Rainstorm for Thousands of Years, My Doomsday Shelter

A heavy rain that lasted for thousands of years flooded the entire civilization, leaving the world in 3025 with only ruins floating in the endless ocean. Lu Chen woke up from hunger and found himself reborn back to the day he was betrayed by the goddess. "Su Yuqing, I want you to watch in this life - who is the king in the end!" Awakening the doomsday survival system, Lu Chen looked at the virtual interface and sneered. In his previous life, he was soft-hearted and gave the last piece of compressed biscuit to the school beauty, but she pushed him off the ruins with his own hands. Now that the system is in hand, every drop of rain is his weapon! While others were munching on carrion on the leaky raft, his shelter was lit with solar lights; while the survivors were fighting for half a bottle of fresh water, his water purification device was producing a steady stream of clear springs. The rich second generation who once looked down on him knelt on the bow of the boat and begged. The former goddess took off her clothes and just asked for a mouthful of food. "Want to come in?" Lu Chen looked at the embarrassed Su Yuqing and her new boyfriend on the surveillance camera, "First, spit out the supplies you stole from me!" In the heavy rain, a steel fortress is rising. And that fool who once starved to death is now the "Emperor of Doom" in the mouths of all survivors!
