The crown prince and the Prince Jin felt a sense of danger upon learning about this. Yuwen Fei had been doted on by the emperor before, but because he insisted on taking Mr. Dong Li as his master when he was 14 years old, and because his personality changed greatly after returning to the capital, the emperor gradually let them go.

Of the two people who were currently at the heart of the storm in the capital, one of them had just come out of the palace and gone to the wine shop to get drunk, and the other was bored out of boredom, playing with the wild cat while waiting for Ran Mei to pack up her things before leaving the palace. Because she had to investigate Ping Yang's case, it was not convenient for him to go in and out of the palace, so Huai Jin would stay at Grand Princess Mansion for the time being.

The empress dowager muttered to herself for a moment before saying, "This Zhu Yu does remind Wailing Home of an old friend. Wailing Home heard that she is now working for Marquis de Vobo's Mansion and her name is Lv He, if you see her, bring her to the palace."

Just as he walked to the entrance of Kangshou Lane's alleyway, Huai Jin smelled a sweet fragrance pervading the surrounding air. Before this, Huai Jin had also understood this Kangshou Lane.

The memory's rouge shop was located at the corner of the Kangshou Lane and had two large shops surrounding it. The memory was different from other rouge shops, and took the high-end route. At the time, there was only one box of rouge in each store, and other than that, it could also be customized personally according to the customer's request.

The moment Huai Jin stepped into the memory, a thirteen or fourteen-year-old girl came out from behind, bowed to Huai Jin, and respectfully stood to the side. Huai Jin looked around, and saw that there were a few noble women who were also picking rouge. Each of them was accompanied by a young lady from the memory, and they did not say much when they were by their customers' side.

After looking around, Huai Jin put down the box of rouge in her hand and said: "I looked around once, but I didn't find anything that really suits me. I heard that your memory can customize it, is that true?"

The little girl nodded and respectfully said, "Miss, please follow me."

Huai Jin followed behind her as they passed through the hall of memory and arrived at the backyard.

The backyard of the memory was like a private room in a restaurant. There were a total of two floors, and each floor had four rooms. The closed doors meant that there were already guests inside.

The little girl brought Huai Jin to a room in the backroom on the second floor and said: "Please wait, Miss." She then turned around and closed the door.

Huai Jin sat in the room waiting for a moment, when a knock came from the door, Huai Jin asked for people to come in.

The door was opened by someone. Huai Jin looked up and saw a beautiful woman with a waist entering the room. When the woman entered, she closed the door with her hands and hooked up the hair at her temples. Her body swayed as she saluted Huai Jin.

"Dan Hong greets young master."

Although the person in front of him was not an absolute beauty, but the aura around her was extremely good. She was charming yet not ordinary, and from the looks of it, she should be the owner of the memory. To be able to complete memory's business as it is now, there must be some people who are capable of doing so. He looked up to her and said in a clear voice, "I want a list of all the people in the capital who have dealings with Princess Ping Yang and her consort, as well as related information."

The memory was in the business of a noble lady in the capital, so she might not be proficient in small rumors, but in regards to the changes in the imperial court and the matters in the circle of nobles, even the slightest movement would not be able to hide from the eyes of the memory. Therefore, before Huai Jin even arrived and found out that the Emperor wanted Huai Jin to investigate this case, Dan Hong had already prepared the information beforehand.

Huai Jin looked at the pile of information in front of him and gave him a deep look before lowering her head and flipping through it.

The information that Dan Hong sent over was very detailed, and could be said to be related to the two of them.

After Huai Jin finished looking through the important things in front of him, she kept some of them in her bosom. She stopped looking through the rest and returned the items back to their original state.

Then, he took out a pen and paper to write down a prescription for rouge and gave it to Dan Hong. His tone no longer contained the admiration from before, and indifferently said: "Since you are here to buy rouge, let us make a box based on this recipe."

"Yes." Dan Hong also noticed the change in Huai Jin's attitude.

After obtaining the information that he needed, Huai Jin got up and was about to leave. He walked to the door, thought for a moment and asked, "Is Xuanping Marquis still in the capital?"

Even though Dan Hong addressed the Xuanping Marquis with unfamiliarity, Dan Hong still replied respectfully: "Master left last night."

Huai Jin was not surprised, and gave a light grunt.

Dan Hong turned around and saw him out of the room. Just as she placed her hand on the side of the door, she was stopped by Huai Jin.

"Three days later I will come to retrieve the rouge, and also a copy of the information on the Shen Family Trading Company's Shen Qi. If you continue to be like today with 'no details', then this memory will not be able to continue!"

Dan Hong was shocked. When she regained her senses, Huai Jin had already left the memory's backyard. She had been well-informed in the capital for a long time. Even though she had never come into contact with Huai Jin, she clearly understood the character of this unruly princess and she did not plan to take this threat to heart.

"Qiu Yue!" Dan Hong shouted.

A pink clothed girl answered and Dan Hong handed the rouge in her hand over to her: "Make it in three days."

Qiu Yue reached out to take the prescription, lowered her head to look at it, and revealed an expression of shock: "Who thought of this method?!"

Dan Hong was surprised to see her like this: "What's wrong?"

Qiu Yue pointed at the osmanthus branches and the white vinegar that were on the square and her expression became excited, "All of the rouge today is directly made from crushed petals, turned into paste, and paired with flower dew or fat. Those petals may look gorgeous, but the rouge they produce is always a little thin. However, according to this recipe, the red color of the rouge itself can be forced out with laurel ash and white vinegar to obtain extremely pure rouge! "

Hearing her words, Dan Hong also became curious. Just as he was about to look down, he saw Qiu Yue holding the prescription in her arms and running away excitedly saying, "Qiu Bai! Qiu Bai! I know how to make a real rouge! "

Dan Hong watched as Qiu Yue left. She was a little lost in thought, if Huai Jin took the recipe and went to open a new rouge shop, she would not be able to guarantee that memory would still be able to stand up in the circle of noblewomen in the capital like she was right now.
