Face changing silver

Among normal immortal materials left from the Olden Antiquity Era and Remote Antiquity Era in the snowman and rockman treasury, face changing silver is named as a metal that can mimic any beautiful woman and turn into their face. Those antiquity stocks are nearly nonexistent by the present day and cannot be found in treasure yellow heaven. Fang Yuan moves the treasury into his sovereign immortal aperture after taking it from the two tribes. ^{ch. 1584}
