At the same time, amidst a secluded alley, came the sound of rustling. A few men dressed in black strolled with caution, carefully making their way into a dilapidated old building.
With the aid of moonlight, they placed their hands on a tile on the wall, gently pressing down, causing the tile to sink in. Beside them, a door slowly opened, emitting a faint yellow light.
The men in black exchanged glances and nodded, bending over as they walked inside.
After walking scarcely a hundred meters, the rising sound of chatter grew closer. They shed their black clothing, revealing bright and elegant suits.
They soon approached the source of the noise, pushing open a heavy iron door.
"I bet big, big..."
"Come, come, another round..."
This is a gambling-centered underground bank, hidden with extreme secrecy, known only to a few business moguls and gambling enthusiasts.
