I Returned from Cultivating Immortality and Became a Ride-Hailing Driver

This novel is too childish, not to mention the Immortal Emperor~ Even if a monk in the Dacheng stage is seriously injured and cannot use magic, his bones and blood cannot be shaken by mortals. I can understand what the author is saying. Is the protagonist okay in the battle between immortals and demons? Is the fairyland gone? For example, the earth is a fairyland. If the world war breaks out and the earth explodes, everyone will be safe and sound. Does this mean? The high score of 9.6 Is even better than the 9.3 Mortal Cultivation of Immortality.

The plot doesn't make sense to me at all. . Why are the four people who came down from the mountain with a monthly salary of 8,000 yuan willing to kill people along with them?
