Secret Fire of Firewood Kiln

Chai Rong, Shizong of the later Zhou Dynasty, worked hard to govern and aimed at unifying the country. There are rumors in the world that the long-lost secret technique of wood kilns can not only produce peerless porcelain that is "as green as the sky, as bright as a mirror, as thin as paper, and as loud as a chime", but can also produce a strange material called "Xuan Porcelain Steel" - as light as bamboo and wood, but as strong as armor. Chai Qing, the master of Chai Kiln, was forced to leave the mountains and enter Bianjing due to a disaster that destroyed his family. He practiced the art of "heart fire" and "earth fire" in the crazy old man's clumsy old dragon kiln. He also met Zhao Qingyi, a female military supervisor, and was involved in the torrent of military industrial reform in the later Zhou Dynasty. Gui Jizi, the master of Baibing Pavilion, spent his whole life pursuing the secret technique, vowing to forge the "ultimate weapon" and pressuring Chai Qing step by step. From Bianjing to Heshuo, from the ancient battlefield of Gaoping to the front line of the Northern Expedition, Chai Qing gathered the three branches of secret skills in the flames of war and pursuit, and finally cast black porcelain steel in a state of "forgetting both things and myself". However, when the weapon was just ready, Emperor Shizong died of illness, Zhao Kuangyin and Chen Qiao rebelled, and the world changed hands. At a fork in history, Chai Qing made a choice that transcended his times. He sealed what he had learned throughout his life into a piece of celadon and hid it underground for future generations. Technology can break heavy armor, but benevolence can create peace.
