Unexpectedly, they traveled back to the age of dinosaurs. They successively met Queen Aya, Monk Erkong, and Princess Shana. During the capture of a pterosaur, Wang Li, Shana, and the pterosaur became friends, and they helped quell the war between the Aya people and the ape-men. Together with the other expedition members, Wang Li defeated the fierce monster on the iceberg.
