The voice echoed inside Nikolai's mind, just once, before the deep rumble was overtaken by the hum of something hidden in the darkness. All that appeared in his gaze was the damaged tower, wrapped in a horizon of endless dark matter and twinkling stars.
Nikolai tried to rationalise the sound, as he did with anything.
The likelihood of hearing a voice echo inside a mind with no source would be just impossible, right? But Nikolai was having trouble thinking at all.
When his connection to the girls vanished, even his link to Sarah faded, he became isolated in this strange world.
『Complete the challenge to survive.』
Once again, the strange voice echoed, but this time in r-dialect, something that Nikolai understood well, causing him to stand up and dust himself off.
