The autumn wind was howling, the leaves were falling, and the atmosphere inside and outside the palace walls was even more eerie than this autumn. Lin Qingya sat in the study, holding a letter in her hand, with a faint smile on her lips. The letter was sent by Li Rui. The content was simple and concise, but it accurately described Li Chengze's current state: wild and full of doubts. She gently put down the letter, and her slender fingers tapped on the table, making a slight sound. Various ancient books and scrolls were placed in the study, and the air was filled with a faint scent of ink.

Lin Qingya picked up the pen, wrote a few lines on the letter paper, and then sealed it with a thin silk thread and handed it to the maid beside her, "Be sure to hand it to Li Chengze in person." The maid respectfully took the letter, bowed slightly and left. After she left, Lin Qingya stood up, walked to the window, and looked at the towering palace in the distance with deep and calm eyes. She did not hand over all the evidence to Li Chengze, but only selectively leaked some information, which was enough to provoke the relationship between Li Chengqian and Li Chengze, but not enough for her to completely control the situation. She wanted to make this power struggle more exciting. She sighed softly, turned around, walked to the dressing table, and combed her hair in front of the bronze mirror.

Meanwhile, in another part of the imperial city, Li Chengze paced anxiously. He received a letter from Lin Qingya, which vaguely mentioned evidence that Li Chengqian colluded with certain ministers and intended to rebel, but that was not all. He clenched his fists, and a trace of viciousness flashed in his eyes. He longed for power and wanted to ascend to the highest position, and Lin Qingya seemed to be the key to help him. He believed that the evidence in Lin Qingya's hands could help him completely overthrow Li Chengqian and completely remove his stumbling blocks. Li Chengze walked to the desk, picked up a pen and wrote and drew on the paper, as if he was arranging some kind of plan. After finishing writing, he threw the pen on the table fiercely with a muffled sound, "Get ready, tomorrow morning..." He whispered to the guard, his tone carrying an unquestionable command.

Li Rui sat alone in the tea room, a cup of tea in front of him was slightly steaming, but he didn't think about it. He received Lin Qingya's letter and knew that she had started to act, and he also knew how much risk it was accompanied by. He put down the teacup, stood up and walked to the window, looking at the quiet night in the distance, he felt mixed emotions. He knew that Lin Qingya's plan was not just a simple power struggle, she had deeper considerations, and he could only stand behind her silently to protect her. He closed his eyes, took a long breath, turned and walked to the study, picked up a pen, and began to organize the intelligence.

Far away in the East Palace, Li Chengqian was still immersed in his anger towards Lin Qingya. He never thought that this seemingly weak woman would resort to such cruel means. He violently threw the teacup in his hand on her, and the porcelain pieces splashed everywhere. His roar echoed in the palace, but there was no response. He collapsed on the chair without any power. He had lost the initiative. The situation was getting more and more out of control. He could only watch his power slip away bit by bit. He clenched his fists tightly, his knuckles turned white, and the hatred in his heart was hard to eliminate.

Li Chengze secretly collected evidence according to Lin Qingya's instructions. He mobilized his hands and searched all over the palace, from the idle chats of the palace maids to the private letters of the ministers, from the subtle changes in the account books to the secret meetings late at night. However, even so, he only found some of the evidence mentioned in Lin Qingya's letter, and he could not find any definite evidence about the whereabouts and conversations of some key objects. Li Chengze rubbed his eyebrows irritably. There were a lot of files and letters scattered in the study, and the candlelight cast a heavy shadow on his tired face. He realized that the clues provided by Lin Qingya were just the tip of the iceberg, and the real secrets were hidden deeper, far beyond his imagination.

In order to get more information, Li Chengze decided to take action. He sent a generous gift to Lin Qingya, and attached a handwritten letter to express his intention. "Ms. Lin, I know that you are very talented and have served the country. This small gift is not a respect, but I hope you will accept it. Some things are difficult to deal with in time alone, and perhaps it will be more efficient to work together." Although the words in the letter were polite, the tone was sincere, and deliberately showed recognition and respect for Lin Qingya's ability. Li Chengze put down the brush, and his eyes flashed with subtle calculations: instead of passively accepting, it is better to take the initiative to find out Lin Qingya's true intentions and the upper limit of her ability.

After receiving the gift and letter, Lin Qingya just smiled faintly and did not comment. She told the maid to put the gift away, "Write back and say that this lady is cautious and does not want to be easily believed." After the maid left, Lin Qingya unfolded the letter and read it carefully. She picked up the teacup on the table and sipped the tea gently, her eyes as sharp as a hawk. She did not respond directly to Li Chengze's goodwill, but secretly dispatched people to monitor her actions and continue to collect more evidence. Li Chengze's goodwill was expected by her.

In the following days, a power game between the two of them was surging and intensifying. Li Chengze seemed to be in perfect harmony with Lin Qingya, but in fact he was testing her everywhere, trying to find flaws in her words and deeds; Lin Qingya remained calm and played along with him. Every response was just right, not letting him see the flaws, but also leading him into the trap he set. Li Chengze gradually discovered that Lin Qingya seemed to have anticipated his actions, and all his tests were easily resolved by her, and even controlled and guided by him in return.

In the end, Li Chengze found that he was being played around by Lin Qingya. Those so-called cooperations were just traps carefully designed by the other party. The carefully woven plans and clues were transparent in front of Lin Qingya, and there was no secret at all. Li Chengze's face was livid, and he gritted his teeth. Everything he had carefully planned was easily disintegrated by Lin Qingya. The reputation and plans he had accumulated over the years were teased by the other party with contempt, which made him lose all his face.

Lin Qingya took this opportunity to publish the evidence collected by Li Chengze to the court and the public, completely destroying the Crown Prince Li Chengqian's plan to seize the throne. For a while, the court was full of discussions and the whole court was shocked. Lin Qingya watched all this calmly. She knew the cruelty and helplessness of power, but she always maintained a clear mind and firm belief, and walked towards her own goal step by step. She put down the teacup in her hand, stood up and walked to the window, looking at the blue sky outside the palace.
