Immortal Longevity, Beginning with a Divine Cauldron

No System, no transmigration, a slow-paced, traditional cultivation story. His parents starve to death, and he and his sister are separated. His genius sister is recruited by an immortal sect, with a boundless future ahead of her. But he, with his mediocre aptitude, is sold into a black mine, reduced to an ant with no control over whether he lives or dies. Deep in the dark mine, after narrowly escaping death, he unexpectedly obtains a mysterious little cauldron. A drop of vital blood awakens its heaven-defying power! Ordinary spirit herbs transform into rare treasures overnight! Watch as a mere mine slave uses a divine cauldron to roil the cultivation world, master both alchemy and martial arts, fight his way to the Ninth Heaven, and make this rigid world tremble before him alone!
