Arsenal guard Jiang Che detonated the arsenal to perish together with the enemy, but waking up, he became a starved orphan in Xiahe Village in the second year of Jianwen, with a portable arsenal appearing on his body. He went into the mountains to hunt tigers and sell bones for grain, protecting the family of Xu Daniu who saved his life; to seek a path to survival, he signed up for the military, rising from a recruit in the Yanshan Left Garrison to the Prince of Yan's personal guard, his archery skills and courage shocking Zhu Di, and with a "killing blade, living sword" taking on Yao Guangxiao's interrogation. The Prince of Yan appointed him the first head of the Secret Guard Bureau, and he brought brothers like Zhou Han and Yu Qing, spying, beheading, and executing first and reporting later amidst the fires of the Jingnan campaign, stepping by step brewing from a mountain village orphan into the sharpest blade in troubled times.
