Lin Haisheng was reborn back to 2000; the tragedy of his mother being forced into debt by his eldest uncle and himself being sent to prison in his past life is still before his eyes. His eldest uncle uses a 50,000 yuan IOU to force him to hand over the house in three days, but he activates the tidal blind box system at Heishitan, unboxes premium seafood such as wild large yellow croaker and ornate rock lobster, sells them to restaurants to make tens of thousands in wild profit, and makes his wicked relatives stomp in anger—in this lifetime, he relies on the ocean to defy the heavens and change his fate.
