The System Gave Me Immortality and Asked Me to Become an Empress

[Protagonist pseudo-system + single female protagonist + empress development + saving the world + blackening + villain destroying the world] The world only knows that the empress loves a lot, but they don't know that she only loves someone so deeply that she loves the people she loves even more. But slowly Lin Shengge discovered that Long Yeye was the source of the destruction of the world, and she had a wish for equality for all living beings. Love yourself while attacking others... Always thinking about restarting the world. When he was seriously injured and slept in the river of time for a thousand years, when he met her again, she was already the world-destroying female devil... "Yeye, long time no see!" "What is in front of you now is a big demon who kills people without blinking an eye. Are you afraid?" "Then kill me!" When Long Yeye's sword pierced Lin Shengge's chest, his bright red blood stained her hand. Lin Shengge is dead! Standing in the long river of time, watching her regretfully turn to blackness and destroy the world. "Lin Shengge, even if the years are turned upside down, I will still find you again!" Long Yeye finally found him, destroyed the villain system with his own hands in front of him, and handed Lin Shengge a soul-eating sword. "Lin Shengge, I don't want to be a villain anymore, please kill me this time!" But seeing the Soul-Eating Sword she handed over penetrate his chest, Lin Shengge was puzzled. And Long Yeye laughed proudly: "Let's see if you die this time!" Only then did Lin Shengge realize that his nose was red! It turns out that she regretted not killing herself completely before! She can kill the person she loves most for her ideal... "Lin Shengge, only when you die can all things be equal." Absolutely amazing! The empress I trained is obviously the savior of the world! Why is he a world-destroying villain? What does it mean to just cry after killing? What else do you want to do if you keep the body intact?
