Occasionally, the researchers would feel a glimpse of peeping through the gap, but when they explored carefully, it disappeared quickly, like an illusion.

Several researchers were walking in the corridor, one of them stopped suddenly, he raised his head, and subconsciously looked at the top of his head, the ceiling partitions were still tight, he and his colleagues looked at each other, once again attributed thisHallucinations caused by stress.

After they left, a large group on the ceiling became active again, controlled itself not to make a sound, and slowly moved towards the third area.

Out of the sight of the researchers, all the experimental subjects that could come up gathered on the ceiling partition of the third area.

During this time, they have explored all the areas of the ceiling compartment. Although there is still a "wall" around the end, they can reach any place in the laboratory through the ceiling.

Some seemingly useless skills learned from "Mom" come in handy at this time.

Their excellent memory allows them to clearly remember the route and general direction they have passed. The juice of colored fruits is used as ink to draw a map of the area on the white partition.

"We are here." Number 77 first used red juice to draw the approximate shape of the third district.

"This is the corridor..." He centered on the third district, and the "map" began to extend around, "This is the corridor, the incubation area..."

77 slowly replenishes the areas that he and 76 passed through.

After drawing a part of what he had been to, 77 moved back a little, giving the position to the next experimental subject.

Storage room, cold storage, utility room...

During this period of time, the footprints of the experimental subjects covered almost all areas in the laboratory. They would occasionally open a gap in the ceiling partition that opened the blind spot for monitoring, and through this small gap, observe the people coming and going.Busy researchers.

After the addition of the experimental subjects, a few days later, the rough floor plan of the laboratory quickly took shape.

77 looked down at the map that was almost completed, patted his tail lightly on the floor, and said in a tone of unknowing eagerness, "How long do we have to wait?"

"Should be soon?" An experimental subject looked through the glass, looking at the closed gate of the third district, "I want to lock up 'Mom'."

"Where is it going to be locked up?" 77 turned to look at him and asked curiously.

The experimental subject thought about it seriously: "It's right here."

His tone was firm: "'Mom' likes this place."

After the lights were turned off at night, 77 climbed up to the ceiling shelf and gently lowered the shelf.

He crawled forward with his head down, and the tail that dragged behind him ran into some obstacles from time to time. He had to admit that at this time, the legs that 77 didn't like very much were indeed much more convenient than the tail.

77 hesitated for a moment, and quickly transformed his tail into human legs. 77 continued to bow his body forward. He had already checked the location of the isolation room very clearly, and he chose the forward route without much hesitation.

The sound on the ceiling can be hidden from human ears, but 76 cannot be avoided.

76, who was staying in the isolation room, opened his eyes when he heard the movement above his head.

When the sound approaching him stopped, 76's tail tapped lightly on the glass, and he knew that 77 could hear it.

Then 77 heard a voice from below: "Good evening, 77."

77 followed the direction the sound came from, and finally stopped on a partition. The number of monitoring equipment in the isolation room far exceeds that of other places.

77 resisted the idea of wanting to see 76, and his legs returned to the state of tail after he stopped.

He tapped his tail on the partition as well, as if in some kind of response: "Good evening, 76."

"I haven't seen you for days," he said.

"I miss you very much."
