Qingya and Li Rui gently put their palms together, an invisible force flowed between them, and a wonderful feeling arose spontaneously. They felt each other's heartbeat, each other's breath, and even the thoughts deep inside each other. A flash of surprise flashed in Li Rui's eyes. He felt the rapid improvement of his own strength. This power made him feel excited and at ease. Qingya also showed a relieved smile. She knew that their fates were closely connected from now on, and they would face all challenges together.

"Ya'er, we have signed the contract, and your strength has been improved. Next, we have to be more cautious." Li Rui held Qingya's hand and looked at her firmly. He knew very well that Li Chengqian would not give up easily.

Qingya nodded lightly. She had already sensed Li Chengqian's anger and unwillingness from Li Rui's mind. He was secretly plotting a revenge plan.

"He will definitely take action, and we must be prepared in advance." Qingya's eyes were sharp, and she was ready to fight.

Li Rui took out an exquisite jade box from Qingya's hand. Inside was a white crystal that emitted a faint glow. He gently placed the crystal in Qingya's hand: "This is prepared for you. It can help you perceive Li Chengqian's thoughts more clearly and help you understand his conspiracy."

Qingya gently stroked the crystal, feeling the warmth and strength it conveyed. She smiled gratefully, her eyes filled with determination.

"Thank you, Li Rui. We will be more cautious and will never let him succeed." Qingya said, looking towards the window with a firm gaze. The palace, shrouded in the night, seemed exceptionally quiet at the moment, but it concealed a turbulent undercurrent.

At this time, deep inside the palace, in Li Chengqian's study, he was burning with rage, his face gloomy, and the memorial in his hand was torn into pieces, scattered on the ground.

"Damn it! How dare they deceive me like this! Do they think they can fight me by forming an alliance? I will never let them go!" Li Chengqian gritted his teeth, with a sinister light flashing in his eyes. He decided to make them pay the price.

"Your Highness, please calm down. What we need to do now is to find an opportunity to counterattack." A guard beside Li Chengqian reminded him. He calmly analyzed the current situation and made plans for Li Chengqian.

Li Chengqian took a deep breath and suppressed his inner anger. He turned his gaze to the guards, his eyes filled with a sinister light. He whispered: "I know what to do. I will make them regret their betrayal!"

"Your plan is full of loopholes." Li Chengqian sneered, staring at Lin Qingya closely, as if he wanted to see through her.

Lin Qingya calmly put down the teacup, gently stroked the rim of the cup, and said lightly: "Your Highness, this is just a draft, it still needs to be improved."

"Perfect?" Li Chengqian was skeptical. He was sensitive to the chord in Lin Qingya's words, but he was not sure what she wanted to do.

"Of course." Lin Qingya stood up, walked to the window, looked at the peonies blooming in the yard, and said slowly: "I know you. You desire power and the recognition of your father, but you are jealous of your father and afraid of the power in his hands."

Lin Qingya turned around and looked at Li Chengqian, with a playful smile on her face, and said softly: "There is no perfect plan here. What's important is who can find the method that suits them best and seize the opportunity to hit the target with one strike."

Li Chengqian remained silent. He was attracted by Lin Qingya's words and could not deny the truth in them, so he decided to believe her.

Lin Qingya deliberately concealed some key links in the plan and left several obvious loopholes to make it easier for Li Chengqian to detect them. She believed that Li Chengqian would be eager to seize these "opportunities", mistakenly thinking that he could win easily.

"We will complete the plan as soon as possible. Your Highness, please remember to come and check it out when the time comes." Lin Qingya's tone was calm, but it revealed an unquestionable confidence.

Li Chengqian nodded. He believed in Lin Qingya's ability and hoped that her plan would allow him to ascend the throne smoothly.

After Li Chengqian left, Lin Qingya returned to her room, closed the window, and the room became dim. She lit a candle, took out the secret letter Li Rui gave her, and read it carefully.

The letter detailed the power distribution, composition, and strengths and weaknesses of Li Rui's men. While reading, Lin Qingya used reading techniques to interpret the meaning behind each word in the letter. She wanted to understand what kind of power Li Rui had and his true purpose.

Lin Qingya frowned slightly. She found that Li Rui's power was stronger than she had imagined. They secretly controlled many important departments in the capital and even infiltrated the imperial palace.

Lin Qingya took a deep breath. She knew that Li Rui was a very dangerous person. He appeared gentle and polite on the surface, but in fact he was very capable. He had been quietly accumulating strength, waiting for the opportunity to launch a counterattack.

Lin Qingya put the letter into the drawer. She wanted to use Li Rui's power to fight against Li Chengqian, but she had to be cautious to avoid being used by him.

Lin Qingya decided to perfect her plan as soon as possible, and then find Li Rui and cooperate with him.

She picked up a pen and began to write and draw on paper, planning her next actions. She wanted to use Li Rui's power to help Li Heng stabilize the political situation. She also wanted to use this opportunity to gain more freedom.

After Li Chengqian left Lin Qingya's room, with a sinister smile on his face, he couldn't help but excitedly began to prepare for a coup, and secretly sent people to monitor Lin Qingya's every move, preparing to completely control Lin Qingya at the critical moment.

He couldn't understand Lin Qingya's thoughts. He only knew that Lin Qingya was a rare chess piece. She could help him gain power, or she could become a tool in his hands.

Li Chengqian's heart is full of wildness and desire. He believes that as long as he can successfully seize the throne, he can get what he wants.

After Li Chengqian left, Lin Qingya asked the maid to prepare a hot bath. She wanted to wash away today's fatigue and think about her next move. She knew that the struggle for power had just begun.

She has to use the power in her hands to find her own freedom in the undercurrent of power struggle.
