What Does It Mean That You Have Ascended After Only Twenty Years of Cultivation?

In the millions of years of cultivating immortality, no one has achieved immortality. Since Hongmeng first opened, there have been so many strong people, so many geniuses, and countless people with extraordinary talents. They have asked for immortality and have pushed their cultivation to unimaginable heights, but they have all failed in the last step of becoming an immortal. No one has become an immortal, and no one has ever seen an immortal. For that slim possibility, the world of immortality has gone crazy. Ren Yu traveled to a mortal dynasty in a land of immortality. He thought he was getting a script for historical time travel, but he got a glimpse of the madness of immortal cultivators that has lasted for millions of years and has not yet ended. However, Renyu has poor qualifications, no luck, no adventure, no system, and only his character can be considered to be at full level. In the eyes of ordinary people, the road to cultivation can be seen at a glance. So, on the day when Renyu ascended to immortality after twenty years of cultivation: "I work hard every day to seize my apprentice, why is it not me but him who becomes an immortal?!" "I have been cultivating in the Holy Mountain for 20,000 years, why do you think twenty years is enough?!" "What do you mean, I've been a dog to that old monster all my life in exchange for top-notch skills, but you can practice the skills made up by random people as long as they make sense?!" "Doesn't the Great Road to Immortality not exist at all? Isn't it the wishful thinking of the world? How can you still go up there!?"
