After traversing to the apocalypse, I am extremely delighted as a Demon Cultivator - Chapter 25 - The righteous destruction of relatives and the son of fire, the eternal magic green technique

Li Ke Lin (also Li Colin), a Chinese office worker, woke up to find himself suddenly no longer Li Ke Lin but instead Colin Lee, son of multi-billionaire in America. Having taken over the body of Colin Lee and carefully imitated his manners and bearings, his next goal is to inherit his father’s wealth. However, when his father lists the condition of marrying a woman who feels repulsed by Colin Lee’s (not Li Colin’s) dalliances, and whose very nature is the complete opposite of Colin Lee (not Li Colin), what must he do to gain her affection?!

Opening her eyes, she becomes the eldest daughter of the Great General of Liuyin Kingdom.She is the modern girl that transmigrated into a world that only respects the strong.Bullied by her cousins...Broken engagement...She did not care about all of that.Her motto is inspired by one of her favourite anime, Hyouka: “If I don't have to do it, I won't. If I have to do it, I'll make it quick.”“You already come into this Lord's hug. Don't you dare to run?” A Lord threatens her.“Do you think I'm scared of you? You can keep dreaming.” She spoke back.She just wants to have a peaceful life, however, can she has it?

Katherine Zara, a single middle aged office worker, went about her day as she always had; wake up, go to work, come home and read or play games. However, today would be different. Before she left for work, her ex broke into her apartment and killed her.

When she woke up, she was given many choices. She could pick her new world, pick her starting point, and pick her system among many other things. And so Katherine decided to become a servant to a villainess.

Follow Katherine as she serves her petty, demanding mistress in a world of swords and magic.

Additional: The Female Lead (Katherine) will be submissive to her mistress, but will be cold towards others. I plan on having some action, but mainly this will be a story about Katherine serving her mistress and leveling up her system.
