Noa’s life turned into a disaster.He was fired for no reason, betrayed by the woman he loved, and left drowning in debt for a wedding that would never happen.Then a truck almost killed him.And just before the world went black—time froze.Suddenly, Noa is no longer an average human—he is a Dimensional Tycoon, capable of buying and selling planets at market price.When gods need immortality, Noa sells them elixirs. When demon kings want weapons of mass destruction, they pay in cash. When heavens fall, he buys the land. When empires collapse, he auctions the ashes.Noa can trade anything, as long as the price is fair.He doesn’t conquer realms, because in this world, money is the greatest power—and Noa controls the market.After all, even divine beings knock on his door—not to fight, but to ask for a discount.But every tycoon has to start somewhere.For Noa, it began with selling shampoo to bald cultivators.
