But judging by the dust on the keypad, most people used facial recognition.
Lin Jingjing felt a surge of anxiety. 'Don't tell me they all just used facial recognition for convenience and never touched the keypad.'

Since it had been used, her job was much easier. Lin Jingjing identified the digits that had been pressed and began her calculations.
All in all, it took her fifteen minutes to figure out the password.
When they heard a soft CLICK, the way the other three looked at Lin Jingjing changed completely.
Their gazes filled with even more admiration.
"Sister Lin, how did you know?" Shi Feng asked, stepping forward with a fawning expression.
