After HP Time Travel, I Started a Career in the Magical World

CP Malfoy, a descendant of an ancient family, is from the Snake House Lin Weiwei, a graduate student in the history department, came into contact with a mysterious ancient book and traveled through time to become Serena Shadowweaver, the baby of the ancient wizard family "Shadowweaver". The family has the powerful talents of "Invisibility" and "Eclipse Curse", but it has also fallen into a desperate situation of population decline due to magic backlash syndrome. It is also monitored by the Ministry of Magic and feared by pure-blood families. With the memory of the Harry Potter world in her previous life, Serena relied on her rationality and research instinct to enter Slytherin during the sorting at Hogwarts. Becoming friends with the three little ones and falling in love with Draco Malfoy, they fought against Voldemort together. She discovered that the moon necklace left behind by her mother concealed the secrets of the contract with the first generation of the family. The fragments of ancient books she studied in her childhood were closely related to the family sacred object "Code of Night Shadows". Faced with the current situation that his father died young due to a conflict with Death Eaters and his mother was tortured by illness, how will this time-travel heir integrate modern wisdom and ancient magic to break the family curse and lead the Shadowweaver family to overcome many crises and rebuild glory in a magical world shrouded in the shadow of Voldemort?
