In a world where KPIs are the value, life, old age, illness and death can all be quantified. Lin An spent everything just to find the truth about the drowning of his sister Lin Li. She disappeared mysteriously in a mysterious incident, and the blood taboo of "not going to the sea" and the cold system discipline of her family for generations were washed away in the tide of despair.
He resolutely set foot on the deep sea that once made his blood tingle, but encountered an all-devouring fog during his first voyage. Along with his ship and era, he was involved in a forgotten time...
The thick fog cleared, and Lin An and the broken ship fell into a forgotten time. Here, the pointer to quantify life is no longer effective, only the turbulence of time and space and the ancient horror of deep dive. Carrying the curse that caused the disaster, he must find an answer that may not exist for the people he loves and the world in this frozen graveyard of time as he gradually slides into the inhuman abyss. Then he will get the truth and freedom he wants.
