Due to his work, An Zhiyuan had gone missing many times before.
Whenever no one had any clue about his whereabouts, Bai Xiao would find it impossible to sleep.
She was not familiar with their system; she was not yet with him when he worked there and didn't pay attention to such details.
But she had once observed their training.
Though it was nothing more than a fleeting glance, she had already realized that both their endurance and their team's coordination had been rigorously tested, leaving only the very best.
An Zhiyuan, in particular, loved his job, but, after all, these people were only human.
They too could be killed, and the nature of their work meant they were always taking risks.
Their training accentuated a major part of An Zhiyuan's nature; he was honed into the likeness of a perfect fighting machine, at the peak of his capabilities, favoring intellect over brute force.
