Hearing Su Mu's words, Bao Fu Cheng nodded his head in agreement, "That's right, I also have the same intention. I must properly investigate and solve this case."

Although the decorations of the Zhu Residence were exquisite, the space it took up was not that big. After walking for a while, they arrived at the place the two of them needed to stay for the night.

Since Mrs Liu could not speak, she blessed the two of them before turning around and leaving.

Bao Zuisheng quickly walked to the front of the door and locked it. Su Mu looked around the room that wasn't too big or small. It was neat and clean, no different from the guest rooms of a large family.

After confirming the room was untouched, the two of them sat by the table and started chatting.

"That Seventh Madam of the County Magistrate's newly hired is really a peerless beauty!"

"That's right. If I had any luck, I would definitely die here."

When the people at the door heard their conversation, they quietly retreated.

Inside the room, Su Mu had already placed a piece of paper on the table. He took out a carbon pen from his sleeve and wrote on the paper, "Liu, something's wrong."

With regards to the problem with Mrs Liu, Bao Liusheng also nodded in agreement.

Just now, when Su Mu had purposely stopped to say that the culprit was still within the Zhu Residence, Mrs Liu, who was walking hurriedly in front of the two of them, clearly stopped when she heard this.

In other words, she was not a deaf mute like Zhu Chusheng had said.

As for why Zhu Chusheng said Mrs Liu was deaf and dumb, it was unclear whether it was Mrs Liu who was lying or Zhu Chusheng was lying.

In the afternoon, the two of them followed a servant sent by Zhu Chusheng and wandered around the Zhu Residence for a while, asking about things with vague words.

"How is your young master recently?" Bao Fu asked the attendant.

The green-robed manservant sighed and said with a frown, "Ever since the old mistress passed away, young master's body has been getting worse with each passing day. Business at home is not doing well either."

"The Zhu Clan has business?" Su Mu continued to ask with a hint of curiosity in his eyes.

The manservant scratched his head, "I'm not too sure either. I heard a few people who were working outside the courtyard say that the old master's business collapsed, and that he was in debt."

"Your young master is really pitiful, he lost his mother and has to busy himself with business." Bao Fu Cheng pretended to be sympathetic.

The attendant nodded in agreement, and his tone carried a trace of helplessness. "The Young Master is indeed pitiful. A person who treats others with the heart of a Bodhisattva, now it's really …" "Sigh."

"That is the residence of the madame. May I take a closer look?"

The latter stood up and stood in front with a helpless smile on his face. "I'm not going, after all, we just passed away not long ago, so we were really helpless before being assigned such a job. It's fine to just look around, but it'll be better to report it to the county magistrate when we get back."

The servant smiled and nodded, then turned around to take the two of them to another place.

After roughly memorizing the location of the Zhu Residence's courtyard, Su Mu was exhausted and wanted to head to the front hall to eat dinner with Zhu Chusheng. He carried his bag with him and hurriedly returned to the resting area.

"Why didn't you go to her house just now? Isn't that the crime scene?" Bao Fu Cheng asked in confusion.

Su Mu lightly tapped the corner of the table with his index finger, "The scene of the crime was left behind by the murderer. As long as the murderer is someone from the Zhu Residence, the evidence that should have been cleaned up would have already been tidied up.

"Then you don't want to go to the crime scene?" Ye Zichen was completely confused by what Bao Fu Cheng said.

Su Mu pondered for a moment before replying, "Let's go, but it's not the main point. The key point is to see what will happen in the Zhu Residence when night falls."

It was night and dark, and he could not see anyone, but he could clearly see the monsters and ghosts that were hidden during the day.

After a while, the door was knocked.

Since he didn't go to the front hall for food, Zhu Chusheng politely ordered people to bring the food over. The person who brought the food over was the suspicious looking Mrs Liu.

Upon seeing her, the two of them pretended to ignore her. Leaning back on the couch, they continued their conversation.

Mrs Liu, on the other hand, respectfully lowered her head. She arranged the dishes and soup neatly on the table and blessed herself in the direction where the two were resting.

It wasn't until Mrs Liu had obediently left the house that Bao Fu, with a single bound, arrived at the door. After he heard that there was no one around, he used an extremely soft voice to speak to Su Mu, "Brother Su, there's no need for this food. If there's a drug inside, you and I …."

"I have to." Su Mu explained, "Even if they did make a move, it wouldn't be at this moment. Moreover, there will be people coming back later to clean up. If they see that the food has not been eaten, it will only increase their suspicion."

Originally, Bao Fu Yun didn't really understand why Lin Yi would look at the two brothers. He had even used a bargaining chip like saving his own life to get them to help solve the case. Now that they had entered the Zhu Residence, Bao Fusheng could strongly feel Su Mu's alertness and thoroughness. Ye Zichen nodded in agreement, then sat down to eat.

As expected, after about an hour, Mrs Liu came back to clean up the dishes. Su Mu half closed his eyes as he laid on the bed not far away from the table to observe the dishes.

After Mrs Liu went down, Bao Fusheng and Su Mu walked together to the 'trap' that they had been waiting for.

At the table where they had just eaten, Su Mu had used a charcoal pen to write down the six words: "Wu Cheng Dreamland Tower". It wasn't small, but it was enough for a literate person to notice it.

When Liu Ma who was cleaning the dishes saw this, she couldn't help but slow down her hand movements and carefully observe the movements.

This Mrs Liu could actually read.

What kind of family, in the Great Yan Dynasty, would produce a literate servant, at the very least a scholar or a rich man, who valued his children's education, and who paid for a child of his own age to accompany him in his studies?

A rich family like the Zhu Family in Wu City was unable to raise a literate servant, and at the same time, Mrs Liu was not suitable to accompany Zhu Chusheng. Then he would contact the Zhu Family's background. Only the dead mother Zhu would meet the requirements.

In other words, Mrs Liu should be a maid brought by Mrs Zhu to accompany her mother. To a large extent, she was a reading maid brought here to accompany her mother. The two of them had learned how to read and write together. If that was the case, then Mrs Liu could not be deaf, and perhaps even this inability to speak was caused by the day after tomorrow.

Bao Fu Cheng subconsciously looked at Su Mu, who was deep in thought, and wanted to know what to do next.

Dusk was falling on Su Mu's nose, and the air was so still that one could hear insects chirping.

"Let's wait for nightfall." After a short while, Su Mu slowly spoke.

Seeing that the sky was getting darker, everyone started to get up.
