Mai Dong rushed into the core module and picked up the earpiece.

Her heart beat furiously as her hands trembled nervously. She was afraid that the sound she had just heard was a result of the computer's tiny bug, and that there wasn't any radio signal… The girl wore the earpiece, held her breath, and listened carefully.

A few seconds later, another beep was heard. The waveform on the screen jumped as Mai Dong's heart immediately tightened.

The computer wasn't having problems. There was indeed a radio wave, and it was a regular one. The space station had received an unknown signal that resembled Morse code. It blinked once every few seconds, and the oscilloscope resembled the electrocardiogram of a person.

Mai Dong was ecstatic. It clearly wasn't noise, but an electromagnetic signal with meaning.
