The End of the World: I Dominate Just by Playing Games?

The apocalypse suddenly came, and almost 99% of Blue Star's population turned into zombies that preyed on people. Li Yu thought this was the coming of hell, but he didn't expect that he unexpectedly got a high-tech mobile phone. In this mobile phone, there are various games that he played in his childhood. He thought that these games would only bring him some boring entertainment before his death, but who would have thought that after he killed the first mob, the gears of fate began to turn. Kill ordinary soldiers and gain +1 constitution! Get gun props and attack speed +1! Pass the level boss and get all the combat experience of the game characters! At this point, Li Yu embarked on an invincible road. Waiting for him in front is a rational and capable beautiful CEO, a charming and mature landlord, a pure and lovely college beauty, and a heroic and beautiful policewoman... Years later, Li Yu looked back and realized that he had led his harem to dominate the entire apocalypse!
