- Description from novelbuddy

In the year 2057, the world has become a corporate-run utopia for the super-rich, and a hellhole for all the rest. Catherine 'Cat' Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon. A cyberpunk magical-girl alien-invasion LitRPG.It’s exactly as wild as it sounds.

Lyu Liang was an ordinary young man who was supposed to live a mortal life with his father in a small village. However, a wonderful opportunity led him into the Virtual Land where he learned about his unusual origin and started his dual cultivation journey—to be a Devilish Immortal. There were six races in this world: immortals, humans, devils, demons, ghosts, and spirits. Lyu Liang had access to any of those realms. Whether he would be a great Devilish Immortal was not up to his race, but his will. For him, it was not important to be the most powerful immortal and to be worshiped like God. He eventually chose to live a secluded life with his lover.
