Can you recommend some apocalyptic system novels with more than a million words?

I recommend the book "I built a floating city in the apocalypse" to you. This novel was written by the author, Ye Mai. It is a sci-fi and doomsday crisis novel. It has more than a million words and has a very rich plot. The story was about after the apocalypse, the game system entered the world, and the survivors began to change their classes and build novice villages and main cities. As for Fang Bai, the inheritor of the ancient high-dimensional mages, he broke the boundaries of the game and built floating cities in the sky. The whole story had the sense of crisis of the apocalypse, but also the creativity and joy of the game. Ru Lu's 2022 new book,"My Spirit Beast Evolved Again," is also very good. You can read it together. I hope you like my recommendation. Muah ~😗
