The Entrance to the Unknown Space

In the suburbs of Jinghai City, within the Smith family's villa, Donald slowly revealed the clues to the Smith family's hidden treasure to Elder Seville and Irving.

"You should remember the Benevolent Sanatorium where I used to stay, right? Although the Benevolent Sanatorium is officially a very upscale sanatorium, in reality, there is an entrance to an unknown space beneath it. This entrance was discovered by an ancestor of the Smith family. One of our ancestors ventured into this unknown space. Upon his return, he recorded in the family genealogy that there was hidden treasure in the unknown space. He also continuously tried to re-enter the unknown space. Unfortunately, his endeavors were unsuccessful. This ancestor passed away five years after discovering the entrance. Before his death, he endlessly recited the existence of the treasure within the unknown space to his family," Donald recounted.
