Cultivation of Immortality in the Last Days, Surviving Till the End

On top of the ruins, among the broken walls, a young man in ragged clothes was treating a dying old man. His technique was skillful, but his expression was indifferent, as if he had long been numb to life and death. People around him were talking a lot, some were sympathetic, some were ridiculing, and most were indifferent. At the top of the tower, he sat cross-legged, running his skills, and the spiritual energy of heaven and earth poured into his body crazily. A cold electronic voice sounded in his mind: "Congratulations to the host, your cultivation has broken through the first level of Qi Refining Stage." A sneer appeared at the corner of his mouth: "First level of Qi refining stage? Ha, with this level of cultivation, it's hard to even protect yourself..." He looked up at the sky, where a huge crack was terrifying, as if it was about to swallow the entire world. "I want to become an immortal." This novel and its characters are purely fictitious.
