The final destination of this 'bus' is precisely the goal of Han Dong and his companions - [Dead City. Zurbaha].
However, this is not a direct route.
Along the way, it also stops at villages and small towns, and even detours through some regions, taking a big loop.
According to the ghoul driver embedded in the driver's seat, who hasn't moved for years, the entire journey takes at least a full day.
Before boarding.
Mr. Newton used a "self-modification" technique to fold his body, transforming it into a mechanical Rubik's cube.
When Han Dong first touched the Rubik's cube, he could not feel any life force, needing to sense deeply to faintly hear a heartbeat.
If one peers into the mechanical Rubik's cube with special vision.
One would find a [workspace] within the deepest part, opened up by the mythical field, where Mr. Newton is writing technical papers for subsequent negotiation talks.
"Let's board the bus."
