Crown Prince, the heir to the emperor.
"Gongyang Zhuan: The Fifth Year of Duke Xi" He Lin notes: "Crown Prince, Deputy Chief." (That is, the deputy position of the monarch). "Book of the Later Han·Zheng Zhongzhuan" says: "The crown prince is the crown prince." "Book of Jin·The Biography of Wang Ying of Chengdu" says: "The crown prince is the crown prince of the country." Also known as "Chu Yuan", "Chu Fu" (the abbreviation of He Xiu's note quoted above), "Chu Hou", "Chu Si", "Chu Liang", "Chu Er", are all nicknames for the prince.
Dragon Qi is the Qi of the Emperor.
Since ancient times, emperors who ascended the throne of God must have the true dragon's energy to protect their bodies. However, because each emperor's "Tao" is different, the dragon's energy has also been tainted with different breaths and no longer exists, especially those emperors who have left a reputation in history.
In addition to the emperors, those princes who were princes but did not eventually ascend to the throne of God will have a large amount of clear dragon energy gathered in their bodies.
The imbalance between dragon energy supply and demand led to the creation of this article.
That is the transaction made by the prince with dragon energy.
