From Overlord To Multiverse. - Chapter 58 - 57: Making Equipment.

- 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.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

That year, she made a run for it while pregnant. He was a powerful figure in the Malacca Strait, commanding respect in both legal and illegal circles. He allowed no one to cross him. So, at the engagement party when she was 25, a stranger in black claimed that the bride had taken his virginity and insisted that she take responsibility and return his... child.“Do you also want to marry me?” she asked him. Although the wording was wrong, they were both getting married, so he agreed to “marry” her. Having a child and taking the wife's surname seemed like no big deal to the big boss. Surprisingly, he decided to retire and become a stay-at-home dad, shocking his brothers!
