Pat pat...
Feil reached out a paw and tapped the crystal.
"A Spinosaurus egg fossil? It's clearly just a Black Crystal."
Feil checked the time. It was 10:32.
"Forget it, time to sleep." It yawned and took one last glance at the Black Crystal. Then, with a leap, it jumped down from the desk, shook its paws, and burrowed into Lin You's blanket. Half-asleep and in a daze, Lin You stretched out a hand and pressed the light switch.
With a click, the room was suddenly plunged into darkness.
Both human and cat fell deeply into slumberland.
But neither of them saw the Black Crystal on the desk slowly begin to emit pulses of purple light, like a heartbeat, flickering on and off. It resembled the power light on a mobile phone. A mysterious vibration slowly enveloped the room.
The next morning
