A Pure Qi Practitioner in the Strange Apocalypse

[Non-cool writing + growth-oriented protagonist + mortal flow + slightly weird + slow-burning + no harem] The story takes place in a small world that collapsed after the war between immortals, demons, and gods. The gates of heaven are permanently closed and the roads are cut off by thin and polluted spiritual energy. The monks hide in secret realms and linger on, unable to ascend. Demons and demons are causing harm to the world. The protagonist travels through time and awakens his special powers. With the talent of the sea of consciousness, he is not afraid of soul-type attacks and can be exempted from spiritual costs. He spent half his life searching for immortals and worshiped the immortal sect. Unexpectedly, the immortal sect, known as the famous and upright sect, is more evil than demons. The immortal cultivators of this era have completely transformed into evil cultivators. The protagonist escapes from the Immortal Gate and obtains the orthodox Qi-refining method from the ruins of ancient immortals. He refines human luck in the world of mortals and enhances his cultivation. Finally, the human luck is strengthened. He opens the gate of heaven and draws the pure spiritual energy from the upper world to save this apocalyptic world.
