In the wee hours of the morning, Dr. Asa delivered Chiba and Ash Hara to the door of the Tachibana Mansion.

"Kids, hurry back to sleep." Dr. Asa admonished. "Remember to lock the doors and windows."

"Hmm......" Qianyu pinched the bridge of her nose and nodded. Trapped to death...... You'll have to catch up on some sleep. ”

"Hmm-" Ash Hara yawned as well. "It's so sleepy......"

At this moment, Qian Yu suddenly heard the sound of squirming footsteps - from the intensity it seemed that it was not a human, but a small animal, I am afraid that it was......

The cat they had taken in ran past and stopped at Gray Yuan's side - before they left, they booked a cabin for the cat, and taught the cat to sleep in the cabin at night. And the cat has reached the age where it can eat fixed food, so Qianyu and they made an automatic feeding machine for the cat by hand and went out. (A tray modified from a balance and a food jar will trigger a mechanism to open the food jar and refill the tray when the tray contains a certain amount of cat food.) ）

"Did you wake up the little one?" Gray Yuan squatted down, smiled and touched the cat's head, but her expression suddenly froze, "Huh? ”

“？” The trace of sleepiness that Qian Yu had originally carried was instantly awakened by the surprise of Gray Yuan's mourning. "What's wrong?"

"It's ...... on its neck," Gray Hara said in a trembling voice. Scarred ......"

"I guess I was scratched by something, right? It's going to have to be checked to see if it's hurt. Qian Yu frowned, let go of the box in his hand, and also came to the cat, squatting down to check. It's-"

This wound looks like a strangulation mark, and it must be that something was tightly wrapped around the cat's neck to create such a scar.

But they hadn't found this scar on the cat's body before? And they haven't given the cat anything like that that would hurt it.

"Let's go back first," Qian Yu pursed her lips and said to Gray Plains. "Go back to your room first, it's safe there."

…………

After letting Gray Yuan Mourn go back to the house to rest, Qian Yu took the traceless umbrella and walked slowly in the courtyard. The visual assistance system and auditory assistance system of the auxiliary unit have been turned on at full power; Any received visuals and disturbances will be submitted directly to the auxiliary unit's computing system for troubleshooting, in case there are any hidden mechanisms or enemies.

There are no footprints on the land, so no one climbs over the wall – but if you do it from the main entrance, you can't do it...... Is it?

Chiba came to the gate and looked at the situation on the railing.

They hadn't cleaned the railing for more than ten days, and if someone did climb through the main entrance, even if the intruder was able to climb through the top of the gate covered with glass shards through the ladder, they would have to grab the railing and slide down, so the railing that the intruder grabbed must have been a little different from the other railings in terms of dust accumulation.

However, there is no ...... After comparing it, Chiba confirmed that the dust on the railing was completely in a normal state of deposit, and there was no sign of human invasion.

Is it just that you are too careful...... Qian Yu sighed, looked around for a week, and then turned around, ready to return to the residence.

Surveillance facilities need to be installed...... It's a scary feeling to face the fear of the unknown......

At this moment, Qian Yu suddenly noticed that the curtains upstairs had been opened—Gray Yuan was looking at him through the window, a little worried.

…………

"Did you find anything?" When Chiba returned to the house, Gray Plains asked.

"No," Qian Yu shook her head. "I've checked and there's nothing out of the ordinary, but I'm still going to get a set of surveillance probes to supplement the security measures."

"Do you think if someone comes to trouble us, will it be the organization's Vermouth, or the National Police Agency you told me?" Gray Yuan asked softly.

"What's wrong?" Thousand Feathers raised an eyebrow. "If you ask me, I guess it's probably the National Police Agency, after all, if you organize an operation over there, it will definitely touch Hoshino's intelligence network, and it's impossible for him not to inform me."

"It's okay......" Gray Yuan Wai shook his head.

"It's okay," Qian Yu comforted as she looked into Gray Hara's eyes. "It's going to be fine, trust me."

"But I'm worried," Gray Hara Ai also looked into Chiha's eyes. "You and I are in the same situation as spies—the day we are exposed, the day we die."

"It's okay," a smile squeezed into the corners of Chiha's mouth. "The police department must be coming for me, even if everything is closed, as long as you hide in the secret passage, you will definitely be fine."

"I'm not worried about myself, it's you!" Gray Plains suddenly interrupted Chiba's consolation. Immediately, she lowered her head, and Qian Yu couldn't see her expression.

"As long as you're safe," Qianyu's stunned expression lasted for a moment before changing to a smile again. "That's enough for me."

"I don't need to live on my own!" Gray Yuan Wai interrupted Chiba again, and there was a slight sobbing in her voice. "Either way, I hope you're doing well! That's my only expectation! ”

"......" Qianyu was stunned.

"......" Gray Yuan covered his face, as if he was adjusting his emotions, and it took a long time to sort out his emotions. Never mind...... Don't discuss this topic yet, it's almost dawn, let's catch up on sleep and regain energy. There will be a sports day after tomorrow. ”

…………

Qian Yu lay on the bed, thinking about the abnormal marks on the cat's body.

So what causes it?

———— at the same time, somewhere.

"This is obviously a good opportunity to search, why should you miss it?" Judy looked at Shuichi Akai and said dissatisfied. "Just get inside, we'll be able to conduct a detailed search and get the information we need!"

"That little imp had been prepared for this," Akai replied. "Our guys have handed out warnings, and there's already someone monitoring the search section."

"What?" Judy was stunned.

"That little imp is not simple." A hint of solemnity flashed in Akai Shuichi's gaze. "It's not easy."

———— at the same time, in another place.

[I've found their residence, and I think there's a very high probability that this is the correct address.] The woman's long, slender fingers tapped on the keyboard and sent out such an email.

After typing the email, the owner of the finger tore open a white bag of ice cream next to it.

[Give us a written report, and submit the data you used to infer this point to us for review, and if it passes, you can start work.] 】

"Hehe~" The corners of the woman's mouth hooked and she took out the ice cream in the bag. After a moment of friction with the nimble tongue on the milk ice cream, it left the ice cream with a cloud of milky liquid.
