I Routenely Get A Treasure

Rain's Goldfinger allows him to pick up a random treasure every day.

On the first day, he got a high-level meditation technique.

On the second, day she got a marvelous potion.

On the third day, he got a powerful magic item.

On the fourth day...

On the fifth day...

After a thousand years, Rain glanced at his inventory, which was completely full. He grumbled, "System, my inventory is full. Can you stop forcing me to take more treasures!"
