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.
