Task: Question Generation
Input (English):  Two years after the events of Blade, a pandemic known as the "Reaper virus" has spread through the vampire community. Infected vampires are turned into Reapers, mutants immune to all vampire weaknesses with the exception of bright light. Unable to contain the Reapers, vampire lord Eli Damaskinos sends two emissaries, Asad and Nyssa, to seek the aid of vampire hunter Blade and his team, consisting of weaponsmith Abraham Whistler and his assistant Scud. Damaskinos introduces them to the Bloodpack, a group of vampires trained for the sole purpose of killing Blade. In addition to Asad and Nyssa, the Bloodpack consists of Reinhardt, Chupa, Snowman, Verlaine, her lover Lighthammer, and Priest. To keep them in line, Blade plants an explosive charge on the back of Reinhardt's head.
On Blade's advice, the team starts by investigating a local nightclub frequented by vampires. When they do encounter Reapers, they soon discover that their weapons and powers are completely ineffective. Blade is forced to kill Priest after he becomes infected, Lighthammer is wounded, Whistler deserts his post, and Scud barely survives a Reaper attack by using UV lights to scare them off. One of the Reapers, Jared Novak, attacks and nearly kills Blade before a burst of sunlight forces him to retreat. Whistler reappears and explains that he has been tracking the Reapers to a central nest in the sewers. Having learned of their prime weakness, he and Scud create UV projectors for the team.
While searching for the nest, Lighthammer succumbs to infection, killing Snowman and Verlaine before dying of light exposure. Chupa turns on Whistler and attacks him, only to die when a group of Reapers attracted to his scent tear him apart. Asad is ambushed, dragged underwater, and killed. Using a special UV emitter, Blade kills all of the Reapers with the exception of Novak and rescues Reinhardt and Nyssa, bringing them to Whistler.
Damaskinos betrays Blade and Whistler, revealing that he created the Reaper virus in order to create a new race of vampires and that Nomak is in fact his son. Scud turns out to be a familiar loyal to Reinhardt, who also works for Damaskinos. Explaining that he always knew of Scud's true allegiance, Blade kills him with the bomb he placed earlier. Damaskinos then orders his scientists to dissect Blade so that he can learn how to replicate his abilities. After escaping his captors, Whistler brings Blade to a blood vault, where he regains enough strength to kill Reinhardt and his men.
Seeking revenge, Nomak tracks Damaskinos to his private heliport and kills him. He then bites Nyssa, infecting her with the virus. Blade confronts Nomak and helps him commit suicide to end his suffering. Fulfilling Nyssa's dying wish, Blade takes her outside, where she dies while watching the sun rise. The movie ends with Blade in London, where he kills Rush, a vampire he encountered earlier in the movie.
Output (English): What device does blade use to kill all the Reapers with the exception of Novak?
