Green Hairy Frog

I have stopped writing exams recently. Wang Qi is a master's student at the University of Arizona, focusing on Amazon geology. A roommate from Spain came up with the slang term for the green hairy frog and jokingly called it a species in the Amazon basin. However, Wang Qi could not find any information about the green hairy frog, so he laughed at himself and thought that this might be another cultural collision between Chinese and Spanish people. His graduation project required him to collect data in the Amazon Basin. When an accident occurred, he failed to evacuate safely during the Amazon River floods. When he thought he was dead, he miraculously traveled to Barcelona in 1493. His new identity was Salvador Wilda, a medical professional at the University of Salamanca. At this time, Columbus had just returned to Spain after discovering the New World, and planned to start a new voyage. Salvador was studying with the royal physician Diego Chanca, who was chosen to be one of the ship's doctors who would conquer the New World, and Salvador would sail with him. . . .
