BOOOOOOOOOOM—CRACK-CRACK-SHATTER!
Ten thousand [Rank 7 High-Explosive Blast-Runes] detonated in a synchronized chain of crimson fire across the three-mile concrete-and-star-steel span of the Three-River Megadam.
For forty years, the Three-River Megadam had stood as the pride of World #10’s civilian engineers, holding back a hundred-billion-ton inland reservoir a thousand feet deep. Now, under the concentrated internal sabotage of Long Aotian’s ten thousand blast-runes, the central two-mile section of the concrete wall pulverized into dust in half a second.
ROOOOOOOOAAAAAAR—!
A terrifying, one-thousand-foot-tall wall of pitch-black floodwater burst through the shattered dam at three hundred miles per hour. It was mixed with jagged ten-ton boulders of shattered concrete and poisoned with five thousand barrels of [Rank 7 Corrosive Heavy-Water] that Long Aotian had dumped into the reservoir to prevent any ice-element cultivator from freezing the breach.
The roar of a hundred billion tons of plunging black water shook the continental plates of World #10 so violently that citizens three hundred miles away were knocked off their feet.
Up on the remaining northern abutment of the shattered dam parapet, chained General Su Dingfang and his fifty captured garrison soldiers wept literal tears of blood. They watched the thousand-foot black tsunami hurtling straight down the narrow gorge toward the twinkling dormitory lights of Willow-Creek Boarding Elementary School less than a mile below.
