My Two System Classes Are Overpowered

Transmigrated into a dying, talentless casual cultivator, Wu Tao faces a brutal reality: poisoned by evil spirits, he has less than three months to live. His last hope, a work-related injury claim, is cruelly denied by a corrupt overseer, leaving him penniless, expelled, and staring death in the face. Just as despair sets in, a familiar 'Cultivation Panel' from his past life game awakens, granting him two cheat-tier professions: an 'Item Refiner' with monstrous talent and luck, and a hidden 'Physical Cultivator' for unparalleled defense and devastating close combat. His only path to survival is to craft a life-saving talisman, but his first attempt at true refining ends in catastrophic failure, leaving him with one final, desperate chance.
