The Useless Holy Mage and the Apocalypse

Jake received the rare profession of a Holy Mage, but he couldn't fully harness its power. Despite 15 years of rigorous training, he could only use his magic to alleviate the fatigue of his party members. One day, Jake's life took a dramatic turn when he discovered that Sophie, his kind-hearted girlfriend, was secretly involved with Alex, the influential party leader. When Jake confronted them, Alex ruthlessly expelled him from a guild. To make matters worse, Jake was attacked by Alex's men, forcing him to flee and ultimately fall off a cliff to his death. However, the deity did not abandon him. The divine being granted Jake a new life and asked him to help a world overrun by zombies. In this ravaged land, Jake must use his newfound magical powers to protect and aid the people against the encroaching darkness.
