After Dressing up as a Useless Prince, I Rely on Black Technology to Win the Heir Apparent

The modern social animal travels back to Ye Xun, the deposed prince of the Xia Dynasty. At the beginning, his engagement was broken off by the God of War Princess and a famous and talented woman one after another. He lost his salary and fell into a dilemma. With modern knowledge, he gained a foothold by starting a business through poetry and soap. He was involved in the dispute between the princes for the right to inherit the throne. He successively smashed the plots of villains such as the third prince and the eighth prince. He invented body armor, improved salt and paper production, went on diplomatic missions, and went to the border. Guan Da defeated the enemy army, joined forces with the God of War Mu Lingshuang, and the talented Shangguan Yunqing to disintegrate the influence of his relatives, and was finally granted the title of crown prince in the Ancestral Temple based on his talents. Throughout the process, modern thinking overcame ancient intrigues, and both humor and passionate intrigues went hand in hand.
