Ch. 221Fire Tempers True Gold · Essence Blood Revealed
Cheng Xi oversaw a successful new ironmaking process at the Mount Li Workshop, but the iron revealed a trace of Gonggong’s Essence Blood. After attackers sabotaged the workshop with cursed poison fire, Cheng Xi secretly extinguished it and the damage exposed a dangerous essence-blood crystal in the furnace lining.
- Cheng Xi directed Gongshu Sheng and the artisans through a data-guided blast-furnace smelt that produced unusually pure, tough iron.
- Cheng Xi noticed a ghostly blue glimmer in the iron, and the system identified a possible link to Gonggong’s Essence Blood.
- Black-clad intruders poisoned the coke yard and air inlets, setting off corrosive green flames that threatened to destroy the workshop.
- Cheng Xi secretly froze the cursed fire and used a Jade Talisman’s Spirit Rain to clear the poison while concealing his actions.
- Gongshu Sheng found a glowing Gonggong’s Essence Blood crystal embedded in the furnace lining, and the system warned Cheng Xi that ancient beings might have sensed it.
