A car accident before the college entrance examination examination room actually caused the modern boy Li Chengqian to crash into the Tang Palace in the second year of Wude's reign. He became the eldest son of King Qin Li Shimin and the eldest grandson of Li Yuan.
Others who traveled through time either fought for power or avoided misfortune, but since he started talking at the age of six, he had concealed his talents and acted as a "child prodigy": he coaxed Li Yuan to favor him and Li Shimin favored him. He secretly took the four girls, Mei, Orchid, Bamboo and Chrysanthemum, as his confidants, built an intelligence network called "Yunying", and even Zuixian Tower and Weaving Workshop became his "secret strongholds".
He used modern ingenuity to modify silk reeling machines and create comfortable underwear, making "Chang'an beauties" popular in Chang'an. In the secret power struggle between Li Jiancheng and Li Shimin, he used cloud shadows to intercept secret letters and defeat poisonous schemes, silently paving the way for Li Shimin.
When the swords of the Xuanwu Gate pierced the dawn, and when the forces of the Five Surnames and Seven Hopes occupied the court, this Li Chengqian with a modern soul was no longer the rebellious prince in the history books. Instead, he mastered the chess game and secretly controlled the situation. He wanted to carve out a different legendary path in the turmoil of the early Tang Dynasty.
