Bound to a Tycoon System: I Was Forced to Become a King

After transmigrating to the modern beast world, the rabbit demon Yao Yao gets a Rich Tycoon System. Before she can even laugh like a rabbit, the System tells her not to get cocky and to read the requirements carefully.

What?

She has to spend money on designated targets and earn their favor to grow stronger.

Even worse, the only way to become a real billionaire is to keep spending money on other people.

If the people she spends money on pay her back or return any of it, she has to cover the amount herself.

So becoming a billionaire comes with strings attached?

Still, at least the Rich Tycoon System has a conscience: her spending targets don't have to be male.

And she can get cashback.

That, she can accept.

Huh?

How did I end up becoming a Beast World queen who can rival the King of Ten Thousand Beasts just by spending money?

How unbelievable!

The first step to becoming queen: start by spending money on the person who saved my life.

P.S. Don't fall in love with me, because I'm a tool rabbit with no feelings.
