After Yan Yi and the others entered the teacher's office, the cabinet in the laboratory quietly opened, and Ning Xinyuan came out first, followed by Le Yuxin.
Le Yuxin didn't rush to leave but instead put the clutter in the cabinet back in its place, then picked up two strands of black-red hair from inside——this was a memory reminder from Yin Yinyin. After completing their assassinations, white-haired assassins would always collect any white hair they lost in order to conceal the truth of 'white-haired felons', making others believe the murder was committed by a hotel attendant/a passing Masked Rider/a bandit of the seas/a beautiful girl.
