Abyss Gaze: My Prompt Entries Can Be Upgraded

When the "sea tilt" era came, super floods swallowed up the entire civilization, and the earth turned into an endless dark ocean. The embers of human civilization are scattered on the scattered building wreckage above the water, as well as... Rafts drifting with the current. When Chen Hang woke up, he found himself lying on a creaking old raft with only a worn-out [plastic hook] in his hand. Fresh water resources are running out, food is scarce, and beneath the water, twisted and evolved deep-sea behemoths are eyeing all the creatures on the raft. Bite! Deep Blue Survival System has been activated! [Successfully hooked "plastic fragments", wood +1] [Successfully analyzed the "mutant fish gene", radiation resistance +10%] [Successfully built "Seawater Purifier", survival points +50! While others are still fighting over a piece of moldy bread, Chen Hang's raft has expanded into a mobile fortress. While other fleets were afraid of storms and giant sharks, he had already set up his speargun and began actively hunting deep-sea aberrations. He thought it was just a difficult survival game until he used sonar to detect the huge shadow of the old civilization sleeping under the 10,000-meter trench, as well as the intermittent distress signals... "It turns out that floods are not natural disasters, but sifting." "Is the end of the ocean a lost Eden or an abyss where gods are imprisoned?" Starting from a raft, we build mankind's last deep-sea ark and explore the ultimate truth about the coming doomsday.
