One day, when a novelist woke up from a restless sleep,he realized that he had transformed into his 12-year-old self.

At 79, Adom is an old mage who has known nothing but illness and regret. When the world finally burns and all hope turns to ash, at the last beat of his fading heart, a mysterious being appears in the dimming light with a simple question:“If you could try again, would you?”What's left to lose when you've already lost everything?A handshake seals the deal, and Adom wakes up on his old school grounds, sixty-seven years in the past. When everything is still possible. A second chance with all his knowledge intact, his memories preserved, and his youth restored.This time, Adom wants it all: to feast on food he's never had, to travel a world still full of wonder, to finally live the life he dreamed of. There's just, as always, one small catch—he needs to prevent the end of the world first.But as Adom will soon discover, changing history might demand sacrifices even greater than watching it burn...

Anton is a great-grandfather. He is living quite a happy life, despite his advanced age and declining health… until a group of cultivator bandits moves into the area. The nearby guardians of the area, the Order of Ninety-Nine Stars, are unable to track them down as they continue to ravage nearby towns. During one desperate winter Anton is out on a hunt when his family- his entire village- is killed or taken as slaves by the bandits. He lacks the strength to fight them, and he wasn’t even present for their arrival to die with his loved ones. At the pit of his despair, he wonders if he ever had any chance to change things. What could he even do? He cannot even pull his best bow, and his eyesight is failing. If he had been a cultivator… perhaps there might have been a chance, but he was decades- perhaps even most of his life- too late.Participant in the Royal Road Writathon challenge (2022)Notes on cultivation levels:There are five general stages of cultivation, though the fifth is extremely rare.
