Rules for a Chaotic Age

Twelve years after the disaster, the only rule in the old city is that there are no rules.

Xu Yi only wants to survive by guarding his little pile of salt.

Until one day, someone tells him: Someone's contaminated the well on South Street, and three factions are about to go to war over the water.

Everyone thinks chaos is about to erupt.

Only Xu Yi spends the night trading his salt for water, then uses a few barrels of it to win the hearts of people from three streets.

Later, the most powerful faction in the old city asks him: What are you after?

He says, "I want to see if we can still reason with each other in a year of disaster."
