I Became a Succubus at the End of the World and Roamed It with the System

Apocalyptic survival + transformation (male-to-female) + childbirth + one-on-one romance + play the pig to eat the tiger

It began with nothing more than a heavy rain. But by the time people realized something was wrong, the entire world had begun to change. All kinds of creatures started evolving, while those that failed to evolve became man-eating monsters.

Dou Si merges with the memories of her parallel-world self, who lived through the apocalypse. She also brings along the interface from the game she was playing, and becomes a succubus. When Dou Si sees how she can grow stronger, she has no choice but to latch on to the powerful figure from her memories.

At first, Dou Si really only wants to cling to someone powerful. After all, she’s become a succubus, and she can’t give up an entire forest for the sake of one tree. But who could have guessed that this tree would grow all the way to the heavens? Dou Si has no choice but to hold on tight and grow stronger.
