Villain: Ultimate Mutation System in the Alternate World - Chapter 616: Advancement?

A mysterious natural phenomenon caused the Earth to be plunged into darkness. The world turned into an endless bloody chaos and mankind is on the brink of extinction…

I was betrayed in my first life.A cripple, broken and discarded—I died after catching the one I loved in bed with the only person I ever called a friend.That was the start of real torment.When I woke up, it was in another world.A goddess stood before me.She told me I could go back.Back to my world.Back to everything I lost.All I had to do… was play my part.The side character.And I did.I followed the script.Played my role to perfection.They hated me.Mocked me.Used me.Again and again.But I kept going. Because I believed her.Because I wanted to go home.Then one day, I found out.The hard way.It was all a lie.There was no going back.There never was.She used me.Again.Just like everyone else.Thrown away like trash once I outlived my usefulness.That was the day something inside me snapped.And so, I made a vow.I would take everything from her.I would enslave every single heroine she chose.And I would kill the hero she placed all her hopes on.If she wanted to protect this world…Then I would burn it down.But the more I tried, the more things started to change.And then one day—I found one of the heroines.One of the hero's yanderes I had enslaved.She stood there, trembling, a knife in her hand.“You’re not going anywhere,” she whispered, eyes wild.“I won’t let them have you. You belong to me.”...What. The. Fuck. Is. Happening?!

“The Earth was chosen by the gods, and all humans were sent to another world, participating in a 'Dark Lord and Hero's game'.Billions of humans played the roles of 'Dark Lord' and 'Hero', each needing to choose their initial race at the beginning.Ethan Jackson was matched to the 'Dark Lord' faction and became a Dungeon King.To his surprise, he found that he could see hidden information that others couldn't...[Goblin Dark Lord] Low-level Bloodline, not recommended.[Stone Giant Dark Lord] Mid-level Bloodline, not recommended.[Magical Treant Dark Lord] High-level Bloodline, recommended.[Golden Divine Dragon Dark Lord] Top-level Bloodline, highly recommended!...Heroes coveted Ethan's dungeon, and the treasures within it attracted numerous adventurers.Among them, there were young Lady Knights, the saints of the royal capital, tsundere female magicians, and innocent but naive female priests...Ethan could never have anticipated that.As the game had just begun, the dungeon's Goblin guards caught a Lady Knight and offered her to him as a tribute.”
