"Killing people like they're nothing?"
Nan Yu caught the most critical phrase and narrowed her eyes involuntarily.
X and Z nodded simultaneously, both revealing a distaste for Shen Lu in their eyes.
X stuttered as he began, "Boss, at first, the S... wasn't Shen Lu, she was the one who came after..."
Before he could finish, Z took over. "My brother is too slow, let me explain," he said to Nan Yu.
"Shen Lu joined us when she was twelve years old. By then, there was no place for her in the Dark Night Organization. If she wanted to stay, someone had to leave."
A light flickered in Nan Yu's head, and she blurted out, "Don't tell me she killed S to replace her?"
Z nodded gravely, "Exactly, because her surname is Shen, and she wanted the 'S' codename, she killed the original S."
"Since then, she joined the Dark Night Organization, and would eliminate anyone who posed a threat to her interests without hesitation."
