Uma jornada para o amor

Ren Xin is sent to prison on suspicion of killing the empress. After that, she fakes her death and escapes to Wu. She lives with a blind lady and changes her name to "Ren Ru Yi". Ru Yi intends to rest and recuperate. However, she's selected by the Crimson Guard Branch in Wu to become a White Sparrow, one of the lowest-ranking members. Thus, she uses that fact to her advantage and pretends to be an ignorant White Sparrow. She intends to locate the culprit who harmed Empress Zhao Jie once her inner force recovers.

Everyone from Six Realms Hall begs Ning Yuan Zhou to stay after his return. Ning Yuan Zhou knows he is badly hurt and should retire. When everyone leaves, Yuan Lu blames Ning Yuan Zhou for hiding the fact that he is still alive. Ning Yuan Zhou says nothing and opens the coffin with his palm. Ru Yi who is hiding inside the coffin is knocked to the ground.

It turns out that when the Old Chief was alive, he had arranged a marriage between Official Pei and Ning Yuan Zhou. However, due to Ning Yuan Zhou's imprisonment and exile, Official Pei is married to someone else. As Ning Yuan Zhou ponders how to reject her, Ru Yi appears, acting all affectionate. She grabs Ning Yuan Zhou's arm, pretends to be his cousin, and deliberately calls Ning Yuan Zhou "cousin" while trying to provoke Official Pei to leave.

Ru Yi and Ning Yuan Zhou reach an agreement. Ru Yi is responsible for teaching Yang Ying everything she knows about An. Once she's done, Ning Yuan Zhou has to help her locate the culprit behind Empress Zhao Jie's death. When he finds out that Ru Yi is "Ren Xin", he's utterly surprised even though he's the renowned Ning Yuan Zhou.

Ru Yi and Ning Yuan Zhou meet the other team members. Yu Shi San tries to court Ru Yi. Ru Yi shows his skills and makes Shi San and Qian Zhao concede to her. Since the Crimson Guard and Six Realms Hall have a grudge, Ning Yuan Zhou hides Ru Yi's identity by calling her a Secret Agent from Chu.

Ru Yi originally intends to control Ning Yuan Zhou with the Twin Butterflies, but with the help of Yu Shi San, Ning Yuan Zhou forces the Twin Butterflies out of his body in the next moment. Ru Yi is furious, and for a moment, Ning Yuan Zhou is also unsure how to handle the situation. At night, Ning Yuan Zhou suddenly discovers that Ru Yi is missing. It turns out that Ru Yi has just gone to the hometown of Yu Lang, which is nearby. On the one hand, she wants to use Yu Lang to verify the truth of what Yue San Niang had said, and on the other hand, she is seeking revenge for Ling Long.

Ning Yuan Zhou finds out that Zhou Jian, a cavalry general, is stationing his troops to intercept them. To reduce their casualties, the diplomatic team moves together. They gather information and forge letters to dupe their enemies. Ning Yuan Zhou heads to Zhou Jian's place, duping him by mixing truth with falsehood. Zhou Jian escorts the "fake diplomatic team" out of the pass personally.

Ru Yi and Yu Shi San go to Qingjing Mountain to find a Silver-ringed Snake to save Yuan Lu. When Ning Yuan Zhou arrives, he sees Ru Yi in danger. He pushes Ru Yi away which causes a relapse of his old injury.
