Lin Wanwan, a doctor of marine biology, opened her eyes and transformed into a skinny seventeen-year-old child on an island in the 1970s. The family has only four walls, the roof is leaking, and underneath there is a sick brother who doesn't have enough to eat all year round, and a young sister who is crying for food. In the front, there are strange relatives who are eyeing him, and in the back, there is the village elder woman who makes irresponsible remarks. It's the beginning of hell! Fortunately, the [Ocean Encyclopedia System] was activated and came with a cubic meter of fresh-keeping space. While others were digging for clams, she followed the system prompts and fished out the best lobster from the cracks in the rocks. Others cast nets to catch small fish, but she followed the tide and caught all the rare large yellow croakers in her net. Sea cucumbers, abalone, grouper... In the eyes of others are unattainable rare things, but to her they are just "cabbage" on the seaside. When everyone thought that the Lin family was about to collapse, Lin Wanwan relied on the sea to raise her sick siblings until they were fat and healthy, and built the leaky thatched house into the most eye-catching blue brick house in the village. But, what happened to that cold-faced man who always "encountered" her at the beach? At first, he just silently handed over a tortilla. Later, he began to help carry heavy catches. Later, he gave her all the tickets he had saved: "What's mine is yours." Lin Wanwan: Thank you for the invitation. I just want to go to sea to support my family, not a man. A certain sinister boss (silently showing off his biceps): I'm strong, I can fish, I can repair houses, and I hand over all my wages. It's very cost-effective to support me.
