Su Ling'er is the top salty fish in the 21st century. Her life creed is "I can lie down and never sit down" and my life goal is "my hairline will never move back". Once she traveled back to the 1970s when supplies were scarce, she originally thought she was going to start a tragic scenario of "facing the loess and turning her back to the sky", but unexpectedly, she was bound to the "dream replacement system". As long as he falls asleep, the soul of the "unlucky guy" who travels through parallel time and space will spend three days in the dream and one night in reality. The materials, skills, and physical condition in the dream can all be brought back to reality. The only price is - exhaustion in the dream, and the hairline in reality moves back. Thus, in these passionate years, Su Ling'er started the magical life of "sleeping during the day and being the king of scrolls in the dream".
