During the Jinghe period of Daning, Su Yu, a scholar from a poor family, was deposed from his first imperial examination because he angrily criticized the powerful for cheating. He returned to his hometown to teach and studied hard. By chance, he met the prince Zhao Huan who was on tour incognito. He was appreciated and supported by him. Three years later, he competed again in Chunwei and won the championship in one fell swoop.
Su Yu, who passed the first place in the imperial examination, entered the court as an official, but due to his relationship with the prince, he became a thorn in the side of Prime Minister Zhou Yan and was framed repeatedly. Fortunately, with the help of Lin Waner, the daughter of the Minister of Justice, he saved the day several times, and the two gradually fell in love.
There was an emergency on the border, so Su Yu asked Ying to go on an expedition, strategizing as a civil servant, and repeatedly defeated the enemy. Zhou Yan took the opportunity to frame him for treason and threw him into prison. Lin Wan'er risked her life to collect evidence, and finally exposed Zhou Yan's conspiracy to collude with foreign enemies, and Su Yu was avenged.
After that, Su Yu was promoted to Minister of the Ministry of War, implemented military and political reforms, assisted the prince to create a peaceful and prosperous age, and joined hands with Lin Waner to write a legendary life of a poor scholar.
