"Master Li Rui is imprisoned in the secret room of Concubine De's bedroom." After saying this, Uncle Wang lowered his head and dared not look at Lin Qingya again.

Lin Qingya's face was solemn. The Defei's bedroom was heavily guarded, and it would be extremely difficult to sneak in and rescue Li Rui.

"I know." Lin Qingya said calmly, but she had already started thinking about countermeasures. She needed a helper, someone who could help her sneak into the palace of Concubine De.

At this time, Lin Qingya remembered the previous "deal" with the crown prince Li Chengqian. Li Chengqian promised to help Lin Qingya, but the condition was that Lin Qingya helped him to seize the throne.

"Too late..." Lin Qingya murmured to herself. She decided to go and check out Li Chengqian's personality first.

Lin Qingya walked to the palace, and the guards at the gate bowed and saluted immediately when they saw her: "Sister Lin, you are here."

Lin Qingya nodded, signaled to the guards, and then walked straight to Li Chengqian's study.

"Brother Chengqian, how have you been recently?" Lin Qingya asked. Her tone was relaxed, but her eyes were carefully observing Li Chengqian's expression.

Li Chengqian was sitting at the desk, reviewing memorials. When he heard Lin Qingya's voice, he raised his head and smiled faintly: "Sister Qingya, you are here, please sit down."

Lin Qingya sat down and looked around the study. She noticed that there were many memorials about Concubine De on Li Chengqian's desk. She knew that Li Chengqian was full of love for Concubine De.

"Brother Chengqian, I heard that Concubine De is living a very comfortable life recently?" Lin Qingya asked deliberately, with a hint of teasing in her tone.

Li Chengqian's face flashed with anger. He put down the memorial and said, "Sister Qingya, why do you say that? Concubine De is my father's favorite concubine. She is living a good life. This is as she should be."

"Really?" Lin Qingya said with a smile. She used her reading skills to explore Li Chengqian's interior.

Many negative comments about Concubine De flashed through Li Chengqian's mind. He thought that Concubine De was a scourge in the palace. She interfered in state affairs and even colluded with foreign officials in an attempt to undermine the imperial power.

"Brother Chengqian, you don't have to pretend anymore." Lin Qingya put down her teacup, her tone became serious, and said, "I know you are full of love for Concubine De."

Li Chengqian's face turned pale, and he asked in panic, "Sister Qingya, what did you say? I...how could I be dissatisfied?"

Lin Qingya smiled and said, "Brother Chengqian, there is no need for us to lie to each other. If you want to seize the throne, Concubine De is one of the biggest obstacles. I know you have been looking for opportunities to strike her down."

Li Chengqian remained silent. Lin Qingya saw through his thoughts, but he did not deny it.

Lin Qingya's lips curled up into a perceptible smile. She knew that she had successfully touched the deepest secret of Li Chengqian. She did not continue to ask, but changed her tone and said, "Brother Chengqian, I can help you get rid of Concubine De, but you need to do me a favor."

Li Chengqian was slightly stunned, then he looked up at Lin Qingya, a hint of suspicion flashed across his eyes, and asked, "What help?"

Lin Qingya smiled gently and said, "I want you to help me save someone, a very important person."

Li Chengqian frowned, as if thinking about Lin Qingya's words, and asked in a low voice: "Who?"

Lin Qingya cast her gaze towards Li Chengqian, a sly look flashing across her eyes, and she said, "Li Rui."

Li Chengqian's pupils suddenly shrank, and he asked in surprise: "Li Rui? How did you know that you were imprisoned by Concubine De?"

Lin Qingya did not answer Li Chengqian's question. She just said calmly: "I can help you get rid of Concubine De, but you need to help me rescue Li Rui. This is the condition of our cooperation."

Li Chengqian's eyes flashed with hesitation, as if he was weighing the pros and cons. Lin Qingya quietly waited for Li Chengqian's answer, she knew that she had taken the initiative.

"Okay, I promise you." Li Chengqian finally nodded and agreed to Lin Qingya's request. There was a hint of viciousness in his eyes, and he seemed to have decided to use this opportunity to get rid of Concubine De.

Lin Qingya's lips curled up into a perceptible smile. She knew that she had successfully used Li Chengqian's wildness, and she believed that she would rescue Li Rui soon. She stood up and said, "Brother Chengqian, you should know where Concubine De's bedroom is."

Li Chengqian nodded and said, "I know, but she has guards around her."

Lin Qingya smiled and said, "I have my own way. You just need to help me open the back door."

Li Chengqian's face turned serious and he asked, "What are you going to do?"

Lin Qingya did not answer Li Chengqian's question. She just smiled and said, "Just do your job well and leave the rest to me."

Lin Qingya turned and left, her body full of confidence. She had found the key to the Defei's palace, and also found a collaborator who could help her complete her plan. She believed that she would soon rescue Li Rui and reveal the true face of the Defei.
