There's No Other Way to Do It. If You Don't Practice Immortality, You'll Get Nothing.

At some point, a chaotic and strange mist appeared in this area. Desolate fog contains poison. If ordinary people smell it for a long time, they will deteriorate themselves and die prematurely. In order to seek shelter, the rich and powerful purchased the right to live in the city and relied on the protection of the practitioners to stay safe and sound. And those people from the outer city who have no background and power are called deserters, and they live and die in the wilderness. Huo Xiu, a desert man living in the wilderness, was accidentally discovered by people in the city. His appearance was very similar to the third son of the city lord. From now on, he will replace the Third Young Master and go to the 'Daoyuan Sect', one of the four major immortal sects in the Eastern Wasteland, to obtain an immortality pill.
