Rebirth of the Villainous Female Boss - Chapter 566 - 540: Reminiscing About the Past and Getting Drunk

A pair of young girls that appear to be the same age act like a mother and a daughter. They are on a journey for one reason: to obtain a medicine that will stave off the daughter’s disease. Killing demons, deceiving people, and giving her everything in hope that there’s a way of rescuing her daughter. This is the story of their fragile hope and overwhelming despair.

Humanity was on the brink of destruction. Muyoung, an assassin from the Forest of Death, fell to his knees. There were corpses all around him. For years, he had worked for the Forest of Death and had finally been able to eradicate them. Now, he, himself, was about to die. He closed his eyes as he felt his heart stop beating.

This stands at the forefront of strategy guides to Life (a shitty video game)!
