There was indeed no one in the alley as Xiao Lan had said. It was very quiet. There was only a sign outside the bookstore with the door closed.

Xiao Lan walked up and casually knocked on the door of a house. After a while, she heard someone coming out from inside. The person opened the door and looked at Yu Yu and Xiao Lan. She then took out two masks and handed them to Xiao Lan.

Xiao Lan gave the mask to Wu Yu, and after the two of them put it on, the man gestured for Wu Yu and Xiao Lan to enter the courtyard. The two of them took seven or eight turns before bringing Wu Yu and Xiao Lan to a room.

Then the man walked out of the room and began to examine the room more closely. There was nothing in the room except a table and a chair in the middle of the room.

There was a blank slip of paper on the table, and beside it was a brush. There was nothing else, so he went up to the table and wrote what he wanted on a piece of paper. Then he folded the brush and put it in a bag hanging outside the door.

After that, the two of them waited in the room. Soon, someone knocked on the door. Xiao Lan opened the door and saw a young servant. She handed the note to Xiao Lan after seeing her open the door.

Xiao Lan took the note and immediately passed it to Yu Yu and looked down at what was written on it. Yu gave Xiao Lan a look and Xiao Lan took out a few silver notes from her pocket and handed them to the servant.

The valet took the banknotes, bowed slightly to Xiao Lan and Jiuyu, and left. When the valet returned, he handed a book to Jiuyu and gestured for her to go ahead.

When Yu Yu and Xiao Lan returned to the Prime Minister's Palace, Yu Yu went back to his room by himself, not allowing anyone to disturb him. Yu Yu went to the dressing table and took out the golden hairpin that Imperial Concubine Liu had given him.

He carefully spun it, revealing the slightly yellowish paper inside. He then sat down at the dressing table, took out the book he had bought from the Bureau, and began to compare them word by word.

It was written that Dongfang Yu was the Grand Princess of the previous dynasty, and also the only princess of the previous dynasty. Thus, the Emperor and Empress's love for Dongfang Yu, who had grown up in such an environment, not only did he not become arrogant and domineering, he instead had good intentions, and was polite to others and fully read poetry.

After growing up, Dongfang Yu was taken in as a disciple by a master of the Dao. However, the previous dynasty was destroyed before he could even finish his studies. And the cause of all this was the Grand Preceptor of the previous dynasty, the current emperor.

In the face of the pain of losing his family, Dongfang Yu did not harbor any hatred. Instead, he changed his name and stayed by his Senior Brother's side. He knew that everything about peace and harmony had changed when Dongfang Yu met a man.

The letter didn't mention the rest, but something bad must have happened due to intuition. What was most important now was Dongfang Yu's name after changing his name, Luzi.

According to what few people knew before, Luzi was her mother. Although it was possible that she had the same name, her intuition told her that this Dongfang Yu was her mother.

When he opened the door, he saw Xiaolan standing guard outside. As soon as she opened the door, she immediately stood up and came up to him.

"Miss?" Xiao Lan looked at Xi Yu and shouted. Hearing that, she retracted her hand and walked back into the room. Xiao Lan quickly followed Xi Yu into the room.

Yu Yu was sitting by the table, knocking the table with his nails. After a while, Yu Yu said to Xiao Lan, "Xiao Lan, ask around about my mother."

Xiao Lan's heart skipped a beat when she heard the word 'fresh'. However, she didn't notice that Xiao Lan had turned away from her and walked out.

Many of the elders in the Prime Minister's mansion had been sent out with few political excuses, and even those who had been lucky enough to stay in the mansion had been beaten to death or sold by Zhao Yuanzhi.

Thus, Xiao Lan wandered around the Prime Minister's Estate but didn't find any useful information, so she could only dejectedly return to the Wutong Garden. "There are very few people in the Young Miss's Estate who know about Lady Xian. Even if there were, they would only meet her once from afar."

Hearing that, Yu Yu Yu immediately frowned and asked curiously: "Why not? Judging from father's age, you can guess that those who serve mother are young, it's impossible for them to go back to retire at such an old age. "

Xiao Lan thought about it for a moment and said, "Maybe it's because someone didn't want the previous wife's name to be spread out, so they found an excuse to send out the previous wife's servants, or sell them elsewhere."

After thinking for a while, he said to Xiao Lan, "You should pay attention to this time. If there is anything about your mother, you must tell me immediately."

After speaking, he suddenly remembered that Cui mama had gone over. He had told Xiao Lan to clean up Cui mama's room, but he was knocked out in the end. When he was brought back, Xiao Lan held the envelope in her hand.

Chu Yu sighed as he thought to himself, If only I could read the contents of that letter. Cui mama is my mother's wedding girl, she must know a lot of things.

Xiao Lan reached out her hand to pinch the center of her brows. She hesitated for a moment, but in the end, she still left without saying anything.

After Xiao Lan left, Xi Yu, who had her eyes closed, immediately opened her eyes. It was unknown what she was thinking as she watched her back.

The next day she woke up and saw the folded paper next to the pillow. She picked it up and opened it and found that the voice in her heart belonged to Grandma Cui.

In the letter, Grandma Cui told her to look for someone called Lin Qing and sighed. Cui mama definitely didn't know that she had met Lin Qing, Wang Xiong, and the others in such a strange situation.

He folded the piece of paper in his hand and placed it in the secret compartment. When Xiao Lan woke up, it was rare for her to wake up. It was like he hadn't seen the letter at all. He was still treating Xiao Lan like before.

However, under such an atmosphere, Xiao Lan couldn't take it anymore, so she fell to her knees in front of the fresh air.

Seeing this, Xiao Lan knew what was going on in Xiao Lan's mind, so she did not speak. Instead, she waited for Xiao Lan to speak.
