There's something almost poetic about Si Wang's plans being thwarted by the cruel unpredictability of war.
In any case, Yao Shen could see how he used memory as his weapon to try and wrest control of Yao Shen, until this current incarnation.
Until Yao Shen almost gave him his victory -- but in the end became his downfall.
He wipes the tears off his face and gets up to his feet, finally opening the bedroom door.
He finds Xin Hulei smoking by the open windows, a cigarette clutched tightly between his index and middle finger.
Yao Shen regrets worrying him, but he doesn't regret what he has found.
He has the solution to one last mystery on the tip of his fingers -- at least a partial solution, there's some of it he still doesn't understand.
"How are you?" Xin Hulei asks, his tone more casual than he feels.
"I'm fine." He nods towards the cigarette between his fingers. "Finish that, there's somewhere we need to go."
