The coffin is the source of the soul nourishment effect on the Underworld Train.
Leonard Churchill had been curious about what exactly it was before this.
Besides, the unknown always makes one suspect that there may be some uncertain risks.
At present, he felt that, apart from the passenger in compartment 007, the mysterious coffin was something that had to be treated with caution.
Sophia Jones listened and retorted with a question, "Coffin?"
"Yes. Right in the compartment in front of the first-class, there's a black coffin..."
Leonard Churchill reiterated what he had seen earlier.
Sophia Jones paused briefly, as if trying hard to recall something, then raised her eyes to Leonard Churchill and shook her head, "I don't know. The notes contain a lot, but I didn't see anything about a 'coffin' when I read them before."
"Oh."
Leonard Churchill heard this and didn't ask any further, as the notes could be reviewed slowly.
