Second Generation

In the future, human beings will be very technologically advanced and will be able to eliminate disease problems through technologies such as replacing their own organs and strengthening cells. The protagonist Mustard (Zhao Jiemo) is not only very resistant to this way of life, but also extremely skeptical of the history recorded by mankind. According to history textbooks, mankind once suffered a rare sunspot activity, and with the ensuing Ice Age, mankind lost its past history. However, when Mustard was a child, he accidentally obtained an "ancient book". The characters and scenes described in the book were completely different from modern society, which made him even more confused and hoped to find the real answer to history. In the end, Mustard learned the whole truth in a cave. It turned out that "sunspots" and "Ice Age" caused the epoch of history to be people's lies. Modern humans are just "mutants" caused by environmental pollution, and past humans have long since become extinct.
