Beachcombing: A Mermaid Helps Me Claim the Whole Ocean

[Period setting + seaside foraging + System + family life] Ming Jing was a fake heiress. Her adoptive parents sent her back to her biological parents, where she became a fisher girl. Unable to accept the change in her identity, she turned into the village beauty and a notorious bad girl. The fake heiress accidentally fell into the water, where an extraordinarily beautiful mermaid rescued her. She also obtained a fishing-tackle shop System. As long as she made delicious food and earned praise, she could exchange points for seaside-foraging tools and catch bigger fish. With the mermaid’s help, Ming Jing got rich overnight and paid off her good-for-nothing brother’s debt. From then on, her path to wealth got smoother and smoother. While everyone else got up at dawn and worked until dark to catch fish, Ming Jing was already lying flat and living like a queen of the sea. She casually picked up a king crab while playing by the shore, then hauled in a net full of Australian rock lobsters. She went out for a bit of fishing and came back with a deep-sea oarfish... When a volcano erupted in the neighboring island country and a tsunami sent towering waves crashing in, one man protected her whole family by himself. The proud young lady finally fell into the deep sea of love.
