As night fell, the Forbidden City was shrouded in silence. In Li Rui's study, the flickering candlelight illuminated his handsome face. He sat opposite Lin Qingya, with several secret letters and map fragments scattered on the table. Lin Qingya's slender fingers deftly pieced together the map and whispered, "These are evidence of Zhao Sisi's collusion with the Northern Frontier forces. I have disguised most of them as 'accidentally obtained' secret letters and are ready to present them to Your Majesty." Her tone was calm, but with unquestionable firmness. Li Rui stared at Lin Qingya with deep eyes. He admired her calmness and wisdom, and was even more attracted by her firm belief. In the study, the air was filled with the faint scent of ink and the subtle tacit understanding between the two.

Li Rui picked up one of the secret letters, carefully examined the handwriting and seal on it, and then gently put it back on the table. "This move will not only completely dispel His Majesty's concerns about Zhao Sisi, but also make him more convinced of your intentions and consolidate our position in the court." His tone was soft, and his eyes were shining with admiration. His fingertips touched the table lightly, making a slight sound, and then added: "At the same time, some of the evidence we secretly kept will become a bargaining chip to deal with potential threats in the future."

Lin Qingya nodded gently, with a barely perceptible smile on her lips, "Yes, it is always necessary to take precautions before they happen." She picked up the teacup gracefully, took a sip, and then put it down, picked up the pen and wrote something quickly on the paper. Her movements were neat and smooth, like flowing clouds and water. There was no other sound in the room except the sound of the pen tip rubbing against the paper.

The next morning after the secret letter was delivered, an anonymous secret letter was placed on Li Heng's desk. The sunlight shone through the window onto the memorial, which was shining with golden light. Li Heng unfolded the secret letter, his brows knitted, his face gradually gloomy, and he quickly read the contents of the secret letter. In the imperial study, the air was so heavy that it was almost suffocating, and only the rustling sound of Li Heng flipping through the memorial could be heard. After reading it, he slammed the table and said, "What a Zhao Sisi! How dare you have an affair with Beijiang!" His eyes were burning with anger, but mixed with a hint of indescribable complex emotions.

Wang Zhong stood aside, observing the emperor's expression, not daring to breathe. He noticed that the handwriting and paper of the secret letter were extremely ordinary, without any special features, which made His Majesty even more confused - who discovered Zhao Sisi's conspiracy? And why was it submitted anonymously? He coughed lightly and said in a low voice, "Your Majesty, this plan is ingenious. It has disintegrated Zhao Sisi's power in one fell swoop, and also made Lin Qingya more reliable in your heart." This made Li Heng more suspicious. He knew that Lin Qingya was not an ordinary person.

Li Heng was silent for a long time, and finally spoke slowly: "Put this secret letter away, and don't make this matter public for the time being." He pondered for a moment, and added, "Pass the order to thoroughly investigate Zhao Sisi and her backers!" His voice was low and full of unquestionable majesty.

At the same time, in Li Rui's mansion, Li Rui received a letter from Lin Qingya. The letter only contained a short sentence: "The plan was successful and the future troubles have been eliminated." He looked at the rising sun outside the window, his lips slightly raised, his eyes full of determination.

After Lin Qingya successfully overthrew Zhao Sisi, the court seemed calm, but undercurrents were surging. Li Heng admired Lin Qingya's personality more and more, but he was more vigilant about the power hidden behind her. He rubbed the anonymous secret letter that revealed Zhao Sisi's affair with Beijiang, and his fingertips gently stroked the slightly rough paper. The sun shone through the hollow window frames, casting mottled light and shadows on the ground. Li Heng's eyes were deep and sharp, as if he could see through this seemingly calm court. He whispered to the eunuch Wang Zhong beside him: "Secretly investigate Lin Qingya's background, and...her so-called 'mind reading'." Wang Zhong bowed and accepted the order, and withdrew, leaving Li Heng alone in the imperial study to ponder alone.

Li Chengqian admired Lin Qingya's intelligence on the surface, and even publicly praised her for removing a great hidden danger for the court. His words were gentle and polite, and his smile was sweet, as if the two had a close relationship. But when he returned to the East Palace, he threw the jade cup in his hand to the ground fiercely. The fragments were scattered all over the ground, but they could not express his anger and jealousy at the moment. "Mind reading... this damn woman!" He stood up suddenly, pacing back and forth, his face uncertain. The palace lights flickered, illuminating his distorted expression. "I must master this power! Otherwise, how can I sit firmly on the throne of the queen?" He whispered to himself, his eyes full of sinister and vicious light. He immediately summoned his confidants and secretly monitored Lin Qingya's every move.

At the same time, Li Rui's love for Lin Qingya grew. He cleared obstacles for her, secretly dealt with those who tried to harm Lin Qingya, and tried his best to cover up the fact that he took special care of Lin Qingya. When he received the good news from Lin Qingya, he just smiled faintly, but a trace of imperceptible tenderness flashed in the corner of his eyes. "Everything went according to plan." He murmured in a low voice and gently placed the memorial on the desk. He was alone in the study, looking at the bustling street scene outside the window, his eyes were deep and his thoughts were full. He knew that he had concealed some secrets, including the true relationship between him and Lin Qingya, and some unknown secrets of his family, which could become the fuse of future conflicts. But at this moment he just chose to remain silent and guard this hard-earned relationship.

However, the result of Li Heng's secret investigation made him even more uneasy. He found some clues that showed that the relationship between Li Rui and Lin Qingya was not as simple as it seemed on the surface. Some secret letters, some inexplicable coincidences... all of this pointed to a disturbing conclusion. Li Heng sat alone in the imperial study, holding the secret report presented by the secret guard in his hand, his face terribly gloomy. The candlelight cast a cold shadow on his face. He slowly stroked his lower body, with a hint of fierceness in his eyes, "Li Rui... What on earth are you hiding?" He whispered to himself, his voice full of suppressed anger. This sudden discovery made the situation in the court even more confusing, and the power struggle even more complicated and fierce. Li Heng slowly raised his eyes, his eyes filled with the calm before the storm.
