Bad news: Lin Shuwen is naturally prone to attracting ghosts. He could run into one anywhere.
Good news: Lin Shuwen is rich.
As the saying goes, money makes the world go round. It can even make ghosts push a millstone.
Lin Shuwen has no unusual powers and doesn't know any exorcism or warding spells. When he encounters monsters and ghosts, the only thing he can do is throw money at them.
What? Your lingering wish is to eat and drink your fill?
Fine. I'll have people burn money and incense at your grave every day, so you can eat to your heart's content!
What? Your only lingering wish is to make sure your wife and daughter will be all right after you're gone?
Fine. I'll take care of your family. I'll have her start working at my company tomorrow, with a monthly salary of ten thousand!
So, who still has a dream?
Over time, Lin Shuwen's company ends up with a whole bunch of monsters and ghosts on its payroll: a fox demon with a thousand years of cultivation, an ancestor-level vampire who's the only one of his kind unafraid of the sun... Wherever he goes, he can command a procession of a hundred ghosts if he wants.
One day, a veteran Celestial Master visits Lin Shuwen. “Young man, I see you've brought more than a hundred ghosts under your control. You must have some exceptional ability. Tell me, what is it?”
Lin Shuwen smiles faintly. “My ability is that I'm rich.”
