[Crossover] The Road to Becoming the Richest

I entered a new world again, and the System's mission for me was to become the richest person in the world.

But the only two cheats I have right now are a pair of unusual eyes and the bloodline of Tomie.

I know perfectly well that my business skills aren't enough to build a vast commercial empire. I also don't have the patience to spend decades or centuries accumulating wealth, so...

The quickest way to complete this mission is obviously to find the world's richest person, marry him, then kill him and split the inheritance.

Before long, I found my first sucker, the owner of a well-known pharmaceutical group with a chain of hospitals. But on the third day of our marriage, he brought home an adopted son.

Looking at the polite little boy and listening to him call me Mother, I couldn't help wondering how much I could get for selling Muzan Kibutsuji to the Ubuyashiki family.
