In a world where Spirit Summoners bond with legendary heroes to save civilization, I awakened as F-Rank—the absolute weakest. While my classmates summoned knights, saints, and mythic champions, my summoning glitched. The circle turned red, and when the smoke cleared, I was staring at the Tyrant Empress—a Calamity-tier villainess who nearly destroyed the world 800 years ago. Everyone calls me cursed. Dangerous. A threat that should be eliminated. They're right to be afraid. Because the Tyrant Empress wasn't the only one who answered my call. And unlike the others, my strength is forged in pleasure. Through forbidden dual cultivation with my villainesses, I grow without end. My name is Cade Marlowe, and I don't summon heroes. I only summon villainesses.

Wei Shi Lan is a cultivator who began chasing immortality so he would never die again. He discovered a unique method of achieving immortality, which was by cultivating the divine yin Qi of ten thousand goddesses, i.e., dual cultivation. He then began to work toward this goal. However, after cultivating one thousand goddesses and reaching the first milestone of his goal, Wei Shi Lan was betrayed by the one goddess he trusted the most. He died and reincarnated into the mortal realm ten years after his death. Fortunately for him, he reincarnated with the reward of cultivating the divine yin Qi of one thousand goddesses, The Primordial Dark Sea. Now, Shi Lan must start from the beginning. Armed with the sea that once served as the womb of creation, the origin of darkness, he will grow again and continue his pursuit of immortality.
