Raft for All: I'm guaranteed to get a golden affix when I upgrade!

Humanity from all over the world has been transported to a world of survival on a raft. One person, one raft, one white shark. No food, no water. Only a grappling hook. Lin Chen thought he was doomed, but unexpectedly activated the [Affix System]. By leveling up, he could choose concept-level affixes and bestow them upon any item! Reaching level 1, he obtained the affix [100% Accuracy]! He bestowed it upon a tattered plastic hook, and with one cast, he could blindly snipe a golden treasure chest a hundred meters away! Reaching level 2, he obtained the affix [Endless Spring]! He bestowed it upon an old water cup, and from then on, he could drink unlimited amounts of sweet mineral water; while others drank urine, he could bathe in it! Reaching level 10, he obtained the affix [Fear of Insufficient Firepower]! He bestowed it upon the raft with a repeating crossbow, firing a thousand explosive arrows per second, blasting deep-sea monsters to smithereens! ...While other survivors were still arguing over a piece of moldy bread, Lin Chen's raft had already transformed into a floating city covering tens of thousands of acres, equipped with planet-destroying cannons. Lin Chen: "Can anyone tell me how come this underwater god can't even withstand a single shot from me?"
