Gu Yunru came back to her senses, stared at his face coldly, and snapped her fingers, "You have a jealous expression now, which means that what I said just now hurt you, right?"

As soon as these words came out, Cheng Shaoyuan almost sprayed the tea in his mouth onto her face. Gu Yunru quickly wiped her face, shrank her neck, frowned in disgust, and asked the waiter to bring some tissues.

"You can't do this even if you feel guilty. It's a waste of water!" Gu Yunru heaved a sigh of relief after wiping her face. Seeing that it was getting late, it was time to send Cheng Shaoyuan away, so that Rong Zhen wouldn't start nagging after he knew about it.

"I just want to say that your judgment may be wrong." Cheng Shaoyuan was stubborn and refused to admit that he did have some thoughts about her. He had buried this secret deep in his heart and would not allow anyone to reveal it!

"If you say it's a mistake, then it's a mistake. The clear will be clear and the turbid will be turbid. You have seen what my abilities are like." Gu Yunru raised her eyebrows at him unwillingly. Her psychology had no rivals in this era.

Gu Yunru came to a hasty conclusion about Cheng Shaoyuan's unconvinced look. It was obvious that his self-esteem was hurt, so he denied it.

When Rong Zhen finished his business and returned to Ruyi Inn, Cheng Shaoyuan had already left.

When she came, she prepared a set of night clothes for Gu Yunru to change into, so that she could blend into the Shangshu Mansion in the night and would not be discovered.

"Very efficient." Gu Yunru said as he came out from behind the screen and turned into a black firewood man.

The two of them sneaked to the vicinity of the Shangshu Mansion under the cover of night and found that the main door and the back door were closed tightly, and even a bird could not fly over. The wall of the Shangshu Mansion was so high that the top could not be seen at a glance.

"What should I do? I don't know how to do Qinggong." Gu Yunru took a step back in fear, but she didn't expect Rong Zhen to directly put his arm around her waist and carried her out like a kite, floating as if walking on the clouds.

She actually forgot that there was a martial arts master by her side. Every time he took her out like this, it was like experiencing skydiving for free, which made her feel a little proud.

"Ouch." Gu Yunru almost twisted her foot and suddenly bumped into his arms. The two of them walked closely together. Rong Zhen held his hand and told her to be careful. It would be embarrassing if they were discovered before they went in.

Gu Yunru didn't want to hold him back, so she pursed her lips tightly to prevent herself from making any sound. The two of them came to a nearby study and began to walk into the house.

The furnishings in the study are very simple, and there are a dizzying number of books on the cabinets. It seems that Lord Cui is really knowledgeable.

The two of them split up and began to search the study to see if there were any clues left behind.

Rong Zhen knew Lord Cui's usual personality very well. He was well-versed in the Four Books and Five Classics and spent most of his time in the study. If there were any clues left behind, they would only be discovered here.

Gu Yunru felt dizzy when reading the remarks of Mencius and Zhuangzi. The scholars of this era were really able to withstand pressure. After all, the imperial examination system was the only hope.

I looked through it and didn't find anything strange. I accidentally touched a book and didn't expect there was a button on the back.

She was startled and looked around furtively, then winked at Rong Zhen.

Rong Zhen also noticed that there was something wrong with her expression. When he was about to walk over, he suddenly heard footsteps approaching from the door.

"I seem to hear some noise in the study. Could it be that the master's soul has returned?!"

"Don't talk nonsense. Although today is the seventh day after the death of my father, I find it a little strange when you say that..."

It turned out that they were two servants. While patrolling, they heard some noise in the study and walked in curiously.

The two of them pushed open the door together, and saw that the room was empty, and there was no sign of mess on the table. They must have been overthinking.

Seeing a cat suddenly jump on them, the two were startled and looked shocked.

"It turned out to be a black cat."

"Yeah, I was scared to death!" The two servants left cursing. Gu Yunru and Rong Zhen came out from the desk. The two of them were very close to each other, cheek to cheek, and even their breathing became cautious. If they didn't leave, they would probably suffocate.

"Quick, there's something behind this book!" Gu Yunru was so excited as if she had discovered a new world. She led him to the bookcase and pressed the button, and found a secret compartment.

There was a piece of cloth in the secret compartment, and it seemed that there was something precious wrapped inside. As it was dark now, he couldn't see clearly what it was, so he just stuffed it into his chest and planned to observe it carefully when he returned home.

Just when the two were about to leave, they suddenly found a man in black slipping in. When the two stood face to face with the man in black, they were both shocked. Is this an expert against another expert?

"Are you here looking for something too?"

This work is organized and uploaded by Liujiu Book Bar~~

The man in black in front of him was extremely confused. He came here alone after receiving the order, so why were there two people here? Did the master order two other people to come and carry out the task?

"...Uh, yes, the thing has been found. Brother, this should be what you want!" Gu Yunru handed the thing in his hand to him. The man in black naturally had no idea whether the thing he handed over was real or fake, as long as the job was completed.

"I didn't expect you to get here first! Then I'll leave first." The man in black didn't seem to doubt the identities of the two men. He jumped onto the roof with his things.

Gu Yunru took a deep breath and patted her chest. No wonder Rong Zhen gave her a black nightgown, because he was afraid of meeting an expert.

"Let's go!" Gu Yunru had to take Rong Zhen away from this place of trouble before that guy could react.

The two successfully left the Shangshu Mansion.

After returning to the palace, Gu Yunru couldn't wait to open the contents. It turned out to be a letter of remonstrance, which was also handwritten by Lord Cui.

The above content shocked the two of them. It turned out that it was closely related to the Kappa incident. No wonder she always felt that this matter was not so simple and it was written into it by the Shangshu long ago.

Rong Zhen sat in front of the case, staring at the evidence in his hand with a worried look on his face. He then thought that the man in black must have also heard the news, so he came over to submit a letter of advice.

The man in black on the other side handed the letter of advice to Xie Yihui. When Xie Yihui saw that there was only a piece of rag inside, he became furious and threw the thing in his hand at Xie Yihui's head.

"Tell me what this is?!" Xie Yihui asked angrily, quite annoyed.
