Zhu Yuanzhang founded the country with martial arts and was born in the Mingjiao, a martial arts sect. After taking over the world, he was well aware of the threat of the martial arts, so he suppressed the various martial arts sects by force and forcibly collected the secrets of each sect. However, he felt it was a pity to destroy them, so he hid them deep in the mountains and drew a treasure map called Mingtu.
After the death of Taizu, Jianwen succeeded to the throne and was eager to reduce the feudal vassal. King Zhu Di of Yan rebelled in the name of "Qing Jun Side" and eventually invaded the palace. Emperor Jianwen's whereabouts were unknown. Mingtu also ordered the commander of the Jinyi Guards to take Mingtu to live in seclusion somewhere under Emperor Jianwen's order.
Ming Chengzu then set up the Dongchang again, under the direct command of the eunuchs, and finally found out the whereabouts of Ming Tu, and a bloody storm started from Ming Tu.
