Even a single fruit fly can sense the Earth's magnetic field. Migratory birds crossing continents can undertake long journeys thanks to their magnetic compass. How much do we know about the history of the land we tread upon? The Korean Peninsula, our homeland, was formed from miraculous coincidences and the accumulation of time. The Insubong Peak of Bukhansan Mountain, the folds of Baengnyeong Island, the sheer limestone cliffs, even a single stone from a volcanic island, all hold a unique magnetism that tells us where and how they originated on Earth. Why are the trilobite fossils from Taebaek-Australia-Bhutan twins? Why are the coastal cliffs of the five West Sea islands called a 1-billion-year-old geological museum? Does the Insubong rock, climbed with great effort, erode 1 meter every 100,000 years, shaping Seoul? Why is magma a magician? Rocks are crucial codes for reading life, and remain an unexplored territory. Recent travel patterns have shifted from merely enjoying scenery like walking the Olle Trail to geological trails. This is likely because people want to satisfy their curiosity about the history of the land they walk on. The beautiful and grand geological history of the Korean Peninsula is highly dynamic, and almost all core areas are designated as natural monuments. Using 'rocks' that hold the Earth's secrets as a key, we explore the life networks we face today and read the time capsules of extinction and climate change embedded in the strata. We attempt a 'Korean Peninsula Natural History Textbook' revealed through visuals, combining 8K ultra-high-definition live-action with global perspective graphics. From the perspective of a cosmic star traveler, we begin at the sand dunes of Daejakdo Island 2.5 billion years ago, explore the 1-billion-year-old coasts of Sochong and Baengnyeong Islands, and cross the equatorial sea by boat to encounter trilobites in the 500-million-year-old limestone valleys of Gangwon. As members of the Homo sapiens species, from the order Primates within the class Mammalia of the phylum Chordata, we visit the wetlands of pterosaurs and dinosaurs 100 million years ago, and witness underwater explosions and a night of firestorms on a volcanic island through augmented reality. We explore the uplift and erosion of granite in bizarre cliffs like Bukhansan and Seorak Mountains, and reflect on the history of the land we live on within the subway of metropolitan Seoul. A free and life-affirming odyssey that transcends time and space... The 3-billion-year secrets of the Korean Peninsula unfold outside the train window amidst the hustle and bustle of a single day in Seoul.
