ZhiNing looked at Bing'er and said, "You're lucky, I'll let you go today." With that, she let go of Sihan's small hand and left with the guards in front of her.

"Let's go." Bing-Er naturally reached out her hand and held Sihan's hand. She couldn't help it; she looked like she was being protected.

Sihan stealthily avoided Bing-Er's hand, looking at her helplessly with a funny look, "Please, I am not a three-year-old child, and I am not a weak girl. I want you to hold my hand wherever I go." Bing'er and ZhiNing's protection had given her goosebumps.

Bing-Er smiled with satisfaction and walked forward. It seemed that Sihan had returned from the past. She was no longer as delicate as she was when she came here.

"Hey, where are you going?" Sihan stood on the spot looking at Bing'er's back and asked.

Bing'er didn't even turn her head, "The restaurant."

Sihan couldn't help but smile and ran after Bing'er with her complicated skirt. "Wait for me!" The ancient dress was simply too complicated. If she hadn't promised her 'father' that she would be a girl from a noble family, she would have started playing around in men's clothes like Bing-Er.

"Didn't you say that you don't need us to take care of you?"

"But I didn't say I wouldn't let you wait for me."

After eating and drinking to her heart's content, Bing'er returned to her shop, the private detective agency.

The detective agency she opened was funded by Sihan. Others used to have brothels as princesses when they traveled to ancient times, but she was an orphan, a penniless orphan. Fortunately, Sihan had helped her open a detective agency, though this dynasty did not know what a private detective was.

ZhiNing hurriedly followed the guard to another street, and saw that there was definitely a luxurious and noble carriage parked in the middle of the street. An old woman fell on the ground in front of the carriage and kept kowtowing to the carriage, "Sir, please avenge this woman's son, this woman's son is wrongly accused. "My lord, I beg you to avenge my wife's son."

Who else could this old woman be if not Lu Zhao's mother?

ZhiNing wanted to step forward and help the old woman up, but the guard in front of her grabbed her arm. "Constable Chen, the patron will be here soon. I have to go back quickly, otherwise, the lord won't be happy."

Displeased, Zhizi shook off the constable's hand that was tugging at her arm and walked towards the old woman. Unexpectedly, she had only taken a few steps when she heard a lazy voice from inside the carriage. "You want me to overturn the case for you?"

The old woman raised her bloody head and looked excitedly at the carriage, "Milord, the son of this humble servant is the Prime Minister's personal guard. The old woman lifted her bloody head and looked excitedly at the carriage," Milord, the son of this humble servant is the Prime Minister's personal guard. As she spoke, the old woman kowtowed to the people in the carriage.

"Oh? "So Lu Zhao is your son!" A surprised voice came from the carriage.

"Yes, Lu Zhao is really the son of this humble woman, the son of this great woman is truly wronged, begging the lord to uphold justice for the son of this humble woman!" The old lady did not care about her bleeding forehead as she looked excitedly at the carriage.

There was a period of silence in the carriage, with Zhining standing at the side, waiting for the answer of the people in the carriage. She hoped that someone would help the old woman to reverse the case and reinvestigate the murder case of the Prime Minister's Estate. To prevent the innocent from being falsely accused.

After a long while, the person in the carriage finally opened his mouth, "It's said that the case was personally tried by the Minister of Justice Zhuang Shangcheng, and enough evidence to prove that Lu Zhao was the culprit."

"Yes, but my lord, Lu Zhao is innocent. That night, because the woman's body wasn't well, Lu Zhao stayed at home to take care of her, never going out at all. How could he have gone out to kill someone in the Hai hour?" The old woman knelt on the ground and answered respectfully.

"At home all night?" The people in the carriage questioned.

"Yes." The old woman answered with certainty.

"Does anyone else know about this?" The person in the carriage continued to ask.

"No, Lu Zhao has always been at home and hasn't gone out. That's why no one knows that Lu Zhao has always been at home." The old woman answered truthfully.

"In other words, apart from you, no one else can prove that Lu Zhao was at home all night?" The people in the carriage questioned coldly.

The old woman glanced at the carriage, then lowered her head and replied respectfully, "Yes."
