Benghuai: Xingqiong Tiedao - Fei Ling He Boyi

"Your humble servant 'Aventurine,' at your service. Just a cog in the machine known as the IPC's Strategic Investment Department. Nevertheless, I can also play the role of "friend" — if needed."
"Go ahead, use me as you wish, even stab me in the back when you see fit. But remember, I don't make deals that don't pay off... So, I hope you don't disappoint me."
