Fistful of Vengeance

As Kai (actor name), Lu Xin, and Tommy venture into the vibrant cityscape of Bangkok, driven by a sense of vengeance and determination, they embark on a perilous quest to unravel the mystery surrounding the brutal murder of Tommy's sister, Jenny. The investigation leads them to an ancient talisman etched with cryptic symbols, which serves as a trailblazing guide to Thailand. Here, they cross paths with biotech mogul William Pan, who harbors a secret request that sets their journey ablaze. He implores the trio to locate and capture Ku An Qi, his twin sister and the ruthless jiangshi matriarch of the underworld, whose insatiable thirst for qi has empowered her to orchestrate a global takeover.

William's tale unfolds like a intricate tapestry, revealing that he and Ku are direct descendants of Pangu, the mythical being who sculpted the universe. Their lineage is marked by a dual heritage, with one talisman in William's possession and another, once belonging to Ku, now held by Tommy. The billionaire explains that Ku had struck down Jenny while seeking out Kai, the current Wu Assassin, but lost her own talisman during their confrontation. With both relics at his disposal, William proposes using them to disable Ku and restore balance to the cosmos.

The trio agrees to aid William, and as they join forces with Tommy's friend Preeya, a plan unfolds to abduct Ku from a high-stakes meeting with the city's Triad bosses. However, Ku unleashes her mind control powers, turning the building's occupants against the group, while Kai is simultaneously ambushed by Zan, his long-standing adversary who serves Ku. Their escape is aided by Zama, an Interpol agent and Lu Xin's former lover, who shares a common goal: capturing Ku.

As they regroup in Preeya's ancestral village, the shaman reveals a startling truth: William has secretly aligned himself with Ku to revive Pangu, seeking to reshape the world according to their design. To achieve this, they require both talismans and Kai's vital qi. This revelation plunges the group into a maelstrom of uncertainty, as they must reassess their allegiances and confront the true nature of their quest.

As a tantalizing promise of resurrection takes hold, William and Ku cunningly convince Preeya to pilfer the talisman from Tommy's grasp, dangling the possibility of bringing her deceased loved ones back to life before her eyes. Seizing the opportunity, she harnesses some of Kai's mystical energy, imbuing herself with an otherworldly vitality. Meanwhile, chaos erupts as Ku's cohorts launch a brutal assault on the village, prompting Kai, Lu Xin, Tommy, and Zama to make a daring escape. The quartet embarks on a perilous journey to track down William and Ku, tracing their steps to an archaeological excavation site where the storied history of the first Wu Assassin's legendary battle with Pangu unfolds.

In a poignant twist, a contrite Preeya lends her support to Tommy and Zama as they engage in a fierce showdown against Ku, while Kai finds himself locked in mortal combat with the formidable Zan. Though Kai emerges victorious, claiming Zan's life, his triumph is short-lived as William's manipulation of Kai's energy allows him to resurrect Pangu, who then takes possession of William's physical form. As a result, a mind-controlled Lu Xin is pitted against Kai, forcing our hero to employ all his wits and strength to snap his friend out of the trance-like state.

In the aftermath of this intense confrontation, Kai and Pangu engage in an epic battle, ultimately securing a hard-won victory that leaves William dispossessed and trapped underground. With their triumph celebrated amidst the sun-kissed backdrop of a day at the beach, Kai drops a bombshell announcement: his next challenge lies in vanquishing a malevolent necromancer, casting a foreboding shadow over the horizon.
