In the Dharma-ending Age, it is impossible for the earth to cultivate immortality. Humans on earth have developed an alternative way of using thermal weapons. However, this has aroused the fear of the immortal cultivating forces outside the earth. They believe that if allowed to develop over time, human beings on earth will inevitably leave the earth and bring huge disasters to the world of immortal cultivating. Therefore, he wanted to destroy the earth, but the supreme god of the universe did not think so. He believed that the universe should let a hundred flowers bloom and allow different development methods to exist, so he gave the earth's humans a chance to prove themselves. If they could use thermal weapons to achieve immortality in the world of immortality, the earth would be allowed to continue to exist. If not, they could only destroy the earth due to the pressure of the immortals. Four earth practitioners had been intercepted and killed before reaching the world of immortality. As the last practitioner, Lin Feng carries the last hope of the earth. Can he reach the world of immortality safely? Can he achieve the immortal position and save the earth from the fire and water under the malicious pressure of the immortals? Can a human being on earth who cannot cultivate survive in the world of cultivating immortals with only the fire of guns and fire?
