Stellar Stone

In Shang clan city’s third inner city, dens sell stellar stones beside old man stones, pushing cart stones, and cold ice stones. Grades run scrap, low, medium, high, or super, with prices from a few primeval stones up past a hundred thousand. ^{ch. 276}

How the fossil forms

A clerk explains the general gambling rock process: a Gu that is badly hurt or starving may hibernate, rock layers build around it over long time, and the law fragments in the Gu make the fossil look unlike ordinary soil. Shape often hints at the Gu inside: star dart Gu favors a dart form, star arrow Gu a long pointed form with a spreading end, and shooting star Gu a round body with a tail. More shining stars raise the chance of a live Gu and a higher rank. Dissection of a stellar stone should use magnetism rather than acid methods suited to other rock types. ^{ch. 276}

Cube fossil and legendary Gu

One scrap grade stellar stone in a third inner city gambling den is cubic like a brick and sits under a counter leg as a prop. In Fang Yuan’s prior life, a tripped Gu Master bought and opened it, revealing a legendary Gu that made its owner a famous strength path Gu Master. In the present timeline that cube is empty after a public dissection, because Wu clan spy Li Ran planned to swap in a matching fake made by Wei Shen Jing that already sealed the real worm. ^{ch. 276} Fang Yuan steals that sealed stellar stone from Li Ran’s flowerbud Gu, then forces cooperation and opens All-out Effort Gu from it at Lan Chao gambling den. ^{ch. 283 ch. 285}
