Simulation: I Don't Want To Be Hero Of Apocalypse

An apocalypse appeared where all animals started to mutate while everyone was helpless to resist it until the people with some who successfully evolved with the mutation started to get superpowers called 'Grace'.
But these powers were unique to everyone who awakened with no ranking to them except judging them from their workings.
Alex who had transmigrated into this world at this time of apocalypse was ready to be scared and try different survival tutorials he had seen in his previous life but his fate and luck were good as he contracted the "Life Simulator" that helped with his acquiring the powers from different worlds that turn into Grace at being redeemed.
Alex decided to lay low while helping others from behind the scenes to save the world while he hid his own identity and lived a leisure life.

ps: This is a story about a simulator, leaning towards a careful survival strategy, farming development, and operating from behind the scenes...
