Modifying Myself into the Ultimate Demon

I'm called Chen Mo, I transmigrated.

Good news: I'm a rich young master, clad in fine silk and eating delicacies, surrounded by beautiful maidens.

Bad news: Hit with a ghost curse, might turn into a ghost at any time.

The maidens are still here, but it won't let me stay human?

[Parser: This isn't an ordinary ghost curse, it's a ghost fetus]

"Ghost fetus? So when it grows up, will it burst out of my body?"

[Yes! Modify bloodline to fuse with ghost fetus?]

"I have a choice? Modify!"

This is a world rampant with demons and monsters.

Ancient mansions with red lanterns, paper effigies singing ghostly operas, white nooses of hanged ghosts, dilapidated temples enshrining evil immortals.

I just want to quietly be a rich young master, but... there are always demons trying to harm me.

So I have to keep modifying myself, fusing with myriad ghosts and demons... until one day, all demons and ghosts fear me.

Because, I have become the ultimate demon!
