She Was Pregnant with the Abyss Cub Without Telling the Leader.

Three years after the end of the world, yellow sand was everywhere, and Wen Nian was held in the palm of the hand by the leader of the base, Shen Yu. He is humanity's backer, cold and powerful, protecting her from the tide of corpses and giving her stability for the rest of her life. But she hides a secret that she dare not tell: after a drunken encounter, she became pregnant with the child of the most terrifying red-eyed zombie in the apocalypse. On one side is a human leader who shows all his tenderness, and on the other side is a bloodline of the abyss with forbidden evil fate. She struggles with lies and fear, fearing that her secret will be exposed and she will be doomed.
