"It's a bit chilly here, don't stay outside for too long or you might catch a cold."

"Well, let's go inside then."

He Tiantian nodded sweetly.

Two people entered the ancient castle, with a bodyguard carrying their luggage behind them.

As soon as she stepped into the ancient castle, He TanTan's cell phone rang.

The phone call was from the restaurant manager. He sweetly took out her phone and looked at it, then answered with some surprise: “Hello?”

She had told me before she left that if there wasn't anything important, it would be best not to call her and Xixi for the next period of time.

I didn't expect that as soon as I got here, the phone call came. I don't know what happened.

"Miss Sweet, something's wrong, we just had a rat appear in the restaurant…" The manager's voice on the phone was clearly panicked.

"What?" He Tiantian couldn't quite believe her ears, "There were rats in the restaurant?"

"Uh-huh," the manager nodded like a chicken pecking at rice, his face pale with panic. "Just discovered it now. All the customers in the restaurant are terrified, and some are even calling relevant departments to come over and revoke our business license..."

He Tiantian was instantly overwhelmed. She really wanted to rush out, but she was in Europe now, which was obviously impossible.

"Call Ye Xuan immediately and have him take care of it!"

The restaurant manager answered and then quickly hung up the phone.

Put down her phone, He Tiantian's brows furrowed.

Ye Zi Rui sensed something was wrong: "What happened?"

"There was actually a mouse in the restaurant, I don't know how that happened..." He Tan sweetly told Ye Ziyu about what had happened.

"How is that possible?" Ye ZiRui's sword brows furrowed as well. "The restaurant's hygiene conditions are very good, it shouldn't happen like this logically. It's most likely someone deliberately making trouble."

"Intentionally causing trouble?" He TanTan suddenly understood, "You mean someone put rats in the restaurant?"

"Maybe so." Ye Ziru pondered for a moment, took out his phone and dialed a number, sending someone to investigate.

After investigation, the restaurant found nothing unusual besides the rat.

Yún Qíng xī did not know about this, Yè Zǐyù purposely did not have anyone tell her.

He didn't want XiXi's mood to be affected by this, so he handed the matter over to Ye Xuan.

"You must find out the truth and make sure that XiXi's restaurant doesn't have to close because of this..." Yu FeiFei was very concerned about the matter and offered to investigate with Ye Xuan.

She doesn't spend a lot of time with Ye Xuan on a daily basis. Ye Xuan has to take care of the big and small matters of the Xuan Mei, only having free time after work to accompany her.

Being able to be with Yu Fei Fei during work hours naturally made him happy.

It's just that something happened at the restaurant, and it's really not something to be happy about.

"I think it's possible that someone saw how well the restaurant was doing and felt jealous, so they came up with this scheme," Yu Feifei speculated.

Ye Xuan nodded in agreement: "There are already several thriving restaurants on this street. Let's start our investigation with these stores."

He went through each store's information one by one and discovered that one of them actually belonged to Pei Xin Dong.

"I wonder if the Pei family is involved in this somehow..." he mused.

"The Pei family?" Yu Feifei sounded confused, "Which Pei family?"

Ye Xuan then briefly told Yu Feifei about the grievances between the Pei family and the Ye family.

So, it's not that these two actually have a deep grudge against each other? It's just that Pei Xindong is messed up in the head and insists on targeting Shao Yu everywhere?" Yu Feifei asked.

Ye Xuan nodded. "Well, that can be said."

Yu Feifei became even more puzzled. Her intuition told her something was amiss: "No one would suddenly target another person for no reason... There must be a reason... Wait, didn't you say that Pei Xindong's girlfriend Yu Qian had a conflict with XiXi before?"

“There was a history between them, but it wasn’t anything major. They had just met a few times in the shopping mall. At first, Yu Qian was quite arrogant and even threatened to have security throw Miss Xi out. In the end, she was forced to apologize.” Ye Xuan said.

Yu Feifei immediately understood: "I think it's most likely this woman who is playing tricks. People like her have hearts so small and petty, after being slapped in the face by Xi Xi once, she must be brooding and wanting to get revenge immediately!"

Ye Xuan suddenly felt that she made sense: "So... do you think this time, it might be Yu Qian or Pei Xin Dong's idea?"

"Well," Yu Feifei nodded, but wasn't entirely convinced. "It's not enough to just theorize without evidence, so you're going to have to step up now."

"Alright, leave it to me from now on." Ye Xuan reassured her.

Two private detectives sent by Young Master Yu arrived at the restaurant soon.

The private investigator was having his first ever case dealing with a mouse. He stared at the trapped rodent, now confined within a cage, as he met eyes with Yexuan.

Finally, it was Ye Xuan who broke the silence first: "I suspect this rat was deliberately brought in."

"Maybe we should check the security footage first." the detective suggested.

Then the two of them watched the surveillance footage and found that the place where the mouse was first discovered was the bathroom.

"This isn't logical," the detective furrowed his brow, "Mice usually stay where there's food; it's unlikely they'd be found in a bathroom."

"So, could someone have put the rat in the bathroom on purpose, waiting for someone to find it?" Yu Feifei's little head poked closer.

"It's possible..." the detective nodded, "but that would make things more difficult to investigate."

After all, there are no cameras in the bathroom, so it's impossible to know who did it.

"Xuan Ge, this is the information on everyone who came in and out of the restaurant today." Xiao Liu arrived at some point and handed Ye Xuan a thick file bag.

Yu Fei Fei couldn't help but be surprised.

With such a booming business, over a hundred people came in and out of the restaurant throughout the day. How could so much data from so many people be collected so quickly?

"Have we missed anything?" Ye Xuan asked.

Little Six shook his head: "Nothing is missing, all the data of people captured by the surveillance cameras are here."

The surveillance camera is positioned at the front door, so anyone entering the restaurant will be captured on film.

Ye Xuan handed the information to the private investigator: "Get a few people to investigate this."

With so much data, one person obviously couldn't finish going through it all in a short time. The detective took it and quickly called over his own detectives.

This detective agency belongs to the Ye family. They were also responsible for investigating the incident where Ye Ziyān fell into the water before.

After eliminating several suspects, the main focus shifted to five individuals.

These five people went into the men's restroom before they discovered the mouse. One person stayed in there for an unusually long time.

"This man named He Xiong, is he an employee of Peixin Winter Company?" Ye Xuan stared at one of the files, frowning.
