Red Silk hid on the roof, watching the man in black cross the roof in the mansion and head towards the courtyard to the east. She remembered that it was the courtyard where Xiao Yuanshan lived, and it seemed that the thief was still very clear.

When Hongxuan was about to leave, Xiao Ziming walked out of the secret room, and the bookshelf returned to its original state.

After Xiao Ziming left, Hongxuan hung upside down under the eaves, making sure that no one else was approaching, and then he dodged into the study.

The study looks no different from the ordinary study, if you don't know that the washing on the table is the mechanism, I'm afraid it will be difficult to find the secret room behind the bookshelf.

Hongqi walked to the desk, turned the water on the desk, and then flashed into the secret room.

The secret room is not big, there are two bookshelves inside, and the bookshelves are placed with some title deeds of the grange shop, as well as some antiques, calligraphy and paintings, and books or something.

Behind those books, there was a small wooden box, and when I opened the box, I saw that there were more than a dozen letters neatly arranged inside.

At the seal of the envelope, there is also a seal with an eagle pattern, which is a evidence of the Xiao family's correspondence with others.

The gong was still ringing outside, and Hongqi didn't dare to stay longer, so he took the letters in the wooden box and took two letters from the middle, and restored everything to its original state.

Just as Hongqi was about to leave, she heard a sound of footsteps, Hongqi frowned slightly, her heart was not good, and the man in black walked towards this side.

If you go out now, maybe you just bump into the man in black, so let's hide first.

Thinking of this, the red silk flew on the beam of the roof, the beam was very wide, and he wanted to hide it, and he was in black clothes, as long as he didn't check it deliberately, it was not easy to be discovered.

Through the window paper, a dark figure can be seen running past the window. Immediately afterwards, a group of family members in the house chased after them with lanterns.

After Hongxuan and the others walked away, she quietly walked out of the room and disappeared into the night.

After a stick of incense, Hongxuan changed into the clothes of the steward of the East Palace and returned to Gu Yunxin's side.

"Master, master, the slave found this from Xiao Ziming's secret room in his study." With that, Hongxuan handed the letter into the hands of the prince.

The prince flipped through the letter in his hand, and of course saw the small eagle in the lower right corner of the envelope.

This flying eagle pattern is the mark of Beiliang's secret agent, which shows that Xiao Yuanshan does have dealings with Beiliang, and Xiao Ziming has always known about it.

"Master, is there anything wrong?" Gu Yunxin wondered.

"No, this flying eagle mark is a mark used by Beiliang secret agents to communicate news, and it is difficult for outsiders to pretend to be it." The prince said lightly.

Gu Yunxin looked at the inconspicuous flying eagle mark on the envelope, and then said lightly: "Is this mark really difficult to impersonate?" I don't think there's anything special about it. ”

Seeing Gu Yunxin's studious appearance, the prince hooked his lips slightly, and said softly: "The lady doesn't know, this seems to be a flying eagle pattern, but if you use a magnifying glass to look at it, you will see other things, and even if the seal is impersonated, the code words in the letter will not be so easy to unravel for a while." ”

"What? There are even code words in this? Wouldn't that be a wasted effort? Gu Yunxin said a little discouraged.

originally thought that she had finally found evidence of the Xiao family's treason, but now that she heard the prince say this, she felt that it was very likely that such a lot of effort would be wasted, and she felt very uncomfortable.

"It won't be in vain, just with the payment before and after, it is enough to prove that Xiao Yuanshan is involved with Bei Liang, no matter what they mentioned in the letter or not, it doesn't matter anymore." The prince said lightly.

Suddenly, something seemed to sound from the red silk, "Master, when the slave maid was in Xiao's house, there was a man in black who went straight to Xiao Yuanshan's courtyard and, later, he ran to Xiao Ziming's side, but he was chased by the family all the time, and I don't know who it is." ”

"Oh? How is that man's kung fu? The prince curled his lips slightly.

Hongxuan thought about it slightly, pursed her lips and said disdainfully: "If you go back to your master, that person's martial arts don't know, but you can't do light skills, and you will be chased all over the yard." ”

"Perhaps, he just wants to play tricks on those family members, get their attention, so that he can help others cover up." The prince raised an eyebrow on one side and said.

If it was just an ordinary snitch, then how could he run from Xiao Yuanshan's yard to Xiao Ziming's yard again? At least if he can't steal anything, he'll have to get out first. A snitch who knows martial arts, will he still be afraid of a few family members?

"Master, my subordinates are sure that when my subordinates were in Xiao Ziming's courtyard, they didn't find other people hiding in the shadows. Could that person just test the truth first? Hongxuan said lightly.

"Well, it's a possibility. You go down and rest first, you won't have to be on duty tonight. The prince said lightly.

"Yes." Hongxuan bowed and withdrew.

Hongxuan went down to rest, Mo Feng and the others were still in the courtyard, the prince didn't feel sleepy, things in the palace were a mess, Yun Zheng was busy detoxifying the Xiao family and the Xianwang, even if the Xiao family was at fault, then she should be allowed to accept the sanctions of the national law in a sober state, instead of going crazy and stupid to end this life.

Thinking of this, the prince turned his head to Gu Yunxin and said, "Lady, I'm going to find Yun Zheng to see the situation of the Xiao family and King Xian, you rest early, don't work too hard." ”

"Well, you'll be back sooner, then." Gu Yunxin said lightly.

Many people are very envious of the relationship between Gu Yunxin and the crown prince, because, between the two of them, the way they get along is always equal.

The prince came to the courtyard where Yun Zheng lived and saw that he was busy boiling medicine, "Ah Zheng, you are still boiling medicine, just leave these things to the next person to do." Why do it yourself? ”

"There is no credible person, if someone does something with this medicine, it doesn't matter if my reputation is ruined, but if someone puts this accusation on your prince's head, it will not be good." Yun Zheng didn't look up, and continued to fan the carbon fire of the medicine furnace with a fan.

"Do you think there's someone behind this?" The prince lifted his robe and sat on the stone bench next to Yun Zheng.

"Isn't that obvious?" Yun Zheng shrugged his shoulders indifferently and said.

"That'...... Is their poison easy to solve? ”

"It's hard to explain, while I detoxify them, they continue to be poisoned, and it's another kind of poison." Yun Zheng frowned.

This is the first time he has encountered big trouble in so many years of practicing medicine. Detoxification is not so easy in the first place, not to mention, it is the poisoned person who continues to be in the rest

Poison, if this antidote clashes with the others, this person's life will really not be saved.

"Another poison in the end? It's been checked very carefully, and the meals are all made in the imperial dining room, if it's poisoned, isn't everyone else poisoned? The prince frowned.

"It's true that the people who deliver the food are staring very closely, and different people will deliver the food every day, and the candidates are all temporarily appointed, and it is not so easy to buy people to poison. What's the problem? Yun Zheng also said with a sad face.

"Then it's not clear, no matter what, save the lives of the Xiao family and the king first, and besides, I got this thing today, you can see." With that, the prince handed the two letters from his sleeve to Yun Zheng.

Yun Zheng saw the flying eagle mark in the lower right corner of the envelope at a glance. "This is the unique mark of the Beiliang secret agent, how did you get this?"

"It was found by Hongxuan when she went to Xiao Ziming's mansion. Therefore, this is the evidence of the Xiao family's treason, but the Xiao family can't die in a daze, there are some things I still want to ask to understand. The prince said in a deep voice.

Every time he thought of his mother and his unborn brother, who were killed by the Xiao family, his heart hurt very much.

Is it just to compete for favor? Although there are many ways to compete for favor in this harem, most of them are harmful to the other party who is deposed or sent to the cold palace, why do you have to take two lives?

"I don't think she would have said it even if she was sober. Even if you tell you, what can you do? The emperor has no feelings for her, she has always been thinking about Emperor Mu and Concubine Mu in her heart, and she also wants to have a place in the emperor's heart, even if that position is hate, she may be very willing. Yun Zheng said with a long breath.

"Let my father remember her for the rest of his life because he hates her? It's a dream. Why do they base their happiness on the suffering of others? After speaking, the prince hung his fist angrily on the stone table.

"Don't be angry, beware of being angry." After speaking, Yun Zheng stood up, walked to the room, took out a medicine bottle from the medicine box and handed it to the prince.

"What is this?" The prince wondered.

"It's a heart purifying pill, and it's reformulated on the basis of the poison pill. In addition to having a detoxifying effect, this pill can also make people feel good. Yun Zheng said lightly.

"Thank you, I'm really happy to have a brother like you for so many years. When I ascend the throne in the future, the imperial hospital will be handed over to you, right? ”

"Excuse me, it's good for me to be an ordinary doctor, I don't want to get too involved in the affairs of the palace." Yun Zheng hurriedly waved his hand.

"Why? What are you worried about? The prince said displeased.

"You and I are friends like this, it's good to be brothers, as for you to be the emperor and I to be the imperial hospital, that is the relationship between the monarch and the minister." Yun Zheng said lightly.

In fact, the prince had already guessed that Yun Zheng was such an arrogant person, he had never been willing to get involved in the affairs of the royal family, but for the sake of his friend, he made an exception again and again, and it was really a little too difficult for him.

"Well, since you don't want to, then I won't force it. However, if you stay in Kyoto, I can find someone to drink with me and be willing to tell the truth. The prince smiled lightly.

"Okay, let's talk about it then." Yun Zheng said lightly.
