A strange undercurrent on the sea floor plunges Wen Wan, who is deeply involved in marine research, into the primitive and barbaric ancient times.
After waking up, his legs completely turned into a glazed mermaid tail that gradually turned light blue, drifting in the dangerous ancient offshore sea.
Violent deep-sea behemoths are everywhere, land orc tribes waiting for opportunities to hunt mermaids, dangerous undercurrents and miasma waters, the weak little mermaid is struggling.
By chance, she was taken in by Lan Shuo, the lord of Cangjiao who lived alone in the deep sea.
Relying on the complete modern ocean knowledge in her mind, she can identify toxic algae, delineate safe habitat areas, avoid seasonal tide disasters, domesticate docile small water animals, and gradually transform the depressing and desolate underwater life.
The overlord Cangjiao, who was originally unkind, was willing to guard an area of the sea to isolate all dangers, and allowed this little mermaid to break into the lonely deep sea to create unique and gentle waves on the seabed that had been cold for thousands of years.
Intention: Survive in adversity and never give up
