Tie Wandao asked: "What if there is no problem? Will the circle still appear?"

Li Pingrun shook his head and said, "That won't be."

"Can the black circle be removed then?" Tie Wandao asked.

"That's a trace, I have to paint something outside the wall and cover it." Li Pingrun said.

"What if the wall is ground thin, can it be removed?" Tie Wandao asked.

"It's not impossible, but it's not easy." Li Pingrun said, "The color of the circle will seep into the wall and will not seep too lightly. If it is ground, it will probably have to be ground very deep."

"Why is this so? What's the name of what you want to set up?" Tie Wandao asked.

"It's called the 'monitor'." Li Pingrun said.

Tie Wandao asked: "You just said that if there is no problem, the circle will not appear. Will the surveillance item itself be seen?"

"I can't see it." Li Pingrun said, "Unless someone who knows how to do it deliberately uses spells to test whether there is a surveillance item here."

Tie Wandao said: "If someone uses spell to detect that there is a surveillance item here, can such a person erase the things recorded in the surveillance item?"

"It cannot be erased." Li Pingrun said, "Even if the surveillance item is destroyed, the recorded situation before it is destroyed cannot be erased."

"That's strange. All things have been destroyed. Can the situation recorded before be kept?" Tie Wandao asked.

"Class leader, this is the case. The surveillance project is just a matter of me using magic in the basement. When the things it records will be recorded, it will be transmitted to something called "Sighting Fan". The surveillance server is here. Even if there is a problem with the surveillance project, the surveillance server will not affect it." Li Pingrun said.

"If something happens, you want to see the situation recorded in the surveillance project, even when the surveillance project is recorded, you can see it from the sightseeing fan?" Tie Wandao asked.

"If I knew something special was happening in advance, I would indeed see it." Li Pingrun said.

"In this way, if you set this thing in one place, then if there is a special situation in that place, you will be able to grasp it soon?" Tie Wandao asked.

"Yes, but I can't know in advance when a special situation occurred in a place." Li Pingrun said, "I can't stare at the sightseeing fan every moment."

"Why can't you stare?" Tie Wandao asked.

"The long time I have seen the sightseeing fan will have a negative impact on both eyes." Li Pingrun said.

"Oh, isn't it just a look at something? How much negative impact can it have?" Tie Wandao said, "Can't you keep staring at me?"

"If I hadn't had any special circumstances, I kept staring at it. If the injury was serious, my eyes might be blind!" Li Pingrun said, "I used to be a priest who was blind because of this."

"When I looked at it, how different it was?" Tie Wandao said, "Didn't you say you don't know when a special situation occurred? Then when you look at the sightseeing fan, don't you also have to read the surveillance record from beginning to end?"

Li Pingrun said: "I won't read it from beginning to end. I will first test whether the situation recorded in the previous period of time is not included in the monitoring and recording. Although if I was not testing when a special situation is born, I will definitely not know that it has been born, but if I use the method to test it through practice, I can know whether the situation recorded in it contains some special situations."
