These kidnappers are very professional, having arranged everything so meticulously. They wanted her to change cars halfway and discard her phone, all to prevent anyone from finding and aiding her.
The alarm clock was set to remind her to check the note at the designated time.
Ou Lan immediately picked up the note and saw a few glowing words, "Drive east for ten miles, inside the abandoned factory."
The words disappeared quickly as they were exposed to air.
Evidently, the words on the note had been treated with special chemicals, leaving no trace once they vanished.
Ou Lan had no other option but to follow the kidnappers' instructions. She got back on the motorcycle and sped eastward.
After traveling about ten miles, she finally saw lights coming from the wilderness, which were from an abandoned factory at the foot of a mountain.
Ou Lan headed towards the factory.
