Suihua Palace is the place where Concubine Zhuo Hui used to live, and later because she made some mistakes, which led to her falling out of favor, and finally, in the Suihua Palace, she committed suicide by hanging the beam, and since then Suihua Palace has been idle.

Later, it became the so-called cold palace, and all those who were not favored by the emperor, or who had made big mistakes, would be sent to Suihua Palace.

"There is such a big thing, you still have the leisure to report to me here, let me go, call the others, let's go to the Suihua Palace to have a look, the cold palace is forbidden, not anyone can break in!"

The chief guard seemed to be an anxious man, and when he heard Lu Mingyi's report, he didn't even have time to close the door, so he started directly, jumped onto the wall, and swept away in the direction of Suihua Palace.

For the sake of safety, Yin Qi'an hid in the grass for a while, making sure that there was no one around, and the chief guard did not return, so he boldly entered the chief guard's house.

Just in case, he left the window open to the south so that he could escape at any time.

The chief of the guard, it seems, should be writing a letter at this time, and there are only 12 words on it: the matter has been done, do you want to .........

Yin Qi'an's heart suddenly pinched at this moment, it seems that their plan is really not over, there should be other arrangements behind, if the situation told him by the national teacher before was not wrong, now there are still people dying outside every day, and there is an increasingly fierce posture, then what are they killing these irrelevant people for?

Is it just to please some psychopathic master? This inference was completely untenable to some extent, and when I looked through the envelope, I found that not a word was written on the envelope, which made it even more impossible to determine who the chief of the guard was working for.

Just as he was about to turn around and search for something else, Yin Qi'an's eyes glanced slightly, and found that something seemed to be sticking under the guard's desk, stretched out his hand, fumbled for it, and found that this thing was a letter.

Hurriedly took it down and opened it, there were only five words on it: don't act rashly, and at the place where the envelope was signed, there were only two words: Yunchen.

Yin Qi'an couldn't help frowning and thinking about it, logically speaking, it is impossible for the word Yunchen to appear in the palace, these two words are not from any harem, and the word is not the name of any emperor's relatives, so what does this Yunchen represent?

It's just a code name, and how did they deliver these letters?

It seems that as long as you figure out how the letter was passed between the two, you can confirm the culprit behind the monster murder case that happened in the capital recently, and Yin Qi'an's heart was slightly relieved when he thought that there had been a major progress in the case.

If it continues to develop at this rate, the one-month contract with the national teacher to solve the case will definitely end in his own victory.

As soon as the corners of his mouth hooked up a smile, he heard a trembling voice outside the door. Yin Qi'an hurriedly stuffed the letter back into it, glued it under the table, turned around and jumped out of the window, gently closed the window door, squatted under the window, and listened to the movement inside.

There was a slight sound of footsteps inside, obviously afraid that others would notice his presence, and the footsteps also stopped when they walked to the position of the desk, and then the sound of the paper being picked up was heard.
