Everyone Survives Under the Sea, My Submarine Evolves Infinitely

When I woke up, billions of people sank into the deep sea in a survival game. Each player starts with a submersible. While others were shivering in diving suits, glass boats, and broken iron cans, praying not to be targeted by mutant fish, Su Hai calmly sat in the cockpit of a military submarine. [Daily Information System] Binding. From this moment on, the deep sea had no secrets from him. While others were wandering around in the dark, he had a map. Others were ambushed by monsters, so he laid a trap in advance. While others were fighting to the death for a box of supplies, he was already on his way to sweep the next S-class ruins. [Engine] + [Nuclear Power Energy]... A deep-sea fortress that never shuts down. While others wait to die without power for three days, he cruises at full speed all year round. [Torpedo Tube] + [Infinite Copy]... Once a torpedo is fired, a new one will be automatically generated after a few seconds. The firepower of a single submarine is greater than that of a fleet. [Shell] + [Eternal Durability]... The mutated shark had a mouth full of teeth broken, and there wasn't even a white mark on the boat's hull. The behemoth of the abyss slapped its tentacles down, and the tentacles were broken. While other players are killing people for half a bottle of oxygen and having nervous breakdowns in the claustrophobia... Su Hai was lying on the leather sofa in the panoramic observation cabin, sipping freshly picked vegetables from the underwater ecological plantation, and looking out the window at the abyssal beast that was crazily hitting the submarine. He put down his chopsticks and said calmly: "Have you hit enough? It's my turn." Under the deep sea, he is a natural disaster. From [Lv.1 Rusted Submarine] to [Lv.100 Mechanical Scourge].
