After hearing the system's explanation, Yao Guangyue suddenly realized that it seemed like she hadn't seen Xiao Cui for a while.

And there has been something strange going on in the mansion recently. It seems like most of the people are gone, and they are all looking for things inside and outside.

It was at this time that the imperial concubine proposed to leave the city wall and go to the disaster area in Wancheng.

Kang Nan's attitude towards this was very strange, and he seemed a little reluctant to let the concubine and the others leave.

"Your Highness, you and the little princess have just arrived here and haven't seen the local customs and practices of the city yet. Are you leaving now?"

The imperial concubine sat upright, holding Yaoguangyue in her arms. She spoke not only quickly, but also with a sense of being a watcher of a play.

"This time, I brought the little princess out of the palace to visit the disaster victims in Wancheng. This is also what Your Majesty wished. I just thought that the eldest prince was here, so I came along."

"Now that I see the people of Wangcheng living and working in peace and contentment, it's not like my trip was in vain. However, my destination this time is Wancheng, so I can't stay any longer. I can only thank General Kangnan for his hospitality."

Kang Nanxiao had already said this much, and it was difficult for him to stop him.

But after leaving the city wall, it is really necessary to find out whether the imperial concubine is going to Wancheng or returning to the imperial city.

But Yao Guangyue didn't understand. Since she had already found the account book, why should she leave Wengcheng at this time? Shouldn't she take this opportunity to capture him?

"System, what's going on? We've already found the account book, why are you leaving? Shouldn't you stay here and root out this traitor?"

[Remind the host, you are still a child. The army must be sent to apprehend traitors. If you are kidnapped here, wouldn't that hinder us?]

Yao Guangyue was indeed a little excited. It was the first time she had seen the swordplay of ancient strategists and politicians, so she was a little excited and neglected herself.

"You're right. Letting us leave now is most likely to ensure our safety. Does that mean we've reached the final stage?"

[This system cannot detect this, and the host can only find the truth himself. ]

Although he did not learn about the development of the situation from the system, his mother's subsequent actions confirmed this.

After their carriage left the city wall, the imperial concubine secretly got off the carriage with Yao Guangyue and hid in a small place not far from the city wall.

The imperial concubine's carriage left with the farewell of a group of people, and among the crowd, Qin Xuezhen's eyes were fixed on the carriage with extremely hateful eyes.

Tang Xicheng, who was standing beside her, was wearing a bamboo hat. He lowered his head, patted her shoulder, and took her away.

After the two men arrived at the inn where they were hiding, Tang Xicheng couldn't help but ask.

"You seem to hate that imperial concubine? Did you offend her before?"

Qin Xuezhen sighed and recounted the story of the inexplicable feud between him and the imperial concubine. It sounded like a trivial matter, and Tangxicheng felt a little bored listening to it.

"It's just a small matter. The women in the harem are jealous of each other. Miss Qin is beautiful, and the harem is most afraid of young and beautiful women, so it's normal for the imperial concubine to target you."

Hearing him say this, Qin Xuezhen felt as sweet as if she had been fed with honey, and she handed over the things she had stolen to him.

"Your Highness is right. Let's not talk about her anymore. This time, I was able to sneak into the Kang Mansion and really gained a lot. Although they chased me and forced me to hide outside for several days, I was lucky enough to complete my mission."

As Qin Xuezhen spoke, she put the account book in Tang Xicheng's hand. Seeing the account book, Tang Xicheng's eyes suddenly lit up.

"Great! With this account book, Kang Nan won't dare to act rashly again. If he dares to do anything reckless in the future, we will hand this account book directly to the Yaoguang Kingdom's royal family. The Emperor of Yaoguang Kingdom will definitely not tolerate him!"

Tang Xicheng had a good idea in his mind, but the smile on his face did not last long.

After casually opening the account book, what is recorded in it?

"Hmm? Two bowls of plain noodles for four cents, a night's accommodation for five cents, and a doctor for two hundred yuan... What is this? Qin Xuezhen, what did you bring back?"

Tang Xicheng threw the account book out directly. Qin Xuezhen was also confused when she heard what he had just read out.

"That's impossible. I stole this after sneaking into the secret room with great difficulty. Besides, hasn't Kangnan been sending people to catch me?"

In just that moment, Tang Xicheng's suspicious gaze fell on Qin Xuezhen's face. When Qin Xuezhen saw his suspicious look, her heart sank.

"Your Highness, you don't think I've swapped the account books, do you?"

Tang Xicheng didn't say much. He was just subconsciously suspicious just now.

If I think about it calmly, it shouldn't be possible. She is a young lady from a noble family who followed me regardless of everything. Why would she stab me in the back?

"Miss Qin, please don't misunderstand me. I'm not doubting you, but I'm wondering if you've fallen into someone's trap!"

Having said that, Qin Xue was sure that she was not mistaken based on that suspicious look just now.

"Your Highness, there's no need to explain. I know Your Highness won't doubt me. But I don't know why this account book has changed. It looks like a trivial account book. Why is Kang Nan so obsessed with it?"

Tangxicheng was still relatively rational. After thinking about it, he felt that this thing must have been swapped.

"It seems that this account book has indeed been swapped!"

"That's impossible. After I got the account book, I have been hiding outside the city and have not had contact with anyone. I have never left this account book with me. It is impossible for someone to have swapped it."

Qin Xue was anxious to explain, she was really afraid that this person would doubt her.

"Miss Qin, please don't misunderstand me. What I mean is that this account book was most likely replaced when it was in Kang Mansion, but Kang Nan didn't know about it."

Qin Xuezhen frowned, thinking that the imperial concubine and the little princess appeared in Kang Nan's house for no reason. There must be a reason.

"If there's anyone who can be replaced, it's probably this imperial concubine. Otherwise, why would she, a dignified imperial concubine with a little princess, live in a minister's house for so long?"

Tangxi City keenly realized that Kangnan might not be able to be saved.

"If it is really the Imperial Concubine and the others who took the account books, we must quickly find the army Kangnan is hiding. If we can take them away during the chaos and bring them completely under my control, they will become a force that cannot be ignored."

Just as Tang Xicheng finished speaking, a voice suddenly came from the system in Qin Xuezhen's body.

[Host reminder: Since both of the Medical Book Goddess's missions have failed, this system has decided to punish you.]

[Ah? System, you're crazy!]
