In the Apocalypse, I Lead the Fourth Calamity in Handcrafting Nukes

You have been personally chosen by the System to save the world! This System will do everything in its power to serve you!

[Congratulations! You've received your starting skill: Nuclear Peace Is a Blast!]

After transmigrating into the apocalypse, he became the savior the System had spoken of and gained the starting skill of crafting a nuclear bomb by hand. Its destructive power was immense, but unfortunately, it consumed a tremendous amount of energy and had a long cooldown.

But that's okay. He can use the System to create a virtual reality game and bring the legendary Fourth Calamity into this world! Forget the apocalypse. Even if it's the twilight of the gods, they'll hack right through it for you!
