On the surface, he is a scholar who writes for magazines, but in fact he is a contemporary writer of the "World Book". Golden Finger [Book of the World]: A mysterious jade tablet passed down from Ding Chen's ancestors, which was awakened when he was determined to change the destiny of the country with his pen. This book is connected to a unique "underworld" - it is not a place of punishment, but a knowledge base of the multidimensional universe.
