"Remember, this matter must not be made public. Only the two of us know about it." Lin Qingya's voice was low, as if she was talking about something extremely secret.

Li Chengqian nodded cautiously. He understood what Lin Qingya meant. Once this matter was exposed, it would bring great risks. Not only would it lead to Defei's revenge, but it would also make other princes aware of his ambitions and pose a great threat to him.

"Don't worry, I will never let this matter leak out." Li Chengqian said in a low voice, with a firm light in his eyes. He believed in Lin Qingya, and he believed that he could succeed, completely defeat Concubine De, and win the final victory.

"Very good." Lin Qingya nodded with satisfaction, a sneer appeared on the corner of her mouth, and her eyes were full of cold light. She had already begun to plan her next move. She would use Li Chengqian's ambition to control him step by step and make him a sharp weapon in her hands.

"Brother Chengqian, I have already made arrangements. If you follow my plan, I guarantee that you will be able to rescue that person successfully." Lin Qingya said. She took out a piece of paper from her sleeve, which was covered with dense handwriting. She handed the paper to Li Chengqian and said, "This is my plan. Take a close look at it."

Li Chengqian took the paper and read it carefully. His brows gradually wrinkled and a trace of worry flashed in his eyes, but he quickly regained his composure. He was full of confidence in Lin Qingya's plan. He believed that as long as he acted according to the plan, he would be able to successfully rescue the man without exposing his identity.

Li Chengqian put the paper away, his eyes filled with determination. He nodded to Lin Qingya and said, "I understand. I will act according to the plan."

"Very good." Lin Qingya looked at Li Chengqian with a slight smile on her face. She had already begun to look forward to Li Chengqian's actions. She believed that Li Chengqian would definitely act according to her plan, successfully rescue that person, and clear the obstacles for her.

"That man is now imprisoned in the cold palace of the imperial palace by Concubine De. You must be careful and don't let Concubine De discover your whereabouts." Lin Qingya explained to Li Chengqian, her eyes flashing, as if she was thinking about the next plan.

"I know, I will be careful." Li Chengqian nodded, he took a deep breath, his eyes full of determination. He decided to take advantage of this opportunity to completely get rid of Defei's control and become the real one in power.

"Very good, Brother Chengqian, I believe you can succeed." Lin Qingya looked at Li Chengqian with expectations in her eyes. She believed that Li Chengqian could do it, and she would use Li Chengqian to completely defeat Concubine De and achieve her goal.

Li Chengqian nodded to Lin Qingya, then turned around and quietly left the garden. He couldn't wait to take action to remove the thorn in his side, Concubine De, and clear the obstacles for his own path to power. His ambition had begun to swell, and he believed that he would eventually become the master of the Zhou Dynasty.

Lin Qingya watched Li Chengqian leave, her lips slightly raised, she sighed softly, and murmured to herself: "Brother Chengqian, you will never understand that you are just a chess piece in my hand." A sly smile appeared on Lin Qingya's face. She had begun to plan how to use Li Chengqian to completely defeat Concubine De and eventually gain more power. She believed that her plan would succeed because she had the ability to read minds, she could see through everyone's mind, and she could use all available people and resources to win in the end.

At night, Li Chengqian sneaked out of the palace from the side door with several guards. According to Lin Qingya's plan, he came to a dilapidated house on the outskirts of the city. In his hand, he held tightly the secret letter from Lin Qingya, which contained a detailed rescue plan.

"Your Highness Cheng Qian, are we really going to do this?" a guard asked in a low voice. He looked at the dilapidated house in front of him and felt a little uneasy.

"Of course, this is Miss Lin's plan, and we must act according to the plan." Li Chengqian said firmly, with a cold light flashing in his eyes. He took a deep breath, straightened his clothes, and prepared to enter the house.

"Be careful." The guard reminded, holding the sword tightly in his hand and scanning the surrounding environment vigilantly.

Li Chengqian nodded, and he entered the house carefully with the guards. They followed the route in the secret letter, avoided the guards, and finally found the important person imprisoned in the cold palace—Duke Zhenguo, a founding hero of the Zhou Dynasty, who was now under house arrest by Concubine De.

When the Duke of Zhenguo saw Li Chengqian, a trace of excitement appeared on his face. He said excitedly: "Your Highness, you are finally here."

"Duke Zhenguo, I will definitely rescue you." Li Chengqian said in a firm tone. He stretched out his hand and helped Duke Zhenguo up.

"Thank you, Your Highness. I will definitely repay your kindness." Duke Zhenguo said in a low voice, his eyes filled with gratitude.

"Time is running out, we must leave as soon as possible." Li Chengqian glanced at the surrounding environment and said to Duke Zhenguo in a serious tone.

"Okay, let's go." Duke Zhenguo nodded, and he followed Li Chengqian closely towards the exit of the mansion.

As soon as Li Chengqian and the Duke of Zhenguo walked out of the house, they saw several men in black blocking their way. The men in black were holding swords in their hands and staring at them fiercely.

"Who are you?" Li Chengqian frowned and asked vigilantly.

"We are Concubine De's people, don't even think about leaving!" A man in black said coldly, swinging the sword in his hand and rushing towards Li Chengqian and Duke Zhenguo.

"Stop them!" Li Chengqian ordered the guards. He drew his sword and rushed towards the men in black.

The battle broke out instantly. The guards fought hard, while Li Chengqian protected the Duke of Zhenguo. They fought hard to carve out a bloody path and ran towards the palace.

Concubine De stood in the palace, looking at the battle in the distance with cold eyes, a sneer on her lips. She had known that Li Chengqian would come to rescue Duke Zhenguo, and she had already made preparations.

"Li Chengqian, you will never escape from my grasp!" Defei said in a low voice, her eyes filled with viciousness.
