An era where the desperate, miserable, and tragic tale of the six heroes who sealed the Dark Mage, who sought to destroy Maple World, became the favorite legend of children.

“The Cygnus Knights have fallen, the Resistance has collapsed, the Cross Hunters have been destroyed, and the adventurers have been annihilated. And the six heroes are dead.”

An era where no one dared to resist the reappearance of the Dark Mage and his followers.

“You are the only one left, El Paume. You’re the last adventurer.”

In that era, there was an adventurer who continued to fight until the end.

At the beginning of his rebirth, Mr. Zhou’s initial wish was to be a charterer who collected annual rent every day, 365 days a year.

Unfortunately, at some point, his life lost its leisure.

Invisible wealth, from millionaires to billionaires, step by step beyond the names on the Forbes rich list.

Once upon a time, just flicking it, it was midsummer.
