"Back to the official, the slave maid is called Qiuchen, and she is the personal maid of the lady", Qiuchen bowed down lightly and said.

"Were you by Madame's side all the time last night?"

Qiuchen frowned slightly and thought for a while, and said: "That's not true, the lord felt a little uncomfortable before the dinner yesterday, and said that he was guilty of an old problem, so he wrote a prescription and asked the person who helped on the counter to catch the medicine according to the prescription."

After the medicine was caught, the lord asked me to boil the medicine, and then the lord asked the kitchen to make a bowl of ice porridge, and the lord felt much better after drinking the ice porridge, and he didn't drink the medicine, so he went to the living room to greet the guests. ”

"Has anything unusual happened in this time?"

"Strange?" Qiuchen thought for a while, "It's nothing unusual, oh, that's right!" If you want to say something unusual, that is, when the master was with ice porridge, Laicai suddenly broke in, which startled us, and the master asked him what was the matter, he said that he went to the wrong room, and was reprimanded by the master! ”

"But then again, it's only been a short time since I came here, and it's not been a month yet, so it's normal to go to the wrong room."

After saying that, Qiuchen squinted at Laicai and laughed out loud, and then saw Cai standing there, and the expression on his face became extremely unnatural.

"What about you?" , The corners of Nie Xiaohu's mouth moved slightly, and he asked the manservant again.

"My name is Tianshun, and I am the personal servant of the master."

"Were you by Master Shen's side all the time last night?"

"Yes, I've always been by my lord's side, and I've never gone anywhere."

"Since you've been by Master Shen's side all along, you must have seen that ghost?"

"See", Tianshun nodded.

"Then tell me about the situation!"

"Yes! After yesterday's dinner, the lord invited the guests to the backyard to listen to the music, after Yuhe sang two songs, the lord suddenly felt a little uncomfortable, and whispered to me that his stomach hurt a little, maybe because he drank ice porridge and cooled his stomach.

In order not to sweep the guests, the lord called someone to set off fireworks, planning to take advantage of the fireworks to go to the toilet, but at this time the ghost appeared, followed by a burst of white smoke and fire, and when I opened my eyes again, the ghost had disappeared, and the lord also fell to the ground, and this is how it happened. ”

Nie Xiaohu paced back and forth for a few steps, and asked while thinking, "Who bought the fireworks, where did they buy them, and how much did they buy?" ”

"I went to buy the fireworks", Laifu hurriedly raised his hand, "Yesterday afternoon, the lord asked me to go to the Wang Ji fireworks shop to buy fireworks, a total of sixteen fireworks, the lord said that this number is auspicious." ”

"Little Maozi!"

"Tiger Head!"

"Go to the backyard and count how many fireworks have been set off."

"Understood!"

"Xiaohui, let's go, let's take a look around!"

Nie Xiaohu and Cao Xiaohui walked out of the front hall, and first came to the store facing the street, the store was about thirty square meters, and behind the counter was a row of medicine cabinets, and the medicine cabinets were densely packed with small drawers, and the names of medicinal materials were written on each small drawer.

Nie Xiaohu came to the counter, looked around, a piece of paper placed on the counter caught his attention, Nie Xiaohu picked up the paper and looked at it, it was a prescription, the name and dosage of five or six kinds of medicinal materials were written on it, and the signature below was Shen Jiasheng.

Nie Xiaohu stared at the prescription, an imperceptible smile flashed at the corner of his mouth, and he silently put the prescription away.

The two came to the backyard side room again, where the people lived, the side room was a total of two rows, east and west for the maids, and west for the male servants. Each row is divided into small single rooms, and a small wooden sign is hung on the door of each single room, which reads "Rain Lotus", "Winter Plum", "Blessing", "Fortune" and so on.

Nie Xiaohu came directly to the door of the room with "Laicai" hanging on it, pushed the door and walked in. The room is not large, there is a table on the left side of the door, a wooden bed in the corner on the right, a wardrobe in the corner on the other side, and several landscape paintings hanging on the wall above the wooden bed.

Nie Xiaohu first scanned the entire room, and was about to start searching, but stopped, his eyes fixed on the blank wall above the wooden bed.

"Brother Tiger, what are you looking at, is there anything wrong with this wall?" Cao Xiaohui said while knocking on the wall with her hand.

"Look", Nie Xiaohu pointed with his hand, what is the difference between this wall and the opposite one? ”

Cao Xiaohui frowned and looked at both sides, and suddenly her eyes lit up, "There are a few places on this wall that are whiter than others!" ”

Nie Xiaohu smiled slightly and nodded.

"The shape of this white place seems to be a painting", Cao Xiaohui said staring at the wall, "There must have been paintings, and there are nails on the wall, there are 1, 2, 3 in total, they are three paintings, and the paintings have been taken away!" ”

Cao Xiaohui counted, "But, what does this mean?" ”

Nie Xiaohu didn't answer Cao Xiaohui's question, but opened the wardrobe and said, "Check it carefully and see if there is anything special." ”

"Okay", Cao Xiaohui agreed, and began to search around.

"Brother Tiger, come and see!" , Cao Xiaohui pointed to the corner behind the door and said.

At this time, Nie Xiaohu was taking out a burden from under the bed, and when he heard Cao Xiaohui's call, he walked over with the baggage.

In the corner of the wall behind the door, leaning on a broom, Cao Xiaohui took the broom away, and in the corner of the wall was a pile of scraps of paper, mixed with a lot of black powder.

"As I expected!" , Nie Xiaohu said with a smile.

"What is this?" , Cao Xiaohui looked at the pile of shredded paper curiously.

Nie Xiaohu was happy, reached out and took out a fire fold from his arms, shook it in the air, the flame ignited, and Nie Xiaohu carefully brought the fire fold closer to a little black powder.

"Magnetic!" A puff of white smoke rose from it.

"Gunpowder!" , Cao Xiaohui blurted out, followed by patting her forehead, "I understand!" ”

Cao Xiaohui looked at Nie Xiaohu, her eyes flashing with excitement.

"Let's see what's in there!" , Nie Xiaohu opened the burden in his hand.

There were two small brushes in the baggage, one was full of ink and was a little hard, and the other was oily, and a strange smell on the brush went straight to the nostrils.
