definitely protect you well." Zhining promised Bing'er confidently.

Bing'er smiled and nodded to Zhining.

"Now I'm going to teach you the basics of undercover. Bing-Er, from now on, you have to remember every word I said to you, okay? " Zhining looked at Bing'er seriously and asked.

Bing'er nodded seriously as well. This was not only related to her life, but also to Lu Zhao's. Now that she had two of their lives in her hands, she would definitely remember them.

"Firstly, you should not think of yourself as a spy, but as a member of the group you want to monitor. You should not deliberately probe for information you want to know about. Instead, you should inadvertently bring up these kinds of topics, and then find out what information you want from the conversations.

Second, to find the best friend of the dead, make friends with her and extract information about the dead from her.

Third, carefully observe the people and objects around you and find valuable clues from the crowd around you.

The fourth and most important point is that you are not allowed to mention your true identity to anyone. The true purpose of your visit to the Prime Minister's Estate, do you know? " ZhiNing first explained to Bing'er the things she needed to pay attention to.

Bing-Er nodded, "Understood." Naturally, she would not tell anyone about her identity.

"You have to watch everyone. You have to figure out the following. First, you have to find out who got injured on the back of his hand after Xiu-Er died."

Second, to find out where Xiu-Er's child was, and whose flesh and blood it was. Maybe the man who was involved with Xiu-Er had killed her.

"Thirdly, we have to find out why the murderer killed Xiu-Er." Zhining looked at Bing'er seriously and said.

"I see." Bing'er looked at Zhining and answered.

"Bing-Er, be careful." Sihan stepped forward and held Bing-Er's hands.

Bing'er gave Sihan a reassuring smile and said confidently, "Don't worry, you forgot that I'm an actor! A mere spy wouldn't be a problem for me. "

After leaving the Liang Household, ZhiNing sent Bing'er back to the Sky One investigation office.

When they reached the door of the detective agency, Bing-Er let out a big sigh, "So sleepy!" With her eyes half-closed, she waved to Zhining, "Goodbye."

Zhining stood there looking at Bing'er with mixed feelings. Although she was not worried about Bing'er's acting skills, there was always a chance.

In the room, the candles were lit, and Bing'er smiled happily. Grandma Lu must have been waiting for her so that she wouldn't be able to sleep.

Grandma Lu quickly opened the door and saw Bing'er standing outside. She revealed a relieved smile and said, "Young Master Liu, you've returned."

Grandma Lu's relieved smile warmed Bing'er's heart. How long had it been since she last felt maternal love? She sniffed and smiled at the landlady. "I'm back."

"Bing-Er!" Zhining, who was standing behind Bing'er, couldn't help but call out to her.

Bing'er turned around to look at Zhining. "What is it?" Could it be that there was still something Zhining didn't tell her?

"Be careful." ZhiNing faintly said to Bing'er.

Bing'er nodded to Zhining, "Don't worry, I will be very careful."

After getting Bing'er's guarantee, ZhiNing then left the Sky One Investigation Division in peace.

In the Chen Residence.

Zhining saw the Chen family guard standing at the gate from afar. Without even thinking, one could already tell that the Chen family guard was waiting for her. ZhiNing paused for a moment, then strode towards the Chen Mansion's main entrance.

Chen Jiaxuan looked at Zhining, who was slowly walking into his house, and questioned Zhining with an ice-cold voice, "You still know how to come back?" Today was the second day after the Chief Patrol Officer was injured, and she actually did not stay by his side!

"This is my home, of course I'll come back." ZhiNing did not even look at Chen Jiaxuan as she walked straight towards the door.

Seeing that Zhining did not even give him a glance, Chen Jiaxi was immediately enraged. He looked at Zhining's back and bellowed, "Stop right there!"

"What is it, Father?" Zhining stopped and asked Chen Jiawai without looking back.

Chen Jiaxuan's hands could not help but tighten into fists. He took a few steps forward and stood in front of Zhining, coldly looking at her. "What kind of attitude is this?" Do you still have a father in your eyes? "

ZhiNing looked back at him deeply, "Your daughter definitely has you in her eyes."

The Chen family's guard looked at Zhining with a livid expression. She had him in her eyes? If she had him in her eyes, she wouldn't disappear from him every now and then! With him in her eyes, she wouldn't even look at him when she spoke to him. She had him in her eyes? Who would believe it! However, now was not the time to pursue this matter. He forcefully suppressed his rage, looking at ZhiNing and questioned her coldly, "You clearly know that today is the second day for Sir Patrol Officer, and that he really needs someone to protect him, yet you didn't appear in the Southern Prefecture for an entire day. With your dereliction of duty, how can you do a good job?!"

"There are so many constables in the Southern Prefecture protecting the Chief Patrol Officer, not one of them is missing a daughter. Besides, the responsibility of the patrolman is to capture the culprit, not to protect the Chief Patrol Officer!" Zhining replied to Chen Jiaxue with a calm face.

"You!" The Chen family's guard looked angrily at Zhining but was unable to say a single word of rebuttal. Although he could not refute Zhining's words, Zhining had indeed failed in her duty today.

"No matter what, you did not go to the Southern Prefecture today. It is your fault!" Chen Jiaxuan accused Zhining.

"My daughter went to handle a case, how could she have failed her duty?" ZhiNing asked as she looked at Chen Jiaxia.

Chen Jiaxue could not help but look at Zhining in puzzlement. According to his knowledge, the entire capital had been peaceful recently. How could a case have occurred? "What case is she on?" "What case?" Chen Jia Wei looked at Zhining and asked.

"Lu Zhao's case." Zhining answered Chen Jiawei without hiding anything.

Chen Jia Wei could not help but look at Zhining with a little anger, his voice was clearly louder, "You're still investigating the Lu Zhao case?"

Zhining coldly looked back at Chen Jiaxuan, "Yes, Lu Zhao was wronged. As a police officer, of course I have to help him wash away his grievances." Isn't it the right thing to do a constable's errand for the innocent?

"Nonsense!" How could Lu Zhao's case be wrong if it was personally tried by the head of the Board of Justice? Even if Master Shang Shu was wrong, what about the evidence? How are you going to reverse the case for Lu Zhao? Not to mention that since the trial Lord Shang Shu had never made a mistake. Most importantly, how can a mere constable like you be able to win against the Minister!? "You really overestimate yourself!" Chen Jiaxuan looked at Zhining helplessly and disdainfully. A mere constable wants to fight against the Minister of Imperial Household?
