Heaven was the chessboard, stars the pieces. Only in a cosmic dead zone as unusual as the Burial-Star Sand Sea could a battle be fought this way.
After the two sides separated, Yi Xuangong explained to Wang Ping:
"Every Household's Daoist grounds have a special artifact called a [Tomb Star], fashioned after the [Grave Star] at the center of the [Burial-Star Sand Sea]."
"A [Tomb Star] is extraordinary. It can guide the flow of the Star Sand Sea. Once enough [Tomb Stars] completely seal off the area around a set of Daoist grounds, they can draw the entire sea of Star Sand crashing back in, dragging those grounds within the [Grave Star]'s reach with irresistible force."
"That is terrifying."
Yi Xuangong's voice grew grave. "To date, every set of Daoist grounds dragged within the [Grave Star]'s reach has been swallowed whole."
"Including the cultivators inside."
"Unless they flee beforehand, they'll be buried with their Daoist grounds... But refining [Tomb Stars] also benefits the grounds."
"It strengthens their foundations in the [Burial-Star Sand Sea]."
"So in a battle between Daoist grounds, the attacker aims to surround the defender with [Tomb Stars], while the defender tries to consume as many [Tomb Stars] as possible."
"The attacker wins by completing the encirclement. The defender wins by consuming enough of the attacker's [Tomb Stars] to make the assault unsustainable... As for the fighting between those two outcomes, each side sends cultivators from its Daoist grounds to duel one-on-one. Both strength and resources matter."
The former came down to the cultivators' abilities.
The latter depended on how many [Tomb Stars] they had. With enough of them, even a weaker side could wear its opponent to death through one battle after another.
"So that's how it works..."
Wang Ping patiently listened to Yi Xuangong's explanation, then
