I Have a Safe City

Cheng Qisheng is an ordinary person suffering from a terminal illness. She got a miniature planet with nothing on it except a dilapidated city. The time flow of the miniature planet is many times faster than that of her world. Cheng Qisheng decided to cultivate human civilization on it and let the new humans find ways to cure their diseases. Good news: The new humans have a strong sense of loyalty to Cheng Qisheng and regard her as the God of Creation. Bad news: The new humans haven't been able to find a cure for her condition either. Even worse news is that the miniature planet is destroyed and Cheng Qisheng is going to die. Moments before the planet was destroyed, the dilapidated city suddenly sounded a prompt: "Successfully bound to the safe city!" ——Safe City, a city that will come to every world where disaster breaks out. The city lord can take at least 10,000 local residents and rely on the safe city to stay in various disaster worlds, collect resources, and continuously rebuild and upgrade the safe city. Either the safe city collapses and dies during the upgrade process, or the player upgrades all the way and eventually becomes a new world. When the safe city was upgraded, the city lord would also be upgraded. Cheng Qisheng was surprised to find that his terminal illness could be cured! The city lords have a group chat. City Lord No. 1: "The residents are too difficult to manage. They always want to rebel against me. What should I do?" City Lord No. 2: "The number of my residents is too small, what should I do if I can't get enough resources to upgrade!" City Lord No. 3: "There is a safe city that starts a war with me. What should I do if I can't win?!" City Lord No. 4: "My residents are all cowards, what should I do if no one dares to fight?" Suddenly one day, the city lords discovered why Cheng Qisheng had never complained? And why did she level up so quickly! Cheng Qisheng looked at the hundreds of millions of people in his safe city. The residents were loyal to her as the Creator God, loved fighting, and knew how to manage automatically... Even if you say it, you won't believe it. ——I won all the way to the Lord of the Planet. Purpose: Everyone should pursue a happy life and open up a better future
