But right now, dwelling on such things is meaningless. Sun Hang switched to a backup subway card, swiped it, and slipped into the compartment of the ghost train.
Under Zuo Jun's "escort," the other members of the team also safely boarded the train—apart from the subway card Sun Hang initially used, none of the other cards had insufficient balance issues.
As the compartment doors closed, Mr. Wang immediately stood up from his seat and moved to the adjacent compartment.
She walked up to a standing passenger's virtual projection, examined it for a moment, then passed straight through the projection.
"Hey, that's interesting," Mr. Wang said with a smile. "Feels like a holographic projection. Maybe there's a lens hidden in this compartment to project images."
"Those people… are they ghosts?" Watching Mr. Wang playfully passing through the projections, Bai Lingqiu turned to Sun Hang and asked quietly.
"In a way, yes." Sun Hang nodded.
