Black Iron Order: Stars Falling from Mountains and Rivers

A blacksmith couple from a poor family found an abandoned baby in infancy. For twelve years, they used forge sparks as lamps and stoneware bowls as dishes, turning the scars on their bodies into wings to protect the baby. Young Lin Qiubai uses mathematical mysteries to understand the true meaning of martial arts, but he does not know that the broken sword repaired by his adoptive father coughing up blood and the bronze mirror wiped by his adoptive mother late at night are all the prelude to the troubled world. When the merchant who collects mountain goods reveals his chi-kissed jade pendant, when the star map of Xuan Tieling illuminates the thunderstorm, and the blade tempered by the warmth of the world finally breaks open the blood-stained mystery of his life experience.
