During a severe drought and famine year, starving people gradually rise. The protagonist accidentally time-travels, possessing a set of methods compliant with the contemporary laws capable of creating a true gold system. Initially thinking holding gold would ensure safety in a turbulent world, reality fiercely splashes cold water, as food is the true hard currency in disaster years. Commoners, starved to the extreme, recognize only food rations, not gold and silver. Clutching gold and trying to trade for a bowl of porridge everywhere hits walls, repeatedly staging embarrassing farces of wanting to show off but failing to pull it off. While continuously generating comical jokes and holding back the stifling frustration of 'having money but no use for it,' he gradually discovers that behind this great drought lies the hidden mystery of a levee destruction case and account book deficits. The main plot features a comedic contrast opening with infinite gold, ultimately claiming the world.
