The meeting with Miss F went smoother than Zhang Heng could've imagined.
The fact that Miss F was Tang was actually Zhang Heng's wild guess. After all, everyone knew that Tang was dead. The police found her body and chips after she set herself on fire. Tang was also a celebrity clone built by an entertainment company with a lot of money. She was supposed to have the perfect facial features. On the other hand, although F wasn't unsightly, she could only be considered ordinary-looking. She wouldn't be grabbing anyone's attention when she walked on the street.
The only thing that could connect F and Tang were their mechanical prosthesis. According to the rumors circulating on the internet, Tang lost an arm when she escaped from the fifth level. Other than that, the reason why Zhang Heng thought F was Tang was her temperament.
