I Became a God in a Zombie World

When the apocalypse arrives, the protagonist accidentally enters a parallel universe. The world follows the same timeline, but the parallel world curses him. He journeys through the apocalypse, gets a cheat-like boost in life, and saves the world.

A zombie virus breaks out. Unlike the crisis in movies, where people bite each other, humanoid zombies are insignificant. What's terrifying are the violent birds and beasts that can get anywhere. We discover that they're growing more and more intelligent. The apocalypse has arrived. What should I do?
