Shen Yan, a frustrated modern highly educated man, accidentally traveled through an unknown apocalyptic dynasty and witnessed famine, corvee labor and war engulfing all living beings. He abandoned the shackles of the past and used modern rationality and knowledge as his blade. Starting from a bowl of relief porridge and a reform of farming, he gradually reconstructed the system and united people's hearts. On the ruins of the collapse of the dynasty, he earned a glimmer of life for the people at the bottom, and performed an epic of mortal struggle to rewrite the times.
