While Others Level Up, I Cultivate Immortality: Surviving Until the Great Ascension

One day, I crossed over, and a game descended into reality. In this world, everyone can change their profession to become a professional, entering dungeons and defeating bosses to level up.

Awakening to become the only hidden profession, the Cultivator, I enrolled in the highest institution of the Great Xia. I originally thought a smooth path awaited me, but unfortunately, I couldn't defeat monsters to level up at all. After four years of university, I remained a mere Qi Refinement stage cultivator, struggling to even graduate.

Fortunately, I awakened a golden finger, the 'Life Simulator.' By paying energy, I could simulate the future and bring back the cultivation levels, items, and more from the simulations into the real world.

However, in the simulated future, fifteen years later, an alien race launched a massive invasion of reality, leading to the downfall of humanity.

With my cheat, I chose to survive and develop, continuously enhancing my strength through the simulator, becoming a hidden big shot, quietly resisting the alien invasion...

ps: This is a simulator story, leaning towards anti-trope farming and development, with a behind-the-scenes flow...
