This book is an alternate history work based on the world view of the game "Genshin Impact". From the perspective of a scholar, this book systematically combs the long historical process of the Teyvat continent from the ancient dragon era to the emergence of the Seven Kingdoms, including the rule of the seven dragon kings, the advent of Phanes, the rise and fall of the mythical era, the cruelty of the demon war, and the formation of the seven kingdoms. Through the study of ancient books and the revelation of the World Tree, the truth buried by time is restored, showing a grand and tragic epic world. The book pays special attention to the fate of key figures at historical turning points and the underlying reasons behind the rise and fall of civilization, providing readers with a general history of Teyvat that is both academic and literary.
