末日将至，还好我有模拟器！

The end of the world is coming, luckily I have a simulator!

Capítulo 1 Se acerca el final, por suerte tengo un simulador!

Seven days later, the doomsday comes. Fortunately, you have a simulator...
[The doomsday simulation has begun]
[Please choose one of the following three talents: 'Devil's Contract (Gold)', 'Resurrection of the Dead (Gold)', 'Mirror World'...]
[...]
[On the first day, the sun no longer rises, and the doomsday arrives as expected...]
[On the second day, the temperature drops sharply, and citizens scramble for supplies...]
[On the third day, safe houses are harmful to health, so staying there less is the best way... You are crazy, leave your safe house, and look for mystery]
[...]
[On the forty-fifth day, there is no difference between reality and dreams, you encounter a strong enemy... You die]
[This simulation has ended]
[Please choose one of the following three rewards: 'Devil's Contract'...]
If you use the simulator properly, you can get a powerful doomsday reward every day before the doomsday.
So, when the countdown to the doomsday ends, you are already ridiculously strong...
