Stars Fall on Earth: Earth Guest's Magical Continent

Core settings Protagonist: Lin Ye (a graduate student in earth botany, who carries a portable plant specimen box when traveling through time, and is good at using earth science knowledge to analyze magical phenomena) Magic Continent: "Essos Continent" is divided into five major geographical sections (Misty Forest, Red Sand Desert, Permafrost Snow Mountain, Ancient Magic Plain, Abyss Fissure). The magic system includes three categories: "Elemental Magic (Fire/Water/Wind/Earth)", "Blood Magic (Orcs/Elves)" and "Ancient Pattern Magic (Dwarves/Ancient Ruins)". The continent hides the crisis of "magic energy decline". Main clue: The "Starfall Stones" (crystals discovered by earth archeology) obtained while traveling through the forest are the key to returning home. You need to collect the "Stardust Fragments" scattered across the continent to activate them. The fragments are hidden in the core secret realms of each area.
