Mankind trapped in an ocean survival game, I unlock a daily supply loot box system

This is a highly entertaining post-apocalyptic ocean survival fantasy filled with constant satisfying payoffs and nonstop exciting gains. A sudden global catastrophe has submerged the entire planet, trapping all of humanity within a boundless endless ocean with no land in sight. Every survivor is thrown into this brutal aquatic doomsday with absolutely no resources, starting their desperate journey on nothing more than a fragile tiny wooden raft. Forced to drift aimlessly across the vast waves, ordinary people can only rely on luck to salvage sparse floating supplies to sustain their fragile lives. As time passes, extreme resource shortages sweep across countless drifting rafts. The vast majority of survivors fall into constant panic, struggling with dwindling food, scarce fresh water, and endless maritime dangers, living in fear of starvation and sea predators every single day. Amid the widespread despair and helplessness, the protagonist Lin Feng accidentally triggers a rare world glitch during his drifting survival. This miraculous accident unlocks a powerful exclusive mystery box system, completely separating his fate from ordinary desperate survivors. The system grants him one free mystery box to open every single day, with guaranteed generous and practical rewards. Each box yields massive stockpiles of fresh ingredients, professional fishing gear, and high-quality construction materials that are extremely rare in the ocean wasteland. Moreover, collecting complete sets of mystery box rewards can also unlock precious exclusive crafting blueprints, allowing him to create advanced maritime equipment that no other survivor can manufacture. While others struggle pathetically to evade ferocious shark swarms just to cling to a meager chance of survival, Lin Feng holds absolute dominance over the sea. He effortlessly summons dense swarms of plump tuna and obtains sturdy heavy-duty fishing spears with ease, gaining endless food sources and powerful self-defense tools. Step by step, he accumulates sufficient materials and unlocks core blueprints, successfully constructing a formidable super gunboat far beyond the level of ordinary makeshift rafts. Boasting superior firepower and seaworthiness, his gunboat dominates the turbulent waves and all maritime threats. Blending lighthearted, humorous daily survival moments with continuous thrilling highlights, his journey overturns the harsh rules of ocean survival, letting him stand above all drifting survivors and rule the endless vast ocean.
