When rumors of a secret armory that was left behind by Rong Xuan, who was killed by the Five Lakes Alliance and other heroes 20 years ago in Mount Qingya, start to resurface through a nursery rhyme, the balance of the martial world starts to shift as people begin their hunt for the treasure.

Wen Ke Xing apologizes for his maid's actions to Zhou Zi Shu. But, he recognizes his martial arts technique as one from the Four Seasons Manor, and suspecting his true identity, decides to follow him. Zhang Cheng Ling offers his name card to Zi Shu as he considers him a new found friend and would like to help him.

Wen Ke Xing asks Zhou Xue if he really wanted to get into something he had no idea about by accepting Zhang Cheng Ling. Zhou Xue guesses that the return of Ghost Valley and the sect's massacre meant that they were after something.

Zhang Cheng Ling, Zhou Xue and Wen Ke Xing are surrounded by the beggar gang, who asks Cheng Ling to follow them to the Five Alliance. Zhou Xue fights them off and takes Cheng Ling away.

Bei Yuan tells Ah' Xu that Prince Jin was not after the armory, but after a secret left by his tribe about a place which would help the country's occupants thrive well for a long time. The secret place was rumored to have a key belonging to six people with different surnames. Ah' Xu's father had tried to find its location along with his friend, Qin Huai Zhang.

Ah' Xu, Lao Wen, Gu Xiang, Cheng Ling and Cao travel together. They are however attacked by the Scorpions. Shen Shen, who was still on the search for Gao Xiao Lian encounters Lao Wen and Ah' Xu. They fight off the attackers together.

Shen Shen, before departing, requests Cheng Ling to always take care of Gao Xiao Lian even if he doesn't marry her, to which he agrees. Ah'Xu enquires about Lao Wen's past to Gu Xiang, but decides to let the matter rest. Lao Wen has dreams recalling his entry to the Ghost Valley.

Ah' Xu and Lao Wen have a talk over wine where they share their memories. Ah' Xu decides to stay at Four Seasons Manor forever with Cheng Ling until Ye Bai Yi returns, welcoming Lao Wen to come over anytime. Gu Xiang and Cao Wei Ning sees Gao Xiao Lian being taken away by Tao Hong and Lv Liu in disguise.

At the Five Lakes Alliance monument, Ah' Xu spies Pretty Arhat from the Scorpion assassin organization. He finds Lao Wen and they observe the discussion together.

Long Xiao is carried in a basket by Cheng Ling while Ye Bai Yi, Ah' Xu and Lao Wen travel by foot. Their journey to Longyuan Cabinet goes awry as Lao Wen accidentally triggers a trap on the bridge. Ah' Xu and he manage to save Cheng Ling, but are thrown into a cave with drug men created by Long Xiao.

Ye Bai Yi presses Long Que to reveal the secret of the armory as he was Rong Xuan's master. He had run away from Mount Changming after Ye Bai Yi had stopped him from practising the Six Combined Cultivation technique, which he deemed to be dangerous. Back at Yueyang sect, a gloating Zhao Jing speaks with the tablets of everyone who had passed away.

Long Que gives the location of a map of Longyuan Cabinet and the armory to Zi Shu, asking him to hand over the latter to Ye Bai Yi. He also informs that he had written two books regarding the mechanical inventions he had created. Zhang Cheng Ling takes over the task of continuing Longyuan Cabinet and Four Seasons Manor's legacy.

The Scorpion King orders the Ghost Valley to annihilate the Fairy Ray Sect. The ghosts are hesitant to commit the crime as the sect had never done anything to them, but they are threatened into doing it. Happy Ghost and Lovelace starts seeing through Zhao Jing's true intentions, realizing that he is no different from their crazed leader Wen Ke Xing, who had skinned the previous Valley Chief alive to claim his place as the leader of the Ghost Valley.

Ah'Xu, Lao Wen and Cheng Ling reach the now dilapidated Four Seasons Manor. Gu Xiang who was on her way to Gentle Wind Sword Sect along with Cao Wei Ning, sees a disciple of the Yueyang sect being attacked for supporting his deceased leader Gao Chong.

Xie' er awaits Gentle Wind Sword Sect leader Mo Huai Yang's return. Back in the sect's mountains, Gu Xiang tells Cao Wei Ning about Wen Ke Xing and her past after he expresses his sincere feeling for her. Da Wu cures Lao Wen who wakes up after several days and learns about Ah' Xu's capture.

Ah' Xu learns that Cheng Ling had come to know about Lao Wen. He attempts to reach Lao Wen to warn him, but instead over hears about the Chief of the Ghost Valley being cornered by the Five Lakes Alliance.

Xi'er lets Qian Qiao free, giving her the antidote to the Slave Voodoo venom and asking her to escape with Yu Qiu Feng. At the Heroes Conference, Zhao Jing and the rest discuss about who has to lead the Siege of Ghost Valley.

Tragicomic ghost, who maintains the list of unfaithful, captures Mu Yun Ge of Broken Sword Manor and holds a wedding between him and the memorial tablet of the girl he had deceived.

Wen Ke Xing asks Zhou Xu why he had accepted Cheng Ling as his disciple to which he responds that his master had taught him to be brave and take paths no one had taken and trust people who are hard to get to know. He chooses Lao Wen as the one he was willing to trust.

Gao Chong realizes that he was trapped. Shen Shen refuses to back down and challenges the other sects into a fight. The Gentle Wind Sword Sect leaves the arena, despite being one of Gao Chong's trusted friends. Zhou Xu rescues Cheng Ling and Lao Wen joins in to help him. The Five Lakes Alliance Monument is destroyed by the beggar sect disciples.

Gu Xiang treats Cao Wei Ning at Mount Hua sect. He tells her about his bad dreams in which he was unable to save her. Zhao Jing actively starts to work openly with the Scorpions, killing everyone who dared to slander him. He concludes that Gao Chong had cleverly planned to destroy the armor to end the war for the sake of the Jianghu while the actual shards are safely hidden.
