My Savior Is the God of Destruction

I thought it was enough to travel through time to become a brave man and save the world. Until I discovered that the world's catastrophic disaster was exactly the "him" I was missing. Lin Fangzheng traveled to another world and was appointed as the savior by the gods. They gave him an oracle, a companion, and a holy sword with high growth potential and invincibility. He thought the goal was clear: to become stronger, fight against disasters, save the world, and then have a warm reunion, just like an old-fashioned storybook. But the closer we get to the truth, the more absurd the world becomes: Why do the seven legendary servants of disaster always say the same name? Why does the weird God of Destiny always cast an inexplicable glance at him? Why is the holy sword in his hand that kills disaster so similar to the "ideal" someone once described... When the holy sword, which symbolizes protection, points towards the one that brings destruction—— Does this world need to be saved or... Restarted?
