Mei and MK enter a street race that will grant the winner "immortality" but a disagreement has them competing against each other.
After hearing MK mentioning a Peach of Immortality, Pigsy questions MK and Mei on what they were talking about, causing MK and Mei to get mad at Pigsy for not knowing what the Peaches of Immortality are. Tang then explains that the Immortal Peaches grew in the heavenly realm and were protected by the gods before being taken by the Monkey King so he can become immortal. When Pigsy said that he thought that the Monkey King was already immortal, Mei says that doesn't matter and that the winner of the next Great Wall Race will win an Immortal Peach.
Meanwhile, Red Son tells the Demon Bull King and Princess Iron Fan about the prize of the Great Wall Race. However, when the Demon Bull King and Princess Iron Fan rejected Red Son's idea about winning an Immortal Peach, Red Son leaves in frustration and decided to win the Peach of Immortality for himself. Although, the Demon Bull King and Princess Iron Fan changed their minds at the last minute so they can beat their son at the race.
