Even Given the Worthless ‘Blacksmith’ Class, I’m Still the Strongest

In a world where God bestows everyone with a job and a divine weapon upon their coming of age, an overpowered weapon is the ticket to living the best life. But Lerius, a boy who comes from an innkeeper family, is given the weakest job, blacksmith! Just when he thinks his future is bleak, he finds out that his divine hammer IS overpowered: it can appraise and infinitely recreate anything it breaks! Thus begins a quiet life of rising to the top through the creation of all things!
