Nick, I mean Agent Nick, must find a 6000-year-old person (that's right, a 6000-year-old person). If you want to know if he succeeds or not, you have to watch the episode.
Agent Nick passes out in the middle of nowhere and gets dragged along the road for like, a good 3km. He also completes his final mission (for the time being, at least), which makes him go crazy and run around in public, screaming like a maniac.
In this episode, Agent Nick's missions take him on a wild goose--er, chicken--chase, to find a rooster whose call can be heard in three countries simultaneously. Oh yeah, he also has to find a shirt made of corn.
Agent Nick explores the automotive industry, of which Jilin Province is the leader in China. He sets out on a search to find a car that Chairman Mao has sat in before. Does he find what he's looking for? You'll have to watch the episode to find out.
Finally, Agent Nick's hard work has paid off. This episode is the finale of Exploring China Jilin, and his mission this time is to take two weeks off and experience the lifestyle enjoyed by the citizens of Jilin. He visits the largest shopping mall in the world, meets a 110-year-old man, and lots more.
Mr. Ding sends Nick--hereafter known as Agent Nick--on his first set of missions. This time he is to find his way to the Qingpu district of Shanghai, where his first mission is to find and send a letter at a post office from the Qing Dynasty.
