The True Young Master Fell in Battle, Then Became a Blood Princess and Slaughtered His Enemies

Gu Ci is the real young master of the Gu family, who was lost outside the family and later found. But when he returns, his entire family despises him. His parents dote on their scheming adopted son, while his five older sisters beat and berate Gu Ci, all so they can use him as a walking blood bank for the adopted son, who has a terminal illness. On the night of the college entrance exams, Gu Ci signs a declaration severing ties with his family. But while delivering takeout late that night, he is pierced through the heart by a great demon as he shields a mysterious girl. As he lies dying, he smiles. At last, he's free from this broken life. But he doesn't die. The girl turns out to be a princess of the Abyss who has been sleeping for a thousand years. To repay his kindness, she fuses the source of her divinity with Gu Ci. When he opens his eyes again, the lowly Gu Ci is gone. In his place is a cool, silver-haired girl with red eyes and god-tier supernatural powers: Gu Qixue. From then on, the city has a peerless goddess who slaughters her way through forbidden zones, untouchable and beyond reach. When the Gu family learns of Gu Ci's death, they completely lose their minds. His haughty eldest sister clutches his bloodstained clothes and weeps. His biased parents kneel in the rain, begging him to come back. Then one day, with the family's survival at stake, the Gu family humbly kneels before the aloof goddess who appeared out of nowhere and begs for help. They never would have guessed that this white-haired girl, a distant goddess they revere, is the very younger brother they drove to his death with their own hands.
