Shen Ci, a top student in the Department of Modern History, accidentally traveled through time and became the bullied illegitimate son of a declining family in the Canglan Kingdom. At the beginning, he was severely beaten by his brother Shen Yue, but he narrowly survived because of a word that accurately grasped the family rules. The head of the family, Shen Yuan, threatened him with a crisis at the silk shop and gave him three days to resolve it, otherwise he would be expelled from the family.
Shen Ci relied on modern marketing thinking to dispel the "epidemic" rumors, and revealed his true brother's evil deeds to the public. Accidentally activating the mysterious jade pendant in his arms, he obtained the remnants of internal skills and mental skills, which attracted the secret attention of Xuan Chen, a master of martial arts. In the family trial, he won two games in a row using modern fighting skills, but was assassinated by Shen Yue and exposed by Xuan Chen in time.
When sorting out the accounts, Shen Ci discovered the secret of the collusion between the family and the capital officials, and the jade pendant was actually a token of the "Tianji Pavilion" that was said to contain the world's secret treasures. Forced to go to the capital to participate in the Autumn Period, he will bring his wisdom and jade pendant with him to survive step by step in the court intrigues and rivers and lakes disputes. He will transform from an abandoned son in the cold courtyard to a legend that stirs up the Three Kingdoms. He will also uncover the ultimate secret of Tianji Pavilion and his own rebirth.
