With a warehouse full of supplies, I stood alone as king in this chaotic world, gun in hand.

"Swish, swish..." Li Cheng and Li Shuang immediately drew their swords and stood in front of those people.

"Your Highness Prince Rui, please do not disturb the adults from checking the accounts."

"Damn it!" Nangong Xun was truly enraged, his eyes bloodshot as if spitting fire. "I'm taking these officials to the palace to let my father decide. Let's see who dares to stop me!"

He wanted to use Emperor Mingde to frighten them.

However, the Flying Feather Guards remained unfazed and stood there motionless.

"Seize them for me," Nangong Xun ordered his guards.

More than a dozen guards from Prince Rui's mansion drew their swords, and the two sides confronted each other.

"Your Highness, Prince Rui, our lord is here to audit the accounts on the Emperor's orders. Are you here to cause trouble and defy His Majesty's will?" Li Cheng questioned.

"You dog of a servant, you're nothing but Nangong Wu's dog, how dare you question me?"

Nangong Xun was used to being arrogant, and now that he was being questioned by a lowly guard, he felt that his authority had been challenged, so he kicked the guard hard in the chest.

Li Cheng's martial arts skills far surpassed his own; how could he possibly let him hit him? He dodged to the side.

"Damn it!" Nangong Wu's face was as cold as ice. She took out a folding crossbow, opened it, and fired at Nangong Xun.

"Your Highness, be careful..." Qiu Shan exclaimed in surprise and quickly swung his sword to block the short arrow.

Because of his deflection, the short arrow was deflected and grazed past Nangong Xun's ear.

Nangong Xun felt a chill run down his spine, sensing that Nangong Wu really dared to kill him.

"Whoosh whoosh whoosh..." Nangong Wu fired ten short arrows in quick succession.

"Pfft!" Qiu Shan was unable to dodge in time and was hit in the arm by an arrow.

"Nangong Wu, how dare you shoot me?" Nangong Xun was furious.

He had grown up in luxury and privilege, and to be beaten by this woman time and time again had truly enraged him to the extreme.

"Because you deserve to die!" Nangong Wu untied the long whip from her waist and lashed it at Nangong Xun.

"Nangong Xun, I'll kill you today!"

"Your Highness, hurry and go!" The guards of Prince Rui's mansion rushed to protect Nangong Xun.

"Crack crack crack..." The crisp sound of whips lashing out rang out.

Several guards had their backs slapped until they were covered in blood.

"Your Highness, let's go!" Qiu Shan ignored the injury on his arm and dragged Nangong Xun outside.

Seeing that Nangong Wu was so difficult to deal with and wouldn't listen to either soft or hard tactics, Nangong Xun was furious.

Seeing that his men were no match for the Flying Feather Guards, he had no choice but to leave the Ministry of Revenue.

"Nangong Wu, I'm not done with you yet!" He was furious, he really didn't know why his father would give such a vicious and stinking woman such an important position.

"Your Highness, let's go back and think of a solution!" a guard advised him.

"Go back to what?" Nangong Xun said irritably, kicking him. "Useless, you're all useless."

"Your Highness, perhaps we should..." Qiu Shan whispered a few words in his ear.

Nangong Xun's eyes flashed with ruthlessness. "Fine, I'll do as you say." He turned and left after saying that.

Inside the government office.

When Jiang Shuofeng and Jiang Xin saw Nangong Xun leave like that, despair was evident in their eyes.

Nangong Wu dared to arrest them, so it's highly likely she's already found some dirt on them.

If even Prince Rui can't protect them, then they're doomed.

"Li Cheng, take these people to the Ministry of Justice and hand them over to the Minister of Justice personally. Tell him that these people are serious criminals, and if they accidentally escape, I will hold them accountable!" Nangong Wu instructed Li Cheng.

"Yes," Li Cheng replied, turning around and waving his hand. "Take them all away!"

The guards dragged the dozen or so people out and sent them to the Ministry of Justice.

The lobby finally quieted down.

Seeing that Nangong Wu dared to stand up to Prince Rui, Xu Gui was even more convinced that she could get to the bottom of things and clear up all the unclear accounts from the past.

The sound of an abacus clicking away echoed in the lobby.

Nangong Wu walked around the lobby and discovered that these fortune tellers were still using single-entry bookkeeping.

Single-entry bookkeeping lacks cross-referencing and a debit-credit balance mechanism, making it extremely difficult to verify the accuracy of accounts through trial balance and to detect errors or omissions.

Looking at all those boxes of ledgers, she realized it would probably take more than half a month to check them all.

She felt that this method of calculation was not working, so she sat down, picked up the ledger, and checked the accounts using the double-entry bookkeeping method from her previous life.

One of the officials from the Hanlin Academy went to the outhouse and when he returned, he saw that Nangong Wu had also checked quite a few account books, and seemed to be doing it even faster than them, which made him curious.

"Your Highness, I didn't expect you to be so proficient in these administrative matters."

"Don't forget, my father's Huo family trading company is spread across six kingdoms. I am his only daughter; I have no choice but to learn from him!"

Nangong Wu used her father's business name as a shield, saying, "I've been doing accounting for so many years, and I've created my own calculation method that's not easy to make mistakes."

"A calculation method?" A glint flashed in the eyes of the person in charge.

Upon hearing her words, everyone stopped what they were doing with their abacuses.

They've dealt with accounts for half their lives and haven't heard of a better way of keeping accounts than theirs.

"My accounting method is called 'double-entry bookkeeping.' This method follows the principle that every debit must have a corresponding credit, and that debits and credits must equal each other. This allows every income and expenditure to be verified against each other, leaving no opportunity for those who want to embezzle..." Nangong Wu didn't mind telling them about this accounting method.

"Double-entry bookkeeping?"

Hearing her words, everyone's eyes lit up and they gathered around.

"This double-entry bookkeeping method is ingenious; it will save us a lot of manpower in the future."

Nangong Wu added, "Furthermore, I have an algorithm called the 'Verification Algorithm,' which can quickly screen out questionable accounts and is very suitable for verifying the current ledgers!"

The official in charge of the Hanlin Academy was extremely excited upon hearing this. "Your Highness, could you please teach us this method?"

"It's actually very simple..." Nangong Wu explained the accounting concepts from her previous life to them in a concise manner.

Suddenly, a loud "bang!" was heard.

Nangong Wu looked up and exchanged glances with several Flying Feather Guards. The sound seemed like a bomb to them.

A guard rushed in, "Your Highness, something has happened at the palace!"

"What?" Nangong Wu suddenly stood up. "What happened?"

The Flying Feather Guard looked grim. "This subordinate is unaware of the situation. It was the Prince's residence that fired an emergency signal flare; something must have happened."

"Your Highness, I'll go back and check first." Li Cheng and Li Shuang immediately ran outside.

They brought quite a few people with them today; they need to go back and provide support as soon as possible.

"Prepare the horses." Nangong Wu followed them out.

Since Nangong Xun didn't gain any advantage just now, he's very likely to send people to storm the palace again.

With Xiao Lin and dozens of Flying Feather Guards in the Prince's Mansion, it wouldn't be so easy for those people to succeed.

"Your lightness skills are good, go back and provide support first," Nangong Wu instructed the few Flying Feather Guards who remained.

"This..." Fei Yuwei hesitated.

"This is an order. Go back and protect the three children." Nangong Wu's voice was stern.

"Yes!" The Flying Feather Guard had no choice but to use his lightness skill to leave first.
