Xi Sanmei

Xi Sanmei was the Right Guardian of the Da Huanxi Sect, and the foster father of Qin Wuque (who was famous as the monk Shenxiu). He was a formidable Innate Realm expert, specializing in healing and poison martial arts. Xi Sanmei was ultimately defeated and killed by Xie Yan in the ruins of Ji Ye.

Personality and Traits
Xi Sanmei was a selfish and malicious man who would viciously kill anyone that stood in his way. He was not someone who would easily give up what he wanted, even making a few sacrifices along the way. Xi Sanmei had a particularly strong will as he was able to resist Xie Yan's "Despised By Gods And Ghosts Alike" technique. He was a middle aged man with gaunt features and a lean, muscular physique.

Plot
Xi Sanmei was the Right Guardian of the Da Huanxi Sect, the top ranked demonic sect of the Tang Empire. Years ago, he sent a four year old Qin Wuque to the rival Vermilion Bird Temple to spy on them. Qin Wuque was renamed as Shenxiu, a monk renowned for his scholarship in Buddhism. Thanks to Qin Wuque, Xi Sanmei was always one step ahead of the Vermilion Bird Temple.

Three months ago, the sect master of the Huanxi Sect was killed and infighting broke out among the Guardians. Xi Sanmei fled the sect after the Left Guardian injured him, damaging his cultivation base. During his search for a cure, Xi Sanmei ransacked one of the branches of the Vermilion Bird Temple, massacring several disciples and elder Hai Yun in the process, and prompting three of its elder monks chasing him into the Han Empire.

Xi Sanmei journeyed to Datong City where he discovered a Bodhi Rosary that could restore his cultivation. Unfortunately, it was auctioned to the Han imperial prince Di Xiaoyao, an avid collector of artefacts. Xi Sanmei shadowed Di Xiaoyao, who was travelling with Xie Daoyun and Shenxiu to the ruins of Ji Ye. A few days later, Xi Sanmei secretly meets Shenxiu and discusses his plot to blackmail Di Xiaoyao into yielding the rosary by poisoning Xie Daoyun. Shenxiu requests Xi Sanmei not to cause severe injury to Xie Daoyun, since he wishes to court her. Xi Sanmei reluctantly agrees and leaves, unaware that Shenxiu is actually Xie Yan of the Mo Qing Sect.

Months ago, Qin Wuque was captured and killed by Ge Huaiyu of the Xin Mo Sect. Later, Ge Huaiyu was killed by Xie Yan who obtained a notebook containing all the profiles of Ge Huaiyu's identities, and successfully impersonated Shenxiu. Disgusted with Xi Sanmei's malice, Xie Yan plots his assassination.

The next day, Xi Sanmei lures Di Xiaoyao and his retinue away from Ji Ye by spreading rumours about some fragments of the Soaring Hornless Dragon Scripture being discovered. He then spends the next few days attacking Xie Daoyun and Xie Yan, and the duo evade him. However, Xie Yan's attempts to court Xie Daoyun end in vain and Xi Sanmei loses his patience. One night, he decides to rape Xie Daoyun. In the ensuing skirmish, Xie Yan and Xie Daoyun escape but Xi Sanmei poisons them. Just then the three monks from the Vermilion Bird Temple arrive at the request of Xie Yan and trap Xi Sanmei using the Three Heavenly Stars Demon Execution Formation. Xi Sanmei angrily exposes Shenxiu's identity as Qin Wuque. Xie Yan flees with Xie Daoyun as the monks visit on the enraged Xi Sanmei. Xi Sanmei dauntlessly escapes the formation of the three monks, even forcing them to retreat and recuperate for a while. However, this reduces his cultivation base to the first layer of the Innate Realm.

Xi Sanmei intercepts Xie Yan and Xie Daoyun. He viciously injures Xie Yan's heart and coerces him to maim Xie Daoyun. Xie Yan defies the order and instead tears his own chest, extracting the virulent worm from his heart. Xie Yan promises to save Xie Daoyun and coaxes her to rest. Blazing with fury, Xie Yan confronts Xi Sanmei and the two fight a bloody duel. Despite Xi Sanmei's superior prowess as an Innate Realm expert, he is shocked when Xie Yan shrugs off his attacks. As the battle rages, Xi Sanmei begins to panic and attempts to flee from his berserk opponent. Xie Yan pounces on the hapless Xi Sanmei and impales him with the Finger Of Flowery Swords, killing the villain. Xi Sanmei never knew of Shenxiu's true identity as Xie Yan.

In the aftermath, Xie Yan admits to Cyany that Xi Sanmei was the strongest opponent he had ever fought. He orders Cyany to disfigure Xi Sanmei's corpse. Xie Yan heals Xie Daoyun's injuries and leaves before she can wake up.
