[The Rebirth of the Red Chamber: The Counterattack of the Abandoned Child of the Lin Family]

This book was an ancient romance novel written by the author, the God of War. The female protagonist, Lin Zong, was a modern avenger, but she was reborn in the world of the Red Chamber of the Qing Dynasty. She became the eldest son of Lin Ruhai, who should have died early and was almost completely unknown, and Lin Daiyu's half-brother, Lin Xuanyu. The following plot revolved around Lin Xuanyu's counterattack. In a dangerous environment, his mother's inferiority, the ruthlessness of the Lin family's elders, and Jia Min's jealousy and poison put him in danger step by step. In the new feudal chaotic world, he made a comeback and dealt with his family and love. If you like fantasy stories and Dream of the Red Chamber, then " Reborn in the Dream of the Red Chamber: The Counterattack of the Abandoned Child of the Lin Family " is a good choice.
