Arthur is not a person who makes a fuss.
This was true back in his hometown.
Upon arriving in this world, he was further tempered by the profession of 'Spirit Medium,' developing an instinct to conceal his emotions.
However, when he saw the attributes of the "Thief's Door," Arthur could not suppress his surprise—
[Stealing: Consumes one's lifespan to steal the other's items, skills, experiences, existence. Both parties need to undergo a 'Spirituality' judgment. When one's 'Spirituality' exceeds the other's, the judgment passes, and the stealing is successful. If the judgment fails, the target will become alert]
[Transplant: The Thief's Door can be transplanted anywhere you deem suitable]
[Immortal: The Thief's Door possesses divinity, and the transplantee will gradually acquire a hint of the immortality within the divinity, thereby stimulating their bloodline]
