After resigning, Lin Xia inherited the dilapidated seaside aquarium left by her grandfather. The venue was desolate and abandoned, with only a pink dolphin named Pipi standing out, claiming to come from the legendary Atlantis. While chasing Pipi, Lin Xia accidentally fell into the pool and discovered a secret door at the bottom of the water tank leading to the lost underwater ancient city. At that time, Atlantis was deep in a famine, and the sea-dwelling residents were struggling to make a living. Possessing an exceptional talent for cultivation, Lin Xia cultivated high-yielding crops, solving the food and clothing problem for the entire clan. The sea royal family rewarded her with a large number of deep-sea treasures, which Lin Xia used to renovate the venue, introducing rare marine life such as colorful eels and oarfish for exhibition, and the old aquarium became an overnight sensation.
