The Green Face of the Apocalypse

She was originally a demon princess in the heaven, but she was designed by the fairy war god to marry him. Once her relatives were killed and her tribe was exiled, even her own son was killed in front of her eyes. She hated her, but she still could not escape the fate of death. When she woke up again, she was an ordinary woman in the mortal world, but she didn't want to coincide with the end of the world, where human nature changes, morals are corrupted, the strong survive, and the weak are bullied. She has no powerful powers, nor endless supplies. No powerful abilities? It doesn't matter, let's let the zombies wake up on their own after being scratched. Is there no heaven-defying space power? It doesn't matter, let's find the materials to make a storage ring, and practice hard to open up our own little world. Lack of spiritual energy in the last days and unable to practice? It doesn't matter, we are demons, we can refine our body but not our Qi. Leading his younger brother to fight zombies, using the end of the world to accumulate talents, let's see how the demon princess can prosper in the mortal world. Survival in the apocalypse is difficult, zombies are powerful, and there are many strange things. These are not problems. The problem is where is the entrance to heaven?
