Fang Cheng had already suspected that Nangong Saya was connected to Machine City.
But it wasn't until tonight that he finally confirmed she must have lived in Machine City.
While they were looking for Central Street No. 26 tonight, Nangong Saya had asked for directions a few times, but she had also let slip that she was familiar with the city's layout.
Then she had immediately identified Siye Hui.
How could someone who had lived in Tokyo all her life recognize Siye Hui at a glance?
Tokyo's government had long since suppressed all information about Machine City. Ordinary people couldn't get their hands on any of it, even if Nangong Saya had once been a member of the Countermeasure Department.
The Countermeasure Department had only basic information on Kozaki Wataru. There wasn't a single word about Siye and his father.
And earlier, when Fang Cheng said that no one who entered Machine City could leave, Nangong Saya had claimed she knew a way.
All of it suggested she had deep ties to Machine City.
Nangong Saya fell silent, her fists clenched as her heart pounded wildly and panic gripped her.
She had been so nervous that when Fang Cheng asked who Siye Hui was, she'd answered without thinking. Only now did she realize she'd let something slip.
Seeing her stay silent, Fang Cheng said in a low voice, "Looks like you don't consider me a friend. You're still keeping things from me, so let's end our friendship."
"Don't!"
Nangong Saya blurted it out before she could stop herself, grabbing his clothes.
From her reaction, Fang Cheng knew he had her.
Normally, he had no interest in other people's private business. But he'd taken all those shell hits to help her tonight, and she was still hiding the truth from him.
