MTL - Dear Mr. Lu - Chapter 51

The alien DNA is the best thing that has ever happened to Ye Shuang because the genetic optimization it offers has made her more beautiful, more formidable, and more brilliant.

But… why doesn’t this unknown alien species have a fixed s*x before adulthood‽ Alternating between both sexes every few days, why‽ For gender equality‽ Thankfully, she still has a chance to save herself. As long as she can settle down with a partner before full genetic assimilation, she’ll be able to carry on with her life as just one specific sex. For the sake of the perfect female body, all the men out there, beware!

But wait, what are all these women up to? Why are you all looking at me like a piece of meat‽ Halt, stop, don’t come any closer… What the hell‽

- Description from Novelupdates

Crossing to One Piece world, he became Roger’s younger brother.

The story starts on earth, after some unknown circumstances, the world was suddenly invaded by monsters from other worlds. Many died and even more turned into zombies, starting what many would call 'The apocalypse Era'.

Rin, a normal teenage boy who lost all of his family members was on the verge of falling into despair when a goddess appeared and sent him to another world that was very similar to a game Rin played before the apocalypse.

Her goal from this was simple, trample on all the protagonists and become the strongest creature in that world for a chance to get back what he thought he lost forever.

Accompanied by a cold beauty, both of them embark on a new journey to become stronger, get back to their world and fix everything.

Min's system, System #151044, is tired of watching him get girls and make dumb decisions yet still manage to defeat the villain. If only he was the villain, there's no way Min would win.

His wish was granted. He now upgraded from a bodyless helper system to the evil villain, Ronin Dreadborne!

-----------------------------

After getting murdered and reincarnating as a system inside a Hero Transmigrating Machine, System #151044 spent thousands of years wondering why he had such a cruel fate to be a system for incompetent transmigrators like this.

But the worst is Min Cheng............

Because Min Cheng spends all his Hero points on girls instead of leveling up! And he is the dumbest transmigrators he ever met!

But through a rogue system that gave them a code to free themselves from their roles as a system, System #151044 was able to transform into Min Cheng's enemy on the next world, Ronin Dreadborne, in a mage fantasy world!

[Fate itself is evil. The only true enemy is fate, and I have defeated it.]

[And I shall teach you how to defeat it too. I will be giving you the gift of freedom. ]

[Be the master of your fate like you were always meant to be. And conquer those who try to stand in your way.]

That is exactly what he did as Ronin, and to defeat an evil fate, you have to be evil yourself!

“I will be the best villain in all the dimensions! Watch out, Min Cheng! I'm coming for you!”
