Dream Wilderness.
Cold metal lines, minimalist design, and white-robed figures moving through the rooms.
This was the Sin Demon Laboratory, far from Firstheart City.
Angel was currently in the Sin Demon Laboratory. He stood before a transparent floor-to-ceiling window as the rosy-red sunset streamed in, laying an orange-red carpet of light across the floor and making his features appear even more sculpted amid light and shadow.
This was the upper level of the Sin Demon Laboratory, and also the only office from which the outside world could be seen.
In Angel's view, an endless wilderness stretched beyond the window. Only to the south was there a dense layer of black mist, its darkness cleaving through the red sunset like the boundary between dusk and dawn.
That black mist was where the Sin Mist had manifested.
Angel quietly watched the black mist churn. After a long while, he softly said, "The Sin Mist's range seems to have spread outward a little?"
"Yes. The boundary markers you previously established have been pushed forward by roughly half a meter." Frod stood behind Angel and replied respectfully.
"Half a meter? Then for now, its rate of advance is still within a controllable range." Angel turned around. "Continue operating the scouting puppets and record the rate of advance at all times."
Frod nodded in acknowledgment.
Angel returned to the desk and accepted a report from Frod.
—"Heart House Experiment Record: Sabel"
The report was crammed full of writing, and it was rather messy. The ink was still fresh, making it clear that Frod had only just rushed it out.
After reading through the experimental process, Angel carefully examined the conclusion and sank into thought.
Angel said, "Judging by the report, once a Sin Demon enters the body, it does indeed appear in the Heart House."
