"Doomsday: Draw cards and build a city on the water at the beginning"
On July 7, 2037, the global sea level rose by 100 meters overnight. Cities sunk, continents disappeared, and billions of people were swallowed by black water. The survivors could only lie on the roof, holding the floating board, struggling to survive on the endless black ocean. The black water is poisonous, the black mist is deadly, and there are hundreds of meters of giant fish swimming underwater. But the end of the world also brings something - the "global card drawing system". Each person has one chance to draw a card every day. R-rated to SSS-rated, from a bottle of water to a city, it all depends on the face. Shen Yuan, an ordinary city planner, discovered something on the first day of the apocalypse - his probability of drawing cards was higher than everyone else. When others drew R-level mineral water, he drew an SSR-level floating island foundation. While others were fighting over a pack of instant noodles, he had already built the first water base using the building materials he had drawn. What's even more outrageous is that his mobile phone has an extra function that others don't have - "information analysis." He can see the truth behind the card drawing system: this is the seventh restart of the world. The first six times, all failed. And he is the "key person" selected this time. Start with a floating board and end up with a floating city. From thirty-nine survivors to the Alliance of Civilizations with one million people. From surviving on the water to gathering twelve ark fragments and sailing to the deep sea. What Shen Yuan wants to do is not just survive - he wants to lead all mankind to pass the ultimate test and end this apocalypse. "Card Drawing City Construction × Doomsday Survival × Power Struggle × Deep Sea Exploration" This is a story that starts from a floating board and eventually rebuilds an entire civilization.
