"What do you mean?" A bright color flashed in Ma Shichao's eyes, as if he had grasped some key points, and seemed to have missed something, with a look of uncertainty, he asked slowly.

"The eldest princess's concubine is now a taboo, from the dignitaries and nobles, to the peddlers and pawns are not allowed to mention the eldest princess and the horse at will, the horse has returned to dust, but the eldest princess is still in the palace, although it is not treated by the emperor on the surface, but in fact it is not, the emperor has always felt guilty about the eldest princess in his heart, so he is reluctant to visit the eldest princess, but in his heart he always pays attention to the bits and pieces of the eldest princess." Shen Yan pondered for a moment, glanced at Ma Shichao lightly, and then a positive color appeared on his face, and he deliberately lowered his voice and said.

"Although the emperor doesn't see the eldest princess, Princess Yuhan will chat with the eldest princess almost every day, and Princess Yuhan is the pearl in the emperor's heart, and she is the emperor's favorite princess. Shen Yan smiled faintly and continued.

"My lord means that the emperor uses Princess Yuhan's eyes and mouth to know everything about the eldest princess?" Ma Shichao's eyes lit up, and he seemed to think of the key.

"Not bad." Shen Yan nodded lightly, glanced at Ma Shichao, and said slowly with a hint of approval.

"Who is the most trusted person of the eldest princess and the horse, one is his scholar, and the other is the maid who serves him, and Zhen Xuansang is the younger brother of the eldest princess and the concubine, although he is not the most trusted person of the concubine, but no one can guarantee that Zhen Xuansang does not know some unknown secrets of the eldest princess and the horse, so all forces will want to fish out these secrets from Zhen Xuansang's mouth, or extinguish them and let these secrets disappear forever." When Shen Yan said this, his brows furrowed slightly, this is just one reason for the hot potato, and there is a more important reason, which is the emperor's attitude towards this matter, after all, the eldest princess and the horse were involved in the original public case.

"A very critical question, except for the eldest princess in the Horse Mansion, it can be said that there was no living mouth left, why did this Zhen Xuansang survive, is it because Zhen Xuansang is not in the Horse Mansion, or is there another reason, if this problem is not understood in advance and rashly talks to Zhen Xuansang, maybe it will not be able to break Zhen Xuansang's mental defense line at all, or he will not be able to grasp the initiative." Shen Yan thought about it, and the thoughts in his mind seemed to become clearer, although his brows were still slightly furrowed, but his words were mixed with an indifferent confidence.

"Your Excellency already has the answer in your heart?" Seeing Shen Yan's expression, a flash of brightness flashed in Ma Shichao's eyes.

"I can't talk about the answer yet, I won't know the details until I talk to Zhen Xuansang." A hearty smile appeared on the corner of Shen Yan's mouth, and he said lightly.

"When are you going to talk to Zhen Xuansang?" A faint smile appeared on the corner of Ma Shichao's mouth.

"Not yet, wait until I know more about Zhen Xuansang's background and sort out my thoughts." A faint but confident smile appeared on the corner of Shen Yan's mouth, and he said slowly.

"Although it is unknown what Gonggong Xu talked about with Zhen Xuansang, it is not difficult to guess, the most important thing is to know the emperor's attitude towards this matter, and this is not only difficult to guess, but more importantly, this matter cannot be asked to the emperor openly, so you can only guess the emperor's mind through some other ways."

"Shengwei is unpredictable, once it comes to the emperor's attitude, it is indeed very tricky." Hearing Shen Yan's words, Ma Shichao nodded slightly and said lightly.

"So where do you plan to start?" Ma Shichao asked thoughtfully.

"Is there any news about the eldest princess and the eldest princess's concubine mansion here from the Jinyi School?" Shen Yan thought for a moment, then his face showed a touch of indifference, and he asked slowly.

"There seems to be news about this in the impression of the subordinates, but it is regarded as taboo by Guo Bianxuan, so no one in the Jinyi School knows except Guo Bianxuan, and the subordinates need to take some time to find out." Ma Shichao thought about it for a while, and seemed to have this impression in his mind, but if he wanted to find this file all of a sudden, he really didn't know where to start, so he needed a little time to search Guo Bianxuan's previous office to see if he could find it.

Ma Shichao was not worried about the destruction of this file when Guo Bianxuan was arrested, because Shen Yan could be said to have arrested Guo Bianxuan without warning, it was sudden, so Guo Bianxuan simply did not have enough time to destroy some important files, and even some files became important evidence for sanctioning Guo Bianxuan, which may be because Guo Bianxuan felt that the Yamen of Jinyi School was his territory and was absolutely safe, but what he didn't expect was that he dug the pit to bury himself.

"Well, Guo Bianxuan's office space is still in a forbidden area, originally I wanted to wait until I was completely free to tidy up there, but now it seems that this gives us a chance, you go and search carefully, and see if there are any other gains in addition to this convenient file." An indifferent smile appeared on the corner of Shen Yan's mouth, glanced at Ma Shichao, and said slowly with a hint and encouragement.

"My subordinates understood." Seeing Shen Yan's hint, a smile appeared on the corner of Ma Shichao's mouth, bowed slightly, and said softly.

"Zhen Xuansang was an accident, or was it a game deliberately set up by someone with a heart?" Looking at Ma Shichao's departing figure, Shen Yan's brows furrowed slightly, swept away the faint but confident smile before, and kept thinking about various possibilities in his mind, just as everyone wondered, why did Zhen Xuansang have that token in his hand, and how did he escape from the surrounded Lingnan, and come to Jinling and break into the palace all the way?

If it's just an accidental phenomenon, then it's better, this problem is not particularly tricky, at most you need to take into account the emperor's feelings and attitudes, but if all this is a game set up by someone with a heart, then who is behind the scenes, what is his motive, or who is his goal?

If this suspicion is not clarified, will Shen Yan rashly insert himself into this matter, will he become a pawn of this mastermind behind the scenes? Or will it be the target of his attack?

Shen Yan's brows kept furrowing, and he kept thinking about various possibilities in his mind, but he was overturned one by one by himself.
