Reborn as Petunia Evans with a System - Chapter 20 - 19

76 years ago, the world changed. Or rather, should I say it evolved? Even so, this, “evolution” came at a price. Or maybe, the 'price' is what caused the evolution in the first place. What is this 'price', you ask? An invasion. Monsters from another world. Creatures we've only known through fork lore, myths and fantasy novels. They came from portals, known as Dungeon Gates, threatening all of mankind as we knew it. So in order to fight this catastrophe, the evolution happened. Half of the world's already large population Awakened as superhumans with Skills, Spells and Special Attacks all so they could pass through the Gates, enter the Dungeons and clear them. One by one. Thus marked the beginning of the Great Age Of Warriors.Name's Raid. And I'm one such Warrior. Now here's the kicker. I'm an F-Rank. The first one in history. Due to my low Mana Capacity, I could only choose one Class. The infamous Blacksmith Class. A Class no one even looked at twice, because weapons of mass destruction can easily be created with today's technology without much hassle. Now I'm faced with the reality of being seen as the weakest Warrior of all time, but you know what? To hell with it all. I'll make the most of the cards I've been dealt, even if those cards are...pretty shitty cards. I'll show all those High-Ranked Warriors what's what. They'll know my name whether they want to or not.Tag along for the ride if you're interested. Because once I get going, I'm not stopping until I reach the top.

The rivers and lakes carry wine with swords, the waist is slender and the palm is light.

The young man carried a long knife on his shoulder, and hung wine on his waist, striding forward, but the rivers and lakes in his heart were vaguely visible.

Turning a page in the book of troubled times, the rivers and lakes have been raining nightly for decades.

Looking back suddenly, the world has been shattered.
