- Description from novelbuddy

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.
