MTL - Diary of a Sturdy Immortal - Chapter 1308 look familiar

In a world heavily dependent on technology, humanity always strived for more. And when they transferred the human consciousness into a virtual world, everything changed.

People got different systems, some unlocked superpowers while others simply became stronger. There were all kinds of things people obtained, and they all came from an unknown world later named “System Online”.

A virtual world that allowed people to get stronger as they played in the world in a manner that altered their destiny, raised their strength, and gave them a chance to be what they never were.

Follow as the main character enters this world to change his destiny and help out his loved ones. However, never did he know that he would become someone at the center as the whole world faces doom.

Read how this world of System Online becomes the cause of the apocalypse on Earth a hundred years later while a new even more vast universe opens up to humanity while the world of System Online descended on Earth as both worlds merge in some unexpected circumstances.

This all leads opens to Universe where humanity's survival hangs at the stake.

A universe where humanity is at the bottom and countless races eye Earth for its resources and treasures.

A universe where the strong prey on the weak.

Tong Nian, a cosplay cover singer, falls in love at first sight with a man she spots at a Net cafe. Chasing him, she signs up for the MMO she saw him playing, albeit it’s a super high ranked account a friend acquired for her. Who could have known he was a pro gamer, moreover a legend in the gaming circle at that!

The world has changed into something like a game.

It resembles a survival virtual reality game where people were attacked by zombies and monsters.

And I was the last user of that game.

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.
