A Journey to Love (VOICE)

Ren Xin is sent to prison on suspicion of killing the empress. After that, she fakes her death and escapes to Wu. She changes her name to Ren Ru Yi. She's selected by the Crimson Guard to become a White Sparrow. She intends to locate the culprit who harmed the Empress 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, Ning Yuan Zhou opens the coffin with his palm. Ru Yi who is hiding inside the coffin is knocked to the ground.

When the Old Chief is alive, he arranges a marriage between Official Pei and Ning Yuan Zhou. As Ning Yuan Zhou ponders how to reject her, Ru Yi appears, acting all affectionate 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.

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. At night, Ning Yuan Zhou suddenly discovers that Ru Yi is missing.

Ning Yuan Zhou finds out that Zhou Ji An, a cavalry general, is stationing his troops to intercept them. To reduce their casualties, they gather info and forge letters to dupe their enemies. Zhou Ji An escorts the "fake diplomatic team" out of the pass.

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.

The current Right Guard of the Crimson Guard, Jia Ling, listens to the reports from her subordinates. All the evidence ties the death of Yue San Niang and Yu Lang to Ru Yi. And the Secret Agent of Chu must have disguised herself as Ru Yi. In the end, Jia Ling sends Zhu Ji to track down Ru Yi.

While everyone in the diplomatic team is soundly asleep, Ru Yi secretly meets with someone from the Crimson Guard. Prior to this, she intentionally leaves marks on the bodies of Yu Lang and Yue San Niang, aiming to draw out the mastermind behind the murder case.

Unexpectedly, Ru Yi falls into Qian Zhao's trap. Caught between the two, she finds it increasingly difficult to hold her ground due to her existing injuries. When Shi San learns that she is a Crimson Guard, he joins the fight. In the end, Ru Yi has no choice but to "hold hostage" Yang Ying.

Ru Yi's return and rescue of Yang Ying made Qian Zhao, Sun Lang, and the rest set aside their resentment for her. She and Ning Yuan Zhou realize their true feelings too. Ning Yuan Zhou tells Ru Yi that he's willing to have a child with her after the mission is over.

Since Ru Yi returns again, Qian Zhao, Sun Lang, and others have changed their hostile attitude towards her. They even invite her to join them in their planning. Due to the impact of the war between An and Wu, the contact with Six Realms Hall's branch in Capital of An has been blocked...

Ru Yi plans to lure the Crimson Guard to He County which is adjacent to Jing City to find out the truth about the annihilation of the branch in Capital of Wu. The general of Jing City is visiting them to deliver a secret letter from the empress of Wu. Ning Yuan Zhou is tasked to welcome him.

Ru Yi is shocked when she finds out that her foster mother from Wu has been held hostage by the Crimson Guard. Zhu Ji's subordinate Qiong Zhu threatens Ru Yi with her foster mother's life. In order to save Ru Yi, her foster mother slits her own throat with Qiong Zhu's sword.

Zheng Qing Yun tries to sway Yang Ying with both affection and reasoning, hoping to convince her to agree to elope and marry him. As Yang Ying begins to sense that something is off, especially when Yuan Lu, who has come to stop him, is harmed by Zheng Qing Yun, she finally grasps the situation.

Yang Ying is still unconscious. To avoid arousing suspicion among the people of An, Ru Yi temporarily disguises herself as Princess Hu Yang from Wu. However, no one expects the State Receptionist to address Ru Yi as "Master" in front of everyone.

Ru Yi agrees to meet Li Tong Guang and mentions that Wu is willing to exchange cities for the safe return of their ruler. He requests Ru Yi to sit down with her eyes closed. Just like what he did in the past, he sat beside Ru Yi's knees and enjoyed the nostalgic feelings he had in the past.

Ning Yuan Zhou smashes the cup and says that Ru Yi is his most respected lover and companion. He says that no matter if it's the female cavaliers under her or Ru Yi, they don't have the obligation to seduce other men. Mr. Du suddenly realizes the truth.

Ru Yi doesn't understand why Mei Niang didn't tell her the truth about Li Tong Guang when they were at Jinsha House. Mei Niang explains that it's because the feelings that Li Tong Guang has toward Ru Yi are not just an affection between a master and a disciple, but a passion of a man toward a woman.

Ning Yuan Zhou brings Li Tong Guang to the location of the secret passage, instructing Yuan Lu to destroy the passage. Li Tong Guang follows his instructions, ordering the Garrison General to strengthen defenses around Tianmen Pass and promptly reporting the matter to Emperor An.

After being inspired by Ru Yi, Li Tong Guang chooses to join hands with Ning Yuan Zhou. To show his sincerity, he even tells him the location where he buried the fallen brothers of Heaven Realm.

The ruler of An allows Yang Ying to enter the pagoda to see the ruler of Wu. Yang Ying lived in the cold palace most of her life. She rarely meets her brother, luckily, Ning Yuan Zhou gives her an old token, the Six Realms Hall Ring. Yang Xing Yuan recognizes her at first glance due to that.

Chu Yue knows an imperial edict cannot change. After they got on bad terms, Chu Yue's father, Duke Chu, asks her to get along with Marquis Chang Qing. That is why she visits Li Tong Guang, but Li Tong Guang still treats her coldly. Both of them part on bad terms once again because of Chu Yue's provocation and rude words.

Ru Yi finally found the culprit who annihilated the Crimson Guard Branch in Capital of Wu. However, before Jia Ling breathes her last breath, she hints that Emperor An is behind the death of Empress Zhao Jie. Ru Yi is shocked.

Yang Ying always hides her concern before Ning Yuan Zhou and everyone. She only admits she is afraid in front of Yuan Lu who is the same age as her. She is afraid of the violent ruler of An, the death of the envoy group to save his brother, and worries that she might die in An.

As Li Tong Guang is reconnected to his master, he's much happier. He even saves Chu Yue on the street when he's passing by. She develops feelings for Li Tong Guang. Ru Yi initiates her revenge plan. She makes the culprits behind Empress Zhao Jie's death pay by cooperating with Li Tong Guang.

Emperor An rages after hearing about First Prince's death. Not only did he request an extra 30,000 gold taels as ransom, but he also blamed his death on the Crimson Guards, who were innocent. He orders Deng Hui to select 20 members and execute them outside the palace.

Ru Yi wants to save the White Sparrows so she gives a prescription that can undo the Crimson Guard's poison to Jin Mei Niang and asks her to make many antidotes. At the same time, a separate unit is planning to raid the pagoda. Ru Yi suggests she can discuss the escape route with Li Tong Guang.

After Yong'an Pagoda is destroyed, Yang Xing Yuan is transferred to another place. The new prison is called Donghu Cottage which is located on an island. Ru Yi had been there before. With her help, Ning Yuan Zhou and his men make a meticulous plan to rescue the emperor.

After forging a sword from meteoric iron, Ning Yuan Zhou tempers the sword with his blood. Ru Yi names the sword "Mundane World". They promise to spend the rest of their lives together and to meet outside Capital of An after completing their tasks.

Ru Yi forces Li Sun to tell the truth behind Empress Zhao Jie's death. She tells the people about Li Sun's crime of colluding with their enemy and she wants Li Sun to promise to record the contributions of the Crimson Guard into the historical records.

Ning Yuan Zhou arrives at Liuli Fort of An which is away from Capital of An after days of traveling. Under Qian Zhao's careful treatment, Yang Xing Yuan finally regains his consciousness and hands over the Vengeance Edict to Ning Yuan Zhou.

Li Tong Guang retrieves Ru Yi's ash from Deng Hui's place. He builds a burial mound for her in the secret cave hideout they shared when they were young. That night, Yang Ying heads to the cave in secret to pay her respects to Ru Yi under the protection of Li Tong Guang's bodyguards.

Only Yu Shi San, Yuan Lu, and Sun Lang are left in the unit. They don't have much time to feel sad. All of them go to He County to make a report. Yang Xing Yuan is also willing to risk being captured by the An people and defend He County with Wu Qian.

Ning Yuan Zhou and Ru Yi find out about Northern Pan's attack on He County. Both of them think Li Zhen Ye and Li Sun are involved in this. He County is in danger. If they don't force Li Sun to send troops, the people of An, Wu, and even the Central Plains will suffer and be miserable.

During the coronation, Ru Yi disguises herself as a servant. She manages to hold the second price, Li Zhen Ye, hostage. Ning Yuan Zhou and Ru Yi expose what Li Zhen Ye and Li Xun did, from colluding with Northern Pan to betraying the country for their personal gain in front of all of the officials.

As the defeated party, Lord Zuo Xian of Northern Pan presents his jade seal to Yang Xing Yuan and Duke Chu. However, amidst the cheers of the crowd, the box containing the jade seal suddenly explodes, causing the instantaneous demise of Yang Xing Yuan and Duke Chu.

Before their departure, Zhang Song delivers the antidote to Ten-day Poison to Ning Yuan Zhou. Xiao Yan is amazed by Ru Yi's heroic actions. She gifts her hairpin to Ru Yi, making it convenient for her to act in the future.

Ning Yuan Zhou stands in the middle of the inn in He County. In his mind, he sees Yuan Lu, Qian Zhao, Sun Lang, and Yu Shi San in white, fooling around in the snow. Ning Yuan Zhou's eyes fill up with tears. And he makes a promise to Ru Yi that both of them will stay safe and sound.
