The old butler slapped his thigh, his cane thumping against the brick floor. "Miss, you're wise! The general's cenotaph is on the side of Langya Mountain!"

Chun Tao rubbed her hands together in excitement: "Miss, let's go treasure hunting! If we dig up a hundred thousand taels of silver, we can beat Liu's face!"

"What's the hurry?" Shen Weiwan rolled up the map and stuffed it into her sleeve pocket, then hid the wooden box back into her cotton-padded jacket. "First, hide this treasure in my secret compartment. Don't let that old, pious woman Liu find it." She looked at the box full of military books and suddenly remembered something. "Old housekeeper, didn't my father have an affair with the Seventh Prince..."

Before she could finish her words, there was a sudden creaking sound as the door opened outside the warehouse. Chuntao screamed and blew out her lantern. The three of them ducked and hid in the gap between the wooden boxes behind them. In the moonlight, Liu and Lu'e walked in, lanterns in hand. Lu'e was holding a crowbar, her teeth chattering with fear. "Madam, I thought I heard someone..."

"Shut up!" Liu glared at her fiercely, the lantern light shining on her sallow face, "That little bitch Chen Weiwan has been running to the warehouse every day recently. She must have hidden the general's treasure! Find it carefully for me!"

Shen Weiwan clenched her fists in the dark, digging her nails into her palms. Liu hadn't given up! She dragged the old housekeeper and Chuntao towards the back door. As soon as she reached the door, she heard Liu scream, "Found it! The box is empty!"

Chun Tao almost cried out, but Shen Weiwan covered her mouth. The old housekeeper whispered in her ear: "Don't panic, Miss. That's the box where you put your holiday account books."

Shen Weiwan stole a glance and saw Liu jumping up and down at the empty box, the crowbar hitting the box board with a dull thud. She couldn't help laughing, and dragged the two of them out of the warehouse, the night wind blowing her skirt and saying, "Chun Tao, go to the accounting office!"

"Where are you going, Miss?" Chuntao asked breathlessly.

"My father put a note in the military book," Shen Weiwan ran as fast as she could, her hairpins jingling, "and it said, 'Meet the Seventh Prince and you will solve the mystery of the military pay!'"

In the Seventh Prince's study, Xiao Yu burst into laughter as he gazed at the secret report in his hand. The map of Langya Mountain on the desk was illuminated by the candlelight. His personal guard whispered, "Your Highness, what about Miss Shen..."

"She found the general's wooden box." Xiao Yu put down the secret report and tapped the cenotaph mark on the map with his fingertips. "The general really did leave it to her."

The guard was surprised: "But didn't the general give the military pay..."

"Of course the military pay was confiscated," Xiao Yu said with a smile, picking up the copy of The Art of War by Sun Tzu on the desk—the annotated copy by Shen Weiwan's father. "But the general never left his daughter anything but gold and silver." He raised his eyes and ordered, "Tell the secret guards to prepare carriages and horses at Langya Mountain. Don't let the Second Prince's men ruin Miss Shen's treasure hunt."

At the same time, Shen Weiwan dug out her father's old account book in the accounting office and found a slip of paper in the interlayer. On it were eight cinnabar characters that could be seen through the paper: "Seventh Prince knows, you can ask Xiao Yu."

"It really has something to do with that guy!" Shen Weiwan slapped the note on the table, remembering the playful smile of the Seventh Prince when he gave Croton to her, "Chun Tao, prepare the horses! Go to the Seventh Prince's Mansion!"

Chun Tao was dumbfounded: "Miss, it's already the middle of the night!"

"What happened at midnight?" Shen Weiwan raised an eyebrow, remembering the "speed is the essence of war" in her father's military book. "Just say I'm looking for him... to borrow soldiers! No, to borrow money!"

The old butler stroked his beard and smiled: "My dear lady, if the general knew about this, he would be very proud of your courage."

Chen Weiwan gazed out the window at the crescent moon, her palms suddenly burning as she recalled the maxim "know thy enemy, know thyself" from her father's military manual. Perhaps her father was right, true wealth lies in the ability to defend one's home and country, but how could she fight the Liu family without money? She grabbed a map and rushed out of the accounting office: "Let's go! Even if we have to drag the Seventh Prince from his bed, we'll find out the whereabouts of the military pay!"

Chun Tao watched her young lady's hurried back and reluctantly followed. The old housekeeper watched them disappear through the moon-shaped gate and murmured, "General, your daughter is indeed like you, a remarkable woman who is no less capable than any man."

In the darkness of the night, Shen Weiwan galloped towards the Seventh Prince's residence, the sheepskin map rustling in her sleeve. Little did she know, this map held not only her father's "private money," but also the key to unlocking years of injustice in the General's residence. Meanwhile, in the Seventh Prince's residence, Xiao Yu was ordering the preparation of hangover soup. He gazed out the window and smiled, "Shen Weiwan, Shen Weiwan, I want to see how you will use this box of military tactics to overturn the turmoil in the capital."

A treasure hunt for "private money" is about to begin, and yet, in the storehouse, Madam Liu is still cursing at an empty chest, completely unaware that the wealth she covets has already fallen into the hands of the legitimate daughter she considers "foolish." Shen Weiwan gazes at the lights of the Seventh Prince's residence ahead, a confident smile playing on her lips. "Dear father, I accept your "private money." As for these military books, I will study them carefully after I've dealt with Madam Liu, so that those men who look down on women will see that the legitimate daughter of a general's mansion is capable of managing a household and safeguarding the country."
