After materializing in the Hall of Ten Thousand Races, Cheng Zongyang rummaged through his Preservation Space and finally found a Talisman.
—Poison Testing Talisman
As the name suggested, it was a Talisman used to test for toxicity.
He had bought it from a stall vendor in Ice City; it was something a Talisman Maker had accidentally concocted. It was intended for adventurers entering Secret Realms, allowing them to test whether certain places or items contained imperceptible toxins.
He had found them interesting and bought a few.
The Talisman Paper was white, but the more potent the tested poison, the more its color would change, progressing from white to off-white, light gray, gray, dark gray, blackish-gray, and finally, black.
The darker the color, the higher the toxicity, all the way to black!
