The Dead City.

The Ivairis and Fleuran kingdom has been at war for a long time, and the Ivairis kingdom has always been victorious 'cause of their mighty knights and good weapons. But that wouldn't last forever, coming prepared and attacking at the right time, the Fleuran kingdom brought about destruction to the Ivairis kingdom. Hugo, an 18 years old teenager was a native of the Ivairis kingdom, and he died along with his family due to the destruction. He was given a chance to live again, but his transmigration wasn't much of a pleasant one. He found himself in a world that had undergone annihilation, a world that was experiencing the apocalypse filled with bizarre creatures. Granted a system, Hugo would have to survive this world, pass through whatever challenges. And who knows? He could bring an end to the apocalypse... Note: This book has three prologues, that's the life of the MC before he died and found himself in a post-apocalyptic world. You might find the first prologue boring, but don't judge the whole book 'cause of that. Try skipping the prologues and jumping straight to the fourth chapter, that's when the main story starts. If you find the prologues boring, skip them.
