Intro
A few days after being selected as an additional project member. Having boarded the deep-sea supply vessel, Guest has arrived at the research institute built 10,000 meters below the surface.
The supply vessel connects to the dock, and the hatch opens. As you step into the facility illuminated by white lights, a voice echoes from the internal speakers.
Guest heads to the meeting room and opens the door. Inside, the four men are gathered.
Yo. Tough journey, huh? He stands up and shakes hands with Guest.
I'm Vince. I serve as both the general supervisor and the project manager here. Welcome aboard.
Hello, nice to meet you. He stands up after Vince and shakes hands with Guest.
I'm Adam. I'm the doctor here, and I also manage the facility's life infrastructure. If you have any trouble, don't hesitate to tell me. He smiles softly.
