In the ancient Yi Kingdom, Junwangyu is in the ancient Yi Kingdom. Qin Wentian, the adopted son of the Qin family, has been weak since childhood. The Qin family was forced to send him to the Bai family for marriage. He has been living under the roof of others since childhood. Later, the Bai family broke the engagement in order to curry favor with the Ye family in the imperial city, and even wanted to take Qin Wentian's life. He escaped, but the royal family changed dramatically. King Yi was in a coma due to severe illness for a long time. The regent Yi Heng wanted to seize power and usurp the throne. The Qin family, descendants of loyal heroes, was charged with false charges and the entire family was executed. The remaining Qin children fled to the northwest, and Qin's father and others were taken to the imperial prison, but Qin Wentian escaped and vowed to rescue his father the demon, remove the traitor, and reorganize the Yi Kingdom. During this period, Qin Wentian met close friends Fan Le, Ruo Huan and others, and joined the famous martial arts school Jiuhua Gate. However, he unexpectedly learned that the impoverished Prince Yi Wuwei was hiding in Jiuhua Gate. Qin Wentian and Mo Qingcheng, the eldest granddaughter of the Mo family, protected Yi Wuwei together. He was wise and alert, and was able to deal with the coercion and inducement of Yi Tianjiao and the dark schemes of his grandfather Qin Hao. He crossed the treacherous and ever-changing wind and cloud fog, and was always able to turn danger into safety. In the end, he assisted the wise monarch Yi Wuwei to ascend the throne. After that, Qin Wentian was indifferent to fame and fortune, and stayed in Jiuhua Gate with Mo Qingcheng to protect the Yi Kingdom.
