After seeing the Jin soldiers and barbarian troops beginning to scale the walls, the players defending the city immediately opened the sealed barrels beside them, holding their breath as they poured the already boiling water into them.
In an instant, an indescribable foul stench spread.
"Pour it down now!"
These large pots had been specially made and were fixed to the city walls with brackets to make tipping easier. After pouring, the pots, connected by the brackets, wouldn't fall off the wall but could be righted and refilled with water to be boiled again.
The contents of the sealed barrels were feces that had been prepared in advance.
This was the famous ancient "Jin Juice."
The so-called "Jin Juice" was essentially fecal water, also enhanced with various poisons like arsenic to further increase its toxicity.
These ingredients weren't added to the pots immediately, but only after the water was boiled, then it was swiftly poured out.
