MTL - Cthulhu Gonfalon - Chapter 154

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.

Chu Nan was just an ordinary student, but because of an accident, he obtained the data collection, analysis and processing ability equivalent to the most advanced optical brain.

A huge disaster [Dark Game] sweeping across the multiverse has come.

When all the players in the game die, the entire civilization will be destroyed together.

Zhang Feng took the last artifact of mankind and was reborn from the future before the beginning of the dark game.

First of all, the first step is to start the game with a life of 100 years, and extract the SSS-level talent [Almighty Power].

The journey to the gods begins here!
