This secret code, Qin Chuan definitely doesn't know.
But it doesn't matter.
He was still ready to give it a try.
If he guessed wrong, he'd just take down this group directly and torture them thoroughly. After all, these people were no match for him.
Give it a try!!
So, he thought about a relevant couplet from his past life and finally said calmly, "The perpetual shall prevail."
Whoa!
The air seemed to quiet down for a moment, and the black-clad young man who had brushed past Qin Chuan stopped in his tracks.
He turned around solemnly and said in a low voice:
"Are you Nightingale?"
Qin Chuan was taken aback, then guessed that it was probably someone's code name. After all, spies loved using code names.
So, he nodded and said, "Mm."
"Come with me."
The black-clad young man said quietly and then walked toward a hill, while the dozen or so fellow companions silently changed formation and started closing in on the two of them.
