Lin Qingya smiled slightly and said softly: "Brother Chengqian, you know a lot about the Tianji Mirror. It is a royal secret treasure. Where did you hear this news from?" As she spoke, she observed Li Chengqian's reaction. After hearing the three words 'Tianji Mirror', he looked obviously nervous, and his eyes wandered around, as if he was hiding something.

"I, I heard some rumors," Li Chengqian explained in a panic, with a blush on his cheeks. "This Tianji Mirror is a magical object. I heard that it can predict the future. I'm very curious, so I want to know more about it." As he spoke, he observed Lin Qingya's expression calmly, trying to judge from her reaction whether she had discovered his true intentions.

"Brother Chengqian is really curious," Lin Qingya said with a smile. She pretended to be indifferent and deliberately exposed her flaws to let Li Chengqian relax his vigilance. "However, this Tianji Mirror is not something that can be studied casually. I heard that the power of this mirror is very strong. Once used improperly, it will bring disaster."

"Yes, yes," Li Chengqian nodded repeatedly, secretly delighted. Lin Qingya really knew nothing about the Heavenly Secret Mirror. This was a great opportunity for him. He pretended to be casual and said, "However, I am really curious about what secrets this Heavenly Secret Mirror has. Yaer, since you know a lot about it, can you tell me some stories about it?"

"Brother Chengqian, you are so forgetful," Lin Qingya pretended to be angry and said, "I remember you talked to me last time. I said I didn't know much about the Tianji Mirror. I just heard some legends. You haven't forgotten it again?" As she spoke, she glanced at the guards standing not far away with the corner of her eye. They had begun to secretly monitor Li Chengqian according to her arrangement.

Li Chengqian felt a little embarrassed when he heard Lin Qingya's words, but he quickly calmed down and said with a smile: "Yaer, I may have remembered it wrongly. However, since you know something about the Tianji Mirror, can you reveal some of its secrets? I'm really curious." As he spoke, he moved closer to Lin Qingya, his eyes full of desire. He was eager to know whether Lin Qingya knew the real secret of the Tianji Mirror, so that he could make a better plan to seize this treasure.

Lin Qingya shook her head lightly, her tone full of helplessness, "Brother Chengqian, I really don't know much about this Heavenly Mirror. You should go ask father. He should know more about it than me." As she spoke, she pretended to push Li Chengqian aside, signaling with her eyes to the guards to be prepared and ready to take action at any time.

Li Chengqian frowned slightly, feeling a little uneasy. He originally thought that he could use Lin Qingya's knowledge of the Tianji Mirror to obtain some useful information, but Lin Qingya's answer disappointed him. He knew that Lin Qingya must have concealed some information, so he decided to continue testing her and get the information he wanted from her.

"Brother Chengqian, how much do you know about the Tianji Mirror?" Lin Qingya asked with a hint of cunning in her eyes. She wanted to test Li Chengqian to see if he knew the true secret of the Tianji Mirror and whether he really wanted to get this treasure.

Li Chengqian was slightly stunned when he heard Lin Qingya's question. He originally thought that Lin Qingya would continue to perfunctorily answer him, but he didn't expect that she would take the initiative to ask about the Tianji Mirror. He knew that Lin Qingya had been hiding something, and she must know the secret of the Tianji Mirror, but he wanted to get the truth from her, but it was as difficult as picking up a needle in the sea.

"Ya'er, why are you asking this?" Li Chengqian pretended to be calm, but there was a hint of panic in his tone. He tried to hide his uneasiness, but his unnatural tone and panic expression still betrayed his inner thoughts.

"Nothing. I just think that this Tianji Mirror seems to be related to the fate of our family, and I want to learn about it." Lin Qingya said, with an indescribable complex emotion in her eyes. As she spoke, she gently stroked the jade pendant in her hand. This jade pendant was found in the family's secret room. There were some strange patterns carved on it. She thought that these patterns might be related to the secret of the Tianji Mirror.

"Ya'er, don't you believe in your father?" Li Chengqian's tone was filled with dissatisfaction. He couldn't understand why Lin Qingya was so obsessed with the Heavenly Mirror. He didn't want her to get involved in this matter because it involved the secrets of the royal family. Once Lin Qingya knew about it, it would bring huge risks.

"Father is certainly trustworthy, but I always feel that this matter is not so simple." Lin Qingya shook her head gently, her tone full of determination. She has begun to suspect that the secrets of the family and the secrets of the Tianji Mirror may be more complicated than she thought, and she must find the truth.

"Ya'er, if you have any questions, you can ask father anytime. Don't let your imagination run wild." Li Chengqian said, his tone becoming softer. He wanted to comfort Lin Qingya and tell her not to continue investigating the matter, but Lin Qingya's firm eyes made him even more uneasy.

"Brother Chengqian, are you really completely unaware of the Heavenly Mirror?" Lin Qingya asked with a hint of sarcasm in her tone. She wanted to completely expose Li Chengqian's disguise and see what secrets he was hiding.

Li Chengqian's face turned pale in an instant. He clenched his fists tightly and remained silent.

The guards around held their breath and watched the situation develop. They knew that a storm was about to come.

Lin Qingya sneered. She knew that Li Chengqian had exposed himself and she had found a way out. She coughed softly and said in a clear voice, "Brother Chengqian, you should know that no matter what secrets you hide, they can't escape my eyes."

When Li Chengqian heard Lin Qingya's words, he suddenly felt despair. He originally thought that he could keep it a secret, but he didn't expect that his secret would be easily discovered by Lin Qingya.

"Ya'er, what exactly do you want?" Li Chengqian asked in despair. He finally realized that he had fallen into Lin Qingya's trap.

Lin Qingya smiled gently, her eyes filled with wisdom. She knew that now was the time to reveal the truth.

"Brother Chengqian, let's find a quiet place and talk slowly." Lin Qingya said, turning and walking deep into the palace. She wanted to take advantage of Li Chengqian's fear and force him to tell her all his secrets.

Li Chengqian hesitated for a moment, but finally followed Lin Qingya's footsteps. He knew that he had no choice.

Lin Qingya and Li Chengqian disappeared into the depths of the palace, and the secret between them was buried in the long river of history.
