After going downstairs, Officer Gao was still questioning her. Gu Xin looked around but didn't see the waiter from before. She frowned and walked towards Li Yuyan.

"Miss Li, could you please stand up for a moment?" Gu Xin said.

She told me to look carefully, otherwise I'd make a fool of myself later.

Li Yuyan looked blankly at Gu Xin. Her maid nudged her, and she stood up in a daze.

Gu Xin looked at Li Yuyan's front, then asked her to turn around, and then observed her back.

Apart from the bloodstains on her feet and the hem of her skirt, there wasn't a single trace of blood on her body. Even the hands holding the dagger were spotless, except for the sleeves.

Gu Xin asked Li Yuyan to sit down, then went to the shopkeeper's side and asked, "Shopkeeper, are all the workers here today?"

The shopkeeper looked around, counted, and then nodded: "Princess Xinxin, all the staff who worked in the shop this morning are here."

Gu Xin frowned: "No, there's still one person missing. I just asked him to go downstairs and inform you that the waiter isn't here."

The shopkeeper then looked at the shop assistants inside the shop, and someone immediately stepped forward: "Shopkeeper, it might be A-Wang. This morning, I took my mother to the hospital for a check-up and asked A-Wang to cover for me. I just thanked A-Wang."

Gu Xin turned to look at the man: "What about Awang?"

The man said, "Awang went back, he left from the backyard. I was called to the front by the other guys as soon as he left."

Gu Xin sighed: "Officer Gao, that Awang is highly suspicious. You should send someone to arrest him immediately."

Officer Gao looked at the shopkeeper: "Was Awang really in the shop just now?"

The shopkeeper was still in shock and hadn't reacted yet, so it was Ah Wang who answered the question for him.

The waiter also revealed other information: "Princess, Constable, the deceased upstairs is indeed a maid of the Jiang family. Ah Wang really knows a maid of the Jiang family. Ah Wang is from Jiangnan. He said he came to find his cousin and rented a house in my house. Later, he said he found his cousin and that he might go to work for the Jiang family and get married to his cousin."

Officer Gao was shocked and quickly ordered his men to follow Xiao Er to his house to arrest Awang. Although it was very likely that they would not be able to catch him, they still had to go and see.

Officer Gao asked Gu Xin, "How did the princess know that Awang was a suspect?"

At this moment, Lu Ni and Jiang Hong arrived with their maids.

"Lu Ni, Jiang Hong, quickly tell the constable that I really did agree to come here with you, I really didn't kill anyone." Li Yuyan rushed over as if she had seen a savior.

Lu Ni and Jiang Hong stepped back together, and Li Yuyan almost fell, but Gu Xin helped her up.

"Yu Yan, what are you talking about? When did we make an appointment with you? And it's only morning, we're still sleeping at home," Lu Ni said.

“Yes! Why did you call Xiao Cui to the teahouse in private? Why did you kill Xiao Cui?” Jiang Hong also asked.

Li Yuyan stared at the two in disbelief. It was clearly Lu Ni and Jiang Hong who had arranged to meet her. Because of what happened yesterday, they had been caught by someone, and the three of them had agreed to meet at this teahouse to discuss their next move.

That's why we made the appointment here – it's because this teahouse is less crowded in the morning. Why won't they admit it?

Gu Xin immediately realized that Li Yuyan was not lying, but Jiang Hong and Lu Ni were.

Jiang Hong and Lu Ni probably don't know that a suspect has been found here. They think that Li Yuyan is caught red-handed because he has a knife! If they don't admit it, no one will believe Li Yuyan no matter what he says after he kills someone.
