Su Qing, a gold medal Sanda coach, was accidentally injured during a competition. When she woke up, she transformed into Chu Ruanyu, the frail and sick "Tofu Princess" of Chu State who had just experienced the country's collapse. In order to survive, she pretended to be weak to deal with the repeated temptations of the enemy generals in land battles, but when the assassins raided her, she subconsciously showed off her Sanda skills, breaking the illusion of a "weak woman". Since then, the two have gradually formed an alliance to restore the country from "happy enemies" who were suspicious of each other - Su Qing improved her Sanda skills into actual combat moves to train soldiers, while Lu Zhan secretly prepared roasted chicken legs for her in the name of "military supplies", secretly developing a love. In the process, they worked together to fight against the ambitious King Jing and the invading Beidi forces, resolve the crisis of traveling through identity exposure, and finally succeeded in supporting the new king of Chu to ascend the throne. Su Qing gave up her power and opened a martial arts gym, and Lu Zhan took off her armor to accompany her. The two continued to write a warm relationship in the daily life of fireworks, leaving behind a good story of "the Sanda princess protects the family and the country, and the tough guy general loves her".
