This world will soon be destroyed.
One day, Nino, a young man who is a lonely alchemist, regains his memory of the previous life and realizes that his world is just like a certain game.
And the fact that we are pushing for a villainous and difficult route to destroy humankind.
But when I explain it, no one can believe it.
Even so, I tried to scratch my feet, but it ended in failure and I was caught as a sinner.
Nino escapes from the royal capital with a short break and arrives at the village, which was the initial starting point of the game.
What Nino aimed at was a dungeon hidden in the immediate vicinity of the village.
If the ground is swallowed by the sea of fire, you can live underground.
Based on that idea, the young man who has acquired the power of training that is almost universal will start to create a safe base.
In a world that is about to perish, at least I try to save even the people around me.
However, people who have been displaced from their homeland gradually gather, and just building a base goes beyond Nino's wishes and eventually turns into a huge country.
