Answer the following question: What is the answer for the question: What is the last name of the person that Lupo tries to get to participate in the robbery? from the following article ?  South Boston teenager Jason Tripitikas is a fan of martial arts films and awakens from a dream of a battle between the Monkey King and celestial soldiers in the clouds. He visits a pawn shop in Chinatown to buy wuxia DVDs and discovers a golden staff. On his way home, Tripitikas is harassed by some hooligans, whose leader Lupo attempts to use him to help them rob the shop-owner Hop, who is shot by Lupo. Hop tells Tripitikas to deliver the staff to its rightful owner and Tripitikas flees with the staff. He is cornered on the rooftop before being pulled off the roof by the staff. When Tripitikas regains consciousness, he finds himself in a village in ancient China that is under attack by armored soldiers. The soldiers see his staff and attempt to seize it. He is saved by the inebriated traveling scholar Lu Yan, a supposed "immortal," who remains alert and agile even when drunk. Lu tells him the story of the rivalry between the Monkey King and the Jade Warlord. The Warlord tricked the King into setting aside his magic staff, Ruyi Jingu Bang, and transformed the immortal into a stone statue, but the King cast his staff far away before the transformation. Lu ends the tale with a prophecy about a "Seeker" who will find the staff and free the King. Just then, they are attacked by the Warlord's men again, but manage to escape with the help of Golden Sparrow, a young woman. She reveals that her family was murdered by the Warlord, against whom she has sworn revenge.
Answer:
Tripitikas
