A modern magic graduate student accidentally traveled to the Arcane Continent and became a useless magic apprentice who was dropped out of school. After awakening the "time and space sign-in system", he can randomly obtain magic materials/forbidden spell fragments/other world knowledge every day. In order to find out the truth about time travel, he disguised himself as a mute servant and sneaked into Xinghui Magic Academy, and accidentally exchanged the soul of the missing genius magician. Use modern scientific thinking to reconstruct the Magic Network system, use the abyss fire obtained by signing in to ignite the fire of truth, expose the "traveler control theory" conspiracy in the Holy Demon War, and finally use forbidden time magic to reverse the era and establish an interdimensional magic federation.
