With Bechuk's wedding date approaching, Lanqin began to plan what dowry to prepare for him. Although the Fourth Prince had bestowed a considerable amount upon her, Lanqin still felt that the more dowry she had, the more value she would receive in her husband's family. Moreover, over the years, Lanqin had been mindful of potential future needs and had accumulated a considerable amount of wealth, just in case something unexpected happened in the future.

Seeing Lanqin deep in thought, propping her chin on her hand and recording calculations with an abacus, Baoqin deliberately walked up behind her in a low voice and asked, "Your Highness, what are you thinking about?"

Lanqin was startled and clutched the account book to her chest, saying nervously, "You scared me to death..."

Baoqin put down her teacup and said apologetically with a smile, "This servant knows her mistake. What is Your Highness doing? Do you need this servant's help?"

Lanqin waved her hand and hurriedly said, "I'll do the accounting myself, you wouldn't understand anyway..." Actually, the ledger in Lanqin's hand contained the income from her shop and hot pot restaurant outside the palace. She hadn't usually taken care of it much, but today, having nothing else to do, she calculated it and was surprised to find that the income was quite considerable.

Baoqin poured Lanqin a cup of tea and waited by her side. Lanqin put down the account book and sighed, "Biechuke is getting married soon, and I, as her mother, have to prepare her dowry."

Baoqin said, "That's not easy. Your Highness can simply summon the princess to choose together..."

Lanqin suddenly understood and immediately sent Baoqin to invite Biechuke to Changchun Palace. Lanqin had a private vault, like a modern safe, filled with all her treasures and precious items bestowed upon her by the Fourth Prince. Apart from giving some to other concubines, Lanqin kept the rest hidden in a side room behind her main hall. The key was on Lanqin's person, and only she could open this private vault; no one else even knew what it looked like inside.

As soon as Bechuk arrived, Lanqin pulled her towards the back of the main hall. They stopped in front of a thick wall, and Bechuk was taken aback: "Mother, what are you doing?" Lanqin smiled mysteriously, reached for a porcelain bottle on a low cabinet, and gently twisted it. The wall instantly slid open with a loud bang.

To Bechuk's astonishment, Lanqin pulled a small key from her pouch and led Bechuk inside. Behind the wall was a small door; Lanqin opened it with the key, revealing the treasures inside.

Bechuk entered slowly, dumbfounded. The walls were lined with antique shelves, upon which sat numerous large and small boxes carved from dark black nanmu wood with peony designs. Bechuk randomly opened one box, revealing a white jade revolving lotus-seed vase. He carefully stroked the vase, exclaiming in amazement, "My goodness, Mother, you have so many treasures…"

Lanqin smiled dismissively, and Labecchuk opened the boxes one by one. There were white jade floral incense holders, green jade longevity scepters, white jade phoenix water bowls, white jade auspicious scepter covered incense burners, agate gold-plated bowls, gold-inlaid gemstone gourd bottles, and crane-crowned red ornaments. The most valuable item was a silver gilt Amitabha Buddha statue, which made Labecchuk's jaw drop.

Lanqin was about to introduce more when Bechuk waved his hand, saying, "Mother, you could practically open an antique shop..."

Lanqin smiled and said, "Your mother still has many jewels and ornaments that you haven't seen yet. Besides, your mother already has enough shops; there's no need to sell these treasures..."

Lanqin walked to a display shelf, gently opened a box, and inside was a dazzling winged golden crown. Lanqin smiled shyly, pointed to the crown, and said, "Besides, many of these were gifts from your father, the Emperor. I've treasured them all and can't bear to show them to others..."
