Pulane felt extremely uncomfortable as Jacob asked all kinds of strange questions, both personal and meaningless. Yet, he had no choice but to answer since Jacob wasn't someone to take a no.
Pulane led Jacob towards the estate treasury, where all the accumulation of the estate and treasures after an estate lord anointed were gathered. No one could take anything except the estate lord. The servants were to deliver anything to the Dark Rose in the absence of the estate lord, and then the Dark Rose would lock them into this treasury.
Only when they reached the estate treasury did Jacob stop questioning Pulane, and the poor butler sighed with relief.
Jacob used his star watch against the secret mechanism on the locked dark door. Once his ID was confirmed, the cogwheels began to rumble, and soon, the dark door opened.
