The past is submerged and civilization sinks. The earth turned into a filthy ocean, and survivors struggled to survive on the rusting wreckage.
On a broken ship that was about to sink, Li Mo killed someone for a mouthful of fresh water, and accidentally inherited a strange scale from the deep sea.
"Qualified candidates detected, the deep sea evolution system is bound..."
The power arrives like a loan, but the price is unknown.
Mutated monsters, scarce supplies, competing survivors... And the indescribable ancient whispers hidden under the filthy sea water are tempting and corroding all the time.
If you want to survive, you must continue to "borrow" power, and every time you repay, you may pay for your reason and humanity.
In this cursed ocean, can Li Mo find a way to survive before going completely crazy or deformed?
Or will he eventually sink into the abyss and become part of the eternal nightmare?
