Early morning in Igwinte, on the apartment building on Nanyang Flower Road.
Grego, who had just gotten out of bed, got dressed and yawned as he pushed open his door. He entered the living room and didn't see his sister anywhere in the large room, but he didn't pay much attention. He went to wash up and then went to the door to get the breakfast prepared by Mrs. Hank downstairs.
He placed the breakfast on the table, ate a little casually, and then prepared to go out. Before leaving, he knocked on Dorothy's door and called out loudly.
"Get up, Dorothy, you'll be late if you don't get up now."
After calling out, Grego waited for a moment, but there was no response from behind the door. Seeing this, Grego turned the doorknob and opened Dorothy's door.
The door wasn't locked, and Grego pushed it open easily. What he saw was an empty room; the sheets were neatly made, the quilt was folded, the desk was clean and tidy, books were neatly arranged on the small bookshelf, and the clothes and schoolbag that were originally hanging on the hanger were gone.
"Heh... she's already gone? That's right... two pieces of her bread were missing just now. This child has been getting up so early recently. Is something going on?"
Closing Dorothy's empty room, Grego went back to drink a cup of milk before opening the door and going downstairs. He didn't think much about the situation, as the mornings had been almost like this for the past few days. His sister seemed to have become much more diligent recently, getting up earlier and leaving in more of a hurry than him.
'Perhaps I'll ask her tonight when she gets back if there's anything special going on at school.'
With this thought, Grego walked out of the apartment building and headed into the city at a very fast walking pace.
After nearly an hour of walking, Grego finally arrived at his workplace, located at the base of a tall building at an intersection. This ten-story building is called the Cypress Fir Building and is owned by the Igwinte city government. It was originally the location of the municipal building, but after the city government relocated, it was leased to several small companies as office space.
In fact, not all of Igwinte's government agencies moved out. In the basement of this building, the Prit Special Agency, the Prit National Security Secret Agency, Igwinte Branch, is still located here.
"Phew... another day of work... I hope there's no overtime..."
After sighing, Grego stepped directly into the building, a scene observed by a perspective from high up.
"She's ten minutes later than usual... Grego..."
On the rooftop of the building opposite the Cypress Fir Building, Dorothy sat behind a wall, observing Grego as he entered the building through the Corpse Puppet crows standing on the streetlights below. She murmured.
At this moment, Dorothy was sitting cross-legged on the empty rooftop ground. Scattered around her were a pile of papers with various patterns drawn on them with a pencil. Upon closer inspection, one could see that these were maps of the surrounding streets and floor plans of many buildings. Many points on these maps and floor plans were circled and marked.
Sitting on the ground, Dorothy picked up the scattered blueprints and began to examine them one by one. On each blueprint, she had marked the locations, such as the first and second floors of the Cypress Fir Building, the first floor and basement of the Wikken Building, Cypress Fir Street, Blue Fairy Grass Street, and so on...
These were detailed indoor and outdoor maps of the nearby streets, which Dorothy had drawn after conducting a carpet-like investigation using small animal Corpse Puppets over the past few days.
The purpose of these blueprints was to help Dorothy accurately locate the Igwinte Secret Agency and all of its entrances.
Yes, to catch the mole within the Igwinte Secret Agency, one must know who is in the An Yin Bureau, and the best way to do this is to directly use reconnaissance Corpse Puppets to infiltrate the An Yin Bureau, but this carries a very high risk.
In Dorothy's opinion, the headquarters of an An Yin Branch cannot be without means of counter-supernatural detection. If Dorothy controlled a Corpse Puppet created through supernatural means to enter the interior, it was very likely to be discovered by the An Yin Bureau's counter-reconnaissance, which was very risky.
This was not an unfounded guess. During Dorothy's occasional peeks at Grego, she had sometimes seen the An Yin Bureau's material allocation reports, which clearly recorded that the An Yin Bureau would purchase a certain amount of "Light" Spirituality storage from the Hui Guang Church at regular intervals. The stated purpose of the purchase clearly indicated it was for internal counter-reconnaissance, so Dorothy speculated that there might be surveillance cameras or something powered by "Light" Spirituality inside the An Yin Bureau that could detect abnormal supernatural intrusions.
Although Dorothy had the Concealment Ring, the Spirituality of "Shadow" was not particularly abundant. Heaven knows how strong the "Light" detection inside the An Yin Bureau is. Finding a mole is a long-term reconnaissance job, and Dorothy suspected that her little bit of "Shadow" wouldn't be enough. Furthermore, it was a bit troublesome for Dorothy to use the Concealment Ring with a Corpse Puppet.
For all these reasons, the cautious Dorothy did not directly send Corpse Puppets into the An Yin Bureau to investigate, but instead adopted a relatively safe but time-consuming method.
Holding the blueprints in her hands, Dorothy slowly looked at the locations she had circled one by one. These circled areas were doors or stairs, which Dorothy had marked as "entrances/exits."
"Spanning one street block, three buildings, nine entrances and exits... Heh... it seems the Igwinte Secret Agency's location confidentiality measures are somewhat effective."
Looking at the points circled on the blueprint, Dorothy slowly said. Based on her carpet-like investigation over the past few days, she had discovered the specific structure of the Igwinte An Yin Branch.
The branch headquarters is located in the basement of the Cypress Fir Building. The entrances and exits are disguised as ordinary doors, scattered within three adjacent buildings, including the Cypress Fir Building, all on the first floor. When the doors are opened, there are stairs leading down. The An Yin Bureau employees pretend to be ordinary people working nearby and commute daily through these ten or so hidden entrances and exits.
Locating these entrances and exits is not difficult. Dorothy only needs to use Corpse Puppets to check every room behind every door in the surrounding streets. Those that clearly don't match the structure of a normal house or are obviously strange are highly suspicious.
For example, if there is a row of doors in a corridor, and when you enter the other doors, you find normal rooms, but behind one door there is either a staircase leading down or a corridor, then this violates standardized construction and is very problematic. Dorothy only needs to arrange her Corpse Puppets to lie on the ceiling of the corridor, and when people pass by and open the doors, she can seize the opportunity to see the situation behind the doors. Another method is to follow and observe the building's cleaners and see which rooms they never clean. Dorothy even had Corpse Puppets crawl into the building's ventilation system to check which fake rooms were not covered by the ventilation system at all. There are many such methods... Incidentally, after the Corpse Puppet Ring's control was enhanced due to the "enlightenment" Spirituality, Dorothy can now control the corpses of arthropods like spiders. Although she can't control insects yet, her reconnaissance ability has improved to a new level.
In short, after expending enough time and energy and using various methods, Dorothy found nine hidden entrances and exits of the An Yin Bureau. Then, she only needs to spend a few more days using the maximum number of Corpse Puppets to stake out these entrances and exits and record the incoming and outgoing personnel to clearly know who the members of the Igwinte Secret Agency are.
And the mole Dorothy is looking for is among them.
